Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use, es-
pecially on hills. Always try to use the jack
on level surface.
Make sure that the jack arm is fully seated
in the jack take-up bracket. Always lower
the vehicle onto sufficient capacity jack-
stands before working under the vehicle.

System Control Unit
Position of the identification
For vehicle models 170, 202, 203, 208, 210, 215, 220, 230, 463 an identification plate is located on the fiber
optic cable wiring harness behind the radio on which the fiber optic cable modules (1, 2, 3, 4) specially fitted to
these vehicles are specified together with their exact length.
With models 129, 414 the identification plate is in the trunk next to the CD changer.
With model 168, the identification plate is in the passenger footwell in the area of the control unit box. If there
is no length specification on the identification plate, the respective fiber optic cable module must be removed
and the necessary length measured.
Vehicle model 163 does not have any identification plate.
With repairs, the individual fiber optic cable modules with corresponding length specification can be ordered
(see spare-parts documentation Group 82).

Routing
The inserts (5) of the fiber optic cable modules may only be routed as in production. The fiber optic cable
modules must always be pr ovided with a protective cap when routing. For every vehicle model, the sequence of
components in the D2B ring is specifically predetermi ned. The components are connected by fiber optic cable
modules. They are secured to a wiring ha rness with an orange-colored casing.
Fig. 4: Identifying Fiber Optic Cable Modules Insert

Danger of breaking! Do not kink fiber optic cable, route over sharp edges or be nd in radii smaller than 25
mm. Tensile forces on inserts must not exceed 65 N.
The fiber optic cable must not be exposed to temperat ures greater than 85°C or lower than -40°C. Do not
squeeze fiber optic cable, in other words do not compress with clamps or cable ties.
Connection between the devices
The Digital Data Bus ring (D2B) connects the new ra dio generation and COMAND (monitor) to the CD
changer (CDC) (USA preinstallati on), telephone and portable CTEL. The sound amplifier remains wired as
COMAND (monitor) to the CD changer (CDC) (USA preinstallation), telephone and portable CTEL. The sound
amplifier remains wired as befo re with Models 129, 170, 202, 208 and 210. The radio and COMAND as head
unit (HU) performs the master function and also forms the interface to the Control Area Network bus Class B
(interior) (CAN-B) (for vehicles wi th multifunction steering wheel).
