2. Widen the gap between the seat
cushion and seatback slightly and
confirm the position of the lower an-
chorages near the button on the
seatback.
3. Type AÐLatch the hooks of lower
straps onto the anchorages and
tighten the lower straps.
Type BÐLatch the buckles onto the
anchorages.
For owners in CanadaÐThe symbol on
a child restraint system indicates the pres-
ence of a lower connector system.
If your child restraint system has a top
strap, it should be anchored. (For the
installation of the top strap, see ÐUsing
a top strapº on page 105 in this Section.)
For installation details, refer to the instruc-
tion manual equipped with each product.CAUTION
When using the lower anchorages
for the child restraint system, be
sure that there are no irregular ob-
jects around the anchorages or that
the seat belt is not caught.
Push and pull the child restraint
system in different directions to be
sure it is secure. Follow all the
installation instructions provided by
its manufacturer.
When using the lower anchorages
for the child restraint system, en-
sure that the seat is moved to the
rear- most position, with the seat-
back close to the child restraint
system.
After securing the child restraint
system, never slide or recline the
seat.
Do not install a child restraint sys-
tem on the second seat if it inter-
feres with the lock mechanism of
the front seats. Otherwise, the child
or front seat occupant(s) may be
killed or seriously injured in case
of sudden braking or a collision.

when the ignition key is in the ONº posi-
tion.
When the parking brake is applied...
This light comes on for a few seconds
when the ignition key is turned to the
ONº position even after the parking brake
is released.
If the vehicles speed rises above 5 km/h
(3 mph) with the parking brake applied, a
buzzer sounds.
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 ONº 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 ABSº
warning light.
In this case, not only the anti- lock
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.

tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
In this case, slow down and have your
vehicle checked/repaired by your Toyota
dealer as soon as possible.

er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to ACCº or
LOCKº position.

SRS
NOTICE: When inspecting or repairing the SRS, perform service in accordance with the following precautionary instructions
and the procedure, and precautions in the Repair Manual applicable for the model year.
Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most important source of information
when troubleshooting. When troubleshooting the SRS, always inspect the DTCs before disconnecting the battery.
Work must be started more than 90 seconds after the ignition SW is turned to the ºLOCKº position and the
negative (-) terminal cable is disconnected from the battery.
(The SRS is equipped with a back-up power source so that if work is started within 90 seconds from
disconnecting the negative (-) terminal cable of the battery, the SRS may deploy.)
When the negative (-) terminal cable is disconnected from the battery, the memory of the clock and audio system will be
cleared. So before starting work, make a record of the contents in the audio memory system. When work is finished,
reset the audio systems as they were before and adjust the clock. Some vehicles have power tilt steering, power
telescopic steering, power seat and power outside rear view mirror which are all equipped with memory function.
However, it is not possible to make a record of these memory contents. So when the work is finished, it will be
necessary to explain it to your customer, and ask the customer to adjust the features and reset the memory. To avoid
erasing the memory in each system, never use a back-up power supply from outside the vehicle.
Before repair, remove the airbag sensor if shocks are likely to be applied to the sensor during repair.
Do not expose the following parts directly to hot air or flame;
Even in cases of a minor collision where the SRS does not deploy, the following parts should be inspected;
Never use SRS parts from another vehicle. When replacing parts, replace with new parts.
For the purpose of reuse, never disassemble and repair the following parts.
If the following parts have been dropped, or have cracks, dents and other defects in their case, bracket, and connector,
replace with new one.
Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting electrical circuits of the system.
Information labels are attached to the periphery of the SRS components. Follow the instructions of the notice.
After work on the SRS is completed, check the SRS warning light.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN section of the Repair
Manual.

The SRS is a driver and front passenger protection device which has a supplemental role to the seat belts.
When the ignition SW is turned to ON, the current from the IGN fuse flows to TERMINAL (B) 5 of the airbag sensor
assembly.
If an accident occurs while driving, when the frontal impact exceeds a set level, the current from the IGN fuse flows to
TERMINALS (B) 14, (B) 16, (B) 10, (B) 8, (A) 8 (w/ curtain shield airbag), or (A) 2 (w/o curtain shield airbag) and (C) 9 (w/
curtain shield airbag), or (C) 5 (w/o curtain shield airbag) of the airbag sensor assembly to the airbag squibs and the
pretensioners to TERMINALS (B) 13, (B) 17, (B) 11, (B) 7, (A) 7 (w/ curtain shield airbag), or (A) 1 (w/o curtain shield airbag)
and (C) 10 (w/ curtain shield airbag), or (C) 6 (w/o curtain shield airbag) of the airbag sensor assembly to TERMINAL (B) 27,
(B) 28 or BODY GROUND to GROUND, so that current flows to the airbag squibs and the pretensioners and causes them to
operate.
When the side impact also exceeds a set level, the current from the IGN fuse flows to TERMINALS (A) 12, (C) 5, (A) 9 and
(C) 8 of the airbag sensor assembly to the side airbag squibs and the curtain shield airbag squibs TERMINALS (A) 11, (C) 6,
(A) 10 and (C) 7 of the airbag sensor assembly to TERMINAL (B) 27, (B) 28 or BODY GROUND to GROUND, causing side
airbag squibs and curtain shield airbag squibs to operate.
The airbag stored inside the steering wheel pad is instantaneously expanded to soften the shock to the driver.
The airbag stored inside the passenger's instrument panel is instantaneously expanded to soften the shock to the front
passenger.
Side airbags are instantaneously expanded to soften the shock of side to the driver and front passenger.
The curtain shield airbag can ease an impact on the head of the front and rear passengers and reduce risks of injury.
In a head-on crash, the driver moves forward and may strike his/her lower limbs against the instrument panel, the key
cylinder, etc.
The pretensioners make sure of the seat belt restrainability.
