Parktronic Malfunction
All red segments of the warning
indicators light up, and a warning
sounds for 3 seconds, if Parktronic
does not function properly.
A dirty sensor could be the reason.
After cleaning the sensors, turn key in
steering lock to position 2. If the defect
continues to be displayed, have the
system checked at your authorized
Mercedes-Benz dealer.
Charge Indicator Lamp
Should the charge indicator lamp fail to
come on prior to starting when the key
is in steering lock position 2 or should
it fail to go out after starting or during
operation, this indicates a fault which
must be repaired at an authorized
Mercedes-Benz dealer immediately.
If the charge indicator lamp comes on
while the engine is running, this may
indicate that the poly-V-belt has
broken. Should this condition occur,
the poly-V-belt must be replaced
before continuing to operate the
vehicle. Otherwise, the engine will
overheat due to an inoperative water
pump which may result in damage to
the engine.
Do not continue to drive the vehicle
with the charge indicator lamp
illuminated. Doing so could result in
engine damage that is not covered by
the Mercedes-Benz Limited Warranty.
Engine Oil Pressure Gauge
The oil pressure at idle speed may drop
if the engine is at operating temperature.
This will not jeopardize the engine's
operational reliability.
Pressure must, however, rise
immediately upon acceleration.
Note:
If the oil pressure gauge needle drops
to "0" with the engine running, then
damage to the engine may occur with
continued operation. Turn off engine
immediately and contact an authorized
Mercedes-Benz dealer. Do not operate
the car until the condition is repaired.
