and off
Seat ventilation can be used e.g., to help remove dampness from the seat occupant's clothing.
The ventilation system consists of fans in the seats and backrests that draw air through theseat upholstery. The cooling effect increases asthe air in the passenger compartment becomescooler. This feature can be activated when theengine is running and it monitors the seat's tem-perature, sunlight in the passenger compartmentand the ambient temperature.

Preconditioning
•If possible, precondition the vehicle with the charging 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 adequate distance 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 moreenergy-efficient than the gasoline engine,especially at lower speeds. •
In hilly terrain, put the gear selector in mode B
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.
• Select the
Save drive mode for higher
speeds when driving farther than is possible using the electric motor only.
• 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 a depth 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 water before driving through it. Take particular carewhen driving through flowing water.
• Before driving through water, always select the
Off Road drive mode to ensure that the
gasoline engine is running and to maximize ground 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 rushing water. 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.

Towing recommendations (p. 360)
Overheating the engine and transmission
In demanding driving conditions, such as when transporting 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 if there 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 will illuminate and the message
Engine

Refueling from a service station pump
To refuel:
1. Open the fuel filler door. Do not refuel withthe engine running 1
2. Insert the pump's nozzle into the fuel filler pipe's opening as far as possible (see the
illustration).
3. Avoid overfilling the fuel tank. Do not press the handle on the filler nozzle after it has stopped pumping. Too much fuel in the tankin hot weather conditions can cause the fuelto overflow. Overfilling could also cause dam-age to the emission control systems.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol can causedamage to painted surfaces, which may notbe covered under the New Vehicle LimitedWarranty.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine 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

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 great deal 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 electrical current include:
• the climate system blower
• headlights
• wipers
• infotainment system (especially at high vol- ume).
If the battery's charge level is low, a text message will 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 the engine and let it idle for at least 15 minutes ordrive the vehicle (driving charges the batteryfaster than letting the engine idle).

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.

Preparations for charging the hybrid batterySeveral preparatory steps should be taken before starting to charge the hybrid battery.WARNING
• The charging cable must be grounded when in use. It is equipped with a cordwith a grounding conductor and agrounding plug. The plug must beinserted into an appropriate outlet that isproperly installed and grounded inaccordance with all local codes and ordi-nances and is not damaged in any way
• Children should be supervised when inthe vicinity of the charging cable when itis plugged in
• High voltage is present in your electricmeter housing and power distributionservice panel. Contact with high voltagecan cause death or serious personalinjury
• Do not use the charging cable if it isdamaged in any way
• Always position the charging cable sothat it will not be driven over, stepped on,tripped over or otherwise damaged, orcause personal injury
• Disconnect the charger from the wall out-let before cleaning it
• Never connect the charging cable to anextension cord or a multiple plug socket
• If the hybrid battery needs to be replaced, this may only be done by Volvo retailer orauthorized Volvo workshop
Also, refer to the manufacturer's instructions for using the charging cable and its compo-nents.
Prior to chargingThe charging cable and any of its components should not be wet or submerged in any liquid. The charge module or its plug should not be exposed to direct sunlight. This could cause theunit's overheating protector to reduce or stop thehybrid battery charging process. Be sure the 120-/240-volt socket used has ade- quate current for charging electrically poweredvehicles. Have the socket checked by an licensedelectrician if you are uncertain.
