Camera limitations
The camera used by several of the driver support systems has certain limitations, which also affectthe systems using it.
Reduced visibility
WARNING
• The camera has the same limitations as the human eye. In other words, its “visionis impaired” by adverse weather condi-tions such as heavy snowfall, dense fog,etc. These conditions may reduce thefunction of systems that depend on thecamera or cause these systems to tem-porarily stop functioning.
• Strong sunlight, reflections from the roadsurface, ice or snow covering the road, adirty road surface, or unclear lane markerlines may drastically reduce the camera

Radar sensor limitations
The radar sensor used by several of the driver support systems has certain limitations, whichalso affect the systems using it.
Obstructions
The marked area must not be obstructed in any way. This area of the windshield should always be kept clean
The radar sensor is located at the upper, center section of the windshield along with the camera.
WARNING
Never place any objects, decals, etc., on the windshield in front of the camera/radar unit.This could reduce or block these components'functions, and could cause one or more of thesystems that utilize the them to stop function-ing.
If this symbol and the message
Windscreen Sensors blockedappear in the instrument panel, this indicates that the camera and/or radar
sensor cannot detect other vehicles ahead.
The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
CauseAction
The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow.Clean the windshield or remove the ice/ snow.
Thick fog or heavy rain/snow blocks reduces the camera/radar sensor's range of visibility.No action. The driver should be extra alert in conditions of this type.
Water or snow on the surface of the road swirl up and block radar signals or the camera's view.No action. The driver should be extra alert in conditions of this type.
There is dirt between the inside of the windshield and the camera/radar sensor.Have the area of the windshield cleaned by a trained and quali- fied Volvo service technician.

Deactivating/resuming Cruise Control (CC) Cruise Control (CC) can be temporarily deacti- vated and put in standby mode.
Deactivating and putting CC in standbymode
To temporarily deactivate and put Cruise Control in standby mode:
Function buttons and symbols
–Press the button (2).
> The set speed marker (4) and symbols will change colors from WHITE to GRAY. This indicates that CC is temporarily in standby mode and will not maintain a setspeed.
Standby mode due to action by the driver
CC is temporarily deactivated and put in standby mode if:
• the brakes are applied
• The gear selector is moved to
N
• the vehicle is driven faster than the set speed for more than 1 minute.
In these cases, the driver will have to regulate the vehicle's speed. A temporary increase in speed, such as when passing another vehicle, does not affect the CCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.
Automatic standby mode
CC switches automatically to standby mode if:
• the wheels lose traction
• engine speed (rpm) is too high/low
• brake temperature is too high
• the vehicle's speed goes below approx. 20 mph (30 km/h)
In these cases, the driver will have to regulate the vehicle's speed.
Reactivating CC from standby modeTo reactivate CC after it has temporarily been putin standby mode:
–Press the button (1).
> The set speed marker (4) will change color from GRAY to WHITE. The vehicle will then return to the most recently set
speed .
WARNING
There may be a significant increase in speed after the
button has been pressed.

Switching between Cruise Control (CC) and Adaptive Cruise Control (ACC)*
In models equipped with the optional ACC, the driver can toggle between CC and ACC.
Switching from ACC till CCA symbol in the instrument panel will indicate which system is currently being used:
CC
Cruise ControlACC
Adaptive Cruise Control
AA
A If the symbol is WHITE, the function is active. If the symbol is GRAY, the function is in standby mode.
To switch from ACC to CC
1. From the center display's Function view, tap
the
Activate cruise control button.
> The symbol in the instrument panel will
change from
(ACC) to (CC). This means that ACC has been com- pletely deactivated (turned off) and CC is instandby mode (ready for use but not cur-rently maintaining a set speed).
2. Press the
button on the left-side steer-
ing wheel keypad: CC goes into active mode and sets the vehicle's current speed.
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automatically
maintain a set distance to a vehicle ahead.
• Only the set speed will be maintained andthe driver will have to apply the brakeswhen needed.
If CC was activated when the engine was turned off, ACC will be selected and go into standbymode when the engine is restarted.
Switching from CC back to ACC1. In the center display's Function view, tap theActivate cruise control button.
> The symbol in the instrument panel will
change from
(CC) to (ACC). This means that CC has been com- pletely deactivated (turned off) and ACC is instandby mode (ready for use but not cur-rently maintaining a set speed/time interval).
2. Press the
button on the left-side steer-
ing wheel keypad: ACC goes into active mode and sets the vehicle's current speedand the selected distance to the vehicleahead.

Adaptive Cruise Control (ACC) *
ACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead.
The driver sets that desired speed and time inter- val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed. ACC is designed to follow a vehicle ahead in the same lane and maintain a time interval to thatvehicle set by the driver. If the radar sensor doesnot detect a vehicle ahead, ACC will insteadmaintain the speed set by the driver. ACC is designed to smoothly regulate speed. However, the driver must apply the brakes in sit-uations that require immediate braking. Thisapplies when there are great differences inspeed between vehicles, or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall. Adaptive Cruise Control can follow another vehi- cle from a standstill up to 125 mph (200 km/h).Always observe posted speed limits.
WARNING
• It is advisable to read through all of the related articles pertaining to ACC (seethe list at the end of this article).
• Adaptive Cruise Control cannot cover alldriving situations and traffic, weather androad conditions.
• This system is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance and speedand must intervene if Adaptive CruiseControl does not maintain a suitablespeed or suitable distance to the vehicleahead.
• Maintenance of ACC components mayonly be performed by a trained and quali-fied Volvo technician.
OverviewThe distance to the vehicle ahead (in the same lane) is monitored by a radar sensor. Your vehi-cle's speed is regulated by accelerating andbraking. The brakes may emit a sound when theyare being modulated by the adaptive cruise con-trol system. This is normal.
WARNING
•
Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible for applying the brakes if thesystem does not detect another vehicle.
• Adaptive Cruise Control does not react topeople or animals, or small vehicles suchas bicycles and motorcycles. It also doesnot react to slow moving, parked orapproaching vehicles, or stationaryobjects.
• Do not use Adaptive Cruise Control indemanding driving conditions such as citydriving or other heavy traffic situations, inslippery conditions, when there is a greatdeal of water or slush on the road, duringheavy rain or snow, in poor visibility, onwinding roads or on highway on- or off-ramps.
WARNING
The brake pedal moves when the adaptive cruise control system modulates the brakes.Do not rest your foot under the brake pedal.

Collision warning
Warning light
Adaptive Cruise Control can exert brake force that is equivalent to approximately 40% of thevehicle's total braking capacity. In situations requiring more brake force than ACC can provide and if the driver does not applythe brakes, an audible signal from the City Safetysystem will sound and warning light will illuminatein the windshield to alert the driver to react.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.
