Winter driving
For winter driving it is important to perform
certain 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 pre-
•
vent condensation.
Engine oil viscosity is important. Oils with
•
lower viscosity (thinner oils) facilitate star-
ting in cold weather and also reduce fuel
consumption 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.
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 require-
ment in certain countries. Studded tyres
are not permitted in all countries.
Practise driving on slippery surfaces under
controlled conditions to learn how the car
reacts.
