Unlock any of side door or back door
with the key or wireless remote control
transmitter.

details, contact your Toyota dealer.For replacement, use a CR2016 lithium
battery or equivalent.

vent small children from swallowing
the removed transmitter battery or
components.

tery, be careful not to lose the com-
ponents.

3. Hold the hood open by inserting the
support rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its
clipÐthis prevents rattles. Then lower the
hood and make sure it locks into place.
If necessary, press down gently on the
front edge to lock it.
CAUTION
After inserting the support rod into
the slot, make sure the rod supports
the hood securely from falling down
on to your head or body.
To deter vehicle theft, the system is
designed to sound an alarm if any of
the side doors, back door or hood is
forcibly unlocked or the battery termi-
nal is disconnected and then recon-
nected when the system is set.
The alarm blows the horn intermittently
and flashes the headlights, tail lights and
turn signal lights, and turns on the interior
light.SETTING THE SYSTEM
1. Turn the ignition key to the LOCKº
position and remove it.
The indicator light will start flashing when
the key is removed from the ignition
switch. (See Engine immobilizer systemº
on page 17 in this Section for details.)
2. Have all passengers get out of the
vehicle.
3. Close and lock all the side doors, back
door and hood.
The indicator light will remain on when all
the side doors, back door and hood are
closed and locked.
