160* Option/accessory, for more information, see Introduction.
Front/rear park assist
The park assist system is designed to assist you when driving into parking spaces,garages, etc. It utilizes four ultrasound sen-sors located in one or both bumpers to meas-ure the distance to a vehicle, object, or a per-son who may be close to the front or rear ofyour vehicle. Park assist is available in two versions:
• Rear bumper only
• Front and rear bumpers
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
The system is activated automatically when the vehicle is started. The indicator light in thebutton in the center console illuminates. • The front park assist system is active from the time the engine is started untilthe vehicle exceeds a speed of approxi-mately 10 mph (15 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.
Rear park assistThe distance monitored behind the vehicle is approximately 5 ft (1.5 m). The signal comesfrom the rear speakers. The system must be deactivated when towing a trailer, carrying bicycles in a rear-mountedcarrier, etc, which could trigger the rear parkassist system's sensors.
NOTE
Rear park assist is deactivated automati- cally when towing a trailer if Volvo genuinetrailer wiring is used.
Front park assistThe 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 auxili- ary headlights and front park assist sincethese lights could trigger the system'ssensors.
Activating/deactivating park assist
The system is activated automatically when the vehicle is started.
• Press the Park assist button on the center console (see page 65) to temporarilydeactivate the system(s). The indicatorlight in the button will go out when thesystem has been deactivated.
• Park assist will be automatically reactiva-ted the next time the engine is started, orif the button is pressed (the indicator lightin the button will illuminate).

* Option/accessory, for more information, see Introduction.161
NOTE
• Front park assist is disengaged auto- matically when the parking brake isapplied.
• If the vehicle is equipped with frontand rear park assist, both systems willbe deactivated by pressing the button.
Audible signals from the park assist system
The Park Assist system uses an intermittent tone that pulses faster as you come close toan object, and becomes constant when youare within approximately 1 ft (30 cm) of anobject in front of or behind the vehicle. If thevolume of another source from the audio sys-tem is high, this will be automatically lowered. If there are objects within this distance both behind and in front of the vehicle, the signalalternates between front and rear speakers.
Faults in the system
If the yellow warning symbol illu- minates and PARK ASSIST
SERVICE REQUIRED is shown
on the information display, this indicates that the system is not
functioning properly and has been disen-gaged. Consult a trained and qualified Volvoservice 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.
Cleaning the sensors
G026946
Park assist sensors The sensors must be cleaned regularly to ensure that they work properly. Clean themwith water and a suitable car washing deter-gent. 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.

Points to keep in mind when towing a trailer
•When towing trailers
without brakes, the
maximum permissible trailer weight is 1,700 lbs (750 kg).
• If necessary, redistribute the weight ofany cargo in the trailer to avoid excessiveweight on the trailer hitch.
• The maximum trailer weight listed in thetable for All Wheel Drive models,5,000 lbs (2250 kg) is only applicablewhen there are not more than two occu-pants in the vehicle, in the front seats,with a combined weight of 300 lbs(135 kg), with no other cargo in the vehi-cle.
• The maximum weight listed for FrontWheel Drive models, 4,000 lbs (1800 kg)is only applicable when there are notmore than four occupants in the vehicle,in the front seats and second row ofseats, with a combined weight of 600 lbs(270 kg), with no other cargo in the vehi-cle.
• Vehicles used for towing a trailer on aregular basis, or for long-distance high-way towing should be equipped with anautomatic transmission oil cooler andVolvo's automatic self-leveling system forthe rear suspension. Consult your Volvoretailer. •
Volvo recommends the use of Volvotrailer hitches that are specially designedfor the vehicle.
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
• Increase tire pressure to recommendedfull inflation pressure. See chapter"Wheels and tires."
• When your vehicle is new, avoid towingheavy trailers during the first 620 miles(1,000 km).
• Engine and transmission are subject toincreased loads. Therefore, engine cool-ant temperature should be closelywatched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range.
• If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations). •
Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• Remove the ball and drawbar assemblywhen the hitch is not being used.
• Volvo recommends the use of syntheticengine oil when towing a trailer over longdistances or in mountainous areas.
NOTE
•When parking the vehicle with a trailer on a hill, apply the parking brakebefore putting the gear selector in
P.
When starting on a hill, put the gearselector in D before releasing the park-
ing brake. Always follow the trailermanufacturer's recommendations forwheel chocking.
• If you use the manual (Geartronic) shiftpositions while towing a trailer, makesure the gear you select does not puttoo much strain on the engine (usingtoo high a gear).

WARNING
•Bumper-attached trailer hitches must not be used on Volvos, nor shouldsafety chains be attached to thebumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulicbrake system directly to the vehiclebrake system, nor a trailer's lightingsystem directly to the vehicle lightingsystem. Consult a trained and qualifiedVolvo service technician for correctinstallation.
• When towing a trailer, the trailer'ssafety wire must be correctly fastenedto the hole or hook provided in thetrailer hitch on the vehicle. The safetywire should never be fastened to orwound around the drawbar ball.
LevelingIf your vehicle is equipped with automatic lev- eling, the rear suspension always retains thecorrect ride height regardless of the load.
• The system adjusts the rear suspension to the correct level after the vehicle hasbeen driven a short distance.
• When the vehicle is stationary, the rearsuspension lowers, which is normal.
