Driving safety systems
4-ETS
The 4-Electronic Traction System (4-ETS)
improves the vehicle’s ability to utilize
available traction, especially under slip-
pery road conditions. The brakes are ap-
plied to the spinning wheel and power is
transferred to the wheel(s) with traction.
The ESP
® warning lampvin the instru-
ment cluster starts to flash at any vehicle
speed, as soon as a tire loses traction and
the wheel begins to spin.
For more information, see the “Practical
hints” section (
page 420) and
(
page 433).
Warning!G
When you see the ESP® warning lampv
flashing in the instrument cluster, then pro-
ceed 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 4-ETS cannot prevent accidents resul-
ting from excessive speed.
!Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck 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 position0 or1 or
KEYLESS-GO* start/stop button in
position0or1) when testing the brakes on a
brake test dynamometer and such testing should
be no longer than 10 seconds.
Active braking action through ESP
® may other-
wise seriously damage the brake system which is
not covered by the Mercedes-Benz Limited
Warranty.
iIf the yellow ESP® warning lampv
comes on while driving, the 4-ETS is being
switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the
message
ABS, ESP unavailable See
Operator’s Manual
appears in the
multifunction display.
