RYou haveadopted a sporty drivingstyle withhigh cornering speeds or highrates of accel‐eration.
RWhen ESP®is deactivated.
RIf a loss of tire pressure or afaulty tire hasbeen detected and displayed.
The system may be impaired or may not functioninthefollowing situations:
RIfthere is poor visibility, e.g. duetoinsuffi‐cient illumination oftheroad, ifthere arehighlyvariable shade conditions or inrain,snow,fog or heavy spray.
RIfthere isglare, e.g. from oncoming traffic,the sun orreflections.
RIfthe windshield inthe area ofthe multifunc‐tion camera is dirty, or ifthe camera isfog‐ged up, damaged or covered.
RIfthere are no lane markings, or severalunclear lane markings are presentfor onelane, e.g. aroundroadworks.
RIfthe lane markings areworn, dark or cov‐ered.
RIfthe distancetothevehicle in front istooshort andthusthe lane markings cannotbedetected.
RIfthe lane markingschangequickly,e.g.lanes branch off, cross one another ormerge.
RIftheroadwayisverynarrow and winding.
Vehicles with Driving Assistance packageorDriving Assistance Plus package:Active LaneKeeping Assist usesradar sensorstomonitorseveral areas aroundthevehicle. Iftheradarsensors intherear bumper are dirty or coveredwith snow,the system may be impaired or maynot function. If an obstacle inthe lane in whichyou are driving has been detected, no lane-cor‐recting brake application occurs.

\nWARNINGRisk of accident despiteActive LaneKeeping Assistwarning
A lane-correcting brake application cannotalwaysbringthevehicle back intothe origi‐nal lane.
Alwayssteer, brake or accelerateyour‐self, especially ifActive LaneKeepingAssistwarnsyou or makes a lane-cor‐recting brake application.
\nWARNINGRisk of accident despiteinter‐vention ofActive LaneKeeping Assist
Active LaneKeeping Assist does not detecttraffic conditions orroad users. Inveryrarecases,the system may make an inappropri‐ate brake application, e.g. after intentionallydrivingover a solid lane marking.
The brake application can be interrupted atany time ifyousteer slightly inthe oppositedirection.

Always make surethatthere is suffi‐cient distancetothe sideforother traf‐fic or obstacles.
\nWARNINGRisk of accident despiteLaneKeeping Assist
LaneKeeping Assist cannotalways clearlydetect lane markings.
In suchcases, LaneKeeping Assist can:
Rgive an unnecessarywarning
Rnot give awarning
Always pay particular attentiontothetraffic situation andkeep withinthelane, especially ifActive LaneKeepingAssist alertsyou.
Be suretoobservethe system limitations ofActive LaneKeeping Assist.

Notes onstarting assistance and oncharg‐ingthe12V battery
Vehicles with a lithium-ion batteryWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
NOTEDamagetothe battery fromover‐voltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthe on-board electronics may be damaged.
Only use batterychargerswith a maxi‐mumchargingvoltage of14.4V.
AllothervehiclesWhenchargingthe battery and duringstartingassistance, alwaysusethe jump-startconnec‐tion point inthe engine compartment.
NOTEDamagingthe batterythroughovervoltage
Whencharging using a batterycharger with‐out a maximumchargingvoltage,the batteryorthevehicle electronics may be damaged.
Only use batterychargerswith a maxi‐mumchargingvoltage of14.8V.
\nWARNINGRisk ofexplosion fromhydro‐gengas igniting
A batterygenerateshydrogengas duringthecharging process. Ifthere is a short circuit orsparksstarttoform,there is a danger ofthehydrogengas igniting.
Make surethatthe positiveterminal ofthe connected battery does not comeinto contact withvehicle parts.
Never place metal objects ortools on abattery.
When connecting and disconnectingthebattery,you must observethe descri‐bed orderforthe battery clamps.
372Breakdown assistance

When givingstarting assistance, alwaysmake surethatyou onlyconnect bat‐teryterminals with identical polarity.
Duringstarting assistance,you mustobservethe described orderfor con‐necting and disconnectingthe jumpercables.
Do not connect or disconnectthe bat‐teryclamps whilethe engine isrunning.
\nWARNINGRisk ofexplosion duringcharging process andstarting assistance
Duringthecharging process andstartingassistance,the battery mayrelease anexplo‐sivegas mixture.
Avoidfire, openflames, creating sparksand smoking.
Make surethatthere is sufficientventi‐lation duringthecharging process andduringstarting assistance.
Do not leanover a battery.
\nWARNINGRisk ofexplosion from a fro‐zen battery
A discharged battery may freeze attempera‐tures slightly aboveor below freezing point.
Duringstarting assistance or batterycharg‐ing, batterygas may bereleased.
Alwaysthawa frozen batteryoutfirstbeforecharging it or performingstart‐ing assistance.
Ifthe indicator/warning lamps inthe instrumentcluster do not light up at lowtemperatures, it isverylikelythatthe discharged battery has fro‐zen. Inthis caseyou may neither jump-startthevehicle norchargethe battery.
The service life of a batterythat has beenthawed may be dramatically shortened. Thestartingcharacteristics may be impaired, espe‐cially at lowtemperatures.
It isrecommendedthatyou haveathawed bat‐terychecked at aqualified specialistworkshop.
