Display of the selected driving program
.
The selected driving program is displayed by light-
emitting diodes next to the rocker switch (illustra-
tion).
The corresponding indicator lights on the instru-
ment panel and light-emitting diodes beside the ro-
cker switch flash several times during the shif-
ting process.
Tip on driving center differential lock
When the center differential lock C is fully enga-
ged, there is no longer any speed difference bet-
ween the front and rear axles. If, for example, both
wheels at the front axle lose traction on an icy
road or soft surface, the rigidly linked drive wheels
will permit the car to continue moving neverthe-
less.
Tip on driving rear-differential lock
When the rear differential lock D is fully engaged,
there is no longer any speed difference between
the two rear wheels. If, for example, one drive
wheel at the rear axle loses traction on an icy road
or soft surface, the rigidly linked drive wheels will
permit the car to continue moving nevertheless.
Note on operation
The rear differential lock can be engaged only
while the engine is running.
