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.

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.

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.

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.

The driver is responsible for ensuring that the 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.
• 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.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be driven onflat roads. The function may not be able to main-tain the correct time interval to the vehicle aheadwhen driving down steep hills. The driver should be extra attentive and prepared to apply thebrakes.
• Do not use Pilot Assist if the vehicle is carry-ing a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to thevehicle electrical system.
Other limitations
•
The Off Road drive mode cannot be
selected when Pilot Assist is activated.

CauseAction
Water or snow is spraying/swirling up and blocking the radar signals or the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the cam-era/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radarsensor. Consult a workshop to have the area of the windshield on the inside of the cam-era's casing cleaned. An authorized Volvo workshop is recommended.
NOTE
Keep the windshield in front of the camera and radar unit clean.
Vehicle speedThe radar sensor's ability to detect a vehicle ahead is significantly reduced if:
• the speed of the vehicle ahead differs greatlyfrom your vehicle's speed
Limited field of visionThe radar sensor has a limited field of vision. Insome situations, it may detect a vehicle later thanexpected or not at all.
The radar sensor's field of vision.
The radar sensor's detection of vehicles very close to your vehicle may be delayed in cer-tain situations, e.g. if a vehicle pulls in between your vehicle and the vehicle directlyahead.
Small vehicles, such as motorcycles, or vehi- cles that are not driving in the center of thelane may remain undetected.
In curves, the radar may detect the wrong vehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow.
Low trailers may also be difficult or even impossi- ble for the radar to detect. The driver should beextra alert when driving behind vehicles towing low trailers when Adaptive Cruise Control or Pilot Assist is activated.
