Switching off the ESP
®
(except E 63 AMG)
To improve the vehicle’s traction, switch
off the ESP
® in driving situations where it
would be advantageous to have drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
in sand or gravelWhen you switch off the ESP
®
the ESP
® does not stabilize the vehicle
the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for better grip
the traction control will still apply the
brakes to a spinning wheel
the ESP
® continues to operate when
you are braking
you cannot activate the cruise control
or the Distronic*
the cruise control or Distronic* switch
off if currently activatedThe switch is located on the center con-
sole.
1ESP
® switch
With the engine running, press ESP
®
switch1 until the ESP
® warning
lampv in the instrument cluster
comes on.
The ESP
® is switched off.
Warning!
G
The ESP
® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in driving
maneuvers.
Do not switch off the ESP
® when a spare
wheel is mounted.
Warning!
G
Switch on the ESP
® immediately if the afore-
mentioned circumstances do not apply any-
more. Otherwise the ESP
® will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.
i
When the ESP
® is switched off and one or
more drive wheels are spinning, the ESP
® warn-
ing lamp v in the instrument cluster flashes.
However, the ESP
® will then not stabilize the ve-
hicle.

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 prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!
Avoid spinning of a drive wheel for an ex-
tended period with the ESP
® switched off. This
may cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
Warning!

The ESP
® should not be switched off during
normal driving. Disabling of the system will
result in the following:
no restriction to engine torque
loss of system supported traction
control
“ESP® O F F ” i s d e s i g n e d f or driving on closed
tracks when the vehicle’s natural oversteer
and understeer characteristics are desired
and requires a highly skilled and experi-
enced driver able to handle these critical
driving situations.
You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch off the ESP
®.
Do not switch off the ESP
® when a spare
wheel is mounted.

Driving safety systems
Four wheel electronic traction system (4MATIC) with the ESP
®
Models with all-wheel-drive only.
The 4MATIC improves the vehicle’s ability
to use available traction, e.g. during winter
operation in mountains under slippery road
conditions, by applying power to all four
wheels.Warning!
G
If you see the ESP
® warning lampv
flashing in the instrument cluster, proceed
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 ESP
® cannot prevent accidents result-
ing from excessive speed.
!
Do not tow with one axle raised.
Otherwise the transfer case can be damaged,
which is not covered by the Mercedes-Benz
Limited Warranty.
!
Performance testing must only be conduct-
ed on a two-axle dynamometer.
Otherwise the transfer case can be damaged,
which is not covered by the Mercedes-Benz

!
Because the ESP
® operates automatically,
the engine and the ignition must be shut off
(SmartKey in starter switch position0 or 1 or
KEYLESS-GO start/stop button* in position0
or1) when the parking brake is being tested on a
brake test dynamometer.
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
Operational tests with the engine running can
only be conducted on a two-axle dynamometer.

Anti-theft alarm system
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens:
a door
the trunk
the hood
The alarm will stay on, even if the activat-
ing element (a door, for example) is imme-
diately closed.
The alarm system will also be triggered
when
the vehicle is opened using the
mechanical key
someone opens a door from the inside
i
In case the engine cannot be started (yet the
vehicle’s battery is charged), the system is not
operational. Contact an authorized
Mercedes-Benz Center or call
1-800-FOR-MERCedes (in the USA), or
1-800-387-0100 (in Canada).
i
If the alarm stays on for more than
30 seconds, a call to the Response Center is ini-
tiated automatically by the Tele Aid system*
(
page 294) provided Tele Aid service was sub-
scribed to and properly activated, and that nec-
essary cellular service and GPS coverage are
available.

Control system
The control system is activated as soon as
the SmartKey in the starter switch is
turned to position1 or as soon as the
KEYLESS-GO start/stop button* is in
position1. The control system enables you
to:
call up information about your vehicle
change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the instrument cluster dis-
play, and much more.
The control system relays information to
the multifunction display.

the language selected.
Warning!
G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

starter switch is turned to position0 or re-
moved from the starter switch.
Warning!
G
Malfunction and warning messages are only
indicated for certain systems and are inten-
tionally not very detailed. The malfunction
and warning messages are simply a remind-
er with respect to the operation of certain
systems and do not replace the owner’s
and/or driver’s responsibility to maintain
the vehicle’s operating safety by having all
required maintenance and safety checks
performed on the vehicle and by bringing
the vehicle to an authorized Mercedes-Benz
Center to address the malfunction and
warning messages (
page 396).
i
The vehicle status message memory will be
cleared when you turn the SmartKey in the start-
er switch to position1 or2. You will then only
see high priority messages in the multifunction
display (

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed
Airmatic DC adjusts the vehicle sus-
pension characteristics automatically
and controls the vehicle level
Parktronic system*, which assists the
driver during parking maneuvers
For information on the BAS, ABS, and
ESP®, see “Driving safety systems”
(
page 97).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed above 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 24).
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always re-
main 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 steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate the cruise control when driv-
ing in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
