Distance Alert
*
The Distance Alert 31
function can help the driver
become aware if the time interval to the vehicle in front is too short. However, the vehicle must be equipped with a head-up display in order to display the DistanceAlert, which will then be indicated by a symbolon the windshield as long as the time interval tothe vehicle ahead is shorter than the set timeinterval.
Distance Alert is active at speeds above 30 km/h (20 mph) and only reacts for vehicles ahead mov-ing in the same direction as your vehicle. No dis-tance information is provided for oncoming, slow-moving or stationary vehicles.
NOTE
• Distance Alert is only available in vehicles that can display information on the wind-shield with a head-up display.
• Distance Alert is deactivated while Adap-tive Cruise Control is active.

Alert35
The Distance Alert function can be set to differ- ent time intervals.
Different time intervals to the vehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, the longerthe time interval. One bar rep-resents an interval of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
The same symbol appears when the Adaptive Cruise Control function is activated.

NOTE
•The greater the vehicles' speed, the greater the distance between them for aset time interval.
• Only use the time intervals permitted bylocal traffic regulations.
• The set time interval is also used by theAdaptive Cruise Control and Pilot Assistfunctions.
WARNING
•Only use a time interval suitable for the current traffic conditions.
• The driver should be aware that shorttime intervals give them limited time toreact and act to any unforeseen trafficsituation.

Distance Alert limitations36
Distance Alert functionality may be reduced in certain situations.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 shorter

distance than the one that has been set or 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 37
) 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 38
.
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 there are 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 thebrakes 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.
