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
Audible 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 the same 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.

The following table shows some of the situations that can cause the message to be displayed andsuggested actions.
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.
There is dirt betweenthe inside of the wind-shield and the camera/radar sensor. Have the area ofthe windshieldcleaned by atrained and quali-fied Volvo servicetechnician.
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 City Safety to function properly, the area of the windshield must be kept free of dirt,ice, snow, etc.
Other vehicle functionsIf a message is displayed in the instrument panel,this means that the other systems using the cam-era/radar sensor (see the list below) will not havefull functionality or may not function at all. The camera and radar sensor is used by the fol- lowing functions: • Distance Alert
*
• Driver Alert Control
*
• Adaptive Cruise Control
*
• Pilot Assist
*
• Run-off Mitigation
• Road Sign Information
*
• Active High Beams

Camera and radar sensor's field of vision
The camera and radar sensor have limited fields of vision. In some situations they may detect avehicle, large animal, pedestrian or cyclist laterthan expected or not detect them at all. Other vehicles that are dirty may be detected later than others and in dark conditions, motorcy-cles may be detected late or not at all. If a text message is displayed in the instrument panel indicates that the camera or radar sensorare blocked, it may be difficult for City Safety todetect a vehicle, pedestrian or cyclist and thesystem's functionality may be reduced.
WARNING
Text messages may not be displayed in all sit- uations in which the camera and/or radarsensor are blocked. It is therefore essential tokeep the windshield in front the camera/radarsensor clean and free from snow, ice, etc. Camera and radar sensor components should only be serviced or replaced by a trained andqualified Volvo service technician.
Action by the driver
Backing up
City Safety is temporarily deactivated while the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds (under approx. 3 mph (4 km/h). This means thatthe system will not be triggered if your vehicleapproaches a vehicle ahead at very low speed,such as when parking.
Active driver
Action by the driver always has priority. For this reason, City Safety may not react or react laterthan expected in situations in which the driver isactively operating the vehicle, even if a collision isimminent. This is also done to help eliminateexcessive warnings.
Other limitations
City Safety uses the vehicle's camera and radar sensor, which have certain general limitations.See the articles "Camera limitations" and "Radarsensor limitations" for additional information.
WARNING
•
Warnings and braking may be delayed or not occur at all if traffic, weather or otherconditions prevent the camera and/orradar sensor from detecting pedestrians,cyclists, large animals or other vehiclescorrectly.
• Other vehicles can only be detected indarkness if their headlights and taillightsare clearly visible.
• The sensors have a limited range forpedestrians and cyclists. The systemfunctions best at relative speeds up to30 mph (50 km/h). For stationary orslow-moving vehicles, the system func-tions best at speeds up to approx.43 mph (70 km/h).
• If there is a risk of colliding with a largeanimal, City Safety can reduce the vehi-cle's speed by up to 9 mph (15 km/h).Warnings and braking are most effectiveat speeds above 43 mph (70 km/h) andless effective at lower speeds.

Blind Spot Information (BLIS) *
limitations
Blind Spot Information functionality may be reduced in certain situations.
• Dirt, ice and snow on the sensors may reduce functionality and prevent the systemfrom providing warnings.
• Do not attach any objects, tape, decals, etc.,on the surface of the sensors.
• BLIS is deactivated if a trailer is attached tothe vehicle's electrical system.
Maintenance
The BLIS/CTA 5
sensors are located on the
inside of the rear fenders/bumper.
Keep the highlighted area clean (on both sides of the vehicle) - generic illustration
For the system to function optimally, the area over and around the sensors must be kept clean.
CAUTION
Repairs to the BLIS/CTA systems and/or repainting the rear bumper should only bedone by a trained and qualified Volvo servicetechnician.

Cross Traffic Alert (CTA) *
Cross Traffic Alert (CTA) is a supplementary part of Blind Spot Information and is intended todetect vehicles crossing behind your vehiclewhile you are backing up.
When does Cross Traffic Alert function
Principle for CTA
CTA supplements BLIS by warning the driver of crossing traffic behind your vehicle, for example,when backing out of a parking space. It is primarily designed to detect another vehicle but in certain cases may also detect pedestriansor smaller objects such as bicycles. CTA is only activated when the vehicle is rolling rearward or when the gear selector is put inreverse.
