4. The charging cable's coupler will lock onto
the charging socket and charging will begin within approx. 10 seconds. The approximateremaining charging time and charging statuswill be displayed in the instrument panel. Seealso the article "Hybrid battery charge sta-tus." Charging will be temporarily interrupted if the vehicle is unlocked: •If a door is opened, charging will restart within 2 minutes.
• if no door is opened, the vehicle will auto-matically relock and charging will restartafter 1 minute.
NOTE
Charging status is shown in the instrument panel, which goes dark after a period of time.Reactivate the instrument panel by: •pressing the brake pedal
• opening one of the doors
• putting the ignition in mode
I ( without
pressing the brake pedal , turn the start
knob to START and release it).
CAUTION
Never disconnect the charging cable from the 120-/240-volt socket while charging is inprogress. This could damage the socket. Always stop the charging process (by unlock- ing the vehicle) and disconnect the chargingcable from the vehicle's charging socket before disconnecting the other end from the
120-/240-volt socket being used.
During the charging process, condensation may form under the vehicle, which is normal and iscaused by cooling the hybrid battery.

Charging the hybrid battery In addition to the conventional fuel tank, the XC90 T8 Twin Engine Plug-in Hybrid is alsoequipped with a rechargeable lithium-ion hybridbattery.
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 charges the 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 be 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.

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
• Suspension 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. A drive mode can also be selected by tap- ping its button on the center display.
3. Press the control again to select it. When a driving mode cannot be selected, one of the following messages may be displayed:

Available drive modes
HYBRID
This is the default mode. The vehicle normally starts in
Hybrid mode 4
. The
engine management system uses both the elec- tric motor and gasoline engine (separately or intandem) and calculates the optimal levels of per-formance, fuel consumption and comfort. Athigher speeds, ground clearance is reducedautomatically to help reduce wind resistance. The amount of driving done using only the elec- tric motor in
Hybrid mode is determined by the
hybrid battery's charge level and the need for heating/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.The instrument panel gauge when both the electric motor and gasoline engine are being used
The long needle in the gauge indicates the amount of energy that the vehicle is currentlyusing. The short white line between the "light-ning" and "oil drop" symbols indicates theamount of energy available. See also the article"General information about the XC90 T8 TwinEngine Plug-in Hybrid" for additional information. The gasoline engine starts when the response required when the driver presses the acceleratorpedal cannot be provided by the electric motoralone. The gauge also indicates when the battery is being recharged (regenerated) during light brak-ing. See the article "Brakes" for additional infor-mation. When the hybrid battery's charge level is low, thegasoline engine will start more often to help con-serve electrical energy. Charge the battery withthe charging cable as soon as possible or switch to the
Save drive mode.
PURE
This mode activates the electric motor only with as low energy consumption as possible and thelowest possible carbon dioxide emissions. 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 level gets too low, the gasoline engine will start. The gasoline engine will also start: • If the vehicle's speed goes above approx. 75 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
To restart the climate system functions that have been reduced in the mode, press the,
AUTO or
defroster buttons.
4 Unless the vehicle was switched off in Off Road mode. If so, it will restart in Off Road mode.

SAVE
This mode makes it possible to save electrical energy (hybrid battery charge) for times whenusing the electric motor is more suitable (e.g., citydriving). Using the electric motor only saves more fuel at low speeds than at high ones. Therefore, use theSAVE mode primarily when the hybrid battery'scharge level is high and driving will initially be athighway speeds but will end with city drivingwhen electric driving is preferable. If the hybrid battery's charge level is low when this mode is selected, the gasoline engine willstart and charge the hybrid battery up to approx.33%. If the battery's charge level is already above33%, this level will be maintained by the enginemanagement system, which will start/stop the gasoline engine in the same way as in
Hybriddrive mode. This mode increases fuel consumption because the gasoline engine is used to conserve batterycharge for later use.
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 compassand altimeter will be displayed in the instrumentpanel.This drive mode can only be activated at lowspeeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and AWD willbe activated. This mode is not intended for normal street driv- ing.
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.
Due to the increased ground clearance, if the OFF ROAD mode was selected when the enginewas switched off, it will also restart in this mode.
AWD
This mode offers improved traction using four- wheel drive and is intended primarily for low-speed driving on slippery surfaces. However, italso helps increase directional stability at higherspeeds. In this mode, both the electric motor and the gas- oline engine are used continuously, which resultsin higher fuel consumption.
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 higherspeeds. Steering response is also more immedi-ate, the suspension is stiffer and lower groundclearance reduces body roll when cornering. In this mode, both the electric motor and the gas- oline engine are used continuously, which resultsin higher fuel consumption.
