tire type INFINITI QX 2011 Owners Manual

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.

When the pressure reaches the designated
pressure, the horn beeps once.
● If the hazard indicator does not flash in
approximately 15 seconds after starting to
inflate the tire, it indicates that the Tire
Inflation Indicator is not operating.
● The TPMS will not activate the Tire Inflation
Indicator under the following conditions:
– If there is interference from an external device or transmitter
– The air pressure from the inflation device is not sufficient to inflate the tire
– There is a malfunction in the TPMS sys- tem
– There is a malfunction in the horn or hazard indicators
● If the Tire Inflation Indicator does not oper-
ate due to TPMS interference, move the
vehicle about 3 ft (1m) backward or forward
and try again.
If the Tire Inflation Indicator is not working, use
a tire pressure gauge.AVOIDING COLLISION AND ROLLOVER
WARNING
Failure to operate this vehicle in a safe and
prudent manner may result in loss of control or
an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle. As
with any vehicle, a loss of control could result in
a collision with other vehicles or objects, or
cause the vehicle to rollover, particularly if the
loss of control causes the vehicle to slide side-
ways. Be attentive at all times, and avoid
driving when tired. Never drive when under the
influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness). Always wear your seat belt
as outlined in the “SEAT BELTS” in the “1. Safety
— Seats, seat belts and supplemental restraint
system” section of this manual, and also in-
struct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash, an
unbelted or improperly belted person is signifi- cantly more likely to be injured or killed than a
person properly wearing a seat belt.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher roll-
over rate than other types of vehicles.
They have higher ground clearance than pas-
senger cars to make them capable of perform-
ing in a variety of on-pavement and off-road
applications. This gives them a higher center of
gravity than ordinary cars. An advantage of
higher ground clearance is a better view of the
road, allowing you to anticipate problems. How-
ever, they are not designed for cornering at the
same speeds as conventional passenger cars
any more than low-slung sports cars are de-
signed to perform satisfactorily under off-road
conditions. If at all possible, avoid sharp turns
or abrupt maneuvers, particularly at high
speeds. As with other vehicles of this type,
failure to operate this vehicle correctly may
result in loss of control or vehicle rollover. Seat
belts help reduce the risk of injury in collisions
and rollovers. In a rollover crash, an unbelted or
improperly belted person is significantly more
likely to be injured or killed than a person
properly wearing a seat belt.
Be sure to read “DRIVING SAFETY PRECAU-
TIONS” later in this section.
5-6Starting and driving

●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.
SSD0436
PUSH-BUTTON IGNITION SWITCH
5-10Starting and driving

The 4WD shift switch is used to select the 4WD
mode depending on the driving conditions.
There are 3 types of drive modes available,
AUTO, 4HI and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, AUTO, 4H and 4L.
You must depress the 4WD shift switch to select
4L, and the vehicle MUST be stationary and the
selector lever in the N (Neutral) position when
changing into or out of 4L.
WARNING
●When parking, apply the parking brake be-
fore stopping the engine and make sure that
the 4WD shift indicator is on and the ATP
warning light turns off. Otherwise, the ve-
hicle could unexpectedly move even if the
automatic transmission is in the P (Park)
position.
● The 4LO and 4HI indicators must stop blink-
ing and the 4LO or 4HI indicator must remain
illuminated or turn off before shifting the
transmission into gear. If the selector lever
is shifted from the N (Neutral) position to any
other gear while the 4LO and 4HI indicators
are blinking alternately, the vehicle may
move unexpectedly.
CAUTION
● Never shift the 4WD shift switch between 4L
and 4H while driving.
● The 4HI position provides greater traction.
Avoid excessive speed, as it will cause in-
creased fuel consumption and higher oil
temperatures, and could damage drivetrain
component. Speeds over 62 MPH (100 km/h)
in 4HI is not recommended.
● The 4LO position provides maximum trac-
tion. Avoid raising vehicle speed exces-
sively, as the maximum speed is approxi-
mately 31 MPH (50 km/h).
● When driving straight, shift the 4WD shift
switch to the AUTO or 4H position. Do not
move the 4WD shift switch when making a
turn or reversing.
● Do not shift the 4WD shift switch (between
AUTO and 4H) while driving on steep down-
hill grades. Use the engine brake and low
automatic transmission gears for engine
braking.
● Do not operate the 4WD shift switch (be-
tween AUTO and 4H) with the rear wheels
spinning. ●
Do not drive on dry hard surface roads in the
4HI or 4LO position. Driving on dry hard sur-
faces in 4HI or 4LO may cause unnecessary
noise and tire wear. INFINITI recommends
driving in the AUTO position under these
conditions.
● The 4WD transfer case may not be shifted
between 4HI and 4LO at low ambient tem-
peratures and the 4LO and 4HI indicators
may blink even when the 4WD shift switch is
shifted. After driving for a while you can
change the 4WD shift switch between 4H
and 4L.
When driving on rough roads,
● Drive carefully according to the road surface
conditions.
When the vehicle is stuck,
● Place stones or wooden blocks under the
tires to free the vehicle.
● Set the 4WD shift switch to 4H or 4L.
● If it is difficult to free the vehicle, repeat
forward and backward movement to increase
the movement.
● If the vehicle is stuck deep in mud, tire
chains may be effective.

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.
