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 gen-
erated by the operation of the motor may
cause  a  fire  to  occur  depending  on  the
nature of the damage or malfunction.

Be  sure  to  transport  the  vehicle  with  all
four  wheels  raised  off  the  ground.  If  the
vehicle is towed with the tires contacting
the ground, the drivetrain or related parts
may be damaged, the vehicle may fly off

excessive stress on the towing eyelets, cables or chains. The towing eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple, and cause serious damage.

●

Do not turn the power switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.

■

Installing towing eyelets to the vehicle

●

The towing eyelets are only for the vehicle equipped with them. Do not use
the towing eyelets for another vehicle, and do not use the towing eyelets
for this vehicle on another vehicle.

WARNING

■

When the electric power steering system warning light comes on

When  the  light  comes  on  yellow,  the  assist  to  the  power  steering  is
restricted. When the light comes on red, the assist to the power steering is
lost  and  handling  operations  of  the  steering  wheel  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.

●

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

inflation pressure immediately.

●

Vehicles with emergency tire puncture repair kit: 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,

repair the flat tire by using emergency tire puncture repair kit.

●

Vehicles with 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.

●

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.

To ensure the tire pressure warning system operates properly

Do not install tires with different specifications or makers, as the tire

pressure warning system may not operate properly.
