WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Standby mode due to action by the driver
ACC is temporarily deactivated and put in standby mode:
• if the brakes are applied
• if the gear selector is moved to
N
• if the driver drives faster than the set speed for more than
1 minute.
In this happens, the driver will have to regu- late the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passinganother vehicle, ACC is deactivated tem-porarily and is reactivated when the pedalis released.
Automatic standby modeACC is linked to other systems such as the stability system. If this system is not function-ing properly, ACC will switch off automati-cally. In the event of automatic deactivation, an audible signal will sound and the message
Cruise control Cancelled is shown in the
instrument panel. The driver must then inter- vene and adapt the vehicle's speed to thesurrounding traffic and regulate the distanceto the vehicle ahead. An automatic switch to standby mode may be caused if:
• engine speed (rpm) is too high/low
• The driver's door is opened
• The driver unbuckles his/her seat belt
• the vehicle's speed goes below 18 mph (30 km/h)
• the wheels lose traction
• brake temperature is high
• the radar sensor is obstructed by, forexample, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactiva- ted by pressing the
button on the steering
wheel keypad. The vehicle will return to the most recently set speed.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.

-Cruise control Cancel- ledACC has been automatically switched off. The driver has to regulate the vehicle’s speed/distance to the vehicle ahead.
-Cruise control Unavail- ableACC cannot be put in active mode. This may be due to: • high brake temperature
• the radar sensor is obstructed (by heavy rain, snow, etc.)
Radar blocked See manualACC has been temporarily disconnected because the radar is obstructed in some way and cannot detect other vehicles. In this situation, the driver can switch to standard cruise control, see Toggling between ACC and CC (standard Cruise Control) (p. 149) See Adaptive Cruise Control – limitations (p. 159) for information on the radar sensor’s limitations.

Adaptive Cruise Control – troubleshooting
If the message Radar blocked See manualis displayed, this means that the radar signalsfrom the sensor have been obstructed and that a vehicle ahead cannot be detected. This, in turn, means that the functions of the ACC, Distance Alert, and Collision Warning
System with Auto-brake and PedestrianDetection will not function. The table lists possible causes for this mes- sage being displayed, and suitable actions.
CauseAction
The surface of the radar in the grille is dirty or obstructed in some way.Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the radar.
Swirling water or snow from the surface of the road may interfere with the radar signals.No action possible. A very wet or snow-covered road surface may affect the function of the radar.
The surface of the radar is clean but the message remains in the display.Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed.

decrease it.
Five different time intervals can be selected and areshown in the display as 1–5horizontal bars. The greaterthe number of bars, thelonger the time interval. Onebar represents approximately
1 second to the vehicle ahead; 5 bars isapproximately 3 seconds.
NOTE
• The higher your vehicle’s speed, the greater the distance to the vehicleahead, measured in feet (meters), for agiven time interval.
• The set time interval is also used byAdaptive Cruise Control, see AdaptiveCruise Control – setting speed (p. 154).
WARNING
Only use a time interval that is suitable in current traffic conditions.

Distance Alert – limitations
Distance Alert is part of Adaptive Cruise Con- trol and is a function that provides informationabout the time interval to the vehicle ahead.
LimitationsDistance Alert uses the same radar sensorused by Adaptive Cruise Control and the Col-lision Warning system. See Adaptive CruiseControl – limitations (p. 159) for more infor-mation on the radar sensor’s limitations.
NOTE
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead maymake the visual warning signal in the wind-shield difficult to see.
WARNING
•Bad weather or winding roads may affect the radar sensor’s capacity todetect vehicles ahead.
• The size of the vehicle ahead, such asa motorcycle, may also make it difficultto detect. This may result in the warn-ing light illuminating at a shorter dis-tance than the one that has been set,or that the light will not come on at all.

City Safety – function
FunctionCity Safety™ monitors traffic ahead of you using a laser sensor mounted in the uppersection of the windshield. If a collision isimminent, City Safety™ will automaticallyapply the brakes, which may feel like hardbraking. If the difference in speed between your vehi- cle and the vehicle ahead is more thanapproximately 9 mph (15 km/h), City Safety™alone cannot prevent a collision from takingplace. The driver must apply the brakes tohelp avoid a collision or reduce its effect. When the function activates and applies the brakes, a message will appear in the informa-tion display to indicate that the system is/hasbeen active.
NOTE
•When City Safety™ applies the brakes, the brake lights will illuminate.
• In cases where City Safety™ has stop-ped the vehicle, the system will thenrelease the brakes. The driver mustapply the brakes to keep the vehicle ata standstill.

City Safety – troubleshooting
Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the City Safety™ laser sensor is obstructed insome way and cannot detect vehicles aheadof you, which means that the system is notfunctioning. However, this message will not be displayed in all situations in which the sensor isobstructed. For this reason, the driver mustensure that the area of the windshield in frontof the sensor is always kept clean. The following table shows some of the situa- tions that can cause the message to be dis-played and suggested actions.
CauseAction
The area of the wind- shield in front of the sen-sor is dirty or covered byice or snow.Clean the windshield orremove the ice/snow.
The laser sensor's field of view is obstructed.Remove the obstruction.
NOTE
If a crack, scratch or stone chip should occur in the section of the windshield infront the laser sensor, contact a trainedand qualified Volvo service technician torepair or replace the windshield (see theillustration showing the location of the sen-sor in City Safety – function (p. 169)). Fail-ing to do so may result in reduced CitySafety™ functionality. To help prevent limited or reduced func- tionality, please also observe the following:
• Volvo recommends that cracks, scratches or stone chips on the wind-shield in front of the laser sensorshould not
be repaired; in such cases,
the entire windshield should bereplaced.
• Before the windshield is replaced,contact a Volvo retailer to ensure thatthe correct windshield is ordered andinstalled. If the wrong type of wind-shield is used, this may cause CitySafety™ to function improperly or notat all. Volvo recommends the use ofonly Genuine Volvo ReplacementWindshields.
• When replacing windshield wipers, usethe same type or ones approved byVolvo.
