Maintenance and care
■When replacing wheels
The wheels of your Toyota, except for the compact spare tire, are
equipped with tire pressure warning valves and transmitters that allow
the tire pressure warning system to provide advanced warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced,
the tire pressure warning valves and transmitters must be installed. (→P.
304)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing serious
injury or death.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.

358 5-2. Steps to take in an emergency
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with the tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire is replaced with the spare tire.
Replace the spare tire with the repaired tire and adjust the proper tire
inflation pressure. The tire pressure warning light will turn off after a few
minutes.
■If the tire pressure warning system is inoperative
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters are used.
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine Toyota wheels are used. (Even if you use Toyota
wheels, the tire pressure warning system may not work properly with
some types of tires.)
●If tire chains are used.

When trouble arises
359 5-2. Steps to take in an emergency
■If the tire pressure warning light comes on after blinking for 1 min-
ute frequently
If the tire pressure warning light comes on after blinking for 1 minute fre-
quently when the engine switch is turned to the “ON” position, have it
checked by your Toyota dealer.
■Customization that can be configured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features →P. 420) However, Toyota recommends that the
seat belt reminder buzzer be operational to alert the driver and front passen-
ger that the seat belts are not fastened.
CAUTION
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause 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.
●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 the tire is flat, change to 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.

368 5-2. Steps to take in an emergency
Installing the tire
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is
in motion, and the tire may
come off the vehicle.
Install the tire and loosely tighten each wheel nut by hand by
approximately the same amount.
Replacing a steel wheel with a compact spare tire
Tighten the nuts until the tapered
portion comes into loose contact
with the disc wheel sheet.
Replacing an aluminum wheel with a compact spare tire
Tighten the nuts until the tapered
portion comes into loose contact
with the disc wheel sheet.

When trouble arises
373 5-2. Steps to take in an emergency
CAUTION
■Replacing a flat tire
Observe the following precautions to reduce the risk of death or serious
injury:
●Never use oil or grease on the wheel bolts or wheel nuts.
The oil or grease can cause the wheel nuts to loosen, causing a seri-
ous accident.
Remove any oil or grease on the wheel bolts or wheel nuts.
●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.
Failure to follow these precautions could cause the nuts to loosen and
the wheel may fall off, which could lead to an accident causing death
or serious injury.
■When using the compact spare tire
●Remember that your compact spare tire is specifically designed for
use with your vehicle. Do not use your compact spare tire on another
vehicle.
●Do not use two compact spare tires simultaneously.
●Replace the compact spare tire with a standard tire as soon as possi-
ble.
●Avoid sudden acceleration, deceleration and braking, as well as sharp
cornering.
■Speed limit when using the compact spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failing
to observe this precaution may lead to an accident causing death or seri-
ous injury.

NOTICE
■Do not drive the vehicle with 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.
■Be careful when driving over bumps with the compact spare tire
installed on the vehicle
The vehicle becomes lower when driving with the compact spare tire
compared to when driving with standard tires. Be careful when driving
over uneven road surfaces.
■Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving
performance.
■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 correctly.
■To avoid damaging the tire pressure warning valves and transmit-
ters
Do not use liquid sealants on flat tires.
