4.1.6 Lamp test/comparison of the switching states
Lamp test After the ignition has been switched on, a lamp test is performed.
• Check that the lamps (1) light up briefly, if they
are present. If the specified time is insufficient,
switch on the ignition again.
• If necessary, engage the parking brake and
check that the lamp (2) lights up continuously.
Comparison of the
switching states
When the ignition is switched on, the switching states of the differential locks and
the steering are compared.
The switching procedures for the last stored
states are selected.
The symbols (1) and (2) show the selected states.
If a symbol (1) shows an intermediate position
(yellow), you must actuate the steering, or drive
slowly forwards and backwards, so that the
locking processes are completed mechanically.
S
Risk of accident from faulty lamps!
The lamps that are used to provide warnings and information during operation
light up for control purposes whenever the ignition is switched on. Always per-
form the following lamp tests and immediately replace faulty lamps or have them
replaced!
In this way, you will avoid accidents and damage that occur when malfunctions
are not identified in time.
