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

Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the refu-
eling process. otherwise electrostatic charge
could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when adding fuel from a fuel can.
The fuel lines and/or the fuel injection system
could otherwise be blocked by particles from
the fuel can.
If you overfill the fuel tank, fuel could spray out
when the fuel pump nozzle is removed.
