Vehicles with automatic transmission
When the engine is running and the
selector lever is in driving position, the low
beam headlamps are automatically
switched on.
When you shift from a driving position to
positionN orP, the low beam switches off
(2 seconds delay).
Vehicles with manual transmission
With the engine running, the low beam
headlamps are automatically switched on.
iIf you remove the key and open the
driver’s door while the parking lamps or
low beam headlamps are switched on,
then a warning sounds.
iWith the daytime running lamp mode
activated and the engine running, the
low beam headlamps cannot be
switched off manually.

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.

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
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.

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.

Wfor comfortable driving:


The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.


Traction and driving stability are im-
proved on icy roads.


Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.


The power transmission ratio for se-
lector lever positionR changes de-
pending on the program mode
selected (
W or
S).
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 selector le-
ver from positionP, which could result in an
accident and/or serious injury.
!Never change the program mode when
the selector lever is out of positionP. It
could result in a change of driving char-
acteristics for which you may not be
prepared.

Your driving style influences the transmis-
sion’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
The transmission shifts into a lower
gear.

Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Emergency operation (Limp Home
Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode only 2nd gear and reverse gear can
be activated.
Stop the vehicle.

Move selector lever toP.

Turn off the engine.

Wait at least 10 seconds before re-
starting.

Restart the engine.

Move selector lever to positionD (for
2nd gear) orR.

Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.

Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed could cause an accident and/or seri-
ous injury to you and others.
iDepressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.
iVehicles with automatic transmission:
When you use the cruise control lever
to decelerate, the transmission will au-
tomatically downshift if the engine’s
braking power does not brake the vehi-
cle sufficiently.
Vehicles with manual transmission:
The set cruise controlled speed is
switched off when declutching exceeds
4 seconds during downshifting a gear.
