Make sure the differential locks are switched
on at all times except when driving off-road
for example. Switch on the differential locks
immediately when returning from off-road
driving.
i In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.
ABS (Anti-lock Braking System)
Important safety notes
GWarning
Observe "Important safety notes"
( Y page 55).
GWarning
Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS operates above a speed of about
5 mph(8 km/h) regardless of road-surface
conditions, provided the differential locks are
not active. ABS works on slippery surfaces,
even when you only brake gently.
The ! warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Braking
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking
situation is over.XTo make a full brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.
GWarning
If the ABS malfunctions, other driving systems
such as the BAS or the ESP ®
are also switched
off. Observe indicator and warning lamps that
may come on as well as messages in the
multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.
Off-road ABS
If the LOW shift range ( Y page 126) is
selected on the transfer case, an ABS system
specifically suited to off-road terrain is
activated.
At speeds below 37 mph(60 km/h) , the front
wheels lock periodically when braking. The
digging-in effect achieved in the process
reduces the stopping distance on off-road
terrain. This limits steering capability.
BAS (Brake Assist)
GWarning
Observe "Important safety notes"
( Y page 55).
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.

cluster display.
! If the transmission position display in the
multifunction display is not working, you
should pull away carefully to check whether
the desired transmission position is
engaged. Select transmission position D.
Do not restrict the shift range.
Displays on the cover beside the selector
lever also indicate the current position of the
selector lever.
The displays light up when the SmartKey is
inserted into the ignition lock. The displays go
out when the SmartKey is removed from the
ignition lock.
When the selector lever is in position D, you
can influence the gearshifts made by the
automatic transmission by:
R restricting the shift range
R changing gear yourself
Transmission positions
BPark position
Do not shift the transmission into
position P(Y page 134) unless the
vehicle is stationary. The parking
lock should not be used as a brake
when parking. In addition to
engaging the parking lock, you
must always apply the parking
brake to secure the vehicle.
i The SmartKey can only be
removed if the transmission is in
position P. When there is no
SmartKey in the ignition lock, the
selector lever is locked in
position P.
If the vehicle electronics are
malfunctioning, the selector lever
may be locked in position P. To
release a locked selector lever, see
"Manual override of parking lock"
( Y page 126).
Have the vehicle electronics
checked immediately at a qualified
specialist workshop, e.g. an
authorized Mercedes-Benz Center.CReverse gear
Only shift the transmission to R

ANeutral
No power is transmitted from the
engine to the drive wheels.
Releasing the brakes will allow you
to move the vehicle freely, e.g. to
push it or tow it.
Do not shift the transmission to N
while driving. Otherwise, the
automatic transmission could be
damaged.
If ESP ®
is deactivated or faulty:
only shift the transmission to
position N if the vehicle is in danger
of skidding, e.g. on icy roads.
If you want to engage the transfer
case, shift briefly into N
( Y page 126).
! Rolling in neutral N can damage
the drive train.7Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
Changing gears
The automatic transmission shifts to the
individual gears automatically when it is in
transmission position D. This automatic
gearshifting behavior is determined by:
R a shift range restriction, if selected
R the position of the transfer case ( HIGH or
LOW )
R the position of the accelerator pedal
R the road speed
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.
XDepress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Working on the vehicle
GWarning
When working on the vehicle, engage the
parking brake and shift AUTOTRONIC into
park position P. Otherwise the vehicle could
roll away which could result in an accident
and/or serious personal injury.
Shift ranges
Introduction
When the automatic transmission is in
position D, it is possible to restrict or
derestrict the shift range ( Y page 123).
Automatic transmission123Driving and parkingZ

:Shift range selected;Current transfer case position
Selected shift range : and current transfer
case position ; are shown in the cluster
multifunction display. The automatic
transmission shifts only as far as the selected
gear.
! When the transfer case is in the off-road
driving position LOW range, the automatic
transmission does not shift up, even when
the engine has reached the overrevving
limit. There is then a risk of engine damage.
Make sure that you do not exceed the
maximum permissible engine speed.
Driving situations=You can use the engine's braking
effect.5To 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 conditions4To use the braking effect of the
engine on extremely steep downhill
gradients and on long downhill
stretchesRestricting the shift rangeXPress the selector lever to the left towards
D– .
The automatic transmission shifts down to
the next gear, depending on the gear
currently selected. This also restricts the
shift range.
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
XBriefly press the selector lever to the right
towards D+.
The automatic transmission shifts up to the
next gear, depending on the shift range
selected. This also derestricts the shift
range.
Clearing the shift range restriction
XPress and hold the selector lever towards
D+ until D is shown once more in the
multifunction display.
The automatic transmission shifts from the
current shift range directly to D.
Selecting the ideal shift range
XPress the selector lever to the left towards
D– 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.

Shifting the transfer case
General notes
GWarning!
Always wait until the procedure of shifting
from HIGH to LOW – and from LOW to HIGH
– has been entirely completed. During this
procedure do not turn off the engine or shift
the automatic transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This
could lead to an accident and cause injury to
yourself and others.
