328The
Late warning distance setting should there-
fore only be used in exceptional cases, such as when a more dynamic driving style is preferred.
WARNING
• No automatic system can guarantee 100% correct function in all situations.You should therefore never test use ofCity Safety in the direction of people, ani-mals or vehicles – this could lead tosevere damage, serious personal injury oreven death.
• City Safety warns the driver if there is arisk of collision, but the function cannotreduce the driver's reaction time.
• Even if the warning distance has been set to
Early, warnings may be perceived as
late in certain situations – e.g. when there are large speed differences or if the vehi-cle ahead suddenly brakes heavily.
• With the warning distance set to
Early,
warnings come further in advance. This may cause the warnings to come morefrequently than with warning distance
Normal, but is recommended since it can
make City Safety more effective.
NOTE
The warning with direction indicators for Rear Collision Warning is deactivated if the colli-sion warning distance in the City Safety func- tion is set to the lowest level "
Late".
The seat belt tensioning and braking func- tions remain active.

Detecting obstacles with City Safety City Safety can detect vehicles, cyclists, large animals and pedestrians.
VehiclesCity Safety detects most types of vehicles that are either stationary, moving in the same direc-tion as your vehicle or those described in "CitySafety in crossing traffic". For City Safety to be able to detect a vehicle in the dark, its headlights and taillights must be onand clearly visible.
Cyclists
Optimal examples of what City Safety would interpret to be a cyclist: clear body and bicycle shapes.
For optimal performance, the system's function for cyclist detection needs the clearest possibleinformation about the contours of the bicycle andof the cyclist's head, arm, shoulders, legs, torso

and lower body in combination with normal human movements. If large portions of the cyclist's body or the bicy- cle itself are not visible to the function's camera,it will not be able to detect a cyclist. The system can only detect adult cyclists riding on bicycles intended for adults.
WARNING
City Safety is supplementary driver support, but it cannot detect all cyclists in all situationsand, for example, cannot see:
• partially obscured cyclists.
• cyclists if the background contrast of the cyclist is poor - warning and brake inter-ventions may then be late or not occur atall.
• cyclists in clothing that hides their bodycontour.
• bikes loaded with large objects.
The driver is always responsible for ensuring that the vehicle is driven correctly and with asafety distance suitable for the speed.
Pedestrians
Optimal examples of what the system considers to be a pedestrian: clear body contours.
For optimal performance, the system's function for pedestrian detection needs the clearest pos-sible information about body and bicycle con-tours. This entails being able to detect the con-tours of the pedestrian's head, arm, shoulders,legs, torso and lower body in combination withnormal human movements. In order to detect a pedestrian, there must be a contrast to the background, which could dependon clothing, weather conditions, etc. If there is lit-tle contrast, the person may be detected late ornot at all, which may result in a delayed reactionfrom the system or no reaction at all. City Safety can detect pedestrians even in dark conditions if they are illuminated by the vehicle'sheadlights.
WARNING
City Safety is supplementary driver support, but it cannot detect all pedestrians in all sit-uations and, for example, cannot see:
• partially obscured pedestrians, people in clothing that hides their body contour orpedestrians shorter than 80 cm (32 in.).
• pedestrians if the background contrast ofthe pedestrians is poor - warning andbrake interventions may then be late ornot occur at all.
• pedestrians who are carrying largeobjects.
The driver is always responsible for ensuring
that the vehicle is driven correctly and with a safety distance suitable for the speed.

Large animals
Optimal examples of what City Safety would interpret as a large animal: stationary or moving slowly and with clearbody contours.
For optimal performance, the system's function for detecting large animals (e.g. moose, horses,etc.) needs the clearest possible informationabout body contours. This entails being able todetect the animal straight from the side in combi-nation with normal movements for that animal. If parts of the animal's body are not visible to the function's camera, the system will not be able todetect the animal. City Safety can detect large animals even in dark conditions if they are illuminated by the vehicle'sheadlights.
WARNING
City Safety is supplementary driver support, but it cannot detect all large animals in all sit-uations and, for example, cannot see:
• partially obscured larger animals.
• larger animals seen from the front or from behind.
• running or fast moving larger animals.
• larger animals if the contrast of the ani-mal's background is poor - warning andbrake interventions may then occur lateor not at all.
• smaller animals such as cats and dogs.
The driver is always responsible for ensuring that the vehicle is driven correctly and with asafety distance suitable for the speed.

City Safety in crossing traffic
City Safety can assist the driver when turning in the path of an oncoming vehicle in an intersec-tion.
: Sector in which City Safety can detect an oncoming
vehicle in crossing traffic.
In order for City Safety to detect an oncoming vehicle in situations where there is a risk of a col-lision, that vehicle must be within the sector inwhich City Safety can analyze the situation. The following criteria must also be met:
• your vehicle's speed must be at least 4 km/h (3 mph)
• your vehicle must be making a left turn
• the oncoming vehicle's headlights must beon

WARNING
•The "City Safety in crossing traffic" func- tion is supplementary driver supportintended to improve driving safety – itcannot handle all situations in all traffic,weather and road conditions.
• Warnings and brake interventions due toa collision risk with an oncoming vehicleoften come very late.
• Never wait for a collision warning or forCity Safety to intervene.
• City Safety is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Limitations of City Safety incrossing traffic
In certain situations, it may be difficult for City Safety to help the driver avoid a collision withcrossing traffic.
For example:
• on slippery roads when Electronic Stability Control (ESC) is actively operating
• if an approaching vehicle is detected at a latestage
• if the oncoming vehicle is partially obstructedby another vehicle or object
• if the oncoming vehicle's headlights are off
• if the oncoming vehicle is moving erraticallyand e.g. suddenly changes lanes at a latestage.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

City Safety limitations
City Safety functionality may be reduced in cer- tain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhanging loads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood, may limit City Safety function-ality.
Slippery road conditions
The extended braking distance on slippery roads may reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con- trol (ESC 73
) will help provide optimal braking
power with maintained stability.
Backlighting
The visual warning signal in the windshield may be difficult to detect in bright sunlight, if there arereflections, or if the driver is wearing sunglassesor not looking straight ahead.
Heat
If the temperature in the passenger compartment is high due to e.g. bright sunlight, the visual warn-ing signal in the windshield may be temporarilydisabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer- tain situations, it may be unable to detect pedes-trians, large animals, cyclists or vehicles, or it maydetect them later than expected. Vehicles that are dirty may be detected later than clean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all. If a text message displayed in the instrument panel indicates that the camera/radar sensor isobstructed, it may be difficult for City Safety todetect pedestrians, large animals, cyclists, vehi-cles or lane markings in front of the vehicle. CitySafety functionality may therefore be reduced. Text messages may not be displayed for all situa- tions in which the windshield sensors areblocked. The driver must therefore always keepthe windshield in front of the camera/radar sen-sor clean.
CAUTION
Maintenance and replacement of City Safety components may only be performed by aworkshop – an authorized Volvo workshop isrecommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds under 4 km/h (3 mph). The system will thereforenot intervene in situations in which your vehicle isapproaching another vehicle very slowly, such aswhen parking.
Active driver
Action by the driver always has priority. City Safety will therefore not react or will react at alater stage with a warning or intervention in situa-tions in which the driver is clearly steering andoperating the accelerator pedal, even if a collisionis unavoidable. An active and aware driving style may therefore delay collision warnings and intervention in order to minimize unnecessary warnings.

WARNING
•Warnings and brake interventions can be triggered late or not at all if the traffic sit-uation or external influences prevent thecamera and radar unit from properlydetecting pedestrians, cyclists, large ani-mals or vehicles ahead of the vehicle.
• To be able to detect vehicles at night, itsfront and rear lights must work and illumi-nate clearly.
• The camera and radar unit have a limitedrange for pedestrians and cyclists – thesystem can provide effective warningsand brake interventions if the relativespeed is lower than 50 km/h (30 mph).For stationary or slow-moving vehicles,warnings and brake interventions areeffective at vehicle speeds of up to70 km/h (43 mph). Speed reduction forlarge animals is less than 15 km/h(9 mph) and can be achieved at vehiclespeeds over 70 km/h (43 mph). At lowerspeeds, the warning and brake interven-tion for large animals is less effective.
• Warnings for stationary or slow-movingvehicles and large animals can be disen-gaged due to darkness or poor visibility.
• Warnings and brake interventions for pedestrians and cyclists are disengagedat vehicle speeds over 80 km/h(50 mph).
• Do not place, affix or mount anything onthe inside or outside of the windshield, orin front of or around the camera andradar unit – this could disrupt camera-based functions.
• Objects, snow, ice or dirt in the area ofthe camera sensor can reduce the func-tion, disengage it completely or give animproper function response.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

Ignition modes
The vehicle's ignition can be put in various modes (levels) to make different functions availa-ble.
To enable the use of a limited number of func- tions when the engine is not running, the ignition can be put in one of three different levels: 0, I
and II. These levels are referred to as "ignition
modes" in the Owner's Manual. The following table shows which functions are available in each ignition mode:
ModeFunctions
0 •The odometer, clock and tem- perature gauge are illuminated A

Brake Assist System
The brake enhancing system, Brake Assist
System (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habits and increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.
NOTE
When BAS is activated, the brake pedal will go down slightly more than usual. Press(hold) down the brake pedal as long as nec-essary. When the brake pedal is released, all braking ceases.

• Brakes (p. 399)
Braking on wet roads
Prolonged driving in heavy rain without braking may cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.
