CALIFORNIA PROPOSITION 65 WARNING
WARNING
Operating, servicing and maintaining a passenger vehicle or
off-highway motor vehicle can expose you to chemicals
including engine exhaust, carbon monoxide, phthalates, and
lead, which are known to the State of California to cause
cancer and birth defects or other reproductive harm. To
minimize exposure, avoid breathing exhaust, do not idle the
engine except as necessary, service your vehicle in a well-
ventilated area and wear gloves or wash your hands
frequently when servicing your vehicle. For more information
go to www.P65Warnings.ca.gov/passenger-vehicle.

For descriptions specified for all-wheel drive
models, anAWDmark is placed at the begin-
ning of the applicable sections/items.
As with other vehicles with features for off-
road use, failure to operate all-wheel drive
models correctly may result in loss of control
or an accident. For additional information,
see “Driving safety precautions” (P. 5-10).
ON-PAVEMENT AND OFF-ROAD DRIVING
This vehicle will handle and maneuver dif-
ferently from an ordinary passenger car
because it has a higher center of gravity for
off-road use. As with other vehicles with
features of this type, failure to operate this
vehicle correctly may result in loss of con-
trol or an accident.
For additional information, see “On- pave-
ment and off-road driving precautions”
(P. 5-8), “Avoiding collision and roll- over”
(P. 5-8) and “Driving safety precautions”
(P. 5-10).
MODIFICATION OF YOUR VEHICLE
This vehicle should not be modified. Modi-
fication could affect its performance,
safety, emissions or durability and may
even violate governmental regulations. In
addition, damage or performance problems
resulting from modifications may not be
covered under INFINITI warranties.
WARNING
Installing an aftermarket On-Board Diag-
nostic (OBD) plug-in device that uses the
port during normal driving, for example
remote insurance company monitoring,
remote vehicle diagnostics, telematics or
engine reprogramming, may cause inter-
ference or damage to vehicle systems. We
do not recommend or endorse the use of
any aftermarket OBD plug-in devices, un-
less specifically approved by INFINITI. The
vehicle warranty may not cover damage
caused by any aftermarket plug-in device. This manual includes information for all fea-
tures and equipment available on this model.
Features and equipment in your vehicle may
vary depending on model, trim level, options
selected, order, date of production, region or
availability. Therefore, you may find informa-
tion about features or equipment that are not
included or installed on your vehicle.
All information, specifications and illustra-
tions in this manual are those in effect at the
time of printing. INFINITI reserves the right
to change specifications, performance, de-
sign or component suppliers without notice
and without obligation. From time to time,
INFINITI may update or revise this manual to

formation currently available. Please care-
fully read and retain with this manual all revi-
sion updates sent to you by INFINITI to

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. 1-12).
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
engine hood is operational. For additional
information, see “Warning lights, indicator
lights and audible reminders” (P. 2-9).
