Distance Warning* - limitations
Distance Warning (Distance Alert) is a function that informs the driver about the distance tovehicles in front. The function uses the sameradar sensor as the Adaptive cruise control (p.188) and Collision warning with auto brake (p.212), has some limitations.
NOTE
Strong sunlight, reflections or strong varia- tions in light intensity, as well as wearingsunglasses, could mean that the warninglight in the windscreen cannot be seen. Poor weather or winding roads could affect the radar sensor's capacity to detectvehicles in front. The size of other vehicles could also affect detection capacity, e.g. motorcycles. Thiscould mean that the warning lamp illumi-nates at a shorter distance than the settingor that the warning is temporarily absent. Extremely high speeds can also cause the lamp to illuminate at a shorter distancethan that set due to limitations in sensorrange.
For further information on radar sensor limita- tions, see Radar sensor - limitations (p. 197)and (p. 218).

City Safety™
City Safety™ is a function for helping the driver to avoid a collision when driving inqueues, amongst other things, when changesin the traffic ahead, combined with a lapse inattention, could lead to an incident. The City Safety™ function is active at speeds under 50 km/h and it helps the driver by auto-matically braking the car in the event of immi-nent risk of collision with vehicles in front,should the driver not react in time by brakingand/or steering away. City Safety™ is activated in situations where the driver should have started braking earlier,which is why it cannot help the driver in everysituation. City Safety™ is designed to be activated as late as possible in order to avoid unnecessaryintervention. City Safety™ must not be used as an excuse for the driver to change his/her driving style. Ifthe driver solely relies on City Safety™ to dothe braking, there will be a collision sooner orlater. The driver or passengers normally only notice City Safety™ if a situation arises where thecar is extremely close to being in a collision. If the car is also equipped with Collision Warning with Auto Brake (p. 212)* these twosystems complement each other.IMPORTANT
Maintenance and replacement of City Safety™ components must only be per-formed by a workshop - an authorisedVolvo workshop is recommended.
WARNING
City Safety™ does not engage in all driv- ing situations or traffic, weather or roadconditions. City Safety™ does not react to vehicles driving in a different direction from the car,to small vehicles and motorcycles or tohumans and animals. City Safety™ can prevent collision at a speed difference of less than 15 km/h - ata higher speed difference, it is only possi-ble to reduce collision speed. In order toobtain full brake function, the driver mustdepress the brake pedal. Never wait for City Safety™ to engage. The driver always bears responsibility formaintaining the proper distance andspeed.

City Safety™ - function
City Safety™ detects the traffic in front of the car with a laser sensor fitted in the top edgeof the windscreen. If there is an imminent riskof collision, City Safety™ will automaticallybrake the car, which may be experienced assudden braking.

.
If the speed difference is 4-15 km/h in relation to the vehicle in front then City Safety™ cancompletely prevent a collision. City Safety™ activates a short, sharp braking and stops the car in normal circumstances,just behind the vehicle in front. For most dri-vers this is well outside normal driving styleand may be experienced as being uncomfort-able. If the difference in speed between the vehi- cles is greater than 15 km/h then CitySafety™ may not prevent the collision on itsown. To obtain full brake force, the drivermust depress the brake pedal. This couldthen make it possible to prevent a collision,even at speed differences above 15 km/h. When the function is activated and brakes,the combined instrument panel shows a textmessage to the effect that the function is/hasbeen active.
NOTE
When City Safety™ brakes, the brake lights come on.

City Safety™ - operation
City Safety™ is a function for helping the driver to avoid a collision when driving inqueues, amongst other things, when changesin the traffic ahead, combined with a lapse inattention, could lead to an incident.
On and Off
NOTE
The City Safety™ function is always switched on after the engine has beenstarted via key position
I and II (p. 70).
In certain situations, it may advisable to disa- ble City Safety™, e.g. where leafy branchescould sweep over the bonnet and/or wind-screen. After starting the engine City Safety™ can be deactivated as follows: The function can beactivated/deactivated in the menu system MY
CAR . For a description of the menu system,
see MY CAR (p. 103). However, the function will be enabled the next time the engine is started, regardless ofwhether the system was enabled or disabledwhen the engine was switched off.

City Safety™ - limitations
The sensor in City Safety™ is designed to detect cars and other large vehicles in front ofthe car irrespective of whether it is day ornight. However, the function has a number oflimitations. However, the sensor has limitations and has poorer functionality - or none at all - in e.g.heavy snowfall or rain, dense fog, duststorms or white-out situations. Mist, dirt, iceor snow on the windscreen may disrupt thefunction. Low-hanging objects, e.g. a flag/pennant for projecting load, or accessories such as auxili-ary lamps and bull bars that are higher thanthe bonnet limit the function. The laser beam from the sensor in City Safety™ measures how the light is reflected.The sensor cannot detect objects with lowreflection capacity. The rear sections of thevehicle generally reflect the light sufficientlythanks to the number plate and rear lightreflectors. On slippery road surfaces the braking dis- tance is extended, which may reduce thecapacity of City Safety™ to avoid a collision.In such situations the ABS and DSTC sys-tems will provide best possible braking forcewith maintained stability. When your own car is reversing, City Safety™ is temporarily deactivated. City Safety™ is not activated at low speeds -under 4 km/h, which is why the system doesnot intervene in situations where a vehicle infront is being approached very slowly, e.g.when parking. Driver commands are always prioritised, which is why City Safety™ does not intervenein situations where the driver is steering oraccelerating in a clear manner, even if a colli-sion is unavoidable. When City Safety™ has prevented a collision with a stationary object the car remains sta-tionary for a maximum of 1.5 seconds. If thecar is braked for a vehicle in front that is mov-ing, then speed is reduced to the same speedas that maintained by the vehicle in front. On a car with manual gearbox the engine stops when City Safety™ has stopped thecar, unless the driver manages to depress theclutch pedal beforehand.
NOTE
•
Keep the windscreen surface in front of the laser sensor free from ice, snowand dirt (see the illustration for sensorlocation (p. 205)).
• Do not affix or mount anything on thewindscreen in front of the laser sensor
• Remove ice and snow from the bonnet- snow and ice must not exceed aheight of 5 cm.

Collision warning system*
"Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is an aid toassist the driver when there is a risk of collid-ing with a pedestrian, bicycle or vehicle infront that are stationary or moving in the samedirection. Collision Warning with Auto Brake & Pedes- trian Detection is activated in situations wherethe driver should have started braking earlier,which is why it cannot help the driver in everysituation. Collision Warning with Auto Brake & Pedes- trian Detection is designed to be activated aslate as possible in order to avoid unnecessaryintervention. Collision Warning with Auto Brake & Pedes- trian Detection may prevent a collision orreduce the collision speed. Collision Warning with Auto Brake & Pedes- trian Detection must not be used as anexcuse for the driver to change his/her drivingstyle. If the driver solely relies on CollisionWarning with Auto Brake to do the braking,there might be a risk of a collision sooner orlater.
Two system levelsThe Collision Warning with Auto Brake &Pedestrian Detection function is available in two variants, depending on how the car isequipped: Level 1 The driver is merely warned
14
of occurring
obstacles by means of visual and acoustic signals - no automatic braking intervenes, thedriver must himself brake. Level 2 The driver is warned of occurring obstacles by means of visual and acoustic signals - thecar is braked automatically if the driver him-self does not act within a reasonable time.
IMPORTANT
Maintenance of components included in Collision Warning with Auto Brake &Pedestrian Detection must only be carriedout in a workshop - an authorised Volvoworkshop is recommended.

Collision warning system* - function

Audio-visual warning signal in the event of a collision risk.
Radar sensor 16
Camera sensor
Collision Warning with Auto Brake executes three steps in the following order: 1. Collision warning
2. Brake support 16 3.
Auto Brake 16
The collision warning system and City Safety™ (p. 205) complement each other.
1 - Collision warningThe driver is first warned of a potentiallyimminent collision. The collision warning system detects pedes- trians, stationary vehicles as well as vehiclesdriving in the same direction in front of thecar. If there is a risk of collision with a pedestrian or a vehicle then the driver's attention isattracted with a flashing red warning signal (1)and an acoustic signal.
2 - Brake support 16If the risk of collision has increased furtherafter the collision warning then the brake sup-port is activated. This means that the brake system is prepared for rapid braking by applying the brakeslightly, which may feel like a slight jolt. If the brake pedal is depressed sufficiently quickly then full brake function is imple-mented. Brake support also reinforces the driver's braking if the system considers that the brak-ing is not sufficient to avoid a collision.
3 - Auto Brake
16The automatic brake function is activatedlast. If in this situation the driver has not yet started to take evasive action and the risk ofcollision is imminent then the automatic brak-ing function is deployed - this takes placeirrespective of whether or not the driverbrakes. Braking then takes place with fullbrake force in order to reduce collision speed,or with limited brake force if it is sufficient toavoid a collision. For cyclists, the warning andfull brake intervention may come very late orsimultaneously.
