cluster displayPractical hints Car care Index Important!
If the electronic key is left in the starter switch
position 0 for an extended period of time, it can no
longer be turned in the lock. In this case, remove
electronic key from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
starter switch. Do not leave the electronic key in starter
switch position 0.Notes:
A warning sounds when the driver’s door is opened
with the electronic key in starter switch position 1 or 0.
If the electronic key cannot be turned in the starter
switch, the vehicle battery may not be sufficiently
charged. See battery on page 357 or jump starting on
page 359.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.

•Do not forget, the engine can be started by anyone if
a KEYLESS-GO-card is left inside the vehicle.
•To be able to operate the vehicle in the case of a
malfunction in the KEYLESS-GO-system (e.g. strong
radio frequency disturbance), we recommend that
you carry the electronic key plus mechanical key
with you and keep them in a safe place so that they
are always handy. Never leave the electronic key in
the vehicle.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).Notes:
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.

* C = Category, see page 309
This message indicates a malfunction which must be
repaired immediately.
It 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 this message
displayed.
Doing so could result in serious engine damage that is
not covered by the Mercedes-Benz Limited Warranty.
