Driving through standing water
The vehicle should be driven with extreme cau-tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to adepth approximately level with the floor at walk-ing speed to help prevent water from enteringthe differential and/or the transmission or dam-aging electrical components.
•If possible, check the depth of the waterbefore driving through it. Take particular carewhen driving through flowing water.
•Before driving through water, always selectthe Off Road drive mode to ensure that thegasoline engine is running and to maximizeground clearance.
•After driving through water, apply the brakesand check that they are functioning correctly.
•Clean the electrical connections for trailerwiring after driving in mud or water.
•When driving through water, maintain lowspeed and do not stop in the water.

CAUTION
•Damage may occur to the engine, trans-mission, electrical components, etc. if thevehicle is driven through water higherthan its floor level. Be aware that wavescreated by other vehicles could cause thelevel to temporarily be above the vehicle'sfloor level.
•Damage to any components due to waterabove the floor level, vapor lock or insuffi-cient oil is not covered under warranty.
•If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water and inspected by a trained andqualified Volvo service technician.

WARNING
•Avoid driving through standing or rushingwater. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.
•If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.

Overheating the engine andtransmission
In demanding driving conditions, such as whentransporting heavy loads, driving in mountainousareas or in very hot weather there is a risk ofoverheating the engine or transmission.
•The engine's output may be slightly limited ifthere is a risk of overheating.
•Remove e.g., auxiliary lights mounted in frontof the grille in hot weather.
•If the temperature of the engine coolantbecomes too high, the warning symbol willilluminate and the message Enginetemperature/Stop safely will be displayed.Stop the vehicle as soon as possible in asafe place and let the engine idle for severalminutes.
•If the message Engine temperature/Hightemperature Turn off engine or Enginecoolant/Stop safely is displayed, stopsafely and turn off the engine.
•If the transmission begins to overheat, analternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol willilluminate and the message TransmissionwarmHigh temperature Reduce speedor Transmission warmStop safely, waitfor cooling will be displayed in the instru-ment panel.

Selecting a drive mode
1.Press the DRIVE MODE control in the tun-nel console.
>A pop-up menu will open in the centerdisplay.
2. Roll the control upward or downward to scrollto 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 ofthe following messages may be displayed:
•Not possible to select due to gear inmanual
•Not possible to select due to low battery
•Not possible to select due to lowtemperature
•Not possible to select due to limitations
•Not possible to select due to highspeed.

Available drive modes
HYBRID
This is the default mode.
The vehicle normally starts in Hybrid mode 4. Theengine 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 thehybrid battery's charge level and the need forheating/cooling in the passenger compartment.
If sufficient electrical energy is available, only theelectric 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 electricmotor and gasoline engine are being used
The long needle in the gauge indicates theamount 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 responserequired when the driver presses the acceleratorpedal cannot be provided by the electric motoralone.
The gauge also indicates when the battery isbeing recharged (regenerated) during light brak-ing. See the article "Brakes" for additional infor-mation.
4Unless the vehicle was switched off in Off Road mode. If so, it will restart in Off Road mode.

STARTING AND DRIVING
422
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.

PURE
This mode activates the electric motor only withas low energy consumption as possible and thelowest possible carbon dioxide emissions.
Ground clearance will be lowered to help reducewind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery issufficiently charged. If the level gets too low, thegasoline 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
To restart the climate system functions that havebeen reduced in the mode, press the AUTO ordefroster buttons.
In order to return to full functionality for all of thesystems that may be affected by Pure mode,select another drive mode or adapt the climatesystem functions using the INDIVIDUAL mode.
OFF ROAD
This mode helps maximize the vehicle's capacityto 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 streetdriving.

CAUTION
OFF ROAD drive mode may not be used ifthe 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 theOFF 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, it
also 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 activedriving.
This mode maximizes the combined effects ofthe 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.

Activating LSC
Select the Off Road drive mode to activate thefunction.
Select any other drive mode to turn it off.

NOTE
When LSC with HDC is activated by the OffRoad drive mode, the feel of the acceleratorpedal and engine response will change.
The function is deactivated when driving athigher speeds and must be reactivated atlower speeds if so desired.

All Wheel Drive (AWD)8
Your Volvo can be equipped with All WheelDrive, which means that power is distributedautomatically between the front and rear wheels.
Under normal driving conditions, most of theengine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction.
AWD reacts differently, depending on the drivemode* selected.

Suspension and leveling control*
The leveling control system adjusts the suspen-sion and shock absorbers automatically to helpprovide good comfort and control while driving.Leveling can also be controlled manually tomake loading or getting in and out of the vehicleeasier.
Pneumatic suspension and shock
absorbers
This system is linked to the selected drive modeand is adapted to the vehicle's speed. The pneu-matic suspension reduces the vehicle's groundclearance at higher speeds to reduce wind resis-tance and increase stability. The shock absorbersare normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface, acceleration, braking andcornering.
The instrument panel will indicate when the sus-pension level is being adjusted.
The level cannot be adjusted if one of the sidedoors or the hood is open.

Suspension leveling settings
Easy entry
The vehicle can be lowered to entering and exit-ing easier.
In the center display's Top view:
1.Tap Settings.
2.Tap My CarSuspension .
3.Select Easy Entry/Exit Control.
>When the vehicle is parked and theengine is turned off, the level is lowered.Level adjustment will stop if a side door isopened and will resume after a slightdelay when the door has been closed.When the engine is started and the vehi-cle begins to move, the level will be raisedto the height set by the selected drivemode.
If a door has been opened and closed, there maybe a slight delay before the leveling function willresume.

Turning off suspension and leveling control
In certain situations, this function has to beturned off, for example when lifting the vehicle ona jack to help avoid problems created by the dif-ference in levels in the pneumatic suspensionwhen the vehicle is raised.
1.Tap Settings in the center display's Topview.
2.Tap My CarSuspension .
3.Select Deactivate Suspension & LevelingControl.
Loading mode
Use the buttons in the cargo compartment toraise or lower the vehicle to make loading orunloading easier or when attaching a trailer.

Parking the vehicle
When parking, be sure that there is adequatespace above and below the vehicle since itsground clearance may vary, e.g., depending onthe ambient temperature, how the vehicle is loa-ded, if loading mode is being used or the drivemode selected after the engine is started.
The level may also be adjusted for a certain timeafter the vehicle has been parked to compensatefor possible height adjustments due to tempera-ture changes in the pneumatic suspension whenthe vehicle has cooled.
Transport
When transporting the vehicle on a ferry, train ora tow truck, it may only be secured (lashed)around the tires, not using any other chassiscomponents. Changes in the pneumatic suspen-sion may occur during transport that could nega-tively affect the lashing and result in damage.
