ENGINE COOLANT
TEMPERATURE GAUGE
This gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture varies with the outside air temperature
and driving conditions.
CAUTION
If the gauge indicates engine coolant
temperature above the normal range,
stop the vehicle as soon as safely pos-
sible. If the engine is overheated, con-
tinued operation of the vehicle mayseriously damage the engine. See the
``In case of emergency'' section for
immediate action required.
FUEL GAUGE
This gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle remains in approximately
the same position even when the ignition
key is turned OFF.
The low fuel warning light comes on when
the amount of fuel in the tank is getting low.

CAUTION
cDo not use leaded gasoline. Depos-
its from leaded gasoline seriously
reduce the three-way catalyst's abil-
ity to help reduce exhaust pollut-
ants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the three-way cata-
lyst, causing it to overheat. Do not
keep driving if the engine misfires,
or if noticeable loss of performance
or other unusual operating condi-
tions are detected. Have the vehicle
inspected promptly by an authorized
NISSAN dealer.
cAvoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
cDo not race the engine while warm-
ing it up.
cDo not push or tow your vehicle to
start the engine.AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle.As with any vehicle, loss of
control could result in a collision with
other vehicles or objects, or cause the
vehicle to roll over, particularly if the
loss of control causes the vehicle to
slide sideways.Be attentive at all times,
and avoid driving when tired. Never drive
when under the influence of alcohol or
drugs (including prescription or over-the-
counter drugs which may cause drowsi-
ness). Always wear your seat belt as out-
lined in the ªSeats, restraints and
supplemental air bag systemsº section of
this manual, and also instruct your passen-
gers to do so.
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement.
Driving after drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in an
accident alcohol can increase the se-
verity of the injury.
NISSAN is committed to safe driving. How-
ever, you must choose not to drive under
the influence of alcohol. Every year thou-
sands of people are injured or killed in
alcohol related accidents. Although the local
laws vary on what is considered to be
legally intoxicated, the fact is alcohol affects
all people differently and most people un-
derestimate the effects of alcohol.
Remember, drinking and driving don't mix!
And that's true for drugs, too (over the
counter, prescription, and illegal drugs).
Don't drive if your ability to operate your

The power assisted steering is designed to
use a hydraulic pump, driven by the engine,
to aid steering.
If the engine stops or the drive belt breaks,
you still have control of the vehicle. How-
ever, much greater steering effort is
needed, especially in sharp turns and at low
speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be much harder to operate.The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
BRAKING PRECAUTIONS
Vacuum assisted brake
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal is required to stop the
vehicle, and the stopping distance is longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats the brakes,
wears out the brake linings and pads faster
and reduces fuel economy.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As aresult, your braking distance is longer and
the vehicle may pull to one side during
braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
WARNING
cWhile driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or acceleration could cause the
wheels to skid and result in an acci-
dent.
cIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
ANTI-LOCK BRAKE SYSTEM
(ABS)
The anti-lock brake system controls the
brakes at each wheel so the wheels do not
lock when braking abruptly or when braking

cMake sure the jumper cables do not
touch moving parts in the engine
compartment and that the clamps do
not contact any other metal.
5. Start the engine of the other vehicle and
let it run for a few minutes.
6. Keep the engine speed of the other ve-
hicle at about 2,000 RPM, and start the
engine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before
trying again.
7. After starting your engine, carefully dis-
connect the negative cable and then the
positive cable.
8. Replace the vent caps (if so equipped).
Be sure to dispose of the cloth used to
cover the vent holes as it may be con-
taminated with corrosive acid.
CAUTION
Automatic transmission models cannot
be push or tow started. This may cause
transmission or other vehicle damage.If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power,
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
cDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
cTo avoid the danger of being
scalded, never remove the radiator
cap while the engine is still hot.
When the radiator cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
cDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
gearshift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner switch. Open
all the windows, move the temperature
control dial to warm and fan control dial
to four.

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.
cAvoid direct skin contact with used
coolant. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
cKeep coolant out of reach of children
and pets.
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.

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.
NISSAN recommends the use of a low
friction oil (energy conserving oil) in order to
improve fuel economy and conserve en-
ergy. 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 in the
``NISSAN Service and Maintenance
Guide''.
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
9-18Technical and consumer information
ZX

affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and immedi-
ately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use overdrive.
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change fluid in the
transmission more frequently. For addi-
tional information see the ``NISSAN Ser-
vice and Maintenance Guide.''Department of Transportation (DOT) Qual-
ity Grades: All passenger car tires must
conform to Federal Safety Requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However,
relative tire performance depends on actual
driving conditions, and may vary signifi-
cantly, due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent the tire's ability to stop on wet pave-ment as measured under controlled condi-
tions, on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C
Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate
heat when tested under controlled condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material to degenerate, reducing
tire life. Excessive temperatures can lead to
sudden tire failure. Grade C corresponds to
a performance level which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A
and B represent higher levels of perfor-
mance on laboratory test wheels than the
minimum required by law.
