manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front of
you. Ultimately, the driver is respon-
sible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h). The speed varies according to road
conditions.

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 defroster Check that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery (for serviceable battery)* Check the
fluid level in each cell. It should be between the
MAX and MIN lines. Vehicles operated in high
temperatures or under severe conditions require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc.) 2. Vehicle is not driven regularly and/or only
driven short distances. In these cases, the
battery may need to be charged to maintain
battery health.
Brake and clutch (if so equipped) fluid lev-
els* Make sure that the brake and clutch fluid
level is between the MIN and MAX lines on the
reservoir.
Engine coolant level* Check the coolant level
when the engine is cold.
Engine drive belts* Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level* Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust system Make 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 a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaks Check 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 imme-
diately.
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.
Radiator and hoses Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances 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 thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield-washer fluid* Check that there is
adequate fluid in the reservoir.

CHANGING ENGINE OIL FILTER
1. Park the vehicle on a level surface and applythe parking brake.
2. Turn the engine off.
3. Place a large drain pan under the oil filter.
4. Unscrew the plate covering the oil filter ex- posing the filter.
5. Loosen the oil filter
Awith an oil filter
wrench by turning it counterclockwise. Then
remove the oil filter by turning it by hand.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot.
6. Wipe the engine oil filter sealing surface with a clean rag.
CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the
engine. Failure to do so could lead to
engine damage.
7. Coat the gasket on the new filter with clean engine oil.
8. Screw on the oil filter until a slight resistance is felt, then tighten an additional 2/3 turn.
9. Start the engine and check for leakage around the oil filter. Correct as required.
10. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine
oil if necessary. When checking or replacement is required, we
recommend your NISSAN dealer for servicing.
CAUTION
●
Use Genuine NISSAN Matic S ATF. If
Genuine NISSAN Matic S ATF is not
available, Genuine NISSAN Matic J ATF
may also be used.
● Using automatic transmission fluid
other than Genuine NISSAN Matic S
ATF or Matic J ATF will cause deteriora-
tion in driveability and automatic trans-
mission durability, and may damage the
automatic transmission, which is not
covered by the NISSAN new vehicle lim-
ited warranty.
The specified automatic transmission fluid is also
described on caution labels located in the engine
compartment.

Maintenance and do-it-yourself8-11

CLUTCH FLUID (if so equipped)
Check the clutch fluid level in the reservoir
(manual transmissions only) . If the fluid level is
below the MIN line, add Genuine NISSAN Super
Heavy Duty Brake Fluid or equivalentDOT 3fluid
up to the MAX line. If fluid must be added fre-
quently, the system should be checked by a
NISSAN dealer.
For further brake and clutch fluid specification
information, refer to “Capacities and recom-
mended fuel/lubricants” in the “Technical and
consumer information” section of this manual.
WINDSHIELD-WASHER FLUID
RESERVOIR
Fill the windshield-washer fluid reservoir periodi-
cally. Add windshield-washer fluid when the low
windshield-washer fluid warning light (if so
equipped) comes on.
To fill the windshield-washer fluid reservoir, lift
the cap off the reservoir and pour the windshield-
washer fluid into the reservoir opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s in-
structions for the mixture ratio. Refill the reservoir more frequently when driving
conditions require an increased amount of
windshield-washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
●
Do not substitute engine anti-freeze
coolant for windshield-washer solution.
This may result in damage to the paint.
● Do not fill the windshield-washer reser-
voir with washer fluid concentrates at
full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the windshield-washer
reservoir.
● Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the windshield-washer reservoir.
Do not use the windshield-washer res-
ervoir to mix the washer fluid concen-
trate and water.

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.

●If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol) . It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not avail-
able to ensure that all methanol blends
are suitable for use in NISSAN ve-
hicles.
If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
E–15 fuel
E-15 fuel is a mixture of approximately 15% fuel
ethanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed to run on E-15
fuel. Do not use E-15 in your vehicle. U.S. gov-
ernment regulations require fuel ethanol dispens-
ing pumps to be identified with small, square, orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
E–85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
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
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If youdetect 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.
