Mercedes-Benz R-Class 2012 Owners Manual - Manual (Page 156)

You can restrict or derestrict the shift range
by using the steering wheel paddle shifters.
Automatic drive program
Drive program E is characterized by the
following:
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 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 ( Y page 154).
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.
5 To use the braking effect of the
engine on downhill gradients and
for driving:
R on steep mountain roads
R in mountainous terrain
R in arduous conditions
4 To use the braking effect of the
engine on extremely steep downhill
gradients and on long downhill
stretches
Restricting the shift range
X Pull the left-hand steering wheel paddle
shifter.
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.
The shift range is derestricted.
Clearing the shift range restriction
X Pull and hold the right-hand steering wheel
paddle shifter until
D is shown again in the
multifunction display.
The automatic transmission shifts from the
current shift range directly to
D.
