•
The gear selected is moved to
P,N or R
• The driver presses the
button to put
ACC in standby mode
The parking brake is applied
automatically
In certain situations, ACC will apply the park- ing brake in order to continue keeping thevehicle at a standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• DSTC is put in Sport mode (seepage 152)
• ACC has kept the vehicle at a standstillfor more than 2 minutes
• The engine has been switched off
• The brakes have overheated
The radar sensor and its limitations
In addition to being used by ACC, the radar sensor is also used by Distance Alert (seepage 169) and Collision Warning with FullAuto-brake and Pedestrian Detection (seepage 178). This sensor is designed to detectcars or larger vehicles driving in the samedirection as your vehicle, in the same lane.
WARNING
• If there is visible damage to the front grille or you suspect that the radarsensor may be damaged in any way,contact a trained and qualified Volvoservice technician as soon as possible.The radar sensor may only functionpartially (or not at all) if it is damagedor is not securely fastened in place.
• Accessories or other objects, such asextra headlights, must not be installedin front of the grille.
• Modification of the radar sensor couldmake its use illegal.
The radar sensor's capacity to detect vehi- cles ahead is impeded:
• if the radar sensor is obstructed and can- not detect other vehicles, for example inheavy rain, or if snow or other objects areobscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
• if the speed of vehicles ahead is signifi- cantly different from your own speed.
Situations where ACC may not function optimally
WARNING
•The radar sensor has a limited field of vision. In some situations it may detecta vehicle later than expected or notdetect other vehicles at all.
• If ACC is not functioning properly,cruise control will also be disabled.

Introduction
The load carrying capacity of your vehicle is determined by factors such as the number ofpassengers, the amount of cargo, the weightof any accessories that may be installed, etc. To increase loading space, the rear seat backrests can be folded down, see page 93. When loading the cargo area, keep the fol- lowing in mind:
• Load objects in the cargo area against the backrest whenever possible.
• Unstable loads can be secured to theload anchoring eyelets with straps or weblashings to help keep them from shifting.
• Stop the engine and apply the parkingbrake when loading or unloading longobjects. The gear selector can beknocked out of position by long loads,which could set the vehicle in motion.WARNING
•Stop the engine, put the gear selector in
P, and apply the parking brake
when loading or unloading longobjects.
• The vehicle's driving characteristicsmay change depending on the weightand distribution of the load.
• A 44-pound (20 kg) object produces aforce of 2,200 pounds (1,000 kg) in ahead-on collision at 30 mph (50 km/h).
• The cargo area and rear seat shouldnot be loaded to a level higher than2 in. (5 cm) below the upper edge ofthe rear side windows. Objects placedhigher than this level could impede thefunction of the Inflatable Curtain.

closed, it will stop
and move slightly in the opposite direc-tion.
Operating the tailgate manuallyThe power tailgate can be disconnected from the vehicle’s electrical system by quickly pull-ing the outer handle twice. The tailgate canthen be opened/closed manually.
Folding down the rear seat backrests
The rear seat backrests can be folded down for additional loading space, see page 95.
Load anchoring eyelets
The load anchoring eyelets on both sides of the vehicle are used to fasten straps, etc., tohelp anchor items in the cargo area.
WARNING
• Cover sharp edges on long loads to help prevent injury to occupants.Secure the load to help prevent shift-ing during sudden stops.
• Always secure large and heavy objectswith a seat belt or cargo retainingstraps.
• Always secure the load to help preventit from moving in the event of suddenstops.
• Switch off the engine, apply the park-ing brake and put the gear selector inP
when loading and unloading the
vehicle.
Cargo area floor rails and hooks
Load secured in upper and lower hooks The floor of the cargo compartment has rails on opposite sides of the vehicle equippedwith hooks for anchoring loads with straps,nets, etc.
Cleaning the railsDirt or other small objects that collect in therails can make moving, locking, unlocking,and removing the hooks more difficult.Objects can be removed from the rails with avacuum cleaner, and the rails can be cleanedwith a moist cloth.
