CAUTION
GI
3. When placing a live air bag module on any surface, always face the trim cover upward. This will reduce
the motion of the module if it is accidentally deployed.
4. When handling a deployed air bag module, wear gloves and safety glasses because the deployed air
bag module may display deposits of sodium hydroxide, a product of the gas generant combustion.
5. An air bag module must disposed of only by the proper procedure recommended for the specific situa-
tion. (Refer to page T -160.)
Crash Sensor Installation
1. The angle and direction of the sensor is very important for its proper operation. If a vehicle has been in-
volved in a crash where the its front sheet metal has been damaged, inspect the body structure at the
sensor mounting area for deformation. If damaged, restore it to its original shape.
2. When installing a crash sensor, be sure to tighten the mounting bolts to the specified torque to ensure
proper grounding. The ground circuit is made directly through the sensor's mounting plate.
Adjustment of Clock Spring Connector
When the steering wheel is removed or the clock spring connector is replaced, the clockspring connector
must be properly aligned.
Align the clock spring connector as follows:
(1) Set the front wheels straight ahead.
(2) Turn the clock spring connector clockwise until it stops. Do not force it.
(3) Return it 2.5 turns.
(4) Align (counterclockwise) the mark on the clock spring connector to the outer housing.
(5) Carefully install the steering wheel without disturbing the clockspring connector.

Mazda genuine battery replacement kit or equivalent.
(Refer to page G-10 for replacement.)
POWER CONNECTOR IN ENGINE COMPARTMENT
1. When using externally powered test equippment, connect
it to the special power connector (Blue: i-pin) for battery
voltage.
2. Do not ground the power connector terminal; the Wiper 20A
fuse will be burned.
AUDIO ANTI-THEFT SYSTEM
An audio with an anti-theft function is optionally available.
Before removing the negative battery terminal or disconnect-
ing the audio power source, obtain the code number and deac-
tivate the audio anti-theft system. (Refer to page T -113.)
