Speed limiter *
A speed limiter (Speed Limiter — SL) can be regarded as a reverse cruise control — thedriver regulates the speed using the acceleratorpedal but is prevented by the speed limiter fromaccidentally exceeding a pre-selected/presetmaximum speed.

WARNING
The Speed Limiter is an aid and cannot deal with all traffic, weather and road conditions. The driver must always pay attention to traffic conditions and take action when the SpeedLimiter is not maintaining a suitable speed. The driver always has the ultimate responsibil- ity for the car being driven safely and inaccordance with applicable traffic rules andregulations, even when the Speed Limiterfunction is in use.

standby mode
–Press the steering wheel button (2).
> The speed limit markings and symbols in the driver display change colour from WHITE to GREY — Cruise Control is nowtemporarily deactivated and the driver cantemporarily exceed the set speed.
Standby mode on driver intervention
The cruise control is temporarily deactivated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position
• the clutch pedal is held depressed for longerthan 1 minute
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
The driver must then control the speed himself/herself. A temporary increase in speed with the accelera- tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released.
Automatic standby mode
Cruise control is temporarily disengaged and set in standby mode if:
• wheels lose traction
• engine speed is too low/high
• brake temperature is too high
• speed falls below 30 km/h (20 mph).
The driver must then control the speed himself/herself.

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

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.

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.
