Automatic transmission
Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 98).
GWarning!
Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between or
under the pedals. You could then no longer
brake or accelerate. This could lead to
accidents and injury.
! Allow the engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature has
been reached.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces.
This may cause serious damage to the
engine and the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more quickly
to operating temperature.

It is dangerous to shift the automatic
transmission out of park position P or neutral
position N 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 in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.

EffectBPark position
Shift the automatic transmission
into park position P only when the
vehicle is stopped. The park
position is not intended to serve as
a brake when the vehicle is parked.
Rather, the driver should always
engage the parking brake in
addition to shifting the automatic
transmission into park position P to
secure the vehicle.
The SmartKey can only be removed
from the starter switch with the
gear selector lever in park position
P . With the SmartKey removed from
the starter switch, the gear selector
lever is locked in park position P.
If the vehicle’s electrical system is
malfunctioning, the gear selector
lever could remain locked in park
position P.XHave the vehicle’s electrical
system checked at an authorized
Mercedes-Benz Center as soon
as possible.CReverse gear
Shift the automatic transmission
into reverse gear R only when the
vehicle is stopped.EffectANeutral position
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
transmission, never shift the
automatic transmission into neutral
position N while driving.
Exception: If the ESP ®
is switched
off or malfunctioning, shift the
automatic transmission into neutral
position N if the vehicle is in danger
of skidding.
! Coasting the vehicle, or driving
for any other reason with the
automatic transmission in
neutral position N can result in
transmission damage that is not
covered by the Mercedes-Benz

automatically. All forward gears are
available.
Driving tips
Kickdown
Use the kickdown when you want maximum
acceleration.
XU.S. vehicles except AMG vehicles:
Fully depress the accelerator pedal.
Depending on the engine speed the
automatic transmission shifts into a lower
gear.XCanada vehicles and AMG vehicles:
Depress the accelerator pedal past the
point of resistance.

Working on the vehicleGWarning!
When working on the vehicle, engage the
parking brake and shift the automatic
transmission into park position P. Otherwise
the vehicle could roll away which could result
in an accident and/or serious personal injury.

GWarning!
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.
RThe use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
RThe use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
RDeactivate the cruise control when driving
in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.
GWarning!
The cruise control brakes automatically so
that the set speed is not exceeded.

adjustments.
Increase or decrease the set vehicle speed to
a value that the prevailing road conditions and
legal speed limits permit. Otherwise, sudden
and unexpected acceleration or deceleration
of the vehicle could cause an accident and/
or serious injury to you and others.
When you use the cruise control lever to
decelerate, the brake system will brake the
vehicle automatically if the engine’s braking
power does not brake the vehicle sufficiently.

Distronic switches off and releases the brakes
when the vehicle decelerates below the
minimum speed of 20 mph (30 km/h) by
operation of the system. At that time the
driver must apply the brakes in order to
reduce vehicle speed further or bring it to a
stop.

deactivate the Distronic. After a brief
acceleration (e.g. for passing), the Distronic
will resume the last set speed.
Setting the following distance in
Distronic
You can set the specified following distance
for Distronic by varying the time setting
between 1.0 and 2.0 seconds. Using this time
setting and the current speed of your vehicle,
Distronic calculates and sets the required
following distance to the preceding vehicle.
The set distance will be shown in the right

GWarning!
It is up to the driver to exercise discretion to
select the appropriate setting given road
