WARNING
●The front air bags ordinarily will not
inflate in the event of a side impact, rear
impact, rollover, or lower severity fron-
tal collision. Always wear your seat
belts to help reduce the risk or severity
of injury in various kinds of accidents.
●The front passenger air bag will not
inflate if the passenger air bag status
light is lit or if the front passenger seat
is unoccupied. See “Front passenger air
bag and status light” later in this
section.●The seat belts and the front air bags are
most effective when you are sitting well
back and upright in the seat. The front
air bags inflate with great force. Even
with the NISSAN Advanced Air Bag Sys-
tem, if you are unrestrained, leaning
forward, sitting sideways or out of posi-
tion 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
front air bag if you are up against it
when it inflates. Always sit back against
the seatback and as far away as practi-
cal from the steering wheel or instru-
ment panel. Always use the seat belts.●The driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
Advanced Air Bag System monitors the
severity of a collision and seat belt us-
age then inflates the air bags. Failure to
properly wear seat belts can increase
the risk or severity of injury in an
accident.
●The front passenger seat is equipped
with an occupant classification sensor
(pressure sensor) that turns the front
passenger air bag OFF under some
conditions. This sensor is only used in
this seat. Failure to be properly seated
and wearing the seat belt can increase
the risk or severity of injury in an acci-
dent. See “Front Passenger air bag and
status light” later in this section.
●Keep hands on the outside of the steer-
ing wheel. Placing them inside the
steering wheel rim could increase the
risk that they are injured when the front
air bag inflates.

flate if the forces in another type of collision are
similar to those of a higher severity frontal impact.
They may not inflate in certain frontal collisions.
Vehicle damage (or lack of it) is not always an
indication of proper front air bag system opera-
tion.
The NISSAN Advanced Air Bag System has dual
stage inflators. It also monitors information from
the crash zone sensor, the Air bag Control Unit
(ACU) , seat belt buckle sensors, occupant clas-
sification sensor (pressure sensor) and passen-
ger seat belt tension sensor. Inflator operation is
based on the severity of a collision and seat belt
usage for the driver. For the front passenger, it
additionally monitors the weight of an occupant
or object on the seat and seat belt tension. Based
on information from the sensors, only one front air
bag may inflate in a crash, depending on the
crash severity and whether the front occupants
are belted or unbelted. Additionally, the front
passenger air bag may be automatically turned
OFF under some conditions, depending on the
weight detected on the passenger seat and how
the seat belt is used. If the front passenger air bag
is OFF, the passenger air bag status light will be
illuminated (if the seat is unoccupied, the light will
not be illuminated, but the air bag will be off) . See
“Front passenger air bag and status light” later inthis section for further details. One front air bag
inflating does not indicate improper performance
of the system.
If you have any questions about your air bag
system, please contact NISSAN or your NISSAN
dealer. If you are considering modification of your
vehicle due to a disability, you may also contact
NISSAN. Contact information is contained in the
front of this Owner’s Manual.
When a front air bag inflates, a fairly loud noise
may be heard, followed by the release of smoke.
This smoke is not harmful and does not indicate a
fire. Care should be taken to not inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
Front air bags, along with the use of seat belts,
help to cushion the impact force on the face and
chest of the front occupants. They can help save
lives and reduce serious injuries. However, an
inflating front air bag may cause facial abrasions
or other injuries. Front air bags do not provide
restraint to the lower body.
Even with NISSAN advanced air bags, seat belts
should be correctly worn and the driver and pas-
senger seated upright as far as practical away
from the steering wheel or instrument panel. The
front air bags inflate quickly in order to help
protect the front occupants. Because of this, theforce of the front air bag inflating can increase the
risk of injury if the occupant is too close to, or is
against, the front air bag module during inflation.
The front air bags deflate quickly after a collision.
The front air bags operate only when the
ignition switch is in the ON or START posi-
tion.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

Front passenger air bag and status light
WARNING
The front passenger air bag is designed to
automatically turn OFF under some con-
ditions. Read this section carefully to
learn how it operates. Proper use of the
seat, seat belt and child restraints is nec-
essary for most effective protection. Fail-
ure to follow all instructions in this
manual concerning the use of seats, seat
belts and child restraints can increase the
risk or severity of injury in an accident.Status light
The front passenger air bag status lightoris located near the climate controls. The
light operates as follows:
●Unoccupied passenger’s seat: The
oris OFF and the front passenger air
bag is OFF and will not inflate in a crash.
●Passenger’s seat occupied by a small adult,
child or child restraint as outlined in this
section: The
orilluminates to
indicate that the front passenger air bag is
OFF and will not inflate in a crash.●Occupied passenger seat and the passen-
ger meet the conditions outlined in this sec-
tion: The light
oris OFF to in-
dicate that the front passenger air bag is
operational.
Front passenger air bag
The front passenger air bag is designed to auto-
matically turn OFF when the vehicle is operated
under some conditions as described below in
accordance with U.S. regulations. If the front
passenger air bag is OFF, it will not inflate in a
crash. The driver air bag and other air bags in your
vehicle are not part of this system.
The purpose of the regulation is to help reduce
the risk of injury or death from an inflating air bag
to certain front passenger seat occupants, such
as children, by requiring the air bag to be auto-
matically turned OFF. Certain sensors are used
to meet the requirements.
One sensor used is the occupant classification
sensor (pressure sensor) . It is in the bottom of the
front passenger seat cushion and is designed to
detect an occupant and objects on the seat by
weight. It works together with seat belt sensors
described later. For example, if a child is in the
front passenger seat, the Advanced Air Bag Sys-
tem is designed to turn the passenger air bag
OFF in accordance with the regulations. Also, if a
child restraint of the type specified in the regula-

tions is on the seat, its weight and the child’s
weight can be detected and cause the air bag to
turn OFF. Occupant classification sensor opera-
tion can vary depending on the front passenger
seat belt sensors.
The front passenger seat belt sensors are de-
signed to detect if the seat belt is buckled and the
amount of tension on the seat belt, such as when
it is in the Automatic Locking Retractor (ALR)
mode (child restraint mode) . Based on the
weight on the seat detected by the occupant
classification sensor and the belt tension de-
tected on the seat belt, the Advanced Air Bag
System determines whether the front passenger
air bag should be automatically turned OFF as
required by the regulations.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the passen-
ger air bag to be automatically turned OFF. For
small adults it may be turned OFF, however if the
occupant takes his/her weight off the seat cush-
ion (for example, by not sitting upright, by sitting
on an edge of the seat, or by otherwise being out
of position) , this could cause the sensor to turn
the air bag OFF. In addition, if the occupant
improperly uses the seat belt in the ALR mode
(child restraint mode) , this could cause the air
bag to be turned OFF. Always be sure to beseated and wearing the seat belt properly for the
most effective protection by the seat belt and
supplemental air bag.
NISSAN recommends that pre-teens and chil-
dren be properly restrained in a rear seat.
NISSAN also recommends that appropriate child
restraints and booster seats be properly installed
in a rear seat. If this is not possible, the occupant
classification sensor and seat belt sensors are
designed to operate as described above to turn
the front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and to
use the ALR mode (child restraint mode) may
allow the restraint to tip or move in an accident or
sudden stop. This can also result in the passen-
ger air bag inflating in a crash instead of being
OFF. See “Child restraints” earlier in this section
for proper use and installation.
If the front passenger seat is not occupied the
passenger air bag is designed not to inflate in a
crash. However, heavy objects placed on the
seat could result in air bag inflation, because of
the object’s weight detected by the occupant
classification sensor. Other conditions could also
result in air bag inflation, such as if a child is
standing on the seat, or if two children are on the
seat, contrary to the instructions in this manual.
Always be sure that you and all vehicle occupants
are seated and restrained properly.Using the passenger air bag status light, you can
monitor when the front passenger air bag is au-
tomatically turned OFF with the seat occupied.
The light will not illuminate when the front pas-
senger seat is unoccupied.
If an adult occupant is in the seat but the passen-
ger air bag status light is illuminated (indicating
that the air bag is OFF) , it could be that the
person is a small adult, or is not sitting on the seat
properly or not using the seat belt properly.
If a child restraint must be used in the front seat,
the passenger air bag status light may or may not
be illuminated, depending on the size of the child
and the type of child restraint being used. If the air
bag status light is not illuminated (indicating that
the air bag might inflate in a crash) , it could be
that the child restraint or seat belt is not being
used properly. Make sure that the child restraint is
installed properly, the seat belt is used properly
and the occupant is positioned properly. If the air
bag status light is not illuminated, reposition the
occupant or child restraint in a rear seat.
If the passenger air bag status light will not illu-
minate even though you believe that the child
restraint, the seat belts and the occupant are
properly positioned, the system may be sensing
an unoccupied seat (in which case the air bag is
OFF) . Your NISSAN dealer can check that the
system is OFF by using a special tool. However,

Seat belts with pretensioners (front
seats)
WARNING
●The pretensioners cannot be reused af-
ter activation. They must be replaced
together with the retractor and buckle
as a unit.
●If the vehicle becomes involved in a
frontal collision but a pretensioner is
not activated, be sure to have the pre-
tensioner system checked and, if nec-
essary, replaced by your NISSAN
dealer.
●No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to pre-
vent damage to or accidental activation
of the pretensioners. Tampering with
the pretensioner system may result in
serious personal injury.
●Work around and on the pretensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.●If you need to dispose of a pretensioner
or scrap the vehicle, contact a NISSAN
dealer. Correct pretensioner disposal
procedures are set forth in the appropri-
ate NISSAN Service Manual. Incorrect
disposal procedures could cause per-
sonal injury.
The pretensioner system activates in conjunction
with the front air bag system. Working with the
seat belt retractor, it helps tighten the seat belt
when the vehicle becomes involved in certain
types of collisions, helping to restrain front seat
occupants.
The pretensioner is encased within the seat belt
retractor. These seat belts are used the same way
as conventional seat belts.
When a pretensioner activates, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indicate a fire.
Care should be taken not to inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
After pretensioner activation, load limiters allow
the seat belt to release webbing (if necessary) to
reduce forces against the chest.If any abnormality occurs in the pretensioner sys-
tem, the supplemental air bag warning
light
will not come on, will flash intermit-
tently or will turn on for 7 seconds and remain on
after the ignition switch has been placed in the
ON or START position. In this case, the preten-
sioner system may not function properly. They
must be checked and repaired. Take your vehicle
to the nearest NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual.

ENGINE COOLANT TEMPERATURE
GAUGE
NOTE:
The ignition switch must be placed in the
ON position for the gauge to give a reading.
The gauge indicates the engine coolant tempera-
ture. The engine coolant temperature is within the
normal range when the reading is within the zone
1shown in the illustration.
The engine coolant temperature varies with the
outside air temperature and driving conditions.
CAUTION
If the gauge indicates a coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
the temperature. If the gauge is over the
normal range, stop the vehicle as soon as
safely possible. If the engine is over-
heated, continued operation of the ve-
hicle may seriously damage the engine.
See “If your vehicle overheats” in the “In
case of emergency” section for immediate
action required
ENGINE OIL PRESSURE GAUGE (if
so equipped)
The gauge indicates the engine lubrication sys-
tem oil pressure while the engine is running.
When the engine speed is high, the engine oil
pressure is also high. When the engine speed is
low, the gauge indicates lower oil pressure.
Engine oil pressure also changes based on en-
gine temperature. The oil pressure will be higher
when the engine is cold and lower when the
engine is warm.
