384 Technical termsCOMAND
(C
ockpit M
anagement and D
ata Sys-
tem)
Information and operating center for
vehicle sound and communications
systems, including the radio and navi-
gation system, as well as other optional
equipment (CD changer, telephone,
etc.).
Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to ad-
just settings.
Cruise control
A driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:


If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.


If a slower moving vehicle is ahead,
Distronic will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
minimum following distance.
Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced.Engine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
ESP
(E
lectronic S
tability Pr
ogram)
Improves vehicle handling and direc-
tional stability.
ETD
(E
mergency T
ensioning D
evice)
Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem's threshold to tighten the seat
belts.

Display field in the speedometer used
to present information provided by the
control system.
Multifunction steering wheel
Steering wheel with buttons for operat-
ing the control system.
Overspeed range

of the tachometer dial. Avoid this en-
gine speed range, as it may result in se-
rious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Parktronic*
System which uses visual and acoustic
signals to assist the driver during park-
ing maneuvers.
Poly-V-belt drive
Drives engine-components (alternator,

Transmission


Transfer case


Drive shaft


Differential


Axle shafts/axlesProgram mode selector switch
Used to switch the automatic transmis-
sion between sport operationS and
comfort operationC.

shift control and manual shift program:
in addition toS andC (see above), you
can use theM for manual operation.
Remote Vehicle Diagnostics
Transmission of vehicle data and cur-
rent location to the Mercedes-Benz
Customer Assistance Center for sub-
scribers to Tele Aid service.
REST
(Residual engine heat utilization)
Feature that uses the engine heat
stored in the coolant to heat the vehi-
cle interior for a short time after the en-
gine has been turned off.
Restraint systems
Seat belts, belt tensioners, airbags and
child restraint systems. As indepen-
dent systems, their protective func-
tions complement one another.

RON
(R
esearch O
ctane N
umber)

line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as AN-
TI-KNOCK INDEX.
Shift lock
When the vehicle is parked, this lock
prevents the transmission selector le-
ver from being inadvertently moved out
of positionP without SmartKey turned
and brake pedal depressed.
