Roll Bar Warning Lamp
With the key in steering lock position
2, the warning lamp comes on and goes
out with the engine running.
Warning!
If the warning lamp does not go out
after starting the engine, or if it
comes on while driving, and the
indicator lamps in the roll bar switch
blink simultaneously, then the roll
bar system is defective and may not
activate in an accident. In this case,
raise the roll bar manually (see
Index) before continuing to drive.
Have the roll bar system checked at
your authorized MERCEDES-BENZ
dealer as soon as possible.
Seat Belt and Backrest Lock
Warning Lamp
With the key in steering lock position
2, the warning lamp comes on and an
audible warning sounds for a short
time if the driver's seat belt is not
fastened.
If a backrest is not engaged in its lock,
an audible warning will sound
intermittently for up to approx. 20
seconds.
After starting the engine, the warning
lamp blinks for a brief period to
remind the driver and passenger to
fasten seat belts before driving off.
If the warning lamp does not go put
after blinking briefly, but is instead lit
continuously, then a backrest is not
engaged in its lock.
The warning lamp goes out as soon as
the backrest is engaged in its lock.
If the backrest is locked and the
warning lamp does not go out, have
the system checked at your authorized
MERCEDES-BENZ dealer as soon as
possible.
Exterior Lamp Failure Indicator
Lamp
With the key in steering lock position
2, a dim indicator lamp comes on, and
goes out with the engine running.
With the key in steering lock position 2
or with the engine running, a bright
illumination of this lamp indicates an
exterior lamp failure (except high
mounted stop lamp).
If an exterior lamp fails, the indicator
lamp will come on only when that
lamp is switched on.
If a brake lamp fails, the lamp failure
indicator will come on when applying
the brake and stay on until the engine
is turned off.
Note:
The indicator lamp will also come on if
an incorrect bulb is installed.
If additional lighting equipment is
installed (e.g. auxiliary headlamps etc.)
be certain to connect into the fuse
before the failure indicator monitoring
unit in order to avoid damaging the
system.
