Charging the hybrid battery In addition to the conventional fuel tank, Twin Engine Plug-in Hybrid vehicles are also equip-ped with a rechargeable lithium-ion hybrid bat-tery.
The hybrid battery is recharged using a charging cable located in a storage compartment underthe floor of the cargo area. See also the article"Charging cable."
WARNING
The hybrid electrical system in your vehicle uses high voltage electrical current. Any dam-age to this system or to the hybrid batterymay result in the danger of overheating, fire,or serious injury. If the vehicle is involved in acollision or is subjected to flooding, fires, etc.,have it inspected by a trained and qualifiedVolvo service technician. Prior to this inspec-tion, the vehicle should be parked outdoors ata safe distance from any building or poten-tially flammable materials.
The hybrid battery's charging time depends on the charging current used.
NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
Charging is indicated in three ways: • Charge module (the unit that is plugged into the wall socket): The blue indicator light onthe cable's charge module will flash red sev-eral times when the unit is plugged into awall socket while a safety check is being per-formed and will then glow steadily blue toindicate that the charger is ready to use.
• A green indicator light in the vehicle's charg-ing socket will flash green while the batteryis charging and will glow steadily green whenthe hybrid battery is fully charged. The blueindicator light in the charge module will alsoflash while charging is underway and willglow steadily blue when charging is comple-ted.
• A gauge in the instrument panel will alsoindicate the battery's charge level.
The hybrid battery charging process also chargesthe vehicle's start battery. If the hybrid battery's temperature is below – 13 ºF (–10 ºC) or above +104 ºF (+40 ºC), some
of the vehicle's functions may be reduced or not

404be available at all (e.g., drive mode may not be available). The electric motor cannot be used if the hybrid battery's temperature is too low or too high. If thePURE drive mode is selected, the gasolineengine will be used.
Temperature controlDuring charging, if the temperature in the charg-ing cable becomes too high and reaches a criticallimit, charging will be interrupted.
CAUTION
If charging is interrupted repeatedly, have the charging cable and the vehicle's chargingsystem inspected by a trained and qualifiedVolvo service technician.
Charging using the gasoline engine
Current is generated to charge the hybrid battery, such as light braking and when engine braking on down-slopes
Using the
B gear mode when driving on down-
slopes will also recharge the hybrid battery. The hybrid battery can also be charged by the gasoline engine. During light braking, the batteryis recharged.

Maintaining/increasing the hybrid battery's charge while driving In certain situations, it can be useful to control the hybrid battery's charge level while the vehicleis being driven. The hybrid battery functions
Hold and Charge while driving are available in
all drive modes.
The "Hold" and "Charge" function
buttons
These functions are activated from the center display's Function view.
Hold
Battery level sustained for later use.
This function saves the hybrid battery's charge for use at alater time such as when drivingin an urban area or residential
neighborhood.
Hold is available regardless of the
hybrid battery's charge level. The vehicle will function as in normal hybrid driv- ing and will use energy from e.g., regenerativebraking to support the gasoline engine.
Charge
Engine charges hybrid battery.
This function charges the hybrid battery with the help of the gasoline engine for use at a latertime. It is not available if the hybrid battery'scharge level is already high. After the battery has been charged up to a cer- tain level,
Hold is activated automatically.
Symbol in the instrument panel
The symbol will appear in the instrument
panel when either of these functions is activated. See also the article "Hybrid-related symbols andmessages" for additional information.

Drive modes
Selecting a drive mode affects the vehicle's driv- ing characteristics to help make driving moreenjoyable or easier in certain types of situations.
The following systems are adapted to help pro- vide the best vehicle performance in the respec-tive drive modes: • Steering
• Engine/transmission/All Wheel Drive
*
• Brakes
• Pneumatic suspensionSuspension control
• Instrument panel
• Climate system settings
Select the drive mode best suited to the current driving conditions. Please be aware that not all modes can be selected in all driving situations. The selectedmode will be displayed in the instrument panel.
Selecting a drive mode
1. Press the DRIVE MODE control in the tun-
nel console.
> A pop-up menu will open in the center display.
2. Roll the control upward or downward to scroll to the desired drive mode.
3. Press the control again to select it. A drive mode can also be selected by tapping its button on the center display.
> The selected drive mode will be displayedin the instrument panel.
When a drive mode cannot be selected, one of the following messages may be displayed:
•

•Not possible to select due to low battery
•Not possible to select due to low temperature
•Not possible to select due to limitations
•Not possible to select due to high speed.
Available drive modes
WARNING
• Keep in mind that a hybrid vehicle using the electric motor does not emit enginenoise and may be difficult to detect fore.g., children, pedestrians, cyclists or ani-mals. This is particularly true at lowspeeds.
• Do not leave the vehicle in an unventila-ted area with a drive mode activated andthe gasoline engine switched off. Theengine will start automatically if thecharge level in the hybrid battery is lowand the resulting exhaust gases can bevery harmful to people or animals.

HYBRID
This is the default mode in which the electric motor and gasoline engine are both utilized. The vehicle starts in
Hybrid mode. The control
system uses the electric motor and the gasoline engine, separately or in tandem, and calculatesoptimal use with respect to performance, fuelconsumption and comfort. At higher speeds,ground clearance is lowered automatically to helpreduce wind resistance. Driving capacity on theelectric motor alone is determined by the hybridbattery's charge level and e.g., the need for heat-ing/cooling in the passenger compartment. If sufficient electrical energy is available, only the electric motor will be activated when the driverpresses the accelerator pedal up to a certainlevel. Above this level, the gasoline engine willstart. Charge the hybrid battery using the charg- ing cable or activate the vehicle's
Charge func-
tion in the center display's Top view in order to drive using the electric motor only. See also thearticle "Maintaining/increasing hybrid batterycharge while driving" for additional information. Information in the instrument panel When driving in
Hybrid mode, a hybrid gauge will
be displayed in the instrument panel. The indica- tor in the gauge will show the amount of electri-cal current required when the driver depressesthe accelerator pedal. The marker between the"lightning" and "oil drop" symbols indicates theamount of energy available. See also the article "Hybrid-related information in the instrumentpanel" for additional information.
The instrument panel gauge when both the electric motor and gasoline engine are being used
The gauge also indicates when the battery is being recharged (regener-ated) during light braking. See the arti-cle "Brakes" for additional information.
PURE
Driver display when only the electric motor is being used
This mode activates the electric motor only with as low energy consumption as possible and thelowest possible carbon dioxide emissions.
Pure maximizes the use of the hybrid battery.
Ground clearance will be lowered to help reduce wind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery is
sufficiently charged. If the charge level gets too low, the gasoline engine will start. The gasoline engine will also start:

•
If the vehicle's speed goes above approx. 78 mph (125 km/h)
• If the driver wants more response than theelectric motor alone can provide
• If factors such as cold weather, etc., affectthe system or components
ECO climate
In the Pure drive mode, ECO climate in the pas-
senger compartment is activated automatically to help reduce energy consumption.
NOTE
When the Pure drive mode is activated, set-
tings for certain climate system/electricity- consuming functions are reduced. Some ofthese settings can be reset manually but fullfunctionality will only be restored by leaving the
Pure drive mode or by adapting the set-
tings in the Individual drive mode to full cli-
mate system functionality.
If condensation forms on the windows, tap the max. defroster button, which will function nor-mally.
OFF ROAD
This mode helps maximize the vehicle's capacity to traverse difficult terrain or poor roads. In OFF ROAD, ground clearance is maximized, the steering is light, All Wheel Drive and HillDescent Control are activated and a compass will be displayed between the speedometer and tach-ometer in the instrument panel. This drive mode can only be activated at low speeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and AWD willbe activated.
CAUTION
OFF ROAD drive mode may not be used if the vehicle is towing a trailer without an elec-trical connection. This could result in damageto the pneumatic suspension system's bel-lows.
NOTE
•
This mode is not intended for normal street driving.
• Due to the increased ground clearance, ifthe OFF ROAD mode was selected whenthe engine was switched off, the suspen-sion will lower when the engine is restar-ted.
AWD
This mode offers improved traction on slippery surfaces by using four-wheel drive. It also helpsincrease directional stability at higher speeds, forexample when towing a trailer. In this mode, both the electric motor and the gas-oline engine are utilized, which results in higherfuel consumption. In the other drive modes, the vehicle automati- cally adapts the need for all-wheel drive accord-ing to the road surface and may activate the elec-tric motor or start the gasoline engine asrequired.
POWER
Power mode is intended for sportier, more active
driving. This mode maximizes the combined effects of the electric motor and the gasoline engine andprovides power to all four wheels. Response topressure on the accelerator pedal is more imme-diate and the transmission shifts up at higherrpm. Steering response is also more immediate,the suspension is stiffer and lower ground clear-ance reduces body roll when cornering. In this mode, both the electric motor and the gas- oline engine are utilized, which results in higherfuel consumption.

Use of the gasoline engineAn advanced control system determines the dis- tance that the vehicle can be driven using the gasoline engine, electric motor or both at thesame time. Its primary function is to use the motor/engine and 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 gasoline engine.
