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 side
doors are closed and locked, espe-
cially when small children are in the
vehicle. Along with the proper use of
seat belts, locking the side doors
helps prevent the driver and passen-
gers from being thrown out from the
vehicle during an accident. It also
helps prevent the side doors from be-
ing opened unintentionally.
Locking operation
Unlocking operation
The wireless remote control system is
designed to lock or unlock both 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 both side doors and
back door, push the switches of the
transmitter slowly and securely.
To lock: Push the “LOCK” switch. Both
side doors and back door are locked si-
multaneously. At this time, parking lights,
side marker lights and tail lights flash.
Check to see that both side doors and
back door are securely locked.
If either side doors or back door is not
securely closed, or if the key is in the
ignition switch, locking cannot be per-
formed by the “LOCK” switch.
To unlock: Push the “UNLOCK” switch
once to unlock the driver ’s door alone.

Close the transmitter case securely.
NOTICE
 Make sure the positive side and
negative side of the transmitter bat-
tery are faced correctly.
 Do not replace the battery with wet
hands. Water may cause unexpected
rust.
 Do not touch or move any compo-
nents inside of the transmitter, or
it may interfere with proper opera-
tion.
Be careful not to bend the electrode
of the transmitter battery insertion
and that dust or oils do not adhere
to the transmitter case.
 Close the transmitter case securely.
After replacing the battery, check that the
transmitter operates properly. If the trans-
mitter still does not operate properly, con-
tact your Toyota dealer.
The windows can be operated with the
switch on the center console.
The power windows work when the ignition
switch is in the “ON” position.

closed, they work for 43 seconds even
after the ignition switch is turned off. They
stop working when either side door is
opened.

CAUTION
To avoid serious personal injury, you
must do the following.
Before you close the power win-
dows, always make sure there is
nobody around the power windows.
You must also make sure the
heads, hands and other parts of the
bodies of all occupants are kept
completely inside the vehicle. If
someone’s neck, head or hands get
caught in a closing window, it
could result in a serious injury.
When anyone closes the power win-
dows, make sure he or she oper-
ates the windows safely.
When small children are in the ve-
hicle, never let them use the power
window switches without supervi-
sion. Use the window lock switch to
prevent them from making unex-
pected use of the switches.
Be sure to remove the ignition key
when you leave your vehicle.
Never leave anyone (particularly a
small child) alone in your vehicle,
especially with the ignition key still
inserted. Otherwise, he/she could
use the power window switches and
get trapped in a window. Unat-
tended person (particularly a small
child) can be involved in a serious
accident.
Insert the master key into the keyhole
and turn it.
To lock: Turn the key clockwise.
To unlock: Turn the key counterclockwise.
To open the back door, pull the lock re-
lease lever.
Operating the power door lock switch or
wireless remote control transmitter simul-
taneously locks or unlocks the back door.

3. Hold the hood open by inserting thesupport rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its
clip—this prevents rattles. Then lower the
hood and make sure it locks into place.
If necessary, press down gently on the
front edge to lock it.
CAUTION
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.

er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re-
moved.
2. To remove the fuel tank cap, turnthe cap slowly counterclockwise,
then pause slightly before removing
it. After removing the cap, hang the
tether as shown in the illustration.
It is not unusual to hear a slight swoosh
when the cap is opened. When installing,
turn the cap clockwise till you hear a
click.
If the cap is not tightened securely, the
malfunction indicator lamp comes on.
Make sure the cap is tightened securely.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.
CAUTION
Make sure the cap is tightened se-
curely to prevent fuel sp illage in
the event of an accident.
Use only a genuine Toyota fuel tank
cap for replacement. It has a built
in check valve to reduce fuel tank
pressure.
