CHECKING ENGINE COOLANT LEVELCheck the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
MIN
*2, open the reservoir cap and add
coolant up to the MAX
*1
level. If the reservoir
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 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 a NISSAN
dealer.
CHANGING ENGINE COOLANTMajor cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN 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 chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

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
engine running to avoid discharging
the vehicle battery.
The variable voltage control system measures
the amount of electrical discharge from the
battery and controls voltage generated by the
generator.VARIABLE VOLTAGE CONTROL

vehicles.
If any undesirable driveability problems such as
engine stalling or hard hot starting are experi-
enced after using oxygenate-blend fuels, im-
mediately 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 fuelE-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 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 additivesNISSAN 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 tipsUsing 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 a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN 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 a
NISSAN dealer 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.
