2001 NISSAN FRONTIER manual transmission

cImproper 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.
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
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, tire 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 pre-mature tire wear, de-
grade vehicle handling characteris-
tics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. Refer to(Wheel/tire size(in the
(Technical and consumer informa-
tion(section of this manual for wheel
off-set dimensions.
cDo 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.
cThe use of retread tires is not recom-
mended.
Four-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 an
authorized NISSAN dealer.
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.

for smooth operation and make sure it has
the proper distance under it when de-
pressed fully. Check the brake booster func-
tion. Be certain to keep the floor mat away
from the pedal.
Parking brake*Check that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill
with only the parking brake applied.
Automatic transmission P (Park) posi-
tion mechanismCheck that the lock re-
lease button on the selector lever operates
properly and smoothly. On a fairly steep hill
check that your vehicle is held securely with
the selector lever in the P position without
applying any brakes.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (e.g., each time you
check the engine oil or refuel).
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself operations'' section.
Windshield washer fluid*Check that there
is adequate fluid in the reservoir.
Engine oil level*Check the level afterparking the vehicle on a level surface with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Brake and clutch fluid levels*Make sure
that the brake and clutch fluid level is be-
tween the MIN and MAX lines on the reser-
voir.
Power steering fluid level* and lines
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Engine coolant level*Check the coolant
level when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.
UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
