Winter driving

For winter driving it is important to perform cer-
tain checks of the car in order to ensure that it
can be driven safely.
Check the following in particular before the cold
season:
•
The engine coolant must contain 50% glycol.
This mixture protects the engine against
frost down to approx. -35°C (-31°F). To avoid
health risks, different types of glycol must not
be mixed.
•
The fuel tank must be kept filled to prevent
condensation.
•
Engine oil viscosity is important. Oils with
lower viscosity (thinner oils) facilitate starting
in cold weather and also reduce fuel con-
sumption while the engine is cold.
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. Cold
weather places great demands on the starter
battery and its capacity is reduced by the
cold.
•
Use washer fluid with antifreeze to avoid ice
forming in the washer fluid reservoir.
STARTING AND DRIVING
Slippery driving conditions
To achieve optimum roadholding Volvo recom-
mends using winter tyres on all wheels if there is
a risk of snow or ice.
NOTE
The use of winter tyres is a legal requirement
in certain countries. Studded tyres are not
permitted in all countries.
Practise driving on slippery surfaces under con-
trolled conditions to learn how the car reacts.
