All Wheel Drive (AWD) 11
Your Volvo can be equipped with All Wheel Drive, which means that power is distributedautomatically between the front and rear wheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction. AWD reacts differently, depending on the drive mode * selected.

Suspension and leveling control
*
The leveling control system adjusts the suspen- sion and shock absorbers automatically to helpprovide good comfort and control while driving.Leveling can also be controlled manually tomake loading or getting in and out of the vehicleeasier.
Pneumatic suspension and shock absorbers
This system is linked to the selected drive mode and is adapted to the vehicle's speed. The pneu-matic suspension reduces the vehicle's groundclearance at higher speeds to reduce wind resis-tance and increase stability. The shock absorbersare normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface, acceleration, braking andcornering. A message will be displayed in the instrument panel when the suspension level is beingadjusted. The level cannot be adjusted if one of the side doors or the hood is open.
Suspension leveling settings
Easy entryThe vehicle can be lowered to entering and exit- ing easier. Select
SettingsVehicleEasy Entry/Exit
Control via the center display's Top view to lower
the vehicle when getting in or out. When the vehicle is parked and the engine is turned off, the level is lowered (if a side door isopened, the level adjustment will stop). When theengine is started and the vehicle begins to move,the level will be raised to the height set by theselected drive mode.

Wi-Fi connection to a workshop The time a vehicle is in a workshop for service or repairs can be reduced by transmitting trouble-shooting information as soon as the car reachesthe workshop. This is done most conveniently by selecting
Automatically connect when I arrive in the
center display's Settings menu.
Each time the vehicle slows down to a sufficiently low speed, it begins searching for a Wi-Fi net-work. If an authorized Volvo network (at a retaileror workshop) is found, a message will be dis-played or a pop-up window will open in the cen-ter display (this applies to manual connections,see the section "Manually connecting to a work-shop" below).
Automatically connecting to a workshop
Without driver confirmationThis is the most convenient way to transmit trou- ble-shooting data. The driver does not need toconfirm that the vehicle will establish a connec-tion. If the vehicle stops at a workshop and the engine is switched off using the start knob, a messagewill appear above the status bar in the center dis-play. The vehicle will be automatically connectedwhen the driver's door is opened if the driver does not tap the
Cancel button in the message.
To help prevent the driver from being disturbed by unwanted requests to connect (e.g., if the vehicle is often parked near a workshop with anauthorized Volvo network), the vehicle will switchto manual connection if the driver cancels a con-nection request twice within 5 days.
With driver confirmationWith this alternative, the driver must confirm a connection. If the vehicle stops at a workshop and the engine is switched off using the start knob, a pop-upwindow will open in the center display. The vehi-cle will be automatically connected when the driv- er's door is opened if the driver taps
Connect in
the pop-up window. If the driver does nothing or taps the pop-up window's
Abort button, no
attempt will be made to establish a connection.
NOTE
To help prevent the driver from being distur- bed by unwanted requests to connect (e.g., ifthe vehicle is often parked near a workshopwith an authorized Volvo network), the vehiclewill switch to manual connection if the drivercancels a connection request twice within5 days.
Manually connecting to a workshopManual connections are handled by the service technician.
Changing the way a connection is madeThe type of connection (manual or automatic)can be changed in the center display's Settingsmenu.
1. Pull down the center display's Top view and
tap

Start battery
The start (main) battery is used to power the starter motor and other electrical componentsand systems. The start battery should only be replaced by a trained and qualified Volvo service technician.
The vehicle has an alternating current generator. The start battery is called an Absorbed Glass Mat (AGM) 12-volt battery that is dimensioned foruse in vehicles with carbon dioxide-reducingfunctions such as Start/Stop and regenerativecharging, and to support the vehicle's variouselectrical systems and functions. The service life of a battery is affected by factors such as driving conditions/style, the number ofstarts, climate, etc. Extreme cold may also furtherdecrease the battery

• When replacing the start battery or support battery in a vehicle with Start/Stop, anAbsorbed Glass Mat (AGM) must be used.
• When replacing the start battery, a new bat-tery with the same specifications and dimen-sions must be used. The battery should onlybe replaced by a trained and qualified Volvoservice technician.

Support battery Vehicles equipped with Start/Stop are equipped with two 12-volt batteries.
In addition to a heavy-duty start battery, models with Start/Stop also have a support battery thatprovides extra current during the Start/Stopfunction's start sequence.
The support battery is located in a box next to the spring strut in the engine compartment
The following table shows the specifications for the support battery:
Current (V)12
Cold start capacity (Cold Cranking Amperes -CCA) (A)170
Dimensions, L×W×H in. (mm)5.9×3.5×5.1

• When replacing the start battery or support battery in a vehicle with Start/Stop, anAbsorbed Glass Mat (AGM) must be used.
• The greater the current consumption in thevehicle, the more the generator has to oper-ate and the battery is charged. This increasesfuel consumption.
• When the start battery's charge is below theminimum permitted level, the Start/Stopfunction will be disabled.
When the Start/Stop function is temporarily disa- bled due to high current consumption:
• The engine will auto-start, even if the brake pedal is depressed.
The support battery does not normally required more service than the start battery. If questionsarise, consult a Volvo retailer or trained and quali-fied Volvo service technician.
CAUTION
When connecting an external start battery or a battery charger, the Start/Stop function maybe temporarily disabled if the negative termi-nal on the vehicle's start battery is used toconnect an external start battery or a battery charger. Only the negative connection point
in the engine compartment may be used as a ground point.
NOTE
If the start battery is completely discharged and the vehicle has no normal electrical func-tions, and the engine is then started using anauxiliary battery or battery charger, theStart/Stop function will be activated. Theengine can then be auto-stopped but may notauto-start again due to an insufficient chargelevel in the start battery. To help ensure auto-start, the start battery should be charged first. At a temperature ofapprox. 60 °F (15 °C), the battery should becharged for at least 1 hour, preferably usingan external battery charger. At lower tempera-tures, the battery should be charged for3–4 hours. If a charger is not available, it is advisable to disable the Start/Stop function until the bat-tery is sufficiently recharged.
