Deactivating/reactivating the cruise control The cruise control (Cruise Control - CC) can be temporarily deactivated so that it is set in thestandby mode and can be reactivated later.
NOTE: The illustration is schematic - details may vary depending on car model.
Deactivate Cruise Control and set in
standby mode
–Press the steering wheel button (2).
> The speed limit markings and symbols in the driver display change colour from WHITE to GREY — Cruise Control is nowtemporarily deactivated and the driver cantemporarily exceed the set speed.
Standby mode on driver intervention
The cruise control is temporarily deactivated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position
• the clutch pedal is held depressed for longerthan 1 minute
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
The driver must then control the speed himself/herself. A temporary increase in speed with the accelera- tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released.
Automatic standby mode
Cruise control is temporarily disengaged and set in standby mode if:
• wheels lose traction
• engine speed is too low/high
• brake temperature is too high
• speed falls below 30 km/h (20 mph).
The driver must then control the speed himself/herself.

Deactivating/activating the adaptive cruise control *
The adaptive cruise control (Adaptive Cruise Control - ACC) can be temporarily deactivatedso that it is set in the standby mode and canlater be reactivated.
Deactivate Adaptive Cruise Control and set it in standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
To temporarily switch off Adaptive Cruise Control and set it in standby mode:
–Press the steering wheel button (2).
> The
symbol on the driver display
changes colour from WHITE to GREY and the stored speed in the centre of thespeedometer changes from BEIGE toGREY. In standby mode, the driver must him/herselfcontrol both speed and distance. When the adaptive cruise control is in standby mode and the car drives too close to a vehicleahead, the driver is warned about the short dis-tance by the Distance Warning function instead(see reference to the heading "Distance Warn-ing" at the end of this section).
Standby mode on driver intervention
The adaptive cruise control is temporarily deacti- vated and set in standby mode if:
• the foot brake is used
• the gear selector is moved to
N position.
• the driver maintains a speed higher than thestored speed for longer than 1 minute.
• the clutch pedal is depressed for approx. 1minute - applies to cars with manual gearbox.
In this situation, the driver must intervene andadapt the speed and distance to the vehicleahead. A temporary increase in speed with the accelera- tor pedal, e.g. during overtaking, does not affectthe setting - the car returns to the last storedspeed when the accelerator pedal is released.
Automatic standby mode
Adaptive cruise control is dependent on other systems, e.g. stability control/anti-skid ESC. If anyof these systems stops working, adaptive cruisecontrol is switched off automatically. In the event of automatic deactivation a signal willsound and a message is shown in the driver dis-play. The driver must then intervene and adaptthe speed and distance to the vehicle ahead. Automatic deactivation may occur if:
• the speed is below 5 km/h (3 mph) and ACC is uncertain whether the vehicle ahead is astationary vehicle or an object, such as aspeed bump.
• the speed is below 5 km/h (3 mph) and thevehicle ahead turns off so that ACC nolonger has a vehicle to follow.
• speed is reduced to below 30 km/h(20 mph) - only applies to cars with manualgearbox.
• the driver opens the door
• the driver takes off the seatbelt
• engine speed is too low/high
• wheels lose traction
• brake temperature is high
• the parking brake is applied
• the camera and radar unit is covered by e.g.snow or heavy rainfall (camera lens/radiowaves are blocked).

Level control * and shock absorption
Level control and shock absorption are regula- ted automatically in the car.
With rear level control, the car maintains the same height at the rear regardless of load. Levelcontrol can also occur even after the car hasbeen parked.
Shock absorption (Four-C)The shock absorption is adapted according to theselected drive mode and according to the speedof the car. Shock absorption is normally set forthe best possible comfort and is regulated con-tinuously depending on the road surface, thecar's acceleration, braking and cornering.
Settings for level control
Deactivation of air suspension and level control
In certain cases, the function must be deacti- vated, e.g. before the car is raised with a jack *.
The difference in level created by raising the car with a jack can otherwise cause problems for theair suspension. Deactivating the function via the centre display:1. Press
Settings in the top view.
2. Press
My CarSuspension .
3. Select
Disable Leveling Control.
Change the damping level 11
Cars with active chassis (Four-C) and without the drive mode function
* can adjust the shock
absorption level via the centre display: 1. Press
Settings in the top view.
2. Tap on
My CarDrive ModeSuspension Control and select the level.
During transportDuring transport of the car on a ferry, train or truck, the car must be lashed around the tyresand not around other parts of the chassis.Changes in the air suspension may occur duringtransport, which could affect the lashing nega-tively.

All-wheel drive
*
All-wheel drive, AWD (All Wheel Drive), means that the car is driving all four wheels at the sametime, which improves traction.
To achieve the best possible traction and prevent wheel spin the motive force is distributed auto-matically to the wheels with the best grip. Thesystem continuously calculates the need for tor-que to the rear wheels, and can immediatelyredistribute up to half of the motor's torque to therear wheels. All-wheel drive also has a stabilising effect at higher speeds. Under normal driving conditions,the majority of power is transmitted to the frontwheels. When stationary, the all-wheel drive isalways engaged in preparation for maximum trac-tion during acceleration. All-wheel drive characteristics vary depending on the selected drive mode *.

Parking on a hill
WARNING
Always use the parking brake when parking on an inclined surface. Engaging a gear or the automatic transmission's P position is not suf-
ficient to hold the car stationary in all situa- tions.
If the car is parked facing uphill: • Turn the wheels
away from the kerb.
If the car is parked facing downhill:
• Turn the wheels
towards the kerb.
Heavy load uphill
A heavy load, such as a trailer, can cause the car to roll backward when the parking brake isreleased automatically on a steep incline. Avoid this by pulling the control upwards while drivingthe car away. Release the control when theengine achieves traction.
Settings for parking brake
Automatic activation of the parking brake isselected via the centre display. Automatic activation when the car is switched off:1.
Press
Settings in the top view.
2. Press
My CarParking Brake and
Suspension and deselect/select the func-
tion Auto Activate Parking Brake.
Related information
• Parking brake (p. 409)
• In the event of a fault in the parking brake (p. 411)
• Automatic braking when stationary (p. 412)
In the event of a fault in the parking brake
Contact an authorised Volvo workshop if it is not possible to release or apply the parking brakeafter several attempts.
An acoustic warning signal sounds when driving with the parking brake applied. If the car has to be parked before a possible fault is rectified then the wheels must be turned as ifparking on a hill and the gear selector must be in position P, or engage first gear if the car has a
manual gearbox.
Low battery voltageIf the battery voltage is too low then the parking brake can neither be released nor applied. Con-nect a donor battery if the battery voltage is toolow.
Replacing the brake liningsThe rear brake linings must be replaced at aworkshop due to the design of the electrically-operated parking brake - an authorised Volvoworkshop is recommended.
