STARTING AND DRIVING
}}
361
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.
