WARNING
● Always keep your attention on driving! As the driver, you have the full
responsibility for the safety of traffic.
● Never use the instrument panel controls when the vehicle is in mo-
tion. Do so only when the vehicle is stopped!
Rev counter
The red part of the rev counter scale 1 ⇒ Fig. 31 ⇒
page 55 marks the zone
where the engine control unit begins to limit the engine speed. The engine
control unit is responsible for reducing the revs to a safe limit.
Before the needle reaches the red zone change up into a higher gear, or
move the selector lever of the automatic gearbox to D.
In order to drive at an optimum RPM, respect the gear change indications

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 on exceeding 120 km/h (75 mph). If the
speed falls below this limit, the audible warning switches off.
Note
This function is only valid for certain countries.
Coolant temperature gauge
The coolant temperature gauge 4
⇒ Fig. 31
⇒ page 55 only works when
the ignition is switched on.
Damage to the engine can be avoided by observing the indications regard-
ing the temperature 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
submitting 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 throt- tle and the high temperatures involved can cause the needle to be posi-
tioned in the zone on the right.
CAUTION
The additional headlights and other parts placed in front of the fresh air in-
lets reduce the effect of engine cooling. With high outside temperatures
and engine speeds a risk becomes present of the engine overheating
⇒ page 68, Coolant level and temperature .
Fuel gauge
The fuel gauge 7 ⇒ Fig. 31 ⇒
page 55 operates only when the ignition is
switched on.
The fuel tank has a capacity of approx. 55 litres. When the needle reaches
the reserve area, the warning symbol ⇒ page 71 lights up on the gener-
al instrument panel and an audible warning can be heard.
CAUTION
Never completely empty the tank! An irregularity in the fuel supply system
can cause irregularities when the engine is running. Unburned fuel can
reach the exhaust gas system, which can cause deterioration of the catalytic
converter.
Note
Some vehicles come fitted with the fuel gauge on the general instrument
panel.

Controls and displays
Current fuel consumption
The current fuel consumption is indicated on the display in litres/100km
(miles) 1)
. You can adapt your driving style to the required consumption with
the assistance of this indicator.
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 consumption in litres/100km (miles) 1)
calculated since the memory was last reset ⇒ page 59.
If you wish to measure the average fuel consumption from a specific period,
the memory must first be deleted by pressing the button, B
⇒ Fig. 34
⇒ page 60. While driving the first 300 m after deleting the memory this val- ue is not shown on the display.
The value is updated regularly while the vehicle 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 available 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
sections of 5 kilometres (miles).
The operating range is calculated based on the fuel consumption during the
last 50 kilometres (miles). The operating range increases when driving in a
more economical manner. When the memory is reset (after disconnecting the battery), the operating
range is calculated with a 10 litres per 100 km (miles) consumption and ad-
justs to represent the current driving style.
Distance
The display shows the distance you have covered since the memory was last
reset
⇒ page 59. If you wish to measure the duration of a journey from a
specific moment, the memory must be deleted by pressing the button, B
⇒ Fig. 34 ⇒
page 60.
The maximum value for both memories is 1999 km (miles), or 9999 km
(miles) in vehicles 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 59. If you wish to measure the aver-
age speed from a specific period, the memory must first be deleted by
pressing the button, B
⇒ Fig. 34 ⇒
page 60.
While driving the first 300 m after deleting the memory this value is not
shown on the display.
The value is updated regularly while the vehicle is in motion.
Driving speed
The current driving speed, the same as indicated on the speedometer, is
shown on the display 3
⇒ Fig. 31 ⇒
page 55.
Oil temperature
If the oil temperature is lower than 50 °C (+122 °F) or if a fault appears on
the oil temperature control, in place of the temperature indication, the sign -
-.- is shown.
1)
The indication of consumption is given in kms (miles)/litres in models for certain countries.
2) The indication of the consumption when the vehicle is stationary is given in - -.- kms
(miles)/litres. in models for certain countries.

WARNING
● Failure to observe control lamps and warning 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 compartment, i.e. checking and filling service liquids, can
lead to injury, scalding, burns and fires. Therefore the corresponding
warnings must always be observed ⇒ page 173, Engine compartment.
Handbrake
If the
warning lamp lights up, the handbrake is applied. Additionally,
driving the vehicle at speeds exceeding 6 km/h (4 mph) for at least 3 sec-
onds produces an audible warning.
The informative display indicates:
Release the handbrake!
Brake system
The warning lamp lights up if the brake fluid level falls too low or if there
is a fault in the ABS system.
The informative display indicates:
Brake fluid Instruction Manual!
Stop the vehicle, switch off the engine and check the level of the brake fluid
⇒ page 181
WARNING
● If the vehicle has to be stopped for technical reasons, park it a safe
distance away from moving traffic, switch off the engine and turn on the
hazard warning lights ⇒ page 98.
● The following indications must be taken into account when opening
the engine compartment to check the brake fluid ⇒ page 173, Engine
compartment.
71
Controls and displays
If the warning lamp starts to flash while driving, there is a fault in the
engine power control electronic system. The engine control unit allows driv-
ing to continue in an emergency program.
Seek professional help.
Engine management (diesel engines)
If the warning lamp is lit up, there is a fault in the engine management
system. The engine control unit allows driving to continue in an emergency
program.
Seek professional help.
Particulate filter (diesel engines)
The particulate filter eliminates soot from emissions. The particles accumu-
late in the filter where they are normally burned off.
If the warning lamp is lit up, the filter is obstructed by soot.
In order for the filter to clean itself (if the traffic 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
1800-2500 1/min.
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 continue in an emergency program.
When switching the ignition off and on again, the warning lamp also
lights up.
Seek professional help.
WARNING
● The particulate filter attains very high temperatures. 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!
● Always adjust your speed to suit the weather, road, terrain and traffic
conditions. Never be encouraged, by the recommendations shown in the
warning lamps, to fail to respect traffic legislation.
CAUTION
While the warning lamp is lit up, the fuel consumption is high, and in
certain conditions, 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 provides informa-
tion about the countries where fuel with a high sulphur content is used.
Fuel reserve
The warning lamp lights up when approximately only 7 litres of fuel re-
main in the tank.

172Checking and refilling levels
–Press the tank flap with your hand to close it.
– Check that the fuel flap is correctly closed.
CAUTION
● Switch off the auxiliary heater (heater and independent heater) before
filling the tank.
● The fuel tank is full as soon as the automatic filler nozzle cuts out. Do
not continue filling, 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 pet-
rol with 95 and 91 octane rating (RON) or DIN 51626 – 2, or E5 for unleaded
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, although this will result in a slight loss of power.
If, as an emergency measure, you have to fill the tank with petrol with a low-
er RON to that prescribed, use only moderate engine speeds and light throt-
tle. High engine speed and full throttle can seriously damage the engine!
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 unleaded petrol with
95 RON is not available, you can fill up with petrol
with 91 RON as an emergency measure. In this case, use only moderate en-
gine speeds and a light throttle. High engine speed and full throttle can se-
riously 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 as an emergency meas-
ure. Risk of seriously 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, although this will result in a slight loss of power.
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 moder-
ate engine speeds and a light throttle. High engine speed and full throttle
can seriously 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 as an emergency meas-
ure. Risk of seriously damaging the engine!
Fuel additives
Unleaded petrol complying with the EN 228 Standard (in Germany, also DIN
51626-1, or E10 for unleaded petrol with 95 RON and 91 RON or DIN 51626
– 2, or E5 for unleaded petrol with 95 and 98 RON) meets all of the

Wheels and tyres
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 driving style, driving on loose
surfaces or in the winter) the warning lamp may take a while to light
up or may remain switched off.
● Despite the tyre pressure monitoring system, the driver remains re-
sponsible for maintaining 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 pres-
sure.
● The tyre pressure monitoring system is unable to warn of a sudden drop
in tyre pressure, 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 system works correctly, the basic
setting must be performed every 10 000 km (6000 miles) or once a year.
Wheel bolts
The wheel bolts are matched to the rims. When installing different wheels,
e.g. to fit light alloy wheels or wheels with winter tyres, it is important to use
the correct wheel bolts with the right length and correctly shaped bolt
heads. The is essential for the secure fit of the wheels and for the proper
function of the brake system. Winter tyres
Winter tyres will significantly improve handling 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 speed tyres (code letters H or V on the sidewall).
In order to preserve the performance of the vehicle as much as possible,
winter tyres must be fitted on all four wheels, the minimum 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 rating 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 down as quickly. They also reduce fuel consumption.
Snow chains
Snow chains must only be used on the front wheels.
In winter road conditions, snow chains not only help to improve grip but al-
so improve the braking capacity.
For technical reasons snow chains may only be used on tyres with the fol-
lowing wheel rim/tyre combinations.
