(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.
The engine ignition will continue to oper-
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.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance. The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
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 will not go off even after the
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, auto-
matic transmission electrical system or
warning light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 250
in Section 6.

(f) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(g) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.
CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(h) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope, the
overdrive should be turned off. Be sure
to turn the switch on immediately after-
ward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Always use the brake pedal or the
parking brake to hold the vehicle on
an upgrade. Do not attempt to hold
the vehicle using the accelerator ped-
al, as this can cause the transmission
to overheat.
(i) Driving in snow mode

tem shifts up from second gear. Use this
mode when starting your vehicle in ice or
snow.

mode, push the switch. In the “ECT

TONE AND BALANCE
For details about your system’s tone and
balance controls, see the description of
your own system.
Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange and bass levels. In
fact, different kinds of music and vocal
programs usually sound better with differ-
ent mixes of treble, midrange and bass.
Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another. YOUR RADIO ANTENNA
Mast type antenna—
To remove: Turn it counterclockwise care-
fully.
To install: Turn it clockwise securely.
NOTICE

Mast type antenna:
To prevent damage to the antenna,
make sure it is removed before
driving your Toyota through an au-
tomatic car wash.
 Onglass antenna (builtin on the
rear window glass):
Attaching the film (especially con-
ductive or metallic type) on the rear
glass will noticeably reduce the
sensitivity of the radio.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should face to the right.
NOTICE

do not insert anything other than cas-
sette tapes into the slot, or the tape
player may be damaged.
YOUR COMPACT DISC PLAYER (type 1)
When you insert a disc, gently push it in
with the label side up. (The player will
automatically eject a disc if the label side
is down.) The compact disc player will

next disc.
The changer is intended for use with 12
cm (4.7 in.) discs only.

handheld transmitter prior to program-
ming.
The battery side of the handheld trans-
mitter must be pointed away from the

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.
