Rear center seat belt
The center seat belt buckle is identified by the
CENTER mark. The center seat belt tongue can
be fastened only into the center seat belt
buckle.
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 compatible
with the installed seat belts is available that
can be purchased. The extender adds approxi-
mately 8 in (200 mm) of length and may be
used for either the driver or front passengerseating position. See an INFINITI retailer for
assistance with purchasing an extender 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
the INFINITI seat belts.
● Adults and children who can use the stan-
dard seat belt should not use an extender.
Such unnecessary use could result in seri-
ous personal injury in the event of an
accident.
● Never use seat belt extenders to install child
restraints. If the child restraint is not se-
cured properly, the child could be seriously
injured in a collision or a sudden stop.
SEAT BELT MAINTENANCE
● To clean the seat belt webbing, apply a mild
soap solution or any solution recommended
for cleaning upholstery or carpets. 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 completely 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 buckles,
tongues, retractors, flexible wires and an-
chors work properly. If loose parts, deterio-
ration, cuts or other damage on the webbing
is found, the entire seat belt assembly
should be replaced.

WARNING LIGHTS
All-Wheel Drive (AWD)
warning 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 diam-
eter of the front and the rear wheels are differ-
ent, the warning light will either remain illumi-
nated or blink. (See “ALL-WHEEL DRIVE (AWD)”
in the “5. Starting and driving” section.)
CAUTION
● If the warning light comes on while driving
there may be a malfunction in the AWD sys-
tem. 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 second): 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 sec-
onds):
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 indi-
cates the ABS is operational.
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 assis-
tance. (See “BRAKE SYSTEM” in the “5. Starting
and driving” section.)
2-12Instruments and controls

●When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
● 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.
Low washer fluid warning

chime
The light and chime remind you to fasten seat
belts. The light illuminates whenever the igni-
tion switch is pushed to the ON position, and
will remain illuminated until the driver’s seat
belt is fastened. At the same time, the chime
will sound for about 6 seconds unless the
driver’s seat belt is securely fastened.
The seat belt warning light for the front passen-
ger will illuminate if the seat belt is not fastened
when the front passenger’s seat is occupied.
For 5 seconds after the ignition switch is in the
ON position, the system does not activate the

Predicted course lines6:
Indicate the predicted course when backing up.
The predicted course lines will be displayed on
the monitor when the selector lever is in the R
(Reverse) position and the 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 incor-
rectly, drive the vehicle on a straight road for
100 m at a speed of above 30 km/h.
● When the steering wheel is turned with the
ignition switch in the “ACC” position, the
predicted course lines may not be displayed
correctly.
● 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 refer-
ence 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 objects.
● When backing up the vehicle up a hill, ob-
jects 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 prop-
erly judge distances to other objects.
The vehicle width and predicted course lines are
wider than the actual width and course.

●Keep your engine tuned up. Malfunctions in
the ignition, fuel injection, or electrical sys-
tems 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 retailer.
● 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 recommended
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 pres-
sure 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 pres-
sure. 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 combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not beable to detect or signal low tire pressure as
intended. TPMS malfunctions 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
properly. 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.
Additional information
●
The TPMS does not monitor the tire pressure
of the spare tire.
● 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).
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h) to
activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
● The CHECK TIRE PRESSURE warning appears
in the vehicle information display when the
low tire pressure warning light is illuminated

DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces co-
ordination, delays reaction time and impairs
judgement. Driving after drinking alcohol in-
creases the likelihood of being involved in an
accident injuring yourself and others. Addition-
ally, if you are injured in an accident, alcohol
can increase the severity of the injury.
INFINITI is committed to safe driving. However,
you must choose not to drive under the influ-
ence of alcohol. Every year thousands of people
are injured or killed in alcohol-related acci-
dents. Although the local laws vary on what is
considered to be legally intoxicated, the fact is
that alcohol affects all people differently and
most people underestimate the effects of alco-
hol. Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs). Don’t drive if
your ability to operate your vehicle is impaired
by alcohol, drugs, or some other physical con-
dition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS (for AWD
models)
WARNING
●
Do not drive beyond the performance capa-
bility of the tires, even with AWD engaged.
Accelerating quickly, sharp steering maneu-
vers or sudden braking may cause loss of
control.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), and tread pattern on all four wheels.
Install tire chains on the rear wheels when
driving on slippery roads and drive carefully.
● This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in. ●
For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing 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 ve-
hicle 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 you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
Starting and driving5-7

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 opera-
tion, 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 po-
sition with the engine running. Doing so may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● Do not attempt to test an AWD equipped ve-
hicle 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 equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
CAUTION
● Do not operate the engine on a free roller
when any of the wheels are raised.

ALL-WHEEL DRIVE (AWD) (if so equipped)
5-74Starting and driving

Warning light and display
When the Preview Function is not operating
properly, the buzzer sounds and the system
warning light (orange) will come on.
Action to take :
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine and resume driving.
If the indicator stays on, it may indicate that the
Preview Function is malfunctioning (the brake is
operative). Although the Vehicle is still drive-
able under normal conditions, have the vehicle
checked at an INFINITI retailer.
How to handle the sensor
The sensor for the Preview Function is common
with Intelligent Cruise Control and is located
below the front bumper.
To keep the Preview Function operating prop-
erly, be sure to observe the following:
●Always keep the sensor clean. Wipe with a
soft cloth carefully so as not to damage the
sensor.
● Do not strike or damage the areas around
the sensor. Do not touch or remove the
screw located on the sensor. Doing so could
cause failure or malfunction. If the sensor is
damaged due to an accident, contact an
INFINITI retailer.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
sensor. This could cause failure or malfunc-
tion.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
● The Anti-lock Braking System (ABS) is a so-
phisticated device, but it cannot prevent ac-
cidents resulting from careless or dangerous
driving techniques. It can help maintain ve-
hicle control during braking on slippery sur-
faces. Remember that stopping distances on
slippery surfaces will be longer than on nor-
mal 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 brak-
ing 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 speci-
fied on the Tire and Loading Information
label. See “TIRE AND LOADING INFORMA-
TION LABEL” in the “9. Technical and con-
sumer information” section of this
manual.
