PRECAUTIONS
1.
2.
PRECAUTIONS WHEN REPLACING HEADLIGHT BULBS
(a) Because halogen lights become extremely hot when in use, the
life of the bulb may be reduced in the event that the surface of
the bulb comes in contact with oil or another similar substance.
When replacing the bulb, hold the flange part and do not touch
the glass with your bare hands.
(b) Halogen bulbs have pressurized gas inside and can be
damaged or shattered if dropped, bumped or scratched.
(c) Because dirt and moisture can enter the lens of a bulb that is
removed and left out for a long period of time, have a new bulb
on hand before performing bulb replacement.
(d) When replacing a bulb, always use a bulb of the same
specification.
(e) When replacing one-sided bulbs, keep in mind that there is a
difference in the brightness and luminescent color of left and
right bulbs.
(f)
If bulbs are not properly installed in their sockets, water and
mist may get inside the lens. Therefore, after replacing bulbs,
make sure that they have been securely installed.
(g) Flying glass shards can cause injury. Therefore, do not break
bulbs when disposing of them after use.
PRECAUTIONS WHEN ADJUSTING HEADLIGHT BEAMS
(a) Do not cover a headlight for more than 3 minutes when the
headlights are ON.
(b) Because the outer lens of the headlight is made of resin, there
is a possibility that the outer lens may melt if it is covered for too
long while the adjustments are made.
OPERATION CHECK
1.
BEFORE YOU TROUBLESHOOT
(a) Basic inspection
(1) Using a tester, measure the voltage of the battery.
Standard:
10 to 14 V (during engine stop)
(b) Visually check for broken light bulbs, broken fuses,
disconnected wire harnesses, short circuits and connectors with
bad connections.
2.
CHECK HEADLIGHT MANUAL LEVELING FUNCTION (VEHICLES
WITH HALOGEN HEADLIGHTS)
(a) With the ignition switch ON, turn the headlight dimmer switch
assembly to the OFF → HEAD position. When the headlight
leveling switch is re-enabled, check that the reflector is
activated and that the headlight beam changes.
3.
CHECK ILLUMINATED ENTRY SYSTEM ACTIVATION
HINT:
The applicable lights are shown below.
• MAP LIGHT ASSEMBLY (VEHICLES WITH A MAP LIGHT)
• ROOM LIGHT ASSEMBLY NO. 1 (VEHICLES WITHOUT A MAP
LIGHT)
LI
LI–2
LIGHTING - LIGHTING SYSTEM
• ROOM LIGHT ASSEMBLY NO. 2
(a) Perform the following operations to check that the lights come
on under the appropriate conditions.
(1) With the ignition switch (IG) OFF, close all the doors and
lock the driver side door.
(2) With the doors unlocked, check that each light comes on
when any of the doors is opened, and check that the lights
go out 15 seconds after the doors are closed.
(3) With the ignition switch (IG) ON, check that when any of
the doors is opened and then closed, each light goes out
immediately.
(4) Starting with the ignition switch (IG) OFF, check that the
lights go out immediately when any of the doors is opened
and the ignition switch (IG) is turned on within 15 seconds
(i.e., before the time at which the lights are supposed to
go out automatically).
(5) With the ignition switch (IG) OFF, and with the doors open
and each light illuminated, check that the lights go out
immediately when the driver side door is locked within
around 15 seconds (i.e., before the time at which the
lights are supposed to go out automatically).
LI
4.
INSPECT BATTERY SAVER FUNCTION
(a) With the ignition (IG) OFF, check that each lamp that is
illuminated by the illuminated entry control (lights are
illuminated when any of the doors is opened) goes out after
about 10 minutes.
HINT:
With the ignition switch (IG) ON, or, with the doors closed, the
battery saver system is cancelled.
BASIC INSPECTION
1.
CHECK OPERATION
(a) Check the operation of the lights.
(1) Visually check the operation of the vehicle's exterior
lights.
• HEADLIGHTS (HI-LO MODES)
• CLEARANCE LIGHTS
• TAILLIGHTS
• STOP LIGHTS
• BACK-UP LIGHTS
• LICENSE PLATE LIGHTS
• TURN SIGNAL LIGHTS
• HAZARD LIGHTS
• FOG LIGHTS
Standard:
Illumination is normal.
2.
CONDITION OF INSTALLATION
(a) Check the installation of the lights.
(1) Wiggle the lights with your hand to check that they are
properly installed.
Standard:
The lights are not loose.
LIGHTING - LIGHTING SYSTEM
(2)
LI–3
Check that there is no damage, such as discoloration or
cracks, to the reflectors or lenses of the lights. In addition,
check for dirt and water penetration on the inside of the
lamp.
Standard:
There is no damage, such as discoloration or
cracks.
There is no dirt or water penetration.
