Storing 3rd row seat belt buckles
Before folding down the seat, put the buckles in
the storage of the seat cushion to avoid drop-
ping it under the seat cushion.
Shoulder belt height adjustment (for
front seats and 2nd row seats)
The shoulder belt anchor height should be
adjusted to the position best for you. (See
“PRECAUTIONS ON SEAT BELT USAGE” earlier in
this section.)
To adjust, push the button
A, and then move
the shoulder belt anchor to the desired posi-
tion, so that the belt passes over the center of
the shoulder. The belt should be away from
your face and neck, but not falling off of your
shoulder. Release the adjustment button to lock
the shoulder belt anchor into position.
WARNING
● After adjustment, release the adjustment
button and try to move the shoulder belt
anchor up and down to make sure it is se-
curely fixed in position.
● The shoulder belt anchor height should be
adjusted to the position best for you. Failure
to do so may reduce the effectiveness of the
entire restraint system and increase the
chance or severity of injury in an accident.
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 passenger
seating position. See an INFINITI retailer for
assistance with purchasing an extender if an
extender is required.

Safety — Seats, seat belts and supplemental restraint system1-27

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. 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 differ-
ent, so be sure to learn the best way to trans-
port 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 out-
grow rear-facing child restraints 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.

HOW TO SEE EACH VIEW
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 distance viewed on the monitor is for
reference only and may be different than the
actual distance between the vehicle and dis-
played objects.
● Use the displayed lines and the bird-eye
view as a reference. The lines and the bird-
eye view are greatly 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 predictive course lines and the
bird-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. Use the mirrors or actually look
to properly judge distances to other objects.
The vehicle width and predictive course lines
are wider than the actual width and course.

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 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 all 4 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 be
able 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.
Starting and driving5-3

●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.
● Be sure to check the brakes immediately af-
ter driving in mud or water. See “BRAKE SYS-
TEM” later in this section 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 sur-
faces may cause the 4WD warning light to
flash. The 4WD system may also automati-
cally switch from the 4WD mode to the 2WD
mode. This could reduce traction. Be espe-
cially careful when towing a trailer (4WD
models).WARNING
Do not operate the push-button ignition switch
while driving the vehicle except in an emer-
gency. (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.
OPERATING RANGE FOR ENGINE
START FUNCTION
The operating range for starting the engine
inside the vehicle
1is shown in the illustra-
tion.
● If the Intelligent Key is on the instrument
panel, cargo area, inside the glove box or
door pocket, or the corner of interior com-
partment, it may not be possible to start the
engine.
● If the Intelligent Key is near the door or door
glass outside the vehicle, it may be possible
to start the engine.

Warning light and display
When the Preview Function is not operating
properly, the chime 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 specified on
the Tire and Loading Information label. See
“TIRE AND LOADING INFORMATION LABEL”
in the “9. Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “WHEELS AND TIRES” in the “8. Maintenance and
do-it-yourself” section of this manual.

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 inserting 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 protec-
tion. For additional information, see “ENGINE
COOLING SYSTEM” in the “8. Maintenance and
do-it-yourself” section.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see “BATTERY” in the “8. Mainte-
nance and do-it-yourself” section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING SYS-
TEM” in the “8. Maintenance and do-it-yourself”
section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. 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.
Consult an INFINITI retailer 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” in the “8. Maintenance and do-it-
yourself” section of this manual.
For four-wheel drive
If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
●A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
● Wet ice (32°F, 0°C and freezing rain), very
cold snow or ice can be slick and very hard to
drive on. The vehicle will have much less
traction or “grip” under these conditions.
Try to avoid driving on wet ice until the road
is salted or sanded.
● Whatever the condition, drive with caution.
Accelerate and slow down with care. If accel-
erating or downshifting too fast, the drive
wheels will lose even more traction.
