HEADLIGHTS
Replacing
Xenon headlight bulb :
WARNING
HIGH VOLTAGE
When xenon headlights are on, they produce a
high voltage. To prevent an electric shock,
never attempt to modify or disassemble. Al-
ways have your xenon headlights replaced at
an INFINITI retailer. For additional information,
see “HEADLIGHT AND TURN SIGNAL SWITCH” in
the “2. Instruments and controls” section.
Use the same number and wattage shown in the
following chart as originally installed.
If replacement is required, see an INFINITI re-
tailer.
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, contact an INFINITI retailer.

If you have a flat tire, see “FLAT TIRE” in the “6. In
case of emergency” section.
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
dot matrix liquid crystal 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 warn-
ing light” in the “2. Instruments and controls”
section, “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “6. In case of emergency” sec-
tion.
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 “Cold Tire Pressure”
heading. The Tire and Loading Informa-
tion 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 mod-
erate speeds. Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.
WARNING
●Improperly inflated tires can fail sud-
denly and cause an accident.
●The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. label. The vehicle weight
capacity is indicated on the Tire and
Loading Information label. Do not
load your vehicle beyond this capac-
ity. Overloading your vehicle may re-
sult in reduced tire life, unsafe operat-
ing conditions due to premature tire
failure, or unfavorable handling char-
acteristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
WHEELS AND TIRES
Maintenance and do-it-yourself8-31

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. (See “SPECIFICATIONS”
in the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.)
WARNING
●The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or ra-
dial), or tread patterns can adversely affect
the ride, braking, handling, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration, head-
light aim and bumper height. Some of these
effects may lead to accidents and could re-
sult in serious personal injury. ●
If the wheels are changed for any reason,
always replace with wheels which have the
same off-set dimension. Wheels of a differ-
ent off-set could cause premature tire wear,
degrade vehicle 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. See “WHEELS AND
TIRES” in the “9. Technical and consumer
information” section of this manual for
wheel off-set dimensions.
● 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 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment 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 repaired. Such
wheels or tires could have structural damage
and could fail without warning.
● The use of retread tire is not recommended. ●
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
All-Wheel Drive (AWD) models
CAUTION
●Always use tires of the same type, size,
brand, construction (bias, bias-belted or ra-
dial), 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 damage the transmission,
transfer case and differential gears.
● ONLY use spare tires specified for the AWD
model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the same size, brand, construction and tread
pattern. The tire pressure and wheel alignment
should also be checked and corrected as nec-
essary. Contact an INFINITI retailer.
Maintenance and do-it-yourself8-41

●If a methanol blend is used, it should contain
no more than 5% methanol (methyl alcohol,
wood alcohol). It should also contain a suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and corro-
sion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems. At this time, suffi-
cient data is not available to ensure that all
methanol blends are suitable for use in
INFINITI vehicles.
If any undesirable driveability problems such as
engine stalling or hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refueling.
Gasoline containing oxygenates can cause paint
damage.
E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square, orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed on
level roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.CAUTION
●
Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
● U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.

(French speakers).
To notify INFINITI of any safety concerns
please contact our Consumer Informa-
tion Centre toll free at 1-800-361-4792.A vehicle equipped with All-Wheel Drive (AWD)
should never be tested using a two wheel
dynamometer (such as the dynamometers used
by some states for emissions testing), or similar
equipment. Make sure you inform test facility
personnel that your vehicle is equipped with
AWD before it is placed on a dynamometer.
Using the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s inspection/
maintenance test readiness condition. Place the
ignition switch in the ON position without start-
ing the engine. If the Malfunction Indicator Light
(MIL) comes on steady for 20 seconds and then
blinks for 10 seconds, the I/M test condition is“not ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact a INFINITI retailer to set the “ready
condition” or to prepare the vehicle for testing.
