WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il.
#Ne ver use the brake pedal as a foot re st.
#Do not depress the brake pedal and the
accelerator pedal at the same time
while driving.
* NO

#Do not depress the brake pedal contin‐
uously whilst driving.
#To use the braking ef fect of the engine,
shift toa lo werge ar in good time.

#Have the cause rectified immediately at
a qu alified specialist workshop.
Limited braking ef fect on salt-treate dro ads:
Rdue tosalt build-up on the brake discs and
brake lining, the braking dis tance can
increase conside rably or result in braking
only on one side.
Rmaintain a much greater dis tance totheve hi‐

To preve nt salt build-up:
Rbrake occasionally while paying attention to
th e tra ffic conditions.
Rcarefully depress the brake pedal at the end

Driving and pa rking

IfAc tive Brake Assi sthas de tected a risk of colli‐
sion, youwill be warned visually and acousti‐
cally.
If yo udo not react tothe visual or acoustic warn‐
ing, autonomous braking can be initiated in criti‐
cal situations.
In especially critical situations, Active Brake
Assi stcan initiate autonomous braking direct ly.
In this case, the visual and acoustic warning
occurs simultaneously with the braking applica‐
tion.
If yo uappl yth e brake yourself ina critical situa‐
tion or applyth e brake during autonomous brak‐
ing, situation-dependent braking assis tance
occurs . If necessary ,th is inc reases the brake

&WARNING Risk of an accident despite
Evasive Steering Assist
Evasive Steering Assist cannot always clearly
identify objects and complex traf fic situa‐

In addition, thesteering support of Evasive
St eering Assist is general lynot suff icientto

In such cases Evasive Steering Assist can:
Rgive an unnecessary warning or pr ovide

Rnot give awa rning or not pr ovide assis‐
ta nce
#Alw ays pay careful attention tothe traf‐

#Be ready tobrake and take evasive
action if necessar y.
#Preve ntthe assis tance byactively steer‐

#Drive at an appropriate speed if pedes‐
trians are close tothe path of your vehi‐

Sy stem limitations
Ac tive Brake Assi stmay be impai red or may not

Ac tive Steering Assist
Function of Active Steering Assist
Ac tive Steering Assist is only available for
ve hicles with the Driving Assistance Pack‐
age.
RAc tive Steering Assist is operational at
speeds up to130mp h(210 km/h) and helps yo
uto stay inthe center of the lane by
means of moderate steering inter ventions.
RIt uses theve hicle in front and the lane mark‐
ings as a refere nce depending on the driven
speed.
RAc tive Steering Assist requiresyou as the
driver, tokeep your hands on thesteering
wheel at all times so that you are able to
inter vene at any time tocor rect the course of
th eve hicle and keep it in lane.
RAc tive Steering Assist can be overridden at
any time bysteering theve hicle yourself.
RWhen the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
Sy stem limitations of Active Steering Assist
Ac tive Steering Assist has a limited steering tor‐
qu efo r lateral guidance. In some cases, the
st eering inter vention is not suff icienttokeep the
ve hicle in the lane.
If th e de tection of lane markings and vehicles
ahead is impaired, Active Steering Assist
switches topassive mode. The sy stem pr ovides
no support in this case. During the transition from
the active topassiv e
st at
us, theè sym‐
bol is shown as enlar ged and flashes yello w.
Once the sy stem is passive theè symbol is
shown as gr ayinthe multifunction displa y.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
RIfth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, or due tosno w,
ra in, fog or heavy spr ay.
RIfth ere is glare, e.g. from oncoming traf fic,
dire ct sunlight or reflection from other vehi‐
cles (e.g. if thero ad is wet).
RIfth e windshield is dirty, fogged up, damaged
or co vered, for ins tance byast icke r,in the
vicinity of the camera.
RIf no, or se veral, unclear lane markings are
present for one lane, e.g. in a construction
area.
RIf th e lane markings are wornaw ay, dark or
co vered up, e.g. bydirt or sno w.
RThe distance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.
