315 Technical terms
Tele Aid System*
(T
elematic A
larm I
dentification on
D
emand)
The Tele Aid system consists of three
types of response: automatic and man-
ual emergency, roadside assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.
Telematics*
A combination of the terms “telecom-
munications” and “informatics”.
Tightening torque
Force times lever arm (e.g. a lug
wrench) with which threaded fasteners
such as wheel bolts are tightened.Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is ap-
proved.
Traction
Force exerted by the vehicle on the
road via the tires.
Transfer case
Speed of rotation / torque converter
that works together with the ->auto-
matic transmission. In the LOW mode
off-road position, the transfer case de-
creases the output rotational speed of
the ->automatic transmission by ap-
proximately half. This results in a corre-
sponding increase of torque on the
drive axles.
The vehicle then has nearly double the
driving force but drives only approxi-
mately half as fast.TWR
(T
ongue W
eight R
ating)
The TWR is the maximum permissible
weight on the trailer tongue.
VIN
(V
ehicle I
dentification N
umber)
The number set by the manufacturer
and placed on the body to uniquely
identify each vehicle produced.
Voice control system*
Voice control system for car phones,
portable cell phones and audio sys-
tems (radio, CD, etc.).

Notes on installation of GPS antenna
The GPS antenna should be installed only in a vertical position with a maximum deviation of 10° from
horizontal.
The GPS antenna should always have a free view of the sky. Thermal insulated windows can significantly
reduce the function of the GPS antenna.
When installing the GPS antenna, always ensure that the arched surface points away from the vehicle.
Changing the installation location inside of the vehicle after the system is put into operation has no effect on the
GPS reception.
NOTES ON RADIO CONNECTOR PIN ASSIGNMENT - AH82.61-P-0001-05A
Model 163
The pin assignment in the radio connector has been changed on vehicles as of 07.99 (model year 2000)
Fig. 1: Identifying Radio Connector Pin Assignment

Check pin assignment
If the pin assignment is the same as listed in the table above, it is not necessary to install the adapter
wiring harness and CAN bus adapter when installing the Audio 30 APS navigation system.

Models 129, 163, 168, 170, 202, 208, 210
Vehicles with telephone code 316 or 317 can be retrofitted with an Audio 30 APS navigation system.
Ensure that the Audio 30 APS navigation system is a unit with part number A 208 820.....Older units with part
number A 168 820 .. .. are not capable of assuming the master function in the D2B- ring.

The Audio 30 APS does not have a number pad. For this reason, it is not possible to control the telephone over
the radio (see operating instructions).
On vehicles (as of approx. 07.99) with multifunction steering wheel (telephone control with keys on steering
wheel) this function is then also possible with the Audio 30 APS navigation system.

Customer information, installation position for GPS antenna
There are two different installation locations for the GSP antenna:
1. Standard GPS antenna from DaimlerChrysler on roof or trunk lid. This version offers the best reception
and is therefore preferable.
2. Use of magnetic antenna in vehicle passenger compartment. This version is part of the kit from the
Becker company and installation is described in Becker installation instructions.
Notes on installation of Becker GPS antenna
The GPS antenna can only be installed horizontally with a maximum deviation of 10° from horizontal.
The GPS antenna should always have an unobstructed view of the sky. Tinted windows can reduce the function
of the GPS antenna considerably.
When installing the GPS antenna always ensure that the arched surface of the antenna points upwards.
