Toyota Yaris: When Driving / Power Steering

Toyota Yaris XP210 (2020-2026) Owner's Manual / When Driving / Power Steering

Power steering is only operable when the engine is running. If the engine is off or if the power steering system is inoperable, you can still steer, but it requires more physical effort.
If the steering feels stiffer than usual during normal driving or the steering vibrates, consult your Toyota dealer.
The warning light notifies the driver of system abnormalities and operation conditions.
In addition, the buzzer may also activate depending on the system abnormality or operation condition.

Refer to Stop Vehicle in Safe Place Immediately. Refer to Power Steering Warning Buzzer.

NOTICE

Never hold the steering wheel to the extreme left or right for more than 5 seconds with the engine running. This could damage the power steering system.
