DRIVER SUPPORT
* Option/accessory.

Driver support systems
The vehicle is equipped with a number of driver support systems that can provide the driver withactive or passive assistance in various situations.
The system can, for example, help the driver maintain a set speed or a set time interval to thevehicle ahead, help prevent a collision by warningthe driver and applying the brakes, or assist thedriver while parking. Some of the systems are standard and others are options. This also varies from market to market.

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.

DRIVER SUPPORT
* Option/accessory.263
WARNING
While the power steering is working at reduced power, the driver support functionswith steering assistance are not available. In such a situation, the driver display shows the
Power steering failure or Power
Steering Assist Temporarily Reduced
message, combined with a STEERING WHEEL symbol.
Changing the level of steering wheel resistance *
To change the level of steering wheel resistance, see the description of the INDIVIDUAL optionunder "Available drive modes" in the "Drivemodes" section. On models not equipped with drive mode con- trols and the INDIVIDUAL option, steering wheelresistance can instead be set in the center dis-play's Top view under:

Stability system Roll StabilityControl
The Roll Stability Control (RSC 1
) system helps
minimize the risk of a rollover in the event of e.g. a sudden evasive maneuver or if the vehiclebegins to skid.
The RSC system monitors the lateral angle at which the vehicle is leaning and registers anychanges. Using this information, the system cal-culates the likelihood of a rollover. If there is animminent risk of a rollover, Electronic StabilityControl is activated, engine torque is reduced andbrakes are applied to one or more of the wheelsuntil the vehicle has regained stability.

Electronic Stability ControlThe Electronic Stability Control (ESC 2
) function
helps the driver avoid skidding and improves the vehicle's directional stability.
This symbol will be displayed in the instrument panel when theESC system is intervening. When the ESC has intervened to apply the brakes, a pulsingsound may be heard and the
vehicle may accelerate more slowly than expec-ted when the accelerator pedal is depressed.
The ESC system consists of the following sub- functions: • Stability control 3
• Spin control and active yaw control
• Engine drag control
WARNING
• The Electronic Stability Control system ESC is supplementary driver supportintended to facilitate driving and make itsafer – it cannot handle all situations inall traffic, weather and road conditions.
• ESC is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
Stability control 3This function helps control the driving and brak-ing force of each individual wheel in an attemptto stabilize the vehicle.
Spin control and active yaw controlThis 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 from spinning while the vehicle is accelerating.
Engine drag control
Engine drag control (EDC
4
) helps prevent inad-
vertent wheel lock, e.g. after downshifting orusing engine braking when driving at low speedson a slippery surface. Inadvertent wheel lock while driving could impair the driver's ability to steer the vehicle.
