WARNING
●Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
● Fuel may be under pressure. Turn the
cap a third of a turn, and wait for any
“hissing” sound to stop to prevent fuel
from spraying out and possibly causing
personal injury. Then remove the cap. ●
Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause the
malfunction indicator light to come on.
● Never pour fuel into the throttle body to
attempt to start your vehicle.
● Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
– Always place the container on the ground when filling.
– Do not use electronic devices when filling.
– Keep the pump nozzle in contact with the container while you are fill-
ing it.
– Use only approved portable fuel con- tainers for flammable liquid.

CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label, located in the
driver’s door opening.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check all 4 tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Starting and driving5-3

Manual shift mode
When the shift selector is in the Ds (Drive Sport)
position, the transmission is ready for the manual
shift mode. Shift ranges can be selected manu-
ally by moving the shift selector up (+) or down
(–) . To cancel the Ds mode, return shift selector
to the D (Drive) position. The transmission returns
to automatic driving mode.
When the shift selector is shifted from D (Drive)
to the manual shift gate
Awith the vehicle
stopped or while driving, the transmission enters
the manual shift mode. Shift ranges can be se-
lected manually. In the manual shift mode, the
shift range is displayed on the position indicator in the meter. When shifting the shift selector to
the manual shift gate, the position indicator dis-
plays 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⇔ 6
M6 (6th):
Use this position for all normal forward driving at
highway speeds.
M5 (5th):
Use this position when driving up long slopes, or
for engine braking when driving down long
slopes.
M4 (4th) , M3 (3rd) and M2 (2nd):
Use for hill climbing or engine braking on downhill
grades.
M1 (1st):
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. ● Remember not to drive at high speeds for
extended periods of time in lower than 6
range. This reduces fuel economy. When shifting up:
Move the shift selector to the + (up) side. (Shifts
to higher range.)
When shifting down:
Move the shift selector to the
(down) side.
(Shifts to lower range.)
● The 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.)
● Moving the shift selector rapidly to the same
side twice will shift the ranges in succession.
When canceling the manual shift mode:
Return the shift selector to the D (Drive) position
to return the transmission to the normal driving
mode. ● In 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.

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 upshift speeds
The following are suggested vehicle speeds for
shifting into a higher gear. These suggestions relate
to fuel economy and vehicle performance. Actual
upshift speeds will vary according to road condi-
tions, the weather and individual driving habits.

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 the
Exhaust 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.

information, refer to “Capacities and recom-
mended fuel/lubricants” in the “Technical and
consumer information” section of this manual.

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.
