Before a long distance trip
It is always worthwhile to have your vehicle checked 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 be checked 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 (including the sparetire where applicable), and replace those thatare worn. Also, check tire inflation pressure.
• 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 by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Driving economically with Twin EnginePlug-in Hybrid vehicles
Plan your driving in order to utilize the electric motor as much as possible. An energy-conserving driving style lowers current consumption from the hybrid battery and helpsincrease electric driving range.
Charging
• Charge the hybrid battery as often as possi- ble from the electricity grid using the charg-ing cable. Whenever possible, begin a drivewith a fully charged battery.
• Check the location of charging points.
• Where possible, choose parking spaces withcharging points.

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.
• 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. See also the arti-cle "Hybrid-related symbols and messages". •
Brake as gently as possible; doing socharges the hybrid battery. There is a regen-erative function in the brake pedal which canbe augmented by the electric motor's brakingcapacity when the gear selector is in mode B
.
• Higher speeds increase energy consumption and the vehicle's wind resistance increasesalong with speed. Do not exceed postedspeed limits.
• 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.
• Use the
Hold function at highway speeds
when traveling farther than is possible using the hybrid battery's capacity.
• Whenever possible, avoid using the
Chargefunction to charge the hybrid battery. Charg- ing the battery using the gasoline engineincreases fuel consumption and carbon diox-ide emissions.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold).
• Use tires recommended by Volvo for yourvehicle.
• 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 morethan 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 at its deepest point before driving through it.Take particular care when driving throughflowing 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.

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 recommendations
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
Towing your vehicle behind another vehicle
Twin Engine Plug-in Hybrid vehicles may not be towed behind another vehicle. Doing so woulddamage the electric motor and the three-way cat-alytic converter. If the vehicle cannot be drivenand must be moved, it must be lifted onto a flat-bed tow truck. If a Twin Engine Plug-in Hybrid vehicle is used to tow (pull) another vehicle, select the
AWD drive
mode. This helps charge the hybrid battery and improves the vehicle's road holding characteris-tics.
Tow trucks
CAUTION
In certain conditions, the towing eyelet may be used to pull the vehicle onto aflatbed tow truck.
• The vehicle's position and ground clear-ance determine if it can be pulled up ontoa flatbed tow truck using the towing eye-let.

Fuel Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (detergent
additives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddrivability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter- nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle's filler inlet. It is unlawful to dispense lea-ded fuel into a vehicle labeled "unleaded gaso-line only". Leaded gasoline damages the three-way catalytic converter and the heated oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicle
