For more information, see the “Practical
hints” section (
page 327) and
(
page 335).Electronic traction system
The electronic traction system is a
component of ESP
®.
The electronic traction system improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
When you switch off the ESP
®, the
electronic traction system is still enabled.Switching off the ESP
®
To improve the vehicle’s traction, turn off
the ESP® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:
when driving with snow chains
in deep snow
in sand or gravel
!Vehicles without 4MATIC:
Because the ESP® operates automatically, the
engine must be turned off (SmartKey in starter
switch position0 or1) when
the parking brake is being tested on a brake
test dynamometer
the vehicle is being towed with the front axle
raised
Active braking action through the ESP
® may
otherwise seriously damage the brake system.
For information on vehicles with 4MATIC, see
“Four wheel electronic traction system (4MATIC)
with the ESP
® ” (page 88).
iThe ESP® will only function properly if you
use wheels of the recommended tire size
(
page 403).
Warning!G
If you are driving too fast, the electronic
traction system cannot reduce the risk of an
accident.
The electronic traction system cannot pre-
vent the natural laws of physics from acting
on the vehicle.
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 stan-
dard driving maneuvers.
Do not switch off the ESP
® when a
Minispare wheel is mounted.
!Switch on the ESP® immediately if the
aforementioned circumstances do not apply
anymore.

Driving safety systems
Four wheel electronic traction system
(4MATIC) with the ESP®
Models with all-wheel-drive only.
The 4MATIC improves vehicle’s ability to
use available traction, e.g. during winter
operation in mountains under snowy
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
Limited Warranty.
!Because the ESP® operates automatically,
the engine must be shut off (SmartKey in starter
switch position0 or1) when the parking brake is
being tested on a brake test dynamometer.
Active braking action through the ESP
® may
otherwise seriously damage the front or rear axle
brake system.
Operational tests with the engine running can
only be conducted on a two-axle dynamometer.
iAt highly demanding operating conditions,
the electronic traction system may temporarily
switch off to prevent overheating of the drive
wheel brakes. The message

the multifunction display while the ESP® warning
lampv is flashing. The ESP® is still function-

Anti-theft alarm system*
Once the alarm system has been armed, a
visual and audible alarm is triggered when
someone opens
a door

The alarm will stay on even if the activating
element (e. g. a door) is immediately
closed.The alarm system will also be triggered
when
opening the vehicle with the
mechanical key
someone opens a door from the inside
someone opens the trunk with the
emergency release button
iStarting the engine will also deactivate the
immobilizer.
In case the engine cannot be started (yet the ve-
hicle’s battery is charged), the system is not op-
erational. Contact an authorized Mercedes-Benz
Center or call 1-800-FOR-MERCedes (in the
USA), or 1-800-387-0100 (in Canada).
iIf 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 247) provided Tele Aid service was
subscribed to and properly activated, and that
necessary cellular service and GPS coverage are
available.
