Preconditioning
Preconditioning the vehicle before driving canhelp reduce wear and reduce energy consump-tion during a trip.
NOTE
Full preconditioning is only possible when thevehicle's charging cable is connected.
In other cases, the passenger compartmentcan be cooled for 3 minutes in warm weather.This function is started from the Parkingclimate tab in the center display's Climateview.
With the charging cable connected, precondition-ing can be started immediately or a timer functioncan start this procedure at a later time.
This feature utilizes several of the vehicle's sys-tems:
•The High Voltage Coolant Heater (HVCH)warms the hybrid battery and passengercompartment in cold weather.
•In warm weather, the ventilation system willattempt to cool the passenger compartmentto the current ambient temperature.
•In warm weather, the air conditioning systemwill cool the passenger compartment to acomfortable temperature.
•The electrically heated steering wheel andseats can be activated.
•Heating for the windshield, tailgate windowand door mirrors can be activated.
If preconditioning is used in warm weather, a cer-tain amount of water may condense under thevehicle, which is normal.
When preconditioning is used, this system willattempt to establish a comfortable temperature inthe passenger compartment but not necessarilythe temperature currently set in the climatesystem.
Maintaining a comfortable passenger
compartment climate
The climate in the passenger compartment canbe maintained even when the vehicle is parkedand the engine is turned off (e.g., if anyoneintends to remain in the vehicle).
This function can only be direct-started.
This function utilizes several of the vehicle's sys-tems:
•Residual heat from the engine is used helpkeep the passenger compartment warm incool temperatures.
•In warm weather, the ventilation system willattempt to cool the passenger compartmentto the current ambient temperature.
This function will not be activated if the vehicle islocked from the outside in order to avoid using
residual engine heat unnecessarily. This functionis primarily intended for use when the engine isnot running but someone remains in the vehicle.

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.

•The air conditioning may be switched offtemporarily.
•After a prolonged period of driving, do notturn off the engine immediately after stop-ping.
•The engine cooling fan commonly continuesto run for several minutes after the enginehas been turned off.
WARNING
The cooling fan (located at the front of theengine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.

Winter driving
Check your vehicle before the approach of coldweather.
The following advice is worth noting:
•Make sure that the engine coolant contains50 percent antifreeze. Any other mixture willreduce freeze protection. This gives protec-tion against freezing down to –31 °F(–35 °C). The use of "recycled" antifreeze isnot approved by Volvo. Different types ofantifreeze must not be mixed.
•Volvo recommends using only genuine Volvoantifreeze in your vehicle's radiator.
•Try to keep the fuel tank well filled – thishelps prevent the formation of condensationin the tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
•The viscosity of the engine oil is important.Oil with low viscosity (thinner oil) improvescold-weather starting as well as decreasingfuel consumption while the engine is warm-ing up. Full synthetic 0W-30 oil is recom-mended for driving in areas with sustainedlow temperatures.
•The load placed on the battery is greater dur-ing the winter since the windshield wipers,lighting, etc., are used more often. Moreover,the capacity of the battery decreases as thetemperature drops. In very cold weather, apoorly charged battery can freeze and be
damaged. It is therefore advisable to checkthe state of charge more frequently andspray an anti-rust oil on the battery posts.
•Volvo recommends the use of snow tires onall four wheels for winter driving.
•To prevent the washer fluid reservoir fromfreezing, add washer solvents containingantifreeze. This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Solventshould be diluted as follows: Down to 14 °F(–10 °C): 1 part washer solvent and 4 partswater Down to 5 °F (–15 °C): 1 part washersolvent and 3 parts water Down to 0 °F(–18 °C): 1 part washer solvent and 2 partswater Down to –18 °F (–28 °C): 1 partwasher solvent and 1 part water.
•Use Volvo Teflon Lock Spray in the locks.
•Avoid using de-icing sprays as they cancause damage to the locks.

Driving with a trailer
When towing a trailer, always observe the legalrequirements of the state/province.
•All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
•Increase tire pressure to recommended fullpressure.
•When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
•Maximum speed when towing a trailer:50 mph (80 km/h).
•Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
•If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
•Avoid overload and other abusive operation.
•Hauling a trailer affects handling, durability,and economy.
•It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
•Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
•More frequent vehicle maintenance isrequired.
•Remove the ball holder when the hitch is notbeing used.
NOTE
•When parking the vehicle with a trailer ona hill, apply the parking brake before put-ting the gear selector in P. Always followthe trailer manufacturer's recommenda-tions for wheel chocking.
•When starting on a hill, put the gearselector in D before releasing the parkingbrake.
•If you use the manual (Geartronic) shiftpositions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
•The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
•Avoid driving with a trailer on inclines ofmore than 15%.
MAINTENANCE AND SERVICING

NOTE
If the start battery is completely dischargedand the vehicle has no normal electrical func-tions, and the engine is then started using anauxiliary battery or battery charger, theStart/Stop function will be activated. Theengine can then be auto-stopped but may notauto-start again due to an insufficient chargelevel in the start battery.
To help ensure auto-start, the start batteryshould be charged first. At a temperature ofapprox. 60 °F (15 °C), the battery should becharged for at least 1 hour, preferably usingan external battery charger. At lower tempera-tures, the battery should be charged for3–4 hours.
If a charger is not available, it is advisable todisable the Start/Stop function until the bat-tery is sufficiently recharged.

Refilling coolant
Coolant helps keep the gasoline engine at theproper operating temperature. The heat transfer-red from the engine to the coolant can be usedto warm the passenger compartment.
When refilling coolant, follow the instructions onthe package and use the recommended amountof coolant. Never fill the cooling system withwater only; this could lead to freezing, corrosionand engine damage.
WARNING
If the engine has been running, the coolantwill be very hot. Allow the engine to coolbefore opening the coolant expansion tank. Ifthis is not possible, open the cap very slowlyto allow pressure to dissipate.
Coolant expansion tank
Lift the rubber strip by pressing it inward inthe engine compartment.
Remove the plastic cover by folding out thecatch and lifting the cover upward.
Unscrew the expansion tank cap and addcoolant. The level should be between theMIN and MAX marks on the tank.
Put the other components back in place in thereverse order.
CAUTION
•High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.
•Only use coolants with corrosion protec-tion recommended by Volvo.
•The ratio of coolant to water is 50/50.
•Mix the coolant with tap water of drinka-ble quality.
•If maintenance is performed on the cool-ing system or if the coolant is replaced,flush the cooling system with clean waterbefore adding new a new coolant/watermixture.
•The engine may only be operated with aproperly filled cooling system. Otherwise,high temperatures and cracks in the cyl-inders may occur.
