Long-term storage of vehicles withhybrid batteries
To help minimize degradation of the hybrid bat-tery if the vehicle is not driven for a prolongedperiod (longer than 1 month) the hybrid batterycharge level should be kept at approx. 25%according to the gauge in the instrument panel.
Do as follows:
1. If the hybrid battery charge level is high, drivethe vehicle until the charge level is approxi-mately 25%. If the charge level is low, chargethe battery until the level reaches approxi-mately 25%.
2. If the vehicle is not driven for more than 6months or the hybrid battery's charge level isnoticeably below the 25% mark, charge thebattery to about 25% to help compensate forthe natural battery discharge that occurs inlong-term storage. Regularly check thecharge level using the gauge in the instru-ment display.

NOTE
Store the vehicle in as cool a location as pos-sible to minimize battery aging during long-term storage. In the summer, park the vehicleindoors or in a shady location, whichever iscooler.

Starting the vehicle
The vehicle can be started using the start knobin the tunnel console when the remote key is inthe passenger compartment.
Start knob in the tunnel console.

WARNING
Before starting:
Buckle your seat belt.
Adjust the seat, steering wheel and mir-rors.
Make sure you can fully depress thebrake pedal.
The remote key is not physically used to start theignition because the vehicle is equipped with thekeyless Passive Start system.
To start the vehicle:
1.The remote key must be inside the vehicle.For vehicles with Passive Start, the key mustbe in the front section of the passengercompartment. With the optional keyless lock-ing/unlocking function*, the key can be any-where in the vehicle.
2. Press and hold down the brake pedal1 as faras possible.
3. Turn the start knob clockwise and release.The control will automatically return to theoriginal position.
WARNING
Never use more than one inlay mat at atime on the driver's floor. If any other typeof floor mat is used, remove the originalmat from the driver's seat floor beforedriving. All types of mats must be securelyanchored in the attachment points in thefloor. Make sure the floor mat does notimpede the movement of the brake pedalor accelerator pedal in any way, as thiscould be a serious safety hazard.
Volvo's floor mats are specially manufac-tured for your vehicle. They must be prop-erly secured in the attachment points inthe floor to help ensure they cannot slideand become trapped under the pedals.
The starter motor will crank until the enginestarts or until overheating protection is triggered.
During normal start conditions, the vehicle's elec-tric motor will be prioritized and the gasolineengine will remain off. This means that once thestart knob is turned clockwise, the electric motorhas been "started" and the vehicle is ready to bedriven. The warning and information symbols inthe instrument panel will go out and the selectedtheme will be displayed to indicate that the elec-tric motor is activated.
1If the vehicle is moving, it is only necessary to turn the start knob clockwise to start the engine.

Ignition modes
The vehicle's ignition can be put in variousmodes (levels) to make different functions availa-ble.
To enable the use of a limited number of func-tions when the engine is not running, the ignitioncan be put in one of three different levels: 0, Iand II. These levels are referred to as "ignitionmodes" in the Owner's Manual.
The following table shows which functions areavailable in each ignition mode:
Mode Functions
0The odometer, clock and tem-
perature gauge are illuminatedA.
The power* seats can beadjusted.
The power windows can be used.
The center display is activated
and can be usedA.
The infotainment system can be
usedA.
In this mode, the functions are availa-ble for a limited time and then switchoff automatically.
IThe panoramic roof, power win-dows, 12-volt electrical socket inthe passenger compartment,Bluetooth, navigation, phone,blower and windshield wipers canbe used.
The power seats can be adjusted.
The 12-volt electrical socket* inthe trunk can be used.

Transmission
The transmission is part of the vehicle's driveline(power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis-sion and an electric motor for rear-wheel drive.The number of gears allows the engine's torqueand power band to be effectively utilized. Two ofthe gears are overdrive gears that save fuel whendriving at a constant engine speed. The steeringwheel paddles* can be used to shift up or downmanually. The instrument panel shows the gearcurrently in use.

CAUTION
Check the operating temperature of thetransmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.

Symbols in the instrument panel
If a problem should occur with the transmission, asymbol and a message will appear in the instru-ment panel.

Gear selector positions forautomatic transmissions
In vehicles with an automatic transmission, thesystem selects the optimal gear for the currentdriving conditions. The transmission also has amanual mode.
The instrument panel shows which gear is cur-rently in use:
P, R, N, D or B.
For manual shifting, the gear indicator in theinstrument panel displays the gear currentlybeing used (1-8).

Selecting gears
The gear selector is a shift-by-wire selector,where shifting is done electronically instead ofmechanically. This makes shifting easier and thegear positions more distinct.
