The vehicle's handlin gcharacteristics may be
affected. Adjust your drivin gstyle and speed
accordingly.
Immediately consult aqualified specialist
workshop which has the necessary specialist
knowledge and tools to carr yout the work
required. Mercedes-Ben zrecommends that
you use aMercedes-Ben zService Centre for
this purpose .Inparticular, work relevant to
safet yoro nsafety-related systems must be
carried out at aqualified specialist workshop. Coolant temperatur
egauge
The coolan ttemperature gauge is in the
instrumen tcluster on the right-han dside.
Under normal operating condition sand with
the specified coolan tlevel, the coolan ttem-
perature may rise to 120 †. The coolan ttem-
perature may rise to the top end of the scale
at high outside temperatures and on long
uphill stretches. Speedometer with segments
The segment sinthe speedometer indicate
which speed rang eisavailable.
Cruise control mode:
The segment slight up fro mthe stored speed
to the maximum speed.
Variable Speedtronic mode:
The segment slight up fro mthe star tofthe
scale to the selected limit speed.
Distronic Plus* mode:
One or two segment saround the stored
speed light up. Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engin ewhen the
red band is reached. !
Do not drive in the overrevving range.
Doin gsow ill damage the engine. Outside temperatur

Risk of accident
At temperatures just above freezin gpoint ,the
street may be icy, especially in wooded areas
or on bridges .Ifyou do not adapt your driving
style to the conditions, the vehicle could skid.
For this reason ,adapt your drivin gstyle and
speed to the weathe rconditions.
Changes in the outside temperature are dis-
played after ashor tdelay. On-board computer
Points to remember
The on-board computer is activate dassoon
as you turn the key to position 1in the ignition
lock. G
Risk of accident
Only use the on-board computer when road
and traffic condition spermit. You would oth-
erwise be distracted and unable to concen-
trate properly on driving, and could cause an
accident. Multifunction steering wheel
You can control the multi-function display and
the settings in the on-board computer using On-board computer

For further information on engine oil, see
(Y page 288). Coolant
Only chec kthe coolan tlevel when the vehicle
is on alevel surface and the engine has cooled
down.
X Turn the key to position 2(Y page 65) in
the ignition lock.
X Check the coolan ttemperature gauge in
the instrumen tcluster. G
Risk of injury
The cooling system is pressurised. Therefore,
only unscrew the cap onc ethe engine has
coole ddown. The coolan ttemperature gauge
must display less than 70 †. Otherwise, you
could be scalde difhot coolan tescapes.
The coolan texpansion tan kislocated in the
engine compartmen tonthe right when
viewed in the direction of travel. X
Slowly tur ncap 0046 half aturna nti-clock-

The red coolant
warning lamp
comes on while
the engine is
running. Awarn-
ing tone also
sounds. The coolant temperature has exceeded 130 †. The airflow to the
radiator may be blocked or the coolant level may be too low.
The engine is not being cooled sufficiently and may be damaged.
X
Pull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
X Allow the engine and coolant to cool.
X Make sure that the air supply to the radiator is not blocked, e.g.
by slush.
X Check the coolant level (Y page 183). Observe the warning
notes.
X If necessary, top up the coolant.
X Have the engine cooling system checked at aqualified specialist
workshop if the coolant needs topping up more often than usual.
If the coolant level is correct,t he electric radiator fan may be
faulty.
X Do not continue driving under any circumstances.
X Consult aqualified specialist workshop. 00BB

0050Solutions Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or amechanical
componentoft he engine control unit.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture gauge shows a
value above 120 †.
The coolant warning
lamp may also light up
and awarning tone may
sound (Y page 107). 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 183). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct,t
he radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X If the coolant temperature is less than 120 †, you can continue
driving to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving on
mountain roads and stop/start driving. 242
