Winter driving
Slippery driving conditions
Driving in water
To achieve optimum roadholding Volvo recom-
mends using winter tyres on all wheels if there
is a risk of snow or ice.
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:
Wading means the car being driven through
water e.g. on a flooded road. Driving in water
must be performed with great caution.
The car can be driven through water to a maxi-
mum depth of 45 cm (17 inches) at no more
than walking speed. Extra caution should be
exercised when passing through flowing
water.
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 use of winter tyres is a legal require-
ment in certain countries. Studded tyres
are not permitted in all countries.
During driving in water, maintain a low speed
and do not stop the car. When the water has
been passed, depress the brake pedal lightly
and check that full brake function is achieved.
Water and mud for example can make the
brake linings wet resulting in delayed brake
function.
Practise driving on slippery surfaces under
controlled conditions to learn how the car
reacts.
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.

Do not let the car stand with water over
the sills for any long period of time - this
could cause electrical malfunctions.

Use washer fluid with antifreeze to avoid
ice forming in the washer fluid reservoir.

STARTING AND DRIVING
Opening and closing the fuel filler
flap
Filling fuel
The fuel tank is fitted with a coverless fuel
filler system.
Engine damage can occur if water
enters the air filter.
•
•
The car must be unlocked for the fuel filler
flap to be opened19
.
Refuelling the car at a petrol station
If water enters the transmission, it
reduces the lubricating ability of the oil,
which shortens the service life of rela-
ted systems.
In the driver display, the
arrow next to the tank symbol
indicates which side of the
car the fuel filler flap is
located.
Damage to any component, engine,
transmission, turbocharger, differential
or its internal components caused by
flooding, hydrostatic locking or oil
shortage, is not covered by the war-
ranty.
•
•
1. Open the fuel filler flap with a gentle press
on the rear of the flap.
2. After refuelling is finished - close the flap
with a gentle press.
In the event of the engine stalling in
water, do not try restart - tow the car
from the water to a workshop - an
authorised Volvo workshop is recom-
mended. Risk of engine breakdown.

It is important to feed the pump nozzle past the filler
pipe's two openable hatches before starting to fuel
the car.
