Important information about your Toyota
Occupant restraint systems
Toyota encourages you and your family to take the time to
read Section 13 of this Owner ’s Manual carefully. In
terms of helping you understand how you can receive the
maximum benefit of the occupant restraint systems this
vehicle provides, Section 13 of this Owner ’s Manual is
the most important Section for you and your family to
read.
Section 13 describes the function and operation concern-
ing seats, seat belts, SRS airbags and child restraint sys-
tems of this vehicle and some potential hazards you
should be aware of. These systems work together along
with the overall structure of this vehicle in order to provide
occupant restraint in the event of a crash. The effect of
each system is enhanced when it is used properly and
together with other systems. No single occupant restraint
system can, by itself, provide you or your family with the
equal level of restraint which these systems can provide
when used together. That is why it is important for you and
your family to understand the purpose and proper use of
each of these systems and how they relate to each other.
The purpose of all occupant restraint systems is to help
reduce the possibility of death or serious injury in the
event of a collision. None of these systems, either individ-
ually or together, can ensure that there is no injury in the
event of collision. However, the more you know a bout
these systems and how to use them properly, the greater
your chances become of surviving an accident without
death or serious injury.
Seat belts provide the primary restraint to all occupants of
the vehicle, and every occupant of the vehicle should wear
seat belts properly at all times. Children should always be
secured in child restraint systems that are appropriate for
their age and size. SRS (Supplemental Restraint System)
airbags are, as their names imply, designed to work with,
and be supplemental to, seat belts and are not substitutes
for them. SRS airbags can be very effective in reducing
the risk of head and chest injuries by preventing contact of
the head and chest with interior portions of the vehicle.

The wireless remote control system is
designed to lock or unlock all the
doors, open the trunk lid, or activate
the “PANIC” mode from a distance
within approximately 1 m (3 ft.) of the
vehicle.
LOCKING AND UNLOCKING THE
DOORS

lights, side marker lights, license plate
lights and tail lights flash once.

locked.
If any of the doors is not securely closed,
or if the key is in the ignition switch,
locking cannot be performed by the
“LOCK” switch and a beep will sound con-
tinuously for 10 seconds.To unlock: Push the “UNLOCK” switch
once to unlock the driver ’s door alone.
Pushing the switch twice within 3 seconds
unlocks all the doors simultaneously. Each
time the “UNLOCK” switch is pushed, two
beeps will be heard, and the parking
lights, side marker lights, license plate
lights and tail lights flash twice.
If the ignition key is in the “ON” position,
unlocking cannot be performed by the
“UNLOCK” switch.
When all the doors are unlocked simulta-
neously with a key or wireless remote
control transmitter, the interior lights and
ignition switch light come on for about 15
seconds and then fade out, even if the
door is not opened. (For further informa-
tion, see “Interior light”, “Front personal
and interior lights” and “Ignition switch
light” in Section 15.)
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
doors will be automatically locked again.
If the “LOCK” or “UNLOCK” switch is kept
pressed in, the locking or unlocking opera-
tion is not repeated. Release the switch
and then push again.
