INTRODUCTION
* Option/accessory.19
8" instrument panel
The instrument panel displays information such as speed, an incoming phone call or the trackthat is currently playing. It is controlled using bothsteering wheel keypads.
Center display
Many of the vehicle's main functions are con- trolled from the center display, a touchscreen thatreacts to taps or other gestures. The number ofphysical buttons is thereby minimized. The screencan be operated with or without gloves. The center display is used to control e.g., the cli- mate and infotainment systems and to adjust the power seats*. The information shown here can be
dealt with by the driver or the front seat passen- ger.
Voice control system
The voice control system ena- bles the driver to operate cer-tain vehicle functions withoutremoving his/her hands fromthe steering wheel and itunderstands natural speech.Use voice commands to e.g.,
play a track on the infotainment system, make aphone call, raise the passenger compartmenttemperature or to read a text message.
For additional information about all of the func- tions/system, see the respective articles in theon-board owner's manual or the printed supple-ment.

Adapting brightness
The brightness of the graphics displayed in the HUD are also automatically adjusted according toambient lighting conditions. HUD brightness isalso affected by adjustments to the brightness ofthe other displays in the vehicle.
Power front seat * memory function
The position of the HUD can be stored in the power seat's memory function.
Replacing the windshieldVehicles with a head-up display have a specialtype of windshield meeting the requirements fordisplaying projected information. If the windshield has to be replaced, contact a trained and qualified Volvo service technician orauthorized workshop. The correct type of replace-ment windshield must be used for a head-up dis-play.
Calibrating the horizontal positionIf the windshield has been replaced, it may benecessary to calibrate the HUD's horizontal posi-tion. This means that the projected image willhave to be rotated clockwise or counterclockwise.To do so:
1. Pull down the center display's Top view and
tap
Settings. 2.
Select
My CarDisplaysHead-Up
Display Calibration.
3. Use the buttons on the right-side steering wheel keypad to calibrate the horizontal posi- tion.
Rotate counterclockwise
Rotate clockwise
Confirm
CleaningWipe the glass covering the HUD projection unit carefully with a clean and dry (or very slightlydamp if necessary) microfiber cloth. Never use strong stain removers. For difficult cleaning conditions, a special cleaning agent canbe purchased at a Volvo retailer.

DRIVER SUPPORT
* Option/accessory.

Driver support systems
The vehicle is equipped with a number of driver support systems that help provide the driver withactive/passive support.
Some of these systems are standard while others are optional and they are designed to e.g., helpthe driver maintain a set speed or a set distanceto a vehicle ahead, or warn the driver of a poten-tial collision situation and in certain cases applythe brakes if necessary. Certain optional systemscan also assist in various parking situations.

Adjustable steering force *
Steering force increases with the speed of the vehicle to give the driver an enhanced sense ofcontrol and stability. At low speed the vehicle iseasier to steer in order to facilitate parking, etc.
Changing the steering force levelTo change the level of steering force, see theinformation under the heading "individual" in arti-cle "Drive modes" for additional information. On models not equipped with the drive mode control in the center console, the selection ismade in the center display's Top view under:
SettingsMy CarDrive ModesSteering force
NOTE
•This steering force level menu function cannot be accessed when the vehicle isin motion.
• In certain situations, the power steeringfunction may become too hot and mustbe temporarily cooled. During cooling,power steering effect will be reduced andmore force may be necessary to turn thesteering wheel and a message will bedisplayed in the instrument panel.

STARTING AND DRIVING
* Option/accessory.
346
Starting and driving The vehicle is equipped with features that sup- plement its basic functions, such as shifting gears with steering wheel paddles * and the fuel-
conserving start/stop function.
The vehicle is equipped with an automatic trans- mission that also makes it possible to shift gearsmanually. Certain functions can also be used when the engine is not running, depending on the ignitionmode being used.

• Parking brake (p. 350)
Brakes The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
Brake systemIf one of the brake circuits is not functioning, more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect. If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function. The power brakes only function when the engine is running. If the power brakes are not working, considerably higher pressure will be required on the brakepedal to compensate for the lack of power assis-tance. This can happen for example when towingyour vehicle or if the engine is switched off whenthe vehicle is rolling. The brake pedal feels stifferthan usual. When the Hill Start Assist function is being used, it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface. When driving in very hilly areas or if the vehicle iscarrying a heavy load, manual gear shifting canbe used for engine braking to augment the brakes.
Hill Descent Control can also be used
on steep downgrades to increase the engine braking effect at low speeds.
Anti-lock Braking System ABS
The ABS system helps to improve vehicle control (stopping and steering) during severe brakingconditions by limiting brake lockup. When ABS is operating, there may be some vibration in the brake pedal, which is normal. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.

Towing recommendations
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
Towing your vehicle behind another vehicle
1. After securely attaching the towing line to both vehicles, put the gear selector in posi- tion N and release the parking brake.
2. Put the ignition in mode II by turning the
start knob to START (without depressing
the brake pedal) and hold it in this position
for approx. 4 seconds. Release the knob.
3. Put the gear selector in position N and
release the parking brake.
4. The towing vehicle can now begin driving.
5. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This will help prevent jar-ring movements of the vehicle being towed.
6. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• If the vehicle's battery is dead, an auxiliary battery will be necessary to provide cur-rent for releasing the electric parkingbrake and to move the gear selector from the
P position to N. If this is not possible,
use the shiftlock override procedure tomanually release the gear selector from P
and move it to N.
• Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable tow-ing speed.
• Maximum distance with front wheels onground: 50 miles (80 km).
• The vehicle should only be towed in theforward direction.
WARNING
• When the vehicle is being towed, the igni- tion should be in mode
II (in mode I, all of
the vehicle's airbags are deactivated).
• The remote key must remain inside the vehicle.
• The power brakes and power steering willnot function when the engine is not run-ning. Approximately 5 times more pres-sure will be required on the brake pedaland the steering wheel will be considera-bly harder to turn.
• The towing eyelets must not be used forpulling the vehicle out of a ditch or forany similar purpose involving severestrain.
