∙ Do not make unauthorized changesto your vehicle’s electrical system,
suspension system or side panel. This
could affect proper operation of the
side air bag and curtain air bag
systems.
∙ Tampering with the side air bag sys- tem may result in serious personal in-
jury. For example, do not change the
front and rear seats by placing mate-
rial near the seatbacks or by installing
additional trim material, such as seat
covers, around the side air bag.
∙ It is recommended that you visit a NISSAN dealer for work on and around
the side air bag and curtain air bag. It
is also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical
test equipment and probing devices
should not be used on the side air bag
or curtain air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion. When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the
buyer to the appropriate sections in this
Owner’s Manual.
Driver and passenger
supplemental knee air bag
The knee air bag is located in the knee
bolster, on the driver’s and passenger’s
side.
All of the information, cautions and
warnings in this manual apply and must
be followed. The knee air bag is designed
to inflate in higher severity frontal collisions,
although it may inflate if the forces in an-
other type of collision are similar to those of
a higher severity frontal impact. It may not
inflate in certain collisions.

∙ It is recommended that you visit aNISSAN dealer for work on and around
the knee air bag. It is also recom-
mended that you visit a NISSAN dealer
for installation of electrical equip-
ment. The SRS wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the knee air
bag system.
*The SRS wiring harness or connectors
are yellow or orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the knee air
bag system and guide the buyer to the
appropriate sections in this manual.Seat belt with pretensioner(s)
(front and rear outboard seats)

∙ If there is an impact to your vehiclefrom any direction, your Occupant
Classification Sensor (OCS) should be
checked to verif y it is still functioning
correctly. It is recommended that you
visit a NISSAN dealer for this service.
The OCS should be checked even if no
air bags deploy as a result of the im-
pact. Failure to verif y proper OCS
function may result in an improper air
bag deployment resulting in injury or
death.

FRONT-DOOR POCKETSSEATBACK POCKETS
The seatback pockets may be located on
the back of the driver’s and/or passenger’s
seats. The pockets can be used to store
maps.

Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or sof t bristled brush. Wipe
the vinyl and leather (if so equipped) sur-
faces with a clean, sof t cloth dampened in
mild soap solution, then wipe clean with a
dry, sof t cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather (if so equipped).
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water to
clean the meter and gauge lens.

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, the shif t lever in P (Park) position 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 positioning aids.
2. Secure the grommet holes into the po- sitioning aids 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
lever in the P (Park) position and with
the parking brake applied, fully apply
and release all pedals. The floor mat
must not interfere with pedal opera-
tion or prevent the pedal from return-
ing 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 aids.
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, refer to “Seat belt
maintenance” in the “Safety—Seats, seat
belts and supplemental restraint system”
section of this manual.
