ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.

drive belt is broken or loose.
(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the ªONº position and
goes off after the engine starts. This
means that the warning light system is
operating properly.

comes on while driving, first check the
followings.

Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.

Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota dealer
as soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...

There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to ªACCº or
ªLOCKº position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions inspection and maintenance
(I/M) programs
We recommend you to contact your
Toyota dealer to check your vehicle's
emission control system and OBD
(On±Board Diagnostics) system before
taking your vehicle for a state emission
inspection.

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 ªProgramming an entrance gate/pro-
gramming all devices in the Canadian
marketº.

 buttons
you want to program. Push and hold
down one of the buttons until the indi-
cator corresponding to the selected
channel begins to flash.

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 ªProgramming
the HomeLink
º.
(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.
