Tips for winter operation
Engine oil Cooling fluid
Door and window seals
Before the onset of the colder weather, have
the engine filled with oil of the correct visco-
sity. See chapter on "filling capacities".
Battery
The battery capacity drops with lower tem-
peratures, but the demands made upon the
battery generally increase. Therefore, have
the battery checked and charged, if neces-
sary, in good time. Also have the acid con-
tent checked, and the terminals greased.
See chapter "Check and care of battery".
Corrosion protection
The salt spread on winter roads can have a
detrimental effect on your car's bodywork.
You should therefore wash the car as often
as convenient in accordance with our care
instructions. Have a preservative applied
and the underseal checked in an authorized
workshop before and after the cold weather
season.
The vehicle should not be driven without
anti-freeze at temperatures below freezing
point. The all-season cooling fluid in the
cooling system, put in by the manufacturer,
offers protection down to - 3 0 ° C (Northerly
lands -40°C).
Nevertheless it is advisable to have the cool-
ing fluid checked to make sure that the ne-
cessary protection is afforded, at the onset
of colder weather. When necessary, top up
with antifreeze. For amounts see chapter
"Filling capacities".
To prevent the freezing of the rubber seals
on the doors and hood top, they should be
treated with talcum powder or glycerine.
Brakes
After driving for extended periods on salt
covered roads a film can form on the brake
discs and pads which considerably reduces
friction and thus the braking effect.
Door locks
To prevent the door locks freezing up, the
lock cylinders should be masked when
washing the vehicle, to avoid ingress of
water. Should however the locks still freeze
up, a proprietory de-icing solution can be
used to free them. A warmed-up key can
also be useful, but never use force.
