Park Assist front, rear and sides
Park Assist has different parameters depending on which part of the vehicle is approaching anobstacle.
Back
Note: This illustration is general and details may vary depending on model.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored begins approx. 1.5 meters (5 feet) behind the vehicle. The rear sensors will be automatically deactivated if the vehicle is backing up with a trailer attached.
NOTE
When reversing with e.g. a trailer or bike car- rier on the trailer hitch – without Volvo originaltrailer cables – the Parking Assist system mayhave to be turned off manually to prevent thesensors from reacting to these.
Side sensors
Park Assist's side sensors are automatically acti- vated when the engine is started. They are activeat speeds below 10 km/h (6 mph). The distance monitored begins approx. 30 cm (1 ft) from the sides. The audible signal for obsta-cles along the sides of the vehicle is emittedfrom the side speakers.
Front camera
Note: This illustration is general and details may vary depending on model.
Park Assist's front sensors are automatically acti- vated when the engine is started. The front sen-sors are active at speeds below 10 km/h(6 mph). The distance monitored begins approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivated when the parking brake is applied or when P
is selected on vehicles with automatic trans- mission.

CAUTION
Objects such as chains, thin and glossy poles or low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected. The sensors cannot detect high objects, such as protruding ramps.
• In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable in such situations.
CAUTION
In some circumstances, the Park Assist Sys- tem may produce false warnings due to exter-nal sound sources with the same ultrasonicfrequencies as those the system works with. Examples of such sources are horns, wet tires on asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with the vehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.

Park Assist Pilot * limitations
Park Assist Pilot PAP 126
may not be able to
detect all conditions in all situations and func- tionality may therefore be limited.WARNING
• The PAP function is supplementary driver support intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
• Pay particular attention to people andanimals near the vehicle.
• Bear in mind that the front end of thevehicle may swing out towards oncomingtraffic during the parking maneuver.
• Objects situated higher than the detec-tion area of the sensors are not includedwhen the parking maneuver is calculated,which could cause PAP to swing into theparking space too early. Such parkingspaces should be avoided for this reason.
• PAP is not a substitute for the driver'sattention 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.
The driver should be aware of the following limi-tations for Park Assist Pilot:
The parking sequence is cancelledA parking sequence will be cancelled if:
• the driver moves the steering wheel
• the vehicle's speed exceeds 7 km/h (4 mph)
• the driver taps
Cancel in the center display
• when the anti-lock brakes or the Electronic stability control are engaged - e.g. when awheel loses grip on a slippery road
• when the power steering works at reduced power - e.g. during cooling due to overheat- ing (see section "Speed-dependent steeringforce").
A message in the center display will explain whythe parking sequence was cancelled.
CAUTION
Under certain circumstances, PAP may not be able to find parking spaces – one reason maybe that the sensors are disrupted by externalsound sources that emit the same ultrasonicfrequencies that the system works with. Examples of such sources include horns, wet tires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.

Automatic car washes The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easier toclean because dirt does not attach as strongly. Italso reduces the risk of scratches and keeps thevehicle looking new.
Automatic car washesAn automatic car wash is a fast and easy way to keep your vehicle clean, but it does not reach allareas of the vehicle. For best results, Volvo rec-ommends hand washing your vehicle or supple-menting automatic car washes with a hand wash.
NOTE
Volvo recommends not washing the vehicle in an automatic car wash during the first fewmonths; the paintwork on new vehicles takessome time to fully harden.
CAUTION
Before driving the vehicle into a car wash, deactivate the Automatic Braking when Sta-tionary and Automatic Parking Brake Applica-tion functions. If the functions are not deacti-vated, the brake system will seize when thevehicle is stationary and the vehicle will not beable to roll.
CAUTION
For automatic car washes in which the vehicle is pulled forward on rolling wheels:
1. Before washing the vehicle, make surethat the automatic rain sensor is deacti- vated. If it is not deactivated and inadver-tently starts, the wiper arms could bedamaged.
2. To help prevent damage from the auto- matic car wash machinery, make surethat the door mirrors are folded in, anten-nas retracted or removed, and any auxili-ary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the switch in the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis-play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.Hold the knob in position for at least2 seconds.
The vehicle is now ready for the automatic carwash.
