intermediate cover, contact-discoloration
will be prevented.

comes on while driving.
You engaged the differential locks. The ABS,
ESP, BAS, EBB and 4-ETS are switched off.

The driving systems will switch on
again after the differential locks have
been disengaged.
The ABS has detected a malfunction and has
switched off. The ESP, BAS, EBB and 4-ETS
are also switched off (see messages in dis-
play).
If the ABS control unit is malfunctioning, oth-
er systems such as the navigation system or
Rear Parking Assist* may also malfunction.
The brake system is still functioning normally
but without the ABS available.

Continue driving with added caution.
Wheels will lock during hard braking
reducing steering capability.

Have the system checked at an autho-
rized Mercedes-Benz Light Truck Cen-
ter as soon as possible.

The ABS has switched off because charging
voltage has fallen below 10 volts. The battery
may not be charged.

Turn off unnecessary electric con-
sumers.

value again, the ABS is operational
again.

Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lap stays on.
Do not add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot
engine parts and the brake fluid catching
fire. You could be seriously burned.
!If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.

The yellow “CHECK ENGINE”
malfunction indicator lamp
comes on while driving.
There is a malfunction of:

The fuel management system


The ignition system


The emission control system


Systems which impact emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
mode. Serious damage can occur to the
emission system.

Have the vehicle checked as soon as
possible by an authorized
Mercedes-Benz Light Truck Center.
An on-board diagnostic connector is
used by the service station to link the
vehicle to the shop diagnostics sys-
tem. It allows the accurate identifica-
tion of system malfunctions through
the readout of diagnostic trouble
codes. It is located near the hood lock
release on the upper left of footwell.
The fuel cap is not closed tightly.

Check the fuel cap.
Your gas tank is empty.

After refuelling, start the engine three
or four times in succession. The
limp-home mode is canceled.
