mission position h. This automatic gear shift-
ing behavior is determined by:
Ra shift range restriction, if selected
Rthe position of the transfer case ( HIGH
RANGE orLOW RANGE )
Rthe position of the accelerator pedal
Rthe road speed
Driving tips
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts

In the manual drive program you can change
gears manually using steering wheel paddle
shifters :and ;(
Ypage 117).
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 Con Mercedes-
AMG vehicles) is characterized by the following:
Rcomfort-oriented engine and transmission
settings.
Roptimal fuel consumption resulting from the
automatic transmission shifting up sooner.
Rthe vehicle pulls away more gently in forward
and reverse gears, unless the accelerator
pedal is depressed fully.
Rincreased sensitivity. This improves driving
stability on slippery road surfaces, for exam-
ple.
Rthe 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 Sis characterized by the follow-
ing:
Rsporty engine and transmission settings.
Rthe vehicle pulling away in first gear.
Rthe automatic transmission shifts up later.
Rthe fuel consumption possibly being higher as
a result of the later automatic transmission
shift points.
Shift ranges
Introduction
It is not possible to set the shift range on
Mercedes-AMG vehicles.
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 multi-
function display. The automatic transmission
shifts only as far as the selected gear.
Driving situations
=You can use the engine's braking
effect
5You can use the engine's braking
effect
This setting is particularly suited for
driving:
Ron steep mountain roads
Rin mountainous terrain
Rin arduous conditions
4The braking effect of the engine can
be utilized on extremely steep down-
hill gradients and long downhill
stretches.
Restricting the shift range
XPull the left-hand steering wheel paddle
shifter (Ypage 116).
The automatic transmission shifts down one
gear and restricts the shift range to the rele-
vant gear.
To protect against engine damage, the auto-
matic transmission:
Rdoes not shift down if doing so would cause
the engine to exceed the maximum engine
speed
Rshifts up, even if the shift range is restricted,
if the maximum engine speed for the shift
range is reached and you continue to accel-
erate
