Toyota Yaris: If a Warning Light Turns On or Flashes / Stop Vehicle in Safe Place Immediately
If any of the following warning lights turns on, the system may have a
malfunction. Stop the vehicle in a safe place immediately and contact
your Toyota dealer.
Power Steering Malfunction Indicator Light
- If the indicator light illuminates/flashes, the power steering will not
operate
normally. If this happens, the steering 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 vehicle safely and
wait
several minutes for the system to return to normal.
WARNING
Do not drive with the brake system warning light illuminated.
Contact
your Toyota dealer to have the brakes inspected as soon as possible
Driving with the brake system warning light illuminated is dangerous.
It indicates that your brakes may not work at all or that they could completely
fail
at any time. If this light remains illuminated, after checking that the parking
brake is fully released, have the brakes inspected immediately.
In addition, the effectiveness of the braking may diminish so you may
need
to depress the brake pedal more strongly than normal to stop the vehicle.
Do not drive with both the ABS warning light and brake warning light
illuminated. Have the vehicle towed to your Toyota dealer to have the
brakes inspected as soon as possible
Driving when the brake system warning light and ABS warning light are
illuminated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock more
quickly in
an emergency stop than under normal circumstances.
NOTICE
Charging System Warning Light
Do not continue driving when the charging system warning light is
illuminated because the engine could stop unexpectedly.
Engine Oil Warning Light
- Do not run the engine if the oil pressure is low. Otherwise, it
could result in
extensive engine damage.
- Do not run the engine if the oil level is low. Otherwise, it could
result in
extensive engine damage.
High Engine Coolant Temperature Warning Light
Do not drive the vehicle with the high engine coolant temperature
warning
light illuminated. Otherwise, it could result in damage to the engine.
If any warning light turns on/flashes, take appropriate action for
each light. There is no problem if the light turns off, however if
the light does not turn off or turns on/flashes again, consult your
Toyota dealer...
