2012 INFINITI FX wheel size

1-46Safety—Seats, seat belts and supplemental restraint system
may or may not be illuminated, depending
on the size of the child and the type of
child restraint being used. If the passenger
air bag status light is not illuminated
(indicating that the air bag might inflate
in a crash), it could be that the child
restraint or seat belt is not being used
properly. Make sure that the child restraint
is installed properly, the seat belt is used
properly and the occupant is positioned
properly. If the passenger air bag status
light is still not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not
illuminate even though you believe that the
child restraint, the seat belts and the
occupant are properly positioned, the
system may be sensing an unoccupied
seat (in which case the air bag is OFF). Your
INFINITI retailer can check that the system
is OFF by using a special tool. However,
until you have confirmed with your retailer
that your air bag is working properly,
reposition the occupant or child restraint
in a rear seat.
The INFINITI Advanced Air Bag System and
passenger air bag status light will take a
few seconds to register a change in the
passenger seat status. However, if the seat becomes unoccupied, the air bag status
light will remain off.
If a malfunction occurs in the front
passenger air bag system, the supplemen-
tal air bag warning light
, located in the
meter and gauges area will blink. Have the
system checked by an INFINITI retailer.
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
become dangerous projectiles and cause
injury if the front air bags inflate.
. Do not place objects with sharp edges
on the seat. Also, do not place heavy
objects on the seat that will leave
permanent impressions in the seat. Such
objects can damage the seat or occupant
classification sensors (weight sensors).
This can affect the operation of the air
bag system and result in serious perso-
nal injury. .
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensors. This can also affect the
operation of the air bag system and
result in serious personal injury.
. 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 air bag system may
result in serious personal injury. Tamper-
ing includes changes to the steering
wheel and the instrument panel assem-
bly by placing material over the steering
wheel pad and above the instrument
panel or by installing additional trim

light (AWD models)
Thewarning light comes on when the
ignition switch is pushed to ON. It turns off
soon after the engine is started.
If the AWD system malfunctions, or the
diameter of the front and the rear wheels
are different, the warning light will either
remain illuminated or blink. (See “All-
Wheel Drive (AWD)” (P.5-75).)
CAUTION
.If the warning light comes on while
driving there may be a malfunction in
the AWD system. Reduce the vehicle
speed and have your vehicle checked by
an INFINITI retailer as soon as possible.
. If the AWD warning light blinks on when
you are driving:
—blinks rapidly (about twice a sec-
ond):
Pull off the road in a safe area, and
idle the engine. The driving mode will
change to 2WD to prevent the AWD
system from malfunctioning. If the warning light turns off, you can drive
again.
—blinks slowly (about once every 2
seconds):
Pull off the road in a safe area, and
idle the engine. Check that all tire
sizes are the same, tire pressure is
correct and tires are not worn.
. If the warning light is still on after the
above operations, have your vehicle
checked by an INFINITI retailer as soon
as possible.
orAnti-lock Braking
System (ABS) warning light
When the ignition switch is in the ON
position, the Anti-lock Braking System
(ABS) warning light illuminates and then
turns off. This indicates the ABS is opera-
tional.
If the ABS warning light illuminates while
the engine is running, or while driving, it
may indicate the ABS is not functioning
properly. Have the system checked by an
INFINITI retailer.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then operates normally, but without anti-
lock assistance. (See
“Brake system”(P.5-
78).)

in the Brake Assist (with Preview Function)
system.
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, then resume driving.
If it is not possible to set the ICC system or
the Preview Function warning light re-
mains on, it may indicate that the system
is malfunctioning. Although the vehicle is
still driveable under normal conditions,
have the vehicle checked at an INFINITI
retailer.
Rear Active Steer warning light
(if so equipped)
If the light comes on while the engine is
running, it may indicate that there is a
malfunction with the Rear Active Steer
portion of the steering system. Have the
system checked by an INFINITI retailer.

steering wheel is turned. The predicted
course lines will move depending on how
much the steering wheel is turned and will
not be displayed while the steering wheel
is in the neutral position.
HOW TO PARK WITH PREDICTED
COURSE LINES
WARNING
. Always turn and check that it is safe to
park your car before backing up. Always
back up slowly.
. Use the displayed lines as a reference.
The lines are highly affected by the
number of occupants, fuel level, vehicle
position, road condition and road grade.
. If the tires are replaced with different
sized tires, the predicted course line
may not be displayed correctly. .
On a snow-covered or slippery road,
there may be a difference between the
predicted course line and the actual
course line.
. If predicted course lines are displayed
incorrectly, drive the vehicle on a
straight road for 110 yd (100 m) at a
speed of above 20 MPH (30 km/h).
. The displayed lines will appear slightly
off to the right because the rearview
camera is not installed in the rear center
of the vehicle.
. The distance guide line and the vehicle
width guide line should be used as a
reference only when the vehicle is on a
level paved surface. The distance viewed
on the monitor is for reference only and
may be different than the actual distance
between the vehicle and displayed ob-
jects.
. When backing up the vehicle up a hill,
objects viewed in the monitor are further
than they appear. When backing up the
vehicle down a hill, objects viewed in the
monitor are closer than they appear. Use
the inside mirror or glance over your
shoulder to properly judge distances to
other objects.

cause a fire.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical systems can cause overrich fuel
flow into the three-way catalyst, causing
it to overheat. Do not keep driving if the
engine misfires, or if noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
. Do not race the engine while warming it
up.
. Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and it is the driver’
s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

states for emissions testing), or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury. (AWD
models)
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
. Accelerating quickly, sharp steering
maneuvers or sudden braking may cause
loss of control.
. If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your vehicle has a higher center of
gravity than a conventional passenger
car. The vehicle is not designed for
cornering at the same speeds as con-
ventional passenger cars. Failure to
operate this vehicle correctly could
result in loss of control and/or a rollover
accident.
. Always use tires of the same type, size, brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
. Be sure to check the brakes immediately
after driving in mud or water. See “Brake
system” (P.5-78) for wet brakes.
. Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or sideways,
you could be injured.
. Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See the maintenance
information in the “INFINITI Service and
Maintenance Guide”.
. Spinning the rear wheels on slippery
surfaces may cause the AWD warning
light to flash and the AWD system to
automatically switch from the AWD
mode to the 2WD mode. This could
reduce traction. Be especially careful
when towing a trailer. (AWD models)WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (The engine will stop when the
ignition switch is pushed 3 consecutive
times or the ignition switch is pushed and
held for more than 2 seconds.) If the engine
stops while the vehicle is being driven, this
could lead to a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the selector lever
to the P (Park) position.
PUSH-BUTTON IGNITION SWITCH

The AWD warning light is located in the
meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON
position. It turns off soon after the engine
is started.If any malfunction occurs in the AWD
system while the engine is running, the
warning light will come on.
The warning light may blink rapidly (about
twice per second) while trying to free a
stuck vehicle due to high power train oil
temperature. The driving mode may change
to two-wheel drive. If the warning light
blinks rapidly during operation, stop the
vehicle with the engine idling in a safe
place immediately. Then if the light goes
off after a while, you can continue driving.
A large difference between the diameters
of front and rear wheels will make the
warning light blink slowly (about once per
two seconds). Pull off the road in a safe
area, and idle the engine. Check that all
tire sizes are the same, tire pressure is
correct and tires are not worn.
If the warning light is blinking after the
above operation, have your vehicle
checked by an INFINITI retailer as soon as
possible.
WARNING
.
For AWD equipped vehicles, do not
attempt to raise two wheels off the ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing) or similar
equipment even if the other two wheels
are raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
CAUTION
.Do not operate the engine on a free
roller when any of the wheels are raised.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remember
that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front of
you. Ultimately, the driver is responsible
for safety.
. Tire type and condition may also affect
braking effectiveness.
—When replacing tires, install the
specified size of tires on all four
wheels.
—When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. See “Tireand loading information label”
(P.9-
13) of this manual.
—For detailed information, see “Wheels and tires” (P.8-32) of this
manual.
The Anti-lock Braking System (ABS) con-
trols the brakes so the wheels do not lock
during hard braking or when braking on
slippery surfaces. The system detects the
rotation speed at each wheel and varies
the brake fluid pressure to prevent each
wheel from locking and sliding. By pre-
venting each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels
from locking up. Steer the vehicle to avoid
obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric pumps, hydraulic solenoids and a
computer. The computer has a built-in
diagnostic feature that tests the system
each time you start the engine and move
the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsa-
tion in the brake pedal. This is normal and
does not indicate a malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS
warning light on the instrument panel.
The brake system then operates normally,
but without anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked by an INFINITI retailer.
