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.

The compass may not show the correct
direction in the following conditions:
The vehicle is stopped immediately af-
ter turning.
The compass does not adjust while the
vehicle is stopped.
The ignition switch is turned off imme-
diately after turning.
The vehicle is on an inclined surface.
The vehicle is in a place where the
earth’s magnetic field is subject to in-
terference by artificial magnetic fields
(underground parking, under a steel
tower, between buildings, roof parking,
near a crossing, near a large vehicle,
etc.).
The vehicle is magnetized. (There is a
magnet or a metal object on or near
the inside rear view mirror.)
The battery has been disconnected.
Your vehicle is out of the set zone. Refer
to the “CALIBRATING THE COMPASS” be-
low to set the zone number.
The compass works to calibrate the direc-
tion automatically while the vehicle is in
motion, if deviation is small.
For additional precision or for complete
calibrating, see “CALIBRATING THE
COMPASS” below.
Compass sensor
The compass sensor is on the wind-
shield.
NOTICE
Do not put magnets or a metal object

CALIBRATING THE COMPASS (circling
calibration)
Sometimes the direction display on the
compass may not change after a turn. To
rectify this, stop the vehicle and push and
hold the “COMP” switch until “C” appears
on the display.
If “C” appears on the display because of
a drastic change in the magnetic field,
perform circling calibration.Drive the vehicle in a circle at 8 km/h (5
mph) or less. If there is not enough space
to drive in a circle, drive around the
block.
After driving 1 to 3 circles in the above
method, calibration is completed when the
direction is shown on the display.
If calibration cannot be performed because
of the magnetized vehicle etc., take your
vehicle to Toyota dealer. Perform circling calibration just after
you have purchased your Toyota. And
then always perform circling calibration
after the battery has been removed, re-
placed or disconnected.
Do not perform circling calibration of
the compass in a place where the
earth’s magnetic field is subject to in-
terference by artificial magnetic fields
(underground parking, under a steel
tower, between buildings, roof parking,
near a crossing, near a large vehicle,
etc.).
During calibration, do not operate elec-
tric systems (moon roof, power win-
dows, etc.) as they may interfere with
the calibration.

(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
handheld transmitter prior to program-
ming.
The battery side of the handheld 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 handheld 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. 3. Simultaneously press and hold the
handheld garage transmitter button
along with the selected HomeLink
 but-
ton.
4. When the indicator light on the HomeLink
 changes from a slow to a
rapid flash after 20 seconds, you can
release both buttons.
5. Test the operation of the HomeLink
 by
pressing the newly programmed button.
If programming a garage door opener,
check to see if the garage door opens
and closes.
If the garage door does not operate, iden-
tify if your garage transmitter is of the
“Rolling C ode” type. Press and hold the
programmed HomeLink
 button. The ga-
rage door has the rolling code feature if
the indicator light (on the HomeLink
)
flashes rapidly and then remains lit after
2 seconds. If your garage transmitter is
the “Rolling Code” type, proceed to the
heading “Programming a rolling code sys-
tem”.
6. Repeat steps 2 through 5 for each re- maining HomeLink
 button to program
another device. Programming a rolling code system
If your device is “Rolling Code”
equipped, it is necessary to follow
steps 1 through 4 under the heading
“Programming the HomeLink
” before
proceeding with the steps listed below.
1. Locate the “training” button on the ceil- ing mounted garage door opener motor.

NOTICE
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.
 Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil’s lubricating qualities.
 Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
Always perform a maintenance in-
spection after each day of offroad
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the “Scheduled Main-
tenance Guide” or “Owner’s Manual
Supplement”.Make sure your coolant is properly pro-
tected against freezing.
Your coolant must contain ethyleneglycol
type coolant for a proper corrosion protec-
tion of aluminum components. Use “Toyota
Genuine Long Life Coolant” or equivalent.
See page 326 in Section 72 for details
about coolant type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about 50 C
(58 F). Do not use more than 70% solu-
tion for better coolant performance.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 73 tells you how to visually
inspect the battery. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.
