ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the key in
steering lock position 2 and should go out
with the engine running.
When the ABS malfunction indicator lamp in the
instrument cluster remains illuminated while the
engine is running, it indicates that the ABS has detected
a malfunction and has switched off. In this case, the
brake system functions in the usual manner, but
without antilock assistance.
With the ABS malfunctioning, the BAS, ESP and 4-ETS+
are also switched off. Both malfunction indicator lamps
come on with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Light Truck Center as soon as possible.
See page 219 for notes on antilock brake system (ABS).Adjustable steering wheel – indicator lamp
The indicator lamp in the instrument cluster
comes on with the key in steering lock
position 2 and should go out with the engine
running.
If the indicator lamp does not go out after starting the
engine, the adjustable steering column is not properly
locked.
For locking the adjustable telescoping steering column,
see page 74.
AIRBAG OFF indicator lamp
The indicator lamp will light up for
approximately 6 seconds, extinguish, then
blink once, when you turn the key in
steering lock to position 1 or 2.
The 7 indicator lamp stays lit as long as a
BabySmart
TM compatible child seat is properly installed
on the front passenger seat. It indicates that the front
passenger airbag is switched off.
