Description
IThe vertical direction of the headlamp projection can be adjusted from inside the vehicle to prevent the
headlamp beam axis from facing upward due to a change in the number of occupants and load conditions
in the vehicle.
IA little Electronic Control Unit (ECU) is incorporated in each actuator (one for each headlamp), which
compares a signal voltage (V
signal), coming from the headlamp aiming switch, with battery voltage (12V).
The signal voltage varies with the position of the switch.
Related to the difference in voltage the actuator rod will move more or less and adjust the headlamp beam
angle accordingly.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replacable
halogen bulb. The bulb can be replaced from the engine compart-
ment side without removing the headlamp body.
IGrasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the
bulb.
3. Pull off the rubber cap.
4. Press end of the retaining pin together to release bulb.
5. Remove the headlamp bulb. Do not shake or rotate the bulb
when removing it.
6. Install the new bulb in reverse order of removal.
CAUTION:
IDo not leave the bulb out of the headlamp reflector for a
long period of time as dust, moisture, smoke, etc. may
enter the headlamp body and affect the performance of the
headlamp. Thus, the headlamp bulb should not be
removed from the headlamp reflector until just before a
replacement bulb is to be installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. For operating
instructions, of any aimer, it should be in good repair, calibrated and
used according to respective operation manuals supplied with the

System Description
Refer to Owner's Manual for audio system operating instructions.
NATS AUDIO LINK
Description
The link with the NATS IMMU implies that the audio unit can basically only be operated if connected to the
matching NATS IMMU to which the audio unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the audio unit is basically
useless since special equipment is required to reset the audio unit.
Initialization process for audio units that are linked to the NATS IMMU
New audio units will be delivered to the factories in the ªNEWº state, i.e. ready to be linked with the vehicle's
NATS. When the audio unit in ªNEWº state is first switched on at the factory, it will start up communication
with the vehicle's immobiliser control unit (IMMU) and send a code (the ªaudio unit Codeº) to the IMMU. The
IMMU will then store this code, which is unique to each audio unit, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will confirm correct receipt of the audio unit code to the audio
unit. Hereafter, the audio unit will operate as normal.
During the initialisation process, ªNEWº is displayed on the audio unit display. Normally though, communica-
tion between audio unit and IMMU takes such a short time that the audio unit seems to switch on directly
without showing ªNEWº on its display.
Normal operation
Each time the audio unit is switched on afterwards, the audio unit code will be verified between the audio unit
and the NATS before the audio unit becomes operational. During the code verification process, ªWAITº is
shown on the audio unit display. Again, the communication takes such a short time that the audio unit seems
to switch on directly without showing ªWAITº on its display.
When the radio is locked
In case of a audio unit being linked with the vehicle's NATS (immobilizer system), disconnection of the link
between the audio unit and the IMMU will cause the audio unit to switch into the lock (ªSECUREº) mode in
which the audio unit is fully inoperative. Hence, repair of the audio unit is basically impossible, unless the audio
unit is reset to the ªNEWº state for which special decoding equipment is required.
Clarion has provided their authorized service representatives with so called ªdecoder boxesº which can bring
the audio unit back to the ªNEWº state, enabling the audio unit to be switched on after which repair can be
carried out. Subsequently, when the repaired audio unit is delivered to the final user again, it will be in the
ªNEWº state as to enable re-linking the audio unit to the vehicle's immobiliser system. As a result of the above,
repair of the audio unit can only be done by an authorized Clarion representative.
Service instruction
Item Radio linked with IMMU and/or SECU
Battery disconnection No additional action required
Radio needs repair Repair needs to be done by authorised representative of radio manufacturer since radio
cannot be operated unless it is reset to NEW state, using special decoding equipment
Replacement of radio by new part Radio is delivered in NEW state. If possible, the radio will automatically link up with the
immobiliser system. If this appears not possible, CATS code needs to be manually input
Transferring radio to another vehicle /
replacement of radio by an ªoldº partRadio needs to be reset to NEW state by authorised representative of radio manufac-
turer
Replacement of IMMU by new part Radio will request for CATS code input prior to establishing the link with the IMMU
Replacement of IMMU by old part If a radio code has already been stored in memory of the IMMU, the radio cannot be
linked to it. After switching on the radio, it will display ªSECUREº after 1 minute. Opera-
tion can only be established after resetting the ratio by an authorised representative of
radio manufacturer
CATS code input procedure
1. Radio displays ªCODE INº after the power is switched ON.
2. Enter CATS code (4-digits) by pressing the preset buttons (using 1 to 4).
Press the preset buttons for the necessary amount of times for the number of each digits.
e.g. CATS code is ª5432º
Press No. 1 preset button for 5 times
Press No. 2 preset button for 4 times
