ABS display check
&
WARNING Risk of skidding if ABS mal‐
functions
If ABS is malfunctioning, the wheels could
lock when braking. The steerability and brak‐
ing characteristics are thus severely impaired.
#
Drive with even greater care.
#
Have ABS checked at a qualified spe‐
cialist workshop as soon as possible.
The anti-lock protection function is not guaran‐
teed in the following situations:
R
After switching on the ignition, the
!
indi‐
cator lamp is not displayed in the status area
of the instrument cluster/on-board computer.
R
The display is still lit for three seconds after
switching on the ignition.
R
The display is lit after the vehicle is started.
When you switch on the ignition, the
!
indica‐
tor lamp for ABS equipment lights up grey for
approximately three seconds in the status area
(
/
page 153). In addition, the
s
,
r
or
u
indicator lamps for towing vehicles and/or
trailers/semitrailers light up.
If the electronic control detects ABS faults, a cor‐
responding event window appears in the instru‐
ment cluster. A coloured indicator lamp for the
affected ABS equipment also lights up in the sta‐
tus area as described above.
Braking with anti-lock protection
&
WARNING Risk of accident as a result of
locked brakes
The wheels of the trailer/semitrailer may lock
when braking and the tractor/trailer combi‐
nation may become unstable if:
R
the trailer/semitrailer does not have ABS
R
ABS of the trailer/semitrailer has failed
R
ABS has failed completely
As a result, you could lose control of the trac‐
tor/trailer combination and cause an acci‐
dent.
#
Always adapt your driving style to the
prevailing road and weather conditions
and maintain a sufficient, safe distance
from other road users.
#
Avoid maximum full-stop braking except
in emergency situations.
%
Even if Stability Control Assist is activated
the wheels of the trailer/semitrailer can still
lock when braking.
Anti-lock protection improves the directional sta‐
bility and the steerability of the vehicle or trac‐
tor/trailer combination during braking.
If ABS is deactivated or if there is a malfunction
in the vehicle's brake system, Active Brake Assist
is automatically deactivated.
#
When ABS is intervening: continue to
depress the brake pedal until the braking sit‐
uation is over.
When ABS is intervening, the continuous
brake is switched off. The
Ã
indicator
lamp in the instrument cluster remains on.
#
During maximum full-stop braking:
depress the brake pedal with force.
Under certain conditions, the hazard warning
lights switch on automatically.
If you want to drive the towing vehicle with a
trailer/semitrailer with ABS or an electronic
brake system:
#
Connect a control cable to the socket or to
the ABS plug (
/
page 290).
If you want to drive the semitrailer truck without
a semitrailer or with a semitrailer without ABS:
#
Insert the control cable into the blank socket.
Deactivating/activating ABS
&
WARNING Risk of skidding when ABS is
deactivated
If ABS is deactivated, the wheels may lock
when braked.
As a result, the vehicle can no longer be
steered.
#
Always leave ABS on when driving on
roads and firm surfaces.
ABS is automatically activated when you start the
engine.
If ABS is deactivated, it may be possible to ach‐
ieve shorter braking distances when driving off-
road or on unpaved roads, e.g. on soft ground.
Only ABS on the towing vehicle can be deactiva‐
ted.
