Connect the jumper cables according to the following procedure:

Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.
Connect the clamp at the other end of the negative cable to a
solid, stationary, unpainted metallic point away from the battery
and any moving parts, as shown in the illustration.

Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the battery of your vehicle.
Vehicles with a smart key system: Open and close any of the doors
of your vehicle with the engine switch off.

Vehicles without a smart key system:
Maintain the engine speed of the second vehicle and turn the
engine switch to the “ON” position, then start the vehicle’s engine.
Vehicles with a smart key system:
Maintain the engine speed of the second vehicle and turn the
engine switch to IGNITION ON mode, then start the vehicle’s
engine.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
To install the engine cover, conduct the removal procedure in
reverse. After installing, check that the fixed pins are inserted
securely.

Once the engine starts, have the vehicle inspected at your Toyota
dealer as soon as possible.

■

Starting the engine when the battery is discharged
The engine cannot be started by push-starting.

■

To prevent battery discharge

●

Turn off the headlights and the air conditioning system while the engine is
stopped.

●

Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.

■

Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)

■

When exchanging the battery

●

Use a battery that conforms to European regulations.

●

Use a battery that the case size is same as the previous one (LN2), 20 hour
rate capacity (20HR) is equivalent (60Ah) or greater, and performance rating
(CCA) is equivalent (520A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi-

cle is not used is a short time, the battery may discharge and the engine
may not be able to start.

●

For details, consult your Toyota dealer.

442

WARNING

■

Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:

●

Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.

●

Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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 battery.

■

Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery:

●

When working with the 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 battery.

●

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 battery support, terminals, and
other battery-related parts.

●

Do not allow children near the battery.

NOTICE

■

When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fan or engine drive belt.

If your vehicle overheats

● The needle of the engine coolant temperature gauge (→P. 86)

enters the red zone or a loss of engine power is experienced (for
example, the vehicle speed does not increase).

● Steam comes out from under the hood.

Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.

Radiator
Cooling fan

If a large amount of coolant
leaks, immediately contact your
Toyota dealer.

The following may indicate that your vehicle is overheating.

Correction procedures

444

The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.

Reservoir
“FULL”
“LOW”

Add coolant if necessary.

Water can be used in an emer-
gency if coolant is unavailable.

Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operates and to check for coolant leaks
from the radiator or hoses.

The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is 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 fan may not operate in freezing temperatures.)

If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fan is operating:
Have the vehicle inspected at the nearest Toyota dealer.

WARNING

■

When inspecting under the hood of your vehicle
Observe the following precautions.
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 subsided. The engine compartment may be very hot.

●

Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.

●

Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
High temperature steam or coolant could spray out.

NOTICE

■

When adding coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.

■

To prevent damage to the cooling system
Observe the following precautions:

●

Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).

●

Do not use any coolant additives.

446

If the vehicle becomes stuck

Stop the engine. Shift the shift lever to P, and set the parking brake.
Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some other material under the front wheels
to help provide traction.
Restart the engine.
Shift the shift lever to D or R and release the parking brake. Then,
while exercising caution, depress the accelerator pedal.

■

When it is difficult to free the vehicle

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

Press

to turn off TRAC.

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 transmission and other components

●

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.
