WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.1. Visually inspect the belt for signs of unusual
wear, cuts, fraying or looseness. If the belt is
in poor condition or is loose, have it replaced
or adjusted. It is recommended that you visit
an INFINITI retailer for this service.
2. Have the belt checked regularly for condi- tion and tension in accordance with the
maintenance schedule found in your Main-
tenance and schedules section of this
manual.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-tippedA
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in the Mainte-
nance and schedules section of this manual. Do
not service iridium-tipped spark plugs by clean-
ing or regapping.
● Always replace spark plugs with rec-
ommended or equivalent ones.

WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect socket
can damage the spark plugs.
If replacement is required, it is recommended that
you visit an INFINITI retailer for this service.
WARNING
● Operating the engine with the air
cleaner filter off can cause you or others
to be burned. The air cleaner filter not
only cleans the intake air, it also stops
the flame if the engine backfires. If the
air cleaner is not installed and the en-
gine backfires, you could be burned.
Never drive with the air cleaner filter off.
Be cautious working on the engine
when the air cleaner is off. ●
Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
To remove the filter from the air cleaner, push the
tabs
Aand pull the cover upward.
The viscous paper type filter element should not be
cleaned and reused. Replace the air filter accord-
ing to the maintenance log shown in the Mainte-
nance and schedules section of this manual.
When replacing the air filter, wipe the inside of the
air cleaner housing and the cover with a damp cloth.
NOTE:
After installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips
A.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry of air-
borne dust and pollen particles and reduces
some objectionable outside odors. The filter is
located behind the glove box. Refer to the Main-
tenance and schedules section of this manual
for change intervals.
If replacement is required, it is recommended that
you visit an INFINITI retailer for this service.

If checking or replacement is required, it is rec-
ommended that you visit an INFINITI retailer for
this service. If the brakes do not operate properly, it is recom-
mended that you have the brakes checked. It is
recommended that you visit an INFINITI retailer
for this service.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
Have your brake system checked if the
brake pedal height does not return to nor-
mal. It is recommended that you visit an
INFINITI retailer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.

ing brake inspections, refer to the appropriate
maintenance schedule information in the Main-
tenance and schedules section of this manual.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should con-
tact the electric medical equipment
manufacturer for the possible influ-
ences before use.
This vehicle is equipped with the Tire Pres-
sure Monitoring System (TPMS) . It moni-
tors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit and the “Tire Pressure Low – Add
Air” warning appears in the vehicle informa-
tion display, 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.

WHEELS AND TIRES

The TPMS will activate only when the
vehicle is driven at speeds above 16 mph
(25 km/h). Also, this system may not de-
tect a sudden drop in tire pressure (for
example a flat tire while driving) .
For additional information, refer to “Low tire
pressure warning light” in the “Instruments
and controls” section, “Tire Pressure Moni-
toring System (TPMS)” in the “Starting and
driving” section and “Flat tire” in the “In
case of emergency” section of this manual.
Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long dis-
tance trips. The recommended tire pressure
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.
TPMS with Tire Inflation Indicator pro-
vides visual and audible signals outside
the vehicle for inflating the tires to the
recommended COLD tire pressure. For
additional information, refer to “TPMS
with Tire Inflation Indicator” in the “Start-
ing and driving” section of this manual.
Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.WARNING
● Improperly inflated tires can fail
suddenly 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 vehicle weight capacity
is indicated on the Tire and Load-
ing Information label. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may re-
sult in reduced tire life, unsafe op-
erating conditions due to prema-
ture tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident.
Loading beyond the specified ca-
pacity may also result in failure of
other vehicle 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 re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.
