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.

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 starter switch 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
engine to the drive axle. When the
brakes are released, the vehicle
can be moved freely (pushed or
towed).
To avoid damage to the transmis-
sion, never engageN while driving.
If 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 automati-
cally. All five forward gears are
available.
!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 51).
When parked on an incline, turn the front
wheels towards the road curb.

Select
Wfor winter 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 starter switch, take it with you
and lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Children could move
the selector lever 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.

Accelerator position
Your driving style influences the transmis-
sion’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshiftingKickdown
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 second gear and reverse gear
can be activated.
Stop the vehicle.

Move selector lever toP.

Turn off the engine.

Wait at least ten seconds before
restarting.

Restart the engine.

Move selector lever to positionD (for
second gear) orR.

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

set speed will be resumed.
!Vehicles with automatic transmission:
Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iVehicles with manual transmission:

set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to preset
speed can cause an accident and/or serious
personal 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.

225 Operation
Driving instructions
After hard braking, it is advisable to drive
on for some time, rather than immediately
parking, so that the air stream will cool
down the brakes faster.
Driving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the oper-
ating temperature has been reached.
When starting off on a slippery surface, do
not allow one drive wheel to spin for an ex-
tended period with the ESP switched off.
Doing so may cause serious damage to the
drive train which is not covered by the
Mercedes-Benz Limited Warranty.
Parking
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
can result in an accident.!When driving down long and steep
grades, relieve the load on the brakes
by shifting into a lower gear to use the
engine’s braking power. This helps pre-
vent overheating of the brakes and re-
duces brake pad wear.
!Simultaneously depressing the
accelerator pedal and applying the
brake reduces engine performance and
causes premature brake and drivetrain
wear.
!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move selector lever to positionP (man-
ual transmission: first or reverse gear).
In addition, when parking on hills,
always turn front wheels towards road
curb.

226 OperationDriving instructions
Tires
Tread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1/16
in (1.5 mm), at which point
the tire is considered worn and should be
replaced.The tread wear indicator appears as a solid
band across the tread.
Specified tire pressures must be main-
tained. This applies particularly if the tires
are subject to high loads (e.g. high speeds,
heavy loads, high ambient temperatures).
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Move the selector lever to positionP
(manual transmission: first or reverse
gear).


Slowly release brake pedal.


When parked on an incline, turn front
wheels towards the road curb.


Turn the key to starter switch
position0.


Take the key and lock vehicle when leav-
ing.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
ti o n t o an a re a wh ic h i s a s a fe dis ta n c e f ro m
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Center or tire dealer for re-
pairs.
Warning!
G
Do not allow your tires to wear down too far.
As tread depth approaches
1/16
in
(1.5 mm), the adhesion properties on a wet
road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
