Parking climate
Parking climate is an umbrella term for variousfunctions that improve the passenger compart-ment climate when the vehicle is parked, e.g.preconditioning.
Parking climate functions are controlled from theParking climate tab in the center display's Climate view.

Preconditioning
Preconditioning the vehicle before driving canhelp reduce wear and reduce energy consump-tion during a trip.
Preconditioning can be started immediately orstarted at a preset time using a timer.
The function utilizes several of the vehicle's sys-tems:
In cold weather, the parking heater heats thepassenger compartment to a comfortabletemperature.
In warm weather, air conditioning cools thepassenger compartment to a comfortabletemperature.
The electrically heated steering wheel* andseats* can be activated.
Heating for the windshield, rear window anddoor mirrors are automatically activated asneeded.
During preconditioning in a hot climate, conden-sation from the air conditions may drip under thevehicle. This is normal.

NOTE
Preconditioning is only available when the caris connected to an electrical outlet. A charg-ing post that is not always active, for examplebecause of a timer, can cause loss of functionfor preconditioning.
If the car is not connected to an electricalsocket it is still possible in a warm climate toachieve brief cooling of the passenger com-partment by direct starting preconditioning.

NOTE
During preconditioning of the passengercompartment, the vehicle works to reach acomfortable temperature and not the tem-perature set in the climate system.

KEY, LOCKS AND ALARM
* Option/accessory.242
Remote key range
In order to function correctly, the remote keymust be within a certain distance from the vehi-cle.

Manual use
The remote key's functions for e.g. locking and
unlocking, which are activated by pressing or
, have a range of approx. 20 meters (65 feet)from the vehicle.
If the vehicle's locks do not react, move closerand try again.

Keyless use 8
The shaded areas around the vehicle illustrate the rangeof the system's antennas.
For keyless use, a remote key or the Key Tagmust 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 canbe 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 thevehicle while the engine is running, thewarning message Vehicle key notfound Removed from vehicle will bedisplayed in the instrument panel and an audiblesignal will sound when the last door is closed.
The message will disappear when the key isreturned to the vehicle and the O button on theright-side steering wheel keypad is pressed orwhen the last door is closed again.

DRIVER SUPPORT
* Option/accessory.270
Driver support systems
The vehicle is equipped with a number of driversupport systems that can provide the driver withactive or passive assistance in various situations.
The systems can, for example, help the driver:
maintain a set speed
maintain a set time interval to the vehicleahead
help prevent a collision by warning the driverand applying the brakes
park the vehicle.
Some of the systems are standard and others areoptions. This also varies from market to market.

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.

WARNING
While the power steering is working atreduced power, the driver support functionsand systems with steering assistance are notavailable.
In such a situation, the driver display showsthe Power steering failure message, com-bined with a STEERING WHEEL symbol.

Electronic Stability Control
The Electronic Stability Control (ESC1) functionhelps the driver avoid skidding and improves thevehicle's directional stability.
This symbol will be displayed inthe instrument panel when theESC system is intervening.
When the ESC has intervenedto apply the brakes, a pulsingsound may be heard and thevehicle may accelerate more slowly than expec-ted when the accelerator pedal is depressed.
The ESC system consists of the following sub-functions:
Stability control2
Spin control and active yaw control
Engine drag control
WARNING
The Electronic Stability Control systemESC 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 2
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.
1Electronic Stability Control2Also called traction control.

Temporarily deactivating using the
accelerator pedal
The set maximum speed can be temporarilydeactivated and exceeded using the acceleratorpedal without first putting the Speed Limiter instandby mode, e.g. when quick acceleration isrequired.
To do so:
1. Depress the accelerator as far as possibleand then release it when the desired speedhas been reached.
> The Speed Limiter will remain activatedand the symbol in the instrument panelwill be WHITE.
2. Release the accelerator pedal fully when thetemporary acceleration is completed.
