CAUTION
Persons should ride in their seats
properly wearing their seat belts
whenever the vehicle is moving.
Otherwise, they are much more likely
to suffer serious bodily injury or
death in the event of sudden braking
or a collision.
When using the seat belts, observe
the following:
Use the belt for only one person at
a time. Do not use a single belt for
two or more people—even children.
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 maximum 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.
Be careful not to damage the belt
webbing or hardware. Take care that
they do not get caught or pinched
in the seat or doors.
Inspect the belt system periodically.
Check for cuts, fraying, and loose
parts. Damaged parts should be re-
placed. Do not disassemble or
modify the system.
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, or allow them to come into
contact with the belt—they may se-
verely weaken the belts. (See
“Cleaning the interior” on page
173.)
Replace the belt assembly (includ-
ing bolts) if it has been used in a
severe impact. The entire assembly
should be replaced even if damage
is not obvious.

Ta b
Buckle
Adjust the seat as needed and sit up
straight and well back in the seat. To
fasten your belt, pull it out of the re-
tractor and insert the tab into the
buckle.
You will hear a click when the tab locks
into the buckle.
The seat belt length automatically adjusts
to your size and the seat position.
The retractor will lock the belt during a
sudden stop or on impact. It also may
lock if you lean forward too quickly. A
slow, easy motion will allow the belt to
extend, and you can move around freely.

The vehicle stability control system
helps provide integrated control of the
systems such as an antilock brake
system, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
This system activates when the vehicle
speed is about more than 15 km/h (9
mph).
You may hear a sound in the engine
compartment for a few seconds just after
the vehicle begins to move. This means
that the system is in the self−check mode,
but does not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an accident. If the
slip indicator light flashes, sound-
ing an alarm, special care should
be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Scion dealer. (See
“Checking and replacing tires” on
page 198.)
In situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tires or tire chains.
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Scion dealer.

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 tire 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 a 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.

“ABS” warning light
This light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system works prop-
erly, the light turns off after a few sec-
onds. Thereafter, if the system malfunc-
tions, the light comes on again.
When the “ABS” warning light is on (and the
brake system warning light is off), the anti
lock brake system, the brake assist system,
the traction control system and the vehicle
stability control system do not operate, but
the brake system still operates conventional-
ly.

133 Vehicle load limits include total load
capacity, seating capacity, towing ca-
pacity and cargo capacity. Follow the
load limits shown below.
Total load capacity:
375 kg (825 lb.)
Total load capacity means combined
weight of occupants, cargo and lug-
gage. Tongue load is included when
trailer towing.
Seating capacity:
Total 5 (Front 2, Rear 3)
Seating capacity means the maximum
number of occupants whose esti-
mated average weight is 68 kg (150
lb.) per person. Depending on the
weight of each person, the seating ca-
pacity given may exceed the total
load capacity.
NOTICE
Even if the number of occupants
are within the seating capacity,
do not exceed the total load ca-
pacity.
Towing capacity
Scion does not recommend towing a
trailer with your vehicle. Your vehicle
is not designed for trailer towing.
Cargo capacity
Cargo capacity may increase or de-
crease depending on the size (weight)
and the number of occupants. For de-
tails, see “Capacity and distribution”
that follows.
CAUTION
Do not apply the load more than
each load limit. That may cause
not only damage to the tires, but
also deterioration to the steering
ability and braking ability, which
may cause an accident.
When stowing cargo and luggage in
the vehicle, observe the following:
Put cargo and luggage in the lug-
gage compartment when at all
possible. Be sure all items are se-
cured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
balance.
For better fuel economy, do not
carry unneeded weight.
CAUTION
To prevent cargo and luggage
from sliding forward during
braking, do not stack anything
in the luggage compartment.
Keep cargo and luggage low,
as close to the floor as pos-
sible.

136
CAUTION
Even if the total load of occu-
pant’s weight and the cargo load
is less than the total load capac-
ity, do not apply the load uneven-
ly. That may cause not only dam-
age to the tire but also deteriora-
tion to the steering ability due to
unbalance of the vehicle, causing
an accident.
Types of tires
Determine what kind of tires your
vehicle is originally equipped with.
1. Summer tires
Summer tires are high−speed capabil-
ity tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow−covered or icy roads.
For driving on snow−covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires.
2. All season tires
All season tires are designed to pro-
vide better traction in snow and to be
adequate for driving in most winter
conditions, as well as for use all year
round.All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described on page 125.
CAUTION
Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.
Do not use tires other than the
manufacturer’s designated
tires, and do not mix tires or
wheels of the sizes different
from the originally equipped
tires and wheels.

To remove the jack, move the driver
seat to the front−most position and re-
move the cover.
To rem ov e: Tur n the joint in direction
1 by hand until the jack is free.
To store: Turn the joint in direction 2
by hand until the jack is firmly secured
to prevent it flying forward during a
collision or sudden braking.To remove the spare tire, loosen the
bolt and remove it.
Then take the spare tire out of the
vehicle.
When storing the spare tire, put it in
place with the outer side of the wheel
facing up. Then secure the tire by re-
peating the above removal steps in
reverse order to prevent it from flying
forward during a collision or sudden
braking.
The compact tire storage area is de-
signed only for a compact spare tire.
Standard size tire cannot be stored
in this storage area.
—Blocking the wheel
2. Block the wheel diagonally op-
posite the flat tire to keep the
vehicle from rolling when it is
jacked up.
When blocking the wheel, place a
wheel block in front of one of the front
wheels or behind one of the rear
wheels.
