2003 NISSAN XTERRA ECU

3. Route the trailer tow harness so that it does
not block access to the spare tire winch
socket.
4. Connect the tow harness connector (SAE
J1239) to your trailer.
5. Confirm proper vehicle and trailer stop/turn
lamp operation.
6.
When towing is completed, disconnect the
tow harness from the trailer and the vehicle.
Store the tow harness in the glove box. Rein-
stall the connector cap to the vehicle harness.
If you need further assistance in wiring a trailer to
your NISSAN, contact a NISSAN dealer.
Always confirm proper vehicle and trailer
stop/turn lamp operation every time the
trailer light circuits are connected for use.
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 properly installed.
WARNING
Never connect a trailer brake system di-
rectly 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 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 practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving 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.
c
Always 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 transmission, first block the
wheels and apply the parking brake, and
then move the transmission shift selector
lever into the P (Park) position. If you move
the shift selector lever to the P (Park) posi-
tion 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 going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading 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 extremely
high temperature when the air conditioner
system is on, turn off the air conditioner.
Coolant heat can be additionally 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.
