Lighting and Horns: Service Precautions
LIGHTING (EXT): LIGHTING SYSTEM: PRECAUTION
1. PRECAUTION FOR HID HEADLIGHT SYSTEM
(a) When any defects such as deformation, cracks, dents, chipping, etc. are identified on an HID headlight (especially on the light control ECU), replace the headlight with a new one.
(b) Even if the operation seems to be normal, the fail-safe function may be defective.
(c) Since an HID headlight bulb has 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) When the HID headlights illuminate, a high voltage (approximately 20000 V) is applied momentarily to the bulb sockets. Never connect a tester to the high voltage socket of an HID headlight for measurement as this may result in a serious accident because of high voltage.
(e) When servicing an HID headlight, do not allow the HID headlight to come into contact with water. Turn off the headlight dimmer switch, disconnect the cable from the negative (-) battery terminal and disconnect the connector of the light control ECU in advance to avoid electric shocks.
(f) When performing work related to the HID headlights, be sure to check the headlight operation after work is completed and never turn on the headlights if bulbs are not installed.
(g) Do not turn on the HID headlights using a power source other than the vehicle battery.
(h) Never connect a tester to the high voltage socket of the discharge headlight for measurement, as this may result in a serious accident due to high voltage.
(i) The light color emitted by the HID headlight bulb varies across the ages.
2. PRECAUTION FOR HEADLIGHT BULB REPLACEMENT
(a) If even a thin film of oil is left on the surface of an HID headlight bulb or halogen bulb, its service life will be shortened because the light will burn at a higher temperature. When replacing a bulb, be sure to hold the flanged part of the light so that your hand does not contact the glass part of the light.
(b) As the internal pressure of HID headlight bulbs and halogen bulbs is high, dropping, hitting or damaging a bulb may result in it exploding and shattering.
(c) Always prepare a new bulb for immediate replacement. While replacing a bulb, the lens may attract dust and moisture if removed from the vehicle for a long time.
(d) Always replace a bulb with another bulb of the same wattage.
(e) If only replacing the bulb on one side, differences in brightness and lighting color between the right and left sides may occur.
(f) Securely install the socket after bulb replacement. The lens may become cloudy or the light cavity may fill with water through gaps around the socket if the socket is not installed securely.
(g) Do not break the HID headlight bulb when disposing of it as shards of glass may fly off and cause injuries.
(h) As an HID headlight bulb cannot be determined to be defective or not by checking it visually, check it by replacing the bulb with a normally functioning one.
3. PRECAUTION FOR AUTOMATIC HIGH BEAM SYSTEM
(a) General Description
The automatic high beam system is a system that helps ensure visibility by automatically changing between the high beams and low beams. In addition, due to control limitations of the automatic high beam system, it may be necessary to manually change between high beams and low beams. For safety reasons, make sure to switch the high beams and low beams manually according to the driving conditions.
(b) Conditions Unsuitable for Using Automatic High Beam System
Under the following conditions, the automatic high beam system might not detect other vehicles or lights correctly, or the high beams might cause glare or flash pedestrians or the occupants of other vehicles. Manual operation should be considered.
(c) Windshield Replacement Precautions
The timing of the change between high beams and low beams differs depending on the light transmission rate of the glass. For this reason, when replacing the windshield, replace it with an original equipment part.
(d) Inner Rear View Mirror Assembly Handling Precautions
Failure to observe the following precautions may result in a malfunction:
Do not touch the lens of the camera (built into the inner rear view mirror assembly) with bare hands.
Do not allow anything to adhere to the camera lens (built into the inner rear view mirror assembly).
Do not subject the inner rear view mirror assembly to strong impacts.
Do not allow any liquids to contact the inner rear view mirror assembly.
