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

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
