Trailer lamp check*
Automatic check
When the trailer has been connected to the vehi-
cle's electrical system, its lamps can be checked
by automatically activating them. This helps the
driver to ensure that the trailer's lamps are func-
tioning correctly before starting to drive.
In order to perform this check, the engine must
not be running.
1. When a trailer is connected to a trailer hitch
or towbar,
Automatic Trailer Lamp Check
will appear in the instrument panel.
2.
Confirm this message by pressing the O but-
ton on the right-side steering wheel keypad.
> The lamp check will begin.
3. Leave the vehicle to perform the trailer lamp
check.
> All of the trailer's lamps will begin to flash
and then each lamp will illuminate one at
a time.
4. Visually check that all of the trailer's lamps
are functioning correctly.
5. After a short time, all of the trailer's lamps
will begin to flash again.
> The lamp check is completed.

Self-leveling suspension*

(up to the max. permissible load). When the
engine is not running, the rear of the vehicle
sinks down slightly, which is normal.
