The seats can be ventilated to provide increased comfort in warm weather.
The ventilation system consists of fans in the seats and backrest that draw air through the seatupholstery. The cooler the passenger compart-ment is, the greater the cooling effect of the ven-tilation. The system can be activated when theengine is running.

KEY, LOCKS AND ALARM
* Option/accessory.
234 For keyless use, a remote key or the Key Tag must be within the shaded areas shown in theillustration, i.e. a semicircle with a radius ofapprox. 1.5 meter (5 feet) along the sides of thevehicle or approx. 1 meter (3 feet) from the trunklid.
NOTE
The functions of the remote control key can be disrupted by ambient radio waves, build-ings, topographical conditions, etc. The vehi-cle can always be locked/unlocked using thekey blade.
If the remote key is removed from the vehicle
If the remote key is removed from the vehicle while the engine is running, the warning message
Vehicle key not
found Removed from vehicle will be
displayed in the instrument panel and an audible signal will sound when the last door is closed.

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.
