CAUTION
●Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator. The current sensor
Ais located near the battery
along the negative battery cable. If you add elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as
the frame or engine block area.
1. Power steering fluid pump
2. Automatic belt tensioner
3. Cooling fan
4. Air conditioner compressor
5. Crankshaft pulley
6. Generator
WARNING
Be sure the ignition key is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.

8-16Maintenance and do-it-yourself

1. Visually inspect the belt for signs of unusualwear, 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 belt 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-tippedA
spark plugs as frequently as conventional type
spark plugs because they last much longer. Fol-
low the maintenance log shown in the “NISSAN
Service and Maintenance Guide”. Do not service
platinum-tipped spark plugs by cleaning or re-
gapping.
● Always replace spark plugs with rec-
ommended or equivalent ones.
WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect socket
can damage the spark plugs.

The air cleaner filter should not be cleaned and
reused. Replace it according to the maintenance
log shown in the “NISSAN Service and Mainte-
nance Guide.”
To remove the air cleaner filter:
1Unlatch the clips and move the air cleaner
cover upward.
2. Remove the air cleaner filter.
3. Wipe the inside of the air cleaner filter hous- ing and the cover with a damp cloth. NOTE:
After installing a new air cleaner, make
sure the air cleaner cover is seated in the
housing and latch the clips.
WARNING
●Operating the engine with the air cleaner
removed can cause you or others to be
burned. The air cleaner not only cleans
the air, it stops the flame if the engine
backfires. If it isn’t there, and the engine
backfires, you could be burned. Do not
drive with the air cleaner removed, and
be careful when working on the engine
with the air cleaner removed.
● Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
IN-CABIN MICROFILTER (if so
equipped)
The in-cabin microfilter restricts the entry of air-
borne dust and pollen particles and reduces some
objectionable outside odors. The filter is located
behind the glove box. Refer to the “NISSAN Ser-
vice and Maintenance Guide” for change intervals.
To replace the filter, perform the following proce-
dure: 1. Open the glove box and press in on the
sides so that it will open completely allowing
it to hang by the cord.

If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
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.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”.
Two types of fuses are used. Type
Ais used in
the fuse boxes in the engine compartment. Type
Bis used in the passenger compartment fuse
box.
Type A fuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type A fuses can be installed in the engine com-
partment and passenger compartment fuse
boxes.

BRAKES FUSES
8-22Maintenance and do-it-yourself

If a type A fuse is used to replace a type B fuse,
the type A fuse will not be level with the fuse
pocket as shown in the illustration. This will not
affect the performance of the fuse. Make sure the
fuse is installed in the fuse box securely.
Type B fuses cannot be installed in the under-
hood fuse boxes. Only use type A fuses in the
underhood fuse boxes.ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not come on,
check for an open fuse. 1. Be sure the ignition switch and the headlight switch are OFF.
2. Open the engine hood. 3. Remove the fuse box cover by pushing the
tab and lifting the cover up.
4. Remove the fuse with the fuse puller. The fuse puller is located in the center of the fuse
block in the passenger compartment.

tery is incorrectly replaced. Replace only
with the same or equivalent type.
Recommended battery: CR2025 or equivalent.
4Close the lid securely.
5. Press the
button, 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. ● An improperly disposed battery can
hurt the environment. Always confirm
local regulations for battery disposal.
● The keyfob is water-resistant; how-
ever, if it does get wet, immediately
wipe completely dry.
● The operational range of the keyfob
extends to approximately 33 ft (10 m)
from the vehicle. This range may vary
with conditions. For USA:
This device complies with Part 15 of the
FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) This device may
not cause harmful interference, and (2) this
device must accept any interference re-
ceived, including interference that may
cause undesired operation. Note: Changes
or modifications not expressly approved by

void the user’s authority to operate the
equipment.
For Canada:
This device complies with RSS-210 of In-
dustry Canada. Operation is subject to the
following two conditions: (1) this device
may not cause interference, and (2) this
device must accept any interference, in-
cluding interference that may cause unde-
sired 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
●
High pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
● When handling the bulb, do not touch
the glass envelope.
● DO NOT TOUCH THE BULB WITH BARE
HANDS.
● Use the same number and wattage as
shown in the chart.
● Do 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.
● Aiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, contact a NISSAN dealer.
