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.

WARNING
• In certain situations, the system can- not provide warnings or warnings maybe delayed if traffic conditions or otherexternal factors make it impossible forthe radar sensor or camera to detect apedestrian, a cyclist or a vehicleahead.
• Warnings may not be provided if thedistance to the vehicle ahead is short,or if movements of the steering wheel/brake pedal are great, such as duringactive driving.
• The sensor system has a limited rangefor pedestrians/cyclists and provideswarnings and braking effect mosteffectively at speeds up to 30 mph(50 km/h). For stationary or slow-mov-ing vehicles, the system functions bestif your vehicle’s speed is belowapproximately 45 mph (70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full Auto Brake system uses the same radar sen-sors as Adaptive Cruise Control. For moreinformation on the radar sensor and its limita-tions, see Adaptive Cruise Control – limita-tions (p. 193).
NOTE
If warnings are given too frequently, the warning distance can be reduced (see Col-lision warning* – operation (p. 212)). Thiscauses the system to provide later warn-ings, which decreases the total number ofwarnings provided.
WARNING
•The system is not activated at speeds under approx. 2 mph (4 km/h). There-fore, it will not brake your vehicle if youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the Pedestrianand Cyclist Detection with Full AutoBrake system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.

Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the
camera is obscured and cannot detect pedestrians, cyclists, vehicles or road marker lines in front of the vehicle. This, in turn, means that Pedestrian and Cyclist Detection with Full Auto Brake, DriverAlert Control, Lane Departure Warning or
Lane Keeping Aid will not have full functional-ity. The table lists possible causes for this mes- sage being displayed, and suitable actions.
CauseAction
The surface of the windshield in front of the camera is dirty or covered with ice or snow.Clean or clear the section of the windshield in front of the camera.
Fog, heavy rain or snow is interfering with the function of the camera.No action possible. Heavy precipitation may affect the function of the camera.
The surface of the windshield is clean but the message remains in the display.Wait a short time. It may take several minutes for the camera to regis- ter visibility.
The surface between the inside of the windshield and the camera is dirty.Contact an authorized Volvo retailer or service technician to have this surface cleaned.

Windscreen Sen- sors blockedThe camera is temporarily not functioning. This message is displayed if the camera is obstructed by snow, ice, dirt, etc., on the windshield. Clean the area of the windshield in front of the camera, see The camera’slimitations (p. 217) for more information on the camera’s limitations.
Radar blocked See manualPedestrian and Cyclist Detection with Full Auto Brake is temporarily not functioning. The radar sensor is blocked, for example by heavy rain or snow that has accumulated in front of the sensor, and cannot detectother vehicles, see Adaptive Cruise Control – limitations (p. 193) for more information on the radar sensor’slimitations.

Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audiblesignal comes from the audio system's frontspeakers. It may not be possible to combine auxiliary headlights and front park assist since theselights could trigger the system's sensors.
NOTE
Front park assist is deactivated when the parking brake is applied and or when thegear selector is in the P position.

Location of the front sensors
Location of the rear sensors Ice and snow covering the sensors may cause incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt, snow, or ice, this could result in falsewarning signals from the park assist sys-tem.

Automatic car wash
The vehicle should be washed at regular inter- vals since dirt, dust, insects and tar spotsadhere to the paint and may cause damage.To help prevent corrosion, it is particularlyimportant to wash the car frequently in thewintertime.• We do NOT recommend washing your car in an automatic wash during the firstfew months (because the paint will nothave hardened sufficiently).
• An automatic wash is a simple and quickway to clean your car, but it is worthremembering that it may not be as thor-ough as when you yourself go over thecar with sponge and water. Keeping theunderbody clean is most important, espe-cially in the winter. Some automaticwashers do not have facilities for washingthe underbody.
NOTE
Condensation may form temporarily on the inside of the lenses of exterior lights suchas headlights, fog lights, or taillights. Thisis normal and the lights are designed towithstand moisture. Normally, condensa-tion will dissipate after the lights have beenon for a short time.
CAUTION
• Before driving into an automatic car wash, turn off the optional rain sensorto avoid damaging the windshield wip-ers.
• Make sure that side view mirrors, aux-iliary lamps, etc, are secure, and thatany antenna(s) are retracted orremoved. Otherwise there is risk of themachine dislodging them.
• Chromed wheels:
Clean chrome-
plated wheels using the same deter-gents used for the body of the vehicle.Aggressive wheel-cleaning agents canpermanently stain chrome-platedwheels.
WARNING
• When the vehicle is driven immediately after being washed, apply the brakes,including the parking brake, severaltimes in order to remove any moisturefrom the brake linings.
• Engine cleaning agents should not beused when the engine is warm. Thisconstitutes a fire risk.

Polishing and waxing
Normally, polishing is not required during the first year after delivery, however, waxing maybe beneficial.
• Before applying polish or wax the vehicle must be washed and dried. Tar spots canbe removed with kerosene or tar remover.Difficult spots may require a fine rubbingcompound.
• After polishing use liquid or paste wax.
• Several commercially available productscontain both polish and wax.
• Waxing alone does not substitute for pol-ishing a dull surface.
• A wide range of polymer-based waxescan be purchased today. These waxesare easy to use and produce a long-last-ing, high-gloss finish that protects thebodywork against oxidation, road dirt andfading.
• Do not polish or wax your vehicle in directsunlight (the surface of the vehicle shouldnot be warmer than 113 °F (45 °C).
