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.
Towing a trailer X
Drive in the middle of the engine speed
range on uphill gradients.
X Limit shift range to 3 or 2 depending
on the
uphill or downhill gradient ( Y page 150),
even if cruise control or SPEEDTRONIC is
activated.
X Shift the transfer case into low-range
driving position LOW RANGE on extreme
uphill gradients or steep

downhill gradients

In the automatic drive program, you can
restrict or derestrict the shift range by using
steering wheel paddle shifters
0043 and 0044
(Y page 150).
In the manual drive program you can change
gears manually using steering wheel paddle
shifters 0043 and 0044(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 0040
You can use the engine's braking
effect.
0038
The braking effect of the engine can
be utilized on downhill gradients or
when driving:
R
on steep mountain roads
R in mountainous terrain

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
