SRS airbag system diagnostic data
If your vehicle is equipped with a vehicle stability control
(VSC) system, its Electronic Control Unit (ECU) may con-
tain another EDR. There are a variety of driving situations
which include activating the VSC under which the VSC
EDR will record certain information. The VSC EDR may
record some or all of the following information:
 Behavior of the vehicle
 Steering wheel angle
 Vehicle speed
 To what extent the accelerator pedal was depressed
 To what extent the brake pedal was applied
 To what extent the ECU controlled the condition of
the 4 wheels
 Vehicle stability control system di agnostic data
The information above is intended to be used for the
purpose of improving vehicle safety performance. Unlike
general data recorders, the EDR does not record sound
data such as conversation between passengers.Toyota will not disclose the data recorded in an EDR to a
third party except when:
 An agreement from the vehicle’s owner (or the leas-
ing company for a leased vehicle) is obtained
 Officially requested by the police or other authorities
 Used as a defense for Toyota in a law suit
 Ordered by the court
However, if necessary Toyota will:
 Use the data for research on Toyota vehicle safety
performance
 Disclose the data to a third party for research pur-
poses without disclosing details of the vehicle owner,
and only when it is deemed necessary
 Disclose summarized data cleared of vehicle identifi-
cation information to a non −Toyota organization for
research purposes

1. Lock switch
2. Unlock switch
3. Alarm switch
4. Sliding door open switch (right side)
5. Back door open switch
6. Sliding door open switch (left side)The wireless remote control system is
designed to lock or unlock all the side
doors and back door, or activate the
panic mode from a distance within
approximately 1 m (3 ft.) of the vehicle.
On some models, the system also al-
lows you to activate the theft deterrent
system from the same distance.
When you operate any switch, push it
slowly and securely.
The wireless remote control transmitter is
an electronic component. Observe the fol-
lowing instructions in order not to cause
damage to the wireless remote control
transmitter.
Do not leave the transmitter in places
where the temperature becomes high
such as on the dashboard.
Do not disassemble it.
Avoid knocking it hard against other
objects or dropping it.
Avoid putting it in water.
You can use up to 4 wireless remote con-
trol transmitters for the same vehicle.
Contact your Toyota dealer for detailed
information. If the wireless remote control transmitter
does not actuate the doors or alarm, or
operate from a normal distance:
Check for closeness to a radio trans-
mitter such as a radio station or an
airport which can interfere with normal
operation of the transmitter.
The battery may have been consumed.
Check the battery in the transmitter. To
replace the battery, see “—Replacing
battery” on page 20.
If you lose your wireless remote control
transmitter, contact your Toyota dealer as
soon as possible to avoid the possibility
of theft, or an accident. (See “If you lose
your wireless remote control transmitter”
on page 493 in Section 4.)

When the engine switch is turned to
the “ON” position, the light does not
come on, remains on for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving.
If any seat belt does not retract or
cannot be pulled out due to a malfunc-
tion or activation of the relevant seat
belt pretensioner.

surrounding area has been damaged.
In the following cases, contact your Toyota
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the seat belt pretensioners to operate.

or surrounding area is scratched,
cracked, or otherwise damaged.
The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
Your vehicle is equipped with “ADVANCED
AIRBAGS” designed based on US motor
vehicle safety standards (FMVSS208). The
airbag system controls airbag deployment
power for the driver and front passenger.
The driver airbag system consists of the
driver seat’s position sensor etc. The front
passenger ’s airbag system consists of the
front passenger occupant classification
sensor etc.

NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
Your vehicle is equipped with a front
passenger occupant classification sys-
tem. This system detects the conditions
1—4 in the table on page 137 and based
on these conditions activates or deacti-
vates the following systems;
Front passenger airbag
Side airbag on the front passenger
seat
Front passenger ’s seat belt pretension-
er
The system monitors the weight and
load on the front passenger seat, and
the seat belt buckle switch to determine
conditions 1—4.
In order for the system to detect the
conditions correctly, do not do any of
the following:
Apply a heavy load to the front pas-
senger seat or equipment (e.g. seat-
back table, grocery bag hooks, armrest
or auxiliary box).
Attach a commercial seatback table,
etc. to the front passenger seat seat-
back.
Put weight on the front passenger seat
by putting your hands or feet on the
seatback from the rear passenger seat.
The “AIR BAG ON” and “AIR BAG OFF”
indicator lights indicate the actuation of
the front passenger airbag, side airbag
on the front passenger seat and front
passenger ’s seat belt pretensioner.
The “AIR BAG OFF” indicator light will be
illuminated when the engine switch is in
the “ON” position with the condition 2 in
the table shown below.

∗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 139 in this Section as for install ing the
child restraint system.)
