Pinch protection for windows andsun curtains
All windows and sun curtains * that are controlled
electrically have a pinch protection function that is triggered if anything blocks them while theyare opening or closing.
If pinch protection is activated, movement will stop and then retract automatically to approx.50 mm (2 inches) from the point at which it wasblocked (or to full ventilation position). If pinch protection has been triggered, it is still possible to operate the window or sun curtainonce more in the same direction without pinchprotection, if this is done within 10 seconds afterpinch protection has been triggered. It is thus stillpossible to override pinch protection when clos-ing is interrupted (e.g. due to ice) by pressing andholding down the control until the window or suncurtain is fully closed.
WARNING
If the starter battery is disconnected, the func- tion for automatic opening and closing mustbe reset to function correctly. A reset isrequired in order for the pinch protection towork.
1 Does not apply to windshield and panoramic roof *, which are always laminated and therefore do not have this symbol.

Reset procedure for pinchprotection
If the power windows are not operating properly, you can try a reset procedure. The power sun curtains * also have a reset pro-
cedure that can be tested in case of problems.

Using the windshield and headlightwashers
The windshield and headlight washers clean the windshield and headlights. Use the right-sidesteering wheel lever to start the windshield andheadlight washers.
Starting the windshield and headlight washers
Washing function, right-hand steering wheel lever.
–Move the right-hand steering wheel lever toward the steering wheel to start the wind-shield and headlight washers.
> After the lever is released, the wipers make several extra sweeps.
CAUTION
Avoid activating the washer system when it is frozen or the fluid reservoir is empty. Other-wise, there is a risk of damaging the pump.
Headlight washer *To save washer fluid, the headlights are washed automatically according to a defined intervalwhen the headlights are on.
Reduced washingWhen there is about 1 liter (1 qt) of washer fluid left in the reservoir and the Washer fluid Level
low, refill message is displayed in the instrument
panel together with the
symbol, the washer
fluid supply to the headlights is cut off. This is to prioritize windshield cleaning and visibilitythrough it. The headlights are only washed if highor low beam is on.

Opening, closing and directing airvents Some of the air vents in the passenger compart- ment can be individually opened, closed anddirected.
Misting can be eliminated by directing the outer air vents towards the door windows. Direct the outer air vents into the passenger compartment to maintain a comfortable tempera-ture in warm weather.

DRIVER SUPPORT
* Option/accessory.293
Passing assistance with AdaptiveCruise Control Adaptive Cruise Control (ACC 47
) can assist the
driver when passing other vehicles.
How passing assistance worksWhen ACC is following another vehicle and you indicate that you intend to pass that vehicle by using the turn signal 48
, Adaptive Cruise Control
will begin accelerating toward the vehicle ahead before your vehicle has moved into the passing
lane. The function will then delay a speed reduction to avoid early braking as your vehicle approaches aslower-moving vehicle. The function remains active until your vehicle has passed the other vehicle.
WARNING
Please note that this function can be acti- vated in more situations than just passinganother vehicle, such as when a direction indi-cator is used to indicate a lane change orbefore exiting to another road – the vehiclewill then briefly accelerate.

Starting passing assistance withAdaptive Cruise Control
Requirements for passing assistanceIn order to activate passing assistance:
• your vehicle must be following a vehicle ahead (target vehicle)
• your vehicle's
current speed must be
at least 70 km/h (43 mph)
• the set speed
for ACC must be high
enough to safely pass another vehicle.
Starting parking assistanceTo start passing assistance:
–Turn on the left turn signal.
> Passing assistance will start.

Limitations of passing assistancewith Adaptive Cruise Control
Passing assistance functionality may be reduced in certain situations.
WARNING
The driver should be aware that if conditions suddenly change when using Parking Assis-tance, the function may implement an unde-sired acceleration in certain conditions. Some situations should be avoided, e.g. if: • the vehicle is approaching an exit in the same direction as passing would normallyoccur
• the vehicle ahead slows before your vehi-cle has had time to switch to the passinglane
• traffic in the passing lane slows down
• a vehicle for right-hand traffic is driven ina country with left-hand traffic (or viceversa).
Situations of this type can be avoided by tempo- rarily putting ACC 49
in standby mode.

NOTE
ACC can keep the vehicle stationary for no more than 5 minutes – after that time theparking brake is applied and Adaptive CruiseControl is deactivated. The parking brake must be released before Adaptive Cruise Control can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated when the vehicle is at a standstill and AdaptiveCruise Control will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehicle sta-tionary. This can occur if:
• the driver depresses the brake pedal
• the parking brake is applied
• the gear selector is moved to the
P
, N
or R
positions
• the driver puts Adaptive Cruise Control in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if Adaptive Cruise Control is keepingthe vehicle stationary using the brakes and:
• the driver opens the door or unbuckleshis/her seat belt
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.

Adaptive Cruise Control limitations
Adaptive Cruise Control (ACC 52
) may have lim-
ited functionality in certain situations.
Steep roads and/or heavy loadsAdaptive Cruise Control is primarily intended to be driven on flat roads. The function may not beable to maintain the correct time interval to thevehicle ahead when driving down steep hills. Thedriver should be extra attentive and prepared toapply the brakes.
• Do not use Adaptive Cruise Control if thevehicle is carrying a heavy load or towing atrailer.
Other limitations
•
The Off Road drive mode cannot be
selected if Adaptive Cruise Control is acti- vated.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

DRIVER SUPPORT
302When the vehicle is approaching an off-ramp or a fork in the road, the driver should steer towardthe desired lane to indicate to Pilot Assist thedesired direction of travel.
Pilot Assist strives to keep the vehicle
in the center of the lane
When Pilot Assist provides steering assistance, itstrives to position the vehicle in the center of thelane between the lane markings. For the smooth-est driving experience possible, the driver shouldpermit the vehicle to find the optimal positioning.The driver should check that the vehicle is posi-tioned safely in the lane and can always adjustthe vehicle's position by applying more force tothe steering wheel. If Pilot Assist does not position the vehicle appro- priately in the lane, the driver should turn off PilotAssist or switch to Adaptive Cruise Control.
