Automatically activating anddeactivating the heated rear windowand door mirrors
The heated rear window and door mirrors areused to quickly remove condensation and icefrom the glass.
It is possible to select whether rear window anddoor mirror heating should be automatically acti-vated or deactivated when the engine is started.With automatic start activated, heating will beactivated when there is a risk of ice or condensa-tion on the windows or mirrors. Heating is auto-matically switched off when the window or doormirror is sufficiently warm and the condensationor ice is gone.
1.Tap Settings in the Top view in the centerdisplay.
2.Tap Climate.
3.Select Auto Rear Defroster to activate/deactivate automatic rear window and doorheating.

Setting the blower speed for thefront seats
The blower can be set to several different auto-matically controlled speeds for the front seat.
Blower control buttons in Climate view.
1. Open Climate view in the center display.
2.Tap the desired blower speed: Off, 1-5 orMax.
> The blower speed will be changed and thebuttons for the set speed will light up.

CAUTION
The air conditioning will not engage if theblower is turned off completely, which maycause fogging on the inside of the windows.
NOTE
The climate system automatically adapts air-flow as needed within the set blower speed,which means that airflow speed may varyslightly within the same blower speed.

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.

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer-tain situations.
Pilot Assist is a driver support function designedto simplify driving and assist the driver in manysituations. However, the driver is always responsi-ble for maintaining a suitable distance to vehiclesor objects around it and ensuring that the vehicleis correctly positioned in the traffic lane.

WARNING
In some situations, Pilot Assist may have trou-ble helping the driver properly or may bedeactivated automatically – we advise againstusing Pilot Assist in such cases. Examples ofsuch situations include:
the lane markings are worn, missing orcross each other.
lane division is unclear, for example, whenthe lanes divide or merge or at exits orwhen there are multiple sets of markings.
edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
the lane is narrow or winding.
the lane contains ridges or holes.
weather conditions are poor, e.g. rain,snow or fog or slush or reduced visibilitywith poor light conditions, backlighting,wet road surface, etc.
The driver should also note that Pilot Assisthas the following limitations:
High curbs, roadside barriers, temporaryobstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane mark-ings, with a subsequent risk of contactbetween the vehicle and such obstacles.
The driver is responsible for ensuring thatthe vehicle maintains a suitable distancefrom such obstacles.
The camera and radar sensors do nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects that completely or partiallyblock the route.
Pilot Assist does not "see" pedestrians,animals, etc.
The recommended steering input is lim-ited in force, which means that it cannotalways help the driver to steer and keepthe vehicle within the lane.
In vehicles equipped with SensusNavigation*, the function is able to useinformation from map data, which couldcause variations in performance.
Pilot Assist is switched off if the powersteering is working with reduced power -e.g. during cooling due to overheating(see section "Speed-dependent steeringforce").
The driver can always correct or adjust steeringassistance provided by Pilot Assist by turning thesteering wheel to the desired position.

Lane Keeping Aid limitations
In certain demanding driving conditions, LaneKeeping Aid may not be able to properly assistthe driver. In these situations, it is recommendedthat the function be deactivated.
Examples of such situations include:
road work
winter driving conditions
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane'sside markings
when the power steering works at reducedpower, e.g. during cooling due to overheating(see section “Speed-dependent steeringforce”).

NOTE
The function uses the vehicle's camera unit,which has some general limitations – see thesection "Camera unit limitations".

Limitations of Run-Off Mitigationwith steering assistance
In certain demanding driving conditions, thefunction may not be able to properly assist thedriver. In these situations, it is recommendedthat it is turned off.
Examples of such situations include:
road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane'sside markings
when the power steering works at reducedpower, e.g. during cooling due to overheating(see section “Speed-dependent steeringforce”).

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

Steering assistance during collisionrisks from oncoming traffic
This sub-function can help assist a distracteddriver who has not noticed that the vehicle isveering into oncoming traffic.
The function provides assistance by swerving your vehi-cle back into your own lane.
Oncoming vehicles
Own vehicle
The function is active at speeds between60-140 km/h (37-87 mph) on roads with clearlyvisible traffic lane markings/lines.
If your vehicle is starting to veer from your ownlane and a vehicle is approaching from the oppo-site direction, this function can help the driversteer the vehicle back into its own lane.
