without snow.Please observe the following guidelines
when using snow chains:

Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Light Truck Center.
iWhen driving with snow chains, you
may wish to deactivate the ESP
®
(
page 97) before setting the vehicle
in motion. This will improve the
vehicle’s traction.
!Even on vehicles with all-wheel-drive
use snow chains on rear tires only.
The use of snow chains is not permissi-
ble with the spare wheel.

replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow ABS indicator lamp
comes on while the engine is
running.
ABS has detected a malfunction and has
switched off. The BAS, ESP
®, and 4-ETS are
also switched off (see messages in multifunc-
tion display).
The brake system is still functioning normally
but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as the navigation
system* or the automatic transmission may
also be malfunctioning.

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

Read and observe messages in the
multifunction display (
page 395).

Have the system checked at an
authorized Mercedes-Benz Light
Truck Center as soon as possible.
Failure to follow these instructions
increases the risk of an accident.
The charging voltage has fallen below
ten volts. The ABS has switched off.
The battery might not be charged sufficiently.

Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.

If necessary, have the generator
(alternator) and the battery checked.
When the voltage is above this value
again, the ABS is operational again.

Warning!
G
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lamp stays on. Do not add
brake fluid before checking the brake
system. Overfilling the brake fluid reservoir
can result in spilling brake fluid on hot en-
gine parts and the brake fluid catching fire.
You can 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.
