14 Introduction
Operator’s Manual
Warning!G
This Sport Utility Vehicle is designed for both on-road and off-road use. It can go places and perform tasks for which conventional 2-wheel drive
passenger cars are not intended. This vehicle will handle and maneuver differently from conventional passenger cars in driving conditions which
may occur on streets, highways and off-road use.
This vehicle has a higher ground clearance and a higher center of gravity than many passenger cars. As with other vehicles of this type, if you make
sharp turns at excessive speeds or abrupt maneuvers, the vehicle may roll over or may go out of control and crash. Utility vehicles have a signifi-
cantly higher rollover rate than other types of vehicles. Failure to operate this vehicle safely may result in an accident, rollover of the vehicle, and
severe or fatal injury.
Before you start to drive this vehicle, read the Operator’s Manual. Take time to become familiar with the driving characteristics of this vehicle. Be
sure you are familiar with all vehicle controls. Learn how your vehicle handles on different road surfaces. Do not attempt sharp turns at excessive
speeds or abrupt maneuvers or other unsafe driving actions that can cause loss of vehicle control. When driving off-road or working the vehicle
hard, do not overload it. And, always wear your seat belts at all times. In a rollover crash, an unbelted person is significantly more likely to die than
a person wearing a seat belt.

!Shift the automatic transmission to
positionPorR only when the vehicle is stopped
in order to avoid damaging the transmission.
!Do not run cold engine at high engine
speeds. Running a cold engine at high engine
speeds may shorten the service life of the
engine.
ML 63 AMG:
At engine temperatures below 68°F (20°C), the
engine’s maximum speed is restricted in order to
protect it from damage. Avoid driving your vehi-
cle at full speed when the engine is cold to pre-
vent premature engine wear and/or diminished
comfort.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.

99 Safety and Security
Driving safety systems
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take extra
care while driving.Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
Off-road – ABS
With the off-road driving program switched
on (
page 253), the ABS designed for
off-road use is automatically activated.
When applying the brakes at speeds below
approximately 18 mph (30 km/h), the
front wheels are locked cyclically to short-
en the braking distance (dig-in effect). This
affects steering the vehicle.
For more information, see “Practical hints”
(
page 399).
Warning!G
When the ABS is malfunctioning, the BAS,
the ESP®, and the 4-ETS are also switched
off. The basic driving and braking functions
are still available.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the brak-
ing distance.
Warning!G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded. The ABS cannot prevent acci-
dents, including those resulting from
excessive speed in turns, following another
vehicle too closely, or hydroplaning. Only a
safe, attentive, and skillful driver can pre-
vent accidents. The capabilities of an ABS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.

103 Safety and Security
Driving safety systems
Switching on the ESP®
Press ESP® switch1.
The ESP
® warning lampv in the
instrument cluster goes out.
You are now again in normal driving
mode.For more information, see “Practical hints”
(
page 399).
Off-road – ESP
®
With the off-road driving program switched
on (
page 253), the ESP® designed for
off-road use is automatically activated. At
speeds below 27 mph (45 km/h), the
ESP
® assists in over-/understeering, thus
improving vehicle traction.
ESP
® Trailer Stabilization
If the trailer you are towing should begin to
sway, the rig can only be stabilized by
immediately applying the brakes hard.
Steering during this maneuver will not help
to stabilize the rig.
ESP
® will assist you in such situations.
ESP® recognizes when the trailer starts
swaying and will apply the brakes to re-
duce the vehicle speed to a non-critical
speed that allows the vehicle-trailer combi-
nation to stabilize.The ESP
® Trailer Stabilization is functional
at vehicle speeds above approximately
40 mph (65 km/h) when the ESP
® is
switched on.
Warning!G
When the ESP® warning lampv is
illuminated continuously, the ESP® is
switched off or is not operational due to a
malfunction.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!Avoid spinning of a drive wheel for an ex-
tended period of time with the ESP® switched
off. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
WarningG
The system will not be able to assist when
the trailer jackknifes

on wet or icy roads

on roads with slippery surface

in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying
of the trailer.
iIf the ESP® has switched off due to a mal-
function, ESP® cannot stabilize the rig.

104 Safety and Security
Driving safety systems
EBP
The EBP enhances braking effectiveness
by allowing the rear brakes to supply a
greater proportion of the braking effort
without a loss of vehicle stability.
For more information, see the “Practical
hints” section (
page 402) and
(
page 429).
4-ETS
The 4-Electronic Traction System (4-ETS)
improves the vehicle’s ability to utilize
available traction, especially under
slippery road conditions. The brakes are
applied to the spinning wheel and power is
transferred to the wheel(s) with traction.
The ESP
® warning lampv in the instru-
ment cluster, starts to flash at any vehicle
speed, as soon as a tire loses traction and
the wheel begins to spin.
Warning!G
If the EBP is malfunctioning, the brake sys-
tem is still functioning. However, the rear
wheels may lock during hard braking, caus-
ing you to lose control over the vehicle and
possibly causing an accident. Adjust your
driving style to the non-operating status of
the EBP.
iIf conditions require, switch on off-road
driving program (
page 253).
Warning!G
When you see ESP® warning lampv
flashing in the instrument cluster, then pro-
ceed as follows:

While driving off, apply as little throttle
as possible.

While driving, ease up on the accelera-
tor.

Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4-ETS cannot prevent accidents resul-
ting from excessive speed.

105 Safety and Security
Driving safety systems
For more information, see the “Practical
hints” section (
page 400) and
(
page 413).
Off-road - 4-ETS
With the off-road driving program switched
on (
page 253), the 4-ETS designed for
off-road use is automatically activated.
!Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!Because the ESP® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO* start/stop button in
position0or1) when testing the parking brake
on a brake test dynamometer and such testing
should be no longer than 10 seconds.
Active braking action through the ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
iIf the yellow ESP® warning lampv
comes on while driving, the 4-ETS is being
switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the
message
ESP Unavailable See Operator’s
Manual
appears in the multifunction display.
