(n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to ONº
and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to ONº position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to ONº position. The light will remain on
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible.
You need to reset the light after the engine oil replacement.
Reset the light by following the procedure below:
1. Turn the ignition key to the ACCº or LOCKº position with
the odometer reading shown. (For details, see Odometer and
trip meterº on page 61.)
2. Turn the ignition key to the ONº position while holding down
the trip meter reset knob.
Hold down the knob until the light goes off. Before the light
goes off, it illuminates for 3 seconds, flashes for 2 seconds and
illuminates for 1 second. If the system fails to reset, the light will remain flashing. In this
case, return to step 1 and try again.(o) Low Tire Pressure Warning Light
This light warns that the tire pressure of one or more of your
tires
(including the spare tire) is low. The light comes on when
the ignition key is turned to the ONº position. It goes off after
a few seconds. This indicates that the tire pressure warning
system is functioning properly.
If the warning light comes on, stop your vehicle in a safe place
as soon as possible and check that the inflation pressure of all
tires (including the spare tire) is as specified on the tire and
loading information label. (See Checking tire inflation
pressureº on page 578.) The light should go off a few minutes
after the tire pressure is adjusted.
If the warning light blinks, the tire pressure warning system
may be malfunctioning. Contact your Lexus dealer.
For details, see Tire pressure warning systemº on page 433.
(p) Low Fuel Level Warning Light
This light comes on when the fuel level in the tank becomes
very low. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.

(c) Erasing the entire HomeLink memory (all
three programs)

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

Be careful not to damage the belt webbing or
hardware. Take care that they do not get caught or
pinched in the seat or doors.
 Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.
 Keep the belts clean and dry. If they need cleaning,
use a mild soap solution or lukewarm water. Never
use bleach, dye, or abrasive cleaners, or allow them
to come into contact with the belt Ð they may
severely weaken the belts. (See Cleaning the
interiorº on page 636 for instructions.)
 Replace the belt assembly (including bolts) if it has
been used in a severe impact. The entire assembly
should be replaced even if damage is not obvious.

CAUTION
Do not modify, remove, strike or open the seat belt
pretensioner assemblies, airbag sensor or
surrounding area or wiring. Failure to follow these
instruction may prevent the seat belt pretensioners
from activating correctly, cause sudden operation of
the system or disable the system, which could result
in death or serious injury. Consult your Lexus dealer
about any repairs and modifications.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, which could result in death or
serious injury. Consult your Lexus dealer about any
repair and modification.
 Do not use tires or wheels other than the
manufacture's recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, which could
result in death or serious injury. For details, see
Checking and replacing tiresº on page 593.
 Do not place luggage heavier than specified on the
roof luggage carrier. Such luggage may cause the
curtain shield airbags and seat belt pretensioners to
inflate accidentally, which could result in death or
serious injury. For details, see Roof luggage
carrierº on page 119.

vehicle tip-up is marginal or if the skidding vehicle's tires
hit a curb stone laterally as shown in the illustration.

1Collision from the front
2Collision from the rear
3Pitching end over end

Do not use seat accessories which cover the parts
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or upholstery of
the seats with side airbags. Such changes may
prevent the side airbag system form activating
correctly, disable the system or cause the side
airbags to inflate accidentally, resulting in death or
serious injury.
 Do not disassemble or repair the front and rear pillars
and roof side rails containing the curtain shield
airbags. Such changes may disable the system or
cause the curtain shield airbags to inflate
accidentally, resulting in death or serious injury.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, which could result in death or
serious injury. Consult your Lexus dealer about any
repair and modification.
 Do not use tires or wheels other than the
manufacture's recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, which could
result in death or serious injury. For details, see
Checking and replacing tiresº on page 593.
