Coolant temperature gauge
Under normal driving conditions, the cool-
ant temperature may rise to 248°F
(120°C). The coolant temperature may
climb to the red marking:
at high outside temperatures
during stop-and-go city traffic
when driving on hilly terrain
The engine should not be operated with
the coolant temperature in the red zone.
Doing so may cause serious engine dam-
age which is not covered by the
Mercedes-Benz Limited Warranty.

Press the left knob1 in the instru-

The display changes between main
odometer and trip odometer.
Press the left knob1 twice.
The next scheduled service is displayed
(page 232).
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 the
engine has cooled down.

Tachometer
To help protect the engine, the fuel supply

above its specified limit.
Outside temperature indicator
The outside temperature is displayed in
the instrument cluster (
page 24).
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.

ment cluster (

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 set the clock by a single hour or a
few minutes, turn knob2 just a few
degrees in the direction indicated for
hours or minutes.

Automatic transmission
Automatic transmission
Information on driving with an automatic
transmission is found in the “Getting
started” section (
page 46).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its gear shift program.The automatic transmission selects indi-
vidual gears automatically, depending on:
the gear selector lever positionD with
gear ranges4, 3, 2, 1 (
page 121)
the position of the accelerator pedal
(page 123)
the vehicle speed
The current gear selector lever position
appears in the tachometer display
(
page 24).
When the gear selector lever is in
positionD, you can influence transmission
shifting by
limiting the gear range
changing gears manually
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
It is dangerous to shift the gear 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 engine is idling normally and when
your right foot is firmly on the brake pedal.

120 Controls in detailAutomatic transmissionOne-touch gearshifting
Even with an automatic transmission you
can change the gears manually when the
gear selector lever is in positionD.
Downshifting
Briefly press the gear selector lever to
the left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action
simultaneously limits the gear range of the
transmission (
page 121).Upshifting
Briefly press the gear 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 simul-
taneously extends the gear range of the
transmission.Canceling gear range limit
Press and hold the gear selector lever
in the D+direction until D reappears in
the tachometer display.
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
acceleration 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
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
iTo avoid overrevving the engine when
the gear selector lever is moved to
the D– direction, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.

Gear ranges
With the gear selector lever in positionD,
you can limit the transmission’s gear range
by pressing the gear selector lever to the
left (D-), and reverse the gear range limit
by pressing the gear selector lever to the
right (D+).
The selected gear range appears in the
tachometer display. If you press on the
accelerator when the engine has reached
its rpm limit, the transmission will upshift
beyond any gear range limit selected.
Effect
é
The transmission shifts through
fourth gear only.
è
The transmission shifts through
third gear only.
With this selection you can use
the braking effect of the engine.
Effect
ç
The transmission shifts through
second gear only.
Allows the use of engine’s
braking power when driving:
on steep downgrades
in mountainous regions
under extreme operating
conditions
æ
The transmission operates in
first gear only.
For maximum use of engine’s
braking effect on very steep or
lengthy downgrades.
