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 dealer or repairer, or another duly qualified and equipped profes-
sional. 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.
If the steering wheel becomes heavier than usual when operating, hold
firmly and operate using more force than usual.
■ If the tire pressure warning light comes on (vehicles with the tire pres-
sure warning system)
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.
● 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 dealer or repairer, or another duly qualified
and equipped professional.
● 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 (vehicles with the tire
pressure warning system)
The tire pressure warning system may not activate immediately.
NOTICE
■ To ensure the tire pressure warning system operates properly (vehi-
cles with the tire pressure warning system)
Do not install tires with different specif ications or makers, as the tire pres-
sure warning system may not operate properly.
