(page 373)
the vehicle speed
With drive positionD selected, you can use
the steering wheel gearshift control
buttons (
page 375) to influence auto-
matic transmission shifting by:
limiting the gear range
changing gears manually
!
Shift the automatic transmission directly
from drive positionD to reverse gearR, from
reverse gearR to drive positionD or directly to
park positionP only when the vehicle is stopped.
Otherwise the automatic transmission could be
damaged.
When trying to free a vehicle stuck in mud or
snow, see “Rocking the vehicle” (
page 373).
i
When the vehicle needs to be moved with
the engine switched off and the automatic trans-
mission set to neutral positionN (
page 371),
e.g. in an automatic car wash, do not press the
handle for electric parking brake.
!
Allow engine to warm up under low load use.
Do not place full load on the engine until the op-
erating temperature has been reached.
Shift into reverse gearR or parking positionP
only when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road surfac-
es. This may cause serious damage to the driv-
etrain which is not covered by the
Mercedes-Benz Limited Warranty.

1Current automatic transmission posi-
tion!
If the automatic transmission position fails
in the tachometer display, you should check
whether the gear selector lever is placed in the
desired position while driving off with added cau-
tion. We recommend you to shift the gear selec-
tor lever to positionD. Do not limit the gear
range.
Effect
ì
Park position
Shift into park positionP only
when vehicle is stopped. The
park position is not intended to
serve as a brake when the vehi-
cle is parked. Rather, the driver
should always set the electric
parking brake in addition to shift-
ing into park positionP to secure
the vehicle.
If the vehicle’s electrical system
is malfunctioning, the automatic
transmission could remain
locked in park positionP.
Have the vehicle checked as
soon as possible by an autho-
rized Mercedes-Benz Center.
!
SmartKey:
If you turn off the engine using the SmartKey and
remove the SmartKey from the starter switch,
the automatic transmission will shift to park
positionP automatically. Keep in mind that turn-
ing off the engine with the SmartKey alone will
not automatically shift the automatic transmis-
sion to park positionP. Only when the SmartKey
is removed from the starter switch, will the auto-
matic transmission automatically shift to park
positionP.
KEYLESS-GO*:
If you turn off the engine using the KEYLESS-GO
start/stop button and open the driver’s door, the
automatic transmission will shift to park
positionP automatically. Keep in mind that turn-
ing off the engine using the KEYLESS-GO
start/stop button alone will not automatically
shift the automatic transmission to park
positionP. Only when the driver’s door is
opened, will the automatic transmission auto-
matically shift to park positionP.
DISTRONIC Plus*:
the transmission will shift to park positionP au-
tomatically, only when DISTRONIC Plus brings
your vehicle to a standstill, and when it meets at
least one of the following conditions at the same
time:
the engine is turned off
the driver’s or passenger door opens and the
seat belt is not engaged in the buckle
In addition to shifting to park positionP, the elec-
tric parking brake will be engaged automatically.

Automatic transmission
Even though this is possible, make it a practice
to always shift into park positionP before turning
off the engine and remove the SmartKey from
the starter switch, or when using KEYLESS-GO*,
before turning off the engine with the start/stop
button and opening the driver’s door.!
If you want the gear position to remain in
neutral positionN (for example when the vehicle
is pulled through a car wash)
do not remove the SmartKey from the starter
switch
or, when using KEYLESS-GO*
do not turn off the engine using the
KEYLESS-GO start/stop button* and open
the driver’s door
Otherwise, the automatic transmission will shift
to park positionP and lock the wheels, prevent-
ing the vehicle from being pulled through a car
wash.
Effect
í
Reverse gear
Shift into reverse gearR only
when the vehicle is stopped.
ë
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 automat-
ic transmission, avoid shifting
into neutral positionN while
driving.
If the ESP
® is deactivated or
malfunctioning:
Shift into neutral positionN only
if the vehicle is in danger of
skidding, e.g. on icy roads.
ê
Drive
The automatic transmission
shifts automatically. All forward
gears are available.
!
Coasting the vehicle, or driving for any other
reason in neutral positionN can result in auto-
matic transmission damage that is not covered
by the Mercedes-Benz Limited Warranty.
Warning!
G
Getting out of your vehicle without shifting
into park positionP is dangerous. Also, park
positionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects.
Always set the electric parking brake in
addition to shifting to park positionP
(page 364).
When parked on an incline, turn the front
wheels towards the road curb.
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.

Driving tips
Accelerator position
Your driving style influences the automatic
transmission’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.
Depending on the engine speed the au-
tomatic transmission shifts into a lower
gear.
Ease on the accelerator when you have
reached the desired speed.
The automatic transmission shifts up
again.Stopping
When you stop briefly, e.g. at traffic lights:
Leave the automatic transmission in
gear.
Hold the vehicle with the brake.
When you stop for a longer period of time
with the engine idling and/or on a hill:
Set the electric parking brake.
Shift into park positionP.
Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:
Control the vehicle speed by gradually
releasing the brakes.
Accelerate gently.
Never abruptly step on the accelerator.Rocking the vehicle
Rocking the vehicle by shifting between
drive positionD and reverse gearR can
help free a vehicle stuck in mud or snow.
The engine control system of this vehicle
electronically limits shifting between drive
positionD and reverse gearR to very low
speeds (i.e. approx. 5 mph (9 km/h)). To
shift between drive positionD and reverse
gearR, move the gear selector lever past
the resistance point up or down.

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
improved 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.
Program modeS:
Engine, automatic transmission and
suspension tuning are more perfor-
mance oriented.
The vehicle starts out in first gear.
Upshifts occur later.
Steering wheel gearshift control
With drive positionD selected, you can
limit or extend the gear range.
The steering wheel gearshift buttons are
located on the back of the steering wheel
