find detailed information on how to oper-
ate the equipment installed on your vehi-
cle. If you are already familiar with the
basic functions of your vehicle, this section
will be of particular interest to you.
To quickly familiarize yourself with the ba-
sic functions of the vehicle, refer to the
“Getting started” section of this manual.
The corresponding page numbers are giv-
en at the beginning of each segment.
Locking and unlockingKeys
Your vehicle comes supplied with two
SmartKeys with remote controls and a re-
movable mechanical key. The locking tabs
for the mechanical key portion of the two
keys are a different color to help distin-
guish each key unit.
The remote control key provides an ex-
tended operating range. To prevent theft,
however, it is advisable to only unlock the
vehicle when you are in close proximity to
it.
The key centrally locks and unlocks:

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!

The outside temperature indicator is not de-

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.

144 Controls in detailAutomatic transmissionGear selector lever position
Effect
P
Park position
Selector position when the vehicle
is parked. Only place selector lever
in positionP when vehicle is
stopped. The park position is not in-
tended to serve as a brake when
the vehicle is parked. Rather, the
driver should always set the park-
ing brake in addition to placing the
selector lever in positionP to se-
cure the vehicle.
The key can only be removed from
the starter switch with the selector
lever in positionP. With the key re-
moved the selector lever is locked
in positionP.
Effect
R
Reverse gear
Place selector lever in positionR only
when vehicle is stopped.
N
Neutral
No power is transmitted from the en-
gine to the drive axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
To avoid damage to the transmission,
never engageN while driving.
If the ESP is deactivated or malfunc-
tioning:
Only move selector lever toN if the
vehicle is in danger of skidding (e.g.
on icy roads).
D
Drive
The transmission shifts automatical-
ly. All five forward gears are avail-
able.
!Coasting the vehicle, or driving for any
other reason with selector lever inN
can result in transmission damage that
is not covered by the Mercedes-Benz
Limited Warranty.Warning!
G
Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, positionP alone is not intend-
ed to or capable of preventing your vehicle
from moving, possibly hitting people or ob-
jects.
Always set the parking brake in addition to
shifting to positionP (
page 45).
When parked on an incline, turn the front
wheels towards the road curb.
