Crosswind driving assistance
General information
Vehicles with MAGIC BODY CONTROL:
information on stabilizing the vehicle in the
event of crosswind (
Y
page 213).
Strong crosswinds can cause your vehicle to
deviate from a straight course. The crosswind
driving assistance function integrated into
ESP ® significantly reduces these effects.
ESP ® intervenes automatically according to
the direction and intensity of the crosswinds
affecting your vehicle.
ESP stabilities the vehicle with braking
interventions to assist you in keeping the
vehicle in the lane.
Crosswind driving assistance is active at
vehicle speeds above 50 mph (80 km/h)
