■Electric power steering system warning light (warning buzzer) 
When the 12-volt battery charge becomes insufficient or the voltage tempo- 
rarily drops, the electric power steering system warning light may come on 
and the warning buzzer may sound. 
■ 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 empt y, refuel the vehicle immediately. 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 repai rer, or any reliable repairer as soon 
as possible. 
■ When the tire pressure warning light comes on 
Inspect the appearance of the tire to check that the tire is not punctured. 
If the tire is punctured:  P. 478, 492 
If the tire is not punctured: 
Carry out the following procedure after the tire temperature has lowered suffi- 
ciently. 
● Check the tire inflation pressure and adjust to the appropriate level. 
● If the warning light does not go out even after several minutes, check that 
the tire inflation pressure is at the specified level and carry out initialization.
( P. 395) 
The warning light may come on again if the above operations are conducted 
without first allowing the tire temperature to lower sufficiently. 
■ The tire pressure warning light may come on due to natural causes 
The tire pressure warning light may turn on due to natural causes such as 
natural air leaks or  tire inflation pressure changes caused by temperature. In 
this case, adjusting the tire inflation pressure will turn off the warning light 
(after a few minutes). 
■ When a tire is replaced with a spare tire 
The compact spare tire is not equipped with a 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 has been replaced with the spare tire. Replace the 
spare tire with the repaired tire and adjus t the tire inflation pressure. The tire 
pressure warning light will go off after a few minutes.

WARNING
■If both the ABS and the brake system warning lights remain on 
Stop your vehicle in a safe place immediately and contact any authorized 
Toyota retailer or Toyota authorized r epairer, 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 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. 
● Stop your vehicle in a safe place as soon as possible. Adjust the tire infla- 
tion pressure immediately.  
● 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 any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer. 
● Vehicles with emergency tire puncture repair kit: If the tire pressure warn- 
ing light comes on even after tire inflat ion pressure adjustment, it is proba- 
ble that you have a flat tire. Check the tire s. 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. 
■ If a blowout or sudden air leakage should occur 
The tire pressure warning system may not activate immediately.
NOTICE
■ To ensure the tire pressure warning system operates properly 
Do not install tires with different specif ications or makers, as the tire pres- 
sure warning system may not operate properly.

When trouble arises
WARNING
■Replacing a flat tire 
● Do not touch the disc wheels or the area around the brakes immediately 
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. 
● 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 103 N•m 
(10.5 kgf•m, 76 ft•lbf) as soon as possible after changing wheels. 
• When installing a tire, only use wheel nuts that have been specifically
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 any authorized
Toyota retailer or Toyota authoriz ed repairer, or any reliable repairer. 
• When installing the wheel nuts, be sure to install the wheel nuts with the 
tapered ends facing inward. ( P. 412)
