Automatically activating anddeactivating the heated rear windowand door mirrorsThe heated rear window and door mirrors are used to quickly remove condensation and icefrom the glass.
It is possible to select whether rear window and door 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

Tap the desired blower speed:
Off, 1-5 orMax.
> The blower speed will be changed and the buttons for the set speed will light up.
CAUTION
The air conditioning will not engage if the blower 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.

Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated when the vehicle is at a standstill and Pilot Assistwill go into standby mode. This means that thebrakes will be released and the vehicle couldbegin to roll. The driver must actively apply thebrakes to keep the vehicle stationary. 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 Pilot Assist in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will be applied to keep the vehicle at a standstill. This occurs if Pilot Assist is keeping the vehicle stationary using the brakes and:
• the driver opens the door or unbuckleshis/her seat belt
• Pilot Assist has kept the vehicle at a stand-still for more than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer- tain situations.
Pilot Assist is a driver support function designed to 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 or cross 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 Assist has the following limitations: • High curbs, roadside barriers, temporary obstacles (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.

Camera limitations
The camera used by several of the driver support functions has certain limitations, which alsoaffect the functions using the camera.
Reduced visibilityThe camera has the same limitations as the human eye. In other words, its “vision" is impairedby adverse weather conditions such as heavysnowfall/rain, dense fog, swirling dust/snow, etc.These conditions may reduce the function of sys-tems that depend on the camera or cause thesesystems to temporarily stop functioning. Strong sunlight, reflections from the road surface, ice or snow covering the road, a dirty road sur- face, or unclear lane marker lines may drastically reduce the camera

CauseAction
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow. Clean the windshield in front of the camera/radar sensor and remove dirt, ice andsnow.
Thick fog, heavy rain or snow is blocking the radar signals or thecamera's range of visibility. No action. Heavy precipitation may sometimes prevent the camera/radar sensor fromfunctioning.
Water or snow is spraying/swirling up and blocking the radar signalsor the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the camera/radar sensor from functioning.
There is dirt between the inside of the windshield and the camera/radar sensor. Consult a workshop to have the area of the windshield on the inside of the camera'scasing cleaned. An authorized Volvo workshop is recommended.
Bright sunlight No action. The camera/radar sensor will reset automatically when lighting conditionsimprove.
NOTE
Keep the windshield in front of the camera and radar unit clean.
High temperaturesIf the temperature in the passenger compartment is very high, the camera/radar sensor will switchoff temporarily for approx. 15 minutes after theengine is started to protect its electronic compo-nents. When the temperature has cooled suffi-ciently, the camera/radar sensor will automati-cally restart.
Damaged windshield
CAUTION
If there are cracks, scratches or stone chips on the windshield in front of any of the cam-era and radar unit "windows" and this coversan area of about 0.5 × 3.0 mm(0.02 × 0.12 in.) or more, contact a workshopto have the windshield replaced – an author-ized Volvo workshop is recommended. Failure to take action could result in reduced performance for the driver support systemsthat use the camera and radar unit.
It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response. To avoid the risk of loss of function, malfunc- tion or reduced function of the driver supportsystems that use the radar unit, the followingalso apply:
• Volvo advises
against repairing cracks,
scratches or stone chips in the area infront of the camera and radar unit – theentire windshield should instead bereplaced.
• Before replacing the windshield, contactan authorized Volvo workshop to verify
