(e) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the nearest Lexus dealer or
repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(f) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pressure 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 Lexus
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 oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on ± evenfor one block. It may ruin the engine.

GARAGE DOOR OPENER
The garage door opener (HomeLink 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
SV14007

1Buttons 2Indicator light
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
programming. The battery side of the hand± held transmitter must be pointed
away from the HomeLink
 during the programming process.
For Canadian users, follow the procedure in ºProgramming an
entrance gate/Programming all devices in the Canadian
marketº.
1. Decide which of 3 HomeLink
 buttons you want to
program.
2. Place your hand± held garage transmitter 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 hand± held garage
transmitter button along with the selected HomeLink
 button.
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, identify if your garage
transmitter is of the ºRolling Codeº type. Press and hold the
programmed HomeLink
 button. The garage 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 ºRolling Codeº type, proceed to the
heading ºProgramming a rolling code systemº.
6. Repeat steps 2 through 5 for each remaining HomeLink

button to program another device.
