To deter the vehicle theft, the system
is designed to sound an alarm if any of
the front, sliding or back doors or hood
is forcibly unlocked or the battery ter-
minal is disconnected and then recon-
nected when the vehicle is locked.
The alarm blows the horn intermittently
and flashes the headlights, tail lights and
other exterior lights.SETTING THE SYSTEM1. Turn the ignition key to the “LOCK” position and remove it.
The indicator light will start flashing when
the key is removed from the ignition
switch. (See “Engine immobiliser system”
for details.)
2. Have all passengers get out of the vehicle.
3. Close the front, sliding and back doors and hood. Then lock all the doors with
the key or wireless remote control
transmitter.
The indicator light will remain on when the
front, sliding and back doors and hood are
closed and locked. As the doors are locked, the system will
give you a preparation time of 30 seconds
before the setting, during which the front,
sliding or back doors and hood may be
opened.
Be careful not to unlock any door with the
key or wireless remote control transmitter
during setting. This will cancel the system.
4. After making sure the indicator light starts flashing, you may leave the ve-
hicle.
The system will automatically be set after
the preparation time passes. The indicator
light will flash to show the system is set.
If any of the front, sliding or back doors
or hood is open at that time, the setting
is interrupted until it is closed and locked.
Never leave anyone in the vehicle when
you set the system, because unlocking
from the inside will activate the system.

them when the defogger switch is on.
Make sure you turn the defoggers off
when the surfaces are clear. Leaving the
defoggers on for a long time could cause
the battery to discharge, especially during

ly coated with ice, use a spray deicer
before operating the switch.

means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after the
several trips, contact your Toyota dealer
as soon as possible.

possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” in Section 6. (f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.

ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(g) Low Engine Oil Pressure Warning
Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
