2010 INFINITI QX TPMS

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will acti-
vate 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
(26 km/h) . For more details, refer to
“Warning/indicator lights and audible reminders”
in the “Instruments and controls” section, “Tire
pressure information” in the “Monitor, climate,
audio, phone and voice recognition systems”
section and “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” section.
WARNING
●If the low tire pressure warning light
illuminates 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 acci-
dent and could result in serious per-
sonal injury. Check the tire pressure for
all four tires. Adjust the tire pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. 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, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting. ●
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 be-
low:
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. Shift the transmission into P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel 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.

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)* When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation* Tires should be rotated every
7,500 miles (12,000 km) .
Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades* Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found later in this sec-
tion.
Accelerator pedal Check the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal. Automatic transmission P (Park) position
mechanism
On a fairly steep hill check that your
vehicle is held securely with the shift selector in
the P (Park) position without applying any brakes.
Brake pedal Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down fur-
ther than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, see an
INFINITI dealer immediately. Keep the floor mat
away from the pedal.
Brakes Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a fairly steep hill with only the parking brake
applied. If the parking brake needs adjustment,
see an INFINITI dealer.
Seats Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure they
operate smoothly and all latches lock securely in
every position. Check that the head restraints
move up and down smoothly and the locks hold
securely in all latched positions.
Seat belts Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.

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, one or more of your
tires is significantly under-inflated. The
system also displays pressure of all tires
(except the spare tire) on the display
screen by sending a signal from a sensor
that is installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(26 km/h) . Also, this system may not de-
tect a sudden drop in tire pressure (for
example a flat tire while driving) .
For more details, refer to “Low tire pres-
sure warning light” in the “Instruments and
controls” section, “Tire pressure informa-
tion” in the “Monitor, climate, audio, phoneand voice recognition systems” section,
“Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” sec-
tion, and “Flat tire” in the “In case of emer-
gency” section.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long dis-
tance trips. The recommended tire pres-
sure specifications are shown on the
F.M.V.S.S./C.M.V.S.S. certification label
or the Tire and Loading Information label
under the “Cold Tire Pressure” heading.
The Tire and Loading Information 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 moderate
speeds.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING
●The use of tires other than those recom-
mended or the mixed use of tires of
different brands, construction (bias,
bias-belted or radial) , or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-
tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.
● If your vehicle was originally equipped
with 4 tires that were the same size and
you are only replacing 2 of the 4 tires,
install the new tires on the rear axle.
Placing new tires on the front axle may
cause loss of vehicle control in some
driving conditions and cause an acci-
dent and personal injury. ●
If the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics and/or
interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear. Re-
fer to “Wheels and tires” in the “Techni-
cal and consumer information” section
of this manual for wheel off-set
dimensions.
● When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS. ●
Do not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
● The use of retread tires is not
recommended.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial) , and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.
