2004 NISSAN FRONTIER check engine

Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
JUMP STARTING
If jump starting is necessary, see “Jump starting”
in the “In case of emergency” section of this
manual. If the engine does not start by jump
starting, the battery may have to be replaced.
Contact a NISSAN dealer.

WARNING
Be sure the ignition key is in the OFF or
LOCK position. The engine could rotate
unexpectedly.1. Visually inspect each belt for signs of un-
usual wear, cuts, fraying or looseness. If the
belt is in poor condition or is loose, have it
replaced or adjusted by a NISSAN dealer.
2. Have the belts checked regularly for condi-
tion and tension in accordance with the
maintenance schedule found in the
“NISSAN Service and Maintenance Guide”.

REPLACING SPARK PLUGS
Platinum-tipped spark plugs
It is not necessary to replace platinum-tipped
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance schedule, but do not reuse
the spark plugs by cleaning or regapping.
cAlways replace spark plugs with rec-
ommended or equivalent ones.

If you wax the surface of the hood, be careful not
to let wax get into the washer nozzle
s1. This may
cause clogging or improper windshield washer
operation. If wax gets into the nozzle, remove it
with a needle or small pin
s2.
CHECKING PARKING BRAKE
From the released position, firmly push the park-
ing brake down. If the number of clicks is out of
the range listed, see a NISSAN dealer.

between the upper surface of the pedal and the
metal floor. If it is out of the range shown, see a
NISSAN dealer.

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 vehicles self-adjust
every time the parking brake is applied. The rear
drum-type brakes on four-wheel drive vehicles
self-adjust every time the brake pedal is applied.
If the brake pedal goes down farther than normal,
it may be due to lack of adjustment of the rear
drum brakes. Apply the parking brake several
times.
WARNING
If the brake pedal height does not return
to normal, see a 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 re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal 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 a NISSAN dealer.
Proper brake inspection intervals should
be followed.For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
BRAKE BOOSTER
Check the brake booster function as follows:
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 the 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. Keep the pedal depressed for about
30 seconds. The pedal height should not
change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.

5. Press thebutton, then thebutton two or three times to check the key-
fob operation.
If the battery is removed for any reason
other than replacement, perform step 5.
cAn improperly disposed battery can
hurt the environment. Always confirm
local regulations for battery disposal.
cThe keyfob is water-resistant; how-
ever, if it does get wet, immediately
wipe completely dry.
cThe operational range of the keyfob
extends to approximately 33 ft (10 m)
from the vehicle. This range may vary
with conditions.
FCC Notice:
Changes or modifications not expressly ap-
proved by the manufacturer for compliance
could void the user’s authority to operate
the equipment.
This device complies with Part 15 of the FCC
Rules and RSS-210 of Industry Canada.
Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) this device
must accept any interference received, in-
cluding interference that may cause undes-
ired operation of the device.
HEADLIGHTS
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. A
bulb can be replaced from inside the engine
compartment without removing the headlight as-
sembly.
CAUTION
cHigh pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
cWhen handling the bulb, do not touch
the glass envelope.
cDO NOT TOUCH THE BULB
cUse the same number and wattage as
originally installed:
Wattage 65/55Bulb No. HB5/9007*
*: Always check with the Parts Depart-
ment at a NISSAN dealer for the latest
parts information.
cDo not leave the bulb out of the head-
light reflector for a long period of time
as dust, moisture and smoke may enter
the headlight body and affect the per-
formance of the headlight.cAiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, contact a NISSAN dealer.

Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum, varnish
or deposit removal may contain active solvents or
similar ingredients that can be harmful to the fuel
system and engine.
Octane rating tips
In most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 87 (except supercharger) or 91 (super-
charger ) AKI (Anti-Knock Index) . However, you
may use unleaded gasoline with an octane rating
as low as 85 AKI (Anti-Knock Index) number in
high altitude areas [over 4,000 ft (1,219 m)] such
as: Colorado, Montana, New Mexico, Utah, Wyo-
ming, northeastern Nevada, southern Idaho,
western South Dakota, western Nebraska, and
the 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.” (“Sparkknock” is a metallic rapping noise.) If se-
vere, 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 a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
