Stopping hybrid battery charging
To stop charging of the hybrid battery, unlock the vehicle, unplug the charging cable from thevehicle's charging socket and then unplug thecable from the 120/240 V outlet (alternatingcurrent).
NOTE
Always unlock the vehicle so that charging is cut off before the connection to the120/240 V outlet (AC, alternating current) isdisconnected. Note that the charging cablemust be disconnected from the vehicle'scharging socket before it is disconnectedfrom the 120/240 V outlet, partly to preventdamage to the system and party to preventunintentional interruption of charging.
Unlock the vehicle with the remote key. Charging will stop.
Press the lock button on the charging cable's handle. The handle will be released/unlocked. Unplug the cable from the vehi-cle's charging socket and close the chargerdoor.
Unplug the cable from the 120/240 V outlet. Stow the charging cable in the storage com- partment under the cargo area floor.
Charging cable automatically locksIf the charging cable cannot be removed from thecharging socket, it will automatically lock intoplace again after unlocking to maximize charging and range and to enable preconditioning beforedriving. The charging cable can be removed againif the vehicle is unlocked using the remote key. For vehicles with Passive Entry
*, the handle can
be used to lock and unlock.

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 6
months 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.

All Wheel Drive (AWD)All-wheel drive, All Wheel Drive (AWD), also called four-wheel drive, means that power is dis-tributed to all four wheels, which improves trac-tion.
The electric motor that powers the rear wheels enables electronic all-wheel drive functionality. To achieve the best traction, power is automati- cally directed to the wheels that have the bestgrip. The system continuously calculates theneed for torque to the rear wheels, and canimmediately redistribute up to half of the engine'storque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions, mostof the engine's power is directed to the frontwheels. When the vehicle is stationary, all-wheeldrive is always activated in preparation for maxi-mum traction during acceleration. All-wheel drive reacts differently depending on which drive mode is selected.

Drive systems
Volvo Twin Engine combines a combustion engine for the front wheels and an electric motorfor 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 in tan-dem. The electric motor gets its energy from a hybrid battery located under the tunnel console. Thehybrid can be charged from a wall outlet or in a special charging station. The combustion engine can also charge the hybrid battery using a special high-voltage generator. Both the combustion engine and the electric motor can generate power directly to the wheels.An advanced control system coordinates both thedrive systems to help optimize driving economy.
Hybrid battery - The hybrid battery's function is to store electrical current. This energy isprovided by plugging the charging cable intoan electrical outlet, through regenerativebraking or from the high-voltage generator.This provides current to power the electricmotor and to temporarily power the electricalair conditioning to precondition the passen-ger compartment.
Combustion engine - The combustion engine starts when the charge level in the hybridbattery is too low to provide the power outputrequested by the driver.

battery. Starter for the combustion 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's many 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
• Pneumatic suspension
* and shock absorbers
• Instrument panel
• Climate control settings
Select the drive mode that is best suited to the current 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 emit any 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 unventilated area 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.
HYBRID
• This is the default mode in which the electric motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control system uses both the electric motor and the gas-oline engine - separately or in tandem - and cal-culates optimal utilization with regard to perform-ance, fuel consumption and comfort. At highspeeds, ground clearance is automatically low- ered 4
to reduce air resistance. Driving capacity on
the electric motor alone is determined by factors such as the hybrid battery's charge level, the need for heat/cooling in the passenger compart-ment, etc. If there is sufficient charge in the battery, it is possible to drive solely on electric power. Whenthe accelerator pedal is pressed, only the electricmotor will be activated until the battery reaches acertain charge level. Above this level, the currentin the battery cannot supply the power requestedby the accelerator pedal and the combustionengine will start. When the hybrid battery's charge level is low, the combustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 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 con- sumption with an optimized mix between theelectric motor and gasoline engine, without com-promising on climate comfort or driving experi-ence. When faster acceleration is requested bythe driver, the electric driveline will be utilized tohelp provide maximum additional power. Thevehicle also monitors the driving conditions andautomatically engages all-wheel drive if neces-sary. All-wheel drive and extra electric power arealways available regardless of the battery'scharging status.

Economical driving
Drive economically and environmentally con- scious by thinking ahead, avoiding rapid startsand stops and adapting driving style and speedto the current traffic conditions.
Planning for electric drivingIt is important to plan electric motor use carefully to achieve the best possible mileage:
Charge
• Charge the vehicle regularly by plugging it into an electrical outlet. Make it a habit to always begin trips with the hybrid battery fully charged.
• Locate charging stations along your route.
• If possible, choose parking spots with charg-ing stations.
NOTE
Charge the vehicle from the electricity grid as often as possible!
Preconditioning
•
Whenever possible, precondition the vehicle before driving by connecting the chargingcable to an electrical outlet.
• Avoid parking the vehicle somewhere wherethe interior will become too hot or too coldwhile the vehicle is parked. If possible, parkthe vehicle in a climate-controlled garage. •
During a short drive after passenger com-partment preconditioning, turn off the pas-senger compartment fan or the air condition-ing in a hot climate.
• If preconditioning is not possible when it iscold outside, use seat and steering wheelheating first. Avoid heating the entire pas-senger compartment to reduce the amountof current being taken from the hybrid bat-tery.

Factors the driver can control
The driver should be aware that the following fac- tors help conserve energy and improve drivingrange:• charging the battery regularly
• preconditioning
• Pure drive mode
• climate control settings
• speed and acceleration
• the
Hold function
• tires and tire pressure.
The following table shows the approximate rela- tionship between constant speed and drivingrange. Driving at a lower constant speed helpsincrease the electric motor's driving range.
Constant speed
100 km/h (62 mph) 50 %80 km/h (50 mph) 70 %
60 km/h (37 mph) 90 %
50 km/h (31 mph) 100 %
NOTE
• The figures shown in the tables pertain to a new vehicle.
• None of the figures are absolute and areaffected by e.g. driving style, environmentand other conditions.

"Hold" and "Charge" functions
In certain situations, it can be useful to control the hybrid battery's charge level while driving. This is possible with the
Hold and Charge func-
tions, which are available in all drive modes.
Function buttons for Hold and ChargeThe functions can be activated in the center dis- play's Function view.
Hold
Battery level sustained for later use.
This function retains the charge in the hybrid battery for theelectric motor and saves availa-ble electrical current for use at
a later time, such as when driving in an urban area or residential neighborhood.
Hold is availa-
ble regardless of the hybrid battery's charge level. The vehicle will function as in normal hybrid driv- ing with a discharged battery - in addition toreusing energy from e.g. regenerative braking, thecombustion engine will be used more frequentlyto maintain the charge in the battery.
