Steering system information  
The power steering system is not hydraulic, it is electro-mechanical.  
In both cases, the power steering works only when the engine is run-  
ning.  
The hydraulic power steering system uses hydraulic lines, hydraulic  
oil, a pump, a filter, and other parts to maintain a constant oil pres-  
sure in the hydraulic system.  
The electro-mechanical power steering system automatically adjusts  
to driving speed, steering torque, and the steering angle of the  
wheels. It delivers extra steering force only when you are actually  
turning the wheels. The electro-mechanical power steering works only  
when the engine is running.

WARNING  
Turning the steering wheel is very hard when the power steer-  
ing system is not working. This makes it harder to steer and  
control the vehicle.  
Power steering works only when the engine is running.  
Never let the vehicle coast with the engine switched off.  
Never remove the key from the ignition switch while the vehi-  
cle is moving or rolling to a stop. The steering wheel will lock  
and you will be unable to control the vehicle.
