Operation
Normal temperature
If in norm
al operations, the diodes light up
until the central zone, it means that the en-
gine has reached operating temperature. At
high outside temperatures and when making
the engine work hard, the diodes may contin-
ue lighting up and reach the upper zone. This
is no cause for concern, provided the control
lamp does not light up on the instrument
panel digital display.
Heat range
When the diodes light up in the upper area of
the display and the control lamp appears
on the instrument panel display, the coolant
temperature is excessive ››› page 286. CAUTION
● To en
sure a long useful life for the engine,
avoid high revs, driving at high speed and
making the engine work hard for approxi-
mately the first 15 minutes when the engine
is cold. The phase until the engine is warm al-
so depends on the outside temperature. If
necessary, use the engine oil temperature*
››› page 34 as a guide.
● Additional lights and other accessories in
front
of the air inlet reduce the cooling effect
of the coolant. At high outside temperatures
and high engine loads, there is a risk of the
engine overheating.
● The front spoiler also ensures proper distri-
bution of
the cooling air when the vehicle is moving. If the spoiler is damaged this can re-
duc
e the c
ooling effect, which could cause
the engine to overheat. Seek specialist assis-
tance. Fuel level

The capacity of the fuel tank of your vehicle is
given in the Technical data section
››› page 48. CAUTION
Never run the fuel tank completely dry. An ir-
r e
gular fuel supply could cause misfiring. In
this way the unburned fuel can reach the ex-
haust system, which could cause the catalytic
converter to overheat resulting in damage. Control lamps
W arnin
g and control lamps Read the additional information carefully
› ›
› page 38.
The control and warning lamps are indicators
of warnings, ››› , faults
››
› or certain func-
tion s.
Some control and warning lamps come
on when the ignition is switched on, and
switch off when the engine starts running, or
while driving.
Depending on the model, additional text
messages may be viewed on the instrument
panel display. These may be purely informa-
tive or they may be advising of the need for
action ›››
page 102, Instruments.
Depending upon the equipment fitted in the
vehicle, instead of a warning lamp, some-
times a symbol may be displayed on the in-
strument panel.
When certain control and warning lamps are
lit, an audible warning is also heard.

Operation
WARNING
Never programme the auxiliary heater so that
it sw
itches itself on and is running in an en-
closed space or an area with no ventilation.
The auxiliary heater exhaust fumes contain
carbon monoxide, an odourless and colour-
less toxic gas. Carbon monoxide can cause
people to lose consciousness. It can also
cause death. Operating instructions
The auxiliary heater exhaust system located
belo
w the
vehicle must be kept clear of snow,
mud and other objects. The exhaust fumes
must be able to exit freely. The emissions
generated by the auxiliary heater are re-
moved via an exhaust pipe fitted underneath
the vehicle.
On heating the vehicle interior, depending on
the outside temperature, the warm air is first
directed at the windscreen and then to the
rest of the vehicle interior through the air
vents. Directing the diffusers – towards the
windows for example – can affect air distribu-
tion.
When will the auxiliary heater not be activa-
ted?
● The auxiliary heater requires about as
muc h po
wer as the dipped beam headlights.
If the 12-volt battery charge is too low, the auxiliary heater switches off automatically
and c
annot
be switched on. This avoids prob-
lems when starting the engine.
● The heating must be activated every time
you w
ant to set off. Similarly, the departure
time must reactivate each time.
● The control lamp (fuel
level indicator)
lights up. Note
● Noi se
s will be heard while the auxiliary
heater is running.
● When the air humidity is high and the in-
side t
emperature low, condensation from the
heating and ventilating system may evapo-
rate when the auxiliary heater is switched on.
In this case, steam may be released from un-
derneath the vehicle. This does not mean
that there is a vehicle malfunction.
● If the vehicle is tilted, e.g. if parked on a
slope, the oper
ation of the auxiliary heater
may be restricted if the fuel tank level is low
(just above the reserve level).
● If the auxiliary heater is used a number of
times
for a long period of time, the 12-volt
battery will lose its charge. To recharge the
battery, the vehicle must be driven for a num-
ber of kilometres from time to time. As a
guideline: The journey should last approxi-
mately as long as the heater was connected.
● At temperatures below +5°C (+41°F), the
auxi
liary heater may switch itself on automat-
ically when the engine is switched on. The auxiliary heater is switched off again after a
c
er
tain time.164
Checking and refilling levels
result, unburnt fuel could enter the exhaust
sy
s
tem and damage the catalytic converter.
● When filling the fuel tank after having run it
comp
letely dry on a vehicle with a diesel en-
gine, the ignition must be switched on for at
least 30 seconds before starting the engine.
When you then start the engine it may take
longer than normal (up to one minute) to
start firing. This is because air needs to be
bled from the fuel system while starting. For the sake of the environment
Do not overfill the fuel tank, it may cause the
f uel
to overflow if it becomes warm. Note
There is no emergency mechanism for the
m anua
l release of the fuel tank flap. If neces-
sary, request assistance from specialised per-
sonnel. Note
Diesel vehicles are fitted with a protective de-
v ic
e that prevents the insertion of the wrong
fuel hose 1)
. It is only possible to refuel with
Diesel nozzles.
● If the pump nozzle is worn, damaged, or if
it i
s very small, it is possible that it will not
be able to open the protective device. Before
trying to insert the pump nozzle by turning it, try a different pump or request specialist
help
.
● If
you fill the tank from a reserve fuel canis-
ter
, the protective device will not open. One
way to resolve this is to pour the fuel in very
slowly. Fuel
Ty
pes of petrol The correct grade of petrol is listed inside the
f
uel
tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded pet-
rol. The petrol must comply with European
Standard EN 228 or German standard DIN
51626-1 and must be unleaded. You can re-
fuel with a maximum ethanol proportion of
10 % (E10). The types of petrol are differenti-
ated by their octane rating (RON).
The following titles appear on the corre-
sponding adhesive on the fuel tank flap: Super unleaded 95 octane or normal 91 oc-
tane u
nleaded petrol
We recommend you use super 95 octane pet-
rol. If this is not available: normal 91 octane
petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95
octanes
You should use super petrol with a minimum
of 95 octanes.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible.
Super unleaded 98 octane or super 95 oc-
tane unleaded petrol
We recommend you use super plus 98 octane
petrol. If this is not available: super 95 oc-
tane petrol, with a slight decrease in power.
If super is not available, in an emergency you
may refuel with normal 91 octane petrol. In
this case only use moderate engine speeds
and a light throttle. Refuel with super as soon
as possible. »1)
