Adaptive Cruise Control – introductionACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead. It is primarilyintended for use on long straight roads in steadytraffic, such as on highways and other mainroads.
When the driver has set the desired speed and the time interval to the vehicle ahead, ACC func-tions as follows:
• If there are no other vehicles in the laneahead of you, your vehicle will travel at theset speed.
• If ACC's radar sensor detects a slower mov-ing vehicle in the lane ahead, the system willadapt your vehicle's speed to help maintainthe set time interval to the vehicle ahead.When there are no longer slower movingvehicles ahead, your vehicle will accelerate toresume the set speed.
If ACC is switched off completely or in standbymode and your vehicle comes too close toanother vehicle ahead, the driver will be warnedby the Distance Alert system (see Distance Alert– introduction (p. 191)).
WARNING
• Adaptive Cruise Control cannot cover all driving situations and traffic, weather androad conditions. The "Function" sectionprovides information about limitations thatthe driver must be aware of before usingthis feature.
• This system is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance and speedand must intervene if Adaptive CruiseControl does not maintain a suitablespeed or suitable distance to the vehicleahead.
• Maintenance of ACC components mayonly be performed by a trained and quali-fied Volvo technician.

Adaptive Cruise Control – limitationsThe ACC cannot cover all driving situations and traffic, weather and road conditions.
Situations where ACC may not function optimally
WARNING
• The radar sensor has a limited field of vision. In some situations it may detect avehicle later than expected or not detectother vehicles at all.
• If ACC is not functioning properly, cruisecontrol will also be disabled.
Radar sensor's field of vision (shown in pink)
In certain situations, the radar sensor cannot detect vehicles at close quarters, for examplea vehicle that suddenly enters the lanebetween your vehicle and the target vehicle.
Small vehicles, such as motorcycles, or vehi- cles not driving in the center of the lane mayremain undetected.
In curves, the radar sensor may detect the wrong vehicle or lose sight of the target vehi-cle.

WARNING
•Pedestrian and Cyclist Detection with Full Auto Brake does not work in all driving,traffic, weather and road conditions. Itdoes not react to vehicles not traveling inthe same direction as your vehicle.
• Pedestrian and Cyclist Detection with FullAuto Brake does not react to animals.
• Warnings are only provided when the riskof collision is high. The "Function" sectionprovides information about limitations thatthe driver must be aware of before usingCollision Warning.
• Pedestrian and Cyclist Detection with FullAuto Brake will not provide a warning orbrake the vehicle for pedestrians orcyclists at speeds above 50 mph(80 km/h).
WARNING
•
Pedestrian and Cyclist Detection with Full Auto Brake will not provide a warning orbrake the vehicle for pedestrians in dark-ness or in tunnels, even if there is streetlighting in the area.
• The auto-brake function can help preventa collision or reduce the speed at impactbut the driver should always apply thebrakes for the best possible brakingeffect, even if auto-brake is actively apply-ing the brakes.
• Never wait for a collision warning. Thissystem is designed to be a supplemen-tary driving aid. It is not, however,intended to replace the driver's attentionand judgement. The driver is responsiblefor maintaining a safe distance andspeed, even when the collision warningsystem is in use.
• Maintenance of the Pedestrian andCyclist Detection with Full Auto Brakesystem's components must only be per-formed by a trained and qualified Volvotechnician.

Park Assist Pilot (PAP) * – limitations
The PAP parking procedure will be cancelled if.
• The vehicle's speed goes above approxi- mately 4 mph 7 km/h
• The driver moves the steering wheel
• If the stability or ABS systems are activated(e.g., if a wheel starts to spin because of aslippery road surface
If the system has been switched off, this will beindicated by a text message in the instrumentpanel.
NOTE
• PAP will not function correctly if its sen- sors are obstructed by dirt, snow, etc.
• In certain situations, PAP may not be ableto measure a parking space. This couldbe due to external sources of sound (e.g.,a vehicle's horn, tires on wet asphalt,pneumatic brakes, noise from a motorcy-cle's exhaust, etc.) emitting ultrasoundusing approximately the same frequen-cies as PAP.
Information to keep in mind
PAP is only intended to provide parallel parking assistance but may not be able to function fully inall situations. •
PAP's function is based on the way that thevehicles are parked behind and in front ofyour parking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims couldbe damaged by the curb during the parkingprocedure.
• PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with curved or irregular curbs. Be surethat your vehicle is parallel to the curb whenPAP measures the parking space.
• PAP may not be able to provide parkingassistance on narrow streets due to lack ofspace to maneuver the vehicle. In situationslike this, it may help to drive as close to theside of the road as possible where the park-ing space is located.
• Use only approved tires with the correct infla-tion pressure because this affects PAP'scapacity to provide parking assistance.Changing to a different approved tire sizemay affect PAP's parameters. Consult atrained and qualified Volvo service technician.
• Heavy rain or snow may inhibit PAP'scapacity to correctly measure a parkingspace.
• Do not use PAP if snow chains or a tempo-rary spare tire is being used.
• Do not use PAP if there are any objects pro-truding from the vehicle.
WARNING
• The front end of your vehicle may turn out toward oncoming traffic during the park-ing procedure.
• Objects located above the parking sen-sors' field of vision are not included whenPAP measures a parking space. For thisreason, PAP may turn into the parkingspace too soon. Avoid parking spaces ofthis type.
• The driver is always responsible for deter-mining if PAP has selected a suitableparking space.
Maintenance

CTA's blind area
CTA's "field of vision"
In angled parking spaces, CTA may be "blind" on one side
However, as you back your vehicle out of a park- ing space, CTA's "field of vision" expands. Examples of other limitations include:
• Dirt, ice or snow obstructing the sensors mayreduce the system's function or make itimpossible to detect other vehicles orobjects.
• Do not attach tape, decals, etc., on the sur-face of the sensors (see the illustration in thefollowing "Maintenance" section).
• BLIS and CTA are deactivated if a trailer'swiring is connected to the vehicle's electricalsystem.

WARNING
Driving with the trunk open:
Driving with the
trunk open could lead to poisonous exhaust gases entering the passenger compartment. Ifthe trunk must be kept open for any reason,proceed as follows:
• Close the windows
• Set the ventilation system control to airflow to floor, windshield and side windowsand the blower control to its highest set-ting.
Handling and roadholdingAt the specified curb weight your vehicle has a tendency to understeer, which means that thesteering wheel has to be turned more than mightseem appropriate for the curvature of a bend.This ensures good stability and reduces the riskof rear wheel skid. Remember that these proper-ties can alter with the vehicle load. The heavierthe load in the trunk, the less the tendency toundersteer. • Vehicle load, tire design and inflation pres- sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so that capacity weight or maximum permissible axleloads are not exceeded.

Towing a trailer When towing a trailer, always observe the legal requirements of the state/province.
NOTE
For the maximum trailer and tongue weights recommended by Volvo, see Weights (p. 373)
•
All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure, see the tire inflation decal on thedriver's door opening.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.

STARTING AND DRIVING
286•
If the automatic transmission begins to over- heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy.
• It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
• When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.
CAUTION
The maximum trailer weights listed are only applicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.
