This child restraint is designed for use
only by children who weigh between 10
and 18 kg (22.1 and 39.5 lb.) and whose
height is between 85 and 101 cm (33.5
and 40.0 in.).
The child should be at least one year
old and must be capable of sitting up-
right alone and whose shoulder height
is at or below the maximum shoulder
height indicator. See indicator label be-
hind child seat pad.
It is important to use a rearfacing
child restraint until the child is about
a year old. A rearfacing restraint gives
the child’s head, neck and body the
support they would need in a crash.
See “—Child restraint system” for more
information.
If your child’s shoulders are above the
indicator position, do not use the built
in child restraint. Your child should use
the adult lap and shoulder belt.
According to accident statistics, children
are safer when properly restrained in the
rear seat than in the front seat.CAUTION
Make sure the child is securely re-
strained with the builtin child re-
straint. WARNING! Failure to follow
the manufacturer ’s instructions on the
use of this child restraint system can
result in your child striking the ve-
hicle’s interior during a sudden stop
or crash. Snugly adjust the belts pro-
vided with this child restraint around
your child.
When using the builtin child re-
straints, observe the following:
Use the belts of one child restraint
for only one child at a time. Do not
use the belts for two or more chil-
dren.
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seatback.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the child restraint belt sys-
tem.
Keep the belts clean and dry. If
they need cleaning, use a mild soap
solution or lukewarm water. Never
use bleach, dye, or abrasive clean-
ers. They may severely weaken the
belts.
Replace the builtin child restraint
assembly if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.
Do not use a separate child re-
straint system over the opened
builtin child restraint.
Do not use the adult lap and shoul-
der belt with the child restraint.

4. Compress the shoulder belt clip toseparate the right and left shoulder
belts.5. Pull down the seatback part of theremovable pad. Make sure the child’s
shoulders are at or below the maxi-
mum shoulder height indicator label.
The removable pad is attached by Velcros.
CAUTION
If your child’s shoulders are above
the maximum shoulder height indica-
tor label, do not use the builtin child
restraint. Your child should use the
adult lap and shoulder belts.
6. Press the removable pad against the Velcros and install the pad to the
seatback. Make sure the belts go
through the slots in the pad.
CAUTION
If you have removed the removable
pad for cleaning etc., do not use the
builtin child restraint without the
pad.

When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the antilock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the antilock brake sys-
tem activation, the brake pedal may
move a little forward.
CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tires grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at the moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The antilock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

1. Check the area around the vehicle be-fore entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head restraint
height and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Put the selector lever in “P”. If you need to restart the engine while the
vehicle is moving, put the selector le-
ver in “N”. A starter safety device will
prevent the starter from operating if the
selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving off. Before starting the engine, be sure to fol-
low the instructions in “(a) Before crank-
ing”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
airfuel mixture for starting. You can start
a cold or hot engine as follows:
1. With your foot off the accelerator ped- al, crank the engine by turning the key
to “START”. Release it when the en-
gine starts.
2. After the engine runs for about 10 se- conds, you are ready to drive.
If the weather is below freezing, let the
engine warm up for a few minutes before
driving.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” in Sec-
tion 4.

Avoid sharp turns or lockedwheel
braking, as use of chains may ad-
versely affect vehicle handling.
When driving with chains installed,
be sure to drive carefully. Slow
down before entering the curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.
NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or cause loss
of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tires, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis. Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
Initial adjustment of the tire pressure
warning system is necessary after you
have replaced your wheels. See “Tire
pressure warning system” in Section
16.
