Speed-dependent steering wheelresistance
Speed-dependent power steering increases the steering wheel resistance in pace with the vehi-cle's speed to give the driver an enhanced feel-ing of control and stability.
Steering may feel stiffer on highways. When parking and at low speeds, it will be easier tomove the steering wheel.
NOTE
In some situations, the power steering may become too hot and require temporary cool-ing – during such time the power steering willwork at reduced output and the steeringwheel may feel more difficult to move. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.
