Speed-dependent steering wheelresistance
Speed-dependent power steering increases thesteering 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. Whenparking and at low speeds, it will be easier tomove the steering wheel.
NOTE
In some situations, the power steering maybecome 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.

This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.

Spin control and active yaw control
This function is active at low speeds and brakesthe wheels that are spinning to transfer additionalpower from wheels that are not spinning.
This function also helps prevent the wheels fromspinning while the vehicle is accelerating.
