Rev counter The red part of the rev counter scale
1›››
Fig. 24 ››› page 30 marks the area where
the engine control unit begins to limit the en-
gine speed. The engine control unit is re-
sponsible for reducing the revs to a safe lim-
it.
Before the needle reaches the red zone
change up into a higher gear, or move the se-
lector lever of the automatic gearbox to D.
In order to drive at an optimum RPM, follow
the gear change indications ››› page 32. For the sake of the environment
Changing to higher gears in advance helps to
reduce fuel consumption and noise levels,
helps to protect the environment and benefits
both the useful life and the reliability of the
engine. Speedometer
Speed warning
An audible warning will be heard when 120
km/h (75 mph) is exceeded. If the speed falls
below this limit, the audible warning
switches off. Note
This function is only valid for certain coun-
tries. Coolant temperature gauge
The coolant temperature gauge
4
››› Fig. 24
››› page 30 only works when the ignition is
sw it
ched on.
Damage to the engine can be avoided by ob-
serving the indications regarding the temper-
ature zones.
Engine cold
If the needle is still on the left of the scale,
the engine has not yet reached operating
temperature. Avoid high engine speeds, hard
acceleration and subjecting the engine to
high loads.
Operating temperature zone
When the needle has reached the central part
of the scale, this means the engine has
reached operating temperature. Running the
engine at full throttle and the high tempera-
tures involved can cause the needle to be
positioned in the zone on the right. CAUTION
The additional headlights and other parts
placed in front of the fresh air inlets reduce
the effect of engine cooling. With high out-
side temperatures and engine speeds a risk
becomes present of the engine overheating.

warning symbol illu-
minates on the general instrument panel and
an audible warning can be heard. CAUTION
Never completely empty the tank! An irregu-
larity in the fuel supply system can cause ir-
regularities when the engine is running. Un-
burned fuel can reach the exhaust gas sys-
tem, which can cause deterioration of the cat-
alytic converter. Note
Some vehicles come fitted with the fuel
gauge on the general instrument panel. 31

38 WARNING
● Failure to observe control lamps and warn-
ing messages can result in serious personal
injuries or damage to your vehicle.
● The engine compartment is a dangerous
area. Carrying out work in the engine com- partment, i.e. checking and filling service liq-
uids, can lead to injury, scalding, burns and
fires. Therefore the corresponding warnings
must always be observed
››› page 132, En-
gine compartment. Handbrake
If the
warning lamp lights up, the hand-
br ak
e is applied. Additionally, driving the ve-
hicle at speeds exceeding 6 km/h (4 mph) for
at least 3 seconds produces an audible warn-
ing.
The informative display indicates:
Release the handbrake!
Brake system The warning lamp
illuminates if the brake
fluid level is too low or if there is a fault in the
ABS system.

Instruments and warning lamps
Go to a technical service.
Particulate filter (diesel engines)The particulate filter eliminates soot from
emissions. The particles accumulate in the
filter where they are normally burned off.
If the warning lamp
is illuminated, the fil-
ter is obstructed by soot.
In order for the filter to clean itself (if the traf-
fic conditions ››› so permit) it is essential
to drive for at least 15 minutes (or until the
warning lamp switches off) with 4th or 5th
gear engaged (automatic gearbox: position
S) at a minimum speed of 60 km/h (37 mph)
with the engine speed between
1,800-2,500 rpm.
The warning lamp switches off once the
filter has been successfully cleaned.
If the cleaning process is not successful, the
warning lamp does not switch off and the
warning lamp starts to flash.
The informative display indicates:
Diesel particulate filter. Instruction Manual!
The engine control unit allows driving to con-
tinue in an emergency program. When
switching the ignition off and on again, the
warning lamp also illuminates.
Go to a technical service. WARNING
● The particulate filter attains very high tem-
peratures. Therefore, do not park the vehicle
in places where the exhaust pipe could come
into contact with dry grass or with highly-
flammable materials. Risk of fire! CAUTION
While the warning lamp is lit up, the fuel
c
onsumption is high, and in certain condi-
tions, the engine power is reduced. Note
● In order for the particulate filter to burn off
soot in a correct manner, avoid carrying out
frequent short journeys.
● Using diesel fuel with a high sulphur count
can considerably reduce the useful life of the
particulate filter. The specialised service pro-
vides information about the countries where
fuel with a high sulphur content is used. Fuel reserve
The warning lamp illuminates when ap-
proximately only 7 litres of fuel remain in the
tank
The informative display indicates:
Refuel! Fuel range…km...(miles) Note
The message on the display switches off only
after refuelling and carrying out a short jour-
ney. Airbag system
If the warning lamp
is lit up, there is a
f au
lt in the airbag system.
The informative display indicates: Airbag fault!
The airbag system availability is controlled
electronically, regardless of whether an air-
bag is disabled.
If the front airbag, side airbag, head protec-
tion airbag or the belt tensioner are disabled
using the diagnostics system:
● After switching on the ignition, the warn-
ing lamp illuminates for about 4 seconds and
flashes for another 12 seconds.

Current fuel consumption
Current fuel consumption is indicated on the
display in litres/100 km (miles) 1)
. You can
adapt your driving style to the required con-
sumption with the assistance of this indica-
tor.
The consumption is displayed in litres per
hour while the vehicle is stopped or at idling
speed 2)
.
Average fuel consumption
The display shows the average fuel consump-
tion in litres/100 km 1)
calculated since the
memory was last reset ››› page 39.
If you wish to measure the average fuel con-
sumption for a specific period, the memory
must first be deleted ››› page 40. While driv-
ing the first 300 m after deleting the memory
this value is not shown on the display.
The value is updated regularly while the vehi-
cle is in motion.
Operating range
The approximate operating range is indicated
in kilometres (miles) on the display. It shows how far the vehicle can travel with the availa-
ble fuel using the same driving conditions as
a reference.
The operating range is calculated in sections
of 10 kilometres (miles). When the fuel
gauge enters the reserve zone, the operating
range is displayed in steps of 5 kilometres.
The operating range is calculated based on
the fuel consumption during the last 50 kilo-
metres (miles). The operating range increa-
ses when driving in a more economical man-
ner.
When the memory is reset (after disconnect-
ing the battery), the operating range is calcu-
lated with a 10 litres per 100 km consump-
tion and adjusts to represent the current driv-
ing style.
Distance
The display shows the distance you have cov-
ered since the memory was last reset
››› page 39 . If you wish to measure the dura-
tion of a j
ourney from a specific moment, the
memory must be deleted ››› page 40.
The maximum value for both memories is
1999 km (miles), or 9999 km (miles) in vehi- cles fitted with an informative display. The
memory is reset if this value is exceeded.
Average speed
The display shows the average speed in
km/h (mph) calculated from the last time the
memory was reset
››› page 39. If you wish to
mea
sure the average speed for a specific pe-
riod, the memory must first be deleted

– Unscrew the tank cap anti-clockwise and
place it on top of the tank flap ››› Fig. 107
.
– Insert the pump nozzle into the fuel feed
tube as far as it will go.
The fuel tank is full as soon as the automatic
filler nozzle cuts out ››› .
– Remove the pump nozzle from the fuel feed
tube and place it back on the pump.
– Screw the tank cap clockwise until it clicks
into place.
– Close the tank flap. Make sure you hear it
click into place.
– Check that the fuel flap is properly closed. CAUTION
● Switch off the auxiliary heater (heater and
independent heater) before filling the tank.
● The fuel tank is full as soon as the automat-
ic filler nozzle cuts out. Do not continue fill-
ing, as this will fill the expansion chamber. Note
The fuel tank capacity is around 55 litres, of
which 7 litres are the reserve. Unleaded petrol
Your vehicle must only be run on
unleaded
petrol that complies with the Standard EN
228 (in Germany, also DIN 51626 – 1, or E10
for unleaded petrol with 95 and 91 octane
rating (RON) or DIN 51626 – 2, or E5 for un-
leaded petrol with 95 and 98 RON).
Prescribed fuel – unleaded petrol (95/91
RON)
Use unleaded petrol with 95
RON. Unleaded
petrol with 91 RON can also be used, al-
though thi s
will result in a slight loss of pow-
er.
If, as an emergency measure, you have to fill
the tank with petrol with a lower RON to that
prescribed, use only moderate engine
speeds and light throttle. High engine speed
and full throttle can seriously damage the en-
gine! Fill up with petrol with the correct RON
as soon as possible.
Prescribed fuel – unleaded petrol (min. 95
RON)
Use unleaded petrol with 95 RON.
If u
nleaded petrol with 95 RON is not availa-
bl
e, you can fill up with petrol with 91 RON as
an emerg
ency measure. In this case, use only
moderate engine speeds and a light throttle.
High engine speed and full throttle can seri- ously damage the engine! Fill up with petrol
with the correct RON as soon as possible.
Petrol with a RON below
91 cannot be used,
even a
s an emergency measure. Risk of seri-
ously damaging the engine!
Unleaded petrol with higher RON
Unleaded petrol with a higher RON to that
prescribed can be used without limits.
In vehicles running on prescribed unleaded
petrol with 95/91 RON
, there is no notable
increase in power or lower fuel consumption
when petrol with a RON higher than 95
is
used.
In vehicles running on prescribed unleaded
petrol with min. 95 RON
, there is an increase
in power and a lower fuel consumption when
petrol with a RON higher than 95
is used.
Prescribed fuel – unleaded petrol (98/(95)
RON)
Use unleaded petrol with 98
RON. Unleaded
petrol with 95 RON can also be used, al-
though this will result in a slight loss of pow-
er.
If unleaded petrol with 98
or 95 RON is not
available, you can fill up with petrol with 91
RON as an emergency measure. In this case,
use only moderate engine speeds and a light
throttle. High engine speed and full throttle
can seriously damage the engine! Fill up with

Advice
● The temporary spare wheel is fitted
● One wheel on the axle has been changed
Basic system settings
Should the tyre pressure change or if one or
more wheels are changed or the position of
the wheel on the vehicle is changed, e.g.
changing round the front and rear wheels, or
where a warning lamp lights up when driv-
ing, the system must be adjusted as follows:
● Inflate all tyres to the prescribed pressures
››› page 144 .
● Sw it
ch the ignition on.
● Hold the
››› Fig. 120 button down for
at least 2 seconds. The warning lamp will
light up when the button is pressed . The
system memory is also deleted and a new
calibration process will begin, which is indi-
cated by an audible warning and the warning
lamp switching off.
● If the warning lamp remains lit and does
not switch off, not even once the basic set-
ting process is complete, this indicates a
fault in the system. Contact an Official Serv-
ice.
The warning lamp lights up
If the pressure on at least one tyre is signifi-
cantly lower than the pressure set by the driv-
er, the warning lamp ››› will light up.The warning lamp flashes
If the warning lamp flashes, there is a fault in
the system. Contact a specialised service to
have it fixed.
WARNING
● If the warning lamp lights up, slow down
immediately and avoid any severe braking or
steering manoeuvres. Stop and check the
tyres and their pressure as soon as possible.
● Under certain conditions (e.g. sporty driv-
ing style, driving on loose surfaces or in win-
ter) the warning lamp may take a while to
light up or m
ay remain switched off.
● Despite the tyre pressure monitoring sys-
tem, the driver remains responsible for main-
taining the correct tyre pressure. You must
therefore check the tyre pressure often. Note
● The tyre pressure monitoring system is not
a replacement for regularly checking the tyre
pressure, as it is unable to recognise an even
drop in pressure.
● The tyre pressure monitoring system is un-
able to warn of a sudden drop in tyre pres-
sure, e.g. a puncture. In this case, try to stop
the vehicle carefully with no severe braking
or steering manoeuvres.
● To ensure the tyre pressure monitoring sys-
tem works correctly, the basic setting must
be performed every 10 000 km (6000 miles)
or once a year. Winter service
Winter tyres Winter tyres will significantly improve han-
dling of the vehicle in winter road conditions.
The design of summer tyres (width, rubber
compound, tread pattern) gives less grip at
temperatures below +7 °C (45 °F), on ice and
snow. This applies particularly to vehicles
equipped with wide section tyres or high
s
peed ty
res (code letters H or V on the side-
wall).
In order to preserve the performance of the
vehicle as much as possible, winter tyres
must be fitted on all four wheels, the mini-
mum depth of the tread must be 4 mm and
the maximum age must be 4 years.
You can use winter tyres of a lower speed rat-
ing if the maximum speed limit of these tyres
will not be exceeded, even if the maximum
speed limit for the vehicle is higher. For the sake of the environment
Summer tyres should be fitted again in time,
as they give better handling on roads free of
snow and ice and at temperatures over +7 °C
(45 °F). Summer tyres have a shorter braking
distance, produce less rolling noise and do
not wear as quickly. They also reduce fuel
consumption. 148
