Recommendations during driving

Winter driving

Check the following in particular before the
cold season:
• The engine coolant must contain at least
50% glycol. This mixture protects the
engine down to approximately –35 °C. To
achieve optimum antifreeze protection,
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 start-
ing in cold weather and also reduce fuel
consumption while the engine is cold. For
05
more information on suitable oils, see
page 227.
IMPORTANT
Low viscosity oil must not be used for hard
driving or in hot weather.
• The condition of the battery and charge
level must be inspected. Cold weather
places great demands on the battery and
its capacity is reduced by the cold.
• Use washer fluid to avoid ice forming in
the washer fluid reservoir.

To achieve optimum roadholding Volvo rec-
ommends using winter tyres on all four
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 certain countries.
Slippery driving conditions
Practise driving on slippery surfaces under
controlled conditions to learn how the car
reacts.
