Off-road - 4-ETS
With the off-road driving program switched
on (
page 248), the 4-ETS designed for
off-road use is automatically activated.
For more information, see the “Practical
hints” section (
page 382) and
(
page 387).
Warning!
G
When you see ESP
®-warning lampv
flashing in the speedometer, then 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 4-ETS cannot prevent accidents resul-
ting from excessive speed.
!Because of the ESP’s
® automatic oper-
ation, the engine must be shut off
(
page 34) when the parking brake is
being tested on a brake test dynamom-
eter.
Active braking action through ESP
®
may otherwise seriously damage the
brake system.
Operational tests with the engine
running can only be conducted on a
two-axle dynamometer.
iIf the yellow ESP
® warning lampv
comes on while driving, the 4-ETS is be-
ing switched off temporarily to prevent
overheating of the drive wheel brakes.
In addition, the message
ESP unavail-
able See Operator’s Manual
appears
in the multifunction display.
