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 can be enhanced when it is used properly
and together with other systems. No single occupant re-
straint 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.

Locking operation
Unlocking operation
The wireless remote control system is
designed to lock or unlock all the side
doors and back door, 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 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 igni-
tion, a beep will not sound.
To stop the beep, close all the side doors
and back door securely or push the
“UNLOCK” switch.
The beep 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 all the side doors and back door
are unlocked simultaneously with a wire-
less remote control transmitter, the center
interior light, personal lights and ignition
switch light come on for about 15 seconds
before fading out, even if the door is not
opened. (For details, see “Interior lights”
on page 118, “Personal lights” on page
119 and “Ignition switch light” on page 120
in Section 1−
5.)
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. At this time, one beep
will be heard, and the turn signal lights
flash once.

2. To remove the fuel tank cap, turn
the cap counterclockwise by 90 de-
grees (to the pressure point 1), and
then turn it an additional 30 degrees
(to point 2). Pause slightly before
removing it.
It is not unusual to hear a slight swoosh
when the cap is opened.3. The removed cap can be stored on the back side of the fuel filler door.
Position the cap so that the hooks point
to the left and right, and set it in the
receptacle on the back side of the door. When installing the cap, turn the cap
clockwise until you hear a click. When
you hear the click, the cap is fully
closed.

several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

curely to prevent fuel sp
illage in
the event of an accident.

cap for replacement. It is designed
to regulate fuel tank pressure.

CAUTION
To reduce the risk of sliding under
the lap belt during a collision, avoid
reclining the seatback any more than
needed. The seat belts provide maxi-
mum protection in a frontal or rear
collision when the driver and the
front passenger are sitting up straight
and well back in the seats. If you are
reclined, the lap belt may slide past
your hips and apply restraint forces
directly to the abdomen. In the event
of a frontal collision, the more the
seat is reclined, the greater the risk
of personal injury.
3. SEAT LUMBAR SUPPORT
ADJUSTING SWITCH
Press either side of the switch.
The amount of lumber support will change
while the switch is pressed.
CAUTION
Do not adjust the seat while the
vehicle is moving.
Be careful that the seat does not
hit a passenger or luggage.
Be careful not to get your hands or
feet pinched in the seat.
After adjusting the seat position, re-
lease the lever and try sliding the
seat forward and backward to make
sure it is locked in position.
After adjusting the seatback, push
your body back against the seat to
make sure the seat is locked in
position.
When returning the seatback to the
upright position, observe the follow-
ing precautions in order to prevent
personal injury in a collision or
sudden stop:
Make sure the seatback is securely
locked by pushing forward and rear-
ward on the top of the seatback.
Failure to do so will prevent the
seat belt from operating properly.
Make sure the seat belts are not
twisted or caught in the seatback
and are arranged in their proper
position and are ready to use.
Folding down the rear seatbacks will en-
large the luggage compartment. See
“—Stowage precautions” on page 305 in
Section 2 for precautions when loading
luggage.
