Recommendations during driving

General

Economical driving

Economical driving and reducing environ-
mental impact result from driving gently with
anticipation and adapting your driving style
and speed to the current situation (for further
advice on how you can reduce environmental
impact, see page 9).
• Do not let the engine idle, but drive at light
loads as soon as it is possible.
• A cold engine consumes more fuel than a
warm one.
• Do not drive with unnecessary loads in the
05
car.
• Do not use winter tyres when the roads
are dry.
• Remove the load carrier when it is not in
use.
• Use the parking heater* in cold weather so
that the engine reaches its normal operat-
ing temperature more quickly.

Slippery driving conditions

Practise driving on slippery surfaces under
controlled conditions to learn how the car
reacts.

Driving in water

The car can be driven through water at a
maximum depth of 25 cm at a maximum
speed of 10 km/h. Extra caution should be
exercised when passing through flowing
water.
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.
Clean the electric contacts of the electric
engine block heater and trailer coupling after
driving in water and mud.
Do not let the car stand with water over the
sills for any long period of time. This could
cause electrical malfunctions.
IMPORTANT
Engine damage can occur if water enters
the air filter.
In greater depths, water can enter the trans-
mission. This reduces the lubricating ability
of the oils and shortens the service life of
the systems.
In the event of engine stop in water do not
try restart. Tow the car from the water.
Engine and cooling system
Under special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine
and cooling system will overheat. Proceed as
follows to avoid overheating the engine.
• Maintain a low speed when driving with a
trailer up long, steep ascents.
• Do not turn the engine off immediately you
stop after a hard drive.
NOTE
It is normal for the engine's cooling fan to
operate for a while after the engine has
been switched off.
• Remove any auxiliary lamps from in front
of the grille when driving in extreme high
temperatures.
• Do not exceed engine speeds of 4500 rpm
(3500 rpm for diesel engines) if driving with
a trailer or caravan in hilly terrain. The oil
temperature could become too high.
