Ignition modes
The vehicle's ignition can be put in various modes (levels) to make different functions availa-ble.
The vehicle's ignition has 3 modes: 0, I, and II
that can be used to operate various functions without starting the engine. The following tableshows examples of which functions are availablein the respective modes.
Mode Functions available
0 •The odometer, clock and tem- perature gauge are illuminated
• Power seats
* can be adjusted
• The power windows can be oper-ated
• The 12-volt socket in the cargocompartment can be used
• The center display is activatedand can be used
• The infotainment system can beused for a limited time
In this mode, certain functions canonly be used for a limited time to helpminimize battery drain

Battery drain Your vehicle's electrical functions drain the bat- tery to varying extents.
Avoid using ignition mode
II as much as posssi-
ble, or electrical functions that require a great deal of electrical current when the engine is notrunning. Using ignition mode I whenever possible con-
sumes less electrical current. Functions that require a great deal of electrical current include:
• the climate system blower
• headlights
• wipers
• infotainment system (especially at high vol-ume).
If the battery's charge level is low, a text messagewill appear in the instrument panel. The vehicle'senergy-saving function will then turn off orreduce certain functions that are currently con-suming electrical current. If the battery needs to be recharged, start the engine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

WARNING
Before starting the engine:
• Fasten the seat belt.
• Check that the seat, steering wheel and mirrors are adjusted properly.
• Make sure the brake pedal can bedepressed completely. Adjust the seat ifnecessary.

To start the engine.
1. A remote key must be in the passenger com-
partment. On models with the standard Passive Start, the key has to be in the frontsection of the passenger compartment. If thevehicle is equipped the optional PassiveEntry system (keyless locking/unlocking) thekey can be anywhere in the vehicle.
2. Press firmly on the brake pedal 2
.
3. Turn the start knob toward START and
release it to start the engine.
> The starter motor will crank until the engine starts or its overheating protection is triggered.
WARNING
• Never use more than one floor mat at a time on the driver's floor. Before driving,remove the original mat from the driver'sseat floor before using any other type offloor mat. Any mat used in this positionshould be securely and properly anchoredin the attaching pins. An extra mat on thedriver's floor can cause the acceleratorand/or brake pedal to catch. Check thatthe movement of these pedals is notimpeded.
• Volvo's floor mats are specially manufac-tured for your car. They must be firmlysecured in the clips on the floor so thatthey cannot slide and become trappedunder the pedals on the driver's side.
During normal starts, the electric motor is priori-tized and the gasoline engine will not start. Thismeans that when the start knob has been turned toward START and released, the electric motor is
activated ("started") and the vehicle is ready to be driven. The warning and information symbolsin the instrument panel will go out and thechosen theme will be displayed to indicate thatthe electric motor has been activated. However, in certain situations, such as in coldweather or if the hybrid battery is not sufficientlycharged, the gasoline engine will start instead. The vehicle should not be started if the charging cable is connected.
However, if the
cable cannot be disconnected or if the vehicleincorrectly detects a cable that is not connected,the vehicle can be started using an override pro-cedure:
1. Press the brake pedal and turn the start
knob to START.
2.
Remove charge cable to start will appear
in the instrument panel.
3. Turn the start knob to START again.
4.
Charge cable removed? Press start button 7s to start will be displayed. Turn
the start knob to START again and hold it for
7 seconds to start the vehicle.
NOTE
The vehicle cannot be started if the hybrid battery is discharged.
2 If the vehicle is moving, it is only necessary to turn the start knob toward START to start the engine.

Back-up reader in the tunnel console
If Vehicle key not found is displayed in the
instrument panel, place the remote key in the back-up reader in the tunnel console (see theillustration) and try again to start the engine.
NOTE
When the remote key is in the back-up reader, be sure there are no other metallicobjects (e.g., other keys, coins, cell phones) inthe cup holder. This could affect the back-upreader's function.
If Vehicle start System check, wait is dis-
played in the instrument panel when you try to start the vehicle, wait until the message is nolonger displayed and try to start again.
CAUTION
If the engine does not start after the third try, wait for approximately 3 minutes before tryingto start it again to give the battery time torecover its starting capacity.
WARNING
• Always remove the remote key from the passenger compartment when leaving thevehicle and ensure that the ignition in mode
0.
• On vehicles with the optional Passive Entry, never remove the remote key fromthe vehicle while it is being driven ortowed.
• Always place the gear selector in Parkand apply the parking brake before leav-ing the vehicle. Never leave the vehicleunattended with the engine running.
• Always open garage doors fully beforestarting the engine inside a garage toensure adequate ventilation. The exhaustgases contain carbon monoxide, which isinvisible and odorless but very poisonous.
NOTE
After a cold start, idle speed may be noticea- bly higher than normal for a short period. Thisis done to help bring components in theemission control system to their normal oper-ating temperature as quickly as possible,which enables them to control emissions andhelp reduce the vehicle's impact on the envi-ronment.
CAUTION
•
When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
• Selecting
P or N when idling at a stand-
still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.

Driving systems
Twin Engine Plug-in Hybrid vehicles are parallel hybrids, which means that they have two sepa-rate drive systems: an electric motor and a gaso-line engine.
Two drive systemsDepending on the drive mode selected and the amount of electric power available in the hybridbattery, the two systems can be used in tandemor separately. The electric motor is powered by a hybrid battery located under the tunnel console. This batterycan be charged from a wall socket or specialcharging stations. The gasoline engine can alsocharge the hybrid battery using a special high-voltage generator. The gasoline engine and electric motor both gen- erate power directly to the wheels. A control sys-tem coordinates both of the drive systems to helpoptimize driving economy.

Hybrid battery: stores electrical current, which is provided by connecting the chargingcable to the electricity grid, through regener-ative braking or from the high-voltage gener-ator. This makes it possible to drive using theelectric motor or to power the electrical airconditioning to precondition the passengercompartment.
Gasoline engine: starts when the charge level in the electric motor is too low to pro-vide the power output that the driver requires.
High voltage generator3
: charges the hybrid
battery and starts the gasoline engine. It can also provide the gasoline engine with extraelectrical current.
Electric motor: powers the vehicle using electricity and can provide extra torque andpower during acceleration. It combines with the gasoline engine to provide all-wheel drivefunctionality and regenerates braking energyinto electrical current.
