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.
When steering wheel operations are heav ier than usually, 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 fl at, 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.
● Vehicles with emergency tire puncture re pair kit: If the tire pressure warn-
ing light comes on even after tire inflation pressure adjustment, it is proba-
ble 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.
■ 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 specifications or makers, as the tire pres-
sure warning system may not operate properly.
