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.

CAUTION
The maximum trailer weights listed are onlyapplicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.
WARNING
•Bumper-attached trailer hitches must notbe used on Volvos, nor should safetychains be attached to the bumper.
•Trailer hitches attaching to the vehiclerear axle must not be used.
•Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
•When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
Trailer cable
An adapter is required if the vehicle's trailer hitchhas a 13-pin connector and the trailer has 7 pins.Use an adapter cable approved by Volvo. Makesure the cable does not drag on the ground.

Battery drain
Your vehicle's electrical functions drain the bat-tery to varying extents.
Avoid using ignition mode II as much as posssi-ble, or electrical functions that require a greatdeal of electrical current when the engine is notrunning.
Using ignition mode I whenever possible con-sumes less electrical current.
Functions that require a great deal of electricalcurrent include:
•the climate system blower
•headlights
•wipers
•infotainment system (especially at high vol-ume).
If the battery's charge level is low, a text messagewill appear in the instrument panel. The vehicle'senergy-saving function will then turn off orreduce certain functions that are currently con-suming electrical current.
If the battery needs to be recharged, start theengine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

Starting the engine
The engine can be started using the start knobon the tunnel console if there is a remote key inthe passenger compartment.
Start knob in the tunnel console between the front seats
WARNING
Before starting the engine:
•Fasten the seat belt.
•Check that the seat, steering wheel andmirrors are adjusted properly.
•Make sure the brake pedal can bedepressed completely. Adjust the seat ifnecessary.
To start the engine.
1.A remote key must be in the passenger com-partment. On models with the standardPassive Start, the key has to be in the frontsection of the passenger compartment. If thevehicle is equipped the optional PassiveEntry system (keyless locking/unlocking) thekey can be anywhere in the vehicle.
2.Press firmly on the brake pedal2.
3.Turn the start knob toward START andrelease it to start the engine.
> The starter motor will crank until theengine starts or its overheating protectionis triggered.
2If the vehicle is moving, it is only necessary to turn the start knob toward START to start the engine.

Hybrid battery charge status
The hybrid battery's charge status (level) is indi-cated by an LED light in the vehicle's chargingsocket and 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 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.
