Authorization is required in the following cases:
- When the system is initially started up.
- With a new SIM card (Subscribe Identification Module) for TELE AID
- When the vehicle owner changes
- After expiration of a period of 6 months following last authorization (this procedure is accomplished automatically in the background).

During authorization a check is accomplished via mobile telephone:
- The validity of the SIM card (for TELE AID) installed in the telephone transmitter/receiver and TELE AID, D2B (A35/17).

NOTE: TELE AID SIM is not installed ex factory in all vehicles. The card is installed on vehicles model series A208, 215 and 220 and on vehicle model series 129, W203, C208 and 210 the card must be installed by the dealer.

To ensure a trouble-free operatic, the following should be avoided during authorization:
- Actuating an emergency alarm/telediagnosis or
- switching off the ignition or
- switching off the telephone or
- setting TELE AID to diagnosis mode (via STAR diagnosis).

NOTE: Misuse of emergency call alarm is subject to punishment!

Procedure when alarm is triggered erroneously.
If an emergency call is triggered erroneously in the workshop it is not possible to interrupt it even disconnecting the battery. In this case always wait until voice contact is made with police. Then inform police of unintentional actuation to prevent rescue vehicles from starting their rescue service.

Authorization procedure for TELE AID emergency call, TELE AID telediagnosis

NOTE: Only the GSM reception is required for the authorization sequence. This means that authorization can be accomplished where mobile telephones function as well.

Ancillary work
- The salesperson must submit the application together with the user and complete the transfer process to the user.
- The mechanic must perform the authorization process, i.e. he must ensure that a vehicle with functioning telematic services is handed over to the user.

Application and application shipping for TELE AID
Together with the user the salesperson must completely prepare two application forms (debitel order telematic and debitel card order for Mercedes-Benz special equipment) and send them to debitel.

When filling out the applications ensure that the data (vehicle chassis number, vehicle license plate, GSM number) is completely and correctly entered, otherwise it is not possible to perform the authorization. It is particularly important to enter the authorization date (access authorization date).

After filling out the applications send to the CAC (Customer Assistance Center) (fax).

Checking delivery date
Authorization of TELE AID is performed on the day entered in the application for access authorization.

This deadline depends on the delivery date of the vehicle from the Mercedes-Benz plant. The salesman coordinates the transfer date with the user and plans the date for the access authorization.

The dealer picks up the confirmation for the delivery date from Mercedes-Benz and then plans the date for access authorization.

NOTE: The authorization works only on this particular day (key word: Authorization for specific day, the authorization messages are transmitted to the telephone transmitter/receiver and TELE AID, D2B (A35/17) by the service centers via the GSM network. This is only accomplished on a particular day, i.e. the access authorization date.

Modifying access authorization date
If the day of the authorization is postponed, inform CAC about the the new deadline (telephone fax).

For precise identification of the vehicle to be authorized the CAC requires the data of the telematic application.

If the CAC is not informed about the modification of the access authorization date the dealer is not able to perform an authorization (changing form for access authorization date).

Before starting the actual authorization check the following list. Refer to the checklist to ensure that the authorization is prepared in full.

1. The TELE AID SIM card is installed in the telephone transmitter/receiver and TELE AID, D2B (A35/17)
2. The telephone transmitter/receiver and TELE AID, D2B (A35/17) is programmed.
- If the telephone transmitter/receiver and TELE AID, D2B (A35/17) is installed ex factory it is already programmed at the company.
- If the telephone transmitter/receiver and TELE AID D2B is a replacement unit it should be programmed on site.
3. TELE AID is applied for (telematic application sent to debitel)
4. In the handset is no SIM card inserted
5. The authorization corresponds to the access authorization day on the telematic application
6. PIN for TELE AID SIM card is known

NOTE: The PIN is stored in the letter of the telephone card, which can only be opened when the customer is present.

Authorization sequence
1. Switch on c. 15 R (ignition)
2. Display on handset informs that no telematic services (error message in instrument cluster) are available
3. Display on handset informs that the service mode* is presently active, quit this mode
4. Display on handset requests PIN for TELE AID SIM, enter PIN on handset (entered numbers are not indicated, only space holders (asterix)
5. Display on handset requests further processing steps for entered PIN code, store PIN, which is absolutely necessary for using TELE AID
6. Automatic authorization is now started and completed after 15 minutes. C. 15 R should be switched on during this time.

Service mode*
The service mode on the telephone transmitter/receiver and TELE AID, D2B (A35/17) deactivates the automatic switchover of the system to the additional battery, when the main power supply is interrupted. The service mode is switched on by STAR diagnosis. It is also switched off by STAR diagnosis or via the handset.

Following authorization the error messages in the instrument cluster are erased. If the error messages are not erased after an expiration of 15 minutes a malfunction is present.

NOTE: Switch ignition on and off after authorization time.

Error limitation
If both error messages are still active both services could not be authorized. If only one error message is active this service could not be authorized.

Reading out DTC's
Read out DTC of the telephone transmitter/receiver and TELE AID, D2B (A35/17) by means of STAR diagnosis. Compare chassis number stored in the telephone transmitter/receiver and TELE AID, D2B (A35/17) with chassis number in vehicle papers. If error on the vehicle and on the telephone transmitter/receiver and TELE AID, D2B (A35/17) could be excluded contact CAC. The CAC helps authorizing TELE AID. Chassis number and DTC's are required for this purpose. Moreover, they check whether the access authorization date coincide with the date specified by CAC. The CAC clarifies together with dealer the error cause for the services (TELE AID emergency call/telediagnosis). Then authorization is performed again.

Handing over vehicle
Following authorization the vehicle can be handed over to the user.

Coordinating later authorization date

A new TELE AID authorization date should be agreed upon with user.

On this specific day the vehicle should be present in the workshop. The CAC is informed about the new access authorization date in due time. Inform the user that the TELE AID is not operative and have him sign a confirmation form ("Shut-down confirmation form").

TELE AID should not be authorized
The vehicle is, however, equipped with a TELE AID system, the TELE AID service should not be authorized (no telematic application present). The user is informed, that the system does not work and signs a form for confirmation (preprinted form). The error messages indicated in the instrument cluster are deactivated by STAR diagnosis. Glue sticker (out or order) on cover of emergency call pushbutton (S93/3). Ensure that the CTEL and TELE AID

Transmitter/receiver, D2B (A35/17) is no longer in the production mode*
(with STAR Diagnosis).
The production mode deactivates all TELE AID services. The production mode is used in the Mercedes-Benz plant and is switched off at the end of the line. The production mode is also switched off when the TELE AID service is authorized. If the CTEL and TELE AID transmitter/receiver, D2B (A35/17) is not authorized, because the user does not want the authorization, it is essential to exit from the production mode with the STAR Diagnosis.

Deauthorization
