2000 TOYOTA CAMRY belt

CIRCUIT DESCRIPTION
The main oxygen sensor is located in the exhaust manifold.
It indirectly determines whether the fuel mixture is rich or lean by detecting the concentration of
oxygen present in the exhaust gas.
Engine speed varies by more than 15 rpm over
the preceding crank position period during a period
of 50 sec. or more under conditions (a) and (b).

ENGINE
5S±FE ENGINE
 DESCRIPTION
The 5S±FE engine has improved the torque in the low±to±mid±speed range through improvements made for the intake
and exhaust systems and the combustion chamber. In addition, its exhaust emissions have been reduced through the
improvements made for the exhaust system and the engine control system.

93 BODYÐLIGHTWEIGHT AND HIGHLY RIGID BODY
Impact Absorbing Structure for Side Collision
Impact energy of a side collision directed to the cabin area is dispersed throughout the body via pillar reinforcements,
side impact protection beams, floor cross members, etc. This dispersion of energy keeps the energy directed to the
cabin to a minimum level. In additon, the body is made highly rigid through the cabin space. And, in order to make
the door more energy absorbent, a closed cross section configuration is provided at the belt line area of the front and
rear doors.
Also, a soft upper interior construction has been adopted. With this type of constrution, if the occupant's head collides
against the roof side rail in reaction to a collision, the inner panel of the roof side rail collapses to reduct the impact.

CRS (CHILD RESTRAINT SYSTEM)
The CRS is enclosed in the seatback for the right rear seat in order to provide a comfortable and safe restraint seating
for a child in the 22 to 60 lbs. (10.0 to 27.2 kg) range. When the CRS is not being used, it can be retracted to perform
the normal seating function of the rear seat.
The CRS uses a 5±point seat belt.

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.

 SRS AIRBAG
1. General
The SRS (Supplemental Restraint System) airbag is designed to help lessening the shock to the driver and front
passenger as a supplement to the seat belt. In a collision, the aribag sensor detects the shock and if the front±to±rear
shock is greater than a specified value, the airbags stored in the steering wheel pad for the driver and above the glove
box for the front passenger inflate instantly to help reducing the likelihood of the driver's or front passenger's head
and chest directly hitting the steering wheel or instrument panel.
As in the '96 Avalon, a 1±sensor type airbag system is used, in chich the detection of deceleration during a collision
is accomplished by the airbag sensor enclosed in the airbag snesor assembly.
The airbag system is controlled by the airbag sensor assembly. It has a self±diagnosis function. When it detects a
system malfunction, it lights up the SRS warning light on the combination meter to alert the driver.
The basic construction and operation are the same as in teh '96 Avalon. However, 2 types of the inflator for front
passenger have been adopted in the new Camry: TRW made and Morton made. Also, the construction of airbag sensor
assembly has been changed.

The activation processes of the SRS airbag is as illustrated below.
