Vehicle's speedThe radar sensor's capacity to detect vehicles ahead is impeded:
• if the speed of the vehicle ahead differsgreatly from your vehicle's speed.
Limited field of visionThe radar sensor has a limited field of vision. Insome situations it may detect a vehicle later thanexpected or not detect other vehicles at all.
Radar sensor's field of vision
In certain situations, the radar sensor cannot detect vehicles at close quarters, for examplea vehicle that suddenly enters the lanebetween your vehicle and the target vehicle.
Small vehicles, such as motorcycles, or vehi- cles not driving in the center of the lane mayremain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the target vehi-cle.
Low trailer in the radar shadow (generic illustration)
Low trailers may also be difficult to detect or may not be detected at all. The driver should be extraalert in situations of this type.
High temperaturesIf the temperature in the passenger compartmentis very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically.

CAUTION
•Service and maintenance on City Safety may only be carried out by a trained andqualified Volvo service technician.
• If a crack, scratch or stone chip shouldoccur in the section of the windshield infront the camera/radar sensor, contact atrained and qualified Volvo service techni-cian to repair or replace the windshield.Failing to do so may result in reducedCity Safety functionality.
• This can also result in certain functionsbeing reduced or disabled, or they mayrespond incorrectly.
To help avoid the risk of incorrect, reduced ordisabled functionality for driver support sys-tems using the camera or radar sensors:
• Volvo recommends that cracks, scratchesor stone chips on the windshield in front of the camera/radar sensor should
not
be repaired; in such cases, the entire windshield should be replaced.
• Before the windshield is replaced, con-tact a Volvo retailer to ensure that thecorrect windshield is ordered and instal-led. If the wrong type of windshield isused, this may cause City Safety to func-tion improperly or not at all.
• Volvo recommends the use of only Genu-ine Volvo Replacement Windshields.
• When replacing windshield wipers, use the same type or ones approved by Volvo.
After the windshield has been replaced, thecamera/radar sensor will have to be recalibra-ted by a trained and qualified Volvo servicetechnician to help ensure proper function ofall of the vehicle's camera-/radar-based sys-tems.
MaintenanceIn order for camera and radar sensor to function properly, the area of the windshield must be keptfree of dirt, ice, snow, etc. and should be washedregularly with a suitable car washing detergent.
NOTE
Dirt, ice and/or snow covering the camera and radar sensors reduce functionality andmay disable the vehicle's camera-/radar-based systems. This can also result in certain functions being reduced or disabled, or they may respond incorrectly.

CauseAction
Water or snow on the surface of the road swirl up and block radar signals or the camera's view. No action. The driver should be extra alert in conditions of this type.
There is dirt between the inside of the windshield and the camera/radar sensor. Have the area of the windshield cleaned by a trained and qualified Volvo service technician.
Strong backlighting No action required. The came will reset automatically when lightingconditions improve.

City Safety™
City Safety ™ is a support system designed to
help alert the driver to pedestrians, cyclists, large animals and vehicles that may appear suddenlyin front of your vehicle by providing visual, audi-ble and haptic alerts. The vehicle will brake auto-matically if the driver is unable to react quicklyenough.
City Safety introduction
Location of the camera and radar sensor (generic illus- tration)
City Safety can help prevent a collision or lower the vehicle's speed at the point of impact.
WARNING
• City Safety
™ is a supplemental aid to the
driver. It can never replace the driver

WARNING
Warnings will only be provided if there is an imminent risk of a collision taking place. Thedriver should be aware of the system's limita-tions before operating the vehicle. Warnings and automatic braking for pedes- trians and cyclists are deactivated at speedsabove approx. 43 mph (70 km/h). City Safety's auto-brake function can help prevent a collision or reduce the speed atwhich a collision occurs. However, the drivershould always apply the brakes, even if auto-brake is operating. The driver is always responsible for maintain- ing the correct speed and distance in relationto the vehicle ahead. Never wait for a collisionwarning or for City Safety to intervene. City Safety does not activate the auto-brake function during fast acceleration. City Safety maintenance may only be carried out by a trained and qualified Volvo servicetechnician.
Function overview
Audio-visual collision warning
Distance monitoring by a camera and radar sensor
When triggered, City Safety carries out threesteps in the following order: 1. Collision warning
2. Brake assistance
3. Auto-brake
1: Collision warningThe driver is first alerted to the risk of an immi- nent collision. City Safety can detect pedestrians, cyclists or vehicles that are stationary, are moving in thesame direction as your vehicle or are in your vehi-cle's path. City Safety can also detect pedestrians, large ani-mals or cyclists that are crossing in front of yourvehicle. If there is a risk of a collision with a pedestrian, cyclist, large animal or a vehicle, as well as vehi-cles described in the article "City Safety in cross-ing traffic," the driver will be alerted by a flashingred warning signal, an audible signal and a hapticwarning in the form of pulsations in the brakepedal. At lower speeds, during hard braking or ifthe accelerator pedal is pressed, the haptic warn-ing will not be given.
2: Brake assistanceIf the risk of a collision increases, brake supportwill be activated. This function increases pressure on the brake pedal if the driver does not apply enough pres-sure to the pedal.
3: Auto-brakeThe brakes will be applied automatically. If the driver has not taken action at this stage and a collision is imminent, auto-braking will be trig-gered. Full braking effect will be used to avoidthe collision if possible or to make the speed atthe point of impact as low as possible. In certain situations, auto-braking may begin with limited effect before full braking is used. If City Safety has prevented a collision, the vehi- cle will be kept at a standstill until the driver

Cause
Action
The area of the wind- shield in front of thecamera/radar sensor isdirty or covered by ice orsnow. Clean the wind-shield or removethe ice/ snow.
Thick fog or heavy rain/snow blocks reduces thecamera/radar sensor'srange of visibility. No action. Thedriver should beextra alert in condi-tions of this type.
