Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck 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*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.UnderbodyThe 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
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the selector
lever to P (Park).
cBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
cNever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
cNever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight shifts
that could affect the balance of your vehicle.
When the truck camper is loaded, drive to a
scale and weigh the front and the rear
wheels separately to determine axle loads.
Individual axle loads should not exceed
either of the gross axle weight ratings
(GAWR). The total of the axle loads should
not exceed the gross vehicle weight rating
(GVWR). These ratings are given on the
vehicle certification label that is located on
the driver's door lock pillar. If weight ratings
are exceeded, move or remove items to
bring all weights below the ratings.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer will place
additional loads on your vehicle's engine,
drive train, steering, braking and other sys-
tems.
ANissan Trailer Towing Guideis avail-
able from an authorized NISSAN dealer.
This guide includes information on trailer
towing ability and the special equipment
required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed
the value specified in the following Towing
Load/Specification Chart. The total trailer
load equals trailer weight plus its cargo
weight.
cWhen towing a trailer load of 1,000 lbs.
(454 kg) or more, trailers with a brake
system MUST be used.
The maximum GCWR (Gross Combined
Weight Rating) should not exceed the value
specified in the following Towing Load/
Specification Chart.
The GCWR equals the combined weight of
the towing vehicle (including passengers
and cargo) plus the total trailer load. Towing
loads greater than these or using improper
towing equipment could adversely affect
vehicle handling, braking and performance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer
loads, but also the places you plan to tow.
Tow weights appropriate for level highway
driving may have to be reduced on very

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 con-
dition.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your outside mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for tow-
ing 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.
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, and if your vehicle is
equipped with automatic transmission,
first block the wheels and apply the
parking brake, and then move the trans-
mission shift selector lever into the P
(Park) position. If you move the shift
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 lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
However, for long steep grades, do not
stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h).
cIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning 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 your vehicle's
first 500 miles (805 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 compen-
sate for this, make a larger than normal
turning radius during the turn.
cCrosswinds and rough roads adversely
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 imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
