CHECKING INVERTER COOLANT LE-
VEL
Check the coolant level in the reservoir
when the engine and inverter are cold. If
the coolant level is below the MIN level
*B,
add coolant to the MAX level
*A.
If the inverter cooling system frequently
requires coolant, have it checked by an
INFINITI retailer.
CHANGING INVERTER COOLANT
An INFINITI ratailer can change the inverter
coolant. The service procedure can be
found in the INFINITI Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
. To avoid the danger of being scalded,
never change the coolant when the
inverter is hot.
. Never remove the cap when the inverter
is hot. Serious burns could be caused by
high pressure fluid escaping from the
inverter coolant reservoir.
. Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
. Keep coolant out of the reach of children
and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply 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

9-4Technical and consumer information
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.

ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
