(120°C). The coolant temperature may
climb to the red marking:

at high outside temperatures

within the red marking.
Warning!
G
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down.
iAvoid driving at excessive engine
speeds, as it may result in serious en-
gine damage that is not covered by the
Mercedes-Benz Limited Warranty.

90 Controls in detailInstrument clusterOutside temperature indicator
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.
Setting clock
Hours
Pull out the right knob5 in the instru-
ment cluster (

counterclockwise.
Minutes

Pull out the right knob5 in the instru-
ment cluster and turn it clockwise.
Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
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.
iTo adjust the time by a single hour or a
few minutes, turn knob5 just a few de-
grees in the direction indicated for
hours or minutes.

Information for driving with a manual
transmission is found in the “Getting start-
ed” section (
page 40).
Gearshift leverDo not exceed the maximum speed in the
individual gears. Refer to tachometer
(page 89) for engine speeds.
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or re-
verse gear and parking brake engaged is
dangerous. Also, when parked on an incline,
an engaged first or reverse gear alone may
not prevent your vehicle from moving, possi-
bly hitting people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 47).
When parked on an incline, turn front wheels
towards the road curb.
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Children could move the gearshift
lever, which could result in an accident
and/or serious injury.iNever hold the vehicle stopped on a hill
by using the clutch pedal. The clutch
may be damaged which is not covered
by the Mercedes-Benz Limited
Warranty.

96 Controls in detailAutomatic transmission*Gear 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 steering lock 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 47).
When parked on an incline, turn front wheels
towards the road curb.
