Functions of ESP
®
Crosswind Assist
Crosswind Assistdoes notreact under thefollow‐
ing conditions:
R
The vehicle is subjected to severe jolts and
vibrations, e.g.asaresult of unevensurfaces
or potholes.
R
The vehicle loses traction, e.g. on snoworice
or when hydroplaning.
R
The driver is performing sudden and large
steering movements.
Crosswind Assistisoperational again as soon as
thedriving conditions returntonormal.
Crosswind Assist detects strong crosswind gusts
that can impair abilityofyour vehicle to drive
straight ahead. CrosswindAssistintervenes
depending on thedirection and strengthofthe
crosswind.
Astabilizingbrake applicationhelps youtokeep
thevehicle on track.
Information is shown in theinstrument clusterin
theevent of aclearly discernible intervention by
Crosswind Assist.
Crosswind Assistisactiveabove avehicle speed
of 50 mph(80 km/h) when driving straight or
slightly cornering.

WARNING Risk of accident in poorroad
and weather conditions
In poor road and weather conditions, the
trailerstabilizationcannotprevent lurching of
thevehicle/trailer combination.Trailerswith
ahigh centerofgravity maytip overbefore
ESP

detects this.

ESP
®
trailer stabilizationcounteracts criticaldriv‐
ing situations in goodtime and therebyprovides
considerable assistance when driving with a
trailer. Trailer stabilizationispartofESP
®
.
If thesensor system and evaluationlogic detect
trailer swinging movements, ESP
®
trailer stabili‐
zation initiallybrakesindividual vehicle wheels in
atargetedmanner.Itthus counteracts swinging
movements. If theswinging movements do not
stop, thevehicle is braked until thevehicle/
trailer combination is stabilized. If necessary, the
vehicle's engine output is limited.
If your vehicle withtrailer (vehicle/trailer combi‐
nation) starts to swerve,you areable to stabilize
thevehicle/trailer combination onlybybraking.
ESP
®
trailer stabilizationhelps youtostabilize
thevehicle/trailer combination in this situation.
ESP
®
trailer stabilizationisactiveatspeeds
above approximately 40 mph(65 km/h).
If ESP
®
is deactivated because of amalfunction,
trailer stabilizationwill notfunction.
Function of EBD (electronic brakeforce distri‐
bution)
EBDhas thefollowing characteristics:
R
monitoring and controllingthe braking force
on therear wheels
R
improving driving stabilizationwhen braking,
especiallyonbends
Function of ActiveBrake Assist
ActiveBrake Assist consistsofthe following func‐
tions:
R
Distance warning function
R
Autonomous braking function
R
Situation-dependent braking assistance
ActiveBrake Assist can helpyou to minimize the
risk of acollision withvehicles or pedestrians or
to reduce theeffects of suchacollision.
If ActiveBrake Assist has detected arisk of colli‐
sion, youwill be warned visuallyand acoustically.
If youdonot react to thevisual or acoustic warn‐
ing, autonomous brakingcan be initiated in criti‐
cal situations.
If thereare pedestrians and cyclists crossing: in
especiallycritical situations, ActiveBrake Assist
can initiateautonomous braking directly. In this
case, thevisual and acoustic warning occurs
simultaneouslywiththe braking application.
If youapplythe brakeyourself in acritical situa‐
tion, or applythe brakes during autonomous
braking, situation-dependent braking assistance
occurs.The brakepressureincreases up to maxi‐
mum full-stopbraking if necessary. Situation-
dependent braking assistance only intervenes
when thebrakesare applied firmly;otherwise, it
remains within theautonomous braking process.
