children unattended in the vehicle, as they
could otherwise accidentally start the engine.
When leaving the vehicle, always take the

not leave children unattended in the vehicle,
or with access to an unlocked vehicle. A

Automatic transmissionGWarning!
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.

vehicle is stopped. Otherwise the
automatic transmission could be damaged.XDepress the brake pedal.

i
Shifting the automatic transmission out of
park position  P is only possible with the
brake pedal depressed.
Without the brake pedal depressed, the
gear selector lever can be moved up or
down. However, the parking pawl remains
engaged, not allowing shifting to occur.
XWait for the gear selection process to
complete before setting the vehicle in
motion.XIf engaged, release the parking brake.XRelease the brake pedal.XCarefully depress the accelerator pedal.
After a cold start, the automatic transmission
shifts at a higher engine speed. This allows
the catalytic converter (gasoline engine) or
the oxidation catalyst (diesel engine) to reach
its operating temperature earlier.

Automatic transmission
Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 103).
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 the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
GWarning!
HYBRID vehicles: It is imperative that you read
the HYBRID Supplemental Operating
Instructions included in your vehicle literature
portfolio. You may otherwise not recognize
potential danger.
! 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 (gasoline engine) or
oxidation catalyst (diesel engine) to heat up
more quickly to operating temperature.

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
Limited Warranty.7Drive position
The automatic transmission shifts
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.
Depending on the engine speed the
automatic transmission shifts into a lower
gear.Rocking the vehicle
Rocking the vehicle by shifting the automatic
transmission directly between drive position
D  and reverse gear  R can help free a vehicle
stuck in mud or snow. The engine control
system of this vehicle electronically limits
directly shifting the automatic transmission
between drive position  D and reverse gear  R
to very low speeds, i.e. approximately 5 mph
( 9 km/h). To shift the automatic transmission
directly between drive position  D and reverse
gear  R, move the gear selector lever up or
down past the resistance point.
Working on the vehicle
GWarning!
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.
Towing a trailer 
XWhen you tow a trailer, shift into a lower
gear range manually if the automatic
transmission hunts between gears on
inclines.
A lower gear range and reduction of speed
reduces the potential to overload or to
overheat the engine.
For more information on trailer towing, see
“Trailer towing” ( Y page 254).
Gear ranges
With the automatic transmission in drive
position  D, you can limit or extend the gear
range, see “One-touch gearshifting”
( Y  page 115).
ML 63 AMG: You only can limit or extend the
gear range when driving in automatic
program mode  C or  S.

One-touch gearshifting
With the automatic transmission in drive
position D, you can limit or extend the gear
range using the steering wheel gearshift
control.
ML 63 AMG: You only can limit or extend the
gear range when driving in automatic
program mode C or S. For information on
using the steering wheel gearshift control in
manual program mode M, see “Manual shift
program” (Y page 115).
Steering wheel gearshift control (exampleillustration)
iYou cannot shift with the steering wheel
gearshift control when the automatic
transmission is in park position P, neutral
position N, or reverse gear R.
Limiting gear range 
GWarning!
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle’s ABS will not prevent
this type of loss of control.
XBriefly pull left gearshift control :.
The automatic transmission will shift into
the next lower gear as permitted by the
shift program. This action simultaneously
limits the gear range of the automatic
transmission.
iTo avoid overrevving the engine when
downshifting, the automatic transmission
will not shift into a lower gear if the engine’s
maximum speed would be exceeded.
Extending gear range
XBriefly pull right gearshift control ;.
The automatic transmission will shift into
the next higher gear as permitted by the
shift program. This action simultaneously
extends the gear range of the automatic
transmission.
iIf you press on the accelerator pedal
when the engine has reached the
revolution limit of the current gear range,
the automatic transmission will upshift
beyond any gear range limit selected.
Canceling gear range limit
XPull and hold right gearshift control ; until
the gear range indicator disappears from
the multifunction display.
The automatic transmission will shift from
the current gear range directly into drive
position D.
Shifting into optimal gear range 
XPull and hold left gearshift control :.
The automatic transmission will select the
gear range suited for optimal acceleration
and deceleration automatically. This will
involve shifting down one or more gears.

to spontaneity, response time, and shifting
smoothness from automatic program mode
