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 severely
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 steer-
ing wheel and the instrument panel as-
sembly 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 passen- ger 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 cush-
ion and seatback. Such objects may inter-
fere with the proper operation of the oc-
cupant classification sensor (weight
sensor).
∙ No unauthorized changes should be made to any components or wiring of the seat
belt system. This may affect the front air
bag system. Tampering with the seat belt
system may result in serious personal
injury.

∙ It is recommended that you visit anINFINITI retailer for work on and around
the front air bag. It is also recommended
that you visit an INFINITI retailer for in-
stallation of electrical equipment. The
Supplemental Restraint System (SRS)
wiring harnesses* should not be modified
or disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag system.
∙ A cracked windshield should be replaced immediately by a qualified repair facility.
A cracked windshield could affect the
function of the supplemental air bag
system.
*The SRS wiring harness connectors are yel-
low and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the front air bag
system and guide the buyer to the appropri-
ate sections in this Owner’s Manual.
Front seat-mounted side-impact
supplemental air bag and roof-
mounted curtain side-impact and
rollover supplemental air bag
systems
The side air bags are located in the outside of
the seatback of the front seats. The curtain
air bags are located in the side roof rails in
both rows. All of the information, cautions
and warnings in this manual apply and must
be followed. The side air bags and curtain air
bags are designed to inflate in higher severity
side collisions, although they may inflate if
the forces in another type of collision are similar to those of a higher severity impact.
They are designed to inflate on the side
where the vehicle is impacted. They may not
inflate in certain side collisions.
Curtain air bags are also designed to inflate in
certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off-
roading) may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always an
indication of proper side air bag and curtain
air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard, fol-
lowed by release of smoke. This smoke is not
harmful and does not indicate a fire. Care
should be taken not to inhale it, as it may
cause irritation and choking. Those with a
history of a breathing condition should get
fresh air promptly.
Side air bags, along with the use of seat belts,
help to cushion the impact force on the chest
of the front occupants. Curtain air bags help
to cushion the impact force to the head of
occupants in the front and rear outboard
seating positions in all rows. They can help
save lives and reduce serious injuries. How-
ever, an inflating side air bag or curtain air

Safety—Seats, seat belts and supplemental restraint system1-59

bag may cause abrasions or other injuries.
Side air bags and curtain air bags do not
provide restraint to the lower body.
The seat belts should be correctly worn and
the driver and front passenger seated upright
as far as practical away from the side air bag.
Rear seat passengers should be seated as far
away as practical from the door finishers and
side roof rails. The side air bags and curtain
air bags inflate quickly in order to help protect
the occupants. Because of this, the force of
the side air bags and curtain air bags inflating
can increase the risk of injury if the occupant
is too close to, or is against, these air bag
modules during inflation. The side air bag will
deflate quickly after the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags oper-
ate 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.WARNING
∙ Do not place any objects near the seat-back of the front seats. Also, do not place
any objects (an umbrella, bag, etc.) be-
tween the front door finisher and the
front seat. Such objects may become
dangerous projectiles and cause injury if
a side air bag inflates.
∙ Right after inflation, several side air bag and curtain air bag system components
will be hot. Do not touch them; you may
severely burn yourself.
∙ No unauthorized changes should be made to any components or wiring of the side
air bag and curtain air bag systems. This
is to prevent damage to or accidental in-
flation of the side air bag and curtain air
bag systems.
∙ Do not make unauthorized changes to your vehicle’s electrical system, suspen-
sion system or side panel. This could af-
fect proper operation of the curtain air
bag systems. ∙ Tampering with the side air bag system
may result in serious personal injury. For
example, do not change the front seats
by placing material near the seatbacks or
by installing additional trim material,
such as seat covers, around the side air
bag.
∙ It is recommended that you visit an INFINITI retailer for work on and around
the side air bag and curtain air bag. It is
also recommended that you visit an
INFINITI retailer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag or curtain
air bag systems.
*The SRS wiring harness or connectors are
yellow or orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the side air bags
and curtain air bag system and guide the
buyer to the appropriate sections in this
Owner’s Manual.
1-60Safety—Seats, seat belts and supplemental restraint system

∙ No unauthorized changes should be madeto any components or wiring of the knee
air bag system. This is to prevent damage
to or accidental inflation of the knee air
bag system.
∙ Do not make unauthorized changes to your vehicle’s electrical system or sus-
pension system. This could affect proper
operation of the knee air bag system.
∙ Tampering with the knee air bag system may result in serious personal injury. For
example, do not change the driver knee
bolster or install additional trim material
around the knee air bag.
∙ It is recommended that you visit an INFINITI retailer for work on and around
the knee air bag. It is also recommended
that you visit an INFINITI retailer for in-
stallation of electrical equipment. The
SRS wiring harnesses* should not be
modified or disconnected. Unauthorized
electrical test equipment and probing de-
vices should not be used on the knee air
bag system. *The SRS wiring harness or connectors are
yellow or orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the knee air bag
system and guide the buyer to the appropri-
ate sections in this manual.
Seat belt with pretensioner(s) (front
and rear outboard seats)
WARNING
∙ The pretensioner(s) cannot be reused af-
ter activation. They must be replaced to-
gether with the retractor and buckle as a
unit.
∙ If the vehicle becomes involved in a colli- sion but pretensioner(s) are not acti-
vated, be sure to have the pretensioner
system checked and, if necessary, re-
placed. It is recommended that you visit
an INFINITI retailer for this service.
∙ No unauthorized changes should be made to any components or wiring of the pre-
tensioner system. This is to prevent dam-
age to or accidental activation of the pre-
tensioner(s). Tampering with the
pretensioner system may result in serious
personal injury. ∙ It is recommended that you visit an
INFINITI retailer for work on and around
the pretensioner system. It is also recom-
mended that you visit an INFINITI re-
tailer for installation of electrical equip-
ment. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
∙ If you need to dispose of the pretension- er(s) or scrap the vehicle, it is recom-
mended that you visit an INFINITI re-
tailer for this service. Incorrect disposal
procedures could cause personal injury.
The pretensioner system may activate with
the supplemental air bag system in certain
types of collisions. Working with the seat belt
retractor, the pretensioner(s) help tighten the
seat belt when the vehicle becomes involved
in certain types of collisions, helping to re-
strain front seat occupants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt anchor
affixed to the floor of the vehicle. These seat
belts are used the same way as conventional
seat belts.
When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it
1-62Safety—Seats, seat belts and supplemental restraint system

may cause irritation and choking. Those with
a history of a breathing condition should get
fresh air promptly.
After the pretensioner(s’) activation, load lim-
iters allow the seat belt to release webbing (if
necessary) to reduce forces against the chest.
The supplemental air bag warning light
is used to indicate malfunctions in the preten-
sioner system. For additional information, re-
fer to "Supplemental air bag warning light" in
this section. If the operation of the supple-
mental air bag warning light indicates there is
a malfunction, have the system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When selling your vehicle, we request that
you inform the buyer about the pretensioner
system and guide the buyer to the appropri-
ate sections in this Owner’s Manual.1. SRS air bag warning labels (located on

WARNING
∙ Do not leave children or adults whowould normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acciden-
tally injure themselves or others through
inadvertent operation of the vehicle.
Also, on hot, sunny days, temperatures in
a closed vehicle could quickly become
high enough to cause severe or possibly
fatal injuries to people or animals.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; they con-tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death.
∙ If you suspect that exhaust fumes are en- tering the vehicle, drive with all windows
fully open, and have the vehicle inspected
immediately. ∙ Do not run the engine in closed spaces
such as a garage.
∙ Do not park the vehicle with the engine running for any extended length of time.
∙ Keep the rear vent windows, liftgates, doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
∙ If electrical wiring or other cable connec- tions must pass to a trailer through the
seal on the liftgate or the body, follow
the manufacturer’s recommendation to
prevent carbon monoxide entry into the
vehicle.
∙ The exhaust system and body should be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service. b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
∙ The exhaust gas and the exhaust systemare very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
∙ Do not stop or park the vehicle over flam- mable materials such as dry grass, waste
paper or rags. They may ignite and cause
a fire.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-4Starting and driving

∙ Check your hitch, trailer wiring harnessconnections, and trailer wheel lug nuts
after 50 miles (80 km) of travel and at
every break.
∙ When launching a boat, don’t allow the water level to go over the exhaust tail
pipe or rear bumper.
∙ Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more frequently.
For additional information, refer to the “Do-
it-yourself” section of this manual.
FLAT TOWING FOR ALL–WHEEL
DRIVE VEHICLE (if so equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.
CAUTION
∙ Failure to follow these guidelines can re- sult in severe transmission damage.
∙ Never flat tow your All-wheel drive (AWD) vehicle.
∙ DO NOT tow your All-wheel drive (AWD) vehicle with any wheels on the ground.
Doing so may cause serious and expen-
sive damage to the powertrain.
∙ For emergency towing procedures refer to “Towing recommended by INFINITI” in
the “In case of emergency” section of this
manual.
FLAT TOWING FOR FRONT
WHEEL DRIVE VEHICLE (if so
equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.
CAUTION
∙ Failure to follow these guidelines can re-sult in severe transmission damage.
∙ Whenever flat towing your vehicle, al- ways tow forward, never backward.
∙ Never tow your front wheel drive vehicle with the front tires on the ground. Doing
so may cause serious and expensive dam-
age to the powertrain.
∙ DO NOT tow your front wheel drive con- tinuously variable transmission vehicle
with all four wheels on the ground (flat
towing). Doing so WILL DAMAGE inter-
nal transmission parts due to lack of
transmission lubrication.
