\nWARNINGRisk of skidding and of anaccident duetoshifting down on slipperyroad surfaces
Ifyou shift down on slipperyroad surfacestoincreasethe engine braking effect,the drivewheels may lose traction.
Do not shift down on slipperyroad sur‐facestoincreasethe engine brakingeffect.
Whenthe automatic transmission is shiftedtoposition[,you can manually shift it withthe
steering wheel paddle shifter.If permitted,theautomatic transmission shiftstothe nextgearup or down depending onthesteering wheelpaddle shifter being pulled.

Depending onthevehicle's equipment,theradarsensors are integrated behindthe bumpersand/or behindthe Mercedesstar.Keeptheseparts free of dirt, ice and slush(page 364). The sensors must not be cov‐ered,forexamplebycycleracks,overhangingloads,stickers,foil orfoilstoprotect againststonechipping.

RFully depressingthe accelerator pedal orwith kickdown.
RReleasingthe brake pedal.
Active Brake Assistmay cancelthe brake appli‐cation when one ofthefollowing conditions isfulfilled:
RYou maneuvertoavoidthe obstacle.
RThereis no longer arisk of collision.
RAn obstacle is no longer detected in front ofyourvehicle.

RReaction from a speed of approximately12mph (20 km/h) uptoa speed of approx‐imately 43mph (70 km/h).
You can preventthe assistance at any timebyactivelysteering.
\nWARNINGRisk of an accident despiteEvasiveSteering Assist
EvasiveSteering Assist cannotalways clearlyidentify objects and complex traffic situa‐tions.
In addition,thesteering support of EvasiveSteering Assist isgenerally not 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.
System limitationsFull system performance is notavailablefor afew seconds after switching onthe ignition orafter driving off.
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 are impaired duetointerfer‐ence fromotherradar sources, e.g.strongradarreflections in parkinggarages.
RIf a loss of tire pressure or a defective tirehas been detected and displayed.
RIn complex traffic situations whereobjectscannotalways be clearly identified.
RIf pedestrians orvehicles movequickly intothe sensor detectionrange.
RIf pedestrians are hiddenby other objects.
RIfthe typical outline of a pedestrian cannotbe distinguished fromthe background.
RIf a pedestrian is not detected as such, e.g.duetospecial clothing orother objects.
ROn bends with a tightradius.
