WARNING: SAFETY PRECAUTIONS 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

FROM THE SURFACE. NEVER REST A STEERING
COLUMN ASSEMBLY ON THE STEERING WHEEL
WITH THE AIR BAG ASSEMBLY FACE DOWN AND

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.
