P. 423)

■

When using the spare tire (vehicles without P245/60R20 tires)

As the spare tire is not equipped with a tire pressure warning valve and

transmitter, low inflation pressure of the spare tire will not be indicated by

the tire pressure warning system. Also, if you replace the spare tire after

the tire pressure warning light comes on, the light remains on.

When stowing the flat tire

Ensure that there is no object caught between the tire and the vehicle

underbody.

■

When replacing the tires

●

When removing or fitting the wheels, tires or the tire pressure warning

valve and transmitter, contact your Toyota dealer as the tire pressure

warning valve and transmitter may be damaged if not handled cor-

rectly.

mitters as well.

■

To avoid damage to the tire pressure warning valves and transmit-

ters

When a tire is repaired with liquid sealants, the tire pressure warning

valve and transmitter may not operate properly. If a liquid sealant is

used, contact your Toyota dealer or other qualified service shop as soon

as possible. Make sure to replace the tire pressure warning valve and

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 only: Open and close any of the
doors of your vehicle with the engine switch off.
Maintain the engine speed of the second vehicle and start the
engine of your vehicle by turning the engine switch to the “ON”
position (vehicles without a smart key system) or turning the engine
switch to IGNITION ON mode (vehicles with a smart key system).
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.

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 audio system while the engine is off.

●

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 recharging or replacing the battery

●

Vehicles with a smart key system: In some cases, it may not be possible to
unlock the doors using the smart key system when the battery is dis-
charged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.

●

The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.

●

Vehicles with a smart key system: The engine switch mode is memorized by
the vehicle. When the battery is reconnected, the system will return to the
mode it was in before the battery was discharged. Before disconnecting the
battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.

●

Make sure that the key is not inside the vehicle when recharging or replac-
ing the battery. The key may be locked in the vehicle if the alarm is acti-
vated. (

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 fans or engine drive belt.

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

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

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

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 fans and belts.

●

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

NOTICE

■

When adding engine coolant

Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. 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.
