If you deactivate ESP®
:
R ESP ®
no longer improves driving stability.
R the engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
If ESP ®
is deactivated and one or more wheels
start to spin, the d warning lamp in the
instrument cluster flashes. In such situations,
ESP ®
will not stabilize the vehicle.XTo deactivate: press button :.
The d warning lamp in the instrument
cluster lights up.GWarning
When the d ESP®
warning lamp is
illuminated continuously, the ESP ®
is
switched off or is not operational due to a
malfunction. Vehicle stability in standard
driving maneuvers is reduced.
Adapt your speed and driving style to the
prevailing road conditions and to the non-
operating status of the ESP ®
.
! Avoid spinning a drive wheel for an
extended period with ESP switched off. This
could cause serious damage to the drive
train.
XTo activate: press button :.
The d warning lamp in the instrument
cluster goes out.Off-road ESP ®
An ESP
®
system specifically suited to off-road
terrain is activated automatically if the off-
road drive program is activated
( Y page 204)or if the LOW RANGE off-road
gear ( Y page 157) is selected. It intervenes
with a delay if there is oversteering or
understeering, thus improving traction.
ESP ®
trailer stabilization
If your trailer begins to lurch, you can only
stabilize the vehicle/trailer combination by
depressing the brake firmly.
In this situation, ESP ®
assists you and can
detect if the trailer begins to lurch. ESP ®
slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilized.
Trailer stabilization is active from a speed
above 40 mph (65 km/h).
GWarning!
The system will not be able to assist when the
trailer jackknifes
R if the ESP ®
has switched off due to a
malfunction
R on wet or icy roads
R on roads with slippery surface
R in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying of
the trailer.
Trailer stabilization does not work if ESP ®
is
deactivated or disabled because of a
malfunction.
