1997 NISSAN FRONTIER light

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 your NISSAN 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 your NISSAN
dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.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 pedal
application 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 your NISSAN dealer.

cImproper service for a TEMPORARY
USE ONLY spare tire may result in
serious personal injury. If it is nec-
essary to repair the TEMPORARY
USE ONLY spare tire, contact your
NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. Recommended types
and sizes are shown in ``Wheel/tire size'' in
the ``Technical and consumer information''
section.
WARNING
c
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, snow chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.cIf 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 early tire wear, poor ve-
hicle handling characteristics and/or
interference with the brake discs/
drums. Such interference can lead to
decreased braking efficiency and/or
early brake pad/shoe wear.
cDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
4-WHEEL DRIVE MODELS
CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked
and corrected as necessary. Contact your
NISSAN dealer.
CAUTION
ONLY use spare tires specified for each
4-wheel drive model.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the front wheels on the vehicle could
lead to transmission damage.
Care of wheels
cWash the wheels when washing the ve-
hicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.

make sure no nuts are missing, and check
for any loose nuts. Tighten if necessary.
Tire rotation*Tires should be rotated every
7,500 miles (12,000 km) for 2WD vehicles
and 3,750 miles (6,000 km) for 4WD ve-
hicles.
Wheel alignment and balanceIf the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may be
a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades*Check for
cracks or wear if they do not wipe properly.
Doors and engine hoodCheck that all
doors and the engine hood operate prop-
erly. Also ensure that all latches lock se-
curely. Lubricate hinges, latches, rollers and
links if necessary. Make sure that the sec-
ondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.Lights*Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
INSIDE THE VEHICLE
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Warning lights and chimesMake sure all
warning lights and chimes are operating
properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and
that the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheelCheck for changes in the
steering conditions, such as excessive free-
play, hard steering or strange noises.SeatsCheck seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints move up and
down smoothly and the locks (if so
equipped) hold securely in all latched posi-
tions.
Seat beltsCheck that all parts of the seat
belt system (e.g., buckles, anchors, adjust-
ers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedalCheck the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mats away from the pedal.
Clutch pedal*Make sure the pedal oper-
ates smoothly and check that it has the
proper free travel.
BrakesCheck that the brakes do not pull
the vehicle to one side when applied.
Brake pedal and booster*Check the pedal
for smooth operation and make sure it has
the proper distance under it when de-
pressed fully. Check the brake booster func-

Octane rating tips
In most parts of North America, you should
use unleaded gasoline with an octane rating
of at least 87 AKI (Anti-Knock Index). How-
ever, you may use unleaded gasoline with
an octane rating as low as 85 AKI in high
altitude areas (over 4,000 ft [1,219 m]) such
as: Colorado, Montana, New Mexico, Utah,
Wyoming, northeastern Nevada, southern
Idaho, western South Dakota, western Ne-
braska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady speed
on level roads, have your dealer correct
the condition. Failure to correct the con-
dition is misuse of the vehicle, for which
NISSAN is not responsible.
Incorrect ignition timing results in knocking,
after-run and/or overheating. This in turn
may cause excessive fuel consumption ordamage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked at a NISSAN dealer or other
competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.

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. Make sure the trailer hitch is securely
attached to the vehicle to help avoid per-
sonal 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 are available at your NISSAN
dealer.
cDo not use axle-mounted hitches.
cDo not modify the vehicle exhaust
system, brake system, etc. when the
hitch is installed.
cTo reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch when not in use.
Remove receiver when not in use.After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
cCheck regularly to make sure that all
trailer hitch mounting bolts are se-
curely fastened.Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (affixed
to 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 a suitable chain between your
vehicle and the trailer. The chain 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 your 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 condi-
tion.
cAlways secure items in the trailer to
