REPLACING SPARK PLUGS
If replacement is required, see an INFINITI
retailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they
will last much longer. Follow the main-
tenance schedule in“INFINITI Service and
Maintenance Guide” , but do not reuse
them by cleaning or regapping. Always replace spark plugs with recom-
mended or equivalent ones.

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.

Contact an INFINITI retailer if checking or
replacement is required.If the brakes do not operate properly, have
the brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions,occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information,
see the maintenance log section of your
“INFINITI Service and Maintenance Guide”
for maintenance intervals.
BRAKE BOOSTER
Check the brake booster function as
follows:
1. With the engine off, depress and release the foot brake pedal more than
20 times. When the foot brake pedal
movement (distance of travel) remains
the same from one pedal application to
the next, continue on to the next step.
2. While depressing the foot brake pedal, start the engine.
3. With the foot brake pedal depressed, stop the engine. Keep the pedal de-
pressed for about 30 seconds.
4. Run the engine for 1 minute without depressing the foot brake pedal, then
turn it off. Depress the foot brake pedal

CAPACITIES AND RECOMMENDED FUEL/
LUBRICANTS

9-4Technical and consumer information
FUEL INFORMATION
VK56VD engine
INFINITI recommends the use of unleaded
premium gasoline with an octane rating of
at least 91 AKI (Anti-Knock Index) number
(Research octane number 96).
If unleaded premium gasoline is not
available, you may use unleaded regular
gasoline with an octane rating of at least
87 AKI number (Research octane number
91), but you may notice a decrease in
performance.
CAUTION
.Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
warranty coverage.
. Under no circumstances should a leaded
gasoline be used, because this will
damage the three-way catalyst.
. Do not use E-15 or E-85 fuel in your
vehicle. Your vehicle is not designed to
run on E-15 or E-85 fuel. Using E-15 or E-
85 fuel in a vehicle not specifically
designed for E-15 or E-85 fuel can adversely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the INFINITI new vehicle
limited warranty.
. U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter (WWFC)
specifications where it is available. Many
of the automobile manufacturers devel-
oped this specification to improve emis-
sion system and vehicle performance. Ask
your service station manager if the gaso-
line meets the World-Wide Fuel Charter
(WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing
reformulated gasolines. These gasolines
are specially designed to reduce vehicle
emissions. INFINITI supports efforts to-
wards cleaner air and suggests that you use reformulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your INFINITI
cannot be readily determined. If in doubt,
ask your service station manager.
If you use oxygenate-blend gasoline,
please take the following precautions as
the usage of such fuels may cause vehicle
performance problems and/or fuel system
damage.
.
The fuel should be unleaded and have
an octane rating no lower than that
recommended for unleaded gasoline.
. If an oxygenate-blend, excepting a
methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
. E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such

fuel is not covered by the INFINITI new
vehicle limited warranty.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient 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 experienced after using oxygenate-
blend fuels, immediately 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-15 fuel
E-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded gasoline. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
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. government
regulations require fuel 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.
Aftermarket fuel additives
INFINITI does not recommend the use of
any aftermarket fuel additives (Example:
fuel injector cleaner, octane booster, intake
valve deposit removers, etc.) which are
sold commercially. Many of these additives
intended for gum, varnish or deposit
removal may contain active solvent or
similar ingredients that can be harmful tothe fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, 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 misuse of the vehicle, for
which INFINITI is not responsible.
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 facility.
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 OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” earlier in this section. INFINITI
recommends the use of an energy conser-
ving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
on the front of the container. Oils which do
not have the specified quality label should
not be used as they could cause engine
damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
