Instrument clusterA full view illustration of the instrument
cluster can be found in the “At a glance”
section of this manual (
page 20).
The instrument cluster is activated when
you:
open a door
turn on the ignition
press the reset knob (
page 20)
switch on the exterior lamps
Only opening a door will activate the in-
strument cluster for approximately
30 seconds.
You can change the instrument cluster set-
tings in the Instrument cluster submenu of
the control system (
page 122).
Instrument cluster illumination
Use the reset knob to adjust the illumina-
tion brightness for the instrument cluster
and the switches on the center console.
To brighten illumination
Turn the reset knob in the instrument
cluster (
page 20) clockwise.
The instrument cluster illumination will
brighten.To dim illumination
Turn the reset knob in the instrument
cluster (
page 20) counterclockwise.
The instrument cluster illumination will
dim.
Coolant temperature gauge
Under normal driving conditions, the cool-
ant temperature may rise to 248°F
(120°C). The coolant temperature may
rise to 266°F (130°C) at high outside tem-
peratures or when driving in hilly terrain.
The engine should not be operated with
the coolant temperature above 266°F
(130°C). Doing so may cause serious en-
gine damage which is not covered by the
Mercedes-Benz Limited Warranty.
iThe instrument cluster illumination is
dimmed or brightened to suit ambient
light conditions.

odometer display (

played.
Press and hold reset knob4

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.

To help protect the engine, the fuel supply
is interrupted if the engine is operated at
an excessive speed.
Outside 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.
!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-
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.

from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.

Automatic transmission
Automatic transmission
Information for driving with an automatic
transmission is found in the “Getting start-
ed” section (
page 39).
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 139)
the selected shift program
(S/W)(
page 141)
the position of the accelerator pedal
(page 142)
the vehicle speed
The current selector lever position and
shift program (S/W) appear in the
tachometer display (
page 110).When the selector lever is in positionD,
you can influence transmission shifting by
limiting the gear range
changing gears yourselfWarning!
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.

138 Controls in detailAutomatic transmissionOne-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 cur-
rent gear to the next lower gear. This
action simultaneously limits the gear
range of the transmission
(page 139).Upshifting
Briefly press the selector lever to the
right in the D+direction.
The transmission will shift from the cur-
r e n t g e a r t o t h e ne x t h i g h e r g e a r a s p e r -
mitted by the shift program. This action
simultaneously extends the gear range
of the transmission.Canceling gear range limit
Press and hold the selector lever in the
D+direction until D reappears in the
tachometer display field.
The transmission will shift from the cur-
rent 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 se-
lect 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 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– di-
rection, the transmission will not shift
to a lower gear if the engine’s revolu-
tions per minute limit would be exceed-
ed.

Gear ranges
With the selector lever in positionD, you
can limit the transmission’s gear range by
pressing the lever to the left (D-), and re-
verse the gear range limit by pressing the
lever to the right (D+).
The selected gear range will appear in the
tachometer display field. If you press on
the accelerator when the engine has
reached its rpm limit, the transmission will
upshift beyond any gear range limit
selected.
