Important information about your Toyota
Occupant restraint systems
Toyota encourages you and your family to take the time to
read Section 1−3 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 1 −3 of this Owner ’s Manual is
the most important Section for you and your family to
read.
Section 1 −3 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 about
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.

When you operate any switch, push it
slowly and securely.
The wireless remote control transmitter is
an electronic component. Observe the fol-
lowing instructions in order not to cause
damage to the transmitter.

Do not disassemble it.
Avoid knocking it hard against other
objects or dropping it.
Avoid putting it in water.
You can use up to 4 wireless remote con-
trol transmitters for the same vehicle.
Contact your Toyota dealer for detailed
information. If the wireless remote control transmitter
does not actuate the doors or alarm, or
operate from a normal distance:
Check for closeness to a radio trans-
mitter such as a radio station or an
airport which can interfere with normal
operation of the transmitter.
The battery may have been consumed.
Check the battery in the transmitter. To
replace the battery, see “—Replacing
transmitter battery” on page 18.
If you lose your transmitter, contact your
Toyota dealer as soon as possible to
avoid the possibility of theft, or an acci-
dent. (See “If you lose your wireless re-
mote control transmitter” on page 248 in
Section 4.)
This complies with Part 15 of the FCC
rules. Operation is subject to the follow-
ing two conditions:
(1) This device may not cause harmful
interference, and (2) this device must
accept any interference received, includ-
ing interference that may cause unde-
