Distronic
Safety notes
When activated, the Distronic adaptive cruise
control increases the driving convenience
afforded by the cruise control while traveling
on expressways and other major roadways.
R 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 your preset following
distance.
R If there is no vehicle directly ahead of you,
the Distronic will function in the same way
as standard cruise control ( Y page 130).
GWarning!
The Distronic requires familiarity with its
operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system.
GWarning!
The 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 responsibility for the vehicle’s speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The Distronic cannot take street and traffic
conditions into account. Complex driving
situations are not always fully recognized by
the Distronic. This could result in wrong or
missing distance warnings.GWarning!
The Distronic adaptive cruise control is not a
substitute for active driving involvement. It
does not react to pedestrians or on stationary
objects, nor does it recognize or predict the
lane curvature or the movement of preceding
vehicles.
The Distronic can only apply 20% of the
maximum braking power of the vehicle.
It is the driver’s responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide the steering, braking and other driving
inputs necessary to remain in control of the
vehicle.
High-frequency sources such as toll stations,
speed measuring systems etc. can cause the
Distronic system to malfunction.
GWarning!
The Distronic cannot take road and traffic
conditions into account. Only use the
Distronic if the road, weather and traffic
conditions make it advisable to travel at a
constant speed.
GWarning!
Use of the Distronic can be dangerous on
slippery roads. Rapid changes in tire traction
can result in wheel spin and loss of control.
The Distronic does not function in adverse
sight and distance conditions. Do not use the
Distronic during conditions of fog, heavy rain,
snow or sleet.

detect one too soon. This may cause your
vehicle to brake late or unexpectedly.
Offset driving
A vehicle traveling in your lane but offset from
your direct line of travel may not be detected
by the Distronic. There will be insufficient
distance to the preceding vehicle.
Lane changing
The Distronic has not yet detected the vehicle
changing lanes. There will be insufficient
distance to the lane-changing vehicle.
Narrow vehicles
Because of their narrow profile, the vehicles
traveling near the outer edges of the lane
have not yet been detected by the Distronic.
There will be insufficient distance to the
preceding vehicles.
Distance warning function
When the Distronic is deactivated, this
function will continue to warn you when
recognizing a stationary obstacle or a slower
vehicle moving in your vehicle’s path and the
danger of a collision exists:

maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal.GWarning!
The hill-start assist system is not designed to
function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
Always engage the parking brake in addition

The Parktronic system deactivates at speeds
above approximately 11 mph (18 km/h). At
lower speeds, the Parktronic system
activates again.
The Parktronic system also deactivates when
you shift the automatic transmission into
park position P or engage the parking brake.
The Parktronic system monitors the
surroundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
Example illustration, sensors in the front bumper
To function properly, sensors \000F must be free
of dirt, ice, snow and slush. Clean
sensors \000F regularly. Be careful not to
scratch or damage sensors \000F, see “Cleaning
the driving systems sensors” (Y page 218).
GWarning!
The Parktronic is a supplemental system. It is
not intended to, nor does it replace, the need
for extreme care. The responsibility during
parking and other critical maneuvers always
remains with the driver.
GWarning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
! Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts,
elevated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
During parking maneuvers, pay special
attention to objects located above or below
the height of the sensors (e.g. street curbs,
painted posts, or trailer hitches etc.). The
Parktronic system will not detect such
objects at close range and damage to your
vehicle or the object may result.
! Ultrasonic signals from outside sources
(e.g. truck air brakes, car wash, or
jackhammers) may impair the operation of
the Parktronic system.
