SystemOutline
SRS Airbag
The SRS (Supplemental Restraint System) airbag is provided for the driver
and front passenger. The SRS airbag has been designed to lessen the shock to
the head and chest of the driver and front passenger in the event of a frontal
impact collision as a supplement to the seat belt.
A 1±sensor type airbag system is used in which the detection of decelera-
tion during a collision as well as control of the airbag system is accom-
plished by the airbag sensor assembly.
The basic construction and operation are the same as in the '96 Avalon.
However, the inflator for front passsenger and airbag sensor assembly have
been changed.
For details, see page 111.
Cruise Control System
Once it has been set at a desired vehicle speed, this system automatically
adjusts the engine throttle position to maintain the vehicle speed at the de-
sired speed without operating the acceleration pedal.
The basic construction and operation are the same as in the previous model.
However, in the new model, a new type acutator has been adopted. Also, the
functions of the cruise control ECU has been changed. For details, see page
116.
Moon Roof
The moon roof is a tilt±up and sliding type the same as in the previous mod-
el. This system includes ªkey±off operationº, which is the same as with the
power window system. The new model offers an additional ªone±touch slide
openº function which enables the moon roof to fully open when the slide
switch is pressed toward the opening side for a few seconds.
Electrical Remote Control Mirror
The electrical remote control mirrors used in the previous model are also
used in the new model. Also, the internal heater to remove water drops from
the mirror surface is provided.
Key Reminder System
When the driver's door is opened with the ignition key in the ACC or LOCK
position, this system sounds a buzzer to warn the driver that the ignition key
has not been removed.
The basic construction and operation are the same as in the previous model.

HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Locations of SRS Components
Servicing vehicle with a Supplemental Restraint System (referred to as the SRS in the remainder of this
manual) installed.
When handling SRS components (removal, installation or inspection, etc.), always follow the directions
given in the repair manual for the relevant model year to prevent the occurrence of accidents and airbag
malfunction.
Also take the following precautions when repairing the body:
Work must be started after 90 seconds or longer from the time the ignition switch is set to the LOCK
position and the negative (±) terminal cable is disconnected from the battery.
(The airbag system is equipped with a back±up power source so that if work is started within 90 sec-
onds of disconnecting the negative (±) terminal cable of the battery, the airbag may be deployed.)
When the negative (±) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat, outside rear view mirror and power shoul-
der belt anchorage, which are all equipped with memory function, it is not possible to make a record of
the memory contents. So when the operation is finished, it will be necessary to explain this fact to the
customer, and request the customer to adjust the features and reset the memory.
When using electric welding, first disconnect the SRS connector (yellow color and 2 pins) under the
steering column near the combination switch connector on the glove compartment finish plate and
lower the front scuff plate before starting work.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.
