Driving systems
Driving systems
The following driving systems are
explained on the following pages:

Cruise control and Distronic*, with
which the vehicle can maintain a preset
speed

Airmatic DC adjusts the vehicle sus-
pension characteristics automatically
and controls the vehicle level

Parktronic system*, which assists the
driver during parking maneuvers
For information on the BAS, ABS, ESP
® and
EBP, see “Driving safety systems”
(
page 89).
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 above 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 on the left-hand side of the steering
column (
page 24).
Warning!G
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s 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.

Cruise control is activated.
The selected speed appears in the multi-
function display for approximately
5 seconds, and the corresponding speed-
ometer segments from the selected speed
to the vehicle maximum speed are illumi-

Warning!G
The cruise control brakes automatically so
that the set speed is not exceeded.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
iOn uphill or downhill grades, the cruise con-
trol may not be able to maintain the set speed.
Once the grade eases, the set speed will be re-
sumed.
On downhill grades, the cruise control maintains
the set speed with active braking action. In addi-
tion, on longer downhill grades the automatic
transmission will automatically downshift.

Canceling cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.
The cruise control is canceled. The last
speed set is stored for later use.
or
Briefly push the cruise control lever in
direction of arrow3 (
page 214).
The cruise control is canceled. The last
speed set is stored for later use.Setting a higher speed
Lift the cruise control lever in direction
of arrow1 (
page 214) and hold it
up until the desired speed is reached.
Release the cruise control lever.
The new speed is set.
iThe last stored speed is canceled when you
turn off the engine.
iThe cruise control automatically switches
off, if

you step on the brake pedal.

In this case the segments in the multifunc-
tion display (
page 139) go out and no
warning sounds.

the vehicle speed is below 20 mph
(30 km/h).

the ESP® switch (page 94).

you move the gear selector lever to position
N while driving.
The segments in the multifunction display
(
page 139) go out, and an acoustic warning
sounds.
!Moving the gear selector lever to positionN
while driving also cancels the cruise control.
However, the gear selector lever should not be
moved to positionN while driving except to
coast when the vehicle is in danger of skidding
(e.g. on icy roads).
iDepressing the accelerator pedal does not
deactivate the cruise control. After brief acceler-
ation (e.g. for passing), the cruise control will re-
sume the last speed set.
Warning!G
If you increase the vehicle set speed, keep in
mind that it may take a brief moment until
the vehicle has reached the set speed.
Increase the vehicle set speed to a value
that the prevailing road conditions and legal
speed limits permit. Otherwise, sudden and
unexpected acceleration of the vehicle
could cause an accident and/or serious in-
jury to you and others.

mind that it may take a brief moment until
the vehicle has reached the set speed.
Increase the vehicle set speed to a value
that the prevailing road conditions and legal
speed limits permit. Otherwise, sudden and
unexpected acceleration of the vehicle
could cause an accident and/or serious in-
jury to you and others.
iWhen you use the cruise control lever to de-
celerate, the brake system will automatically
brake the vehicle if the engine’s braking power
does not brake the vehicle sufficiently.
Warning!G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.

Driving systems
Distronic*
When activated, the Distronic adaptive
cruise control system increases 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 214).
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.
Distronic 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, traffic, and weather
conditions and to provide the steering, brak-
ing and other driving inputs necessary to re-
tain 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 remains 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.
iUSA only: This device has been approved by
the FCC as a “Vehicular Radar System”. The ra-
dar sensor is intended for use in an automotive
radar system only. Removal, tampering, or alter-
ing of the device will void any warranties, and is
not permitted by the FCC. Do not tamper with,
alter, or use in any non-approved way.
Any unauthorized modification to this device
could void the user’s authority to operate the
equipment.

If Distronic is activated, one or two seg-
ments come on around the set speed.
Warning!G
Close attention to road and traffic condi-
tions is imperative at all times, regardless of
whether or not Distronic is activated.
Use of Distronic can be dangerous on wind-
ing roads or in heavy traffic because condi-
tions do not allow safe driving at a steady
speed.
Distronic will not react to stationary objects
in the roadway (e.g. a stopped vehicle in a
traffic jam or a disabled vehicle). Distronic
will also not respond to oncoming vehicles.
Switch off Distronic:

when changing from the left to the right
lane if vehicles are moving more slowly
in the left lane

when entering a turn lane or highway off
ramp

in complex driving situations, such as in
highway construction zones
In these situations, Distronic will continue to
maintain the set speed unless deactivated.
Distronic is designed and intended only to
maintain a set speed and keep a set dis-
tance from moving objects in front of it.
Warning!G
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.
iThe vehicle speed displayed on the speed-
ometer can briefly vary from the speed setting
on the Distronic system.
