Operating tips
∙ Keep the windows and moonroof (if soequipped) closed while the air condi-
tioner is in operation.
∙ Af ter parking in the sun, drive for two or three minutes with the windows open
to vent hot air from the passenger
compartment. Then, close the win-
dows. This allows the air conditioner to
cool the interior more quickly. ∙
The air conditioning system should
be operated for approximately
10 minutes at least once a month.
This helps prevent damage to the
system due to lack of lubrication.
∙ A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
∙ If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, refer to “If your vehicle
overheats” in the “In case of emer-
gency ” section of this manual.AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. The air re-
circulation (
) button should always
be in the OFF position for heating and
defrosting.

3. To help prevent the vehicle from rollinginto traffic when parked on an incline, it
is a good practice to turn the wheels as
illustrated.
∙ HEADED DOWNHILL WITH CURB
A:
Turn the wheels into the curb and
move the vehicle forward until the curb
side wheel gently touches the curb.
∙ HEADED UPHILL WITH CURB
B:
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
∙ HEADED UPHILL OR DOWNHILL, NO CURB
C:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK position and remove the key. The power assisted steering uses a hy-
draulic pump, driven by the engine, to as-
sist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at
low speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance will
be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.

CAUTION
∙ Do not push start this vehicle. The3-way catalyst may be damaged.
∙ Automatic transmission models can- not be push-started or tow-started.
Attempting to do so may cause trans-
mission damage.
∙ For manual transmission models, never try to start the vehicle by tow-
ing it. When the engine starts, the for-
ward surge could cause the vehicle to
collide with the tow vehicle.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause en-
gine damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
∙ Do not open the hood if steam is com- ing out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc. take the
following steps. 1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to N (Neutral) (manual trans-
mission) or to P (Park) (automatic trans-
mission).
Do not stop the engine. 2. Turn off the air conditioner. Open all the
windows, move the heater or air condi-
tioner temperature control to maxi-
mum hot and fan control to high
speed.
3. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. If
steam or coolant is escaping, turn off
the engine. Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
A. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN dealer for this service.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
∙ To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
∙ Never remove the radiator or engine coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
∙ Avoid direct skin contact with used coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep coolant out of the reach of chil- dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.

8-6Do-it-yourself

∙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 corrosion inhibitors. If not prop-
erly formulated with appropriate co-
solvents and corrosion inhibitors,
such methanol blends may cause fuel
system damage and/or vehicle per-
formance problems. At this time, suf-
ficient data is not available to ensure
that all methanol blends are suitable
for use in NISSAN vehicles.
If any driveability problems such as engine
stalling and difficult hot-starting are expe-
rienced af ter 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 re-
fueling. 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. U.S. government regula-
tions require fuel ethanol dispensing
pumps to be identified with small, square, orange and black label with the common
abbreviation or the appropriate percent-
age 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 ve-
hicle. U.S. government regulations require
fuel ethanol dispensing pumps to be iden-
tified by a small, square, orange and black
label with the common abbreviation or the
appropriate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting ad-
ditive. NISSAN does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMT
content, not all do, so you may have to
consult your gasoline retailer for more de-
tails.
Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-ample, fuel injector 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 sol-
vents 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 severe, 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 level roads, have a
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of
the vehicle, for which NISSAN is not re-
sponsible.
Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.

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.
FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so
equipped)
Your vehicle is designed to use (E-85) Fuel
Ethanol, “Regular” unleaded regular gaso-
line or any percentage of the two fuels
combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a
small, square, orange and black label
with the common abbreviation or the
appropriate percentage for that region.
CAUTION
Use of other fuels such as Fuel Metha-
nol may cause powertrain damage or a
loss of vehicle performance.
Under no circumstances should a
leaded gasoline be used, because this
will cause damage to the three-way
catalyst.
General information
This information is for Flexible Fuel Vehicles
(FFV) only. FFV vehicles can be identified by
the fuel filler door label that states Ethanol
(E-85) or Unleaded Gasoline Only. This sec-
tion only covers those subjects that are
unique to Flexible Fuel Vehicles.
CAUTION
Only vehicles with the E-85 filler door
label can operate on E-85. Fuel system
or other damage can occur if E-85 is
used in vehicles that are not designed
to run on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
