WARNING
The Speed Limiter function is supple-mentary driver support intended to facili-tate driving and help make it safer – itcannot handle all situations in all traffic,weather and road conditions.
The driver must always pay attention totraffic conditions and take action if theSpeed Limiter is not maintaining a suita-ble speed.
The Speed Limiter is not a substitute forthe driver's attention and judgment. Thedriver is always responsible for ensuringthe vehicle is driven in a safe manner, atthe appropriate speed, with an appropri-ate distance to other vehicles, and inaccordance with current traffic rules andregulations.

Changing Automatic Speed Limitertolerance
The Automatic Speed Limiter (ASL) can be setto different tolerance levels.
It is also possible to allow the vehicle to driveabove or below the posted speed limit. For exam-ple, if the vehicle is following a current postedspeed limit of 70 km/h (43 mph), the driver caninstead allow the vehicle to maintain a speed of75 km/h (47 mph).
Function buttons and symbols16.
–Tap the (1) button on the steeringwheel keypad until 70 km/h (43 mph) hasbeen changed to 75 km/h (47 mph) in thecenter of the speedometer (4).
> The vehicle will then use the selected tol-erance of 5 km/h (4 mph) as long as theposted speed limit the vehicle passes is70 km/h (43 mph).
This tolerance level will be followed untilthe vehicle passes a sign with a lower orhigher speed. The vehicle will then adjustto the new speed limit and the set toler-ance will be deleted from the system'smemory.
If Road Sign Information*17 is activated,the posted speed limit will also be indi-cated by a RED marking on the speedom-eter.
The set tolerance can be adjusted in the sameway as for the Speed Limiter's speed.

NOTE
The highest possible selectable tolerance is+/- 10 km/h (5 mph).

Automatic Speed Limiter limitations
Automatic Speed Limiter (ASL) utilizes the
speed limit information provided by the RSI18
function, not from the speed limit signs that thevehicle passes.
If RSI18 is unable to interpret and provide ASLwith speed information, ASL will go into standbymode and switch over to SL. The driver will thenhave to actively brake to bring the vehicle downto the appropriate speed.
ASL will be reactivated when RSI18 is once againable to interpret and provide speed information toASL.

Using engine braking instead of
applying the brakes
Cruise Control regulates speed by lightly applyingthe brakes. On downgrades, it can sometimes bedesirable to roll a bit faster and let speed bereduced instead by engine braking alone. Thedriver can temporarily disengage the Cruise Con-trol braking function.
To disengage CC:
–Press the accelerator pedal about halfwaydown and then release it.
> Cruise Control will automatically disen-gage the automatic brake function andspeed will only be reduced using theengine braking function.
How drive mode affects cruise control
The way the cruise control maintains the vehicle'sspeed can vary depending on the selected drive
mode22.

Cruise Control Eco Cruise with ECO drive
mode
In the ECO drive mode, cruise control's accelera-tion and deceleration will be smoother than inother drive modes to help provide optimal fuelefficiency and reduced environmental impact.Because of this, the vehicle's actual speed maybe slightly above or below the set speed.

Cruise Control Dynamic Cruise
With the Dynamic drive mode, cruise control'sacceleration and deceleration will be faster andmore immediate than in other drive modes.

Distance Alert*26
The Distance Alert27 function can help the driverbecome aware if the time interval to the vehiclein front is too short.
However, the vehicle must be equipped with ahead-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 vehiclesthat can display information on the wind-shield with a head-up display.
Distance Alert is deactivated while Adap-tive Cruise Control or Pilot Assist isactive.

Adaptive Cruise Control regulates speed byaccelerating 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 avehicle 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 collisionavoidance 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.
