8-2. Steps to take in an emergency

If you have a set of jumper (or 
booster) cables and a second 
vehicle with a 12-volt battery, 
you can jump start your vehicle 
by following the steps below.

1

 Confirm that the electronic 
key is being carried.

When connecting the jumper (or 

booster) cables, depending on the 

situation, the alarm may activate 

and doors locked. (P.78)

2

Open the hood. (P.404)

3

Connect a positive jumper cable clamp to   on your vehicle and 
connect the clamp on the other end of the positive cable to   on 
the second vehicle. Then, connect a negative cable clamp to   
on the second vehicle and connect the clamp at the other end of 
the negative cable to  .

Start the engine of the sec-
ond vehicle. Increase the 
engine speed slightly and 

maintain at that level for 
approximately 5 minutes to

recharge the 12-volt battery 
of your vehicle.

5

Open and close any of the 
doors of your vehicle with the 
power switch OFF.

6

Maintain the engine speed of 
the second vehicle and start 
the hybrid system of your 
vehicle by turning the power 
switch to ON.

7

Make sure the “READY” indi-
cator comes on. If the indica-
tor does not come on, contact 
your Toyota dealer.

8

Once the hybrid system has 
started, remove the jumper 
cables in the exact reverse 
order from which they were 
connected.

Once the hybrid system starts, 
have the vehicle inspected at 
your Toyota dealer as soon as 
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.524)

■

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 

488

8-2. Steps to take in an emergency

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 

12-volt battery.

■

Engine oil selection

“Toyota Genuine Motor Oil” is 
used in your Toyota vehicle. Use 
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to 
satisfy the following grade and 
viscosity.
Oil grade: API SN/RC multi-
grade engine oil
Recommended viscosity: SAE 
0W-16

Outside temperature

SAE 0W-16 is the best choice 
for good fuel economy and good 
starting in cold weather.
If SAE 0W-16 is not available, 
SAE 0W-20 oil may be used. 
However, it must be replaced 
with SAE 0W-16 at the next oil 
change.
Oil viscosity (0W-16 is explained 
here as an example):
• The 0W in 0W-16 indicates 

the characteristic of the oil 
which allows cold startability. 
Oils with a lower value before 
the W allow for easier starting 
of the engine in cold weather.

• The 16 in 0W-16 indicates the 

viscosity characteristic of the 
oil when the oil is at high tem-
perature. An oil with a higher 
viscosity (one with a higher 
value) may be better suited if 
the vehicle is operated at high 
speeds, or under extreme 
load conditions.
