WARNING
•The radar sensor has a limited field of vision. In some situations, it may detect avehicle later than expected or not detectother vehicles at all.
• The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
• The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
• Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
• Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see. Poorweather or winding roads can affect theradar sensor's capacity to detect vehiclesahead.
• A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorterdistance than the one that has been setor not illuminating at all.
•High speeds may also result in the warn- ing light illuminating at a shorter distancethan the one that has been set due tolimitations in the radar sensor's range.
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

Adaptive Cruise Control *
Adaptive Cruise Control (ACC 41
) helps the
driver maintain a constant speed with a set time interval to the vehicle ahead.
Adaptive Cruise Control helps provide a more relaxed driving experience on long trips on high-ways or long, straight roads with even trafficflows.
The camera/radar sensor measures the distance to the vehicle ahead 42
.
The driver sets a speed and a time interval to the vehicle ahead. If the camera/radar sensor detects a slower-moving vehicle ahead, your vehicle's speed will be automatically adapted according to the set time interval to that vehicle. When thereare no longer slower-moving vehicles ahead, thevehicle will return to the set speed.

WARNING
•The Adaptive Cruise Control function is supplementary driver support intended tofacilitate driving and help make it safer –it cannot handle all situations in all traffic,weather and road conditions.
• The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
• Adaptive Cruise Control is not a substi-tute for the driver's attention and judg-ment. The driver is always responsible forensuring the vehicle is driven in a safemanner, at the appropriate speed, with anappropriate distance to other vehicles,and in accordance with current trafficrules and regulations.
NOTE
Depending on market, this function may be either Standard or Optional.
Adaptive Cruise Control regulates speed by accelerating and braking. It is normal for the brakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts to regu- late speed smoothly. The driver must apply thebrakes in situations requiring immediate braking.For example, 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 is designed to follow a vehicle ahead in the same lane and maintain atime interval to that vehicle set by the driver. If theradar sensor does not detect a vehicle ahead, itwill instead maintain the speed set by the driver.This will also happen if the speed of the vehicleahead exceeds the set speed for your vehicle.
• Adaptive Cruise Control can follow anothervehicle at speeds from a standstill up to200 km/h (125 mph).
WARNING
• Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible and must intervene if the sys-tem fails to detect a vehicle ahead.
• Adaptive Cruise Control does not brakefor people or animals and does not brakefor small vehicles, such as bikes andmotorcycles. Similarly, it does not brakefor low trailers, oncoming, slow-moving orstationary vehicles and objects.
• Do not use Adaptive Cruise Control indemanding situations, such as in city traf-fic, at intersections, on slippery surfaces,with a lot of water or slush on the road, inheavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
CAUTION
Maintenance of Adaptive Cruise Control com- ponents may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.

Adaptive Cruise Control andcollision warning

.
Adaptive Cruise Control utilizes approx. 40% of the vehicle's braking capacity. If a situationrequires more braking force than the AdaptiveCruise Control can provide, and if the driver doesnot apply the brakes, a warning light and audiblewarning signal will be activated to alert the driverthat immediate action is required.
NOTE
Visual warnings on the windshield may be dif- ficult to notice in cases of strong sunlight,reflections, extreme light contrasts, or if thedriver is wearing sunglasses or is not lookingstraight ahead.
WARNING
Adaptive Cruise Control only issues a warning for vehicles detected by its radar unit – thus, awarning may come after a delay or not at all.
• Never wait for a warning. Apply the brakes when necessary.
