2003 NISSAN XTERRA engine

Your new vehicle was designed to be used pri-
marily to carry passengers and cargo. Remember
that towing a trailer places additional loads on
your vehicle’s engine, drive train, steering, brak-
ing and other systems.
ANissan Trailer Towing Guide (U.S. only)is
available from a NISSAN dealer. This guide in-
cludes 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 found later in this sec-
tion.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 sys-
tem 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 greaterthan 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 appro-
priate for level highway driving may have to be
reduced on very steep grades or in low traction
situations (for example, on slippery boat ramps) .
WARNING
Vehicle damage and/or personal injury re-
sulting from improper towing procedures
are not covered by NISSAN warranties. A
NISSAN Trailer Towing Guide (U.S. only)
containing information on trailer towing
ability and the special equipment required
may be obtained from a NISSAN dealer.
Tongue load
Keep the tongue load between9-11percent of
the total trailer load within the maximum tongue
load limits shown in the following Towing
Load/Specification Chart. If the tongue load be-
comes excessive, rearrange cargo to allow for
proper tongue load.

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.

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 recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
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 adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help sta-
bilize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.cTo maintain engine braking efficiency and
electrical charging performance, do not use
5th gear (manual transmission) or overdrive
(automatic transmission) .
cAvoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
When towing a trailer, transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.DOT (Department of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
Treadwear
Treadwear grade is a comparative rating based
on tire wear rate when tested under controlled
conditions on specified government test courses.
For example, a tire graded 150 would wear one
and a half (1-1/2) times as well on the govern-
ment course as a tire graded 100. However,
relative tire performance depends on actual driv-
ing conditions, and may vary significantly due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.

If you believe that your vehicle has a defect which
could cause a crash or could cause injury or
death, you should immediately inform the Na-
tional Highway Traffic Safety Administration
(NHTSA) in addition to notifying NISSAN.
If NHTSA receives similar complaints, it may
open an investigation, and if it finds that a safety
defect exists in a group of vehicles, it may order a
recall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or NISSAN.
To contact NHTSA, you may call the Auto Safety
Hotline toll-free at 1-888-327-4236. You may
also write to: NHTSA, U.S. Department of Trans-
portation, Washington, D.C. 20590. You can also
obtain other information about motor vehicle
safety from the Hotline.
You may notify NISSAN by contacting our Con-
sumer Affairs Department, toll-free, at 1-800-
NISSAN-1.
In Hawaii call 1-808-836-0888.Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” 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 vehicle 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 con-
ditions and obey all traffic laws.
1. Start the engine when the engine coolant
temperature gauge needle points to C. Al-
low the engine to idle until the gauge needle
points between the C and H (normal oper-
ating temperature) .2. Accelerate the vehicle to 55 mph (88 km/h) ,
then quickly release the accelerator 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 - 60 mph (85 - 97 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 4 through 5 at least three
times.
7. Accelerate the vehicle to 55 mph (88 km/h)
and maintain the speed for at least 3 min-
utes.
8. Stop the vehicle and turn the engine off.
9. Repeat steps 1 through 8 at least one more
time.
If steps 1 through 7 are interrupted, repeat the
preceding step. Any safe driving mode is accept-
able between steps. Do not stop the engine until
step 7 is completed. If you cannot or do not want
to perform the driving pattern, a NISSAN dealer
can conduct it for you.
