The SRS side and curtain shield airbags
may deploy if a serious impact occurs
to the underside of your vehicle. Some
examples are shown in the illustration.The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration. 1. SRS warning light
2. Front passenger occupant classification indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. Front passenger occupant classification system (ECU and sensors)
5. Side airbag modules (airbag and inflator)
6. Curtain shield airbag sensors
7. Side and curtain shield airbag sensors 8. Front passenger ’s seat belt buckle
switch
9. Airbag sensor assembly
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time a
chemical reaction in the inflators quickly
fills the airbags with non −toxic gas to help
restrain the lateral motion of the occu-
pants.
In a vehicle rollover, the airbag sensor
assembly triggers the curtain shield airbag
inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags
with non −toxic gas to help restrain the
lateral motion of the occupants.

NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
SRS side airbag and curtain shield
airbag system in some cases.
Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Modification of the side structure of
the passenger compartment
 Repairs made on or near the con-
sole or front seat
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS side airbags and curtain
shield airbags are operating properly. This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system and indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, “RSCA OFF” indicator light, intercon-
necting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 162 in Sec-
tion 1
−6.)
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds.
The light comes on or starts flashing
while driving.
The SRS warning light will come on and
front passenger occupant classification in-
dicator light will indicate “OFF” if there is
a malfunction in the front passenger occu-
pant classification system.

The front passenger occupant classifi-
cation indicator light indicates the ac-
tuation of the front passenger airbag,
side airbag on the front passenger seat
and front passenger ’s seat belt preten-
sioner.
The indicator light will indicate “OFF”
when the ignition switch is in the “ON”
position with the condition 2 in the table
shown below.
If the front passenger occupant classifica-
tion system determines that a person of
adult size sits in the front passenger seat
but the “OFF” indicator is illuminated, one
of the following is likely to have occurred:
A rear passenger lifts the front passen-
ger seat cushion with their legs.
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the rear seat.
To ensure the system correctly detects an
adult sitting in the front passenger seat,
make sure the above do not occur.
Make sure that the “ON” indicator is illu-
minated when an adult is seated in the
front passenger seat. If the “OFF” indica-
tor is illuminated, ask the passenger to sit
up straight, well back in the seat, and
with the seat belt worn correctly. If the
“OFF” indicator still remains illuminated,
either ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward.
The front passenger occupant classifi-
cation indicator light will indicate “ON”
and “OFF” when the ignition key is
turned to the “ON” position. After
about four seconds, it will go off. After
that, the front passenger occupant clas-
sification system operates and judges
whether to indicate “ON” or “OFF”.
The SRS warning light will come on
and front passenger occupant classifi-
cation indicator light will indicate
“OFF” if there is a malfunction in the
front passenger occupant classification
system.

∗1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may
recognize him/her as a child depending on his/her physique and posture.
∗2: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/h er
as an adult depending on his/her physique or posture.
∗ 3: Never install a rear −facing child restraint system on the front passenger seat. A forward −facing child restraint system should only be
installed on the front passenger seat when it is unavoidable. (See “Child restraint” on page 107 in this Section as for install ing the
child restraint system.)
∗ 4: In the event the front passenger does not wear a seat belt.

When it is unavoidable to install the
forwardfacing child restraint sys-
tem on the front passenger seat,
install the child restraint system on
the front passenger seat in the
proper order. (As for the installation
order, see “—Installation with seat
belt” on page 110 in this Section.)
Do not remove the seat.
Do not kick the front passenger
seat or subject it to severe impact.
Otherwise, the SRS warning light
may come on to indicate a malfunc-
tion of the detection system. In this
case, contact your Toyota dealer im-
mediately.
The front passenger occupant classifica-
tion indicator light may indicate “ON” (the
front passenger airbag and side airbag on
the front passenger seat may deploy)
even if observing the above cautions,
when a child sits in, or a forward−facing
child restraint system is installed on the
front passenger seat. Refer to all the cau-
tions in “SRS driver airbag and front pas-
senger airbag” on page 86 and “Child re-
straint” on page 107 in this Section.
The roll sensing of curtain shield air-
bags off switch (“RSCA OFF” switch)
can turn off the curtain shield airbags
and seat belt pretensioners in a vehicle
rollover. This switch should only be
used if inflation is not desired (such as
extreme offroad driving). When you push the “RSCA OFF” switch
for a few seconds with the ignition switch
on, the “RSCA OFF” indicator light comes
on and the roll sensing function is turned
off. When you push the switch again, the
indicator light goes off and the roll sens-
ing function is turned on. (For details
about the roll sensing function, see “SRS
side airbags and curtain shield airbags” on
page 93 in this Section.)
In a severe side impact, the curtain shield
airbags on impacted side will inflate even
if the roll sensing function is turned off.
(For details about the curtain shield air-
bags, see “SRS side airbags and curtain
shield airbags” on page 93 in this Sec-
tion.)
In a severe frontal impact, the seat belt
pretensioners will work even if the roll
sensing function is turned off. (For details
about the seat belt pretensioners, see
“—Seat belt pretensioners” on page 83 in
this Section.)
If the ignition switch is turned to “ACC” or
“LOCK” with the roll sensing function off
and then the ignition switch is turned back
to “ON”, the roll sensing function will turn
back on automatically.

The gauge indicates the approximate
quantity of fuel remaining in the tank
when the ignition switch is on.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
It is a good idea to keep the tank over
1/4 full.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
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.The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.

when the ignition key is turned to the
“ON” position even after the parking brake
is released.
When the brake fluid level is low...
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
Have your vehicle checked at your
Toyota dealer in the following cases:
The light does not come on even if the
parking brake is applied when the igni-
tion key is in the “ON” position.
The light does not come on even if the
ignition key is turned on with the park-
ing brake released.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Toyota dealer.
The light does not turn off even
after the parking brake is released
while the engine is running.
In this case, the brakes may not
work properly and your stopping
distance will become longer. De-
press the brake pedal firmly and
bring the vehicle to an immediate
stop.
The brake system warning light re-
mains on together with the “ABS”
warning light.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely un-
stable during braking.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
buzzer come on if the driver’s seat belt
is not fastened. Unless the driver fastens
the belt, the light continues flashing and
the buzzer sounds for about 4 to 8 se-
conds.
(c) Front Passenger ’s Seat Belt Re- minder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt.
If luggage or other load is placed on the
front passenger seat, depending on its
weight, the reminder light may flash.
