CAUTION
■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
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.
●Vehicles with standard tires:
• 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 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 Toyota dealer.
• Avoid abrupt maneuvering and brak ing. If the vehicle tires deterio-
rate, you could lose control of th e steering wheel or the brakes.
●Vehicles with run-flat tires:
• Decelerate to the lowest appropr iate speed as soon as possible.
Do not drive over 50 mph (80 km/h).
• Check and adjust the tire inflation 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. Have
the tire replaced by the nearest Toyota dealer.
• Avoid abrupt maneuvering and brak ing. If the vehicle tires deterio-
rate, you could lose control of th e steering wheel or the brakes.
