Off-road ABS
An AB
Ssystem specifically suited to off -road
ter rain is activated automatically once th eoff-
road program (Y page 222) is activated.
At speeds below 30 km/h, the front wheels
loc kc yclically durin gbraking .The digging-in
eff ect ac hieved in the process red ucesthe
stopping distanc eonoff-road terrain. This
limits steering capability. BAS (Brak
eAssist)
i Observ ethe "Importan tsafety notes" sec-
tion (Y page 61).
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usua lonce you
releas ethe brake pedal. BA Sisd eactivated. G
WARNING
If BAS has malfunctioned, the braking system
remains available with ful lbrake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and th estopping distance may
increase. BAS PLU
S(Brak eAssist System Plus)
BA SP LUS is only availabl eonvehicles with
DI ST RONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 61).
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor syste mtoevaluate
the traffic situation.
With the hel pofthe radar sensor system ,BAS
PLUS can detect obstacles that are in the path of your vehicl
efor an exte nded period of
time.
At speeds up to approximately 70 km/h ,BAS
PLUS may also detect stationary obstacles,
for example ,stopped or parked vehicles.
Shoul dyou approach an obstacle and BAS
PLU Shas detected arisk of collision, BAS
PLU Scalculates the braking force necessary
to avoid arear-end collision .Should you apply
the brakes forcefully ,BAS PLUS can auto-
matically increase the braking force to alevel
suitabl efor the traffic conditions.
If BA SPLUS demand sparticularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
)a re activate dsimul-
taneously.
X Keep the brake pedal depressed until the
emergenc ybraking situatio nisover.
ABS prevent sthe wheels from locking.
The brakes will wor knormally again if:
R you release the brake pedal.
R ther eisnol onger any danger of arear-end
collision.
R no obstacl eisdetected in front of your
vehicle.
BAS PLU Sisthen deactivated .Ifyou have
activated DSR (Y page 220), BASPLUS is

passenger protection measures (PRE-SAFE ®
)
are activated (Y page 45). If the risk of colli-
sion remains and you do not brake, take eva-
