Shifting
To change gears or when upshifting or down-
shifting, depress the clutch pedal fully, shift into
the appropriate gear, then release the clutch
slowly and smoothly.
To ensure smooth gear changes, fully depress
the clutch pedal before operating the shift selec-
tor. If the clutch pedal is not fully depressed
before the transmission is shifted, a gear noise
may be heard. Transmission damage may occur.
Start the vehicle in 1st gear and shift to 2nd, 3rd,
4th and 5th up to 6th gear in sequence according
to vehicle speed.To back up, lift up on the shift selector ring
1and
then move it to the R (Reverse) position after
stopping the vehicle completely.
The shift selector ring
1returns to its original
position when the shift selector is moved to the N
(Neutral) position.
If it is difficult to move the shift selector into R
(Reverse) or 1 (1st) , shift into N (Neutral) , then
release the clutch pedal. Depress the clutch
pedal again and shift into R (Reverse) or 1 (1st) .
Suggested up-shift speeds
The following are suggested vehicle speeds for
shifting into a higher gear. These suggestions
relate to fuel economy and vehicle performance.

CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
● Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
● Use a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
● Avoid unnecessary engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary. ●
When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● Use the recommended viscosity engine oil.
See “Capacities and recommended
fuel/lubricants” in the “Technical and con-
sumer information” section of this manual.

CAUTION
●NEVER remove dirt, sand or other de-
bris from the passenger compartment
by washing it out with a hose. Remove
dirt with a vacuum cleaner or broom.
● Never allow water or other liquids to
come in contact with electronic compo-
nents inside the vehicle as this may
damage them.
Chemicals used for road surface de-icing are
extremely corrosive. They accelerate corrosion
and deterioration of underbody components
such as the exhaust system, fuel and brake lines,
brake cables, floor pan and fenders.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and corro-
sion, which may be required in some areas, con-
sult a NISSAN dealer.
Appearance and care7-7

Seat beltsCheck that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheel Check for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimes Make 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* Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level. Brake and clutch fluid levels*
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 “Ex-
haust gas (carbon monoxide)” 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.
8-4Maintenance and do-it-yourself

BRAKE FLUID
Check the brake fluid level in the reservoir. If the
fluid level is below the MIN line or the brake
warning light comes on, add Genuine NISSAN
Super Heavy Duty Brake Fluid or equivalentDOT
3 fluid up to the MAX line. If fluid must be added
frequently, the system should be checked by a
NISSAN dealer.
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 equivalent DOT 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 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.

WARNING
●Operating the engine with the air
cleaner removed can cause you or oth-
ers 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
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 Service and Maintenance Guide” for
change intervals.
If replacement is required, see your NISSAN
dealer.
CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a washer
fluid or a mild detergent. Your windshield is clean
if beads do not form when rinsing with clear
water.
Clean each blade by wiping it with a cloth soaked
in a washer fluid or a mild detergent. Then rinse
the blades with clear water. If your windshield is
still not clear after cleaning the blades and using
the wiper, install new windshield wiper blades.

FUEL RECOMMENDATION
Use unleaded regular gasoline with an octane
rating of at least 87 AKI (Anti-Knock Index) num-
ber (Research octane number 91) .

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 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 levelroads, 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.
