WARNING

■

If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact your Toyota
dealer. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.

■

When the electric power steering system warning light comes on

The steering wheel may become extremely heavy.
When steering wheel operations are heavier than usual, grip the steering
wheel firmly and operate it using more force than usual.

■

If the tire pressure warning light comes on

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.
Vehicles with standard tires:

●

Stop your vehicle in a safe place as soon as possible. Adjust the tire

inflation pressure immediately.

●

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, change it with the spare tire and have the flat tire

repaired by the nearest Toyota dealer.

●

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,

you could lose control of the steering wheel or the brakes.

Vehicles with run-flat tires:

●

Decelerate to the lowest appropriate speed as soon as possible. Do

not drive over 50 mph (80 km/h).

●

Check and adjust the tire inflation pressure immediately.

●

If the tire pressure warning light comes on even after tire inflation pres-

sure adjustment, it is probable that you have a flat tire. Have the tire

replaced by the nearest Toyota dealer.

●

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

The tire pressure warning system may not activate immediately.

WARNING

■

Maintenance of the tires

Each tire, including the spare (if provided), should be checked monthly

when cold and inflated to the inflation pressure recommended by the

vehicle manufacturer on the vehicle placard or tire inflation pressure

label (tire and load information label). (If your vehicle has tires of a dif-

ferent size than the size indicated on the vehicle placard or tire inflation

pressure label [tire and load information label], you should determine

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 system) 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 significantly 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 vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-

stitute for proper tire maintenance, and it is the driver’s responsibility to

maintain correct tire pressure, even if under-inflation has not reached

the level to trigger illumination of the TPMS low tire pressure telltale (tire

pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-

ing system) malfunction indicator to indicate when the system is not

operating properly. The TPMS (tire pressure warning system) malfunc-

tion indicator is combined with the low tire pressure 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 continue upon subsequent vehicle start-ups

as long as the malfunction exists. When the malfunction indicator is illu-

minated, the system may not be able to detect or signal low tire pres-

sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-

ety 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 pres-

sure warning system) malfunction telltale after replacing one or more

tires or wheels on your vehicle to ensure that the replacement or alter-

nate tires and wheels allow the TPMS (tire pressure warning system) to

continue to function properly.

WARNING

■

Replacing a flat tire

●

Observe the following precautions.
Failure to do so may result in serious injury:
• Do not touch the disc wheels or the area around the brakes immedi-

ately after the vehicle has been driven.
After the vehicle 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.

• Remove the spare tire before jacking up the vehicle. If the spare tire

is removed after jacking up the vehicle, the tire carrier and the spare
tire may interfere with the jack and cause a serious accident.

●

Failure to follow these precautions 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.

• When installing a tire, only use wheel nuts that have been specifi-

cally designed for that wheel.

• If there are any cracks or deformations 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 end facing inward. (



P. 433)

●

For vehicles with power sliding door and/or power back door: In cases
such as when replacing tires, make sure to turn off the power sliding
door main switch (



P. 124) and/or the power back door main switch

(



P. 136). Failure to do so may cause the sliding door and/or the back

door to operate unintentionally if the power sliding door switch and/or
the power back door switch is accidentally touched, resulting in hands

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

NOTICE

■

When adding engine 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 additive.

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 transaxle and other components

●

Avoid spinning the wheels and pressing 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.

Engine oil selection

“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is explained here as an example):

• The 0W in 0W-20 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 20 in 0W-20 indicates the viscosity characteristic of the oil

when the oil is at high temperature. 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.

How to read oil container label:
The International Lubricant
Specification Advisory Commit-
tee (ILSAC) Certification Mark
is added to some oil containers
to help you select the oil you
should use.
