R the position of the transfer case ( HIGH
RANGE or LOW RANGE)
R the position of the accelerator pedal
R the road speed148
Automatic transmission
Driving and parking

Driving tips
Accelerator pedal position Your style of driving influences how the
automatic transmission shifts gear:
R
little throttle: early upshifts
R more throttle: late upshifts
Kickdown Use kickdown for maximum acceleration.
X
Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The
automatic transmission shifts back up.
Rocking the vehicle free Rocking the vehicle free by shifting back and
forth between transmission positions
D and
R can help to free a vehicle that has become
stuck in mud or snow. The vehicle's engine
management restricts repeated shifting
between transmission positions D and R up
to a maximum speed of up to

5 mph
(9 km/h). To shift back and forth between
transmission positions D and R, move the
selector lever forwards and backwards past
the point of resistance.

In the automatic drive program, you can
restrict or derestrict the shift range by using
steering wheel paddle shifters
: and ;
(Y page 150).
In the manual drive program you can change
gears manually using steering wheel paddle
shifters : and ;(Y page 151).
i You can only change gear with the
steering wheel paddle shifters when the
transmission is in position D. Automatic drive program
Drive program E (drive program C on AMG
vehicles) is characterized by the following:
R comfort-oriented engine and transmission
settings
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully R
increased sensitivity. This improves driving
stability on slippery road surfaces, for
example
R the automatic transmission shifting up
sooner. This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin
Drive program S is characterized by the
following:
R sporty engine and transmission settings
R the vehicle pulling away in first gear
R the automatic transmission shifting up
later
R the fuel consumption possibly being higher
as a result of the later automatic
transmission shift points Shift ranges
Introduction When the automatic transmission is in
position D, it is possible to restrict or
derestrict the shift range.
The shift range selected is shown in the
multifunction display. The automatic
transmission

shifts only as far as the selected
gear.
Driving situations =
You can use the engine's braking
effect.

The braking effect of the engine can
be utilized on downhill gradients or
when driving:
R
on steep mountain roads
R in mountainous terrain
R in arduous conditions 4
The braking effect of the engine can
be utilized on extremely steep
downhill gradients and long
downhill stretches.150

Restricting the shift range
X
Pull the left-hand steering wheel paddle
shifter (Y page 150).
The automatic transmission shifts down
one
gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the
automatic transmission protects against
engine damage by not shifting down.
i If

the maximum engine speed for the shift
range is reached and you continue to
accelerate, the automatic transmission
shifts up in order to prevent the engine
from overrevving, even if the shift range is
restricted.
Derestricting the shift range X
Pull the right-hand steering wheel paddle
shifter (Y page 150).
The automatic transmission shifts up one
gear and restricts the shift range to the
relevant gear.
Clearing the shift range restriction X
Pull and hold the right-hand steering wheel
paddle

shifter (Y page 150) until D is shown
again in the multifunction display.
The automatic transmission shifts from the
current shift range directly to D.
Selecting the ideal shift range X
Pull the left-hand steering wheel paddle
shifter

(Y page 150) and hold it in position.
The automatic transmission shifts to the
gear which allows optimum acceleration
and deceleration. To do this, the automatic
transmission shifts down one or more
gears.
i The automatic transmission cannot shift
down beyond second gear. To shift to first
gear, you have to pull the left steering
wheel paddle shifter. Manual drive program
Introduction In drive program M, you can change gear
manually using the steering wheel paddle
shifters.

For this, the transmission must be in
position D. The gear currently selected and
engaged is shown in the multifunction
display.
Manual drive program M differs from drive
programs E and S with regard to spontaneity,
responsiveness and smoothness of gear
changes.

Press the program selector button
(Y

page 149) repeatedly until M appears in
the multifunction display.
Upshifting (except AMG vehicles) X
Pull the right-hand paddle ( Y page 150).
The
automatic transmission shifts up to the
next gear.
Shifting up (AMG vehicles) !
In
manual drive program M, the automatic
transmission does not shift up
automatically even when the engine
limiting speed for the current gear is
reached. When the engine limiting speed is
reached, the fuel supply is cut to prevent
the engine from overrevving. Always make
sure that the engine speed does not reach
the red area of the tachometer. There is
otherwise a risk of engine damage.
X Pull the right-hand paddle ( Y page 150).
The
automatic transmission shifts up to the
next gear.
Before the engine speed reaches the red area,
an upshift indicator will be shown in the

i If you slow down or stop without shifting
down, the automatic transmission
automatically shifts down.
Selecting the optimal gear for
maximum acceleration X
Pull the left-hand steering wheel paddle
shifter until the transmission selects the
optimum gear for the current speed.
Kickdown You can also use kickdown for maximum
acceleration in manual drive program
M.
X Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Shift back up once the desired speed is
reached.
i Vehicles with an AMG engine: it is not
possible to use kickdown in manual drive
program M.
i Vehicles

without an AMG engine: if you
apply full throttle, the automatic
transmission shifts up to the next gear
when the maximum engine speed is
reached. This prevents the engine from
overrevving.
