Some driving and driving safe
ty systems use
cameras and sensors tomonitor the area in
front of, behind or next totheve hicle.
Ke ep the areas around the sensors and cameras
free of dirt, ice or slush (/ page 299). The cam‐
eras and sensors must not be co vered, forex am‐
ple bybicycle rack s, overhanging loads, sticke rs,
fo il or foils toprotect against stone chipping.
Ad ditional licence plate brac kets can impair the
function of the ultrasonic sensors, in particular.
In theeve nt of damage or a severe impact in the
area of the sensors, ha vethe function of the
sensors checked at a qualified specialist work‐
shop. Ha vedamage or stone chipping in the area
of the cameras repaired at a qualified specialist
wo rkshop. If the sensors or cameras are dam‐
aged, some driving sy stems and driving saf ety
sy stems may no longer function proper ly.Overview of driving sy

nction of ABS The Anti-lock Brake Sy
stem (ABS) regulates the
brake pressure in critical driving situations:
R During braking, e.g. at full brake application
or insuf ficient tyre traction, the wheels are
pr eve nted from lock ing.
R Vehicle steerability while braking is ensured.
If ABS inter venes when braking, you will feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road
conditions and can ser veas a reminder totake
ex tra care while driving. Fu
nction of BAS The Brake Assist Sy
stem (BAS) supports your
eme rgency braking situation with additional
brake forc e.
If yo u depress the brake pedal quickl y,BA S is
acti vated:
R BAS au tomatically boosts the brake pres‐
sure.
R BAS can sho rten the braking dis tance. 13 2

design speed or up tothe set winter tyre limit. Obser

Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular

Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed restrictions, e.g. in built-
up areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode.
The variable limiter is operated using the cor re‐
sponding steering wheel buttons. You can store any
road speed from 30 km/h to250 km/h or
up tothe set winter tyre limit. You can also per‐
fo rm settings while theve hicle is stationary if
th eve hicle has been star ted.
