Problem Possible causes/consequences and
M Solutions
Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at aqualified specialist
workshop. 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 299). 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
If the coolant temperature is below 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 in
mountainous terrain and stop-start traffic. Automatic transmission

WARNING
If the engine speed is above the idling speed
and you engage transmission position Dor
R,t he vehicle could pull away suddenly. There
is ar isk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do
not simultaneously accelerate. Selector lever

A Fuel gauge Coolant temperature gauge
The coolant temperature gauge is in the
instrument cluster on the left-hand side
(Y page 30).
Under normal operatin gconditions and with
the specified coolant level, 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
! Do not drive in the overrevving range.
Doin gsow ill damage the engine.
The red band in the rev counter indicates the
engine's overrevving range.
The fuel supply is interrupted to protec tthe
engine when the red band is reached. Outside temperature display

WARNING
At temperatures just above freezing point, the
street may be icy, especially in wooded areas
or on bridges. If you do not adapt your driving
style to the conditions, the vehicle could skid.
For this reason, adapt your driving style and
speed to the weather conditions.
The outside temperature displayisint he mul-
tifunction display( Ypage 211).
Changes in the outside temperature are dis-
played after ashort delay. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
R Cruise control activated (Y page 165):The segments light up from the stored
speed to the maximum speed.
R VariableS PEEDTRONIC activated
(Y page 168):
The segments light up from the start of the
scale to the selected limit speed.

One or two segments in the set speed
range light up.

Owner's Manual The coolant level is too low.
!
Avoid making long journeys with too little coolant in the engine
cooling system. The engine will otherwise be damaged.
X Top up the coolant, observing the warning notes before doing
so (Y page 299).
X If the coolant needs topping up more often than usual, have the
engine coolant system checked at aqualified specialist work-
shop. ? The fan motor is faulty.
X
If the coolant temperature is below 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 in
