Driver support systems
The vehicle is equipped with a number of driver support systems that help provide the driver withactive/passive support.
Some of these systems are standard while others are optional and they are designed to e.g., helpthe driver maintain a set speed or a set distanceto a vehicle ahead, or warn the driver of a poten-tial collision situation and in certain cases applythe brakes if necessary. Certain optional systemscan also assist in various parking situations.

DRIVER SUPPORT
270vehicle set by the driver. If the radar sensor does not 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 such aswhen there are great differences in speedbetween vehicles, or if the vehicle ahead brakessuddenly. Due to limitations in the radar sensor,braking may occur unexpectedly or not at all. Adaptive Cruise Control can follow another vehi- cle from a standstill up to 125 mph (200 km/h).Always observe posted speed limits. The driver can also toggle between ACC and Cruise Control (CC) – see the article "Switchingbetween Cruise Control and Adaptive CruiseControl".
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 samelane) 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
Adaptive Cruise Control only warns of vehicles detected by the radar sensor. In some casesthere may be no warning or the warning maybe delayed. The driver should always apply thebrakes when necessary.
Head-up-display *
A flashing light alerts the driver
A flashing icon will appear in the head-up display to alert the driver of a collision risk.
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.

WARNING
When ACC is in standby mode, the driver has to control the vehicle's speed and distance toa vehicle ahead. When ACC is in standby mode, the driver will be alerted if the distance to the vehicle aheadis too short by the Distance Alert function.See the article "Distance Alert" for additionalinformation.
Standby mode due to action by the driver
ACC 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 setspeed for more than 1 minute.
In these cases, the driver will have to regulate thevehicle's speed. A temporary increase in speed, such as when passing another vehicle, does not affect the ACCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.
Automatic standby mode
ACC interacts with other systems, such as Electronic Stability Control. If any of these othersystems are not functioning properly, ACC willturn off automatically.
WARNING
If this happens, the driver will be alerted by an audible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
ACC switches automatically to standby mode if: • the vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determineif the vehicle ahead is stationary or is anobject such as a speed bump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow
• the driver opens the door
• the driver unbuckles the seat belt
• the engine speed (rpm) is too high/low
• the wheels lose traction
• the brake temperature is too high
• the parking brake is applied
• the stability system's
ESC Sport Mode is
activated
• the
Off Road drive mode is selected
• The radar sensor is covered by e.g., wet snow or if heavy rain interferes with radar waves
Reactivating ACC from standby mode
Generic illustration
To reactivate ACC after it has temporarily been put in standby mode:
–Press the button (1).
> 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.

Adaptive Cruise Control (ACC) - limitations
Adaptive Cruise Control (ACC) functionality may be limited in certain situations.
Steep roads and/or heavy loadsAdaptive Cruise Control is primarily intended for use on relatively level roads. The function may notbe able to maintain the correct time interval tothe vehicle ahead when driving down steep hills.The driver should be attentive and prepared toapply the brakes in these situations. Do not use Adaptive Cruise Control when the vehicle is transporting a heavy load or if it is tow-ing a trailer.
Additional information
• The Off Road drive mode cannot be
selected if Adaptive Cruise Control is acti- vated.
• Adaptive Cruise Control uses the vehicle'scamera and radar sensor, which have certaingeneral limitations. See the articles "Cameralimitations" and "Radar sensor limitations"for additional information.
