CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Run the engine until it reaches operat- ing temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the
range
*1. If the oil level is below*2,
remove the oil filler cap and pour
recommended oil through the opening.
Do not overfill
*3.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the break-
in period, depending on the severity of
operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insufficient
amount of oil can damage the engine, and such damage is not covered by warranty.
CHANGING ENGINE OIL AND FILTER

ENGINE OIL

Engine oil and filter
1. Place a large drain pan under the drainplug.
2. Remove the oil filler cap.
3. Remove the drain plug
*1with a
wrench and completely drain the oil.
CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
.Waste oil must be disposed of
properly.
.Check your local regulations.
4. (Perform steps 4 to 7 only when the engine oil filter change is needed.)
Loosen the oil filter
*2with an oil filter
wrench. Remove the oil filter by turning
it by hand.
5. Wipe the engine oil filter mounting surface with a clean rag.
CAUTION
Be sure to remove any old rubber gasket
remaining on the mounting surface of the engine. Failure to do so could lead to engine
damage.
6. Coat the gasket on the new filter with
clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten
additionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(14.7 to 20.5 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the
drain plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
CAUTION
The dipstick must be inserted in place to
prevent oil spillage from the dipstick hole
while filling the engine with oil.
See “Capacities and recommended
fuel/lubricants ”in the “9. Technical
and consumer information ”section for
drain and refill capacity. The drain and
refill capacity depends on the oil
temperature and drain time. Use these
specifications for reference only. Al-
ways use the dipstick to determine the
proper amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation

WARNING
. Prolonged and repeated contact with
used engine oil may cause skin cancer.
. Try to avoid direct skin contact with used
oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
. Keep used engine oil out of reach of
children.
When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.Use only Genuine NISSAN Matic S ATF.
Do not mix with other fluids.
. Using automatic transmission fluid other
than Genuine NISSAN Matic S ATF will
cause deterioration in driveability and
automatic transmission durability, and
may damage the automatic transmis-
sion, which is not covered by the INFINITI
new vehicle limited warranty.

3. Tighten cell plugs
*A.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, see “Jump
starting ”in the “6. In case of emergency ”
section. If the engine does not start by
jump starting, the battery may have to be
replaced. Contact an INFINITI retailer.CAUTION
. Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
. Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.

1. Visually inspect each belt for signs of
unusual wear, cuts, fraying or loosen-
ess. If the belt is in poor condition or
loose, have it replaced or adjusted by
an INFINITI retailer.
2. Have the belts checked regularly for condition and tension in accordance
with the maintenance schedule in your
“INFINITI Service and Maintenance
Guide ”.
WARNING
Be sure the engine and the ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to remove

ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than that specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not
operate, check for an open fuse.
1. Be sure the ignition switch is pushed to the OFF or LOCK position and the
headlight switch is turned to OFF.
2. Open the engine hood and remove the cover on the battery and the fuse/
fusible link holder.
3. Remove the fuse/fusible link holder cover.
4. Remove the fuse with the fuse puller.
FUSES

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-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 to
the 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 load.CAUTION
.
Your vehicle is not designed to run on E-
85 fuel. Using E-85 fuel in a vehicle not
specifically 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 identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region.

361-4792.A vehicle equipped with Intelligent 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 person-
nel 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 emission 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/mainte-
nance test readiness condition. Place the
ignition switch in the ON position without starting 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 an INFINITI retailer to set the
“ ready condition ”or to prepare the vehicle
for testing.
