3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 RPM)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
5. Open the hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check if the cooling fan is run-
ning. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing or the cooling fan does not run, stop
the engine.
WARNING
Be careful not to allow your hands, hair
or clothing to come into contact with,
or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time when the
coolant temperature is high.
7. After the engine cools down completely,
check the coolant level in the reservoir
tank with the engine running. Add coolant
to the reservoir tank, if necessary. Have
your vehicle repaired at an authorized
NISSAN dealer.
Inertia fuel shut-off switch
When the vehicle is involved in a collision,
the inertia fuel shutoff switch is designed to
automatically stop the flow of fuel to the
engine. The impact forces needed to trigger
the switch do not have to be great. Parking
lot bumping or road impacts (such as driving
over potholes) may trigger the switch.
Once the inertia fuel shutoff switch is trig-
gered, it must be reset before the engine
can be started. If your engine cranks but
does not start after a collision, take the
following steps to correctly reset the switch:

If the cooling system frequently requires
coolant, have it checked by an autho-
rized NISSAN dealer.
CHANGING ENGINE COOLANT
An authorized NISSAN dealer can change
the engine coolant. The service procedure
is found in NISSAN's service manual.
Improper servicing can result in reduced
heater performance and engine
overheating.
WARNING
cTo avoid danger of being scalded,
never change the coolant when the
engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Start the engine and let it idle until it
reaches operating temperature.
3. Turn the engine off.Wait a few 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 between the H
(High) and L (Low) marks. If the oil level
is below the L (Low) mark, remove the oil
filler cap and pour recommended oil
through the opening.Do not overfill.
6. Recheck the 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 sever-
ity of operating conditions.

and connections for leaks, looseness or
deterioration. If leaks are found, replace
them.
Fuel lines ÐCheck the fuel hoses, piping
and connections for leaks, looseness or
deterioration. Replace any damaged parts.
Fuel filter ÐIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-ther extremely low or extremely high, the
filter might become clogged. In such an
event, replace the filter immediately.
Engine coolant* ÐChanging engine cool-
ant can be performed by your NISSAN
dealer or procedures can be found in the
Service Manual. Improper air relief after
changing coolant can result in reduced
heater performance and overheating.
Engine oil & oil filter* ÐUnder normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.

of the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing may result in spark
knock, after-run, and/or overheating, which
may cause excessive fuel consumption or
engine damage. If any of the above symp-
toms are encountered, have your vehicle
checked at an authorized 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.
ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose engine oil with the
correct quality and viscosity to ensure sat-
isfactory engine life and performance. NIS-
SAN recommends the use of a low friction
oil (energy conserving oil) in order to im-
prove fuel economy and conserve energy.
Oils which do not have the specified quality
label should not be used as they could
cause engine damage.Only those engine oils with the American
Petroleum Institute (API) CERTIFICATION
MARK on the front of the container should
be used. This type of oil supersedes the
existing API SG, SH, or SJ and Energy
Conserving II categories.
If you cannot find engine oil with the API
CERTIFICATION MARK, use an API grade
SG/SH, Energy Conserving II or API grade
SJ, Energy Conserving oil. An oil with a
single designation SG or SH, or in combi-
nation with other categories (for example,
SG/CC or SG/CD) may also be used if one

Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and it is properly
installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle
if it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your rear view mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
cAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, first block the wheels
and apply the parking brake, and then
move the transmission shift selector le-
ver into the P (Park) position. If you move
the shift selector lever to the P (Park)
position before blocking the wheels and
applying the parking brake, transmission
damage could occur.
cWhen going down a hill, shift into a lowergear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine overloading and/or overheating.
cIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn the air
conditioner off. Coolant heat can be ad-
ditionally vented by opening the win-
dows, switching the fan control dial to
high and setting the temperature control
dial to the WARM position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for the first 500
miles (800 km) of the vehicle's life.
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn than
your vehicle wheels. To compensate for
this, make a larger than normal turning
radius during the turn.
cCrosswinds and rough roads adversely
