wheel size INFINITI M 2011 Owners Manual

child restraints and booster seats be properly
installed in a rear seat. If this is not possible,
the occupant classification sensor is designed
to operate as described above to turn the front
passenger air bag OFF for specified child re-
straints. Failing to properly secure child re-
straints and to use the ALR mode (child restraint
mode) may allow the restraint to tip or move in
an accident or sudden stop. This can also result
in the passenger air bag inflating in a crash
instead of being OFF. (See “CHILD RESTRAINTS”
earlier in this section for proper use and instal-
lation.)
If the front passenger seat is not occupied, the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object being detected by the occupant
classification sensor. Other conditions could
also result in air bag inflation, such as if a child
is standing on the seat, or if two children are on
the seat, contrary to the instructions in this
manual. Always be sure that you and all vehicle
occupants are seated and restrained properly.
Using the passenger air bag status light, you
can monitor when the front passenger air bag is
automatically turned OFF with the seat occu-
pied. The light will not illuminate when the front
passenger seat is unoccupied.If an adult occupant is in the seat but the
passenger air bag status light is illuminated
(indicating that the air bag is OFF), it could be
that the person is a small adult, or is not sitting
on the seat properly.
If a child restraint must be used in the front
seat, the passenger air bag status light may or
may not be illuminated, depending on the size
of the child and the type of child restraint being
used. If the passenger air bag status light is not
illuminated (indicating that the air bag might
inflate in a crash), it could be that the child
restraint or seat belt is not being used properly.
Make sure that the child restraint is installed
properly, the seat belt is used properly and the
occupant is positioned properly. If the passen-
ger air bag status light is still not illuminated,
reposition the occupant or child restraint in a
rear seat.
If the passenger air bag status light will not
illuminate even though you believe that the
child restraint, the seat belts and the occupant
are properly positioned, the system may be
sensing an unoccupied seat (in which case the
air bag is OFF). Your INFINITI retailer can check
that the system is OFF by using a special tool.
However, until you have confirmed with your
retailer that your air bag is working properly,
reposition the occupant or child restraint in a
rear seat.The INFINITI advanced air bag system and pas-
senger air bag status light will take a few
seconds to register a change in the passenger
seat status. However, if the seat becomes un-
occupied, the air bag status light will remain
off.
If a malfunction occurs in the front passenger
air bag system, the supplemental air bag warn-
ing light
, located in the meter and
gauges area will blink. Have the system
checked by an INFINITI retailer.
Other supplemental front-impact air
bag precautions
WARNING
● 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
bags inflate.

WARNING LIGHTS
All-Wheel Drive (AWD)
warning light (if so equipped)
Thewarning light comes on when the
ignition switch is pushed to ON. It turns off
soon after the engine is started.
If the Intelligent AWD system malfunctions, or
the diameter of the front and the rear wheels
are different, the warning light will either re-
main illuminated or blink. (See “INTELLIGENT
ALL-WHEEL DRIVE (AWD)” in the “5. Starting and
driving” section.)
CAUTION
● If the warning light comes on while driving
there may be a malfunction in the Intelligent
AWD system. Reduce the vehicle speed and
have your vehicle checked by an INFINITI re-
tailer as soon as possible.
● If the AWD warning light blinks on when you
are driving:
– blinks rapidly (about twice a second): Pull off the road in a safe area, and idle the
engine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning light turns
off, you can drive again. – blinks slowly (about once every 2 sec-
onds):
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the
same, tire pressure is correct and tires are
not worn.
● If the warning light is still on after the above
operations, have your vehicle checked by an
INFINITI retailer as soon as possible.
orAnti-lock Braking
System (ABS)
warning light
When the ignition switch is in the ON position,
the Anti-lock Braking System (ABS) warning
light illuminates and then turns off. This indi-
cates the ABS is operational.
If the ABS warning light illuminates while the
engine is running, or while driving, it may
indicate the ABS is not functioning properly.
Have the system checked by an INFINITI retailer.
If an ABS malfunction occurs, the anti-lock
function is turned off. The brake system then
operates normally, but without anti-lock assis-
tance. (See “BRAKE SYSTEM” in the “5. Starting
and driving” section.)

●If the light illuminates while driving, avoid
sudden steering maneuvers or abrupt brak-
ing, 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 in-
crease 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 ad-
justing 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 the 1 minute. Contact your
INFINITI retailer 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.CAUTION
● The TPMS is not a substitute for the regular
tire pressure check. Be sure to check the tire
pressure regularly.
● If the vehicle is being driven at speeds of less
than 16 MPH (25 km/h), the TPMS may not
operate correctly.
● Be sure to install the specified size of tires to
the four wheels correctly.
Master warning light
When the ignition switch is in the ON position,
the master warning light illuminates if any of
the following are displayed on the dot matrix
liquid crystal display:
● No key warning
● Low fuel warning
● Low washer fluid warning
● Parking brake release warning
● Door/trunk open warning
● Loose fuel cap warning (if so equipped)
● Check tire pressure warning (if so equipped)
● Intelligent key system warning
See “DOT MATRIX LIQUID CRYSTAL DISPLAY”
later in this section.
Preview Function warning
light (orange; if so equipped)
The light comes on if there is a malfunction in the
Brake Assist (with Preview Function) system.
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine, then resume driving.
If the indicator stays on, it may indicate that the
system is malfunctioning. Although the vehicle
is still driveable under normal conditions, have
the vehicle checked at an INFINITI retailer.
Seat belt warning light and
chime
The light and chime remind you to fasten seat
belts. The light illuminates whenever the igni-
tion switch is pushed to the ON position, and
will remain illuminated until the driver’s seat
belt is fastened. At the same time, the chime
will sound for about 6 seconds unless the
driver’s seat belt is securely fastened.
The seat belt warning light for the front passen-
ger will illuminate if the seat belt is not fastened
when the front passenger’s seat is occupied.
For 7 seconds after the ignition switch is in the
ON position, the system does not activate the
warning light for the front passenger.

and distances to objects with reference to the
bumper line
Aare displayed on the monitor.
Distance guide lines:
Indicate distances from the bumper.
● Red line
1: approx. 1.5 ft (0.5 m)
● Yellow line
2: approx. 3 ft (1 m)
● Green line
3: approx. 7 ft (2 m)
● Green line
4: approx. 10 ft (3 m)
Vehicle width guide lines
5:
Indicate the vehicle width when backing up. Predicted course lines
6:
Indicate the predicted course when backing up.
The predicted course lines will be displayed on
the monitor when the selector lever is in the “R”
(Reverse) position and the steering wheel is
turned. The predicted course lines will move
depending on how much the steering wheel is
turned and will not be displayed while the
steering wheel is in the neutral position.
HOW TO PARK WITH PREDICTED
COURSE LINES
WARNING
● Always turn and check that it is safe to park
your car before backing up. Always back up
slowly.
● Use the displayed lines as a reference. The
lines are highly affected by the number of
occupants, fuel level, vehicle position, road
condition and road grade.
● If the tires are replaced with different sized
tires, the predicted course line may not be
displayed correctly.
● On a snow-covered or slippery road, there
may be a difference between the predicted
course line and the actual course line. ●
If the battery is disconnected or becomes
discharged, the predicted course lines may
not be displayed correctly. If this occurs,
perform the following procedures.
– Drive the vehicle on a straight road for more than 5 minutes.
● The displayed lines will appear slightly off to
the right because the rearview camera is not
installed in the rear center of the vehicle.
● The distance guide line and the vehicle
width guide line should be used as a refer-
ence only when the vehicle is on a level
paved surface. The distance viewed on the
monitor is for reference only and may be
different than the actual distance between
the vehicle and displayed objects.
● When backing up the vehicle up a hill, ob-
jects viewed in the monitor are further than
they appear. When backing up the vehicle
down a hill, objects viewed in the monitor
are closer than they appear. Use the inside
mirror or glance over your shoulder to prop-
erly judge distances to other objects.
The vehicle width and predicted course lines are
wider than the actual width and course.

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 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
●
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).

Remember, drinking and driving don’t mix! And
that is true for drugs, too (over-the-counter,
prescription, and illegal drugs). Don’t drive if
your ability to operate your vehicle is impaired
by alcohol, drugs, or some other physical con-
dition.
INTELLIGENT ALL-WHEEL DRIVE (AWD)
DRIVING SAFETY PRECAUTIONS
WARNING
●Do not drive beyond the performance capa-
bility of the tires, even with Intelligent AWD
engaged. Accelerating quickly, sharp steer-
ing maneuvers or sudden braking may cause
loss of control.
● 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.
● This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in. ●
For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any D (Drive) or R (Re-
verse) position with the engine running. Do-
ing so may result in drivetrain damage or
unexpected vehicle movement which could
result in serious vehicle damage or personal
injury.
● Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer, (such as
the dynamometers used by some states for
emissions testing), or similar equipment
even if the other two wheels are raised off
the ground. Make sure you inform test facil-
ity personnel that your vehicle is equipped
with AWD before it is placed on a dynamom-
eter. Using the wrong test equipment may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
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.

●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. The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started. If any malfunction occurs in the Intelligent AWD
system while the engine is running, the warning
light will come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high power train oil temperature. The
driving mode may change to two-wheel drive. If
the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light goes
off after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning
light blink slowly (about once per two seconds).
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the same,
tire pressure is correct and tires are not worn.
If the warning light is blinking after the above
operation, have your vehicle checked by an
INFINITI retailer as soon as possible.

Warning light and display
When the Preview Function is not operating
properly, a chime sounds and the system warn-
ing 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 speci-
fied on the Tire and Loading Information
label. See “TIRE AND LOADING INFORMA-
TION LABEL” in the “9. Technical and con-
sumer information” section of this
manual.

●The steering wheel is forcibly turned beyond
its operation limits.
● The battery voltage is reduced.
Repeated steering maneuvers that may activate
the protection mechanism will damage the
4WAS system.
WARNING
The 4WAS system, although a sophisticated
device, cannot prevent accidents resulting
from careless or dangerous driving techniques.
Ultimately the responsibility for safety of self
and others rests in the hands of the driver.
Therefore only through attentive and careful
driving methods can the 4WAS system be fully
appreciated and safety optimized.
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 all-wheel drive
If you install snow tires, they must also be the
same size, brand, construction and tread pat-
tern on all four wheels.

2. Loosen each wheel nut one or two turnsby turning counterclockwise with the
wheel nut wrench. Do not remove the
wheel nuts until the tire is off the ground.
3. Carefully raise the vehicle until the tire clears the ground. To lift the vehicle,
securely hold the jack lever and rod with
both hands as shown above. Remove the
wheel nuts, and then remove the tire.Installing the spare tire
The T-type spare tire is designed for emergency
use. (See specific instructions under the head-
ing “WHEELS AND TIRES” in the “8. Maintenance
and do-it-yourself” section.)
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
Models equipped with different sized tires in
the front and rear:
When replacing a front tire, make sure that
the hole in the spare tire wheel is aligned
with the pin on the brake rotor.
