■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

cates 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.

to depress the brake pedal more strongly than normal to stop the vehicle.

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 illu-
minated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock more quickly in
an emergency stop than under normal circumstances.

nated because the engine could stop unexpectedly.
