Activating cruise control
You can activate the cruise control when
the vehicle speed is above
20 mph (30 km/h).
In the following cases you cannot activate
the cruise control:

when you brake


when you have set the parking brake


when the automatic transmission is set
to positionP, R, or N


if the ESP
® is switched off


if the ESP
® has switched off due to a
malfunctionSetting current speed

Accelerate or decelerate to the desired
speed.

Briefly lift the cruise control lever in
direction of arrow1 or depress in
direction of arrow2.
The current speed is set.

Remove your foot from the accelerator
pedal.
The cruise control is activated.
The current set speed appears in the
multifunction display for approximately
5 seconds.Canceling cruise control
There are several ways to cancel the cruise
control:

Step on the brake pedal.
The cruise control is canceled. The last
speed set is stored for later use.
or

Briefly push the cruise control lever in
direction of arrow3 (
page 246).
The cruise control is canceled. The last
speed set is stored for later use.
i
The vehicle speed displayed in the speedom-
eter can briefly vary from the speed setting for
the cruise control system.
i
On uphill grades, the cruise control may not
be able to maintain the set speed. Once the
grade eases, the set speed will be resumed.
On downhill grades, the cruise control maintains
the set speed by braking with the vehicle’s
braking system. In addition, on longer downhill
grades the automatic transmission will down-
shift automatically.
i
The last stored set speed is canceled when
the engine is turned off.

Decelerate the vehicle speed to a value that
the prevailing road conditions permit. Other-
wise, sudden and unexpected deceleration
of the vehicle could cause an accident
and/or serious injury to you and others.i

The Distronic resumes to the last set
speed.

Remove your foot from the accelerator
pedal.

264 Controls in detailDriving systemsDownhill Speed Regulation (DSR)For more information, see “Off-road driv-
ing” (
page 333).
The DSR is an aid for driving downhill. DSR
regulates your vehicle’s speed when driv-
ing downhill to the value set in the control
system (page 179). The steeper the
downhill gradient is, the greater the brake
application. On flat road surfaces, DSR
brakes only slightly or not at all.
DSR regulates the vehicle’s speed in auto-
matic transmission positionsD, orR.
You can drive slower or faster than the set
speed at any time by braking the vehicle or
depressing the accelerator pedal.
Warning!
G
Downhill Speed Regulation is a convenience
system designed to assist the driver during
vehicle operation. The system must be set
to be appropriate for the topographical and
weather conditions encountered which can
change quickly. The driver is and must
remain at all times responsible for the vehi-
cle speed and for safe brake operation.
Depending on the programmed speed
(page 179), actual vehicle speed and gra-
dient, switching on the DSR while driving
can cause the vehicle to slow down rapidly
and you may hear a sound which is caused
by the activation of the vehicle’s brake sys-
tem through the DSR. Sudden and unex-
pected deceleration can result in loss of
vehicle control, causing an accident and/or
serious personal injury to you and others.
Do not switch on the DSR in a circumstance
where rapid deceleration could result in a
loss of vehicle control.
i
In addition, make use of the engine’s braking
effect by shifting the automatic transmission
into a lower gear.
i
Whenever DSR is switched on, DSR will use
the programmed default speed to regulate the
vehicle’s speed. The default speed programmed
at the factory is 4 mph (Canada: 6 km / h). The
default speed can be reprogrammed using the
control system (
page 179). The next time DSR
is switched on, DSR will use the newly pro-
grammed default speed to regulate the vehicle’s
speed.
Once DSR is switched on, you can adjust the set
speed using the cruise control lever
(
page 255). Keep in mind that adjusting the
set speed using the cruise control lever with DSR
switched on will not change the programmed
default speed. If DSR is switched off and then
switched on again, DSR will use the programmed
default speed.
Depending on the road surface and level of
downhill grade, the DSR may not be able to
maintain the set speed. To maintain the set
speed, apply the brakes if necessary.

268 Controls in detailDriving systemsOff-road driving program
The off-road driving program is designed to
assist the driver when driving off-road in
terrain and crossing water. The off-road
driving program adjusts the engine power
and shifting of the automatic transmission
to be more suitable for the off-road use of
the vehicle. In addition, the ABS, ESP
®, and
4-ETS designed for off-road use are
automatically activated.
In the following situations you should
switch to the off-road driving program:


during off-road driving


when crossing water (
page 338)


when towing up or down on steep
gradientsThe switch is located on the lower part of
the center console.

In the ML 63 AMG, the off-road driving
program is switched on and off via the control

Air suspension package*
The system consists of two components.
The vehicle level control* regulates the
ride height of the vehicle. The Adaptive
Damping System (ADS)* optimizes your
vehicle’s suspension tuning.

i
The Air suspension package is part of the
standard equipment range. Due to the vehicle’s
sportier suspension tuning, in comparison with
standard vehicles, the level positions in the ADS
settings as well as the speed thresholds for rais-
ing and lowering the vehicle have been modified.
i
From the Highway/High-speed level, the
vehicle is lowered to the ADS Sport level approx.
20 seconds after it is locked.
From the raised level, the vehicle is not lowered
after it is locked.
When the engine is started, the previously se-
lected setting, e.g. ADS COMF, is selected again.
!
Be sure to observe this vehicle’s differing
values for ground clearance and vehicle height in
comparison to standard vehicles. You could oth-
erwise damage the vehicle. The values for
