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. 162)) 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. 190).
• 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. 190)). 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).

Pedestrian and Cyclist Detection with Full Auto Brake is designed to assist the driver ifthere is a risk of a collision with a pedestrian,a cyclist, a vehicle ahead that is at a standstillor one that is moving in the same direction asyour vehicle. This system consists of the following three functions: • Collision Warning
warns the driver of a
potential collision situation.
• Brake Support
helps the driver brake
efficiently in a critical situation.
• Auto-brake
brakes the vehicle automati-
cally if a collision with a pedestrian, a cyclist or another vehicle cannot be avoi-ded and the driver does not apply thebrakes in time or steer around the per-son/vehicle. Auto-brake can help preventa collision or reduce the speed at which acollision occurs.
Since Pedestrian and Cyclist Detection with Full Auto Brake is activated in circumstanceswhere the driver should have begun brakingmuch sooner, the system will not be able toassist the driver in all situations. This system is designed to activate as late as possible to help avoid unnecessary interven-tion. The system should not be used in such a way that the driver changes his/her way of operat- ing the vehicle. If the driver relies entirely onthe system, the chances of an accident even-tually occurring increase considerably. The Pedestrian and Cyclist Detection with Full Auto Brake and City Safety™ systems sup-plement each other. See City Safety – intro-duction (p. 189) for detailed information aboutCity Safety™.
WARNING
No automatic system can be guaranteed to function 100% correctly in all situations.For that reason, never test the Auto-brakesystem by driving toward a person orobject. This could result in serious injury ordeath.

WARNING
• Pedestrian and Cyclist Detection with Full Auto Brake does not work in alldriving, traffic, weather and road con-ditions. It does not react to vehiclesnot traveling in the same direction asyour vehicle.
• Pedestrian and Cyclist Detection withFull Auto Brake does not react to ani-mals.
• Warnings are only provided when therisk of collision is high. The "Function"section provides information aboutlimitations that the driver must beaware of before using Collision Warn-ing.
• Pedestrian and Cyclist Detection withFull Auto Brake will not provide awarning or brake the vehicle forpedestrians or cyclists at speedsabove 50 mph (80 km/h).
WARNING
•
Pedestrian and Cyclist Detection with Full Auto Brake will not provide awarning or brake the vehicle forpedestrians in darkness or in tunnels,even if there is street lighting in thearea.
• The auto-brake function can help pre-vent a collision or reduce the speed atimpact but the driver should alwaysapply the brakes for the best possiblebraking effect, even if auto-brake isactively applying the brakes.
• Never wait for a collision warning. Thissystem is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's atten-tion and judgement. The driver isresponsible for maintaining a safe dis-tance and speed, even when the colli-sion warning system is in use.
• Maintenance of the Pedestrian andCyclist Detection with Full Auto Brakesystem's components must only beperformed by a trained and qualifiedVolvo technician.

Collision warning* – function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work together to detect a pedestrian, a cyclist, sta-tionary vehicles and vehicles that are movingin the same direction as your vehicle. If thereis a risk of collision with a vehicle, a cyclist ora pedestrian, the driver is alerted by a flash-ing red warning light and an audible warningsignal. The system is active at speeds above3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increaseafter the collision warning has been given,Brake Support is activated. Brake Supportprepares the brake system to react quickly,and the brakes are applied slightly. This maybe experienced as a light tug. If the brakes are applied quickly, full braking effect will be provided. Brake Support alsoincreases brake force if the system deter-mines that the driver has not applied ade-quate pressure on the brake pedal.
Auto-brakeIf a collision is imminent and the driver hasnot applied the brakes or begun to steeraround the vehicle, pedestrian or a cyclist,the auto-brake function is activated withoutthe driver pressing the brake pedal. Full brakeforce is applied to help reduce the vehicle’sspeed when the collision occurs or limitedbrake force is applied if this is sufficient toavoid the collision.
NOTE
The auto-brake and brake support func- tions are always on and cannot be turnedoff.
