Driving and pa rking

If a course-correcting brake application occurs ,
th ere dwa rning lamp flashes in the outside mir‐
ro r and a warning tone sounds. In addition, a dis‐
pl ay 1 indicating the danger of a side collision
appears in the multifunction displa y.
In rare cases, the sy stem may make an inappro‐
priate brake application. This brake application
may be inter rupte d at any time if yousteer
slightly in the opposite direction or accelera te.
Sy stem limitations
Either a course-cor recting brake application
appropria teto the driving situation, or none at
all, may occur in thefo llowing situations:
RVe hicles or obs tacles, e.g. crash barr iers, are
located on bo thsides of your vehicle.
RAve hicle approaches too closely on the side.
RYo u ha veadop ted a sporty driving style with
high cornering speeds.
RYo ubr ake or accelerate signif icantly.

Driving and pa rking

You are warned byvibration pulses in thesteer‐
ing wheel in thefo llowing circums tances:
RAc tive Lane Keeping Assist de tects lane
markings.
RA front wheel passes over the lane markings.
Whe ther a warning is issued and when this
occurs also depends on the selected sensitivity
setting (s tanda rdor adaptive).
If yo ufa ilto adapt your drivin gst yle, Ac tive Lane
Ke eping Assist can neither reduce therisk of an
accident nor override the la wsof ph ysics. It can‐
not take into account road, weather or traf fic
conditions. Active Lane Keeping Assist is only an
aid. You are responsible forth e dis tance tothe
ve hicle in front, forve hicle speed, for braking in
good time and forst ay ing in lane.
Ve hicles with Lane Tracking pac kage:If th e
lane markings are solid lines and youdo not
re act tothewa rning, a lane-cor recting brake
application can bring theve hicle back into the
original lane.
Ve hicles with Driving Assistance pac kage or
Driving Assistance Plus pa ckage: Ifyo udo not re
act tothewa rning, a lane-cor recting brake
application can bring theve hicle back into the
original lane. In the case of a broken lane mark‐
ing being de tected, a brake application will only
be made if a vehicle has been de tected in
the
adjacent lane. Oncoming vehicles, overtaking
ve hicles and vehicles in adjacent lanes can be
de tected.
The brake application is available in the speed
ra nge between 40 mph (60 km/h) and 120mp h
(200 km/h).
If a lane-cor recting brake application occurs , dis‐
play 1appears in the multifunction displa y.Sy

ties)
& WARNING Risk of accident when driving
in li mp-home mode
When driving in emergency mode the han‐
dling characteristics are impaired, e.g. when
cornering, when accelerating stronglyand
when braking.
#Do not exceed the specified maximum
speed.
#Av oid any abrupt steering and driving
maneuvers as well as driving over
obs tacles (curbs, pot holes, off-road).
This applies, in part icular,toa loaded
ve hicle.
#Stop driving in the emer gency mode if
yo u notice:
Rbanging noise
Rvehicle vibration
Rsmoke which smells like rubber
Rcontinuous ESP®inter vention
Rcrac ksin tire side walls
#After driving in emergency mode ha ve
th erims checkedby aqu alified special‐
ist workshop with rega rd totheir fur ther
use.
#The defective tire must be replaced in
eve rycase.
With MOExtended tires (run-flat tires), you can
continue todrive your vehicle even if there is a
tot al loss of pressure in one or more tires. How‐
eve r,th e tire af fected must not show any clearly
visible damage.
Yo u can recognize MOExtended tires bythe
MOExtended marking which appears onthe side
wa ll of the tire.
Ve hicles with tire pressure monitoring sys‐
te m: MOExtended tires may only be used in con‐
junction wi than activated tire pressure monitor‐
ing sy stem.
If a pressure loss warning message appears in
th e multifunction display:
RCheck the tire for dama ge.
