STARTING AND DRIVING
356
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.

STARTING AND DRIVING
358•
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 bedamaged. It is therefore advisable to check the 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.

Climate system serviceService and repairs on the air conditioning sys- tem should only be done by a trained and quali-fied Volvo service technician.
Troubleshooting and repairsThe air conditioning system contains a floures- cent tracer substance. Ultraviolet light is used tosearch for leaks in the system.
Refrigerant R134a
WARNING
The air conditioning system contains the refrigerant R134a under pressure. Serviceand repairs on the system should only bedone by a trained and qualified Volvo servicetechnician.

Start battery
The vehicle's electrical system is single pole and uses the body and engine block as conductors. The start (main) battery is used to power electri- cal components and systems. However, thehybrid battery is used to start the gasolineengine. The start battery should only be replaced by a trained and qualified Volvo service technician.
The start battery is an Absorbed Glass Mat (AGM) 12-volt battery that is dimensioned foruse in vehicles to support electrical systems andfunctions. The service life of a battery is affected by factors such as driving conditions/style, the number ofstarts, climate, etc. Extreme cold may also furtherdecrease the battery

Hybrid battery specifications
The hybrid battery is used to power the electric motor for the rear wheels when the gasolineengine is not being used.
Type: lithium-ion
Power reserve: 9.2 kWh
NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
