Child restraint system
The use of seat beltsand infant and child
restraint systems is required by law in:
Rall 50 states
Rth eU .S.t erri tories
RtheD istrict of Columbia
Rall Canadian provinces
You can obtain further informatio nabout the
correc tchild restraint system from any
Mercedes-Ben zCommercial Van Center.
GWARNING
If th echild restraint system is installed incor-
rectly on asuitable seat,itc annotprotect as
intended. The child canno tthe nber estrained
in th eevent of an accident, heavyb raking or
suddenc hanges of direction.T hereisan
increased ris kofinjury, possibly eve nfatal.
Makes ure that you observ ethe child restraint
system manufacturer'si nstallationinstruc-
tions and th enotes on use. Pleasee nsure,
that th ebase of th echild restraint system is
always restin gcompletely on th eseat cush-
ion.N ever placeo bjects, e.g.cushions, under
or behindt hechild restraint system. Only use
child restraint systems witht heoriginal cover
designe dfor them. Only replace damaged
covers withg enuine covers.
GWARNING
If ar earward facing child restraint system is
installed in th edirection of travel by mistake,
it canno tprotect as intended. This is th ecase
if, for instance, you install arearward-facing
child restraint system on arear seat opposite
to th edirection of travel. In th eevent of an
accident, achild migh tnotbe restraine dcor-
rectly. This posesani ncreased riskofinjury or
eve nfatal injury.
Always install th erear seat in th edirection of
travel before you install th erearward facing
child restraint system.
GWARNING
If th echild restraint system is installed incor-
rectly or is no tsecured, it can com eloosei n
th ee vent of an accident, heavyb raking or a

Always install child restraint systems prop-
erly, eve niftheya re no tbeingu sed. Make
sure that you observ ethe child restraint sys-

passenger seat as far back as possible.T he
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat. The child restraint system must not touch
the roof or be subjected to aload by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.

Overview
In thiss ection, yo uwillf indi nformation about
the following drivin gsafety systems:
REBD ( Ele ctronic Brake Force Distribution)
RABS ( Anti-lock Braking Sys tem)
RBAS ( Brake Assist System)

Important safety notes
If yo ufailtoa dapt your drivin gstyle or if yo uare

ABS (Anti-lock Braking System)
General notes
ABS regulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking.
The ò warning lamp in the instrument cluster
lights up when the ignition is switched on. The
lamp goes ou twhent he engine starts running.
Important safety notes
Observe the important safety guideline sfor the
drivin gsafety system(Ypage 62).
ABS works fromas peedof abou t5mph
(8 km/h), regardles sofroad-surface conditions.
ABS works on slippery surfaces ,evenw heny ou
onl ybrake gently.
GWARNING
If ABS is faulty, the wheels could lock when
braking .The steerability an dbraking charac-
teristics maybes everel yimpaired. Addition-
ally ,fur the rdrivin gsafety systems ar edeac-
tivated .Ther eisani ncreasedd angerofs kid-

If ABS is malfunctioning, theòwarning lamp
(Ypage 221) lights up whil ethe engine is run-
ning and the display shows amessage:
Ron vehiclesw ithoutsteering wheel buttons
(Ypage 189)
Ron vehiclesw ith steering wheel buttons
(Ypage 203)
BAS, Hill Start Assist and ESP®and its driving
safety systems and other driving systems also
fail .Observe the notes on the òwarning
lamp and the display messages.
Braking
If ABS intervenes when braking, you wil lfeel a
pulsating in the brake pedal.
The pulsating brake pedalc an be an indication
of hazardous road conditions and functions as a
reminder to take extra care whiled riving.
XIf ABS intervenes:continue to depresst he
brake pedalw ith force until the braking sit-
uatio niso ver.
XTo make afull brake application: depress
the brake pedalw ith full force.
BAS (Brake Assist System)
General notes
BAS operates in emergency braking situations.
If you depresst he brake pedalq uickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 62).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased .There is arisk of an accident.
In an emergency braking situation, depress
the brake pedalw ith full force. ABS prevents
the wheel sfrom locking.
If BAS is malfunctioning, the ÷warning lamp
lights up whil ethe engine is running
(
Ypage 221) and the display shows amessage:
Ron vehiclesw ithoutsteering wheel buttons
(Ypage 193)
Ron vehiclesw ith steering wheel buttons

Braking
XKeep the brake pedalf irmly depressed until
the emergency braking situation is over.
ABS prevents the wheel sfrom locking.
The brakes willf unction as usual once you
release the brake pedal. BAS is deactivated.
EBD (electroni cbrake force distribu-
tion)
General notes
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve handling during braking.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 62).
GWARNING
If EBD is malfunctioning, the rear wheelsc an
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You shoul dtherefore adapt you rdriving style
to the different handling characteristics. Have
the brake system checked at aqualifieds pe-
cialist workshop.
If EBD is malfunctioning, the $warning lamp
