Locking operation
Unlocking operation
The wireless remote control system is
designed to lock or unlock all the side
doors and back door, open the back
window or activate the “PANIC” mode
from a distance within approximately 1
m (3 ft.) of the vehicle.
LOCKING AND UNLOCKING THE SIDE
DOORS AND BACK DOOR
To lock and unlock all the side doors
and back door, push the switches of
the transmitter slowly and securely.
To lock: Push the “LOCK” switch. All the
side doors and back door are locked si-
multaneously. At this time one beep will
be heard, and the turn signal lights flash
once.
Check to see that all the side doors and
back door are securely locked.
If any of the side doors or the back door
is not securely closed, locking cannot be
performed by the “LOCK” switch and a
beep will sound continuously for 10 sec-
onds. However, if the key is in the ignition
switch, a beep will not sound.
To stop the buzzer, close all the side
doors and back door securely or push the
“UNLOCK” switch.
The buzzer can be disabled. For details,
contact your Toyota dealer. To unlock: Push the “UNLOCK” switch
once to unlock the driver ’s door alone.
Pushing the switch twice within 3 seconds
unlocks all the side doors and back door
simultaneously. Each time the “UNLOCK”
switch is pushed, two beeps will be heard,
and the turn signal lights flash twice.
This double switch operation to unlock all
the side doors and back door can be
changed to a single switch operation. For
details, contact your Toyota dealer.
When the “UNLOCK” switch is pressed,
the interior light, luggage compartment
light, ignition switch light and running
board lights (on some models) will come
on and remain on for about 15 seconds
before fading out. (For details, see “Interi-
or light” on page 105, “Luggage compart-
ment light” on page 107, “Ignition switch
light” on page 108 and “Running board
lights” on page 108 in Section 14.)
You have 30 seconds to open a door after
using the wireless remote unlock feature.
If a door is not opened by then, all the
side doors and back door will be automati-
cally locked again.
The timing for the automatic door lock
function can be changed. For details, con-
tact your Toyota dealer.

When all the side doors and back door
are unlocked simultaneously with a key,
the interior light, luggage compartment
light, ignition switch light and running
board lights (on some models) will come
on and remain on for about 15 seconds
before fading out. (For details, see “Interi-
or light” on page 105, “Luggage compart-
ment light” on page 107, “Ignition switch
light” on page 108 and “Running board
lights” on page 108 in Section 14.)
The back window can be opened and
closed with the key operation in the back
door keyhole. (For details, see “Power
back window” on page 26 in this Section.)
When closing the back door, the inside
strap can be used to make the reach
easier.
To close the back door, lower it and press
down on it. After closing the back door,
try pulling it up to make sure it is secure-
ly closed.
Back door closer: When the back door
has not been fully closed, it is automati-
cally closed completely.
See “Luggage stowage precautions” on
page 253 in Section 2 for precautions
when loading luggage.
CAUTION
Keep the back window and back
door closed while driving. This not
only keeps the luggage from being
thrown out but also prevents ex-
haust gases from entering the ve-
hicle.
Careful attention is needed so as
not to get your fingers trapped as
the back door automatically closes
when it has not been fully closed.
Never allow a child to operate the
back door.
NOTICE
 To avoid damage to the back door
dampers, do not apply any force,
paint or let any other foreign matter
on them.
 Do not apply excessive force when
the back door closer is operating.
Otherwise, the back door closer
may become defective.

and flashes the headlights, tail lights and
turn signal lights, and turns on the interior
and luggage compartment lights.
