Passenger Air Bag Assembly
Service Precautions
WARNING: S A F E T Y P R ECAUTIONS MUST BE
FOLLOWED WHEN HANDLING A DEPLOYED AIR
BAG ASSEMBLY. AFTER DEPLOYMENT, THE AIR
BAG ASSEMBLY SURFACE MAY CONTAIN A SMALL
AMOUNT OF SODIUM HYDROXIDE, A BY±PRODUCT
OF THE DEPLOYMENT REACTION, THAT IS
IRRITATING TO THE SKIN AND EYES. MOST OF THE
POWER ON THE AIR BAG ASSEMBLY IS
HARMLESS. AS A PRECAUTION, WEAR GLOVES
AND SAFETY GLASSES WHEN HANDLING A
DEPLOYED AIR BAG ASSEMBLY, AND WASH YOUR
HANDS WITH MILD SOAP AND WATER
AFTERWARDS.
WARNING: W H E N C A R RY I N G A L I V E A I R B A G
ASSEMBLY, MAKE SURE THE BAG AND TRIM
COVER ARE POINTED AWAY FROM YOU. NEVER
CARRY AIR BAG ASSEMBLY BY THE WIRES OR
CONNECTOR ON THE UNDERSIDE OF MODULE. IN
THE CASE OF AN ACCIDENTAL DEPLOYMENT, THE
BAG WILL THEN DEPLOY WITH MINIMAL CHANCE
OF INJURY. WHEN PLACING ALIVE AIR BAG
ASSEMBLY ON A BENCH OR OTHER SURFACE,
ALWAYS FACE BAG AND RIM COVER UP, AWAY
FROM THE SURFACE. NEVER REST A STEERING
COLUMN ASSEMBLY ON THE STEERING WHEEL
WITH THE AIR BAG ASSEMBLY FACE DOWN AND
COLUMN VERTICAL. THIS IS NECESSARY SO THAT
A FREE SPACE IS PROVIDED TO ALLOW THE AIR
BAG ASSEMBLY TO EXPAND IN THE UNLIKELY
EVENT OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY COULD RESULT.
NOTE: IN THE EVENT DEPLOYMENT HAS
OCCURRED, INSPECT COIL ASSEMBLY WIRE FOR
ANY SIGNS OF SCORCHING, MELTING OR ANY
OTHER DAMAGE DUE TO EXCESSIVE HEAT. IF THE
COIL HAS BEEN DAMAGED, REPLACE IT.
