LIGHTING
The 4-light multi-reflector type headlights are adopted with new styling.
Along with the adoption of the 4-beam headlights, the daytime running light system has been changed
from the '99 model type that uses resistors to dim the low beams. On the 2000 model, the daytime running
light is a type that dims the right and left high beams through a series circuit.

DESCRIPTION
The new Camry has the following features:
Item
Outline
Daytime Running Light System
This system is designed to automatically activate the headlights during the
daytime to keep the car highly visible to other vehicles.
As in the previous model, the headlights are activated by reducing the nor-
mal high beam brightness.
The basic construction and operation are the same as in the previous model.
Light Auto Turn±Off System
When the ignition key is turned from the ON or ACC to LOCK position and
the driver's door is opened with the taillights and headlights turned on, this
system automatically turns them off.
The basic construction and operation are the same as in the previous model.
Light Auto Turn±Off System
This system is useful when entering the vehicle and inserting the ignition key
into the cylinder in the dark.
2 types of this system are used in the new Camry.
In the first type, when the doors are opened, this system turns on the illu-
minations around ignition key cylinder and dome light (only when the con-
trol switch is set to the DOOR position) simultaneously. These lights fade
out in about 15 seconds. However, under certain conditions such as when all
doors are locked, the lights will turn off immediately even if the system is
operating.
The basic construction and operation are the same as in the '97 Avalon.
In the second type, when the door is opened, this system turns on the illu-
minations around the ignition key cylinder. This illumination remains on for
about 5 seconds after the door is closed.

The daytime running light control sensor
is on the top of the passenger 's side
instrument panel.
Do not place anything on the instrument
panel, and/or do not affix anything on the
windshield to block this sensor.High±Low beamsÐFor high beams, turn
the headlights on and push the lever away
from you (position 1). Pull the lever to-
ward you (position 2) for low beams.
The headlight high beam indicator light
(blue light) on the instrument panel will
tell you that the high beams are on.
Flashing the high beam headlights
(position 3)ÐPull the lever all the way
back. The high beam headlights turn off
when you release the lever.
You can flash the high beam headlights
with the knob turned to ºOFFº.TURN SIGNALS
To signal a turn, push the headlight/
turn signal lever up or down to position
1.
The key must be in the ºONº position.
The lever automatically returns after you
make a turn, but you may have to return
it by hand after you change lanes.
To signal a lane change, move the lever
up or down to the pressure point (position
2) and hold it.
If the turn signal indicator lights (green
lights) on the instrument panel flash faster
than normal, a front or rear turn signal
bulb is burned out.

HEADLIGHT (w/ DAYTIME RUNNING LIGHT)
The current from the FL MAIN is always flowing from the MAIN fuse to HEAD relay (Coil side) to TERMINAL H±LP of the
daytime running light relay (Main), from DOME fuse to TERMINAL +B of the daytime running light relay (Main) and from the
ALT fuse to Taillight relay (Coil side) to TERMINAL TAIL (TMMK Made) of the daytime running light relay (Main).
When the ignition SW is turned on, the current flowing through the GAUGE fuse flows to TERMINAL IG of the daytime
running light relay (Main).
1. DAYTIME RUNNING LIGHT OPERATION
When the engine is started, voltage generated at TERMINAL L of the generator is applied to TERMINAL CHG± of the
daytime running light relay (Main). If the parking brake lever is pulled up (Parking brake SW on) at this time, the relay is not
activated so the daytime running light system does not operate. If the parking brake lever is then released (Parking brake
SW off), a signal is input to TERMINAL PKB of the relay.
This activates the daytime running light relay (Main) and the HEAD relay is turned to on, so the current flows from the MAIN
fuse to the HEAD relay (Point side) to TERMINAL 1 of the DIM relay to TERMINAL 4 to H±LP LH (LWR), H±LP RH (LWR)
fuses to TERMINAL 1 of the headlights to TERMINAL 3 to TERMINAL 1 of the daytime running light resistor to TERMINAL 2
to GROUND, causing the headlights to light up (Headlights light up dimmer than normal brightness.). Once the daytime
running light system operates and the headlights light up, the headlights remain on even if the parking brake lever is pulled
up (Parking brake SW on).
If the engine stalls and the ignition SW remains on, the headlights remain light up even through current is no longer output
from TERMINAL L of the generator. If the ignition SW is then turned off, the headlights go off.
If the engine is started with the parking brake lever released (Parking brake SW off), the daytime running light system
operates and headlights light up when the engine starts.
2. HEADLIGHT OPERATION
When the light control SW is switched to HEAD position and the dimmer SW is set to LOW position, causing the daytime
running light relay (Main) and the HEAD relay to turn on, so the current flows from the MAIN fuse to HEAD relay (Point side)
to DRL NO.2 fuse to TERMINAL 3 of the DRL NO.4 relay to TERMINAL 4 to TERMINAL H±ON of the daytime running light
relay (Main) to TERMINAL H to TERMINAL 3 of the integration relay to TERMINAL 4 to TERMINAL 13 of the light control
SW to TERMINAL 16 to GROUND, activating the DRL. NO.4 relay. The current to HEAD relay (Point side) then flows to
TERMINAL 1 of the DIM relay to TERMINAL 4 to H±LP LH (LWR), H±LP RH (LWR) fuses to TERMINAL 1 of the headlights
to TERMINAL 3 to TERMINAL 1 of the DRL NO.4 relay to TERMINAL 2 to GROUND, causing the headlights to light up at
normal intensity.
When the light control SW is switched to HEAD position and the dimmer SW is set to HIGH position, the signal from the
dimmer SW is input to the daytime running light relay (Main). This activates the daytime running light relay (Main) and the
HEAD relay is turned on, so the current flows from the MAIN fuse to HEAD relay (Point side) to TERMINAL 1 of the DIM
relay to TERMINAL 3 to TERMINAL DIM of the daytime running light relay (Main), activating the DIM relay. This causes
current to flow from TERMINAL 1 of the DIM relay to TERMINAL 2 to HEAD LH (UPR), HEAD RH (UPR) fuses to TERMINAL
2 of the headlights to TERMINAL 3 to TERMINAL 1 of the DRL NO.4 relay to TERMINAL 2 to GROUND, causing the
headlights to light up at high beam and the high beam indicator light to light up.
When the dimmer SW is switched to FLASH position, the signal from the dimmer SW is input to the daytime running light
relay (Main). This activates the daytime running light relay (Main) and the HEAD relay is turned on, so the current flows from
the MAIN fuse to HEAD relay (Point side) to DRL NO.2 fuse to TERMINAL 3 of the DRL NO.4 relay to TERMINAL 4 to
TERMINAL H±ON of the daytime running light relay (Main) to TERMINAL H to TERMINAL 8 of the dimmer SW to
TERMINAL 16 to GROUND, activating the DRL NO.4 relay. At the same time, the current flows from the TERMINAL 1 of the
DIM relay to TERMINAL 3 to TERMINAL DIM of the daytime running light relay (Main), activating the DIM relay, and also
flows from the HEAD LH (UPR), HEAD RH (UPR) fuses to TERMINAL 2 of the headlights to TERMINAL 3 to TERMINAL 1 of
the DRL NO.4 relay to TERMINAL 2 to GROUND, causing the headlights to light up at high beam and the high beam
indicator light to light up.
SYSTEM OUTLINE

3. AUTOMATIC LIGHT CONTROL OPERATION
When the daytime running light is operating and the Automatic control sensor detects a decrease in the ambient light (It
continues less than approx. 2500 lux over about 20 seconds, and it is less than 1000 lux.), the automatic light control
operation starts. At the same time, daytime running light relay (Main) is activated, so current flows from the ALT fuse to the
Taillight relay (Coil side) to TERMINAL TAIL of the daytime running light relay (Main), and the DRL NO.2 fuse to the DRL
NO.4 relay (Coil side) to TERMINAL H±ON of the daytime running light relay (Main), activating both the Taillight relay and the
DRL NO.4 relay, so that the taillights and headlights light up.
When the automatic light control sensor detects an increase in the ambient light (It continues more than approx. 1000 lux
over about 20 seconds, and it is more than approx. 2500 lux), the ignition SW is turned to off, the light control SW is turned to
HEAD position, and the automatic light control operation stops.
