■
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 lamp 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.■
SRS warning light
This warning light system monitors the airb ag sensor assembly, front airbag sensors,
side and curtain shield airbag sensors, curtain shield and rear side airbag sensors,
door sensors, driver's seat position sensor, driver's seat belt buckle switch, front
passenger occupant classification system (ECU and sensors), “AIR BAG ON” indi-
cator light, “AIR BAG OFF” in dicator light, front pass enger's seat belt buckle
switch, seat belt pretensioner assemblies, inflators, interconnecting wiring and
power sources. (  P. 1 1 9 )■
Front passenger detection sensor, passen ger seat belt reminder and warning
buzzer ●
If luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash and the warning buzzer to sound
even if a passenger is not sitting in the seat.●
If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.■
Electric power steering system warning light (warning buzzer)
When the battery charge becomes insuffic ient or the voltage temporarily drops,
the electric power steering system warn ing light may come on and the warning
buzzer may sound.
■
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 vehicl e 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 driv er's responsibility to maintain correct tire
pressure, even if under-inflation has not reached 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.
TPMS (tire pressure warning system) malfunctions may occur for a variety of rea-
sons, including the installation of replacem ent or alternate tires or wheels on the
vehicle that prevent the TPMS (tire pres sure warning system) from functioning
properly. Always check the TPMS (tire pressure warning system) malfunction tell-
tale after replacing one or more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS (tire pressure warning
system) to continue to function properly.

7645-2. Steps to take in an emergency
Indicates that the engine
has overheated
A buzzer also sounds. Stop and check.
(  P. 7 9 9 )
Indicates that remaining
fuel is approximately 2.8
gal. (10.7 L, 2.3 Imp. gal.)
or less Refuel the vehicle.
(Flashes) Indicates that the
“ENGINE START STOP”
switch is turned off or
turned to ACCESSORY
mode and the driver's
door is opened while the
lights are turned on. Turn the lights off.
(If equipped) Indicates that the Blind
Spot Monitor sensors or
the surrounding area on
the bumper is dirty or
covered with ice. Clean the sensor and its
surrounding area on the
bumper.Wa r n i n g m e s s a g e Details Correction procedure

When trouble arises
7895-2. Steps to take in an emergency
If the engine will not start If the engine will not start even though correct starting procedures are
being followed (
 P. 165), consider each of the following points.
■ The engine will not start, even th ough the starter motor operates
normally.
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 following correct starting proce-
dures. (  P. 165)
● There may be a malfunction in the engine immobilizer system.
(  P. 1 1 0 )
■ The starter motor turns over slow ly, the interior lights and head-
lights are dim, or the horn does not sound or sounds at a low vol-
ume.
One of the following may be the cause of the problem:
● The battery may be discharged. (  P. 7 9 6 )
● The battery terminal connections may be loose or corroded.
■ The starter motor does not turn over.
The engine starting system may be malfunctioning due to an electri-
cal problem such as an open ci rcuit or a blown fuse. However, an
interim measure is available to start the engine. (  P. 790)

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 explained here as an example):
• The 0W in 0W-20 indicates the characteristic 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 vi scosity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher valu e) may be better suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.
How to read oil container label:
The International Lubricant Specification Advisory Committee
(ILSAC) Certification Mark is added to some oil containers to help
you select the oil you should use. Outside temperature
