Mercedes-Benz G-Class 2010 Owners Manual - Manual (Page 56)

ESP ®
G Observe Safety notes, see page 52.
The Electronic Stability Program (ESP ® ) is
operational as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP
® recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the engine output, the
ESP
® works to stabilize the vehicle. The
ESP ® is especially useful while driving off and
on wet or slippery road surfaces. The ESP ®
also stabilizes the vehicle during braking and
steering maneuvers.
The ESP
® warning lamp d in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
The ESP
® warning lamp d in the
instrument cluster flashes when the ESP ® is
engaged.
G Warning!
Never switch off the ESP ® when you see the
ESP ® warning lamp d flashing in the
instrument cluster. In this case proceed as
follows:
R When driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R 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 resulting from excessive
speed.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz 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
position
0 or 1) when the parking brake is
being tested on a brake test dynamometer.
Such testing should be no longer than 10
seconds.
Active braking action through the ESP
®
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.
! The ESP ® will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
Electronic Traction System (4-ETS)
G Observe Safety notes, see page 52.
The 4-ETS (four-wheel Electronic Traction
System) is a component of the ESP
® . The
4-ETS improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. In addition, more power is
transferred to the wheel(s) with traction.
The 4-ETS function is available between
vehicle speeds of 0 mph (km/h) and 37 mph
(60 km/h).
When you switch off the ESP
® , the 4-ETS is
still enabled.

G
Warning!
The ESP ® should not be switched off during
normal driving other than in the
circumstances described below. Disabling
