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
263.)
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 bBuckle
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. When a passenger ’s shoulder belt is com-
pletely extended and is then retracted
even slightly, the belt is locked in that
position and cannot be extended. This fea-
ture is used to hold the child restraint
system securely. (For details, see “Child
restraint” on page 78.) To free the belt
again, fully retract the belt and then pull
the belt out once more.
If the seat belt cannot be pulled out of the
retractor, firmly pull the belt and release
it. You will then be able to smoothly pull
the belt out of the retractor.CAUTION
After inserting the tab, make sure
the tab and buckle are locked and
that the belt is not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
If the seat belt does not function
normally, immediately contact your
Toyota dealer. Do not use the seat
until the seat belt is fixed, because
it cannot protect an adult occupant
or your child from injury.

The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, brake assist system, hybrid system
control, etc. This system automatically
controls the brakes and hybrid system
to help prevent the vehicle from skid-
ding when cornering on a slippery road
surface or operating steering wheel
abruptly.
This system activates when the vehicle
speed is more than about 15 km/h (9
mph).CAUTION
Do not rely exclusively 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 unexpected ac-
cident. If the slip indicator light
flashes, sounding 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 tires other than
specified, or mixed types or size,
the vehicle stability control system
may not function correctly. When
replacing the tires or wheels, con-
tact your Toyota dealer. (See
“Checking and replacing tires” on
page 291.)

Slip indicator light
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 blinks in the follow-
ing conditions also.
The vehicle tires are racing. Utmost
care is required when driving.
When the anti−lock brake system is
operating. See “Brake system” on page
209 for details.

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.

coated parallel cords. Cords mean
the strands forming the plies in the
tire.
5. Summer tire or all season tire— An all season tire has “M+S”
on the sidewall. A tire not marked
with “M+S” is a summer tire. For
details, see “Types of tires” on
page 227.

A
radial tire has “RADIAL” on the
sidewall. The tire not marked with
“RADIAL” is a bias −ply tir e.
7. “TUBELESS” or “TUBE TYPE” —A tubeless tire does not have a
tube inside the tire and air is direct-
ly filled in the tire. A tube type tire
has a tube inside the tire and the
tube maintains the air pressure.
8. Load limit at maximum cold tire inflation pressure— For details,
see “Checking and replacing tires”

sure to which a tire may be in-
flated. For recommended cold tire
inflation pressure, see “Tires” on

ty grading” that follows.

224 Vehicle load limits include total load
capacity, seating capacity, towing ca-
pacity and cargo capacity. Follow the
load limits shown below.
Total load capacity:
379 kg (835 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
Toyota does not recommend towing
a trailer with your vehicle. Your ve-
hicle 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 l uggage
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.
