2011 INFINITI QX tire pressure

The IBA system will remain in the last ON or OFF
state it was left in until it is manually changed
by pressing the IBA OFF switch.
Illumination of the IBA OFF indicator light with-
out a beep sound is an indication that the IBA
system is temporarily unavailable. It will occur
under the following conditions:
– When driving into a strong light (for example,sunlight)
– When the 4WD shift switch is in the 4H or 4L position (for 4WD models)
The IBA OFF indicator light will turn off when the
system returns to its normal operating condi-
tions.
For the sensor maintenance, see “Sensor main-
tenance” earlier in this section.CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle.
Failure to follow these recommendations may
result in shortened engine life and reduced en-
gine performance.
● Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(805 km). ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
● Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
● Select a gear range suitable to road condi-
tions.
● Avoid unnecessary prolonged engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated at the correct pres-
sure. Improper tire pressure will increase
wear and waste fuel.
● Make sure the front wheels are properly
aligned. Improper alignment will cause pre-
mature tire wear and lower fuel economy.
● Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
● When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.

In the event of a roadside emergency, Roadside
Assistance Service is available to you. Please
refer to your Warranty Information Booklet
(U.S.) or Warranty & Roadside Assistance Infor-
mation Booklet (Canada) for details.To shut off the engine in an emergency situation
while driving perform the following procedure:
●
Rapidly push the push-button ignition
switch 3 consecutive times, or
● Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING SYSTEM
(TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires except the spare. When the
low tire pressure warning light is lit and the
CHECK TIRE PRESSURE warning (if so equipped)
appears in the dot matrix liquid crystal display,
one or more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and warn
you of it by the low tire pressure warning light.
This system will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h). For
more details, see “WARNING/INDICATOR LIGHTS
AND AUDIBLE REMINDERS” in the “2. Instru-
ments and controls” section, “TIRE PRESSURE
information” in the “4. Monitor, climate, audio,
phone and voice recognition systems” section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section.

WARNING
●If the low tire pressure warning light illumi-
nates or LOW PRESSURE information is dis-
played on the monitor screen 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. Driving with under-
inflated tires may permanently damage the
tires and increase the likelihood of tire fail-
ure. Serious vehicle damage could occur and
may lead to an accident and could result in
serious personal injury. 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 to turn the low tire pressure warning
light OFF. If the light still illuminates while
driving after adjusting the tire pressure, a
tire may be flat. If you have a flat tire, replace
it with a spare tire as soon as possible.
● 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.
● Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the selector lever to
the P (Park) position.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from
traffic and clear of the vehicle.
WARNING
●Make sure the parking brake is securely ap-
plied and the automatic transmission is in
the P (Park) position.
● Never change tires when the vehicle is on a
slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for professional
road assistance.

CAUTION
Do not insert the jack rod straight as it is de-
signed to be inserted at an angle as shown.
9. Seat the T-shaped end of the jack rod intothe T-shaped opening of the spare wheel
winch. Apply pressure to keep the jack
rod engaged in the spare wheel winch
and turn the jack rod counterclockwise to
lower the spare wheel. 10. Once the spare wheel is completely low-
ered, remove the jack rod and reach
under the vehicle to remove the hanging
plate.
11. Carefully slide the spare wheel from un- der the rear of the vehicle.
After preparing the spare tire, to remove the
rod, pull out the rod while moving the rod to the
right and left with the screw of the extension
facing the side.
CAUTION
When storing the wheel, make sure that the
hanging plate is in the center of the wheel and
then lift it up into the storage area.

WARNING
●Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become
loose or come off. This could cause an
accident.
● Do not use oil or grease on the wheel studs or
nuts. This could cause the nuts to become
loose.
● Retighten the wheel nuts when the vehicle
has been driven for 600 miles (1,000 km)
(also in cases of a flat tire, etc.).
● As soon as possible, tighten the wheel nuts
to the specified torque with a torque wrench.
Wheel nut tightening torque: 98 ft-lb (133 N·m)
The wheel nuts must be kept tightened to speci-
fication at all times. It is recommended that
wheel nuts be tightened to specifications at
each lubrication interval. ●
Adjust tire pressure to the COLD pressure.
COLD pressure:
After the vehicle has been parked for three
hours or more or driven less than 1 mile (1.6
km).
COLD tire pressures are shown on the Tire
and Loading Information label affixed to the
driver side center pillar.
After adjusting tire pressure to the COLD tire
pressure, the display of the tire pressure infor-
mation may show higher pressure than the
COLD tire pressure after the vehicle has been
driven more than 1 mile (1.6 km). This is be-
cause the tire pressurizes as the tire tempera-
ture rises. This does not indicate a system
malfunction.
Stowing the damaged tire and tools
1. Securely store the damaged tire, jack and tools in the storage area.
2. Close the cargo floor cover.
3. Replace the cargo floor board.
4. Close the lift gate.
WARNING
Always make sure that the spare tire and jack-
ing equipment are properly secured after use.
Such items can become dangerous projectiles
in an accident or sudden stop.
If needed Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty Information
Booklet (Canada).

WAXING
Regular waxing protects the paint surface and
helps retain new vehicle appearance. Polishing
is recommended to remove built-up wax residue
and to avoid a weathered appearance before
reapplying wax.
An INFINITI retailer can assist you in choosing
the proper product.
●Wax your vehicle only after a thorough wash-
ing. Follow the instructions supplied with
the wax.
● Do not use a wax containing any abrasives,
cutting compounds or cleaners that may
damage the vehicle finish.
Machine compound or aggressive polishing on
a base coat/clear coat paint finish may dull the
finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust, in-
sects, and tree sap as quickly as possible from
the paint surface to avoid lasting damage or
staining. Special cleaning products are avail-
able at an INFINITI retailer or any automotive
accessory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This will
prevent dirt and salt from building up and
causing the acceleration of corrosion on the
underbody and suspension. Before the winter
period and again in the spring, the underseal
must be checked and, if necessary, re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows, do
not use sharp-edged tools, abrasive cleaners or
chlorine-based disinfectant cleaners. They
could damage the electrical conductors, radio
antenna elements or rear window defroster
elements.
WHEELS
Wash the wheels when washing the vehicle to
maintain their appearance.
● Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
● Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
● INFINITI recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.
CAUTION
Do not use abrasive cleaners when washing the
wheels.
