GWARNING
If yo uleave animals unattended or unsecured

As aresult, theyc ould:
Ractivate vehicl eequipment and become

Ractivate or deactivate systems, thereby
endangering othe rroa du sers
Unsecured animals could also be flung around

Driving safety systems
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)
RESP®(E le ctronic Stability Program)
Important safety notes
If yo ufailtoa dapt your drivin gstyle or if yo uare
inattentive, the drivin gsafety systems can nei-
therr educe the ris kofaccident nor override the
laws of physics .Drivin gsafety systems are
merel yaidsd esig nedtoa ssistdriving. Yo uare
responsibl efor the distance to the vehicl ein
front, for vehicl espeed, braking in good time
and for staying in your lane. Alway sadapt your drivin

tance fromo therroa du sers.D rive carefully.

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-
ding and accidents.
Drive on carefully. Hav eABS checked imme-
diately at aquali fied specialis tworkshop.

Safety

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
(Ypage 207)
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

ning and the display shows amessage.

If you fail to adapt yourdriving style, Lane Keep-
ing Assist can neither reduce the risk of accident
nor override the law sofphysics. Lane Keeping
Assist cannot take into account road, weather or
traffic conditions. Lane Keeping Assist is only an aid .You are responsible for the distance to the
vehicle in front, for vehicle speed,b raking in
good time and for staying in you rlane.
Lane Keeping Assist does not keep you rvehicle
in its lane.
The system may be impaired or may not function
if:
Rthere is poor visibility, e.g. due to insufficient
illuminatio nofthe road, or due to snow, rain,
fog or spray
Rthere is glare ,e.g. from oncoming traffic, the
sun or reflection from other vehicles( e.g. if
the road surface is wet)
Rthe windshield is dirty, fogged up, damaged or
covered, for instance by asticker, in the vicin-
ity of the camera
Rno, or several ,unclea rlane markings are pres-
ent for one lane, e.g. in aconstruction area
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
