WARNING Risk of accident in poor road
and weather conditions
In poor road and weather conditions, the
trailer stabilisation cannot pr event lu rching of
th eve hicle/trailer combination. Trailers with
a high centre of gr avity may tip over before
ESP ®
de tects this. #
Alw ays adapt your driving style to suit
th e cur rent road and weather condi‐
tions. When driving with a trailer, ESP
®
can stabilise
yo ur vehicle if the trailer begins toswer vefrom
side toside:
R ESP ®
trailer stabilisation is active abo ve
speeds of 65 km/h.
R Slight swerving is reduced bymeans of a tar‐
ge ted, individual brake application on one
side. R
Intheeve nt of se vere swerving, the drive
sy stem output is also reduced and all wheels
are braked.
ESP ®
trailer stabilisation may be impaired or
may not function if:
R The trailer is not connec ted cor rectly or is

Cruise control may be unable tomaintain the

Increase recuperation in good time on long and

yo u will make use of the electric mo tor's braking
ef fect to charge the high-voltage batter y.This
re lie vesth e load on the brake sy stem and pre‐ ve

Do not use cruise control in thefo llowing situa‐

R In traf fic situations whi chrequ ire frequent

R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the

Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for a short-term speed restriction,
e.g. in built-up areas
R Perm anen t:for a longer-term speed restric‐
tion, e.g. in winter tyre mode
Yo u can store any speed abo ve20 km/h up to
