The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See the “9. Main-
tenance and schedules” section of this
manual for maintenance intervals. When
replacing the filter, wipe the inside of the
air cleaner housing and the cover with a
damp cloth.
WARNING
.
Operating the engine with the air cleaner
removed can cause you or others to be
burned. The air cleaner not only cleans
the air, it stops flame if the engine
backfires. If it isn’t there, and the engine
backfires, you could be burned. Do not
drive with the air cleaner removed, and
be careful when working on the engine
with the air cleaner removed.
.
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.

CLEANING
If your windshield is not clear after using
the windshield washer or if a wiper blade
chatters when running, wax or other
material may be on the blade or wind-
shield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form
when rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild
detergent. Then rinse the blade with clear
water. If your windshield is still not clear
after cleaning the blades and using the
wiper, replace the blades.
Worn windshield wiper blades can damage
the windshield and impair driver vision.

HEADLIGHTS
Replacing
Fog may temporarily form inside the lens of
the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
it is recommended you visit an INFINITI
retailer for servicing.
Xenon headlight bulb:
If replacement is required, it is recom-
mended you visit an INFINITI retailer for
this service.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon headlights
replaced by a certified service technician.

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 appears on the vehicle
information 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
warning light” (P.2-16), “Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-3).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al-
ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on 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
under inflation, may adversely affect
tire life and vehicle handling.

WARNING
.
Improperly inflated tires can
fail suddenly and cause an
accident.
.
The Gross Vehicle Weight rat-
ing (GVWR) is located on the F.
M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the
Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Over-
loading your vehicle may re-
sult in reduced tire life, unsafe
operating conditions due to
premature tire failure, or un-
favorable handling character-
istics and could also lead to a
serious accident. Loading be-
yond the specified capacity
may also result in failure of
other vehicle components.
.
Before taking a long trip, or
whenever you heavily load
your vehicle, use a tire pres-
sure gauge to ensure that the
tire pressures are at the spe-
cified level.
.
For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the War-
ranty Information Booklet.

Checking the tire pressure
1. Remove the valve stem cap from
the tire.
2. P r e s s t h e p r e s s u r e g a u g e
squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage.
3. Remove the gauge.
4. Read the tire pressure on the
gauge stem and compare it to
the specification shown on the
Tire and Loading Information la-
bel.
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 release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other
tires, including the spare.

Example
TIRE LABELING
Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.
SDI1606
Example
*
1 Tire size (example: P215/60R16
94H)
1. P: The “P” indicates the tire is
designed for passenger vehicles.
(Not all tires have this informa-
tion.)
2. Three-digit number (215): This
number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.
3. Two-digit number (60): This num-
ber, known as the aspect ratio,
gives the tire’s ratio of height to
width.
4. R: The “R” stands for radial.
5. Two-digit number (16): This num-
ber is the wheel or rim diameter in
inches.
6. Two- or three-digit number (94):
This number is the tire’s load
index. It is a measurement of
how much weight each tire can
support. You may not find this
information on all tires because it
is not required by law.
7. H: Tire speed rating. You should
not drive the vehicle faster than
the tire speed rating.
