5. Allow the seat belt to retract. Pull up onthe shoulder belt to remove any slack in
the belt. 6. Remove any additional slack from the
seat belt; press downward and rear-
ward firmly in the center of the child re-
straint with your knee to compress the
vehicle seat cushion and seatback while
pulling up on the seat belt.
7. Tighten the tether strap according to the manufacturer's instructions to remove
any slack. 8. Af ter attaching the child restraint, test it
before you place the child in it. Push it
from side to side while holding the child
restraint near the seat belt path. The
child restraint should not move more
than 1 inch (25 mm), from side to side. Try
to tug it forward and check to see if the
seat belt holds the restraint in place. If
the restraint is not secure, tighten the
seat belt as necessary, or put the re-
straint in another seat and test it again.
You may need to try a different child
restraint. Not all child restraints fit in all
types of vehicles.

3. The booster seat should be positionedon the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the booster
seat is removed. For additional infor-
mation, see “Head restraints/headrests”
(P. 1-11). If the seating position does not have an
adjustable head restraint/headrest and
it is interfering with the proper booster
seat fit, try another seating position or a
different booster seat.
4. Position the lap portion of the seat belt low and snug on the child’s hips. Be sure
to follow the booster seat manufactur-
er’s instructions for adjusting the seat
belt routing.
5. Pull the shoulder belt portion of the seat belt toward the retractor to take up ex-
tra slack. Be sure the shoulder belt is
positioned across the top, middle por-
tion of the child’s shoulder. Be sure to
follow the booster seat manufacturer’s
instructions for adjusting the seat belt
routing.
6. Follow the warnings, cautions and in- structions for properly fastening a seat
belt shown in “Three-point type seat belt
with retractor” (P. 1-19). 7. If the booster seat is installed in the front
passenger seat, place the ignition switch
in the ON position. The front passenger
air bag status light
(if so equipped)
may or may not illuminate, depending on
the size of the child and the type of
booster seat being used. For additional
information, see “Front passenger air
bag and status light” (P. 1-63).

knee air bag are 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 requir-
ing the air bag to be automatically turned
OFF under some conditions. Certain sen-
sors 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 up to
the approximate size and weight of a one
year old is properly restrained in the front
passenger seat, the NISSAN Advanced Air
Bag System is designed to turn the front
passenger air bag and passenger knee air
bag OFF. For a properly restrained child
who is larger than the approximate size
and weight of a one year old, the front pas-
senger air bag may or may not be auto-
matically turned OFF, depending on the
size of the child and the type of child re-
straint being used. Af ter installing the child
restraint and positioning the child, place
the ignition switch in the ON position: if the
front passenger air bag status light is illu-
minated, the front passenger air bag andpassenger knee air bag are OFF. If the front
passenger air bag status light is not illumi-
nated, the air bag will inflate in a crash.
Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined 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 occu-
pant takes his/her weight off the seat
cushion (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 front passen-
ger air bag and passenger knee air bag
OFF. Always be sure to be seated and wear-
ing the seat belt properly for the most ef-
fective protection by the seat belt and
supplemental air bag.
NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor is designed to operate as de-
scribed above to turn the front passenger
air bag and passenger knee air bag OFF for
specified child restraints as required by the
regulations. Failing to properly secure childrestraints and to use the ALR mode may
allow the restraint to tip or move in a colli-
sion or sudden stop. This can also result in
the passenger air bag and passenger knee
air bag inflating in a crash instead of being
OFF. For additional information, see “Child
restraints” (P. 1-28).
If the front passenger seat is not occupied,
the front passenger air bag and passenger
knee air bag are 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 infla-
tion, such as if a child is standing on the
seat, or if two children are on the seat, con-
trary to the instructions in this manual. Al-
ways be sure that you and all vehicle occu-
pants are seated and restrained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag and passenger knee air bag
are automatically turned OFF with the seat
occupied. The light will not illuminate when
the front passenger seat is unoccupied.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the front passen-
ger air bag and passenger knee air bag are

•If the ATP light is on, this indicates
that the automatic transmission P
(Park) position will not function and
the transfer case is in neutral.
• When parking, always make sure that
the 4WD shif t indicator light illumi-
nates and the parking brake is set.
Failure to engage the transfer posi-
tion in 2WD, 4H or 4LO could result in
the vehicle moving unexpectedly, re-
sulting in serious personal injury or
property damage.
• Shif t the 4WD switch into the 2WD, 4H
or 4LO position again to turn off the
ATP warning light when the shif t le-
ver is in the P position and the ATP
warning light is on. (Before shif ting
the 4WD switch into the 4LO position,
move the shif t lever to the N position
once, shif t the shif t lever into P again
and make sure the ATP warning light
is off.)
This light indicates that the automatic

the nearest service station for re-
pairs. Otherwise, have your vehicle
towed because driving it could be
dangerous.
• Pressing the brake pedal with the en-
gine stopped and/or a low brake
fluid level may increase your stop-
ping distance and braking will re-
quire greater pedal effort and pedal
travel.

Cap warning appears in the vehicle infor-
mation display. If the fuel-filler cap is loose
or missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off af ter a few driving
trips. If thelight does not turn off
af ter a few driving trips, have the vehicle
inspected. It is recommended that you
visit a NISSAN dealer for this service. You
do not need to have your vehicle towed
to the dealer.
• MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or decelera- tion.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on
steady. Have the vehicle inspected. It is rec-
ommended that you visit a NISSAN dealer for this service. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.
