KEY CODING
KEY USAGE AND IDENTIFICATION
Key is used for ignition and door lock cylinder. Keys are cut on both
edges to make them reversible.
Key identification is obtained from five character key code stamped
on key code tag. Using this key code, key code cutting combination
can be determined from a code list (available to owners of key cut-
ting equipment from suppliers).
If key codes are not available from records or tags, key code can
be obtained from the right hand door lock cylinder (if lock has not
been replaced). Lock cylinders supplied by the factory as service
parts are unmarked.
If original key is available, key code cutting combination can be de-
termined by laying key.

GENERAL DESCRIPTION
Seat belt with ELR
The seat belt with Emergency Locking Retractor (ELR) is designed so that it locks immediately (to prevent the web-
bing from being pulled out of the retractor any further) when any of the following items is detected as exceeding
each set value; speed at which the webbing is pulled out of the retractor, acceleration or deceleration of the vehicle
speed, and inclination.
Seat belt with A-ELR
The automatic and emergency locking retractor (A-ELR) works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an Automatic Locking Retractor (ALR) till it is retracted fully.
ALR: Automatically locks when the webbing is pulled out from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further, unless it is wound all the way back into the retractor, which
releases the lock and allows the webbing to be pulled out.
Driver and front passenger side air bags
The driver and front passenger side air bags are components of the air bag system. In occurrence of a front collision
with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supplement
protection offered by the driver and front passenger seat belts.

the driver air bag (inflator) module is deployed from the center of the steering column

the passenger air bag (inflator) module from the top of the instrument panel in front of the front passenger seat

the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may
be used. Fasteners that are not reused, and those requiring thread-locking compound, will be called
out. The correct torque value must be used when installing fasteners that require it. If the above proce-
dures are not followed, parts or system damage could result.

GENERAL DESCRIPTION
With the air bag system which includes air bags for both the driver's
and passenger's sides as well as the seat belt pretensioners (if
equipped), the sag of the seat belt is taken up, the driver air bag (in-
flator) module is deployed from the center of the steering column
and the passenger air bag (inflator) module from the top of the
instrument panel in front of the front passenger seat in occurrence
of a front collision with an impact larger than a certain set value to
supplement protection offered by the driver and front passenger
seat belts.
The air bag system is designed to activate only in severe frontal col-
lisions. It is not designed to activate in rear impacts, side impacts,
rollovers, or minor frontal collisions, since it would offer no protec-
tion in those types of accidents.
