Immobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
Activating

With the key: Removing the key from
the starter switch activates the immo-
bilizer.


With KEYLESS-GO*: Turning off the en-
gine by means of the KEYLESS-GO
start/stop button on the gear selector
lever activates the immobilizer.Deactivating


With the key: Inserting the key in the
starter switch deactivates the immobi-
lizer.


With KEYLESS-GO*: Starting the en-
gine by means of the KEYLESS-GO
start/stop button on the gear selector
lever deactivates the immobilizer.
iIn case the engine cannot be started
(yet the vehicle’s battery is charged),
the system is not operational. Contact
an authorized Mercedes-Benz Center
or call 1-800-FOR-MERCedes (in the
USA), or 1-800-387-0100 (in Canada).

113 Controls in detail
Instrument cluster
Tachometer
The red marking on the tachometer de-
notes excessive engine speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. This
means that the accuracy of the displayed
temperature can only be verified by com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs etc.).When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.
!Avoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
The outside temperature indicator is not de-
s i g n e d t o s e r v e a s a n i c e - w a r n i n g d e v i c e a n d
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

ment to be increased at four different
levels.

rear passenger compartment2 and3
is the same as at the dashboard center
air vents.
