PreconditioningPreconditioning the vehicle before driving can help reduce wear and reduce energy consump-tion during a trip.
NOTE
Full preconditioning is only possible when the vehicle's charging cable is connected. In other cases, the passenger compartment can be cooled for 3 minutes in warm weather. This function is started from the
Parking
climate tab in the center display's Climate
view.
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 will attempt to establish a comfortable temperature in the passenger compartment but not necessarily
the temperature currently set in the climate system .
Maintaining a comfortable passenger compartment climate
The climate in the passenger compartment can be 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.

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
temperature/Stop safely will be displayed.
Stop the vehicle as soon as possible in a safe place and let the engine idle for severalminutes.
• If the message
Engine temperature/High
temperature Turn off engine or Engine
coolant/Stop safely is displayed, stop
safely and turn off the engine.
• If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol will illuminate and the message

or Transmission warmStop safely, wait
for cooling will be displayed in the instru-
ment panel. •
The air conditioning may be switched off temporarily.
• 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 the engine 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 cold weather.
The following advice is worth noting:
• Make sure that the engine coolant contains 50 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.

Towing eyelet
When used, the towing eyelet should always be securely attached in the opening on the rightside of the rear bumper. There is a cover overthe attachment point.
Using the towing eyelet
Take out the towing eyelet, which is stored under the floor in the cargo compartment.

Driving with a trailer
When towing a trailer, always observe the legal requirements 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.

Refilling coolantCoolant helps keep the gasoline engine at the proper 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 on the 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 coolant will 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 in the engine compartment.
Remove the plastic cover by folding out the catch and lifting the cover upward.
Unscrew the expansion tank cap and add coolant. The level should be between the MIN and MAX marks on the tank.
Put the other components back in place in the reverse order.
CAUTION
• High levels of chlorine, chlorides and other 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.
