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.

Drive modes
Drive modes affect the vehicle's driving charac-teristics in different ways to enhance and sim-plify the driving experience in certain types of sit-uations.
Drive modes enable easy access to the vehicle'smany functions and settings in different drivingsituations. The following systems are adapted tohelp optimize driving characteristics in each drivemode:
Steering
Engine/transmission/all-wheel drive
Brakes
Shock absorbers
Instrument panel
Climate control settings
Select the drive mode that is best suited to thecurrent driving conditions. Keep in mind that notall drive modes are available in all situations.
Available drive modes
WARNING
Keep in mind that the vehicle does not emitany engine noise when using the electricmotor and may therefore be difficult to detectfor children, pedestrians, cyclists or animals.This is particularly true at low speeds, e.g. inparking lots.

WARNING
Do not leave the vehicle in an unventilatedarea with a drive mode activated and the com-bustion engine switched off. The engine willstart automatically if the charge level in thehybrid battery is low and the resulting exhaustgases can be very harmful to people and ani-mals.

Using the electric or combustion
engine
An advanced control system determines the dis-tance that the vehicle can be driven on the com-bustion engine, electric motor, or both at thesame time.
Its primary function is to use the motor/engineand the current available in the hybrid battery asefficiently as possible based on the characteris-tics of the various drive modes and the poweroutput requested by the driver by pressing theaccelerator pedal.
In certain cases, temporary limitations in the sys-tem or mandatory functions to help maintain alow overall emissions level may result in greateruse of the combustion engine.
