214 Controls in detailDriving systemsWarning!
G
Use of Distronic can be dangerous on slip-
pery roads. Rapid changes in tire traction
can result in wheel spin and loss of control.
Distronic does not act upon adverse sight
distance conditions. Do not use Distronic
during conditions of fog, heavy rain, snow or
sleet.
Warning!
G
Distronic cannot take weather conditions
into account. Switch off Distronic or do not
switch it on if:

roads are slippery or covered with snow
or ice
The wheels could lose traction while
braking or accelerating and the vehicle
could skid.


the sensor is dirty or visibility is dimin-
ished due to snow, rain or fog for exam-
ple
The distance control system functional-
ity could be impaired.
Always pay attention to surrounding traffic
conditions even while Distronic is switched
on. Otherwise, you may not be able to recog-
nize dangerous situations until it is too late.
This could cause an accident in which you
and/or others could be injured.
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 constant
speed.
Distronic will not react to stationary objects
on the roadway (e.g. a stopped vehicle in a
traffic jam or a disabled vehicle). Distronic
will also not respond to oncoming vehicles.

Driving systems
Setting the following distance in
Distronic
You can set the specified following dis-
tance for Distronic by varying the time set-
ting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, Distronic calculates and sets
the required following distance to the pre-
ceding vehicle. The set distance will ap-
pear in the right multifunction display
(page 217).
The distance setting thumbwheel for the
time setting is located on the lower section
of the center console.1Thumbwheel for setting following
distanceIncreasing distance
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the preceding vehicle.

Turn thumbwheel1 towards ¯.
Decreasing distance
Decreasing the distance setting tells
Distronic to maintain a shorter following
distance to the preceding ahead.

Turn thumbwheel1 towards ®.
!
Moving the gear selector lever to positionN
while driving cancels the Distronic. 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).
i
Depressing the accelerator pedal does not
deactivate the Distronic. After brief acceleration
(e.g. for passing), the Distronic will resume the
last speed set.
Warning!
G
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving recom-
mendations for safe following distance.

justs the suspension at all four wheels in
response to various driving situations. It
automatically selects the optimum suspen-
sion tuning and ride height for your vehicle.
Vehicle level control
Your vehicle automatically adjusts its ride
height to:

increase vehicle safety

The lighter socket can accommodate
12V DC electrical accessories (up to a maximum
of 85 W) designed for use with the standard
“cigarette lighter” plug type. Keep in mind, how-
ever, that connecting accessories to the lighter
socket (for example extensive connecting and
disconnecting, or using plugs that do not fit prop-
erly) can damage the lighter socket. With the
socket damaged, the lighter may no longer be
able to be placed in the heating (pushed-in) posi-
tion, or the lighter may pop out too early with the
lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with the stan-
dard “cigarette lighter” plug type to the
12V power outlet (
page 242) in your vehicle
whenever possible.

Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved
external antenna. Refer to the radio trans-
mitter operation instructions regarding use
of an external antenna.You can take and place telephone calls us-
ing the s and t buttons on the
steering wheel. To carry out other tele-
phone functions, use the control system
(
page 165).
See separate instruction manual for in-
structions on how to operate the tele-
phone.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious
personal injury.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. A driver’s
attention to the road must always be
his /her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call.
If you choose to use the telephone
1 while
driving, please use the hands-free device
and only use the telephone when road,
weather, and traffic conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Only operate the COMAND (Cockpit Man-
agement and Data System)
1 if road, weath-
er, and traffic conditions permit.
