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


Distance warning function* (only avail-
able with Distronic*), which warns of
stationary objects or slower moving ve-
hicles that you are closing in on too
quickly


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, ESP
®,
and the electro-hydraulic brake system,
see “Driving safety systems” (
page 87).
Cruise control
The cruise control automatically maintains
the speed you set for your vehicle.
The use of the cruise control is recom-
mended for driving at a constant speed for
extended periods of time.
You can set or resume the 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 constant speed.

The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a constant speed.


The use of the cruise control can be dan-
gerous 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.

Canceling the cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.
The cruise control is canceled. The last
set speed is stored for later use.
or

Briefly push the cruise control lever in
direction of arrow3.
The cruise control is canceled. The last
set speed is stored for later use.
i
The last stored speed is canceled when you
turn off the engine.
i
The cruise control switches off automatical-
ly when


you step on the brake pedal


you depress the parking brake pedal
The cruise control also switches off automatical-
ly when


the vehicle speed is below
20 mph (30 km/h) (
page 209)


the ESP
® is in operation or switched off with
the ESP® switch (
page 91)


you move the gear selector lever to
positionN while driving
An acoustic warning sounds and the message
CC Off
appears in the multifunction display for
approximately 5 seconds.
!
Moving the gear selector lever to positionN
while driving cancels the cruise control. Howev-
er, 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).
i
Depressing 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.

212 Controls in detailDriving systemsSetting a higher speed
Lift the cruise control in direction of
arrow1 (
page 210) and hold it
there until the desired speed is
reached.

Release the cruise control lever.
The new speed is set.
Setting a lower speed

Depress the cruise control in direction
of arrow2 (
page 210) and hold it
there until the desired speed is
reached.

Release the cruise control lever.
The new speed is set.Fine adjustment in 1 mph
(Canada: 1 km/h) increments
Faster

Briefly tip the cruise control lever in
direction of arrow1 (
page 210).
Slower

Briefly tip the cruise control lever in
direction of arrow2 (
page 210).Setting to last stored speed
(“Resume” function)

Briefly pull the cruise control lever in
direction of arrow4 (
page 210).
The cruise control resumes to the last
set speed or, if no speed is stored, it
will set and store the current speed.

Remove your foot from the accelerator
pedal.
The selected speed appears in the mul-
tifunction display.
i
When 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 set speed stored in memory should only
be set again if prevailing road conditions
permit. Possible acceleration or decelera-
tion differences arising from returning to the
preset speed could cause an accident
and/or serious injury to you and others.

213 Controls in detail
Driving systems
Distronic*
When activated, the Distronic adaptive
cruise control system increases the driving
convenience afforded by the cruise control
while traveling on expressways and other
major roadways.

If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle’s speed will be reduced so
that you follow that vehicle at the pre-
set following distance.


If there is no vehicle directly ahead of
you, Distronic will function in the same
way as standard cruise control
(page 209).
Warning!
G
Distronic adaptive cruise control is not a
substitute for active driving involvement. It
does not react to pedestrians or stationary
objects, recognize or predict the lane curva-
ture nor the movement of preceding
vehicles.
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 the road, weather and traffic
conditions. In addition, the driver must pro-
vide the steering, braking and other driving
inputs necessary to remain in 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’s speed, distance to the
preceding vehicle and, most importantly,
brake operation to assure a safe stopping
distance, always rests with the driver.
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.Warning!
G
Distronic cannot take street and traffic con-
ditions into account. Only use Distronic if
the road, weather and traffic conditions
make it advisable to travel at a constant
speed.
