Maintenance and care
Rotate the tires in the order shown.
Front
To equalize tire wear and extend tire
life, Toyota recommends that tire rota-
tion is carried out at the same interval
as tire inspection.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
 The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-infor-
mation display.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and
a warning light. ( P.342)
■Routine tire inflation pressure
checks
The tire pressure warning system does
not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display
the tire inflation pressure after the
engine switch is turned to ON. It may also take a few minutes to display the
tire inflation pressure after inflation
NOTICE
■If tire inflation pressure of each
tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
■Driving on rough roads
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in
tire inflation pressure, reducing the cushioning ability of the tires. In addi-
tion, driving on rough roads may
cause damage to the tires them- selves, as well as the vehicle’s
wheels and body.

registered by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
■Registering ID codes
The ID codes of the tire pressure warn- ing valve and transmitters for two sets of
wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels
of both normal tires and snow tires are registered beforehand.
In addition to the set of tire pressure
warning system sensor ID codes initially registered to the vehicle, a second set of
ID codes can be registered.
A second set of tire pressure warning system sensor ID codes can be regis-
tered at your Toyota dealer or repairer,
or another duly qualified and equipped professional. When 2 sets of ID codes
have been registered, either ID code set
can be selected.
1 Park the vehicle in a safe place
and turn the engine switch to
ON.
2 Press the tire pressure warning
reset switch 3 times within 3
seconds.
3 The tire pressure warning light
will illuminate for 3 seconds and
then blink 3 times.
4 The tire pressure warning light
will blink for 1 minute and then
illuminate.
5 When the ID code change has
completed, the tire pressure
warning light will turn off.
Check that tire pressures are displayed
on the multi-information display.

■Using the tire jack
Observe the following precautions.
Improper use of the tire jack may cause the vehicle to suddenly fall off
the jack, leading to death or serious
injury.
●Do not use the tire jack for any pur-
pose other than replacing tires or installing and removing tire chains.
●Do not use other tire jacks for replacing tires on this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle while it is sup-
ported by the jack.
●Do not start the engine or drive the
vehicle while the vehicle is sup-
ported by the jack.
●Do not raise the vehicle while
someone is inside.
●When raising the vehicle, do not put
an object on or under the jack.
●Do not raise the vehicle to a height
greater than that required to replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
●When lowering the vehicle, make sure that there is no-one near the
vehicle. If there are people nearby,
warn them vocally before lowering.

■Replacing light bulbs
●Turn off the lights. Do not attempt to
replace the bulb immediately after
turning off the lights. The bulbs become very hot and may cause
burns.
●Do not touch the glass portion of
the light bulb with bare hands.
When it is unavoidable to hold the glass portion, use and hold with a
clean dry cloth to avoid getting
moisture and oils on the bulb. Also, if the bulb is scratched or dropped,
it may blow out or crack.
●Fully install light bulbs and any
parts used to secure them. Failure
to do so may result in heat damage, fire, or water entering the light unit.
This may damage the lights or
cause condensation to build up on the lens.
■When changing the rear fog light or back-up lights
●Stop the engine and wait until the
exhaust pipes and surrounding parts have cooled down suffi-
ciently. The lights are located near
the exhaust pipe and touching a hot exhaust pipe and surrounding parts
can cause burns.
■To prevent damage or fire
●Make sure bulbs are fully seated
and locked.
●Check the wattage of the bulb
before installing to prevent heat damage.

When trouble arises
buzzer to sound even if a passenger
is not sitting in the seat.
●If a cushion is placed on the seat, the
sensor may not detect a passenger, and the warning light may not operate
properly.
■If the malfunction indicator lamp
comes on while driving
The malfunction indicator lamp will
come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empty, refuel the vehicle immediately. The mal-
function indicator lamp will go off after
several trips.
If the malfunction indicator lamp does
not go off, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as possi-
ble.
■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes
insufficient or the voltage temporarily
drops, the electric power steering sys- tem warning light may come on and the
warning buzzer may sound.
■When the tire pressure warning
light comes on
Check the tire inflation pressure and
adjust to the appropriate level. Pushing
the tire pressure wa rning reset switch will not turn off the tire pressure warning
light.
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may
come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In
this case, adjusting the tire inflation
pressure will turn off the warning light
(after a few minutes).
■Conditions that the tire pressure warning system may not function
properly
 P.304
■If the tire pressure warning light
frequently comes on after blinking for 1 minute
If the tire pressure warning light fre-
quently comes on after blinking for 1 minute when the engine switch is turned
to ON, have it checked by any author-
ized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Warning buzzer
In some cases, the buzzer may not be
heard due to being in a noisy location or audio sound.
WA R N I N G
■If both the ABS and the brake
system warning lights remain on
Stop your vehicle in a safe place immediately and contact any author-
ized Toyota retailer or Toyota author-
ized repairer, or any reliable repairer. The vehicle will become extremely
unstable during br aking, and the ABS
system may fail, which could cause an accident resulting in death or seri-
ous injury.
■When the electric power steer-
ing 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 pre-
cautions. 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.

matic transmission) or R (manual
transmission).
 Stop the engine.
 Turn on the emergency flashers.
( P.326)
 Check the degree of the tire
damage.
A tire should only be repaired with
the emergency tire puncture repair
If you have a flat tire
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily with the emergency tire
puncture repair kit.

■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair. Driving with a
flat tire may cause a circumferential groove on the side wall. In such a
case, the tire may explode when
using the emergency tire puncture repair kit, resulting in death or serious
injury.
