The display » Fig. 24 provides information on the engine coolant temperature.
The display only works if the ignition is switched on.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine has not yet reached its operating temperature. Avoid high speeds, full throttle
and high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale

High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too
high.
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.

WARNINGFor the vehicle systems to function correctly, and thus for safe driving,
there must be sufficient fuel in the tank. Never drain the fuel tank com-
pletely – risk of accident!
CAUTION
Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring. This can result in considerable damage to parts of the en-
gine and the exhaust system.
Note
■ After filling up, it can occur that during dynamic driving (e.g. numerous
curves, braking, driving downhill and climbing a steep hill) the fuel gauge indi-
cates approx. a fraction less. When stopping or during less dynamic driving, the
fuel gauge displays the correct fuel level again. This is not a fault.■
The arrow
next to the icon
within the fuel gauge displays the installation
location of the fuel filler on the right-hand side of the vehicle.

DriveGreen function140Radiator blind140
The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Running-in
Driving in the engine
The engine has to be run in during the first 1 500 kilometres. During this peri-
od, the driving style decides on the quality of the driving-in process.
During the first 1 000 km we recommend not driving faster than 3/4 of the
maximum permissible engine speed, not to drive at full throttle and to dis-
pense with the trailer.
In the area of 1,000 to 1,500 kilometres the engine load can be increased up
to the maximum permitted engine speed.
New tyres
New tyres must firstly be “run in”, as they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Therefore, drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Switch in an energy saving and timely manner Observe the recommended gear » page 42.
Avoid full throttle and high speeds
Fuel consumption can be reduced by half if only three-quarters of the possible
top speed of your vehicle is used.
Reducing idling
If the vehicle is fitted with the START - STOP system there is an automatic re-
duction of the idling. If the engine is stopped on vehicles without START-STOP
system, such as when waiting in a traffic jam, the fuel economy is already
greater after 30 - 40 s than the fuel quantity which is required for engine re-
start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 217.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 0.3 l/100 km. At a speed
of 100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Only turn on electrical consumers (e.g. seat, window and mirror heating and
the like) for as long as necessary.
In Infotainment, the display is shown of up to three consumers which are cur-
rently showing the highest degree of fuel consumption » Owner´s Manual In-
fotainment , chapter CAR - Vehicle settings .
Use the cooling system economically
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.139Starting-off and Driving

Radiator blind
The radiator blind(hereinafter: blind) helps to reduce CO 2emissions as well as
harmful emissions and to save fuel.
If the system detects that it is possible to reduce the amount of air flowing to
the radiator, it closes the blinds. As a result the wind resistance at the front of
the vehicle is reduced.
The blinds are located between the grille in the front bumper and the radiator.
140Driving
If the functioning of the blinds is impaired and the vehicle reaches a speed of
about 150 km/h, the following message appears in the display of the instru-
ment cluster.Error: radiator shutter. Function restricted.RADIATOR SHUTTER RESTRICT_
After displaying the above message, the speed of the vehicle is automatically
limited to about 170 km/h.
If this message appears in the winter, the cause may be ice or snow caught up
in the blinds. After the ice or snow has thawed, the blinds are functional again.
If the impairment not due to ice or snow, then assistance from a specialist
should be sought.

This section of the manual contains important information on preventing dam-
age to the vehicle while driving.
Driving Tips
Only drive on such roads and in such terrain, which match the vehicle parame-
ters » page 246 , Technical data as well as your driving skills.
The driver is always responsible for deciding whether the vehicle can handle
travelling in the given terrain.
WARNING■ Always adjust your driving to the current terrain and weather conditions.
Excessive speed or incorrect driving manoeuvres can cause damage to the
vehicle and lead to serious injuries.■
Combustible objects such as dry leaves or twigs caught under the base of
the vehicle could ignite on hot vehicle parts - risk of fire!
CAUTION■ Pay attention to the ground clearance of the vehicle! When driving over ob-
jects which are larger than the ground clearance, the vehicle can get damaged.■
Any objects that get trapped under the vehicle floor must be removed as
soon as possible. These objects can damage the fuel lines, the brake system,
seals and other parts of the vehicle.
■
Drive slowly in unknown terrain and watch out for unexpected obstacles,
such as potholes, rocks, stumps, etc.
■
Check up on confusing sections of unpaved roads before travelling on them
and consider whether such travelling is possible without risk.
Driving through water
Fig. 173
Maximum permissible water lev-
el when driving through water
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads).
›
Therefore determine the depth of the water before driving through bodies of
water.
The water level must not reach above the web of the lower beam » Fig. 173.
›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle which can
cause water to penetrate into the air induction system of the engine or into
other parts of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ Should water penetrate into the intake system of the engine, there is a
threat of serious damage being incurred by the engine parts!■
When driving through water, some vehicle parts such as chassis, electrics or
transmission can be severely damaged.
