06 Starting and driving General information more frequently and spray an anti-rust oil on the battery posts. Conserving electrical current Keep the following in mind to help minimize battery drain: NOTE • Volvo recommends the use of snow tires on all four wheels for winter driving - see the chapter "Wheels and tires." • • When the engine is not running, avoid turning the ignition key to position II. Many electrical systems (the audio system, the optional navigation system, power windows, etc) will function with the ignition key in position I. This position reduces drain on the battery. • To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 217 for the location of the washer fluid reservoir). This is important since dirt is often splashed on the windshield during winter driving, requiring the frequent use of the washers and wipers. Volvo Washer Solvent should be diluted as follows: Down to 14 °F (-10 °C): 1 part washer solvent and 4 parts water Down to 5 °F (-15 °C): 1 part washer solvent and 3 parts water Down to 0 °F (-18 °C): 1 part washer solvent and 2 parts water Down to -18 °F (-28 °C): 1 part washer solvent and 1 part water. If the ignition is switched on, a warning message will be displayed in the text window in the instrument panel when the battery charge is low. An energy conserving function designed into the vehicle's electrical system will switch off certain functions or reduce the load on the battery by, e.g., reducing the audio system's volume. • • Please keep in mind that using systems, accessories, etc that consume a great deal of current when the engine is not running could result in the battery being completely drained. Before a long distance trip It is always worthwhile to have your vehicle checked at a trained and qualified Volvo service technician before driving long distances. Your trained and qualified Volvo service technician will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for your use in the event that problems occur. As a minimum, the following items should be checked before any long trip: • The optional 12 volt socket in the trunk (certain models only) provides electrical current even with the ignition switched off, which drains the battery. 06 • Use Volvo Teflon Lock Spray in the locks. NOTE Avoid using de-icing sprays as they can cause damage to the locks. • Check that engine runs smoothly and that fuel consumption is normal. • Check for fuel, oil, and fluid leakage • Have the transmission oil level checked2. • Check condition of drive belts. 2 To prevent injury from contact with hot surfaces, do not inspect your vehicle's transmission fluid yourself. Have your vehicle's transmission fluid level inspected by a qualified Volvo service technician. 140
