1997 NISSAN FRONTIER suspension

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 dam-
age to the supplemental air bag
system.
cDo not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the supplemental air
bag system.
cTampering with the supplemental air
bag system may result in serious
personal injury. Tampering includes
changes to the steering wheel by
placing material over the steering
wheel pad or by installing additional
trim material around the supplemen-
tal air bag system.cWork around and on the supplemen-
tal air bag system should be done by
an authorized NISSAN dealer. Instal-
lation of electrical equipment should
also be done by an authorized NIS-
SAN dealer. The yellow SRS wiring
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the supple-
mental air bag system.
cSRS wiring harnesses are covered
with yellow insulation either just be-
fore the harness connectors or over
the complete harness for easy iden-
tification.
When selling your vehicle, we request that
you inform the buyer about the supplemen-
tal air bag system and guide the buyer to the
appropriate sections in this Owner's
Manual.

VEHICLE RECOVERY (freeing a
stuck vehicle)
cTow chains or cables must be attached
only to the main structural members of
the vehicle.
cPulling devices should be routed so they
do not touch any part of the suspension,
steering, brake or cooling systems.
cAlways pull the cable straight out from
the front or rear of the vehicle. Never pull
on the vehicle at an angle.
cPulling devices such as ropes or canvas
straps are not recommended for use in
vehicle towing or recovery.
cStand clear of a stuck vehicle.
WARNING
Do not spin your tires at high speed.
This could cause them to explode and
result in serious injury. Parts of your
vehicle could also overheat and be
damaged.

choosing the proper product.
cWax your vehicle only after a thorough
washing. Follow the instructions supplied
with the wax.
cDo not use a wax containing any abra-
sives, cutting compounds or cleaners
that may damage the vehicle finish.
cIf the surface does not polish easily, use
a ``road tar'' remover and wax again.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint finish
may dull the finish or leave swirl marks.
Only apply black wax or black shoe polish to
the black urethane or polypropylene
bumper.
Removing spots
Remove tar and oil spots, industrial dust,
insects and tree sap as quickly as possible
from the surface of the paint to avoid per-
manent damage or staining. Special clean-
ing products are available at your NISSAN
dealer or any automotive accessories store.
Underbody
In areas where road salt is used in winter, it
is necessary to clean the underbody regu-larly in order to prevent dirt and salt from
building up and causing corrosion on the
underbody and suspension. Before the win-
ter period and again in the spring, the
underseal must be checked and, if neces-
sary, retreated.
Cleaning glass
Use glass cleaner to remove smoke and
dust film from the glass surfaces. It is nor-
mal for glass to be coated with a film after
the vehicle is parked in the hot sun. Glass
cleaner and a soft cloth easily remove this
film.
CAUTION
When cleaning the inside of the win-
dow, do not use any sharp-edged tools
or abrasive cleaners or chlorine-based
disinfectant cleaners. They could dam-
age the electrical conductors, radio an-
tenna elements or rear window defog-
ger elements.
Cleaning aluminum alloy wheels
Wash regularly, especially during winter
months in areas where road salt is used.
Salt could discolor the wheel if not removed.
Chrome parts
Clean all chrome parts regularly with a
non-abrasive chrome polish to maintain the
finish.
Cleaning interior
Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or soft brush. Wipe the
vinyl and leather surfaces with a clean, soft
cloth dampened in mild soap solution, then
wipe clean with a dry soft cloth. Before
using any fabric protector, read the manu-
facturer's recommendations. Some fabric
protectors contain chemicals that stain or
bleach the seat material.
CAUTION
cNever use benzine, thinner or any
similar material.
cNever use fabric protectors unless
recommended by the manufacturer.

EXPLANATION OF
MAINTENANCE ITEMS
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Emission control system
maintenance
Drive belts*Check drive belts for wear,
fraying or cracking and also for proper ten-
sion. Replace the drive belts if found dam-
aged or in accordance with the mainte-
nance schedule.
Air cleaner filterUnder normal driving con-
ditions, the air cleaner filter should be re-
placed in accordance with the maintenance
schedule. However, driving the vehicle in
dusty areas may cause more rapid clogging
of the element. Consequently, the element
may have to be replaced more frequently.
Positive crankcase ventilation (PCV) fil-
terUnder normal driving conditions, the
filter should be replaced in accordance with
the maintenance schedule. If the vehicle is
operated under extremely adverse weather
conditions or in areas where ambient tem-
peratures are either extremely low or ex-tremely high, the filter may become clogged
more rapidly. In such an event, replace the
filter immediately.
Vapor linesCheck vapor lines and connec-
tions for failure or looseness. If leaks are
found, replace the lines.
Fuel lines (hoses, piping, connections,
etc.)Check the fuel hoses, piping and con-
nections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Fuel filterIf the vehicle is operated under
extremely adverse weather conditions or in
areas where ambient temperatures are ei-
ther extremely low or extremely high, the
filter might become clogged. In such an
event, replace the filter immediately.
Engine coolant*Flush and refill the cooling
system.
Engine oil and oil filter*Under normal
driving conditions, the engine oil and oil filter
should be replaced in accordance with the
maintenance schedule. However, under se-
vere driving conditions, they may have to be
replaced more frequently.
Spark plugs*Replace with new plugs hav-
ing the correct heat range.
Chassis and body maintenance
Brake lines and cablesCheck the brake
lines and hoses (including brake booster
vacuum hoses, connections & check valve)
and parking brake cables for proper attach-
ment, leaks, cracks, chafing, abrasion, de-
terioration, etc.
Brake pads, discs, drums and linings
Check these and the other neighboring
brake components for wear, deterioration
and leaks. Under severe driving conditions,
they may have to be inspected more fre-
quently.
Manual and automatic transmission,
transfer and differential gear oilVisually
inspect for signs of leakage and replace oil
for limited-slip differential. Under severe
driving conditions, the oil should be re-
placed at the specified interval.
Steering gear (box) and linkage, axle and
suspension parts and drive shaft boots
Check for damage, looseness and leakage
of oil or grease. Under severe driving con-
ditions, more frequent inspection should be
performed.

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
