5-1. Essential information
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked on to the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine. Have the vehi-
cle checked and repaired by your Toyota dealer.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fuel pump shut off system stops sup-
plying fuel to the engine.

■ 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.

If the malfunction indicator lamp does not go off even after several trips, con-
tact your Toyota dealer as soon as possible.

422 5-2. Steps to take in an emergency
CAUTION
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressu re telltale (tire pressure warning light) illumi-
nates, 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 effi ciency and tire tread life, and may
affect the vehicle's hand ling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper ti re maintenance, an d it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination 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 indi cate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator 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 vari-
ety of reasons, including the installati on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.

If the engine still does not start after following the correct starting
procedure ( P. 118) or releasing the steering lock ( P. 120), confirm

procedures. ( P. 1 1 8 )
● There may be a malfunction in the engine immobilizer system.
(  P. 6 8 )
■ The starter motor turns over slowly, the interior lights and
headlights are dim, or the horn does not sound or sounds at
a low volume.
One of the following may be the cause of the problem.
●The battery may be discharged. ( P. 441)
● The battery terminal connec tions may be loose or corroded.
■ The starter motor does not turn over, the interior lights and
