Manual shift mode
When the selector lever is shifted from D to the
manual shift gate with the vehicle stopped or
while driving, the transmission enters the manual
shift mode. Shift ranges can be selected manu-
ally.
In the manual shift mode, the shift range is dis-
played on the position indicator in the meter.
When shifting the shift lever to the manual shift
gate, the position indicator displays 1 (first) up to
6 (sixth) depending on vehicle speed.
Shift ranges up or down one by one as follows:
1,2,3,4,5,66 (Sixth):
Use this position for all normal forward driving at
highway speeds.
5 (Fifth):
Use this position when driving up long slopes, or
for engine braking when driving down long
slopes.
4 (Fourth) , 3 (Third) and 2 (Second):
Use for hill climbing or engine braking on downhill
grades.
M1 (First):
Use this position when climbing steep hills slowly
or driving slowly through deep snow, sand or
mud, or for maximum engine braking on steep
downhill grades.
cRemember not to drive at high speeds for
extended periods of time in lower than 4
range. This reduces fuel economy.
When shifting up:
Move the selector lever to the + (up) side. (Shifts
to higher range.)
When shifting down:
Move the selector lever to the2(down) side.
(Shifts to lower range.)cThe transmission will automatically down-
shift the gears. (For example, if you select the
3rd range, the transmission will shift down
between the 3rd and 1st gears.)
cMoving the selector lever rapidly to the same
side twice will shift the ranges in succession.
When canceling the manual shift mode:
Return the selector lever to the D (Drive) position
to return the transmission to the normal driving
mode.
cIn the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving perfor-
mance and reduces the chance of ve-
hicle damage or loss of control.
cIn the manual shift mode, the transmis-
sion may shift up automatically to a
higher range than selected if the en-
gine speed is too high. When the ve-
hicle speed decreases, the transmis-
sion automatically shifts down and
shifts to 1st gear before the vehicle
comes to a stop.

To back up, lift up on the shift lever rings1and
then move it to the R (Reverse) position after
stopping the vehicle completely.
The shift lever ring returns to its original position
when the shift lever is moved to the N (Neutral)
position.
If it is difficult to move the shift lever 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) .

cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
cDrive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
cAvoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
cAvoid unnecessary engine idling.
cKeep your engine tuned up.
cFollow the recommended periodic mainte-
nance schedule.
cKeep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
cKeep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.cWhen cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
cUse the recommended viscosity engine oil.

MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
cThe accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas.
cDamage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic accidents.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on the ve-
hicle body underside can accelerate corrosion.
Wet floor coverings will not dry completely inside
the vehicle, and should be removed for drying to
avoid floor panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas where
the temperatures stay above freezing and where
atmospheric pollution exists and road salt is
used.
Temperature
High temperatures accelerate the rate of corro-
sion to those parts which are not well ventilated.
Air pollution
Industrial pollution, the presence of salt in the air
in coastal areas, or heavy road salt use acceler-
ates the corrosion process. Road salt also accel-
erates the disintegration of paint surfaces.
TO PROTECT YOUR VEHICLE
FROM CORROSION
cWash and wax your vehicle often to keep the
vehicle clean.
cAlways check for minor damage to the paint
and repair it as soon as possible.
cKeep drain holes at the bottom of the doors
open to avoid water accumulation.
cCheck the underbody for accumulation of
sand, dirt or salt. If present, wash with water
as soon as possible.
CAUTION
cNEVER 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.cNever 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.

and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
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 defrosterCheck 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 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 a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” 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 imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
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, deformation, rot or loose
connections.
UnderbodyThe 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.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
cPark the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift lever to N (Neu-
tral) . For CVT models, move the selector
lever to P (Park) .
cBe sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
cNever leave the engine or the CVT re-
lated component harness connector
disconnected while the ignition switch
is in the ON position.
cNever connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.c
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
cIt is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
cAlways wear eye protection whenever
you work on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
cNever get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
cKeep smoking materials, flame and
sparks away from the fuel tank and
battery.cOn gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.CAUTION
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cAvoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN service manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage.If in doubt about any servicing,
have it done by a NISSAN dealer.
