CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below MIN
*2, open the reservoir
tank cap and add coolant up to the MAX
*1level. If the reservoir tank is empty, check
the coolant level in the radiator when the
engine is cold. If there is insufficient
coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir tank up to the
MAX level
*1.
Tighten the cap securely after adding
engine coolant. If the cooling system requires coolant
frequently, have it checked by an INFINITI
retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be
performed by an INFINITI retailer. The
service procedures can be found in the
appropriate INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
.
To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
. Never remove the radiator cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.
. 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 reach of children and
pets.
Engine coolant must be disposed of
properly. Check your local regulations.

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.
Inverter coolant must be disposed of
properly. 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
*1. If the oil level is below*2,

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 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
