Preconditioning
•If possible, precondition the vehicle with thecharging cable before driving.
•Avoid parking the vehicle so that the passen-ger compartment becomes too hot or cold.Park, if possible, in a climate controlled park-ing garage.
•For short drives after using the precondition-ing function, turn off the climate systemblower if possible.
•If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.

Driving
•Choose the Pure drive mode to help mini-mize electric power consumption.
•Maintain a constant speed and an adequatedistance to the vehicle ahead to minimizeuse of the brakes.
•Brake as gently as possible; doing socharges the hybrid battery using the inte-grated regenerative braking function.
•Balance energy requirements using theaccelerator pedal and utilize the gauge onthe instrument panel to see the amount ofpower available from the electric motor. Thishelps avoid starting the gasoline engineunnecessarily. The electric motor is more
energy-efficient than the gasoline engine,especially at lower speeds.
•In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.
•Higher speeds increase energy consumptionand the vehicle's wind resistance increasesalong with speed. Do not exceed postedspeed limits.
•Avoid carrying unnecessary items (extra load)in the vehicle.
•Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold).
•Remove snow tires when threat of snow orice has ended.
•Note that roof racks, ski racks, etc, increaseair resistance and also energy consumption.
•Avoid driving with open windows.

Handling and roadholding
•Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so thatcapacity weight or maximum permissible axleloads are not exceeded.
•At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned more
than might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.

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.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certainengine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
•Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
•Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
•Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components
or location or removing components, and/orrepeated use of leaded fuel.

NOTE
Unleaded fuel is required for vehicles withthree-way catalytic converters.

Heated oxygen sensors
The heated oxygen sensors monitor the oxygencontent of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

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).

NOTE
After a cold start, idle speed may be noticea-bly higher than normal for a short period. Thisis done to help bring components in theemission control system to their normal oper-ating temperature as quickly as possible,which enables them to control emissions andhelp reduce the vehicle's impact on the envi-ronment.

CAUTION
•When starting in cold weather, the auto-matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
•Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
•The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
•Selecting P or N when idling at a stand-still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.
