2002 NISSAN XTERRA brake

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front disc-type brakes self-adjust every
time the brake pedal is applied. The rear
drum-type brakes on two-wheel drive trucks
self-adjust every time the parking brake is
applied. The rear drum-type brakes on four-
wheel drive trucks self-adjust every time the
brake pedal is applied. If the brake pedal
goes down farther than normal, it may be
due to a lack of adjustment of the rear drum
brakes. Apply the parking brake several
times.
WARNING
If the brake pedal height does not re-
turn to normal, see an authorized NIS-
SAN dealer and have it checked.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakeschecked as soon as possible if the wear
indicator sound is heard.
Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is nor-
mal and does not affect the function or
performance of the brake system.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise from
the rear drum brakes, have them inspected
as soon as possible by an authorized NIS-
SAN dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``NISSAN Service and Maintenance Guide.''
BRAKE BOOSTER
Check the brake booster function with the
following steps:
1. With the engine off, press and release
the brake pedal several times. When
brake pedal movement (distance of
travel) remains the same from one pedalapplication to the next, continue on to
next step.
2. While depressing the brake pedal, start
the engine. The pedal height should drop
a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height
should not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it
off. Depress the brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression
as the vacuum is released from the
booster.
If the brakes do not operate properly, have
the brakes checked by an authorized
NISSAN dealer.

Tire wear and damage
WARNING
OTires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If
excessive wear, cracks, bulging or
deep cuts are found, the tire(s)
should be replaced.
OThe original tires have a built-in
tread wear indicator. When the wear
indicators are visible, the tire(s)
should be replaced.OImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an authorized
NISSAN dealer.
OFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance information
booklet (Canada).
Replacing tires and wheels
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. Recom-
mended types and sizes are shown in
``Wheel/tire size'' in the ``Technical and con-
sumer information'' section of this manual.
WARNING
O
The use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,braking, handling, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
OIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause premature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interfer-
ence can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. Refer to ªWheel/tire
sizeº in the ªTechnical and con-
sumer informationº section of this
manual for wheel off-set dimen-
sions.
ODo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have unknown
structural damage and could fail
without warning.

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight shifts
that could affect the balance of your vehicle.
When the vehicle is loaded, drive to a scale
and weigh the front and the rear wheels
separately to determine axle loads. Indi-
vidual axle loads should not exceed either
of the gross axle weight ratings (GAWR).
The total of the axle loads should not ex-
ceed 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 Guide (U.S. only)
is available from an authorized NISSAN
dealer. This guide includes information on
trailer towing ability and the special equip-
ment 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.
OWhen 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
steep grades or in low traction situations (for
example, on slippery boat ramps).

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 avail-
able 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
OSpecial 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.
OThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
ODo not use axle-mounted hitches.ODo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
OTo 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.
OAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
ORegularly check that all trailer hitch
mounting bolts are securely
mounted.
Tire pressures
OWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (affixed
to the inside of the glove box lid).
OTrailer 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.

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 an autho-
rized NISSAN dealer.
Always confirm proper vehicle and
trailer stop/turn lamp operation every
time the trailer light circuits are con-
nected 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 prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
OBe 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 condi-
tion.
OAlways secure items in the trailer to
prevent load shift while driving.
OBe certain your outside 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 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.
OAlways secure items in the trailer to
prevent load shift while driving.
O
Avoid abrupt starts, acceleration or stops.
OAvoid sharp turns or lane changes.
OAlways drive your vehicle at a moderate
speed.
OAlways 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 park-
ing brake, and then move the transmis-
sion 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.
OWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine 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).
OIf 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.
OTrailer towing requires more fuel than
normal circumstances.
OAvoid towing a trailer for your vehicle's
first 500 miles (805 km).
OHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
OWhen 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.
OCrosswinds 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 immedi-
ately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.OBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
OTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
OAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change oil in the
transmission more frequently. For addi-
tional information see the ``Maintenance
and do-it-yourself'' section earlier in this
manual.DOT (Department of Transportation) Quality
Grades: All passenger car tires must con-
form to Federal Safety Requirements in
addition to these grades.
Quality grades can be found where appli-
cable 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 govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However, rela-
tive tire performance depends on actual
driving conditions, and may vary signifi-
cantly 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 repre-
sent the tire's ability to stop on wet pave-
