■SRS warning light
This warning light system monitors the airbag sensor assembly, front impact sensors,
side impact sensors (front door), side impact sensors (front), side impact sensors
(rear), driver’s seat position sensor, driver’s seat belt buckle switch, front passenger
occupant classification system, “AIR BAG ON” indicator light, “AIR BAG OFF” indi-
cator light, front passenger’s seat belt buckle switch, seat belt pretensioner assem-
blies, inflators, interconnectin g wiring and power sources. ( P. 38)
■Front passenger detection sensor, seat belt reminder and warning buzzer
If luggage is placed on the front passen ger seat, the front passenger detection sen-
sor may cause the warning light to flash and the warning buzzer to sound even if a
passenger is not sitting in the seat.
■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.
■Changing the engine oil (U.S.A. only)
Make sure to reset th e oil change system. ( P. 6 0 2 )
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch will not turn off the tire pressure warning light.

CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure re commended by the vehicle manufacturer on
the vehicle placard or tire inflation pressu re label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [t ire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS-tire pressure wa rning system) that illuminates a low tire
pressure telltale (tire pressure warning light ) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not re ached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system)
malfunction indicator to indicate when th e system is not operating properly. The
TPMS (tire pressure warning system) malfunction indicator is combined with the
low tire pressure telltale (tire pressure warning light). When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists . When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure as intended.

When trouble arises
7-2. Steps to take in an emergency
If the engine will not start
One of the following may be the cause of the problem:
●There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
●The engine may be flooded.
Try to restart the engine again foll owing correct starting procedures.
( P. 1 5 4 )
●There may be a malfunction in the engine immobilizer system.
( P. 6 8 )
One of the following may be the cause of the problem:
●The battery may be discharged. ( P. 743)
●The battery terminal connections may be loose or corroded.
The engine starting system may be malfunctioning due to an electrical
problem such as electronic key battery depletion or a blown fuse. How-
ever, an interim measure is available to start the engine. ( P. 7 3 6 )
If the engine will not start even though correct starting procedures are
being followed ( P. 154), consider each of the following points:
The engine will not start even though the starter motor operates
normally.
The starter motor turns over slowly, the interior lights and head-
lights are dim, or the horn does not sound or sounds at a low vol-
ume.
The starter motor does not turn over

Vehicle specifications
■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the fol-
lowing grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.
Oil viscosity (0W-20 is expl ained here as an example):
• The 0W in 0W-20 indicates the ch aracteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the visc osity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity (one
with a higher value) may be better su ited if the vehicle is operated at
high speeds, or under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) Certifica-
tion Mark is added to some oil
containers to help you select the
oil you should use.
