The distance warning function issues a warn-
ing at speeds:
R
of around 30 km/h or more, if, over several
seconds, the distance maintained to the
vehicle travelling in front is insufficient.
The
·
distance warning lamp then lights
up in the instrument cluster.
R
of around 7 km/h or more, if you rapidly
approach a vehicle in front. An intermit-
tent warning tone will then sound and the
·
distance warning lamp will light up
in the instrument cluster.
X
Brake immediately in order to increase the
distance from the vehicle in front.
or
X
Take evasive action provided it is safe to
do so.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obsta-
cles that are in the path of your vehicle for an
extended period of time.
Up to a speed of around 70 km/h, the distance
warning function can also react to stationary
obstacles, such as stopped or parked vehi-
cles.
ESP
®
(Electronic Stability Program)
General notes
i
Observe the "Important safety notes" sec-
tion ( Y page 51).
esp
®
monitors driving stability and traction,
i.e. power transmission between the tyres and
the road surface.
If esp
®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. The engine output is also modified
to keep the vehicle on the desired course
within physical limits. esp
®
assists the
driver when pulling away on wet or slippery
roads. esp
®
can also stabilise the vehicle
during braking.
ETS (Electronic Traction System)
i
Observe the "Important safety notes" sec-
tion (
Y
page 51).
ETS traction control is part of esp
®
.
ETS brakes the drive wheels individually if
they spin. This enables you to pull away and
accelerate on slippery surfaces, for example
if the road surface is slippery on one side. In
addition, more drive torque is transferred to
the wheel with traction.
Important safety notes
G
WARNING
If ESP
®
is malfunctioning, ESP
®
is unable to
stabilise the vehicle. In addition, other
driving safety systems are switched off.
This increases the risk of skidding and an
accident.
Drive on carefully. Have ESP
®
checked at a
qualified specialist workshop.
!
If you test the parking brake using a brake
dynamometer, switch the ignition off.
Application of the brakes by ESP
®
may oth-
erwise destroy the brake system.
Observe the notes on esp
®
when towing away
your vehicle with the rear axle raised
(
