High Engine Coolant Temperature Warning LightThe light flashes when the engine coolant temperature is
extremely high, and illuminates when the engine coolant
temperature increases further.
Handling Procedure:
Flashing light
Drive slowly to reduce engine load until you can find a
safe place to stop the vehicle and wait for the engine to
cool down.
Illuminated light This indicates the possibility of overheating. Park the vehi-
cle in a safe place immediately and stop the engine.
Refer to Overheating P. 502.
Do not drive the vehicle with the high engine coolant tem-
perature warning light illuminated. Otherwise, it could
result in damage to the engine.
Power Steering Malfunction Indicator Light
The light illuminates/flashes if the electric power steering
has a malfunction.
If the light illuminates/flashes, stop the vehicle in a safe
place and do not operate the steering wheel. There is no
problem if the light turns off after a while. Contact your
Toyota dealer if the light illuminates/flashes continuously.
• If the indicator light illuminates/flashes, the power steer-ing will not operate normally. If this happens, the steer-
ing wheel can still be operated, however, the operation
may feel heavy compared to normal, or the steering
wheel could vibrate when turning.
• Repeatedly jerking the steering wheel left and right while the vehicle is stopped or moving extremely slowly will
cause the power steering system to go into protective
mode which will make the steering feel heavy, but this
does not indicate a problem. If this occurs, park the vehi-
cle safely and wait several minutes for the system to
return to normal.

If Trouble Arises
WARNING
■Never tamper with the air bag/pretensioner systems and always have
your Toyota dealer perform all servicing and repairs:
Self-servicing or tampering with the systems is dangerous. An air bag/pre-
tensioner could accidentally activate or become disabled causing serious
injury or death.
■
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, decrease
vehicle speed immediately and avoid sudden maneuvering and
braking:
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, it is danger-
ous to drive the vehicle at high speeds, or perform sudden maneuvering
or braking. Vehicle drivability could worsen and result in an accident.
To determine if you have a slow leak or a flat, pull over to a safe position
where you can check the visual condition of the tire and determine if you
have enough air to proceed to a place where air may be added and the
system monitored again by your Toyota dealer or a tire repair station.
■Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is dangerous, even if you know why it
is illuminated. Have the problem taken care of as soon as possible
before it develops into a more serious situation that could lead to tire
failure and a dangerous accident.
