2. Remove the discharged battery.
3. Put a new battery with the positive (+)
side up.
Put in the case securely.
NOTICE
Make sure that the positive side of
the controller battery is facing cor-
rectly.
 Do not replace the battery with wet
hands. Water may cause rust.
 Do not touch or move any compo-
nents inside of the controller, or it
may interfere with proper operation.
 Be careful not to bend the electrode
of the controller battery insertion
and that dust or oil does not ad-
here to the transmitter case.
 Close the battery case securely.
After replacing the battery, check that the
controller operates properly. If the control-
ler still does not operate properly, contact
your Toyota dealer.
NOTICE
To ensure correct audio system op-
erations:
Be careful not to spill beverages
over the audio system.
 Do not put anything other than a
cassette tape or compact disc into
the slot.
 The use of a cellular phone inside
or near the vehicle may cause a
noise from the speakers of the au-
dio system. This does not indicate
a malfunction.
RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radio—it is just the normal result of
conditions outside the vehicle.
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.

CAUTION
When doing the circling calibration,
be sure to secure a wide space,
and watch out for people and ve-
hicles in the neighborhood. Do not
violate any local traffic rules while
performing circling calibration.
Do not adjust the display while the
vehicle is moving. Be sure to adjust
the display only when the vehicle is
stopped.
The rear view monitor system assists
the driver by displaying images of the
rear of the vehicle during backing up.
The displayed image on the screen is
a horizontally reversed mirror image of
the inside rear view mirror.
To display the rear view on the screen,
place the selector lever in the “R” posi-
tion when the ignition switch in the
“ON” position.
If you move the selector lever out of the
“R” position, the screen returns to the
previous screen. Operating another func-
tion of the navigation system will display
another screen.
The rear view monitor system is an auxil-
iary device intended to back up. When
backing up, be sure to check behind and
all around the vehicle visually.
CAUTION
Do not rely entirely on the rear
view monitor system.
Use caution just as you would when
backing up any vehicle.
Never back up while looking only at
the screen. The image on the
screen may differ from actual con-
ditions. If you back up while look-
ing only at the screen, you may hit
a vehicle or have an unexpected
accident. When backing up, be sure
to check behind and all around the
vehicle visually and with mirrors
before proceeding.
NOTICE
Do not use the system when the
back door is not completely closed.
 If the back of the vehicle is hit, the
position and mounting angle of the
camera may slip. Be sure to have
the camera’s position and mounting
angle checked at your Toyota deal-
er.
 If the temperature changes rapidly,
such as when hot water is poured
on it in cold weather, the system
may not operate normally.

THE REAR VIEW MONITOR SYSTEM
CAMERA
The rear view monitor system camera
is located on the back door as shown
in the illustration.
The rear view monitor system camera
uses a special lens. The distance of
the images that appear on the screen
differs from the actual distance.
In the following cases, it may become
difficult to see the images on the
screen, but this is not a malfunction.
In the dark (for example, at night)
When the temperature near the lens is
high or low When water droplets are adhering to
the camera, or when humidity is high
(for example, when it rains)
When foreign matter (for example,
mud) is adhering to the camera
When the sun or the beam of head-
lights is shining directly into the cam-
era lens
If a bright light (for example, sunlight
reflected off the vehicle body) is picked
up by the camera, the smear effect
∗
peculiar to the CCD camera may occur.
∗: Smear effect—A phenomenon that oc-
curs when a bright light (for example, sun-
light reflected off the vehicle body) is
picked up by the camera; when trans-
mitted by the camera, the light source
appears to have a vertical streak above
and below it.

On some models, an auxiliary box is
located inside the glove box.
To increase the capacity of the glove box,
raise the lower panel of the auxiliary box.
The garage door opener (
Universal Transceiver) is manufactured
under license from HomeLink and can
be programmed to operate garage
doors, gates, entry doors, door locks,
home lighting systems, and security
systems, etc. (a) Programming the HomeLink

The HomeLink in your vehicle has 3
buttons and you can store one program
for each button.
To ensure correct programming into the
HomeLink
, install a new battery in the
hand− held transmitter prior to program-
ming.
The battery side of the hand −held trans-
mitter must be pointed away from the
HomeLink
 during the programming pro-
cess.
For Canadian users, follow the procedure
in “Programming an entrance gate/pro-
gramming all devices in the Canadian
market”.
1. Decide which of 3 HomeLink
 buttons
you want to program.
2. Place your hand− held garage transmit-
ter 25 to 75 mm (1 to 3 in.) away from
the surface of the HomeLink
.
Keep the indicator light on the HomeLink

in view while programming.

6. Test the operation of the HomeLink by
pressing the newly programmed button.
Check to see if the gate/device oper-
ates correctly.
7. Repeat steps 1 through 6 for each re- maining HomeLink
 button to program
another device.
Programming other devices
To program other devices such as home
security systems, home door locks or
lighting, contact your authorized Toyota
dealer for assistance.
Reprogramming a button
Individual HomeLink
 buttons cannot be
erased, however, to reprogram a single
button, follow the procedure “Programming
the HomeLink
”.
(b) Operating the HomeLink

To operate the HomeLink, press the
appropriate HomeLink button to activate
the programmed device. The HomeLink
indicator light should come on. The
HomeLink continues to send the signal
for up to 20 seconds as long as the
button is pressed. (c) Erasing the entire HomeLink

memory (all three programs)
To erase all previously programmed codes
at one time, press and hold down the 2
outside buttons for 20 seconds until the
indicator light flashes.
If you sell your vehicle, be sure to erase
the programs stored in the HomeLink

memory.
CAUTION
When programming the HomeLink
Universal Transceiver, you may be
operating a garage door or other
device. Make sure people and ob-
jects are out of the way of the ga-
rage door or other device to pre-
vent potential harm or damage.
Do not use this HomeLink Univer-
sal Transceiver with any garage
door opener that lacks the safety
stop and reverse feature as re-
quired by federal safety standards.
(This includes any garage door
opener model manufactured before
April 1, 1982.) A garage door open-
er which cannot detect an object
(signaling the door to stop and re-
verse), does not meet current feder-
al safety standards. Using a garage
door opener without these features
increases risk of serious injury or
death.

If the trash holder is pulled strongly or
stepped on, it will detach from the rear
console box to protect it from damag-
ing.
If the trash holder becomes detached, re-
install it in a horizontal direction as indi-
cated in the illustration. It cannot be
installed in any other direction.
NOTICE
Do not deliberately pull or step on
the trash holder, as it may be dam-
aged or broken.
The cup holders are designed for hold-
ing cups or drinkcans securely.
The cup holder can be adjustable to the
size of the cups or drinkcans by
changing the holder position and the
arm position, as shown.
With the instrument panel lights on, the
front cup holder position indicator lights
will come on.
CAUTION
Do not place anything else other than
cups or drinkcans in the cup holder,
as such items may be thrown about
in the compartment and possibly in-
jured people in the vehicle during
sudden braking or in an accident.
