Stopping hybrid battery charging To stop charging of the hybrid battery, unlock the vehicle, unplug the charging cable fromthe vehicle's charging socket and thenunplug the cable from the 120/240 V outlet(alternating current).
CAUTION
Before the charging cable is removed from the vehicle's charging socket, the vehiclemust be unlocked using the unlock buttonon the remote key. This must be done evenif the vehicle's doors are already unlocked.If the vehicle is not unlocked using theunlock button, the charging cable or sys-tem may be damaged.
NOTE
Always unlock the vehicle so that charging is cut off before the connection to the120/240 V outlet (AC, alternating current)is disconnected. Note that the chargingcable must be disconnected from the vehi-cle's charging socket before it is discon-nected from the 120/240 V outlet, partlyto prevent damage to the system and partyto prevent unintentional interruption ofcharging.
Unlock the vehicle with the remote key. Charging will stop.
Press the lock button on the charging cable's handle. The handle will bereleased/unlocked. Unplug the cable fromthe vehicle's charging socket and closethe charger door.

Long-term storage of vehicles with hybrid batteries To help minimize degradation of the hybrid battery if the vehicle is not driven for a pro-longed period (longer than 1 month) thehybrid battery charge level should be kept atapprox. 25% according to the gauge in theinstrument panel.
Do as follows:
1. If the hybrid battery charge level is high,drive the vehicle until the charge level is approximately 25%. If the charge level islow, charge the battery until the level rea-ches approximately 25%. 2. If the vehicle is not driven for more than 6
months or the hybrid battery's chargelevel is noticeably below the 25% mark,charge the battery to about 25% to helpcompensate for the natural battery dis-charge that occurs in long-term storage.Regularly check the charge level using thegauge in the instrument display.
NOTE
Store the vehicle in as cool a location as possible to minimize battery aging duringlong-term storage. In the summer, park thevehicle indoors or in a shady location,whichever is cooler.

Starting the vehicle
The vehicle can be started using the start knob in the tunnel console when the remotekey is in the passenger compartment.
Start knob in the tunnel console.
WARNING
Before starting:
Buckle your seat belt.
Adjust the seat, steering wheel and mirrors.
Make sure you can fully depress thebrake pedal.
The remote key is not physically used to startthe ignition because the vehicle is equippedwith the keyless Passive Start system. To start the vehicle:
CAUTION
The vehicle cannot be started if the charg- ing cable is still plugged in. Make sure topull out the charging cable from the charg-ing socket before starting the vehicle.
1. The remote key must be inside the vehicle.
For vehicles with Passive Start, the key must be in the front section of the passen-ger compartment. With the optional key- less locking/unlocking function *, the key
can be anywhere in the vehicle.
2. Press and hold down the brake pedal 1
as
far as possible.
3. Turn the start knob clockwise and release. The control will automatically return to the original position.
WARNING
Never use more than one inlay mat at a time on the driver's floor. If any othertype of floor mat is used, remove theoriginal mat from the driver's seat floorbefore driving. All types of mats mustbe securely anchored in the attach-ment points in the floor. Make sure thefloor mat does not impede the move-ment of the brake pedal or acceleratorpedal in any way, as this could be aserious safety hazard.
Volvo's floor mats are specially manu-factured for your vehicle. They must beproperly secured in the attachmentpoints in the floor to help ensure theycannot slide and become trappedunder the pedals.
The starter motor will crank until the enginestarts or until overheating protection is trig-gered. During normal start conditions, the vehicle's electric motor will be prioritized and the gaso-line engine will remain off. This means thatonce the start knob is turned clockwise, theelectric motor has been "started" and the vehi-cle is ready to be driven. The warning andinformation symbols in the instrument panel
1 If the vehicle is moving, it is only necessary to turn the start knob clockwise to start the engine.

Drive systemsVolvo Twin Engine combines a combustion engine for the front wheels and an electricmotor for the rear wheels.
Two drive systemsDepending on the selected drive mode and power available in the electric motor, the drivesystems can either be used separately or intandem. The electric motor gets its energy from a hybrid battery located under the tunnel con-sole. The hybrid can be charged from a walloutlet or in a special charging station. Thecombustion engine can also charge the hybridbattery using a special high-voltage generator. Both the combustion engine and the electric motor can generate power directly to thewheels. An advanced control system coordi-nates both the drive systems to help optimizedriving economy.
Hybrid battery - The hybrid battery's func- tion is to store electrical current. Thisenergy is provided by plugging the charg-ing cable into an electrical outlet, throughregenerative braking or from the high-volt-age generator. This provides current topower the electric motor and to temporar-ily power the electrical air conditioning toprecondition the passenger compartment.
Combustion engine - The combustion engine starts when the charge level in thehybrid battery is too low to provide thepower output requested by the driver.
High-voltage generator 6
- Charges the
hybrid battery. Starter for the combustion engine. Can provide the combustion engine with extra electrical current.
Electric motor - Powers the vehicle using electricity. Can provide extra torque andpower during acceleration. Provides elec-trical all-wheel drive functionality. Regen-erates braking energy into electrical cur-rent.

WARNING
Do not leave the vehicle in an unventilated area with a drive mode activated and thecombustion engine switched off. Theengine will start automatically if the chargelevel in the hybrid battery is low and theresulting exhaust gases can be very harm-ful to people and animals.
Hybrid
This is the default mode in which the elec- tric motor and combustion engine worktogether.
The vehicle starts in
Hybrid mode. The control
system uses both the electric motor and the gasoline engine – separately or in tandem –and adapts utilization with regard to perform-ance, fuel consumption and comfort. Drivingcapacity on the electric motor alone is deter-mined by factors such as the hybrid battery'scharge level, the need for heat or cooling inthe passenger compartment, etc. If there is sufficient charge in the battery, it is possible to drive solely on electric power.When the accelerator pedal is pressed, onlythe electric motor will be activated until thebattery reaches a certain charge level. Abovethis level, the current in the battery cannotsupply the power requested by the acceleratorpedal and the combustion engine will start. When the hybrid battery's charge level is low, the combustion engine will start more fre- quently to save the remaining current in thebattery. Charge the hybrid battery from a120-240 volt outlet using a charging cable, or activate
Charge in Function view to reset the
option of only using the electric motor. This drive mode is designed for low energy consumption with a mix between the electricmotor and gasoline engine, without compro-mising on climate comfort or driving experi-ence. When faster acceleration is requestedby the driver, the electric driveline will be uti-lized to help provide maximum additionalpower. The vehicle also monitors the driving condi- tions and automatically engages all-wheeldrive if necessary. All-wheel drive and extraelectric power are always available regardlessof the battery's charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will be displayed in the instrument panel. Thegauge will indicate the amount of electricalcurrent required when the driver depressesthe accelerator pedal. The marker between thelightning and the drop shows how much cur-rent is available.
The instrument panel gauge when both the electric motor and the combustion engine are being used.
The instrument panel also shows how much current is being restoredto the battery (regenerated) duringlight braking.

Energy distribution in hybrid mode using map data *
The
Hybrid drive mode is the vehicle's
default drive mode in which the electric motor and the combustion engine work sepa-rately or together in hybrid mode. If a destina-tion has been selected in the navigation sys- tem *, the Predictive Efficiency 8
function can
use map data to effectively distribute the electric power consumption throughout thetrip.
This can lower fuel consumption in compari- son with normal hybrid mode, in which thevehicle first runs on electricity and thenswitches to the gasoline engine when thehybrid battery is discharged.
FunctionIf the distance to the selected destination isgreater than the calculated range on the elec-tric motor, the function will distribute the elec-tric power to make consumption as energy-efficient as possible throughout the trip. Thismakes it possible to avoid situations in whichnormal hybrid mode would otherwise use alarge portion of the electric power to e.g. usethe electric motor at high speeds on a high-way and then use the combustion engine atlower speeds during city driving. The greatest fuel savings are achieved when
the trip begins on a highway
the trip is between 50 and 100 km (30and 60 miles) long
the hybrid battery is fully charged at thestart of the trip.
Requirements for the functionCertain conditions must be met for the func-tion to be possible:
A destination must be set in the navigationsystem and the distance to the destinationmust be longer than the possible rangeusing only the electric motor.

Hybrid drive mode must be selected.
The
Hold and Charge functions must be
disabled.
The hybrid battery must be charged.
Usage tipsIf you commute and it is not possible to charge the vehicle at work, enter your work-place as a waypoint and your home as thedestination. Discharging of the hybrid batterywill then be distributed over the entire com-mute to and from work. Add similar commutes, i.e. the route between two charges, as
Favorites in the navigation
system to facilitate access.
