After a fuse is replaced

●

When installing the lid, make sure 

that the tab is installed securely.

●

If the lights do not turn on even 

after the fuse has been replaced, 

a bulb may need replacement. 

(

P.463)

●

If the replaced fuse blows again, 

have the vehicle inspected by 

your Toyota dealer.

■

If there is an overload in a cir-

cuit

The fuses are designed to blow, pro-

tecting the wiring harness from 

damage.

■

When replacing light bulbs

Toyota recommends that you use 

genuine Toyota products designed 

for this vehicle.

Because certain bulbs are con-

nected to circuits designed to pre-

vent overload, non-genuine parts of 

parts not designed for this vehicle 

may be unusable.

WARNING

■

To prevent system break-

downs and vehicle fire

Observe the following precau-

tions.

Failure to do so may cause dam-

age to the vehicle, and possibly a 

fire or injury.

●

Never use a fuse of a higher 

amperage rating than that indi-

cated, or use any other object in 

place of a fuse.

●

Always use a genuine Toyota 

fuse or equivalent.

Never replace a fuse with a 

wire, even as a temporary fix.

●

Do not modify the fuses or fuse 

boxes.

NOTICE

■

Before replacing fuses

Have the cause of electrical over-

load determined and repaired by 

your Toyota dealer as soon as 

possible.

Light bulbs

You may replace the follow-
ing bulbs yourself. The diffi-
culty level of replacement 
varies depending on the 
bulb. If necessary bulb 
replacement seems difficult 
to perform, contact your 
Toyota dealer.

For more information about 
replacing other light bulbs,

rear side marker lights and back-up 

lights consist of a number of LEDs. 

If any of the LEDs burn out, take 

your vehicle to your Toyota dealer to 

have the light replaced.

■

Condensation build-up on the 

inside of the lens

In certain situations, such as when 

driving in the rain or when washing 

the vehicle, condensation may form 

on the inner side of the headlight 

lens and other lights. As each light 

has a ventilation hole, moist air may 

enter. If the ambient temperature is 

low, condensation may form tempo-

rarily, but it will dissipate as the 

inside of the light is warmed up. As 

the condensation is due to a phe-

nomenon similar to windows fogging 

in the rain, it does not indicate a 

malfunction.
Contact your Toyota dealer for more 

information in the following situa-

tions:

●

Large drops of water have built up 

on the inside of the lens.

●

Water has built up inside the 

headlight.

8-2.Steps to take in an emergency

If your vehicle needs 

to be towed

If towing is necessary, we 
recommend having your 
vehicle towed by your Toy-
ota dealer or commercial 
towing service, using a 
wheel-lift type truck or flat-
bed truck.

Use a safety chain system 
for all towing, and abide by 
all state/provincial and local 
laws.

WARNING

Observe the following precau-

tions.

Failure to do so may result in 

death or serious injury.

■

When towing the vehicle

Be sure to transport the vehicle 

with the front wheels raised or 

with all four wheels raised off the 

ground. If the vehicle is towed 

with the front wheels contacting 

the ground, the drivetrain and 

related parts may be damaged or 

electricity generated by the opera-

tion of the motor may cause a fire 

to occur depending on the nature 

of the damage or malfunction.

■

While towing

●

When towing using cables or 

chains, avoid sudden starts, etc. 

which place excessive stress on 

the towing eyelets, cables or 

chains. The towing eyelets, 

cables or chains may become 

damaged, broken debris may hit 

people, and cause serious dam-

age.

●

Do not turn the power switch off.

There is a possibility that the 

steering wheel is locked and 

cannot be operated.

■

Installing towing eyelets to 

the vehicle

Make sure that towing eyelets are 

installed securely.

If not securely installed, towing 

eyelets may come loose during 

towing.

NOTICE

■

To prevent damage to the 

vehicle when towing using a 

wheel-lift type truck

●

Do not tow the vehicle from the 

rear when the power switch is 

off. The steering lock mecha-

nism is not strong enough to 

hold the front wheels straight.

●

When raising the vehicle, 

ensure adequate ground clear-

ance for towing at the opposite 

end of the raised vehicle. With-

out adequate clearance, the 

vehicle could be damaged while 

being towed.

■

To prevent damage to the 

vehicle when towing with a 

sling-type truck

Do not tow with a sling-type truck, 

either from the front or rear.

WARNING

■

If both the ABS and the brake 

system warning lights remain

Stop your vehicle in a safe place 

immediately and contact your Toy-

ota dealer.

The vehicle will become 

extremely unstable during brak-

When steering wheel operations 

are heavier than usual, grip the 

steering wheel firmly and operate 

it using more force than usual.

WARNING

■

If the tire pressure warning 

light comes on (vehicles with 

a tire pressure warning sys-

tem)

Be sure to observe the following 

precautions.

Failure to do so could cause a 

loss of vehicle control and result 

in death or serious injury.

●

Stop your vehicle in a safe place 

as soon as possible. Adjust the 

tire inflation pressure immedi-

ately.

●

Vehicles with a compact spare 

tire: If the tire pressure warning 

light comes on even after tire 

inflation pressure adjustment, it 

is probable that you have a flat 

tire. Check the tires. If a tire is 

flat, change it with the spare tire 

and have the flat tire repaired by 

the nearest Toyota dealer.

●

Vehicles with emergency tire 

puncture repair kit: If the tire 

pressure warning light comes 

on even after tire inflation pres-

sure adjustment, it is probable 

that you have a flat tire. Check 

the tires. If a tire is flat, repair 

the flat tire by using emergency 

tire puncture repair kit.

●

Avoid abrupt maneuvering and 

braking.

If the vehicle tires deteriorate, 

you could lose control of the 

steering wheel or the brakes.

■

If a blowout or sudden air 

leakage should occur (vehi-

cles with a tire pressure warn-

ing system)

The tire pressure warning system 

may not activate immediately.

■

Maintenance of the tires

Each tire, including the spare (if 

provided), should be checked 

monthly when cold and inflated to 

the inflation pressure recom-

mended by the vehicle manufac-

turer on the vehicle placard or tire 

inflation pressure label (tire and 

load information label). (If your 

vehicle has tires of a different size 

than the size indicated on the 

vehicle placard or tire inflation 

pressure label [tire and load infor-

mation label], you should deter-

mine the proper tire inflation 

pressure for those tires.)

As an added safety feature, your 

vehicle has been equipped with a 

tire pressure monitoring system 

(TPMS-tire pressure warning sys-

tem) that illuminates a low tire 

pressure telltale (tire pressure 

warning light) when one or more 

of your tires is significantly 

under-inflated. Accordingly, when 

the low tire pressure telltale (tire 

pressure warning light) illumi-

nates, you should stop and check 

your tires as soon as possible, 

and inflate them to the proper 

pressure. Driving on a signifi-

cantly under-inflated tire causes 

the tire to overheat and can lead 

to tire failure. Under-inflation also 

reduces fuel efficiency and tire 

tread life, and may affect the vehi-

cle’s handling and stopping ability.

Please note that the TPMS (tire 

pressure warning system) is not a 

substitute for proper tire mainte-

nance, and it is the driver’s 

responsibility to maintain correct 

tire pressure, even if under-infla-

tion has not reached the level to 

trigger illumination of the TPMS 

low tire pressure telltale (tire pres-

sure warning light).

WARNING

Your vehicle has also been 

equipped with a TPMS (tire pres-

sure warning system) malfunc-

tion indicator to indicate when the 

system is not operating properly. 

The TPMS (tire pressure warning 

system) malfunction indicator is 

combined with the low tire pres-

sure telltale (tire pressure warning 

light). When the system detects a 

malfunction, the telltale will flash 

for approximately one minute and 

then remain continuously illumi-

nated. This sequence will con-

tinue upon subsequent vehicle 

start-ups as long as the malfunc-

tion exists. When the malfunction 

indicator is illuminated, the sys-

tem may not be able to detect or 

signal low tire pressure as 

intended.

TPMS (tire pressure warning sys-

tem) malfunctions may occur for a 

variety of reasons, including the 

installation of replacement or 

alternate tires or wheels on the 

vehicle that prevent the TPMS 

(tire pressure warning system) 

from functioning properly. Always 

check the TPMS (tire pressure 

warning system) malfunction tell-

tale after replacing one or more 

tires or wheels on your vehicle to 

ensure that the replacement or 

alternate tires and wheels allow 

the TPMS (tire pressure warning 

system) to continue to function 

properly.

NOTICE

■

To ensure the tire pressure 

warning system operates

NOTICE

■

If “High Power Consumption 

Partial Limit on AC/Heater 

Operation” is displayed fre-

quently

There is a possible malfunction 

relating to the charging system or 

the 12-volt battery may be deteri-

orating. Have the vehicle 

inspected by your Toyota dealer.

If you have a flat tire 

(vehicles without 

spare tire)

Your vehicle is not equipped 
with a spare tire, but instead 
is equipped with an emer-
gency tire puncture repair 
kit.

A puncture caused by a nail 
or screw passing through 
the tire tread can be 
repaired temporarily using 
the emergency tire puncture 
repair kit. (The kit contains a 
bottle of sealant. The seal-
ant can be used only once 
to temporarily repair one 
tire without removing the 
nail or screw from the tire.) 
After temporarily repairing 
the tire with the kit, have the 
tire repaired or replaced by 
your Toyota dealer.

WARNING

■

If you have a flat tire

Do not continue driving with a flat 

tire.

Driving even a short distance with 

a flat tire can damage the tire and 

the wheel beyond repair, which 

could result in an accident.

Emergency tire puncture repair 

kit

●

The emergency tire puncture 

repair kit is for filling the car tire 

with air.

●

The sealant has a limited life 

span. The expiry date is marked 

on the bottle. The sealant should 

be replaced before the expiry 

date. Contact your Toyota dealer 

for replacement.

●

The sealant stored in the emer-

gency tire puncture repair kit can 

be used only once to temporarily 

repair a single tire. If the sealant in 

the bottle and other parts of the kit 

have been used and need to be 

replaced, contact your Toyota 

dealer.

●

The compressor can be used 

repeatedly.

●

The sealant can be used when the 

outside temperature is from -40°F 

(-40°C) to 140°F (60°C).

●

The kit is exclusively designed for 

size and type of tires originally 

installed on your vehicle. Do not 

use it for tires that a different size 

than the original ones, or for any 

other purposes.

●

If the sealant gets on your clothes, 

it may stain.

●

If the sealant adheres to a wheel 

or the surface of the vehicle body, 

the stain may not be removable if 

it is not cleaned at once. Immedi-

ately wipe away the sealant with a 

wet cloth.

●

During operation of the repair kit, 

a loud operation noise is pro-

duced. This does not indicate a 

malfunction.

●

WARNING

■

Do not drive the vehicle with 

a flat tire

Do not continue driving with a flat 

tire.

Driving even a short distance with 

a flat tire can damage the tire and 

the wheel beyond repair.
Driving with a flat tire may cause a 

circumferential groove on the side 

wall. In such a case, the tire may 

explode when using a repair kit.

■

When fixing the flat tire

●

Stop your vehicle in a safe and 

flat area.

●

Do not touch the wheels or the 

area around the brakes immedi-

ately after the vehicle has been 

driven.

After the vehicle has been 

driven, the wheels and the area 

around the brakes may be 

extremely hot. Touching these 

areas with hands, feet or other 

body parts may result in burns.

●

Connect the valve and hose 

securely with the tire installed 

on the vehicle. If the hose is not 

properly connected to the valve, 

air leakage may occur as seal-

ant may be sprayed out.

●

If the hose comes off the valve 

while inflating the tire, there is a 

risk that the hose will move 

abruptly due to air pressure.

●

After inflation of the tire has 

completed, the sealant may 

splatter when the hose is dis-

connected or some air is let out 

of the tire.

●

Follow the operation procedure 

to repair the tire. If the proce-

dures not followed, the sealant 

may spray out.

●

Keep back from the tire while it 

is being repaired, as there is a 

chance of it bursting while the 

repair operation is being per-

formed. If you notice any cracks 

or deformation of the tire, turn 

off the compressor switch and 

stop the repair operation imme-

diately.

●

The repair kit may overheat if 

operated for a long period of 

time. Do not operate the repair 

kit continuously for more than 

40 minutes.

●

Parts of the repair kit become 

hot during operation. Be careful 

handling the repair kit during 

and after operation. Do not 

touch the metal part connecting 

the bottle and the compressor. It 

will be extremely hot.

●

Do not attach the vehicle speed 

warning sticker to an area other 

than the one indicated. If the 

sticker is attached to an area 

where an SRS airbag is located, 

such as the pad of the steering 

wheel, it may prevent the SRS 

airbag from operating properly.

■

Driving to spread the liquid 

sealant evenly

Observe the following precautions 

to reduce the risk of accidents.

Failing to do so may result in a 

loss of vehicle control and cause 

death or serious injury.

●

Drive the vehicle carefully at a 

low speed. Be especially careful 

when turning and cornering.

●

If the vehicle does not drive 

straight or you feel a pull 

through the steering wheel, stop 

the vehicle and check the fol-

lowing.

NOTICE

■

When performing an emer-

gency repair

●

A tire should only be repaired 

with the emergency tire punc-

ture repair kit if the damage is 

caused by a sharp object such 

as nail or screw passing through 

the tire tread.

Do not remove the sharp object 

from the tire. Removing the 

object may widen the opening 

and disenable emergency repair 

with the repair kit.

●

The repair kit is not waterproof. 

Make sure that the repair kit is 

not exposed to water, such as 

when it is being used in the rain.

●

Do not put the repair kit directly 

onto dusty ground such as sand 

at the side of the road. If the 

repair kit vacuums up dust etc., 

a malfunction may occur.

■

Precautions for the emer-

gency tire puncture repair kit

●

The repair kit power source 

should be 12 V DC suitable for 

vehicle use. Do not connect the 

repair kit to any other source.

●

If fuel splatters on the repair kit, 

the repair kit may deteriorate. 

Take care not to allow fuel to 

contact it.

●

Place the repair kit in a storage 

to prevent it from being exposed 

to dirt or water.

●

Store the repair kit in the trunk 

out of reach of children.

●

Do not disassemble or modify 

the repair kit. Do not subject 

parts such as the air pressure 

indicator to impacts. This may 

cause a malfunction.

■

To avoid damage to the tire 

pressure warning valves and 

transmitters (vehicles with a 

tire pressure warning system)

When a tire is repaired with liquid 

sealants, the tire pressure warn-

ing valve and transmitter may not 

operate properly. If a liquid seal-

ant is used, contact your Toyota 

dealer or other qualified service 

shop as soon as possible. After 

use of liquid sealant, make sure to 

replace the tire pressure warning 

valve and transmitter when repair-

ing or replacing the tire. (

WARNING

■

Replacing a flat tire

●

Do not touch the disc wheels or 

the area around the brakes 

immediately after the vehicle 

has been driven. After the vehi-

cle has been driven the disc 

wheels and the area around the 

brakes will be extremely hot. 

Touching these areas with 

hands, feet or other body parts 

while changing a tire, etc. may 

result in burns.

●

Failure to follow these precau-

tions could cause the wheel 

nuts to loosen and the tire to fall 

off, resulting in death or serious 

injury.

• Have the wheel nuts tightened 

with a torque wrench to 76 ft•lbf 

(103 N•m, 10.5 kgf•m) as soon 

as possible after changing 

wheels.

• Do not attach a heavily dam-

aged wheel ornament, as it may 

fly off the wheel while the vehi-

cle is moving.

• When installing a tire, only use 

wheel nuts that have been spe-

cifically designed for that wheel.

• If there are any cracks or defor-

mations in the bolt screws, nut 

threads or bolt holes of the 

wheel, have the vehicle 

inspected by your Toyota 

dealer.

• When installing the wheel nuts, 

be sure to install them with the 

tapered ends facing inward.

possible.

■

Starting the hybrid system 

when the 12-volt battery is dis-

charged

The hybrid system cannot be started 

by push-starting.

■

To prevent 12-volt battery dis-

charge

●

Turn off the headlights and the 

audio system while the hybrid sys-

tem is off.

●

Turn off any unnecessary electri-

cal components when the vehicle 

is running at a low speed for an 

extended period, such as in heavy 

traffic.

■

When the 12-volt battery is 

removed or discharged

●

Information stored in the ECU is 

cleared. When the 12-volt battery 

is depleted, have the vehicle 

inspected at your Toyota dealer.

●

Some systems may require initial-

ization. (



P.552)

■

When removing the 12-volt bat-

tery terminals

When the 12-volt battery terminals 

are removed, the information stored 

in the ECU is cleared. Before 

removing the 12-volt battery termi-

nals, contact your Toyota dealer.

■

Charging the 12-volt battery

The electricity stored in the 12-volt 

battery will discharge gradually even 

when the vehicle is not in use, due 

to natural discharge and the drain-

ing effects of certain electrical appli-

ances. If the vehicle is left for a long 

time, the 12-volt battery may dis-

charge, and the hybrid system may 

be unable to start. (The 12-volt bat-

tery recharges automatically while 

the hybrid system is operating.)

■

When recharging or replacing 

the 12-volt battery

●

In some cases, it may not be pos-

sible to unlock the doors using the 

smart key system when the 

12-volt battery is discharged. Use 

the wireless remote control or the 

mechanical key to lock or unlock 

the doors.

●

The hybrid system may not start 

on the first attempt after the 

12-volt battery has recharged but 

will start normally after the second 

attempt. This is not a malfunction.

●

The power switch mode is memo-

rized by the vehicle. When the 

12-volt battery is reconnected, the 

system will return to the mode it 

was in before the 12-volt battery 

was discharged. Before discon-

necting the 12-volt battery, turn 

the power switch off.

If you are unsure what mode the 

516

8-2. Steps to take in an emergency

COROLLA HV_U

power switch was in before the 

12-volt battery discharged, be 

especially careful when recon-

necting the 12-volt battery.

■

When replacing the 12-volt bat-

tery

●

Use a 12-volt battery that con-

forms to European regulations.

●

Use a 12-volt battery with the 

same case size as the previous 

12-volt battery and an equivalent 

20 hour rate capacity (20HR) or 

greater.

• If the sizes differ, the 12-volt bat-

tery cannot be properly secured.

• If the 20 hour rate capacity is low, 

even if the time period where the 

vehicle is not used is a short time, 

the 12-volt battery may discharge 

and the hybrid system may not be 

able to start.

●

For details, consult your Toyota 

dealer.

WARNING

■

When removing the 12-volt 

battery terminals

Always remove the negative (-) 

terminal first. If the positive (+) ter-

minal contacts any metal in the 

surrounding area when the posi-

tive (+) terminal is removed, a 

spark may occur, leading to a fire 

in addition to electrical shocks 

and death or serious injury.

■

Avoiding 12-volt battery fires 

or explosions

Observe the following precautions 

to prevent accidentally igniting the 

flammable gas that may be emit-

ted from the 12-volt battery:

●

Make sure each jumper cable is 

connected to the correct termi-

nal and that it is not unintention-

ally in contact with any other 

than the intended terminal.

●

Do not allow the other end of 

the jumper cable connected to 

the “+” terminal to come into 

contact with any other parts or 

metal surfaces in the area, such 

as brackets or unpainted metal.

●

Do not allow the + and - clamps 

of the jumper cables to come 

into contact with each other.

●

Do not smoke, use matches, 

cigarette lighters or allow open 

flame near the 12-volt battery.

■

12-volt battery precautions

The 12-volt battery contains poi-

sonous and corrosive acidic elec-

trolyte, while related parts contain 

lead and lead compounds. 

Observe the following precautions 

when handling the 12-volt battery:

●

When working with the 12-volt 

battery, always wear safety 

glasses and take care not to 

allow any battery fluids (acid) to 

come into contact with skin, 

clothing or the vehicle body.

●

Do not lean over the 12-volt bat-

tery.

●

In the event that battery fluid 

comes into contact with the skin 

or eyes, immediately wash the 

affected area with water and 

seek medical attention. Place a 

wet sponge or cloth over the 

affected area until medical 

attention can be received.

●

Always wash your hands after 

handling the 12-volt battery sup-

port, terminals, and other bat-

tery-related parts.

●

Do not allow children near the

Add coolant if necessary.

Water can be used in an emer-

gency if coolant is unavailable.

6

Start the hybrid system and 
turn the air conditioning sys-
tem on to check that the radi-
ator cooling fans operate and 
to check for coolant leaks 
from the radiator or hoses.

The fans operate when the air con-

ditioning system is turned on imme-

diately after a cold start. Confirm 

that the fans are operating by 

checking the fan sound and air flow. 

If it is difficult to check these, turn 

the air conditioning system on and 

off repeatedly. (The fans may not 

operate in freezing temperatures.)

7

If the fans are not operating: 
Stop the hybrid system 
immediately and contact your 
Toyota dealer.
If the fans are operating: 
Have the vehicle inspected at 
the nearest Toyota dealer.

driven normally.

However, if the message appears 

again frequently, contact your Toy-

ota dealer.

WARNING

■

When inspecting under the 

hood of your vehicle

Observe the following precau-

tions. Failure to do so may result 

in serious injury such as burns.

●

If steam is seen coming from 

under the hood, do not open the 

hood until the steam has sub-

sided. The engine compart-

ment may be very hot.

8-2. Steps to take in an emergency

COROLLA HV_U

1

Stop the hybrid system. Set 
the parking brake and shift 
the shift lever to P.

2

Remove the mud, snow or 
sand from around the front 
wheels.

3

Place wood, stones or some 
other material under the front 
wheels to help provide trac-
tion.

4

Restart the hybrid system.

5

Shift the shift lever to D or R 
and release the parking 
brake. Then, while exercising 
caution, depress the acceler-
ator pedal.

■

When it is difficult to free the 

vehicle

Press the 

 switch to turn off 

TRAC.

WARNING

●

After the hybrid system has 

been turned off, check that the 

“READY” indicator is off. When 

the hybrid system is operating, 

the gasoline engine may auto-

matically start, or the cooling 

fans may suddenly operate 

even if the gasoline engine 

stops. Do not touch or approach 

rotating parts such as the fan, 

which may lead to fingers or 

clothing (especially a tie, a scarf 

or a muffler) getting caught, 

resulting in serious injury.

●

Do not loosen the coolant reser-

voir caps while the hybrid sys-

tem and radiator are hot.

High temperature steam or 

coolant could spray out.

NOTICE

■

When adding engine/power 

control unit coolant

Add coolant slowly after the 

hybrid system has cooled down 

sufficiently. Adding cool coolant to 

a hot hybrid system too quickly 

can cause damage to the hybrid 

system.

■

To prevent damage to the 

cooling system

Observe the following precau-

tions:

●

Avoid contaminating the coolant 

with foreign matter (such as 

sand or dust etc.).

●

Do not use any coolant additive.

If the vehicle becomes 

stuck

Carry out the following pro-
cedures if the tires spin or 
the vehicle becomes stuck 
in mud, dirt or snow:

WARNING

■

When attempting to free a 

stuck vehicle

If you choose to push the vehicle 

back and forth to free it, make 

sure the surrounding area is clear 

to avoid striking other vehicles, 

objects or people. The vehicle 

may also lunge forward or lunge 

back suddenly as it becomes free. 

Use extreme caution.

■

When shifting the shift lever

Be careful not to shift the shift 

lever with the accelerator pedal 

depressed.

This may lead to unexpected 

rapid acceleration of the vehicle 

that may cause an accident 

resulting in death or serious injury.

NOTICE

■

To avoid damaging the trans-

mission and other compo-

nents

●

Avoid spinning the front wheels 

and depressing the accelerator 

pedal more than necessary.

●

If the vehicle remains stuck 

even after these procedures are 

performed, the vehicle may 

require towing to be freed.
