2004 NISSAN XTERRA wiring

cNo unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This is
to prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the supplemental front air bag system.
cTampering with the supplemental front
air bag system may result in serious
personal injury. Tampering includes
changes to the steering wheel and the
instrument panel assembly by placing
material over the steering wheel pad
and above the instrument panel or by
installing additional trim material
around the air bag system.cWork on and around the supplemental
front air bag system should be done by
a NISSAN dealer. Installation of electri-
cal equipment should also be done by a
NISSAN dealer. The Supplemental Re-
straint System (SRS) wiring should not
be modified or disconnected. Unautho-
rized electrical test equipment and
probing devices should not be used on
the air bag system.
cA cracked windshield should be re-
placed immediately by a qualified re-
pair facility. A cracked windshield could
affect inflation of the supplemental air
bag system.
cThe SRS wiring harness connectors are
yellow and orange for easy
identification.
When selling your vehicle, we request that you
inform the buyer about the supplemental front air
bag system and guide the buyer to the appropri-
ate sections in this Owner’s Manual.
Supplemental curtain side-impact air
bag system (if so equipped)
The supplemental curtain side-impact air bags
are located in the roof side rails. This system is
designed to meet voluntary guidelines to help
reduce the risk of injury to out-of-position occu-
pants.However, all of the information, cau-
tions and warnings in this manual still ap-
ply and must be followed.The curtain side-
impact air bags are designed to inflate in higher
severity side collisions, although they may inflate
if the forces in another type of collision are similar
to those of a higher severity side impact. They are

designed to inflate on the side where the vehicle
is impacted. They may not inflate in certain side
collisions.
Vehicle damage (or lack of it) is not always an
indication of proper supplemental curtain side-
impact air bag operation.
When the supplemental curtain side-impact air
bags inflate, a fairly loud noise may be heard,
followed by release of smoke. This smoke is not
harmful and does not indicate a fire. Care should
be taken not to inhale it, as it may cause irritation
and choking. Those with a history of a breathing
condition should get fresh air promptly.
Supplemental curtain side-impact air bags help
to cushion the impact force to the head of occu-
pants in the front and rear outboard seating po-
sitions. They can help save lives and reduce
serious injuries. However, an inflating curtain
side-impact air bag may cause abrasions or other
injuries. Supplemental curtain side-impact air
bags do not provide restraint to the lower body.
Rear seat passengers should be seated as far
away as practical from the door finishers and side
roof rails. The curtain side-impact air bag inflate
quickly in order to help protect the occupants.
Because of this, the force of the curtain side-
impact air bag inflating can increase the risk of
injury if the occupant is too close to, or is against,these air bag modules during inflation. The cur-
tain side-impact air bag will deflate quickly after
the collision is over.
The supplemental curtain side-impact air
bags operate only when the ignition switch
is in the ON or START position.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.
WARNING
cRight after inflation, several curtain
side-impact air bag system compo-
nents will be hot. Do not touch them;
you may severely burn yourself.
cNo unauthorized changes should be
made to any components or wiring of
the curtain side-impact air bag system.
This is to prevent accidental inflation of
the curtain side-impact air bag or dam-
age to the curtain side-impact air bag
system.cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or side panel. This
could affect proper operation of the
supplemental curtain side-impact air
bag system.
cWork around and on the curtain side-
impact air bag system should be done
by a NISSAN dealer. Installation of elec-
trical equipment should also be done by
a NISSAN dealer. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical test
equipment and probing devices should
not be used on the side air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the supplemental side air
bag and curtain side-impact air bag system and
guide the buyer to the appropriate sections in this
Owner’s Manual.

Pre-tensioner seat belt system (for
front seats)
WARNING
cThe pre-tensioner seat belt cannot be
reused after activation. It must be re-
placed together with the retractor and
buckle as a unit.
cIf the vehicle becomes involved in a
frontal collision but the pre-tensioner is
not activated, be sure to have the pre-
tensioner system checked and, if nec-
essary, replaced by your NISSAN
dealer.
cNo unauthorized changes should be
made to any components or wiring of
the pre-tensioner seat belt system. This
is to prevent accidental activation of
the pre-tensioner seat belt or damage
to the pre-tensioner seat belt operation.
Tampering with the pre-tensioner seat
belt system may result in serious per-
sonal injury.cWork around and on the pre-tensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pre-tensioner seat
belt system.
cIf you need to dispose of the pre-
tensioner or scrap the vehicle, contact a
NISSAN dealer. Correct pre-tensioner
disposal procedures are set forth in the
appropriate NISSAN Service Manual.
Incorrect disposal procedures could
cause personal injury.
The front seat pre-tensioner seat belt system
activates in conjunction with the supplemental air
bag systems. Working with the seat belt retrac-
tor, it helps tighten the seat belt when the vehicle
becomes involved in certain types of collisions,
helping to restrain front seat occupants.
The pre-tensioner is encased with the seat belt’s
retractor. These seat belts are used the same as
conventional seat belts.
When the pre-tensioner seat belt activates,
smoke is released and a loud noise may be heard.
This smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it maycause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
If any abnormality occurs in the pre-tensioner
system, the supplemental air bag warning
lightwill flash intermittently after the igni-
tion key is turned to the ON or START position. In
this case, the pre-tensioner seat belt will not
function properly. They must be checked and
repaired. Take your vehicle to the nearest
NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pre-tensioner seat belt
system and guide the buyer to the appropriate
sections in this Owner’s Manual.

WARNING
cOn hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or possi-
bly fatal injuries to people or animals.
Do not leave children or adults who
would normally require the support of
others in your vehicle. Unattended pets
should not be left alone either.
cProperly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
cDo not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death.
cIf you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.cDo not run the engine in closed spaces
such as a garage.
cDo not park the vehicle with the engine
running for any extended length of time.
cKeep the back door and rear windows
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
the back door or rear windows open,
follow these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton (if so equipped) to off and the fan
control dial to 4 (high) to circulate
the air.
cIf electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the back door or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle.
cThe exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of
the exhaust system.
d. You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
cThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
cDo not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.

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.
Reinstall 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 rearview 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.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 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.
