Other supplemental front-impact air bag
precautions
WARNING
• Do not place any objects on the steering
wheel pad or on the instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
• No unauthorized changes should be
made to any components or wiring of the
supplemental air bag system. This is to
prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
• Do not make unauthorized changes to
your vehicle's electrical system, suspen-
sion system or front end structure. This
could affect proper operation of the
front air bag system. •
Tampering with the front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument panel
assembly by placing material over the
steering wheel pad and above the instru-
ment panel or by installing additional
trim material around the air bag system.
• Removing or modifying the front pas-
senger seat may affect the function of
the air bag system and result in serious
personal injury.
• Modifying or tampering with the front
passenger seat may result in serious per-
sonal injury. For example, do not change
the front seats by placing material on the
seat cushion or by installing additional
trim material, such as seat covers, on the
seat that are not specifically designed to
assure proper air bag operation. Addi-
tionally, do not stow any objects under
the front passenger seat or the seat
cushion and seatback. Such objects may
interfere with the proper operation of
the occupant classification sensor
(weight sensor).

WARNING
• Once a front air bag, side air bag, curtain
air bag or knee air bag has inflated, the
air bag module will not function again
and must be replaced. Additionally, the
activated pretensioner(s) must also be
replaced. The air bag module and preten-
sioner(s) should be replaced. It is recom-
mended that you visit an INFINITI re-
tailer for this service. However, the air
bag module and pretensioner(s) cannot
be repaired.
• The front air bag, side air bag, curtain air
bag, knee air bag systems and the pre-
tensioner system should be inspected if
there is any damage to the front end or
side portion of the vehicle. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
• If you need to dispose of a supplemental
air bag or pretensioner systems or scrap
the vehicle, it is recommended that you
visit an INFINITI retailer. Incorrect dis-
posal procedures could cause personal
injury. •
If there is an impact to your vehicle from
any direction, your Occupant Classifica-
tion Sensor (OCS) should be checked to
verify it is still functioning correctly. It is
recommended that you visit an INFINITI
retailer for this service. The OCS should
be checked even if no air bags deploy as a
result of the impact. Failure to verify
proper OCS function may result in an im-
proper air bag deployment resulting in
injury or death.
