2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)
(a) Brake System Warning Light and
Buzzer
This light comes on in the following cases
when the ignition key is in the ONº posi-
tion.

When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is turned to the
ONº position even after the parking brake
is released.
If the vehicles speed rises above 5 km/h
(3 mph) with the parking brake applied, a
buzzer sounds.

When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following cases:

The light does not come on even if the
parking brake is applied when the igni-
tion key is in the ONº position.

The light does not come on even if the
ignition key is turned on with the park-
ing brake released.A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Toyota dealer.

The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.

The brake system warning light re-
mains on together with the ABSº
warning light.
In this case, not only the anti- lock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver's Seat Belt Reminder Light
and Buzzer
The light and buzzer act as a reminder to
buckle up the driver's seat belt.
Once the ignition key is turned to ONº,
the reminder light flashes and buzzer
sounds if the driver 's seat belt is not fas-
tened. Unless the driver fastens the belt,
the light continues flashing and the buzzer
stops after about 4 to 8 seconds.
(c) Front Passenger 's Seat Belt
Reminder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to ONº,
the reminder light flashes if a passenger
sits in the front passenger seat and does
not fasten the seat belt.
If luggage or other load is placed on the
front passenger seat, depending on its
weight, the reminder light may flash.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.

With the ignition SW turned on, the current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 2 of the
front wiper motor through the WIPER fuse, the current flows to TERMINAL 1 of the washer motor through WASHER fuse.
1. Low Speed Position
With the wiper SW turned to LOW position, the current flows through TERMINAL 17 of the front wiper and washer SW to
TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and causes the wiper motor to run at low
speed.
2. High Speed Position
With the wiper SW turned to HIGH position, the current flows through TERMINAL 17 of the front wiper and washer SW to
TERMINAL 8 to TERMINAL 4 of the front wiper motor to TERMINAL 5 to GROUND and causes the wiper motor to run at
high speed.
3. INT Position
With the wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows
through TERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This flow of current operates the
intermittent circuit and the current flows through TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to
TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and the wiper functions.
The intermittent operation is controlled by a condenser's charged and discharged function installed in the relay and the
intermittent time is controlled by a time control SW to charge the charging time of condenser.
4. Washer Continuous Operation
With the washer SW pulled to on, the current flows through TERMINAL 1 of the washer motor to TERMINAL 2 to TERMINAL
11 of the front wiper and washer SW to TERMINAL 2 to GROUND and causes the washer motor to run and the window
washer to jet. This causes the current to flow to washer continuous operation circuit in TERMINAL 17 of the front wiper and
washer SW to TERMINAL 7 to TERMINAL 1 of the front wiper motor to TERMINAL 5 to GROUND and the wiper functions.
C14 Combination SW
2-Ground : Always continuity
17-Ground : Approx. 12 volts with the ignition SW at ON position

NOTICE

Be sure the engine and all accesso-
ries are off before performing main-
tenance.

When checking the battery, remove
the ground cable from the negative
terminal (- º mark) first and rein-
stall it last.

Be careful not to cause a short cir-
cuit with tools.

Take care no solution gets into the
battery when washing it.
If the battery is disconnected or run
down, the moon roof may not operate
automatically and the jam protection func-
tion will not function correctly after you
reconnect, replace or recharge the battery.
In any of these cases, you should normal-
ize the moon roof. To normalize the moon
roof, see Electric moon roofº on page 36
in Section 1- 2.

During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed
on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re-
charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION

Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.

Only do a slow charge (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
