Fu nctions of ABS (anti-lock braking sy st em)
ABS re gulates th e brake pressure in critical driv‐
ing situations: R
During braking, e.g. at maximum full-s to p
braking or insuf fi cient traction of th e tires,
th e wheels are pr ev ented from blocking.R
Ve hicle st eerability while braking is ensured.
If ABS inter ve nes when braking, yo u will fe el a
pulsing in th e brake pedal. The pulsating brake
pedal can be an indication of hazardous ro ad
conditions and can ser ve as a re minder to ta ke
ex tra care while driving.
Sy st em limitations R
ABS is active from speeds of appr ox . 5 mp h
(8 km/h). R
ABS may be impaired or may not function if a
malfunction has occur re d and th e ye l‐
low % ABS wa rn ing lamp lights up contin‐
uously in th e instrument clus te r af te r th e
engine is st ar te d. Fu nction of BA S (Brake Assist Sy st em)
q
WA RNING Risk of an accident caused by
a malfunction in BA S (Brake Assi st Sys‐
te m)
If BA S is malfunctioning, th e braking dis ta nce
in an emergency braking situation is
increased.

R
If th e sensors malfunction due to ot her ra dar
source inter fe re nce, fo r ex ample stro ng ra dar
re fl ections in parking ga ra ge s.R
If a loss of tire pressure or a defective tire
has been de te cted and displ ay ed.
The sy st em may not re act cor re ctly:R
In compl ex traf fi c st ations where objects
cannot alw ay s be clearly identified.R
To pedestrians or ve hicles if th ey mo ve
qu ickly into th e sensor de te ction ra nge.R
To pedestrians who are hidden by ot her
objects. R
If th e typical outline of a pedestrian cann ot
be distinguished from th e bac kg ro und.R
If a pedestrian is not re cognized as su ch , e.g.
due to special clo th ing or ot her objects.R
On bends with a tight ra dius. Setting Ac tive Brake Assi st
Multimedia sy st em:

If a course-cor re cting brake application occu rs ,
th e re d wa rn ing lamp fl ashes in th e outside mir‐
ro r and a wa rn ing to ne sounds. In addition, a dis‐
pl ay 1 indicating th e danger of a side collision
appears in th e multifunction displa y.
In ra re cases, th e sy st em may make an inappro‐
priate brake application. This brake application
may be inter ru pte d at any time if yo u st eer
slightly in th e opposite direction or accelera te .
Sy st em limitations
Either a course-cor re cting brake application
appropria te to th e driving situation, or none at
all, may occur in th e fo llowing situations:R
Ve hicles or obs ta cles, e.g. crash ba rr iers, are
located on bo th sides of yo ur ve hicle.R
A ve hicle approaches to o closely on th e side.R
Yo u ha ve adop te d a sporty driving st yl e with
high cornering speeds. R

ing wheel in th e fo llowing circums ta nces:R
Ac tive Lane Ke eping Assist de te cts lane
markings. R
A front wheel passes ov er th e lane markings.
Whe th er a wa rn ing is issued and when th is
occurs also depends on th e selected sensitivity
setting (s ta nda rd or adaptive).
If yo u fa il to adapt yo ur drivin g st yl e, Ac tive Lane
Ke eping Assist can neither re duce th e ri sk of an
accident nor ove rr ide th e la ws of ph ys ics. It can‐
not ta ke into account ro ad, we ather or traf fi c
conditions. Ac tive Lane Ke eping Assist is only an
aid. Yo u are re sponsible fo r th e dis ta nce to th e
ve hicle in front, fo r ve hicle speed, fo r braking in
good time and fo r st ay ing in lane.
Ve hicles with Lane Tr acking pac ka ge : If th e
lane markings are solid lines and yo u do not
re act to th e wa rn ing, a lane-cor re cting brake
application can bring th e ve hicle back into th e
original lane.
Ve hicles with Driving Assistance pac ka ge or
Driving Assistance Plus pa ck age: If yo u do not re act to th e wa rn ing, a lane-cor re cting brake
application can bring th e ve hicle back into th e
original lane. In th e case of a broken lane mark‐
ing being de te cted, a brake application will only
be made if a ve hicle has been de te cte d in th e
adj
acent lane. Oncoming ve hicles, ove rt aking
ve hicles and ve hicles in adjacent lanes can be
de te cted.
The brake application is av ailable in th e speed
ra nge between 40 mp h (60 km/h) and 12 0 mp h
(200 km/h).
If a lane-cor re cting brake application occu rs , dis‐
play 1 appears in th e multifunction displa y. Sy st em limitations
No lane-cor re cting brake application occu rs in
th e fo llowing situations: R

If a loss of tire pressure or a defective tire
has been de te cted and displ ay ed.
The sy st em may be impaired or may not function
in th e fo llowing situations: R
There is poor visibilit y, e.g. due to insuf fi cient
illumination of th e ro ad, high ly va ri able shade
conditions, or due to ra in, sno w, fo g or heavy

outside te mp eratures down to -4 °F (-20 °C).
q
WA RNING Risk of accident when using
tire sealant.
In th e fo llowing situations, th e tire sealant is
unable to pr ov ide suf fi cient breakdown assis‐
ta nce, as it is unable to seal th e tire proper ly :R
There are cuts or punctures in th e tire

Yo u ha ve driven at a ve ry low tire pres‐
sure or on a fl at tire.

No ise or unusual handling ch aracteristics
While driving, pay attention to vibrations, noises
and unusual handling ch aracteristics, e.g. pulling
to one side. This may indicate th at th e wheels or
tires are damaged. If yo u suspect th at a tire is
defective, re duce yo ur speed immediatel y. St op
th e ve hicle as soon as possible to ch eck th e
wheels and tires fo r dama ge . Hidden tire dam‐
age could also be causing th e unusual handling
ch aracteristics. If yo u fi nd no signs of damage,
ha ve th e tires and wheels ch ec ke d at a qu alified
specialist wo rk shop.

q
WA RNING Risk of accident from dam‐
aged tires
Dama ge d tires can cause tire pressure loss.
As a re sult, yo u could lose cont ro l of yo ur

WA RNING Risk of accident caused by
re peated drop in tire pressure
If th e tire pressure drops re peatedl y, th e
wheel, va lv e or tire may be damaged.
Insuf fi cient tire pressure can cause th e tires
