\nWARNINGRisk of an accident despiteEvasiveSteering Assist
EvasiveSteering Assist cannotalways clearlyidentify objects and complex traffic situa‐tions.
In addition,thesteering support of EvasiveSteering Assist isgenerallynot sufficienttoavoid a collision.
In such cases EvasiveSteering Assist can:
Rgive an unnecessarywarning or provideassistance
Rnot giveawarning or not provide assis‐tance
Always pay careful attentiontothe traf‐fic situation; do notrely on EvasiveSteering Assist alone.
Bereadytobrake andtakeevasiveaction if necessary.
Preventthe assistancebyactivelysteer‐ing in non-critical driving situations.
Drive at an appropriate speed if pedes‐trians are closetothe path ofyourvehi‐cle.
Also observethe system limitations of EvasiveSteering Assist.
System limitations
The system may be impaired or may not functioninthefollowing situations:
RIn snow,rain,fog, heavy spray, ifthere isglare, in direct sunlight or ingreatlyvaryingambient light.
RIfthe sensors are dirty,fogged up, damagedor covered.
RIfthe sensors malfunction dueto otherradarsource interference,forexamplestrongradarreflections in parkinggarages.
RIf a loss of tire pressure or a defective tirehas been detected and displayed.
The system may notreact correctly:
RIn complextraffic situations whereobjectscannotalways be clearly identified.
RTopedestrians orvehicles iftheymovequickly intothe sensor detectionrange.
RTopedestrians who are hiddenby otherobjects.
RIfthe typical outline of a pedestrian cannotbe distinguished fromthe background.
RIf a pedestrian is notrecognized as such, e.g.duetospecial clothing orother objects.
ROn bends with a tightradius.

If a critical situation is detectedwhen driving off, a visual and acousticwarning isgiven indicatingthatthe driver must nowtakecontrol ofthevehicle. Thevehicle is not acceler‐ated any further.
Active Distance AssistDISTRONIC is only an aid.The driver isresponsibleforkeeping a safe dis‐tancetothevehicle in front,forvehicle speedandfor braking in good time.
System limitations
The system may be impaired or may not functioninthefollowing instances:
RIn snow,rain,fog, heavy spray, ifthere isglare, in direct sunlight or in greatlyvaryingambient light.
RThe windshield inthe area ofthe camera isdirty,fogged up, damaged or covered.
RIftheradar sensors are dirty or covered.
RIn parkinggarages or onroads withsteepuphill or downhill gradients.
RIfthere are narrowvehicles in front, such asbicycles or motorcycles.
In addition, on slipperyroads, braking or accel‐erating can cause one or several wheelstolosetraction andthevehicle couldthen skid.
Do not useActive Distance AssistDISTRONIC inthese situations.
\nWARNINGRisk of accident from acceler‐ation or brakingbyActive DistanceAssistDISTRONIC
Active Distance AssistDISTRONIC may accel‐erate or brake inthefollowing cases,forexample:

Takeinto accountthe traffic situationbefore calling upthestored speed.
\nWARNINGRisk of accident duetoinsuf‐ficient decelerationbyActive DistanceAssistDISTRONIC
Active Distance AssistDISTRONIC brakesyourvehicle with upto50% ofthe maximumpossible deceleration. Ifthis deceleration isnot sufficient,Active Distance AssistDISTRONIC alertsyou with a visual andacousticwarning.
Inthese cases, adjustyour speed andkeep a sufficient distance.

Parking AssistPARKTRONIC is onlyan aid. It isnot a substituteforyour attentiontothe sur‐roundings. Theresponsibilityfor safe maneuver‐ing and parkingremains withyou. Make surethatthere are no persons, animals or objects in
the maneuvering area while maneuvering andparking in/exiting parking spaces.
Inthestandard setting, an intermittentwarningtone sounds from a distance of approximately1.0ft(0.3 m)toan obstacle in front and approx‐imately 3.3ft(1.0 m)toan obstacle behind. Acontinuoustone sounds from a distance ofapproximately 0.7ft(0.2 m). UsingtheWarnearlysetting inthe multimedia system,thewarningtonesfor front and side impact protec‐tion can also be settosound at a greater dis‐tance of approximately 3.3ft(1.0 m)(→page196).
