speed.
To help protect the engine, the fuel supply
is interrupted if the engine is operated
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 (
page 20) and turn it
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.

Warning!
G
On slippery road surfaces as well as high en-
gine speeds, never downshift in order to ob-
tain braking action. This could result in drive
wheel slip and reduced vehicle control. Your
vehicle’s ABS will not prevent this type of
loss of control.!Downshifting gears leading to overrev-
ving the engine can result in engine
damage that is not covered by the
Mercedes-Benz Limited Warranty.
Do not exceed the engine speed limits
(page 89).

Automatic transmission*
Automatic transmission*
Information for driving with an automatic
transmission is found in the “Getting start-
ed” section (
page 41).
Your transmission adapts its gear shifting
process to your individual driving style by
continually adjusting the shift points up or
down. These shift point adjustments are
performed based on current operating and
driving conditions.
If the operating conditions change, the au-
tomatic transmission reacts by adjusting
its gear shift program.
The automatic transmission selects indi-
vidual gears automatically, dependent
upon


the selector lever positionD with gear
ranges4, 3, 2, 1 (
page 95)


the selected shift program (W/S)
(page 97)


the position of the accelerator pedal
(page 98)


the vehicle speed
1Gear range indicator display
The current selector lever position appears
in gear range indicator display1.When the selector lever is in positionD,
you can influence transmission shifting by


limiting the gear range


changing gears yourself
iDuring the brief warm-up, the transmis-
sion upshifting is delayed. This allows
the catalytic converter to heat up more
quickly to operating temperatures.
Warning!
G
It is dangerous to shift the selector lever out
ofP orN if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the en-
gine is idling normally and when your right
foot is firmly on the brake pedal.

94 Controls in detailAutomatic transmission*One-touch gearshifting
Even with an automatic transmission you
can change the gears yourself when the
selector lever is in positionD.
Downshifting
Briefly press the selector lever to the
left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action si-
multaneously limits the gear range of the
transmission (
page 95).Upshifting

Briefly press the selector lever to the
right in the D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simulta-
neously extends the gear range of the
transmission.Canceling gear range limit

Press and hold the selector lever in the
D+direction until Dreappears in the
tachometer display field.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range

Press and hold the gear selector lever
in the D–direction.
The transmission will automatically select
the gear range suited for optimal accelera-
tion and deceleration. This will involve
shifting down one or more gears.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
iTo avoid overrevving the engine when
the selector lever is moved to the
D–direction, the transmission will not
shift to a lower gear if the engine's
max. speed limit would be exceeded.

verse the gear range limit by pressing the
lever to the right (D+).
The selected gear range will appear in the
gear range indicator display (
page 93). If
you press on the accelerator when the en-
gine has reached its rpm limit, the trans-
mission will upshift beyond any gear range
limit selected.
