Trailer stabilisation
Observe the important safety guidelines for the
driving safety system (Y page 70).
G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with a high centre of gravity can
tip over before ESP
®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
ESP
®
trailer stabilisation counteracts critical
driving situations in good time and thereby pro-
vides considerable assistance when driving with
a trailer. Trailer stabilisation is part of ESP
®
.
If the sensor system and evaluation logic detect
trailer swinging movements, ESP
®
trailer stabi-
lisation firstly brakes individual vehicle wheels in
a targeted manner. It thus counteracts swinging
movements. If the swinging movements do not
stop, the vehicle is braked until the vehicle/
trailer combination is stabilised. If necessary,
the vehicle's engine output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) starts to swerve, you will be able to
stabilise the vehicle/trailer combination only by
braking. ESP
®
trailer stabilisation helps you to
stabilise the vehicle/trailer combination in this
situation.
ESP
®
trailer stabilisation is active above speeds
of about 65 km/h.
If ESP
®
is switched off or deactivated because of
a malfunction, the trailer stabilisation system
will not function.
Crosswind Assist
Observe the important safety guidelines for the
driving safety system (Y page 70).
Strong crosswind gusts can impair the road-
holding of your vehicle when driving straight
ahead. The Crosswind Assist function integra-
ted in ESP
®
reduces these impairments.
Depending on the direction and intensity of the
side wind, Crosswind Assist intervenes auto-
matically. ESP
®
intervenes with stabilising brak-
ing to assist you in keeping the vehicle in the
lane. When Crosswind Assist intervenes, the
display shows the traffic sign for strong side
winds and the Crosswind Assist message.
Crosswind Assist is activated automatically
above a speed of approximately 80 km/h when
driving straight ahead or cornering gently.
Crosswind Assist does not react:
R
in the event of severe jolts and vibrations, e.g.
when driving over uneven surfaces or pot-
holes
R
when grip is reduced, e.g. on snow or ice or
when aquaplaning
Crosswind Assist does not work if ESP
®
is deac-
tivated or disabled because of a malfunction.
Adaptive brake lights
In an emergency braking situation, the adaptive
brake lights warn following traffic:
R
by flashing brake lamps
R
the hazard warning lamps are activated
If you brake sharply from a speed of more than
50 km/h or if braking is assisted by BAS, the
brake lamps flash rapidly.
If you brake sharply from a speed of more than
70 km/h to a standstill, the hazard warning
lamps are activated automatically. The brake
lamps light up again constantly when you
depress the brake pedal. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off the
hazard warning lamps with the hazard warning
lamp button (Y page 117).
