CAUTION
Do not allow the immobilizer system
key, which contains an electrical tran-
sponder, to come into contact with wa-
ter or salt water. This could affect sys-
tem function. When the doors are locked using one of the
following methods, the doors cannot be
opened using the inside or outside door
handles. The doors must be unlocked to
open the doors.
WARNING
• Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from uninten-
tionally opening the doors, and will
help keep out intruders.
• Before opening any door, always look
for and avoid oncoming traffic. •
To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
DOORS
3-4Pre-driving checks and adjustments

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.

AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle.
As with any vehicle, loss of control could
result in a collision with other vehicles or
objects or cause the vehicle to roll over,
particularly if the loss of control causes
the vehicle to slide sideways.
Be attentive at all times, and avoid driving
when tired. Never drive when under the in-
fluence of alcohol or drugs (including pre-
scription or over-the-counter drugs which
may cause drowsiness). Always wear your
seat belt as outlined in the “Safety – Seats,
seat belts and supplemental restraint sys- tem” section of this manual, and also in-
struct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.
In a rollover crash, an unbelted person is
significantly more likely to die than a
person wearing a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or lef t side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure be-
low. Please note that this procedure is only
a general guide. The vehicle must be driven
as appropriate based on the conditions of
the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course.
4. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle. 5. If there is nothing in the way, steer the
vehicle to follow the road while vehicle
speed is reduced. Do not attempt to
drive the vehicle back onto the road sur-
face until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to
stay in the appropriate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based
on vehicle, road or traffic conditions,
gradually slow the vehicle to a stop in
a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially
at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, see
Starting and driving5-9

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake and clutch fluid (if so equipped),
and windshield-washer fluid as fre-
quently as possible, or at least whenever
you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Lock all doors.
• Position seat and adjust head restraints/headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-9). 1. Apply the parking brake.
2.
Continuously Variable Transmission
model:
Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t lever is in any of the driving
positions.
Manual Transmission (M/T) model:
Move the shif t lever to N (Neutral). De-
press the clutch pedal to the floor.
The starter is designed not to operate
unless the clutch pedal is fully
depressed.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and the
clutch pedal (if so equipped) and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the igni-
tion switch in any position.
BEFORE STARTING THE ENGINE STARTING THE ENGINE
5-14Starting and driving

CAUTION
• Do not push start this vehicle. The
three-way catalyst may be
damaged.
• Continuously Variable Transmission
(CVT) models and Manual Transmis-
sion (M/T) cannot be push-started or
tow-started. Attempting to do so
may cause transmission damage.
• For Manual Transmission (M/T) mod-
els, never try to start the vehicle by
towing it. When the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle. 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.
WARNING
• Do not continue to drive if your ve-
hicle overheats. Doing so could cause
engine damage or a vehicle fire.
• To avoid the danger of being scalded,
never remove the coolant reservoir
cap while the engine is still hot. When
the coolant reservoir cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
• Do not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the shif t
lever to N (Neutral) (manual transmis-
sion) or to P (Park) (CVT).
Do not stop the engine.
2. Turn off the air conditioner (if so equipped). Open all the windows, move
the heater or air conditioner tempera-
ture control to maximum hot and fan
control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator 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 radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing
or loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time.

When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, theshif t lever in P (Park) position (Continu-
ously Variable Transmission models) or
the shif t lever in the N (Neutral) position
(manual transmission models) and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t le-
ver in the P (Park) position (Continuously
Variable Transmission models) or the
shif t lever in the N (Neutral) position
(manual transmission models) and with
the parking brake applied, fully apply and
release all pedals. The floor mat must
not interfere with pedal operation or
prevent the pedal from returning to its
normal position. It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle.
The illustration shows the location of the
floor mat positioning hooks.
SEAT BELTS
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely in the shade before using them. For
additional information, see “Seat belt main-
tenance” (P. 1-20).

WARNING
Do not allow wet seat belts to roll up in
the retractor. NEVER use bleach, dye or
chemical solvents to clean the seat
belts, since these materials may se-
verely weaken the seat belt webbing.MOST COMMON FACTORS
CONTRIBUTING TO VEHICLE
CORROSION
Most vehicle corrosion is caused by:
• The accumulation of moisture-retaining dirt and debris in body panel sections,
cavities, and other areas.
• Damage to paint and other protective coatings caused by gravel and stone
chips or minor traffic collisions.
ENVIRONMENTAL FACTORS
INFLUENCE THE RATE OF
CORROSION
Moisture
Accumulation of sand, dirt and water on
the vehicle 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 ar-
eas where the temperatures stay above
freezing and where atmospheric pollution
exists and road salt is used.
Temperature
High temperatures accelerate the rate of
corrosion 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 accelerates the corrosion process.
Road salt also accelerates the disintegra-
tion of paint surfaces.
PROTECT YOUR VEHICLE FROM
CORROSION
• Wash and wax your vehicle of ten to keepthe vehicle clean.
• Always check for minor damage to the paint and repair it as soon as possible.
• Keep drain holes at the bottom of the doors open to avoid water accumulation.
• Check the underbody for accumulation of sand, dirt or salt. If present, wash with
water as soon as possible.

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,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shif t lever
to N (Neutral). For CVT models, move
the shif t lever to P (Park).
• Be sure the ignition switch is in the
OFF or LOCK position when perform-
ing 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
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever 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 nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
• Because the fuel lines on gasoline
engine models are under high pres-
sure even when the engine is off, it is
recommended that you visit a
NISSAN dealer for service of the fuel
filter or fuel lines.
• Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without
warning, even if the ignition switch 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.
CAUTION
• Do not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down. •
Avoid contact with used engine oil
and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
• Never leave the engine or the trans-
mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, see
“Owner's Manual/Service Manual order in-
formation” (P. 10-25).
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, it is recommended
that you have it done by a NISSAN dealer.
