For more information, see “Practical hints”
(page 344).Switching off the ESP
®
To improve the vehicle’s traction, switch
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:


starting out on slippery surfaces and in
deep snow in conjunction with snow
chains


in sand or gravel
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.
iDistronic* is switched off when the
ESP
® engages.
iThe ESP
® will only function properly if
you use wheels of the recommended
tire size (page 426).
!Because of the ESP’s
® automatic oper-
ation, 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 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 otherwise seriously damage the
brake system.
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.
iDistronic* cannot be activated when
the ESP
® has been switched off.

83 Safety and Security
Driving safety systems
When 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 brake a
spinning wheel


the ESP
® continues to operate when
you are brakingThe switch is located on the upper part of
the center console.
1ESP
® off/on

Press ESP
® switch1 until the ESP
®
warning lampv in the speedometer
comes on.
The ESP
® is switched off.
Switching on the ESP
®

Press ESP
® switch1.
The ESP
® warning lampv in the in-
strument cluster goes out.
You are now again in normal driving
mode with the ESP
® switched on.
iWhen the ESP
® is switched off and one
or more drive wheels are spinning,
the ESP
® warning lampv in the in-
strument cluster flashes. However,
the ESP® will then not stabilize the ve-
hicle.
Warning!
G
When the ESP
® warning lampv is illumi-
nated continuously, the ESP
® is switched
off.
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
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.

84 Safety and SecurityDriving safety systemsFour 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 snowy con-
ditions, by applying power to all four
wheels.
Warning!
G
If you see the ESP
® warning lamp v
flashing in the speedometer dial, 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 con-
ducted on a two-axle dynamometer.
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.!Because of the ESP’s
® automatic oper-
ation, the engine and ignition 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 run-
ning can only be conducted on a
two-axle dynamometer.
