Time interval: Increase/decrease
Time interval On
Press
to increase the interval or to
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 – operation
Using City Safety™
NOTE
The City Safety™ function is activated automatically each time the engine hasbeen switched off and restarted.
On and OffIn certain situations, it may be desirable to switch City Safety™ off, such as when drivingin close quarters where leaves, branches, etc.may obscure the hood and windshield. When the engine is running, City Safety™ can be switched off as follows: Press My Car in the center console control
panel and go to
SettingsCar settings
Driver support systemsCity Safety.
Select
Off.
If the engine is switched off, City Safety™ will reactivate when the engine is restarted.
WARNING
The laser sensor emits light when the igni- tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
• Follow the same procedure as for switch- ing City Safety™ off but select
On.

City Safety – limitations
Limitations
WARNING
The laser sensor has certain limitations and its function may be reduced (or it maynot function at all) in conditions such asheavy rain or snowfall, or by dense fog orthick, blowing dust or snow. Condensa-tion, dirt, ice or snow on the windshieldmay also interfere with the sensor’s func-tion.
The sensor used by City Safety™ is designed to detect cars and other larger motor vehiclesahead of your vehicle in both daylight anddarkness. Objects such as warning flags hanging from long objects on the roof or accessories suchas auxiliary lights or protective arches on thefront of the vehicle that are higher than thehood may also impede the sensor’s function. Braking distance to the vehicle ahead increa- ses on slippery road surfaces, which mayreduce City Safety’s capacity to avoid a colli-sion. In situations like this, the stability sys-tem (see Stability system – introduction(p. 141)) will help provide the best possiblebraking capacity and stability. City Safety™ emits a laser beam and meas- ures the way in which the light is reflected.

Therefore, vehicles or objects with low-reflec- tive surfaces may not be detected. Normally,the license plate and taillight reflectors givethe rear section of a vehicle ahead sufficientreflective surfaces to be detected.
NOTE
•
Keep the windshield in front of the laser sensor free of ice, snow, dirt,etc., see City Safety – function(p. 169).
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sen-sor. Keep the hood free of ice andsnow.
• Do not mount or in any way attachanything on the windshield that couldobstruct the laser sensor.

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.

City Safety – Laser sensor
The laser sensor
The upper decal describes the laser beam's classification and contains the following text: Invisible Laser radiation – Do not view directly with optical instruments (magnifiers) – Class1M laser product. The lower decal describes the laser beam's physical data and contains the text: IEC 60825-1:1993 + A2:2001. Complies with FDA performance standards for laser prod-ucts except for deviations pursuant to LaserNotice No. 50, dated July 26th, 2001 The laser beam's physical data is listed in the following table:
Maximum pulse energy2.64 μJ
Maximum average output45 mW
Pulse length33 ns
Divergence (horizontal × verti- cal)28° × 12°
NOTE
The function of aftermarket laser detectors may be affected by City Safety's laser sen-sor.
WARNING
The laser sensor emits light when the igni- tion is in mode II or higher, even if City
Safety™ has been switched off.
WARNING
Eye injury may occur if any of the following points are not followed: • It is essential that all pertinent instruc- tions be followed when handling laserinstruments. Testing, repairing, remov-ing, adjusting and/or replacing anycomponents in the laser sensor mayonly be done by a trained and qualifiedVolvo service technician.
• Do not remove the laser sensor(including removal of the lenses). Alaser sensor that has been removedbelongs to laser class 3B according tostandard IEC 60825-1. Devices in laserclass 3B present a risk of injury to theeyes.
• The laser sensor’s connector must bedisconnected before the sensor isremoved from the windshield.
• The laser sensor must be mounted inplace on the windshield before con-necting the sensor’s connector.
• Do not view the laser sensor (whichemits spreading, invisible laser beams)with optical instruments from a dis-tance of less than 4 inches (100 mm).
