2002 NISSAN FRONTIER ECU

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

TOWING A TRAILER
Technical and consumer information9-21

TOWING SAFETY
Trailer hitch
Check the towing capacity of your bumper
hitch or receiver-type frame mounted hitch.
Choose a proper hitch for your vehicle and
trailer. A genuine Nissan trailer hitch is
available from your NISSAN dealer. 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
cSpecial hitches which include frame
reinforcements are required for tow-
ing above 2,000 lb (907 kg). Suitable
genuine NISSAN hitches for pickup
trucks and sport utility vehicles are
available at an authorized NISSAN
dealer.
cThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
cDo not use axle-mounted hitches.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. Remove receiver
when not in use. After the hitch is
removed, seal the bolt holes to pre-
vent exhaust fumes, water or dust
from entering the passenger com-
partment.
cRegularly check that all trailer hitch
mounting 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 (af-
fixed to the inside of the glove box lid).
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' specifications.
Safety chain
Always use suitable safety 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
chain to permit turning corners.
Trailer lights
Trailer lights should comply with Federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an autho-
rized NISSAN dealer.
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.
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 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.
