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

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.

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.

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.

• 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.

IMPORTANT

Engine damage can occur if water enters

the air filter.

In depths greater than 25 cm, water could

enter the transmission. This reduces the lu-

bricating 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.

NOTE

It is normal for the engine’s cooling fan to

operate for a while after the engine has

been switched off.
