7-2. Steps to take in an emergency
Fuel pump shut off system (gasoline vehicles)
Follow the procedure below to restart the engine after the system is acti-
vated.Turn the “START STOP ENGINE” switch to ACCESSORY mode or
turn it off.
Restart the engine.
To minimize the risk of fuel leakage when the engine stalls or when an
airbag inflates upon coll ision, the fuel pump shut off system stops the
supply of fuel to the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.

After taking the specified steps to correct the suspected problem, check
that the warning light goes off.
Follow the correction procedures.
Warning lightWarning light/DetailsCorrection procedure
Open door warning light
(warning buzzer)
*1
Indicates that a door or the
trunk is not fully closed
Check that all the doors and
the trunk are closed.
Low fuel level warning lightIndicates remaining fuel is
approximately 2.6 gal. (9.7 L,
2.1 Imp.gal.)
Refuel the vehicle.
Seat belt reminder light (warn-
ing buzzer)
*2
Warns the driver and/or front
passenger to fasten their seat
belts
Fasten the seat belt.If the front passenger’s seat is
occupied, the front passen-
ger’s seat belt also needs to
be fastened to make the
warning light (warning
buzzer) off.
Master warning lightA buzzer sounds and the
warning light comes on and
flashes to indicate that the
master warning system has
detected a malfunction.

■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 (ECU and sensors), “AIR BAG ON” indicator light,
“AIR BAG OFF” indicator light, front passenger’s seat belt buckle switch, seat belt
pretensioner assemblies, airbags, interconnecting wiring and power sources.
(→ P. 4 0 )
■Front passenger detection sensor, seat belt reminder and warning buzzer
●If luggage is placed on the front passenger 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 a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
■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.
■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.

When trouble arises
CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure 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 [tire 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 warning 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 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 the 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 (gasoline vehicles)
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 procedures.
(→P. 1 9 7 )
●There may be a malfunction in the engine immobilizer system.
(→P. 8 0 )
One of the following may be the cause of the problem:
●The 12-volt battery may be discharged. ( →P. 805)
●The 12-volt 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 9 8 )
If the engine will not start even though correct starting procedures are
being followed ( →P. 197), 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.

such as electronic key battery depletion or a blown fuse. However,
depending on the type of malfunction, an interim measure is available
to start the hybrid system. ( →P. 8 0 0 )
One of the following may be the cause of the problem:
●The 12-volt battery may be discharged. ( →P. 8 0 9 )
