2010 INFINITI M inflation pressure

The INFINITI Advanced Air Bag System has dual
stage inflators. The system monitors informa-
tion from the crash zone sensor, the Air bag
Control Unit (ACU), seat belt buckle switches,
occupant classification sensor (pressure sen-
sor) and passenger seat belt tension sensor.
Inflator operation is based on the severity of a
collision and seat belt usage for the driver. For
the front passenger, it additionally monitors the
weight of an occupant or object on the seat and
seat belt tension. Based on information from
the sensors, only one front air bag may inflate
in a crash, depending on the crash severity and
whether the front occupants are belted or un-
belted. Additionally, the front passenger air bag
may be automatically turned OFF under some
conditions, depending on the weight detected
on the passenger seat and how the seat belt is
used. If the front passenger air bag is OFF, the
passenger air bag status light will be illumi-
nated (if the seat is unoccupied, the light will
not be illuminated, but the air bag will be off).
(See ªFront passenger air bag and status lightº
later in this section for further details.) One
front air bag inflating does not indicate im-
proper performance of the system.
If you have any questions about your air bag
system, contact INFINITI or an INFINITI retailer. If
you are considering modification of your vehicle
due to a disability, you may also contactINFINITI. Contact information is contained in the
front of this Owner's Manual.
When a front air bag inflates, a fairly loud noise
may be heard, followed by release of smoke.
This smoke is not harmful and does not indicate
a fire. Care should be taken not to inhale it, as
it may cause irritation and choking. Those with
a history of a breathing condition should get
fresh air promptly.
Front air bags, along with the use of seat belts,
help to cushion the impact force on the head
and chest of the front occupants. They can help
save lives and reduce serious injuries. However,
an inflating front air bag may cause facial
abrasions or other injuries. Front air bags do
not provide restraint to the lower body.
Even with INFINITI advanced air bags, seat belts
should be correctly worn and the driver and
passenger seated upright as far as practical
away from the steering wheel or instrument
panel. The front air bags inflate quickly in order
to help protect the front occupants. Because of
this, the force of the front air bag inflating can
increase the risk of injury if the occupant is too
close to, or is against, the front air bag module
during inflation.
The front air bags deflate quickly after a colli-
sion.The front air bags operate only when the ignition
switch is in the ON position.
After pushing the ignition switch to the ON posi-
tion, the supplemental air bag warning light illu-
minates. The supplemental air bag warning light
will turn off after about 7 seconds if the system is
operational.

Other supplemental front-impact air
bag precautions
WARNING
c Do not place any objects on the steering
wheel pad or on the instrument panel. Also,
do not place any objects between any occu-
pant and the steering wheel or instrument
panel. Such objects may become dangerous
projectiles and cause injury if the front air
bag inflates.
c Immediately after inflation, several front air
bag system components will be hot. Do not
touch them; you may severely burn yourself.
c No unauthorized changes should be made to
any components or wiring of the supplemen-
tal air bag system. This is to prevent acciden-
tal inflation of the supplemental air bag or
damage to the supplemental air bag system. c
Do not make unauthorized changes to your
vehicle's electrical system, suspension sys-
tem or front end structure. This could affect
proper operation of the front air bag system.
c Tampering with the air bag system may re-
sult in serious personal injury. Tampering
includes changes to the steering wheel and
the instrument panel assembly by placing
material over the steering wheel pad and
above the instrument panel or by installing
additional trim material around the air bag
system.
c Modifying or tampering with the front pas-
senger seat may result in serious personal
injury. For example, do not change the front
seats by placing material on the seat cush-
ion or by installing additional trim material,
such as seat covers, on the seat that is not
specifically designed to assure proper air
bag operation. Additionally, do not stow any
objects under the front passenger seat or the
seat cushion and seatback. Such objects
may interfere with the proper operation of
the occupant classification sensor (pressure
sensor). c
No unauthorized changes should be made to
any components or wiring of the seat belt
system. This may affect the front air bag
system. Tampering with the seat belt system
may result in serious personal injury.
c Maintenance on and around the front air bag
system should be done by an INFINITI re-
tailer. Installation of electrical equipment
should also be done by an INFINITI retailer.
The Supplemental Restraint System (SRS)
wiring harnesses* should not be modified or
disconnected. Unauthorized electrical test
equipment and probing devices should not
be used on the air bag system.
c A cracked windshield should be replaced im-
mediately by a qualified repair facility. A
cracked windshield could affect the function
of the supplemental air bag system.
* The SRS wiring harness connectors are yellow and orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the front air bag system
and guide the buyer to the appropriate sections
in this Owner's Manual.

cKeep 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.
c Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-way
catalyst.
c Do not race the engine while warming it up.
c 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 your 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.

Additional information
cThe TPMS does not monitor the tire pressure
of the spare tire.
c 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).
c 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.
c 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. c
You can also check the pressure of all tires
(except the spare tire) on the display. (See
ªHOW TO USE INFO BUTTONº in the ª4.
Monitor, climate, audio, phone and voice
recognition systemsº section.)
After tire rotation is performed, tire pressure
will not be displayed in the actual tire posi-
tion. Drive the vehicle at over 25 MPH (40
km/h) for approximately 10 minutes to reset
the display.
For additional information, see ªLow tire pres-
sure warning lightº in the ª2. Instruments and
controlsº section and ªTIRE PRESSURE MONI-
TORING SYSTEM (TPMS)º in the ª6. In case of
emergencyº section.
WARNING
c 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 you have a flat tire, replace it
with a spare tire as soon as possible. (See
ªFLAT TIREº in the ª6. In case of emergencyº
section for changing a flat tire.)
c 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 approxi-
mately 1 minute. The light will remain on
after 1 minute. Contact your INFINITI retailer
as soon as possible for tire replacement
and/or system resetting.

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 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 ªLow tire pressure warn-
ing lightº in the ª2. Instruments and controlsº
section, ªTire Pressure informationº in the ª4.
Monitor, climate, audio, phone and voice rec-
ognition systemsº section, ªTIRE PRESSURE
MONITORING SYSTEM (TPMS)º in the ª5. Start-
ing and drivingº section and ªTIRE PRESSURE
MONITORING SYSTEM (TPMS)º in the ª6. In case
of emergencyº section.
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 ªCold Tire Pressureº
heading. The Tire and Loading Informa-
tion label is affixed to the driver side
center pillar. Tire pressures should be
checked regularly because:
cMost tires naturally lose air over time.
cTires 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. Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.
WARNING
cImproperly inflated tires can fail sud-
denly and cause an accident.
cThe 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.

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.
