For more information, see “Practical hints”
section (
page 634) and (
page 642).Electronic traction system
The electronic traction system is a compo-
nent of ESP
®.
The electronic traction system improves
the vehicle’s ability to utilize available trac-
tion, especially under slippery road condi-
tions by applying the brakes to a spinning
wheel.
When you switch off the ESP
®, the elec-
tronic traction system is still enabled.
Warning!
G
The ESP
® cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
®
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP
® equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
i
DISTRONIC Plus* and cruise control are
switched off when the ESP
® engages.
i
The ESP
® will only function properly if you
use wheels of the recommended tire size
(
page 754).
!
Vehicles without 4MATIC:
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 position0 or1) when


the electronic parking brake is being tested
on a brake test dynamometer


the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
For information on vehicles with 4MATIC, see
“Four wheel electronic traction system (4MATIC)
with the ESP
®” (page 76).
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.

PRE-SAFE
® Brake* (vehicles with
DISTRONIC Plus* only)
PRE-SAFE
® Brake* can assist you in mini-
mizing the risk of a rear-end collision with
a vehicle in front of you and in reducing the
severity of an accident. At speeds over ap-
prox 20 mph (30 km/h), it will


warn you of a possible collision


automatically begin to brake the vehi-
cle lightly in a speed range of up to
112 mph (180 km/h)


activate preventative occupant safety
measures (PRE-SAFE
®) (page 57)
Warning!
G
If you see the ESP
® warning lampv
flashing in the speedometer, proceed as fol-
lows:


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 Lim-
ited 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 Lim-
ited Warranty.
!
Because the ESP
® operates automatically,
the engine and the ignition must be shut off
(SmartKey in starter switch position0 or1 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 ESP
® may other-
wise seriously damage the front or rear axle
brake system.
Operational tests with the engine running can
only be conducted on a two-axle dynamometer.
Warning!
G
PRE-SAFE
® Brake is a convenience system
designed to assist the driver during vehicle
operation. The responsibility for the vehicle
speed and the distance to the vehicle ahead,
including most importantly brake operation
to assure safe stopping distance, always re-
mains with the driver.


82 Safety and SecurityAnti-theft systemsImmobilizer
The immobilizer prevents unauthorized
persons from starting your vehicle.
When leaving the vehicle, always take the
SmartKey or SmartKey with KEYLESS-GO*
with you, and lock the vehicle. The engine
can be started by anyone with a valid
SmartKey or SmartKey with KEYLESS-GO*
that is left inside the vehicle.
Activating
With the SmartKey: Remove the
SmartKey from the starter switch.

With the KEYLESS-GO*: Turn off the
engine (
page 372) and open the driv-
er’s door.
Deactivating

Switch on the ignition (
page 370).
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 activating
element (a door, for example) is immedi-
ately closed.
The alarm system will also be triggered
when


the vehicle is opened with the
mechanical key


a door is opened from the inside
To cancel the alarm after it has been trig-
gered, see “Canceling the alarm”
(
page 83).
i
Starting 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).
