to stabilize the vehicle/trailer combination in
this situation.
ESP
®
trailer stabilization is activated above
speeds of about
40 mph (65 km/h).
If ESP ®
is switched off or deactivated because
of a malfunction, the trailer stabilization sys-
tem will not function.
Crosswind Assist Observe the important safety guidelines for
the driving safety system (Y page

66).
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
automatically. ESP ®
intervenes with stabilizing
braking 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 mes-
sage.
Crosswind Assist is activated automatically
above a vehicle speed of approx. 50 mph
(80 km/h) when the vehicle is driving straight
ahead or cornering gently.
Crosswind Assist does not react in the follow-
ing situations:
R in the event of severe jolts and vibrations,
e.g. when driving over uneven surfaces or
potholes
R when road adhesion is reduced, e.g. on
snow or ice or when hydroplaning
Crosswind Assist does not work if ESP ®
is
deactivated or disabled because of a malfunc-
tion. Theft deterrent locking system
