Distance Warning *
The Distance Warning function (Distance Alert) warns the driver if the time interval to the vehicleahead becomes too short.
Distance warning is active at speeds
above 30 km/h (20 mph) and only reacts to thevehicle ahead travelling in the same direction. Nodistance information is provided for oncoming,slow or stationary vehicles.
NOTE
Distance warning is deactivated during the time the adaptive cruise control is active.
WARNING
Distance warning only reacts if the distance to the vehicle ahead is shorter than the presetvalue - the speed of the driver's vehicle is notaffected.

In cars equipped with head-up display, a symbol is shown on the windscreen for as long as thetime interval to the vehicle ahead is shorter thanthe preset value. However, this presupposes that the

via settings in the car's menu system; see the heading "Head-up display" for how this works.

Information on the windscreen may be diffi- cult to see in strong sunlight and when wear-ing sunglasses.

Activating and setting the time interval for Distance warning *
The Distance warning (Distance Alert) function can be activated/deactivated and a time intervalcan be set.

warning
The function is activated/deac- tivated in function view in thecentre display.
–Tap on the Distance Alert button in func-
tion view.
> Distance warning is activated/deactivated, a green/grey indicator is displayed in the button.
Setting the time interval for Distance warning
Different time intervals to the vehicle in front can be selectedand shown in the driver displayas 1-5 horizontal lines - themore lines the longer the timeinterval. One line representsabout 1 second to the vehicle
in front, 5 lines represents about 3 seconds.
The same symbol is also shown when the adap- tive cruise control function is activated.
Control for time interval.

–Press the steering wheel button (1) or (2) to increase or decrease the time interval.
> The distance indicator (3) shows the cur- rent time interval.
NOTE
The higher the speed the longer the calcula- ted distance in metres for a given time inter-val. The set time interval is also used by the Adaptive Cruise Control function. Only use the time intervals permitted by local traffic regulations.

Limitations of Distance Warning *
The Distance warning (Distance Alert) function may have limitations in certain situations.
NOTE
Strong sunlight, reflections or strong varia- tions in light intensity, as well as wearing sun-glasses, could mean that the warning light inthe windscreen cannot be seen. Poor weather or winding roads could affect the radar unit's capacity to detect vehicles infront. The size of other vehicles could also affect detection capacity, e.g. motorcycles. Thiscould mean that the warning lamp illuminatesat a shorter distance than the setting or thatthe warning is temporarily absent. Extremely high speeds can also cause the lamp to illuminate at a shorter distance thanthat set due to limitations in sensor range.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Adaptive cruise control
*
The adaptive cruise control (Adaptive Cruise Control - ACC) helps the driver to maintain aneven speed combined with a pre-selected timeinterval to the vehicle ahead.
An adaptive cruise control provides a more relax- ing driving experience on long journeys on motor-ways and long straight main roads in smooth traf-fic flows.
The camera and radar unit measures the distance to the vehicle ahead 5
.
The driver selects the desired speed and a time interval to the vehicle ahead. If the camera andradar unit detects a slower vehicle in front of thecar, the speed is adapted automatically via thepreset time interval to the vehicle. When the road

is clear again the car returns to the selected speed.
WARNING
The Adaptive cruise control is an aid, which cannot handle all traffic, weather and roadconditions. The driver must always be observant with regard to the prevailing traffic conditions andintervene if the Adaptive cruise control doesnot maintain a suitable speed or suitable timeinterval. Read all the sections about the adaptive cruise control in the owner's manual in orderto learn about its limitations, of which thedriver should be aware before the function isused. The driver always bears responsibility for maintaining the correct time interval andspeed - even when the Adaptive cruise con-trol is being used.
Adaptive cruise control regulates the speed with acceleration and braking. It is normal for thebrakes to emit a low sound when they are beingused to adjust the speed. The adaptive cruise control aims to control the speed in a smooth way. In situations that demandsudden braking the driver must brake himself/herself. This applies in case of large speed differ- ences or if the vehicle in front brakes suddenly.Due to the limitations of the radar unit, brakingmay come unexpectedly or not at all. The adaptive cruise control aims to follow the vehicle ahead in the same lane at a time intervalset by the driver. If the radar unit cannot see anyvehicle in front then the car will instead maintainthe speed set and stored by the driver. This alsotakes place if the speed of the vehicle aheadincreases and exceeds the stored speed. The following applies for cars with automatic gearbox:
• Adaptive cruise control can follow anothervehicle at speed from 0 km/h up to200 km/h (125 mph).
The following applies for cars with manual gear-box: • The Adaptive cruise control can follow another vehicle at speeds from 30 km/h(20 mph) up to 200 km/h (125 mph).
WARNING
Adaptive cruise control is not a collision avoid- ance system. The driver must intervene if thesystem does not detect a vehicle in front. The adaptive cruise control does not brake for humans or animals, and not for small vehiclessuch as bicycles and motorcycles. Nor for lowtrailers, oncoming, slow or stationary vehiclesand objects. Do not use the Adaptive cruise control, for example, in city traffic, at junctions, on slipperysurfaces, with a lot of water or slush on theroad, in heavy rain/snow, in poor visibility, onwinding roads or on slip roads.
IMPORTANT
Maintenance of adaptive cruise control com- ponents must only be performed at a work-shop - an authorised Volvo workshop is rec-ommended.

WARNING
The adaptive cruise control only warns of vehicles which its radar unit has detected -hence a warning may not be given, or it maybe given with a certain delay. Do not wait for awarning without braking when so required.

Activating and starting the adaptive cruise control *
The adaptive cruise control (Adaptive Cruise Control - ACC) must first be activated and thenstarted if it is to control the speed and distance.
NOTE: The illustration is schematic - details may vary depending on car model.
Activate Adaptive Cruise ControlImmediately after the engine is started the Adap- tive Cruise Control is in the standby mode.
–Press ◀ (2) or ▶ (3) to browse to the sym-
bol/function
(4).
> The symbol is displayed and Adaptive Cruise Control is set in standby mode.
Start Adaptive Cruise ControlIn order to start the ACC the following require- ments apply:
• The driver's seatbelt must be buckled andthe driver's door must be closed.
• There must be a vehicle (the "target vehicle")within reasonable distance in front of the car,or the current speed must be at least15 km/h (9 mph).
• For cars with manual gearbox. Speed mustbe at the lowest 30 km/h (20 mph).
–With the symbol/function displayed -
press the steering wheel button
(1).
> Adaptive cruise control starts and the cur- rent speed is stored, which is shown in figures in the centre of the speedometer.
The time interval is onlyadjusted to the vehicle aheadby the ACC when the distancesymbol shows two vehicles.
At the same time a speed range is marked. The higher speed is the stored/selected speed and thelower speed is that of the vehi-cle ahead (target vehicle).
