2011 INFINITI QX inflation pressure

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

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 dot matrix liquid crystal display when
the low tire pressure warning light is illumi-
nated and low tire pressure is detected. The
CHECK TIRE PRESSURE warning turns off
when the low tire pressure warning light
turns off.
The CHECK TIRE PRESSURE warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction. ●
Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires.
● You can also check the pressure of all tires
(except the spare tire) on the display screen.
The order of the tire pressure figures dis-
played on the screen does not correspond
with the actual order of the tire position. See
“TIRE PRESSURE information” in the “4.
Monitor, climate, audio, phone and voice
recognition systems” section.
For additional information, see “Low tire pres-
sure warning light” in the “2. Instruments and
controls” section and “TIRE PRESSURE MONI-
TORING SYSTEM (TPMS)” in the “6. In case of
emergency” 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 failure. Serious
vehicle damage could occur and may lead to
an accident and could result in serious per-
sonal injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the rec-
ommended 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. (See “FLAT TIRE” in the “6. In case of
emergency” section for changing a flat tire.)
● 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.
5-4Starting and driving

●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.
CAUTION
● The TPMS may not function properly when
the wheels are equipped with tire chains or
the wheels are buried in snow.
● Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals from
the tire pressure sensors, and the TPMS will
not function properly.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to
illuminate. Some examples are:
● Facilities or electric devices using similar
radio frequencies are near the vehicle.
● If a transmitter set to similar frequencies is
being used in or near the vehicle. ●
If a computer (or similar equipment) or a
DC/AC converter is being used in or near the
vehicle.

TPMS with Tire Inflation Indicator
When tire pressure is low, the low tire pressure
warning light illuminates.
This vehicle provides visual and audible signals
to help you inflate the tires to the recommended
COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the selector lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation:
1. Add air to the tire.
2. In a few seconds, the hazard indicators will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard
indicators stop flashing.
4. Perform the above steps for each tire.
● If the tire is over-inflated more than approxi-
mately 4 psi (30 kPa), the horn beeps and
the hazard indicators flash 3 times. To cor-
rect the pressure, push the core of the valve
stem on the tire briefly to release pressure.
Starting and driving5-5

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.

If you have a flat tire, see “FLAT TIRE” in the “6. In
case of emergency” section.
TIRE PRESSURE
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.
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).
For more details, see “Low tire pressure warn-
ing light” in the “2. Instruments and controls”
section, “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “6. In case of emergency” sec-
tion.
Tire inflation pressure
Check the pressure of the tires (includ-
ing the spare) often and always prior to
long distance trips. The recommended
tire pressure specifications are shown
on the Tire and Loading Information
label under the “Cold Tire Pressure”
heading. The Tire and Loading Informa-
tion label is affixed to the driver side
center pillar. Tire pressures should be
checked regularly because:
●Most tires naturally lose air over time.
●Tires can lose air suddenly when
driven over potholes or other objects
or if the vehicle strikes a curb while
parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.

TPMS also provides visual and audible
signals outside the vehicle for inflating
the tires to the recommended COLD tire
pressure. (See “TPMS with Tire Inflation
Indicator” in the “5. Starting and driv-
ing” section about the TPMS with Tire
Inflation Indicator.)
Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.
WARNING
●Improperly inflated tires can fail sud-
denly and cause an accident.
●The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on
the Tire and Loading Information la-
bel. Do not load your vehicle beyond
this capacity. Overloading your ve-
hicle may result in reduced tire life,
unsafe operating conditions due to
premature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident. Load-
ing beyond the specified capacity
may also result in failure of other ve-
hicle components.
●Before taking a long trip, or whenever
you heavily load your vehicle, use a
tire pressure gauge to ensure that the
tire pressures are at the specified
level.
●For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.

Checking the tire pressure
1.Remove the valve stem cap from the
tire.
2.Press the pressure gauge squarely
onto the valve stem. Do not press too
hard or force the valve stem side-
ways, or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gauge to eliminate this
leakage.
3.Remove the gauge.
4.Read the tire pressure on the gauge
stem and compare it to the specifica-
tion shown on the Tire and Loading
Information label.
5.Add air to the tire as needed. If too
much air is added, press the core of
the valve stem briefly with the tip of
the gauge stem to release pressure.
Recheck the pressure and add or re-
lease air as needed.
6.Install the valve stem cap.
7.Check the pressure of all other tires,
including the spare.
