STARTING AND DRIVING
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.
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.
See the separate section for engine oil recom-
mendations.

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.

Driving in water
Wading means the car being driven through
water e.g. on a flooded road. Driving in water
must be performed with great caution.
Observe the following to prevent damage to
the car when driving through water:
The water level must not be higher than
•
the floor of the car. If possible, check the
depth at the deepest point before starting
to drive through the water. Extra caution
should be exercised when passing
through flowing water.
Always change to Off Road
•
before driving through water in order to
ensure that the internal combustion
engine is running.
Do not drive faster than walking pace.
•
Do not stop the car in the water. Drive for-
•
ward carefully or reverse the car back out
of the water.
Remember that waves created by oncom-
•
ing traffic may rise above the level for the
floor of the car.
Avoid driving through salt water (corrosion
•
risk).
