Introduction
For information on driving with an automatic
transmission, see “Driving and parking”
(Y page 285). G
Warning!
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.
i During the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more quickly
to operating temperature. Gear selector lever

Warning!
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.
! Only shift the automatic transmission into
reverse gear R or park position P when the
vehicle is stopped. Otherwise the
automatic transmission could be damaged. Automatic transmission

Effect
A
Neutral 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 ESC 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

Selecting program mode C means:
R
The vehicle starts out more gentle, both
forward and reverse, except when driving
off with full throttle.
R Traction and driving stability are improved
on icy roads.
R Upshifts occur earlier even when you give
more gas. The engine then operates at
lower revolutions and the wheels are less
likely to spin.
Selecting program mode S means that
upshifts occur later. One-touch gearshifting
With the automatic transmission in drive
position D and driving in automatic program
mode C or S, you can limit or extend the gear
range using the steering wheel gearshift
control.
AMG vehicles: For information on using the
steering wheel gearshift control in manual
program mode M, see “Manual shift program”
(Y page 298). Steering wheel gearshift control (example
illustration)

position N, or reverse gear R. Limiting gear range G
Warning!
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.
X Briefly 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.
i To 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 X
Briefly 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.
i If 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 X
