WARNING
•Keep the following points in mind with respect to the OWS system. Failure tofollow these instructions could adverselyaffect the system's function and result inserious injury to the occupant of the frontpassenger's seat:
• The full weight of the front seat passen-ger should always be on the seat cushion.The passenger should never lift him/herself off the seat cushion using thearmrest in the door or the center console,by pressing the feet on the floor, by sit-ting on the edge of the seat cushion, orby pressing against the backrest in a waythat reduces pressure on the seat cush-ion. This could cause OWS to disable thefront, passenger's side airbag.
WARNING
•Do not place any type of object on the front passenger's seat in such a way thatjamming, pressing, or squeezing occursbetween the object and the front seat,other than as a direct result of the correctuse of the Automatic Locking Retractor/Emergency Locking Retractor (ALR/ELR)seat belt.
• No objects should be placed under thefront passenger's seat. This could inter-fere with the OWS system's function.

Safety mode As a safety precaution after a collision, the func- tionality of some of the vehicle's systems may bereduced.
If the vehicle has been involved in a collision, the text Safety mode may appear in the information
display.
NOTE
This text can only be shown if the display is undamaged and the vehicle's electrical sys-tem is intact.
Safety mode is a feature that is triggered if one or more of the safety systems such as the front/side airbags inflatable curtain, etc., or one ormore of the seat belt pretensioners has deployed.The collision may have damaged an importantfunction in the vehicle, such as the fuel lines,sensors for one of the safety systems, the brakesystem, etc.

SAFETY
89
Rollover protection system Volvo'sRoll Stability Control (RSC) is a stability system designed to help minimize the risk of arollover in emergency maneuvers or if a skidshould occur.
RSC uses a gyroscopic sensor that registers the amount of change in the lateral angle at whichthe vehicle is leaning. Using this information, RSCcalculates the likelihood of a rollover. If there isan imminent risk of a rollover, the stability systemis activated, power to the engine is cut and thebrakes are applied to one or more of the wheelsuntil the vehicle regains stability.

LOADING AND STORAGE
* Option/accessory, for more information, see Introduction.207
Loading
The load carrying capacity of your vehicle is determined by factors such as the number ofpassengers, the amount of cargo, the weight ofany accessories that may be installed, etc.
Tailgate opening button on the lighting panel
Open the tailgate by pressing the button on the lighting panel, pressing the
button on the
remote key or by using the optional foot move- ment sensor under the rear bumper.
Loading recommendations
• Load objects in the cargo compartment against the backrest whenever possible.
• If the backrests of the second row seats arefolded down, they should not be in contactthe front seat backrests. This could impede the function of the Whiplash ProtectionSystem (WHIPS).
• Unstable loads can be secured to the loadanchoring eyelets with straps or web lash-ings to help keep them from shifting.
• Stop the engine and apply the parking brakewhen loading or unloading long objects. Thegear selector can be knocked out of positionby long loads, which could set the vehicle inmotion.
WARNING
•
Stop the engine, put the gear selector in P
, and apply the parking brake when
loading or unloading long objects.
• The vehicle's driving characteristics may change depending on the weight and dis-tribution 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 should notbe loaded to a level higher than 2 in.(5 cm) below the upper edge of the rearside windows. Objects placed higher thanthis level could impede the function ofthe Inflatable Curtain.
WARNING
•
Cover sharp edges on long loads to help prevent injury to occupants. Secure theload to help prevent shifting during sud-den stops.
• Always secure large and heavy objectswith a seat belt or cargo retaining straps.
• Always secure the load to help prevent itfrom moving in the event of sudden stops.
• Switch off the engine, apply the parking brake and put the gear selector in
P
when loading and unloading the vehicle.
Raising/lowering the rear-end of the vehicle *
Using the buttons on the read edge of the cargo compartment, the rear-end of the vehicle (thelevel of the cargo compartment floor) can beraised or lowered for easier loading or to make attaching a trailer 1
simpler.
1 An accessory trailer hitch can be purchased from a Volvo retailer.

Adaptive Cruise Control (ACC) *
ACC is an optional system designed to assist the driver by maintaining a set speed or a settime interval to the vehicle ahead.
The driver sets that desired speed and time inter- val to the vehicle ahead. When the camera andradar sensor detects a slower moving vehicleahead, your vehicle's speed is automaticallyadapted. When there are no longer slower mov-ing vehicles ahead, your vehicle will accelerate toresume the set speed. ACC is designed to follow a vehicle ahead in the same lane and maintain a time interval to thatvehicle set by the driver. If the radar sensor doesnot detect a vehicle ahead, ACC will insteadmaintain the speed set by the driver. ACC is designed to smoothly regulate speed. However, the driver must apply the brakes in sit-uations that require immediate braking. Thisapplies when there are great differences inspeed between vehicles, or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall. Adaptive Cruise Control can follow another vehi- cle from a standstill up to 125 mph (200 km/h).Always observe posted speed limits.
WARNING
• It is advisable to read through all of the related articles pertaining to ACC (seethe list at the end of this article).
• Adaptive Cruise Control cannot cover alldriving situations and traffic, weather androad conditions.
• 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.
OverviewThe distance to the vehicle ahead (in the same lane) is monitored by a radar sensor. Your vehi-cle's speed is regulated by accelerating andbraking. The brakes may emit a sound when theyare being modulated by the adaptive cruise con-trol system. This is normal.
WARNING
•
Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible for applying the brakes if thesystem does not detect another vehicle.
• Adaptive Cruise Control does not react topeople or animals, or small vehicles suchas bicycles and motorcycles. It also doesnot react to slow moving, parked orapproaching vehicles, or stationaryobjects.
• Do not use Adaptive Cruise Control indemanding driving conditions such as citydriving or other heavy traffic situations, inslippery conditions, when there is a greatdeal of water or slush on the road, duringheavy rain or snow, in poor visibility, onwinding roads or on highway on- or off-ramps.

Function buttons and symbols
–Press the button (2).
> The
symbol in the instrument panel
will change colors from WHITE to GRAY and the set speed in the center of thespeedometer will change from BEIGE toGRAY.
Standby mode due to action by the driverACC is temporarily deactivated and put in standby mode if:
• the brakes are applied
• The gear selector is moved to
N
• the vehicle is driven faster than the set speed for more than 1 minute. In these cases, the driver will have to regulate the vehicle's speed. A temporary increase in speed, such as when passing another vehicle, does not affect the ACCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.
Automatic standby modeACC interacts with other systems, such as Electronic Stability Control. If any of these othersystems are not functioning properly, ACC willturn off automatically.
WARNING
If this happens, the driver will be alerted by an audible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
ACC switches automatically to standby mode if: • the vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determineif the vehicle ahead is stationary or is anobject such as a speed bump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow
• the driver opens the door
• the driver unbuckles the seat belt •
engine speed (rpm) is too high/low
• the wheels lose traction
• the parking brake is applied
• the stability system's
ESC Sport Mode is
activated
• the
Off Road drive mode is selected
• The radar sensor is covered by e.g., wet snow or if heavy rain interferes with radar waves
Reactivating ACC from standby modeTo reactivate ACC after it has temporarily been put in standby mode:
–Press the button (1).
> The vehicle will then return to the most
recently set speed .

WARNING
•Pilot Assist is designed to be a supple- mentary driving aid and cannot cover alldriving situations, traffic, weather and/orroad conditions.
• The driver should be familiar with all ofthe information in this article regardingPilot Assist, including its limitations.
• Pilot Assist is not intended to replace thedriver's attention and judgement.
• Pilot Assist must only be used wherethere are clearly visible traffic lane sidemarker lines on both sides of the currenttraffic lane. In other circumstances thereis an increased risk of collision with sur-rounding obstacles that are not detectedby the system.
• The driver is always responsible for steer-ing the vehicle and maintaining a suitablespeed and distance to the vehicle aheadand must intervene if necessary, even ifPilot Assist is being used.
Pilot Assist is designed to regulate speed smoothly but in situations calling for fast braking,the driver must apply the brakes. This applies tosituations where there are considerable differen-ces in speed or if the vehicle ahead brakes sud-denly. Due to the limitations of the camera andradar sensor, the system may apply the brakes inyour vehicle suddenly or not at all. The default speed for Pilot Assist is preset toapprox. 30 mph (50 km/h) and cannot bechanged. If the vehicle ahead increases speed toover 30 mph (50 km/h) and pulls away from yourvehicle, Pilot Assist will go into standby mode.
NOTE
•
Pilot Assist maintenance should only be carried out by a trained and qualifiedVolvo service technician.
• Pilot Assist regulates your vehicle'sspeed using the accelerator pedal andthe brakes. Please be aware that theremay be a faint sound from the brakeswhen the system is using them.
WARNING
•Pilot Assist does not react to people or animals, or small vehicles such as bicy-cles and motorcycles. It also does notreact to low trailers, slow moving, parkedor approaching vehicles, or stationaryobjects.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in slipperyconditions, when there is a great deal ofwater or slush on the road, during heavyrain or snow, in poor visibility, on windingroads or on highway on- or off-ramps.
