6-3. Do-it-yourself maintenance
Maintenance and care
Use only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
When rotating, repairing or
changing your tires, check that
the wheel nuts are still tight after
driving 1600 km (1000 miles).
Be careful not to damage the
aluminum wheels when using
tire chains.
Use only Toyota genuine balance
weights or equivalent and a plas-
tic or rubber hammer when bal-
ancing your wheels.
WARNING
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight-ened, leading to bolt or disc wheel
damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off,
causing an accident and resulting in death or serious injury. Remove any oil or grease from the wheel bolts or
wheel nuts.
■Use of defective wheels prohib-
ited
Do not use cracked or deformed wheels. Doing so could cause the tire
to leak air during driving, possibly causing an accident.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement
may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer. In addition, make sure to
purchase your tire pressure warn- ing valves and transmitters at any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
●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.

When trouble arises
■Brake hold operated indicator
■Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location or
audio sound.
■Front passenger detection sensor, seat belt reminder and warning buzzer
●If luggage is placed on the front pas-senger seat, the front passenger
detection sensor may cause the warn- ing light to flash and the warning 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
For some models, the malfunction indi- cator lamp will come on if the fuel tank
becomes completely empty. If the fuel tank is empty, refuel the vehicle immedi-ately. The malfunction 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 12-volt battery charge becomes insufficient or the voltage tem-
porarily drops, the electric power steer- ing system warning light may come on and the warning buzzer may sound.
■When the tire pressure warning light comes on
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P.386, 397
If none of the tires are punctured:
Turn the power switch off then turn it to ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks for approximately 1 minute then stays on

1 After the temperature of the tires has lowered sufficiently, check the infla-
tion pressure of each tire and adjust them to the specified level.
2 If the warning light does not turn off even after several minutes have
elapsed, check that the inflation pressure of each tire is at the speci-fied level and perform initialization.
( P.337)
■The tire pressure warning light may come on due to natural causes

■When a tire is replaced with a spare
tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and trans- mitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few min-utes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat, the
tire pressure warning light will not turn off even though the flat tire has been replaced with the spare tire. Replace the
spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure warning light will go off after a
few minutes.
■Conditions that the tire pressure warning system may not function properly
P. 3 3 6
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. The vehicle will become extremely unstable during braking, 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
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 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.
●Vehicles with a compact spare tire and full-size 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 any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Vehicles with emergency tire punc-ture 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.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
