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 or KEYLESS-GO start/stop
button in 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.

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 75.
The 4-ETS (four-wheel Electronic Traction
System) are components 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.
When you switch off the ESP
®
, the 4-ETS is
still enabled.
X
If conditions require, switch on the off-road
driving program (
Y
page 169).
Off-road 4-ETS
With the off-road driving program switched on
(
Y
page 169), the 4-ETS designed for off-road
use is activated automatically.
