Lighting and Horns: Service Precautions

LIGHTING: LIGHTING SYSTEM: PRECAUTION

NOTICE:
When disconnecting the negative (-) battery terminal, initialize the following system after the terminal is reconnected.





1. PRECAUTION FOR USING BATTERY DURING INSPECTION

(a) While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.

2. PRECAUTION FOR HEADLIGHT BULB REPLACEMENT (FOR HALOGEN HEADLIGHT)

(a) If even a thin film of oil is left on the surface of the halogen light, the bulb may be damaged because the light will burn at a higher temperature.

(b) Handle any halogen light with great care. Dropping, hitting or damaging the bulb, in any way, may result in exploding and shattering because the internal pressure is high.

(c) Always prepare a new bulb for immediate replacement. The lens may attract dust and moisture if removed from the vehicle for too long while replacing the bulb.

(d) Always use a bulb of the same wattage for replacement.

(e) Firmly reinstall the socket after bulb replacement.

The lens may become cloudy or the light cavity may fill with water through the gaps around the socket.

3. PRECAUTION FOR HEADLIGHT BULB REPLACEMENT (FOR HID HEADLIGHT)

(a) When any defects such as deformation, cracks, dents, chipping, etc. is identified on the discharge headlight (especially, on the light control ECU), replace it with a new one.

(b) Even if the operation seems to be normal, the fail-safe function may be defective.

(c) Since the bulb of the discharge headlight and halogen bulbs (for headlight or fog light) have pressurized gas inside and can easily be broken if scratched or dropped, special care should be taken. When handling the bulb, hold the plastic or metal part and do not touch the glass part with bare hands.

(d) Never touch the high voltage socket of the discharge headlight with the light control switch in the HEAD position, as this could generate momentary high voltage of 20,000 V and lead to a serious accident.

(e) Never connect a tester to the high voltage socket of the discharge headlight for measurement, as this may result in a serious accident because of high voltage.

(f) When servicing the discharge headlight, do not allow the discharge headlight to come into contact with water. Turn off the light control switch and disconnect the cable from the negative (-) battery terminal and the connector of the light control ECU in advance to avoid electric shocks.

(g) When performing an operation related to the discharge headlight, operate it after assembling has been finished and never turn on the lights without a bulb installed.

(h) Do not turn on the discharge headlight using a power source other than the vehicle battery.
