FRONT POWER SEAT
ADJUSTMENT
Operating tips
• The power seat motor has an auto-resetoverload protection circuit. If the motor
stops during operation, wait 30 seconds
then reactivate the switch.
• Do not operate the power seat switch for a long period of time when the engine is off.
This will discharge the battery.
For additional information, see “Memory
seat” (P. 3-37).
Forward and backward
Moving the switch as shown will slide the
seat forward or backward to the desired
position.
Reclining
Move the recline switch as shown until the
desired angle is obtained.
The reclining feature allows adjustment of
the seatback for occupants of different sizes
for added comfort and to help obtain proper
seat belt fit. For additional information, see
“Precautions on seat belt usage” (P. 1-11).
Also, the seatback can be reclined to allow
occupants to rest when the vehicle is parked.

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).
POP-UP ENGINE HOOD
Safety-Seats, seat belts and supplemental restraint system1-63

WARNING
• The pop-up engine hood will not activate
in the event of a side impact, rear impact
or rollover collision.
• The pop-up engine hood may not acti-
vate in the event of a corner impact col-
lision of the front bumper.
• No unauthorized changes should be
made to any components including hood
and front bumper, or wiring of the
pop-up engine hood system. This is to
prevent accidental or improper activa-
tion, or damage to the pop-up engine
hood system.
• It is recommended that work performed
around or on the pop-up engine hood
system should be done by an INFINITI
retailer. The wiring of the pop-up engine
hood system should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the pop-up engine
hood system. This could affect proper
operation of the pop-up engine hood and
cause accidental and improper
activation. •
Do not pull the hood lock release handle
or push the hood down after the pop-up
engine hood system activates. Doing so
could cause personal injury or damage to
the hood because the hood cannot be
closed manually after the system is acti-
vated. When the pop-up engine hood ac-
tivates, it is recommended that you visit
an INFINITI retailer.
• If you need to dispose of the pop-up en-
gine hood system, or scrap the vehicle, it
is recommended that you visit an
INFINITI retailer. Correct pop-up engine
hood system disposal procedures are set
forth in the appropriate INFINITI Service
Manual. Incorrect disposal procedures
could cause personal injury.
• The pop-up engine hood cannot be re-
used after activation. It is recommended
that you visit an INFINITI retailer for re-
placement. If the vehicle becomes in-
volved in a frontal collision but the
pop-up engine hood system is not acti-
vated, it is recommended that you have
the pop-up engine hood system checked
and, if necessary, replaced by an
INFINITI retailer. •
Immediately after the pop-up engine
hood has been activated, do not touch
the components because the lifters will
be hot. You may severely burn yourself.
POP-UP ENGINE HOOD
ACTIVATION CONDITIONS
When the pop-up engine hood will activate
The pop-up engine hood 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).
The pop-up engine hood activates when the
collision impact reaches a certain level even if
the collision does not cause damage to the
front bumper. In addition, it may activate
when the vehicle collides with small animals,
lumps of snow or any other objects, depend-
ing on the condition and speed of collision.
When the vehicle receives an impact to the
undercarriage or a lower part of the front
bumper, the pop-up engine hood may also
activate. Reduce speed and be careful when
driving on a road surface that seems likely to
impact the undercarriage or a lower part of
the front bumper. Some examples are shown
in the following illustrations.
