Driver support systems
The vehicle is equipped with a number of driver support systems that can provide the driver withactive or passive assistance in various situations.
The system can, for example, help the driver maintain a set speed or a set time interval to thevehicle ahead, help prevent a collision by warningthe driver and applying the brakes, or assist thedriver while parking. Some of the systems are standard and others are options. This also varies from market to market.

Speed-dependent steering wheelresistance
Speed-dependent power steering increases the steering wheel resistance in pace with the vehi-cle's speed to give the driver an enhanced feel-ing of control and stability.
Steering may feel stiffer on highways. When parking and at low speeds, it will be easier tomove the steering wheel.
NOTE
In some situations, the power steering may become too hot and require temporary cool-ing – during such time the power steering willwork at reduced output and the steeringwheel may feel more difficult to move. In parallel with the temporarily reduced steer- ing assistance, the driver display shows amessage as well as a STEERING WHEELsymbol.

To temporarily deactivate Adaptive Cruise Control and put it in standby mode:
–Press the button on the steering wheel
(2). > The
symbol in the instrument panel
changes color from WHITE to GRAY and the set speed in the center of the speed-ometer will change from BEIGE to GRAY.
WARNING
• If Adaptive Cruise Control is in standby mode, the driver must intervene and regu-late both speed and distance to the vehicleahead.
• If the vehicle comes too close to a vehicleahead when Adaptive Cruise Control is instandby mode, the driver is instead warnedof the short distance by the Distance Alertfunction.
Standby mode due to action by the driver
Adaptive Cruise Control will be temporarily deac- tivated and put in standby mode if:
• the brakes are applied.
• the gear selector is moved to
N
• the vehicle is driven faster than the setspeed for more than 1 minute Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic standby mode
Adaptive Cruise Control is dependent on other systems, such as Electronic Stability Control (ESC 50
). If any of these other systems stops
working, Adaptive Cruise Control will automati- cally switch off.
WARNING
With automatic standby mode, the driver is warned by an acoustic signal and a messageon the instrument panel. • The driver must then regulate vehicle speed, apply the brakes if necessary, andmaintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standbymode if: • your vehicle's speed goes below 5 km/h(3 mph) and ACC cannot determine if thevehicle ahead is stationary or if it is anotherobject, e.g. a speed bump.
• your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatACC no longer has a vehicle to follow. •
the driver opens the door.
• the driver unbuckles the seat belt.
• the engine speed (rpm) is too low/high.
• one or more of the wheels lose traction.
• the brake temperature is high.
• the parking brake is applied.
• the camera/radar sensor is covered by snowor heavy rain (the camera lens/radar wavesare blocked)

Limitations of passing assistancewith Adaptive Cruise Control
Passing assistance functionality may be reduced in certain situations.
WARNING
The driver should be aware that if conditions suddenly change when using Parking Assis-tance, the function may implement an unde-sired acceleration in certain conditions. Some situations should be avoided, e.g. if: • the vehicle is approaching an exit in the same direction as passing would normallyoccur
• the vehicle ahead slows before your vehi-cle has had time to switch to the passinglane
• traffic in the passing lane slows down
• a vehicle for right-hand traffic is driven ina country with left-hand traffic (or viceversa).
Situations of this type can be avoided by tempo- rarily putting ACC 53
in standby mode.

Switching target vehicles withAdaptive Cruise Control
At certain speeds, models with automatic trans- missions and Adaptive Cruise Control (ACC 54
)
can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When Adaptive Cruise Control is actively follow- ing another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a moving vehicle to a stationary vehicle, Adaptive CruiseControl will brake for the stationary vehicle.
WARNING
When Adaptive Cruise Control follows another vehicle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle – from a moving vehicle to a stationary one – Adaptive Cruise Control will ignore the stationary vehi-
cle and instead accelerate to the stored speed. • The driver must then intervene and apply the brakes.
Automatic standby mode when switching
targets
Adaptive Cruise Control will be disabled and go into standby mode:
• if your vehicle's speed goes below 5 km/h(3 mph) and Adaptive Cruise Control cannotdetermine if the target object is a stationaryvehicle or another object, e.g. a speed bump.
• if your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns so thatAdaptive Cruise Control no longer has a vehi-cle to follow.

Automatic braking with AdaptiveCruise Control The Adaptive cruise control (ACC 55
) has a spe-
cial brake function in slow traffic and while sta- tionary.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is stopped for less thanapprox. 3 seconds. If it takes more than 3 sec-onds for the vehicle ahead to begin moving again,Adaptive Cruise Control will go into standbymode and the Auto-hold brake function will acti-vate.
–Adaptive Cruise Control can be reactivated in one of the following ways:
• Pressing the
button on the steering
wheel keypad.
• Pressing the accelerator pedal.
> Adaptive Cruise Control will resume fol- lowing the vehicle ahead if it begins to move within approx. 6 seconds.
NOTE
ACC can keep the vehicle stationary for no more than 5 minutes – after that time theparking brake is applied and Adaptive CruiseControl is deactivated. The parking brake must be released before Adaptive Cruise Control can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, Auto-hold will be deactivated when the vehicle is at a standstill and AdaptiveCruise Control will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehicle sta-tionary. This can occur if:
• the driver depresses the brake pedal
• the parking brake is applied
• the gear selector is moved to the
P
, N
or R
positions
• the driver puts Adaptive Cruise Control in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if Adaptive Cruise Control is keepingthe vehicle stationary using the brakes and:
• the driver opens the door or unbuckleshis/her seat belt
• ACC has kept the vehicle at a standstill formore than approx. 5 minutes
• the brakes overheat
• the driver switches off the engine manually.

Pilot Assist limitations
Pilot Assist functionality may be reduced in cer- tain situations.
Pilot Assist is a driver support function designed to simplify driving and assist the driver in manysituations. However, the driver is always responsi-ble for maintaining a suitable distance to vehiclesor objects around it and ensuring that the vehicleis correctly positioned in the traffic lane.
WARNING
In some situations, Pilot Assist may have trou- ble helping the driver properly or may bedeactivated automatically – we advise againstusing Pilot Assist in such cases. Examples ofsuch situations include:
• the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits orwhen there are multiple sets of markings.
• edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
• the lane is narrow or winding.
• the lane contains ridges or holes.
• weather conditions are poor, e.g. rain,snow or fog or slush or reduced visibilitywith poor light conditions, backlighting,wet road surface, etc.
The driver should also note that Pilot Assist has the following limitations: • High curbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane mark-ings, with a subsequent risk of contactbetween the vehicle and such obstacles.

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.
