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.

CAUTION
Before driving, be sure that the doors
are closed and locked, especially
when small children are in the ve-
hicle. Along with the proper use of
seat belts, locking the doors helps
prevent the driver and passengers
from being thrown out from the ve-
hicle during an accident. It also helps
prevent the doors from being opened
unintentionally.
Locking operation
Unlocking operation
The wireless remote control system is
designed to lock or unlock all the
doors or activate the “PANIC” mode
from a distance within approximately 1
m (3 ft.) of the vehicle.
LOCKING AND UNLOCKING THE
DOORS
To lock and unlock all the doors, push
the switches of the transmitter slowly
and securely.
To lock: Push the “LOCK” switch. All the

locked.
If any door is not securely closed, locking
cannot be performed by the “LOCK”
switch.
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, the
turn signal lights will flash twice.

NOTICE
 Make sure the positive side and
negative side of the transmitter bat-
tery are faced correctly.

nents inside of the transmitter, or
it may interfere with proper opera-
tion.

of the transmitter battery insertion
and that dust or oils do not adhere

light will start to flash. 5. Make sure that the indicator light
flashes. Then you may leave the ve-
hicle.
Never leave anyone in the vehicle when

vehicle, it sounds the alarm for one
minute while flashing headlights and
turn signal lights.
At this time, the interior light also turns
on when the interior light dial is in the
DOOR position. (See “Interior/instrument
panel light control” on page 79 in Section
1 −5.)
The system detects a threat under any of
the following conditions:
Either of the front doors is unlocked by
means other than the key or wireless
remote control transmitter.
If the key is not in the ignition switch,
all the doors will be automatically
locked again.
Any of the doors or trunk lid are forci-
bly opened.
The alarm will activate when the trunk
lid is opened with a key. Cancel the
system before o pening the trunk lid.

2. In front of the vehicle, pull up theauxiliary catch l ever and lift the
hood.3. Hold the hood open by inserting the support rod into the slot.
To insert the support rod into the slot,
move it straight up. If it is moved to the

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.
NOTICE
Be sure to return the support rod to
its clip before closing the hood. Clos-
ing the hood with the support rod up
could cause the hood to bend.
