TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low – Add Air” warning
appears in the vehicle information dis-
play, one or more of your tires is sig-
nificantly under-inflated. If equipped,
the system also displays pressure of all
tires (except the spare tire) on the dis- play screen by sending a signal from a
sensor that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above
16 mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
For additional information, refer to
“Low tire pressure warning light” in the
“Instruments and controls” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving”
section and “Flat tire” in the “In case of
emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on
the F.M.V.S.S./C.M.V.S.S. certifica-
tion label or the Tire and Loading In-
formation label under the “Cold Tire
Pressure” heading. The Tire and Load-
ing Information label is affixed to thedriver side center pillar. Tire pressures
should be checked regularly because:
∙ Most tires naturally lose air over time.
∙ Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
refer to “TPMS with tire inflation indi-
cator” in the “Starting and driving” sec-
tion of this manual.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WHEELS AND TIRES
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,
refer to “Driving safety precautions” in the
“Starting and driving” section of this
manual.
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 op-
erate this vehicle correctly may result in
loss of control or an accident.
For additional information, refer to “On-
pavement and off-road driving
precautions”, “Avoiding collision and roll-
over” and “Driving safety precautions” in
the “Starting and driving” section of this
manual.
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 prob-
lems 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 re-
mote insurance company monitoring, re-
mote vehicle diagnostics, telematics or en-
gine reprogramming, may cause

Roof-mounted curtain side-impact and roll-
over supplemental air bag system
This system can help cushion the impact
force to the head of occupants in front and
rear outboard seating positions in certain
side-impact or rollover collisions. In a side
impact, the curtain air bags are designed to
inflate on the side where the vehicle is im-
pacted. In a rollover, the curtain air bags are
designed to inflate and remain inflated for a
short time.
The SRS is designed tosupplementthe crash
protection provided by the driver and front
passenger seat belts and is not a substitute
for them. Seat belts should always be cor-
rectly worn and the occupant seated a suit-
able distance away from the steering wheel,
instrument panel and door finishers. For ad-
ditional information, refer to “Seat belts” in
this section.
Driver and passenger supplemental knee air
bags
This system can help cushion the impact
force to the driver’s and front passenger’s
knees in certain collisions. The SRS is designed to
supplementthe crash
protection provided by the driver and front
passenger seat belts and is not a substitute
for them. Seat belts should always be cor-
rectly worn and the occupant seated a suit-
able distance away from the steering wheel,
instrument panel and door finishers. For ad-
ditional information, refer to “Seat belts” in
this section.
The supplemental air bags operate only
when the ignition switch is placed in the ON
position.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.
1-44Safety—Seats, seat belts and supplemental restraint system
WARNING
∙ The front air bags ordinarily will not in-flate in the event of a side impact, rear
impact, rollover, or lower severity frontal
collision. Always wear your seat belts to
help reduce the risk or severity of injury in
various kinds of accidents.
∙ The front passenger air bag will not in- flate if the passenger air bag status light
is lit. For additional information, refer to
“Front passenger air bag and status
light” in this section. ∙ The seat belts and the front air bags are
most effective when you are sitting well
back and upright in the seat. The front air
bags inflate with great force. Even with
the INFINITI Advanced Air Bag System, if
you are unrestrained, leaning forward,
sitting sideways or out of position in any
way, you are at greater risk of injury or
death in a crash. You may also receive
serious or fatal injuries from the front air
bag if you are up against it when it in-
flates. Always sit back against the seat-
back and as far away as practical from
the steering wheel or instrument panel.
Always properly use the seat belts. ∙ The driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
INFINITI Advanced Air Bag System
monitors the severity of a collision and
seat belt usage then inflates the air bags
as needed. Failure to properly wear seat
belts can increase the risk or severity of
injury in an accident.
∙ The front passenger seat is equipped with an occupant classification sensor
(weight sensor) that turns the front pas-
senger air bag OFF under some condi-
tions. This sensor is only used in this seat.
Failure to be properly seated and wear-
ing the seat belt can increase the risk or
severity of injury in an accident. For addi-
tional information, refer to “Front pas-
senger air bag and status light” in this
section.
∙ Keep hands on the outside of the steering wheel. Placing them inside the steering
wheel rim could increase the risk that
they are injured when the front air bag
inflates.

Safety—Seats, seat belts and supplemental restraint system1-45
WARNING
To ensure proper operation of the passen-
ger’s INFINITI Advanced Air Bag System,
please observe the following items.
∙ Do not allow a passenger in the rear seatto push or pull on the seatback pocket.
∙ Do not place heavy loads heavier than 9.1 lbs. (4 kg) on the seatback, head
restraint/headrest or in the seatback
pocket.
∙ Make sure that there is nothing pressing against the rear of the seatback, such as a
child restraint installed in the rear seat or
an object stored on the floor.
∙ Make sure that there is no object placed under the front passenger seat.
∙ Make sure that there is no object placed between the seat cushion and the center
console or between the seat cushion and
the door. ∙ If a forward-facing child restraint is in-
stalled in the front passenger seat, do not
position the front passenger seat so the
child restraint contacts the instrument
panel. If the child restraint does contact
the instrument panel, the system may de-
termine the seat is occupied and the pas-
senger air bag may deploy in a collision.
Also the front passenger air bag status
light may not illuminate. For additional
information, refer to “Child restraints” in
this section.
∙ Confirm the operating condition with the front passenger air bag status light.
∙ If you notice that the front passenger air bag status light is not operating as de-
scribed in this section, get the occupant
classification system checked. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
∙ Until you have confirmed with a retailer that your passenger seat occupant clas-
sification system is working properly, po-
sition the occupants in the rear seating
positions. ∙ Do not position the front passenger seat
so it contacts the rear seat. If the front
seat does contact the rear seat, the air
bag system may determine a sensor mal-
function has occurred and the front pas-
senger air bag status light may illuminate
and the supplemental air bag warning
light may flash.
This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements un-
der U.S. regulations. It is also permitted in
Canada. All of the information, cautions and
warnings in this manual still apply and must
be followed.
The driver supplemental front-impact air bag
is located in the center of the steering wheel.
The front passenger supplemental front-
impact air bag is mounted in the dashboard
above the glove box. The front air bags are
designed to inflate in higher severity frontal
collisions, although they may inflate if the
forces in another type of collision are similar
to those of a higher severity frontal impact.
They may not inflate in certain frontal colli-
sions. Vehicle damage (or lack of it) is not
always an indication of proper front air bag
system operation.
