Seat belt hook
When the seat belt is not in use and when
folding down the rear seats, hook the rear
seat belts on the seat belt hooks.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap/shoulder
belt and fasten it, an extender that is compat-
ible with the installed seat belts is available
for purchase. The extender adds approxi-
mately 8 in (200 mm) of length and may be
used for the driver and front passenger seat-
ing positions.
It is recommended that you visit an INFINITI
retailer for assistance with purchasing an ex-
tender if an extender is required.
WARNING
• Only INFINITI seat belt extenders, made
by the same company which made the
original equipment seat belts, should be
used with INFINITI seat belts.
• Adults and children who can use the
standard seat belt should not use an ex-
tender. Such unnecessary use could re-
sult in serious personal injury in the event
of an accident.
• Never use seat belt extenders to install
child restraints. If the child restraint is
not secured properly, the child could be
seriously injured or killed in a collision or
a sudden stop.
SEAT BELT MAINTENANCE
• To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpet.
Then wipe with a cloth and allow the seat
belts to dry in the shade. Do not allow the
seat belts to retract until they are com-
pletely dry.
• If dirt builds up in the shoulder belt guide of
the seat belt anchors, the seat belts may
retract slowly. Wipe the shoulder belt guide
with a clean, dry cloth.
• Periodically check to see that the seat belt
and the metal components, such as buck-
les, tongues, retractors, flexible wires and
anchors, work properly. If loose parts, de-
terioration, cuts or other damage on the
webbing is found, the entire seat belt as-
sembly should be replaced.

WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
• If the light does not illuminate with the
ignition switch placed in the ON position,
have the vehicle checked as soon as pos-
sible. It is recommended that you visit an
INFINITI retailer for this service.
• If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible. Driv-
ing with under-inflated tires may perma-
nently damage the tires and increase the
likelihood of tire failure. Serious vehicle
damage could occur and may lead to an
accident and could result in serious per-
sonal injury or death. Check the tire pres-
sure for all four tires. Adjust the tire
pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Information label located in the driver’s
door opening to turn the low tire pres-
sure warning light OFF. If the light still illuminates while driving after adjusting
the tire pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
•
When using a wheel without the TPMS
such as the spare tire, the TPMS will not
function and the low tire pressure warning
light will flash for approximately 1 minute.
The light will remain on after 1 minute.
Have your tires replaced and/or TPMS
system reset as soon as possible. It is rec-
ommended that you visit an INFINITI re-
tailer for these services.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly. •
If the vehicle is being driven at speeds of
less than 16 mph (25 km/h), the TPMS
may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gal-
lons (11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for
20 seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance test.
For additional information, see “Readiness for
Inspection/Maintenance (I/M) test” (P. 10-35).

AWD High Temp. Stop vehicle
This warning may appear while trying to free
a stuck vehicle due to increased oil tempera-
ture. The driving mode may change to
2-Wheel Drive (2WD). If this warning is dis-
played, stop the vehicle with the engine idling,
as soon as it is safe to do so. Then if the
warning turns off, you can continue driving.
AWD Tire Size Incorrect: See
Owner’s Manual
This warning may appear if there is a large
difference between the diameters of the
front and rear wheels. Pull off the road in a
safe area, with the engine idling. Check that
all the tire sizes are the same, that the tire
pressure is correct and that the tires are not
excessively worn.
CVT (AT) Malfunction Service now
This warning appears when there is a prob-
lem with the CVT system. If this warning
comes on, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
CVT (AT) hot Power reduced
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with heavy
loads, such as when towing a trailer), engine
power and, under some conditions, vehicle
speed will be decreased automatically to re-
duce the chance of transmission damage.
Vehicle speed can be controlled with the ac-
celerator pedal, but the engine and vehicle
speed may be reduced.
WARNING
When the high fluid temperature protec-
tion mode operation occurs, vehicle speed
may be gradually reduced. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
necessary, pull to the side of the road at a
safe place and allow the transmission to
return to normal operation; or have it re-
paired if necessary.
Engine hot Power reduced
This engine has a high fluid temperature pro-
tection mode. If the fluid temperature be-
comes too high (for example, climbing steep
grades in high temperatures with heavy
loads, such as when towing a trailer), engine
power and, under some conditions, vehicle
speed will be decreased automatically to re-
duce the chance of engine damage. Vehicle
speed can be controlled with the accelerator
pedal, but the engine and vehicle speed may
be reduced.
WARNING
When the high fluid temperature protec-
tion mode operation occurs, vehicle speed
may be gradually reduced. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
necessary, pull to the side of the road at a
safe place and allow the engine to return to

WARNING
• The distance guide lines and the vehicle
width lines should be used as a reference
only when the vehicle is on a paved, level
surface. The apparent distance viewed
on the monitor may be different than the
actual distance between the vehicle and
displayed objects.
• Use the displayed lines and the bird’s-
eye view as a reference. The lines and the
bird’s-eye view are greatly affected by
the number of occupants, cargo, fuel
level, vehicle position, road condition
and road grade.
• If the tires are replaced with different
sized tires, the predicted course lines and
the bird's-eye view may be displayed
incorrectly.
• When driving the vehicle up a hill, objects
viewed in the monitor are further than
they appear. When driving the vehicle
down a hill, objects viewed in the monitor
are closer than they appear. •
Objects in the rear view will appear visu-
ally opposite compared to when viewed
in the monitor and outside mirrors.
• Use the mirrors or actually look to prop-
erly judge distances to other objects.
• On a snow-covered or slippery road,
there may be a difference between the
predicted course lines and the actual
course line.
• The vehicle width and predicted course
lines are wider than the actual width and
course.
• The displayed lines will appear slightly
off to the right, because the rearview
camera is not installed in the rear center

•Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst's ability to
help reduce exhaust pollutants.
• Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over rich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-
ommended that you visit an INFINITI
retailer for this service.
• 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
SYSTEM (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 Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all 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 driv-
er’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 combined
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 se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion 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.
Starting and driving5-5

•If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds.
Your INFINITI vehicle has a higher center
of gravity than a passenger car. The ve-
hicle is not designed for cornering at the
same speeds as passenger cars. Failure
to operate this vehicle correctly could re-
sult 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 front
wheels when driving on slippery roads
and drive carefully.
• Be sure to check the brakes immediately
after driving in mud or water. For addi-
tional information, see “Brake precau-
tions” (P. 5-140).
• 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. For additional information, see
“Additional maintenance items for se-
vere operating conditions” (P. 9-7).INTELLIGENT ALL-WHEEL
DRIVE (AWD) DRIVING SAFETY
PRECAUTIONS (if so equipped)
WARNING
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• 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 front
wheels when driving on slippery roads
and drive carefully.
• This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
• For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any D
(Drive) or R (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 dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious vehicle dam-
age or personal injury.
• When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
