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. In certain frontal collisions with a pedestrian,
the pop-up engine hood system can help re-
duce impact to the head of a pedestrian. This
system is designed to pop up the rear end of
the hood in certain frontal collisions to pro-
vide specified clearance between the hood
and the engine compartment to reduce im-
pact to a pedestrian.
The pop-up engine hood system activates in
certain frontal collisions with pedestrians or
objects when the vehicle is driven at speeds
between approximately 12 and 37 mph (20
and 60 km/h). While driving, the pop-up en-
gine hood may activate in the event of an
impact collision involving the bottom of the
vehicle or bumper. The system activates
when the collision impact reaches a certain
level even though the collision does not cause
damage to the bumper.
The pop-up engine hood operates only when
the ignition switch is in the ON position.
When the ignition switch is in the ON posi-
tion, the pop-up engine hood warning light
illuminates for about 7 seconds and then
turns off. This indicates that the pop-up en-
gine hood is operational. For additional in-
formation, see “Warning lights, indicator
lights and audible reminders” (P. 2-9).
