ESP
® G
Observe Safety notes, see page 63.
The Electronic Stability Program (ESP ®
) is
operational as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP ®
recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the engine output, the
ESP ®
works to stabilize the vehicle. The
ESP ®
is especially useful while driving off and
on wet or slippery road surfaces. The ESP ®
also stabilizes the vehicle during braking and
steering maneuvers.
The ESP ®
warning lamp d in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
The ESP ®
warning lamp d in the
instrument cluster flashes when the ESP ®
is
engaged. G
Warning!
Never switch off the ESP ®
when you see the
ESP ®
warning lamp d flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP ®
cannot
prevent accidents resulting from excessive
speed.
! Only

conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized Mercedes-Benz 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
position 0 or 1 or KEYLESS-GO start/stop
button in position 0 or 1) when the parking
brake is being tested on a brake test
dynamometer. 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.
! The ESP ®
will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
i The Distronic system and cruise control
switch off automatically when the ESP ®
engages.
Electronic Traction System (4-ETS) G
Observe Safety notes, see page 63.
The 4-ETS (four-wheel Electronic Traction
System) is a component of the ESP ®
. The
4-ETS

improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. In addition, more power is
transferred to the wheel(s) with traction.
When you switch off the ESP ®
, the 4-ETS is
still enabled.
Switching off the ESP ® G
Warning!
The ESP ®
should not be switched off during
normal driving other than in the Driving safety systems
65

circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP
®
when a spare
wheel is mounted.
To improve the vehicle’s traction, switch off
the ESP ®
. This allows the drive wheels to spin
and thus cut into surfaces for better grip, for
example
R when driving with snow chains
R in deep snow
R in sand or gravel G
Warning!
Switch on the ESP ®
immediately if the
aforementioned circumstances do not apply
anymore. Otherwise the ESP ®
will not
stabilize the vehicle when it is starting to skid
or a wheel is spinning.
When you switch off the ESP ®
,
R the ESP ®
does not stabilize the vehicle
R the engine output is not limited, which
allows the drive wheels to spin and thus cut
into surfaces for better grip
R the 4-ETS will still apply the brakes to a
spinning wheel
R the ESP ®
continues to operate when you
are braking
R the cruise control or the Distronic system
cannot be activated
R the cruise control or the Distronic system
switch off if activated
i When the ESP ®
is switched off and one or
more drive wheels are spinning, the ESP ®
warning lamp d in the instrument
cluster flashes. However, the ESP ®
will
then not stabilize the vehicle. X
With the engine running, press ESP ®
switch : until the ESP ®
warning lamp
d in the instrument cluster comes on.
The ESP ®
is switched off. G
Warning!
When the ESP ®
warning lamp d is
illuminated continuously, the ESP ®
is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving to the prevailing
road conditions and to the non-operating
status of the ESP ®
.
! Avoid spinning of a drive wheel for an
extended period with the ESP ®
switched
off. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
Switching on the ESP ® X
Press ESP ®
switch : until the ESP ®
warning lamp d in the instrument
cluster goes out.
You are now again in normal driving mode
with the ESP ®
switched on.
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.66

Introduction
This section describes the following driving
systems of your vehicle:
R Cruise control
R Distronic
R Distance warning function (only available
with Distronic)
R Hill-start assist system
R Rear-axle level control
R AIRMATIC
R All-wheel drive (4MATIC)
R Parktronic system
R Rear view camera
The

driving safety systems ABS, BAS, EBP and
ESP ®
are described in the “Safety and
security” section (Y page 63). Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The

use of the cruise control is recommended
for driving at a constant speed for extended
periods of time.
The currently set speed or last set speed
(“Resume” function) appears in the status
indicator of the multifunction display:
R USA only: e.g. Cruise 55 Miles
R Canada only: e.g. ¯ 90 Km/h G
Warning!
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only

use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. 142
