Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R Cruise control, Distronic* and Speedtronic,
which are used to control the speed of the
vehicle
R AIRMATIC package*, consisting of level
control* for individual adjustment of
ground clearance and ADS* (Adaptive
Damping System), for individual adjust-
ment of suspension tuning
R Parktronic*, which assists you in parking
and manoeuvring
R Reversing camera*, which assists you
when parking and manoeuvring
The ABS, BAS, ESP ®
, EBV and 4-ETS vehicle
safety systems and the distance warning sys-
tem* are described in the "Safety" section
(Y page 57). Cruise control
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or 3in good time. By
doing so you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to
assist driving. You are responsible for the vehicle's speed and for braking in good
time.
G
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do
not allow you to maintain a constant
speed (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
R on slippery roads. Braking or accelerat-
ing could cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to
fog, heavy rain or snow
Cruise control lever You can operate cruise control and variable
Speedtronic with the cruise control lever.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:

ML 63 AMG The AIRMATIC package is part of the standard
equipment. Due to the sportier suspension
tuning when compared to standard vehicles,
the level positions in the ADS settings and the
speed thresholds for raising and lowering the
vehicle are different.
The vehicle is lowered from highway/high-
speed to ADS Sport level around 20 seconds
after locking. The vehicle is not lowered from
the raised level after locking. When starting
the engine, the previous setting, e.g. ADS
COMF, is restored.
!
Always keep in mind the differences in
ground clearance and vehicle height when
compared to standard vehicles. You could
otherwise damage the vehicle.
You will find different values for ground clear-
ance and vehicle height with regard to:
R off-road driving (Y page 235)
R the general vehicle settings in the "Techni-
cal Data" section (Y page 361) ADS* (Adaptive Damping System)
ADS adapts the damping characteristics to
the current operating and driving situation.
How this is adjusted depends on:
R your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the key from the ignition lock. Vehicle with AIRMATIC package*

tems 158 Level control*
The level control adapts the vehicle level
automatically to the current operating and
driving situation. This results in reduced fuel
consumption and improved handling.
When you are driving in ADS* COMFor
AUTO (Ypage 157), the vehicle is lowered to
the high-speed level as the speed increases.
As the vehicle decelerates, the vehicle is
raised back up to highway level.
In ADS* SPORT(Ypage 157), the vehicle
skips highway level and lowers directly to the
high-speed level depending on the basic set-
ting (Y page 158) or (Y page 160).
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as pos-
sible.
The vehicle level may change visibly when you
park the vehicle and the outside temperature
changes. When the temperature drops, the
vehicle level is lower; with an increase in tem-
perature, the vehicle level rises.
When you unlock the vehicle or open a door,
the vehicle begins to balance the load dis-
crepancies while still parked. However, for
significant level changes, e.g. after the vehi-
cle has been stationary for a long period, the engine must be on. For safety reasons, the
vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened and continues when the door has
been closed. G
Risk of injury
Make sure that nobody is in the vicinity of
the wheel arch or the underbody when you
begin a level change. You could otherwise
trap yourself or others. G
Risk of accident
Always select as low a vehicle level as pos-
sible. If the vehicle level is high, the vehicle
centre of gravity shifts upwards. This
increases the risk of the vehicle tipping
over.
Adapt your driving style to suit the vehicle
level. ESP ®
cannot reduce the risk of an
accident if you drive too fast. ESP ®
cannot
override the laws of physics.
! When driving on extremely rough terrain,
select a high vehicle level in good time.
Make sure there is always sufficient ground
clearance to prevent damage to the vehi-
cle. You will find information about driving off-
road in the "Operation" section
(Y
page 235).
Vehicles with AIRMATIC package* Basic settings, excluding ML 63 AMG
The extent to which the vehicle is raised or
lowered depends on the basic setting selec-
ted. Select raised level for off-road driving or
highway/high-speed level for normal roads.
The individual vehicle levels are:
R
Raised level: 60 mm above highway level
R Highway level: +/- 0 mm
R High-speed level: 15 mm below highway
level
Basic settings for the ML 63 AMG
The extent to which the vehicle is raised or
lowered depends on the ADS setting selec-
ted. Select raised level for off-road driving or
highway/high-speed level for normal roads.
With AUTO ADS, the vehicle is 73 mm higher
when in raised level than it is in highway level.
Raised level
Only select the raised level when this is appro-
priate for the road conditions. Otherwise, fuel Controls

Points to remember
G
Risk of accident
Drive slowly in rough terrain with which you
are unfamiliar. This will allow you to detect
unexpected obstacles more easily and to
therefore reduce the risk of an accident.
Do not make U-turns on mountain roads.
The vehicle could otherwise tip over. If a
slope is too steep for the vehicle, drive back
in reverse gear.
Do not drive at an angle up steep inclines.
The vehicle could otherwise tip over. If you
drive up a steep incline at an angle and the
vehicle threatens to overturn, steer into the
line of fall immediately.
Never allow the vehicle to roll backwards.
The braking effect of the engine cannot be
utilised in neutral. If you only use the
service brake, you could lose control of the
vehicle. G
Risk of accident
Grains of sand, particles of dirt and other
abrasive materials can enter the brake sys-
tem. This can lead to excessive wear and
unpredictable braking efficiency. After the brakes have been exposed to dirty
conditions, have them checked and
cleaned at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
There is otherwise a risk that braking power
may be insufficient in the event of an emer-
gency, or that braking efficiency may be
unpredictable.
Read this section before driving your vehicle
off-road. Practise by travelling over more gen-
tle off-road terrain first.
The following driving systems are specially
adapted to off-road driving:
R off-road drive program (Y page 140)
R LOW RANGE* off-road gear (Y page 141)
R off-road ABS (Y page 57)
R off-road 4-ETS (Y page 61)

G
Risk of accident
Damage to the vehicle creates the risk of
an accident for yourself and other road
users. If in doubt, have your vehicle
checked at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
that you use a Mercedes-Benz Service
Centre for this purpose. H
Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
General information R
Stop your vehicle and, if necessary, select
the off-road drive program* (Y page 140)
or the LOW RANGE* off-road gear

R
Ensure that a bow wave does not form as
you drive.
R Clean any mud from the tyre tread after
crossing a ford.
R Apply the brakes to dry them after crossing
a ford. Driving on sand
Observe the following rules when driving on
sand:
R Select a higher vehicle level*.
R Select a shift range appropriate to the ter-
rain.
R Drive quickly to overcome the rolling resist-
ance. The vehicle could otherwise dig itself
into the sand.
R Drive in the tracks of other vehicles, if pos-
sible. Make sure that the ruts are not too
deep, that the sand is firm enough and that
your vehicle has sufficient ground clear-
ance. Ruts
Observe the following rules when driving
along ruts in off-road terrain or on roads with
loose gravel:
! Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged
or bottom out and get stuck.
R Select the off-road drive program
(Y page 140) or the LOW RANGE *off-road
gear (Y page 141).
R Select a higher vehicle level*.
R Avoid high engine speeds.
R Select shift range 1.
R Drive slowly.
R Where ruts are too deep, drive with the
wheels on one side on the middle section
of turf if possible. Driving abroad
Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 216). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. Oncoming traf-
fic will be dazzled less.
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Have your headlamps switched back to
asymmetrical dipped beam if you visit a Operation
