Lighting and Horns: Service Precautions

LIGHTING: LIGHTING SYSTEM: PRECAUTION

PRECAUTION

1. PRECAUTION FOR DISCONNECTING BATTERY CABLE
NOTE: FOR INITIALIZATION:

When disconnecting the cable from the negative (-) battery terminal, initialize the following system(s) after the cable is reconnected.





NOTE: FOR HYBRID SYSTEM ACTIVATION:
- When the warning light is illuminated or the battery has been disconnected and reconnected, pressing the power switch may not start the system on the first try. If so, press the power switch again.
- With the power switch's power mode changed to ON (IG), disconnect the battery. If the key is not in the key slot during reconnection, DTC B2799 may be output.

2. PRECAUTION OF HEADLIGHT BULB REPLACEMENT (w/o HID)
(a) If even a thin film of oil is left on the surface of the halogen light, its service life will be shortened 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 it exploding and shattering because the internal pressure is high.
(c) Always prepare a new bulb for immediate replacement. While replacing the bulb, the lens may attract dust and moisture if removed from the vehicle for too long.
(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 (w/ HID)
(a) When any defects such as deformation, cracks, dents, chipping, etc. are identified on the HID 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) Be careful not to scratch or drop bulbs of the HID headlight and halogen bulbs (for high beam headlights and fog lights) as they have pressurized gas inside and can be easily broken.
(d) Touching the high voltage socket of the HID headlight with the headlight dimmer switch on could generate a momentary voltage of 20,000 V and lead to a serious injury.
(e) Never connect a tester to the high voltage socket of the HID headlight for measurement, as this may lead to a serious injury because of high voltage.
(f) When servicing the HID headlight, keep it away from water, turn off the light control switch, and disconnect the battery terminal and the connector of the light control ECU in advance to avoid electric shock.
(g) When operating the HID headlight, operate it after assembly is completed and never turn on the lights without a bulb installed.
(h) Do not turn on the HID headlight using a power source other than the vehicle's.
