.
In order to function properly, the camera and laser sensor must be kept clean. Dirt, ice,snow, etc., will reduce the function of thesecomponents. Remove ice and snow when necessary and wash these areas regularly with a suitable carwashing liquid.
Limitations
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead may makethe visual warning signal in the windshield dif-ficult to see. For this reason, always activatethe audible warning signal. Slippery driving conditions increase braking distance, which can reduce the system'scapacity to avoid a collision. In these condi-tions, the ABS and DSTC systems providethe best possible braking effect while helpingto maintain stability.
NOTE
The visual warning signal may be tempo- rarily disengaged in the event of high pas-senger compartment temperature due tostrong sunlight, etc. If this occurs, theaudible warning signal will be used, even ifit has been deactivated in the menu sys-tem.
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 or a vehicle ahead.
• 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 and provides warningsand braking effect most effectively atspeeds up to 30 mph (50 km/h). Forstationary or slow-moving vehicles, thesystem functions best if your vehicle’sspeed is below approximately 45 mph(70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Collision Warning system uses the same radar sensors as Adaptive Cruise Control. Formore information on the radar sensor and itslimitations, see page 155.

Pedestrians
The system cannot identify all pedestrians
The Collision Warning system can only iden- tify and detect a pedestrian who is standingupright. This person can be standing still,walking or running. This means that the system has to be able to identify a person's head, arms, shoulders,legs, the upper and lower parts of the bodyand a person's pattern of movement whenwalking or running. If parts of the body are not visible to the cam- era, the system cannot detect the pedestrian. The following conditions apply:
• In order to detect a pedestrian, the sys- tem must have a full view of the person'sentire body and the person must be atleast 32 in. (80 cm) tall.
• The system cannot detect a pedestriancarrying a large object.
• The camera's capacity to see a pedes-trian at dawn or dusk is limited, much asit is for the human eye.
• The camera's function is deactivated andwill not detect a pedestrian in darkness orin tunnels, even if there is street lighting inthe area.
WARNING
• Collision Warning with Full Auto-brake and Pedestrian Detection is designedto be a supplementary driving aid. It isnot, however, intended to replace thedriver's attention and judgement. Thedriver is always responsible for operat-ing the vehicle in a safe manner.
• The system cannot detect all pedes-trians in all situations, such as in dark-ness/at night and cannot detect parti-ally hidden pedestrians, people whoare less than approx. 32 in. (80 cm)tall, or people wearing clothing thatobscures the contours of their bodies.
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the
camera is obscured and cannot detect pedestrians, vehicles or road marker lines infront of the vehicle. This, in turn, means that Collision Warning with Full Auto-brake and Pedestrian Detec-tion, Lane Departure Warning, and DriverAlert Control will not have full functionality. The table lists possible causes for this mes- sage being displayed, and suitable actions.

Park assist*
04
182* Option/accessory, for more information, see Introduction.
Introduction
The park assist system is designed to assist you when driving into parking spaces,garages, etc. It utilizes ultrasound sensors inthe front bumper and rear bumper(s) to meas-ure the distance to a vehicle or an object thatmay be close to the front or rear of your vehi-cle. An audible signal and symbols in theaudio system’s display indicate the distanceto the object.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will beincluded in the measurement of the availa-ble space behind the vehicle.
WARNING
Park Assist is an information system, NOT a safety system. This system is designedto be a supplementary aid when parkingthe vehicle. It is not, however, intended toreplace the driver's attention and judge-ment.
Function
Park assist button
The system is activated automatically when the vehicle is started. The indicator light in thebutton in the center console illuminates whenthe system is on.
• The front park assist system is active from the time the engine is started untilthe vehicle exceeds a speed of approxi-mately 6 mph (10 km/h). It is also activewhen the vehicle is backing up.
• Rear park assist is active when the engineis running and reverse gear has beenselected.
Activating/deactivatingThe system is activated automatically when the vehicle is started.
–Press the Park assist button on the center console to temporarily deactivate the sys-tem(s).
> The indicator light in the button will go
out when the system has been deacti- vated.
Park assist will be automatically reactivatedthe next time the engine is started, or if thebutton is pressed (the indicator light in thebutton will illuminate).
NOTE
Park assist is disengaged automatically when the parking brake is applied.

184* Option/accessory, for more information, see Introduction.
NOTE
• Rear park assist is deactivated auto- matically when towing a trailer if Volvogenuine trailer wiring is used. If a non-Volvo trailer hitch is being used, it maybe necessary to switch off the systemmanually, see page 182.
• The system will not detect highobjects, such as a loading dock, etc.
• Objects such as chains, thin shinypoles or low objects may temporarilynot be detected by the system. Thismay result in the pulsing tone unex-pectedly stopping instead of changingto a constant tone as the vehicleapproaches the object. In such cases,use caution when backing up or stopthe vehicle to help avoid damage.
Front park assist
G021424
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.
Faults in the system
If the information symbol illuminates andPark assist syst Service required is shown
on the information display, this indicates that the system is not functioning properly andhas been disengaged. Consult a trained andqualified Volvo service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning sig-nals that can be caused by external soundsources that use the same ultrasound fre-quencies as the system. This may includesuch things as the horns of other vehicles,wet tires on asphalt, pneumatic brakes,motorcycle exhaust pipes, etc. This doesnot indicate a fault in the system.

washers do not have facilities for washing the 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, wax-ing may be beneficial.
• Before applying polish or wax the vehiclemust 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 the bodywork 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).
CAUTION
Volvo does not recommend the use of long-life or durable paint protection coat-ings, some of which may claim to preventpitting, fading, oxidation, etc. These coat-ings have not been tested by Volvo forcompatibility with your vehicle's clear coat.Some of them may cause the clear coat tosoften, crack, or cloud. Damage caused byapplication of paint protection coatingsmay not be covered under your vehicle'spaint warranty.
Cleaning the interior
Only use cleaning agents and car care prod- ucts recommended by Volvo. Clean regularlyand follow the instructions included with thecar care product.
Upholstery care
FabricClean with soapy water or a detergent. For more difficult spots caused by oil, ice cream,shoe polish, grease, etc., use a clothing/
