parking the vehicle on a level surface, with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and (if so equipped) clutch fluid
levels* ÐMake sure that the brake and
clutch fluid level are between the MIN and
MAX lines on each reservoir.
Power steering fluid level* and lines Ð
Check the level when the fluid is cold and
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Automatic transmission fluid level* Ð
Check the level after putting the shift selec-
tor lever in P (Park) with the engine idling at
operating temperature.Engine coolant level* ÐCheck the cool-
ant level when the engine is cold.
Radiator and hoses ÐCheck the front of
the radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts* ÐMake sure the drive
belts are not frayed, worn, cracked or oily.
Battery* ÐCheck the fluid level in each
cell. It should be between the MAX and MIN
lines.
Exhaust system ÐMake sure there are no
cracks, holes, loose joints or supports. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected by
a qualified individual. (See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.)
Underbody ÐThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines

maximum total weight (load) limit speci-
fied for the vehicle.
cGAWR (Gross Axle Weight Rating) -
maximum weight (load) limit specified for
the front or rear axle.
DETERMINING VEHICLE LOAD
CAPACITY
The load capacity of this vehicle is determined
by weight, not by available cargo space. For
example, a luggage rack, bike carrier, cartop
carrier or similar equipment does not increase
load carrying capacity of your vehicle.
To determine vehicle load capacity:
Vehicle weight can be determined by using
a commercial-grade scale, found at places
such as a truck stop, gravel quarry, grain
elevator, or a scrap metal recycling facility.
1)
Determine the curb weight of your vehicle.
2) Compare the curb weight amount to the
GVWR specified for your vehicle to de-
termine how much more weight your
vehicle can carry.
3) After loading (cargo and passengers),
re-weigh your vehicle to determine if
either GVWR or GAWR for your vehicle
is exceeded. If GVWR is exceeded, re-move cargo as necessary. If either the
front or rear GAWR is exceeded, shift the
load or remove cargo as necessary.
LOADING TIPS
cThe GVW must not exceed GVWR or
GAWR as specified on the FMVSS Cer-
tification Label.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
WARNING
c
Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
cDo not load your vehicle any heavier
than the GVWR or the maximum
front and rear GAWRs. If you do,
parts of your vehicle can break, or it
can change the way your vehicle
handles. This could result in loss of
control and cause personal injury.cOverloading can shorten the life of
the vehicle. Failures caused by over-
loading are not covered by the vehi-
cle's warranty.

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and
trailer. A genuine NISSAN trailer hitch is
available from your NISSAN dealer
(Canada only). Make sure the trailer hitch is
securely attached to the vehicle, to help
avoid personal injury or property damage
due to sway caused by crosswinds, rough
road surfaces or passing trucks.
CAUTION
cDo not use axle-mounted hitches.
cThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.
cAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
cRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (affixed
to the driver's door, center pillar).cTrailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer and tire
manufacturer's specifications.
Safety chains
Always use suitable chains between your
vehicle and the trailer. Safety chains should
be crossed and should be attached to the
hitch, not to the vehicle bumper or axle. Be
sure to leave enough slack in the chains to
permit turning corners.
Trailer lights
Trailer lights should comply with federal
and/ or local regulations. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and that it is prop-
erly installed.
10-16Technical and consumer information
ZX

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 pos-
sible causes of either condition.
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 will be
somewhat different than under normal driv-
ing conditions.cAlways secure items in the trailer to
prevent load shift while driving.
cAvoid 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, and if your vehicle is
equipped with an automatic transmis-
sion, first block the wheels and apply the
parking brake, and then move the shift
lever into the P position. If you move the
shift lever to the P position before block-
ing the wheels and applying the parking
brake, transmission damage could occur.
cWhen going down a hill, shift into a lower
gear 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 airconditioner system is on, turn off the air
conditioner. Coolant heat can be addi-
tionally vented by opening the windows,
switching the fan control to high and
setting the temperature control to the
HOT position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for the first 500
miles (800 km).
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 will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be pre-
pared for possible changes in crosswinds
that could affect vehicle handling. If
swaying does occur, firmly grip the steer-
ing wheel, steer straight ahead, and im-
mediately (but gradually) reduce vehicle

Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the ``ready
condition'' for an Inspection/Maintenance
(I/M) test of the emission control system.
The vehicle is set to the ``ready condition''
when it is driven through certain driving
patterns. Usually, the ready condition can be
obtained by ordinary usage of the vehicle.
If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a ``not ready'' condition.
Before taking the I/M test, drive the vehicle
through the following pattern to set the ve-
hicle to the ready condition. If you cannot or
do not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.
WARNING
Always drive the vehicle in a safe and
prudent manner according to traffic
conditions and obey all traffic laws.
1. Start the engine when the engine coolant
temperature gauge needle points to C.
Allow the engine to idle until the gauge
needle points between the C and H (nor-
mal operating temperature).2. Accelerate the vehicle to 55 mph (88
km/h), then quickly release the accelera-
tor pedal completely and keep it released
for at least 6 seconds.
3. Quickly depress the accelerator pedal for
a moment, then drive the vehicle at a
speed of 53 to 60 mph (86 to 96 km/h) for
at least 5 minutes.
4. Stop the vehicle.
5. Accelerate the vehicle to 35 mph (55
km/h) and maintain the speed for 20
seconds.
6. Repeat steps four through five at least
three times.
7. Accelerate the vehicle to 55 mph (88
km/h) and maintain the speed for at least
3 minutes.
8. Stop the vehicle (shift lever in the ``P'' or
``N'' position).
9. Rev the engine up between 2,500 and
3,500 rpm and hold it for 3 consecutive
minutes, then release the accelerator
pedal completely.
10. Wait 5 seconds at idle.
11. Rev the engine up between 2,000 and3,000 rpm and maintain it for 5 consecu-
tive minutes.
12. Stop the vehicle and turn the engine off.
13. Repeat steps one through twelve at
least one more time.
If step one through seven is interrupted,
repeat the preceding step. Any safe driving
mode is acceptable between steps. Do not
stop the engine until step seven is com-
pleted.
