A rain sensor automatically controls the
windshield wipers depending on how wet
the windshield is.
Switch on ignition.

iIntermittent wiping is interrupted when
the vehicle is at a standstill and a door
is opened.
!Do not leave windshield wipers in inter-
mittent setting when vehicle is taken to
an automatic car wash or during wind-
shield cleaning. Wipers will operate in
the presence of water sprayed on the
windshield, and wipers may be dam-
aged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and/or damage the wiper blades
when wiping occurs on a dry wind-
shield.

Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:
Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed
ABC with vehicle level control systems,
with which you can change vehicle sus-
pension characteristics
Parktronic*, which assists the driver
during parking maneuvers
For information on the BAS, ABS, and ESP,
see “Driving safety systems” (
page 75).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 20).
Warning!
G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always re-
main responsible for the vehicle speed and
for safe brake operation.
Only use the cruise control if the road,
traffic, and weather conditions make it ad-
visable to travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate the cruise control when driv-
ing in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
Page 197 of 434

196 Controls in detailDriving systemsDistronic*
When activated, the Distronic adaptive
cruise control system increases the driving
convenience afforded by the cruise control
during travel on expressways and other
major roads.
If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle speed will be reduced so
that you follow that vehicle at a preset
distance.
If there is no vehicle directly ahead of
you, Distronic will function in the same
way as cruise control (
page 193).
Warning!
G
Distronic adaptive cruise control is no sub-
stitute for active driving involvement. It does
not react to stationary objects, nor recog-
nize or predict the curvature and lane layout
or the movement of vehicles ahead. Distron-
ic can only apply a maximum of 20% of the
vehicle’s braking power.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle.Warning!
G
Distronic is a convenience system, its speed
adjustment reduction capability is intended
to make cruise control more effective and
usable when traffic speeds vary. It is not
however, intended to, nor does it, replace
the need for extreme care. The responsibili-
ty for the vehicle speed and the distance to
the vehicle ahead, including most impor-
tantly brake operation to assure safe stop-
ping distance, always rests with the driver.
Distronic cannot take street and traffic con-
ditions into account.
Warning!
G
Distronic requires familiarity with its opera-
tional characteristics. We strongly recom-
mend that you review the following
information carefully before operating the
system.iFor operation in the USA only: This de-
vice complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions:
This device may not cause harmful
interference.
and
This device must accept any inter-
