on their weight.
For additional information related to the normal
operation and troubleshooting of this occupant
classification sensor system, please refer to
“Normal operation” and “Troubleshooting” in this
section.
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, suchas children, by requiring the air bag to be auto-
matically turned OFF. Certain sensors are used to
meet the requirements.
The occupant classification sensor in this vehicle
is a weight sensor. It is designed to detect an
occupant and objects on the seat by weight. For
example, if a child is in the front passenger seat,
the NISSAN Advanced Air Bag System is de-
signed to turn the front passenger air bag OFF in
accordance with the regulations. Also, if a child
restraint of the type specified in the regulations is
on the seat, its weight and the child’s weight can
be detected and cause the air bag to turn OFF.
Front passenger seat adult occupants who are
properly seated and using the seat belt as out-
lined in this manual should not cause the front
passenger 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 cushion (for example, by not sitting up-
right, by sitting on an edge of the seat, or by
otherwise being out of position) , this could causethe sensor to turn the air bag OFF. Always be
sure to be seated 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 is 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 may
allow the restraint to tip or move in a collision or
sudden stop. This can also result in the passen-
ger air bag inflating in a crash instead of being
OFF. For additional information about proper use
and installation, refer to “Child restraints” in this
section.
1-52Safety—Seats, seat belts and supplemental restraint system

If the front passenger seat is not occupied, the
front 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 front passenger air bag status light, you
can monitor when the front passenger air bag is
automatically turned OFF.
If an adult occupant is in the seat but the front
passenger air bag status light is illuminated (indi-
cating 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 front 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 posi-tioned properly. If the air bag status light is still not
illuminated, reposition the occupant or child re-
straint in a rear seat.
If the front passenger air bag status light will not
illuminate even though you believe that the child
restraint, the seat belts and the occupant are
properly positioned, it is recommended that you
take your vehicle to a NISSAN dealer. A NISSAN
dealer can check system status by using a spe-
cial tool. However, until you have confirmed with
a dealer that your air bag is working properly,
reposition the occupant or child restraint in a rear
seat.
The NISSAN Advanced Air Bag System and front
passenger air bag status light will take a few
seconds to register a change in the front passen-
ger seat status. For example, if a large adult who
is sitting in the front passenger seat exits the
vehicle, the front passenger air bag status light
will go from OFF to ON for a few seconds and
then to OFF. This is normal system operation and
does not indicate a malfunction.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges area
of the instrument panel, will be illuminated (blink-
ing or steadily lit) . Have the system checked. It is
recommended that you visit a NISSAN dealer for
this service. Normal operation
In order for the occupant classification sensor
system to classify the front passenger based on
weight, please follow the precautions and steps
outlined below:
Precautions
● Make sure that there are no objects weigh-
ing over 2.2 lbs (1 kg) hanging on the seat or
placed in the seatback pocket.
● Make sure that a child restraint or other
object is not pressing against the rear of the
seatback.
● Make sure that a rear passenger is not push-
ing or pulling on the back of the front pas-
senger seat.
● Make sure that the front passenger seat or
seatback is not forced back against an ob-
ject on the seat or floor behind it.
● Make sure that there is no object placed
under the front passenger seat.
Steps 1. Adjust the seat as outlined in the “Seats” section of this manual. Sit upright, leaning
against the seatback, and centered on the
seat cushion with your feet comfortably ex-
tended to the floor.
Safety—Seats, seat belts and supplemental restraint system1-53

2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seatbelts” section of this manual. Front passen-
ger seat belt buckle status is monitored by
the occupant classification system, and is
used as an input to determine occupancy
status. So, it is highly recommended that the
front passenger fasten their seat belt.
4. Remain in this position for 30 seconds al- lowing the system to classify the front pas-
senger before the vehicle is put into motion.
5. Ensure proper classification by checking the front passenger air bag status light.
NOTE:
This vehicle’s occupant classification sen-
sor system generally keeps the classifica-
tion locked during driving, so it is important
that you confirm that the front passenger is
properly classified prior to driving. How-
ever, the occupant classification sensor
may recalculate the weight of the occupant
under some conditions (both while driving
and when stopped) , so front passenger
seat occupants should continue to remain
seated as outlined above. Troubleshooting
If you think the front passenger air bag status light
is incorrect:
1. If the light is ON with an adult occupying the front passenger seat:
● Occupant is a small adult — the air bag light
is functioning as intended. The front passen-
ger air bag is suppressed.
However, if the occupant is not a small adult, then
this may be due to the following conditions that
may be interfering with the weight sensors: ● Occupant is not sitting upright, leaning
against the seatback, and centered on the
seat cushion with his/her feet comfortably
extended to the floor.
● A child restraint or other object pressing
against the rear of the seatback.
● A rear passenger pushing or pulling on the
back of the front passenger seat.
● Forcing the front seat or seatback against an
object on the seat or floor behind it.
● An object placed under the front passenger
seat.
● An object placed between the seat cushion
and center console or between the seat
cushion and the door. If the vehicle is moving, please come to a stop
when it is safe to do so. Check and correct any of
the above conditions. Restart the vehicle and
wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON after this, the person should
be advised not to ride in the front passenger seat
and the vehicle should be checked as soon as
possible. It is recommended that you visit a
NISSAN dealer for this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front passen-
ger seat.
This may be due to the following conditions
that may be interfering with the weight sen-
sors:
● Small adult or child is not sitting upright,
leaning against the seatback, and centered
on the seat cushion with his/her feet com-
fortably extended to the floor.
● The child restraint is not properly installed,
as outlined in the “Child restraints” section of
this manual.
1-54Safety—Seats, seat belts and supplemental restraint system

●An object weighing over 2.2 lbs (1 kg) hang-
ing on the seat or placed in the seatback
pocket.
● A child restraint or other object pressing
against the rear of the seatback.
● A rear passenger pushing or pulling on the
back of the front passenger seat.
● Forcing the front seat or seatback against an
object on the seat or floor behind it.
● An object placed under the front passenger
seat.
● An object placed between the seat cushion
and center console.
If the vehicle is moving, please come to a stop
when it is safe to do so. Check and correct any of
the above conditions. Restart the vehicle and
wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially. If the light is still OFF after this, the small adult,
child or child restraint should be repositioned in
the rear seat and the vehicle should be checked
as soon as possible. It is recommended that you
visit a NISSAN dealer for this service.
3. If the light is OFF with no front passenger and no objects on the front passenger seat,
the vehicle should be checked. It is recom-
mended that you visit a NISSAN dealer as
soon as possible.
Other supplemental front-impact air bag
precautions
WARNING
● Do not place any objects on the steering
wheel pad or on the instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause
injury if the front air bags inflate.
● Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself. ●
No unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This is
to prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system.
● Do not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the front air bag system.
● Tampering with the front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and above
the instrument panel or by installing
additional trim material around the air
bag system.
● Removing or modifying the front pas-
senger seat may affect the function of
the air bag system and result in serious
personal injury.

When pretensioner(s) activate, 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 the pretensioner(s’) activation, load limiters
allow the seat belt to release webbing (if neces-
sary) to reduce forces against the chest.
The supplemental air bag warning light
is
used to indicate malfunctions in the pretensioner
system. For additional information, refer to
Supplemental air bag warning light in this sec-
tion. If the operation of the supplemental air bag
warning light indicates there is a malfunction,
have the system checked. It is recommended that
you visit a NISSAN dealer for this service.
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.

2-52Instruments and controls

NISSAN VEHICLE IMMOBILIZER
SYSTEM KEYS
You can only drive your vehicle using the Intelli-
gent Keys which are registered to the NISSAN
Vehicle Immobilizer System components in your
vehicle.
The mechanical key can be used for all the locks.
Never leave the keys in the vehicle.
Additional or replacement keys:
If you still have a key, the key number is not
necessary when you need extra NISSAN Vehicle
Immobilizer System keys. Your existing key can
be duplicated without knowing the key number.
As many as four NISSAN Vehicle Immobilizer
System keys can be used with one vehicle. You
should bring all NISSAN Vehicle Immobilizer Sys-
tem keys that you have to the NISSAN dealer for
registration. This is because the registration pro-
cess will erase the memory of all key codes
previously registered into the NISSAN Vehicle
Immobilizer System. After the registration pro-
cess, these components will only recognize keys
coded into the NISSAN Vehicle Immobilizer Sys-
tem during registration. Any key that is not given
to the dealer at the time of registration will no
longer be able to start your vehicle.
CAUTION
Do not allow the immobilizer system key,
which contains an electrical transponder,
to come into contact with water or salt
water. This could affect system 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 unintentionally open-
ing 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 inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of other or pets unattended in your ve-
hicle. Additionally, the temperature in-
side a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death or
people and pets.

INTERIOR TRUNK LID RELEASE
WARNING
Closely supervise children when they are
around cars to prevent them from playing
and becoming locked in the trunk where
they could be seriously injured. Keep the
car locked, with the rear seatback and
trunk lid securely latched when not in use,
and prevent children’s access to car keys.
The interior trunk lid release mechanism provides
a means of escape for children and adults in the
event they become locked inside the trunk. To open the trunk from the inside, pull the illumi-
nated release handle until the lock releases and
push up on the trunk lid. The release handle is
made of a material that glows in the dark after a
brief exposure to ambient light.
The handle is located inside the trunk compart-
ment on the interior of the trunk lid.
INTERIOR TRUNK ACCESS
The trunk can be accessed from the passenger
side of the rear seat.
The rear seat can be locked using the mechanical
key to prevent unauthorized access. For addi-
tional information, refer to “Keys” in this section.

fold-down position. Use of these areas
by passengers without proper restraints
could result in serious injury or death in
an accident or sudden stop.
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
● When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched posi-
tion. If they are not completely secured,
passengers may be injured in an acci-
dent or sudden stop.
● Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched

3-32Pre-driving checks and adjustments

WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear

EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death. ●
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
● Do not run the engine in closed spaces
such as a garage.
● Do not park the vehicle with the engine
running for any extended length of time.
● Keep the rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
one of these open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the trunk lid or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle. ●
The exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
