Transmission positions
The current transmission position appears
in the instrument cluster.
1Current transmission position
!If the current transmission position does not
appear in the instrument cluster due to a
malfunction, for example, make sure that the
automatic transmission is in the desired position
by carefully driving off with the transmission in
drive positionD and program modeS
(
page 399) selected. Do not limit the gear
range.
Effect
ìPark 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 engage the elec-
tronic parking brake in addition
to shifting 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
or
open a door
the transmission will shift to park positionP
automatically.
Keep in mind that turning off the engine with the
SmartKey alone only will automatically shift the
transmission to neutral positionN.
!KEYLESS-GO*:
If you turn off the engine using the KEYLESS-GO
start/stop button and open the driver’s or pas-
senger door, the transmission will shift to park
positionP automatically.
Keep in mind that turning off the engine using
the KEYLESS-GO start/stop button alone only
will automatically shift the transmission to
neutral positionN.

Automatic transmission
If you want the gear position to remain in
neutral positionN, e.g. when taking the
vehicle through an automatic conveyor
type car wash or when towing the vehicle,
observe the following instructions.
!DISTRONIC Plus*:
The transmission will shift to park positionP
automatically, 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
electronic parking brake will be engaged auto-
matically.
iMake it a practice to always shift into park
positionP before turning off the engine and
remove the SmartKey from the starter
switch
or
open a door
or when using KEYLESS-GO*, before turning off
the engine with the start/stop button and open-
ing the driver’s or passenger door.
Effect
íReverse gear
Shift into reverse gearR only
when the vehicle is stopped.
ëNeutral
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 trans-
mission, never shift 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.
!If you turn off the engine using the
SmartKey or the KEYLESS-GO* start/stop
button, the transmission will shift to neutral
positionN automatically.
Warning!G
When leaving the SmartKey or SmartKey
with KEYLESS-GO* in the starter switch, do
not leave children unattended in the vehicle.
It is possible for children to switch on the
ignition which could result in unsupervised
use of vehicle equipment. Unsupervised use
of vehicle equipment could result in an
accident and/or serious personal injury.

Driving tips
Accelerator position
Your driving style influences the
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
transmission shifts into a lower gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:
Leave the 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:
Engage the electronic parking brake.
Shift into park positionP.
Maneuvering

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. approximately 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.
Working on the vehicleHill start assist system
On uphill grades with a gradient angle of
more than 5°, the hill start assist system
maintains the pressure in the brake sys-
tem for approximately 1 second after you
have released the brake pedal. Therefore,
you can start off smoothly without the
vehicle moving immediately after releasing
the brake pedal.The hill start assist system is inactive
when starting off on a level road or
downhill grades
with the transmission in neutral
position N
with the electronic parking brake en-
gaged
if the ESP® has switched off due to a
malfunction
Warning!G
When working on the vehicle, engage the
electronic parking brake and shift to park
positionP. Otherwise the vehicle could roll
away.
Warning!G
The hill start assist system is not designed
to function as a electronic parking brake and
does not prevent the vehicle from moving

Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control (page 405) and
DISTRONIC Plus*(
page 411), with
which the vehicle can maintain a preset
speed.
ABC (page 429) adjusts the vehicle
suspension characteristics automati-
cally and control the vehicle level.
Parktronic* (page 431) and
Park Assist* (
page 435), which serve
as a parking assistant.
Dynamic Rear View Monitor*
(
page 439) is an electronic and
visual parking aid.
Night View Assist* (page 446) illumi-
nates the road with infrared light in
addition to the normal headlamps.
For information on the ABS, Adaptive
Brake, BAS, BAS Plus*, EBP, ESP
® and
PRE-SAFE® Brake*, see “Driving safety
systems” (
page 64).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time.
You can set or resume the cruise control at
any speed over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
Warning!G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it
advisable to travel at a constant speed.
The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a constant speed.
The use of the cruise control can be dan-
gerous on slippery roads. Rapid changes
in tire traction can result in wheel spin
and loss of control.
Deactivate the cruise control when
driving in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

The cruise control brakes automatically so
that the set speed is not exceeded. The
brake pedal depresses when the cruise con-
trol engages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
– your foot could become caught.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
