Before a long distance trip
It is always worthwhile to have your vehiclechecked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should bechecked before any long trip:
•Check that engine runs smoothly and thatfuel consumption and the oil level are normal.
•Before leaving on a trip, fill the fuel tank andmake sure the hybrid battery is fully charged.During the trip, make a habit of refueling reg-ularly.
•Check for fuel, oil, and fluid leakage.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully and replace thosethat are worn. Also, check tire inflation pres-sure.
•The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
•Check all lights, including high beams.
•Reflective warning triangles are legallyrequired in some states/provinces.
•Have a word with a trained and qualifiedVolvo service technician if you intend to drive
in countries where it may be difficult toobtain the correct fuel.
•Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained bythinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.

Driving economically with the XC90 T8
Twin Engine Plug-in Hybrid
Plan your driving in order to utilize the electricmotor as much as possible.
An energy-conserving driving style lowers currentconsumption from the hybrid battery and helpsincrease electric driving range.

Charging
•Charge the hybrid battery regularly using thecharging cable. Whenever possible, begin adrive with a fully charged battery.
•Check the location of charging points.
•Where possible, choose parking spaces withcharging points.

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.

•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.
