2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range. The farther you are
from a station, the weaker its signal will
be. In addition, reception conditions
change constantly as your vehicle moves.
Here are some common reception prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifting stationsÐGenerally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may
notice fading and drifting, which increase
with the distance from the radio transmit-
ter. They are often accompanied by distor-
tion.
Multi- pathÐFM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this
happens, the signals will cancel each oth-
er out, causing a momentary flutter or
loss of reception.Static and flutteringÐThese occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swappingÐIf the FM signal you
are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the origi-
nal signal can be picked up again.
AM
FadingÐAM broadcasts are reflected by
the upper atmosphereÐespecially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound
alternately strong and weak.
Station interferenceÐWhen a reflected sig-
nal and a signal received directly from a
radio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
StaticÐAM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static.CARING FOR YOUR CASSETTE PLAYER
AND TAPES
For the best performance for your cas-
sette player and tapes:
Clean the tape head and other parts regu-
larly.
A dirty tape head or tape path can
decrease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)
Use high- quality cassettes.
Low- quality cassette tapes can cause
many problems, including poor sound,
inconsistent playing speed, and
constant auto- reversing. They can also
get stuck or tangled in the cassette
player.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player
if you are not listening to it, especially
if it is hot outside.
Store cassettes in their cases and out
of direct sunlight.

Low quality discs
Labeled discs
NOTICE
Do not use special shaped, transpar-
ent/translucent, low quality or labeled
discs such as those shown in the il-
lustrations. The use of such discs
may damage the player or changer, or
it may be impossible to eject the
disc.
Correct Wrong
Handle compact discs carefully, espe-
cially when you are inserting them.
Hold them on the edge and do not
bend them. Avoid getting fingerprints
on them, particularly on the shiny side.
Dirt, scratches, warping, pin holes, or
other disc damage could cause the
player to skip or to repeat a section of
a track. (To see a pin hole, hold the
disc up to the light.)
Remove discs from the compact disc
player when you are not listening to
them. Store them in their plastic cases
away from moisture, heat, and direct
sunlight.

Previous automatic transaxle have selected each gear shift using mechanically controlled throttle hydraulic pressure,
governor hydraulic pressure and lock-up hydraulic pressure. The electronically controlled transmission, however, electrically
controls the line pressure, throttle pressure, lock-up pressure and accumulator pressure etc. through the solenoid valve. The
electronically controlled transmission is a system which precisely controls gear shift timing and lock-up timing in response to
the vehicle's driving conditions and the engine condition detected by various sensors. It makes smooth driving possible by
shift selection for each gear which is the most appropriate to the driving conditions at that time, and by preventing downing,
squat and gear shift shock when starting off.
1. Gear Shift Operation
During driving the engine warm up condition signal is input from engine coolant temp. sensor to TERMINAL THW of the
engine control module, and the vehicle speed signal is input from the ABS speed sensor to skid control ECU, and are sent to
the engine control module through communication control. At the same time, the throttle valve opening signal is sent from
the throttle position sensor to the TERMINALS VTA1 and VTA2 of the engine control module, as the throttle angle signal.
2. Lock-Up Operation
When the engine control module decides based on each signal that the lock-up condition has been met, the current flows
through TERMINAL DSL of the engine control module to TERMINAL 3 of the electronically controlled transmission solenoid
to GROUND.
3. Stop Light SW Circuit
If the brake pedal is depressed (Stop light SW on) when driving in lock-up condition, a signal is input to TERMINAL STP of
the engine control module. The engine control module operates and cuts the current to the solenoid to release lock-up.
4. Overdrive Circuit
*O/D main SW on
When the O/D main SW is turned on, a signal is input to TERMINAL ODMS of the engine control module and engine
control module operation causes gear shift when the conditions for overdrive are met.
*O/D main SW off
When the O/D main SW is turned off, a signal is input into TERMINAL ODMS of the engine control module, and turns on
the O/D off indicator light. This activates the ECU, and the transmission system is controlled not to shift to overdrive.

VSC and Tire Pressure Warning System
1. ABS Operation
If the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the four
wheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedal
is depressed suddenly, the skid control ECU with actuator controls the solenoids in the actuators using the signals from the
sensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the
skid control ECU with actuator detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the
solenoids in the actuators to increase the braking pressure.
2. Traction Control Operation
The traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of the
wheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stability
corresponding to the road conditions.
3. VSC Operation
Unexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under- or
over-steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes to
reduce the under- or over-steering.
To reduce large over-steering :
If the VSC system determines that the over-steering is large, it activates the brakes for the outer front turning wheels
depending on the degree of the over-steering to produce the moment toward the outside of the vehicle and reduce the
over-steering.
To reduce large under-steering :
If the VSC system determines that the under-steering is large, it controls the engine power and activates the rear wheel
brakes to reduce the under-steering.
VSC indicator light
If an mulfunction occurs in the VSC system, the VSC indicator lights up to warn the driver.
4. Mutual System Control
To efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlled
while the VSC system is being operated.
Engine control
The engine power does not interfere with the VSC brake control by fuel cut controlling and reducing the engine output.
Engine control and electronically controlled transmission control
The strong braking force does not interfere with the braking force control of the VSC system by turning off the accel and
reducing changes in the driving torque at shift-down.
VSC system operation indication
The slip indicator light flashes and the buzzer alarm intermittently to warn the driver that the current road is slippery, while the
VSC system is being operated.
5. Fail Safe Function
If an mulfunction occurs in the skid control ECU with actuator, sensor signals, and/or actuators, the skid control ECU with
actuator inhibits the brake actuator control and inputs the mulfunction signal to the engine control module. According to the
mulfunction signal, the brake actuator turns off the solenoid and the engine control module rejects any electronically
controlled request from the VSC system. As a result, the vehicle functions without the ABS, BA, TRAC, and VSC systems.

Wireless Door Lock Control
In this system, the wireless door lock ECU receivers weak radio wave transmitted from the transmitter and outputs a signal
to the body ECU. Accordingly, all the doors are can be locked and unlocked by remote control.
1. Normal Operation
*Lock operation
When the lock SW on the transmitter is pressed, all the doors are locked.
*Unlock operation
When the unlock SW on the transmitter is pressed once, only the driver door is unlocked. When the unlock SW is pressed
again within 3 seconds, all the doors are unlocked.
2. Auto Lock Function
After all the doors are unlocked by pushing the UNLOCK SW of the transmitter, unless each of the doors is opened or the
ignition key is inserted, all the doors are locked again.
3. Wireless Door Lock Stop Function
If any of the following conditions are detected, the wireless door lock does not function.
Lock operation
*When any door is open (Door courtesy SW on)
*The ignition key is inserted into the ignition SW (Unlock warning SW on)
*Ignition SW is on
Unlock operation
*Ignition SW is on
4. Visual Confirmation of Lock or Unlock
When doors are locked by using the transmitter, the hazard light flashes once. When doors are unlocked by using the
transmitter, the hazard light flashes twice. If UNLOCK SW of the transmitter is pushed while all the doors are locked, doors
are unlocked and the interior light and ignition key cylinder light are turned on simultaneously.
5. Panic Mode Function
When the panic SW on the transmitter is pressed, the panic mode is activated. The panic mode is canceled when the unlock
SW or panic SW is pressed.
6. Repeat Function
If the lock detection signal in response to the output signal is not received after the wireless door lock ECU has output the
lock signal, the lock signal is output again.

1. Seat Belt Warning System
When the ignition SW is turned to the ON position, the signal is input to the body ECU. At this time, to judge whether or not
the driver fastens the seat belt, the signal from the buckle SW LH is input to TERMINAL (A) 10 of the body ECU via multiplex
commnunication system (Bean bus). If the driver does not fasten the seat belt, the seat belt warning light in the combination
meter flashes and the alarm buzzer goes on, in response to the communication control of the body ECU etc.
Additionally, the sensor (Inside of buckle SW (Front passenger's side) ) installed on the front passenger seat detects the
passenger and determines whether or not the passenger fastens the seat belt.
If the passenger does not fasten the seat belt, the front passenger seat belt warning light is flashed.
2. Key Reminder System
If the driver door is opened with the ignition SW set at the ACC or OFF position and the ignition key remained inserted into
the key cylinder (The unlock warning SW is on), the signal from the unlock warning SW is input to TERMINAL (B) 2 of the
body ECU and the signal from the door courtesy SW LH is input to TERMINAL (C) 11 of body ECU. As a result, through
communication control of the body ECU etc. the buzzer in the combination meter goes on to warn the driver that the ignition
key is still inserted.

Using the Maintenance Log Charts
3
Miles or Months?
Toyota recommends obtaining scheduled maintenance for your vehicle every
5,000 miles or six months, whichever comes first.
For example:
•If you drive 5,000 miles in less than six months, you should obtain mainte
nance at
5,000 miles— don’t wait until six months.
•If at six months you have driven less than 5,000 miles, you should obtain
maintenance at
six months— don’t wait until 5,000 miles.
Be sure to keep an eye on your mileage so that you obtain maintenance when
recommended. If you are a lowmileage driver, mark your calendar to remind
yourself to obtain maintenance every six months.
Special Operating Conditions
In addition to standard maintenance items, the maintenance log indicates
services that should be performed on vehicles that are driven under especially
demanding conditions. These “special operating conditions” and their required
maintenance items are clearly indicated in each chart.
Note:You should perform these additional maintenance services if you drive
primarilyunder any of the special operating conditions indicated. If you drive
only occasionally under these conditions, it is not necessary to perform the
additional services.
