well as decreasing fuel consumption while the engine is warming up. For winter use, 5W- 30 oil, particularly the synthetic type1 , is recommended. Be sure to use good quality oil but do not use cold-weather oil for hard driving or in warm weather. See section "Engine oil" for more information. The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc. are used more often. Moreover, the capacity of the battery decreases as the temperature drops. In very cold weather, a poorly charged battery can freeze and be damaged. It is therefore advisable to check the state of charge more frequently and spray an antirust oil on the battery posts. Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels and tires." To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 195 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 Use Volvo Teflon Lock Spray in the locks. 1 Synthetic oil is not used when the oil is changed at the normal maintenance service intervals. NOTE Avoid the use of de-icing sprays as they can cause damage to the locks. W - Winter/Wet driving mode - enhanced vehicle traction (automatic transmission) Mode W will only function if the gear selector is in the D position. Press the button at the base of the gear selector to engage/disengage this driving mode. An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument panel (see page 48). This mode may be selected for starting/moving off on slippery roads. 150 06 Starting and driving Before a long distance trip It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before driving long distances. Your retailer or 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: Check that engine runs smoothly and that fuel consumption is normal. Check for fuel, oil, and fluid leakage. Check transmission oil level 1 . Check condition of drive belts. Check state of the battery's charge. Examine tires carefully (the spare tire as well), and replace those that are worn. Check tire pressures. The brakes, front wheel alignment, and steering gear should be checked by a trained and qualified Volvo service technician only. Check all lights, including high beams. Reflective warning triangles are legal requirement in some countries.
