Problem Possible causes/consequences and
M Solutions
Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop, e.g. a Mercedes-Benz Service Centre.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture display is showing
more than 120 †. The
coolant warning lamp
may also be lit and a
warning tone may
sound. The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X Check the coolant level (Y page 303). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.
X
At coolant temperatures under 120 †, drive on to the nearest
qualified specialist workshop, e.g. to a Mercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. Manual transmission
Gear lever
Gear lever
!
Only engage gear when the clutch pedal
is depressed.
! When shifting between 5thand 6thgear,
you should always push the gear lever all the way to the right. Otherwise, you could
shift unintentionally into
3rdor4th gear
and damage the transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise a risk of damaging the
clutch.
! On long and steep downhill gradients,
especially if the vehicle is laden or towing
a trailer, you must shift into gear 1, 2or3
in good time. This uses the engine's braking
effect.T his relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. 144

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 26).Important safety notes
You will find an illustration of the instrument
cluster in the "At a glance" section
(Y page 32). G
WARNING
Only use the on-board computer when road
and traffic conditions permit .You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. G
WARNING
If the instrument cluster or multifunction dis-
play fails, no messages can be displayed.
This means that you will not see information
about the driving situation, such as the speed,
outside temperature, warning/indicator
lamps, display messages or system failures.
Handling characteristics may be affected.
Adapt your driving style and speed accord-
ingly.
Immediately consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop. G
WARNING
The on-board computer only records and dis-
plays malfunctions and warnings from certain
systems. For this reason, you should always
make sure that your vehicle is safe to use. You
could otherwise cause an accident by driving
an unsafe vehicle. G
WARNING
The operating safety of your vehicle could be
jeopardised if maintenance work is carried
out incorrectly. As aresult, you could lose
control of the vehicle and cause an accident.
In addition, the safety systems may no longer
be able to protec tyou or others as they are
designed to do.
Always have maintenance work carried out at
a qualified specialist workshop. The qualified
specialist workshop must have the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. Displays and operation (4-button mul-
tifunction steering wheel)
Coolant temperature gauge
The coolant temperature gauge is in the
instrument cluster on the left-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †.
The coolant temperature may rise to the top
end of the scale at high outside temperatures
and on long uphill stretches. Rev counter
The red band in the rev counter indicates the
engine's overrevving range. 206

X To reset the trip computer: press and
hold the Cbutton on the steering wheel
until the values have been reset. Calling up the range
X Press the Vbutton on the steering
wheel repeatedly until the approximate
range appears.
The approximate range which can be covered
depends on the fuel level and your current
driving style .Ifthere is only a small amount
of fuel left in the fuel tank, the display shows
a vehicle being refuelled Cinstead of the
range. Switching the daytime driving lights
on/off
If you have activated the Day. driv.lights: function and the light switch is in the Ã
position, the daytime driving lights are
automatically switched on during daylight
hours when the engine is running. When it is
dark, the side lamps and the dipped-beam
headlamps are switched on automatically.
On vehicles with daytime driving lamps, the
factory setting is on .
If you want to change the setting for the Day. driv. lights: function, you have to turn
the key in the ignition lock to position 1.
X Press the Vbutton on the steering
wheel repeatedly until the Day. driv. lights: menu appears.
You will see the selected setting: on or
off .
X Press the WorX button to change
the setting. Displays and operation (12-button
multifunction steering wheel)
Coolant temperature gauge
The coolant temperature gauge is in the
instrumentc luster on the left-hand side.
Under normal operating conditions and with
the specified coolan tlevel, the coolant tem-
perature may rise to 120 †.
At high outside temperatures and when driv-
ing uphill, the coolant temperature may rise
to the end of the scale. Rev counter
The red band in the rev counter indicates the
engine's overrevving range.
! Do not drive in the overrevving range.
Doing so will damage the engine.
The fuel supply is interrupted to protec tthe
engine when the red band is reached. 210
