SEAT BELT MAINTENANCE
.To clean the seat belt webbing, apply a
mild soap solution or any solution re-
commended 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 anchors work properly. If loose
parts, deterioration, cuts or other da-
mage on the webbing is found, the entire
seat belt assembly should be replaced.WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes tight.
This can occur even if the vehicle is
parked. Unbuckle the seat belt to release
the child.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available
from many other sources, including doctors,
teachers, government traffic safety offices,
and community organizations. Every child is
different, so be sure to learn the best way to
transport your child.
There are three basic types of child restraint
systems:
. Rear-facing child restraint
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s size. Generally, infants up to about 1 year
and less than 20 lbs (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for
children who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
seats are used to help position a vehicle lap/
shoulder belt on a child who can no longer
use a forward-facing child restraint.
WARNING
Infants and children need special protec-
tion. The vehicle’s seat belts may not fit
them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly
fitting seat belt could cause serious or
fatal injury. Always use appropriate
child restraints.
All U.S. states and Canadian provinces or
territories require the use of approved child
restraints for infants and small children. See
“Child restraints” (P.1-19).
A child restraint may be secured in the
vehicle by using either the LATCH (Lower
Anchor and Tethers for CHildren) system or
with the vehicle seat belt. See “Child re-
straints” (P.1-19) for more information.

Power steering warning light
Models with Direct Adaptive Steering :
When the ignition switch is in the ON
position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light stays on for a
few seconds and turns off. This indicates
that Direct Adaptive Steering is operational.
Drive the vehicle after the power steering
warning light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a
safe location and stop the vehicle. If the
power steering warning light turns off, you
can drive again. If the power steering
warning light continues to illuminate, it is
recommended you have Direct Adaptive Steering checked by an INFINITI retailer.
(See “Direct Adaptive Steering type” (P.5-
124).)
Models with electric power steering :
When the ignition switch is in the ON
position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light turns off. This
indicates the electric power steering is
operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the electric power steering is not
functioning properly and may need servicing.
It is recommended you have the electric
power steering checked by an INFINITI
retailer.
When the power steering warning light
illuminates with the engine running, the
power assist to the steering will cease
operation but you will still have control of
the vehicle. At this time, greater steering
efforts are required to operate the steering
wheel, especially in sharp turns and at low
speeds.
See “Electric power steering type” (P.5-124).

WARNING
.
If the tires are replaced with different
sized tires, the predictive course lines
may not be displayed correctly.
. On a snow-covered or slippery road,
there may be a difference between
the predictive course lines and the
actual course line.
. The displayed lines will appear
slightly off to the right because the
rearview camera is not installed in the
rear center of the vehicle.
. If the battery is disconnected or
becomes discharged, the predictive
course lines may be displayed incor-
rectly. If this occurs, please perform
the following procedures:
— Turn the steering wheel from lock to lock while the engine is running.
— Drive the vehicle on a straight road for more than 5 minutes.

Available views
WARNING
.The distance guide line and the
vehicle width line should be used as
a reference only when the vehicle is
on a paved, level surface. The dis-
tance viewed on the monitor is for
reference only and 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 af-
fected by the number of occupants,
fuel level, vehicle position, road con-
dition and road grade.
. If the tires are replaced with different
sized tires, the predictive course lines
and the bird’s-eye view may be dis-
played incorrectly.
. When driving the vehicle up a hill,
objects viewed in the monitor are
farther than they appear. When driv-
ing the vehicle down a hill, objects
viewed in the monitor are closer than
they appear.
. Objects in the rear view will appear
visually opposite compared to when viewed in the rear view and outside
mirrors.
. Use the mirrors or actually look to
properly judge distances to other
objects.
. The distance between objects viewed
in the rear view differs from actual
distance because a wide-angle lens is
used.
. On a snow-covered or slippery road,
there may be a difference between
the predictive course lines and the
actual course line.
. The vehicle width and predictive
course lines are wider than the actual
width and course.
. The displayed lines on the rear view
will appear slightly off to the right
because the rearview camera is not
installed in the rear center of the
vehicle.

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials away
from the exhaust system compo-
nents.
. 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 seriously reduce
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 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 in-
spected promptly. It is recommended
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 Mon-
itoring 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.
For models with run-flat tires, if the vehicle
is being driven with one or more flat tires,
the low tire pressure warning light will
illuminate continuously and a chime will
sound for 10 seconds. The flat tire warning
will also appear in the vehicle information
display. The chime will only sound at the first
indication of a flat tire, and the warning light
will illuminate continuously. When the flat
tire warning is activated, it is recommended
you have the system reset and the tire
checked and replaced if necessary by an
INFINITI retailer. Even if the tire is inflated
to the specified COLD tire pressure, the
warning light will continue to illuminate until
the system is reset by an INFINITI retailer.
Your vehicle can be driven for a limited time
on a flat tire. See “Run-flat tires” (P.8-31).

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 condition.
INTELLIGENT ALL-WHEEL
DRIVE (AWD) DRIVING SAFETY
PRECAUTIONS (AWD models)
WARNING
.Do not drive beyond the performance
capability of the tires, even with
Intelligent AWD engaged. Accelerat-
ing quickly, sharp steering maneuvers
or sudden braking may cause loss of
control.
. 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.
. 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
attempt 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 dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing), or similar equip-
ment 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 unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
. When a wheel is off the ground due
to an unlevel surface, do not spin the
wheel excessively.
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 shift lever to the
P (Park) position.

PUSH-BUTTON IGNITION SWITCH

If any malfunction occurs in the Intelligent
All-Wheel Drive (AWD) system while the
engine is running, warning messages appear
in the vehicle information display.
JVS0228M
If the “AWD Error” warningappears, there
may be a malfunction in the Intelligent AWD
system. Reduce vehicle speed and have the
system checked as soon as possible. It is
recommended you visit an INFINITI retailer
for this service.
The “AWD High Temp.” (high temperature)
warning
may appear while trying to free a stuck vehicle due to increased oil tempera-
ture. The driving mode may change to Two-
Wheel Drive (2WD). If this warning is
displayed, 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.
The “Tire Size Incorrect” warning
may
appear if there is a large difference between
the diameters of front and rear wheels. Pull
off the road in a safe area, with the engine
idling. Check that all tire sizes are the same,
that the tire pressure is correct and that the
tires are not excessively worn.
If any warning message continues to be
displayed, have your vehicle checked as soon
as possible. It is recommended you visit an
INFINITI retailer for this service.
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.

faces will be longer than on normal
surfaces even with ABS. Stopping
distances 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
“Tire and loading information la-
bel” (P.10-13) of this manual.
— For detailed information, see “Wheels and tires” (P.8-25) of
this manual.
The Anti-lock Braking System (ABS) controls
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 preventing 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 dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
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 pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a mal-function, 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. It is recommended you visit
an INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating
properly. However, the pulsation may indi-
cate that road conditions are hazardous and
extra care is required while driving.

SONAR INDICATOR
When the corner of the vehicle moves closer
to an object, the corner sensor indicator
appears on the upper display.
When the center of the vehicle moves close
to an object, the center sensor indicator
appears on the upper display.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before insert-
ing it into the key hole or use the Intelligent
Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-3) or
“Intercooler cooling system” (P.8-5).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly. For
additional information, see “Battery” (P.8-
11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system” (P.8-3).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended you consult an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
Tire chains may be used. For details, see
“Tire chains” (P.8-33) of this manual.
Intelligent All-Wheel Drive (AWD)
models
If you install snow tires, they must also be
the same size, brand, construction and tread
pattern on all four wheels.
