TILT OPERATION (if so equipped)
WARNING
∙ Do not adjust the steering wheel while driving. You could lose control of your
vehicle and cause an accident. ∙ Do not adjust the steering wheel any
closer to you than is necessary for
proper steering operation and com-
fort. The driver’s air bag inflates with
great force. If you are unrestrained,
leaning forward, sitting sideways or
out of position in any way, you are at
greater risk of injury or death in a
crash. You may also receive serious or
fatal injuries from the air bag if you
are up against it when it inflates. Al-
ways sit back against the seatback
and as far away as practical from the
steering wheel. Always use the seat
belts.
Pull the lock lever toward the driver and
hold it to adjust the steering wheel up or
down to the desired position.
Release the lock lever to lock the steering
wheel in place.

STEERING WHEEL
3-14Pre-driving checks and adjustments

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙Park 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 shif t lever to N (Neu-
tral). For Automatic Transmission (A/T)
move the shif t lever to P (Park)
∙ Be sure the ignition key is in the OFF orLOCK position when performing any
parts replacement or repairs.
∙ If 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.
∙ It is advisable to secure or remove any loose clothing and remove any jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ If 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.
∙ Never get under the vehicle while it is supported only by a jack. If it is neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ On gasoline engine models, the fuel filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off.

MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

fuel fumes are evident, check for the cause
and have it corrected immediately.
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, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust may form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, refer to
the “Appearance and care” section of this
manual.
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, refer to
“General maintenance” in this section.
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual. NOTE:
NISSAN does not advocate the use of
non-OEM approved af termarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the af termar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by NISSAN.

FUEL RECOMMENDATION (for
QR25DE models)
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
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. ∙ Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
the warranty coverage.
∙ Under no circumstances should a leaded gasoline be used, because this
will damage the three-way catalyst.
10-4Technical and consumer information

WARNING
∙ Ethanol vapors are extremely flam-mable and could cause serious per-
sonal injury.
∙ Never have any smoking materials lit in or near the vehicle when removing
the fuel filler cap or filling the tank.
∙ Do not use E-85 as a cleaning agent and never use it near an open flame.
Fuel requirements
Your vehicle will operate on both unleaded
regular gasoline with an octane rating of at
least 87 AKI (Anti-Knock Index) number (Re-
search octane number 91), or E-85 fuel, or
any mixture of these two.
For the best starting and vehicle driveabil-
ity results, do not continually switch be-
tween E-85 and unleaded regular gasoline.
If you must switch fuels, NISSAN recom-
mends the following: ∙ do not switch when the fuel gauge indi- cates less than 1/4 full
∙ add more than 5 gallons of fuel
∙ operate the vehicle immediately af ter refueling for a period of at least 5 min-
utes NOTE:
When the ambient temperature is above
90°F (32°C), you may experience hard
starting and rough idle following start
up even if the above recommendations
are followed.
Starting
The characteristics of E-85 fuel make it un-
suitable for use when ambient tempera-
tures fall below 0°F (-18°C). In the range of
0°F (-18°C) to 32°F (0°C), you may experience
an increase in the time it takes for you en-
gine to start, and a deterioration in drivabil-
ity (sags and/or hesitations) until the en-
gine is fully warmed up.
Fuel consumption
Because E-85 fuel contains less energy per
gallon than gasoline, you will experience an
increase in fuel consumption. You can ex-
pect your fuel mileage to decrease by
about 30% compared to gasoline opera-
tion.
Replacement parts
Many components in your Flexible Fuel Ve-
hicle (FFV) are designed to be compatible
with ethanol. Always be sure that your ve-
hicle is serviced with correct ethanol com-
patible parts.
CAUTION
Replacing fuel system components
with non-ethanol compatible compo-
nents can damage your vehicle and
may also affect the warranty coverage.
Maintenance
If you operate your vehicle using E-85 fuel,
follow the correct maintenance log shown
in the “Maintenance and schedules” sec-
tion of this manual.
CAUTION
Do not use ethanol mixture greater
than 85% in your vehicle. It will cause
difficulty in cold starting and may affect
driveability.
