Winter driving
For winter driving it is important to perform cer- tain checks of the car in order to ensure that itcan be driven safely.
Check the following in particular before the cold season:
• The engine coolant must contain 50% glycol.This mixture protects the engine againstfrost erosion down to approximately –35 °C.To avoid health risks, different types of glycolmust not be mixed.
• The fuel tank must be kept filled to preventcondensation.
• Engine oil viscosity is important. Oils withlower viscosity (thinner oils) facilitate startingin cold weather and also reduce fuel con-sumption while the engine is cold. Readmore about suitable oils in the section"Adverse driving conditions for engine oil".
IMPORTANT
Low viscosity oil must not be used for hard driving or in hot weather.
• The condition of the starter battery and charge level must be inspected. Coldweather places great demands on the starter battery and its capacity is reduced by thecold.
• Use washer fluid with antifreeze to avoid iceforming in the washer fluid reservoir.
Slippery driving conditionsTo achieve optimum roadholding Volvo recom-mends using winter tyres on all wheels if there isa risk of snow or ice.
NOTE
The use of winter tyres is a legal requirement in certain countries. Studded tyres are notpermitted in all countries.
Practise driving on slippery surfaces under con- trolled conditions to learn how the car reacts.
