sible.
Other supplemental front-impact air
bag precautions
WARNING
∙ Do not place any objects on the steer- ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the front air
bags inflate.
∙ Immediately af ter inflation, several front air bag system components will
be hot. Do not touch them; you may
severely 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,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
∙ Tampering with the front air bag sys- tem may result in serious personal in-
jury. Tampering includes changes to
the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad and
above the instrument panel or by in-
stalling additional trim material
around the air bag system.
∙ Removing or modif ying the front pas- senger seat may affect the function of
the air bag system and result in seri-
ous personal injury.
1-58Safety—Seats, seat belts and supplemental restraint system

∙ 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.
Driver’s side
LRS2599
Safety—Seats, seat belts and supplemental restraint system1-61

Vehicle damage (or lack of it) is not always
an indication of proper knee air bag opera-
tion.
When the knee air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. This smoke is not harmful and
does not indicate a fire. Care should be
taken not to inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.The knee air bag helps to cushion the im-
pact force on the knees of the driver and
passenger. It can help reduce serious inju-
ries. However, an inflating knee air bag may
cause abrasions or other injuries. The knee
air bag provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of
this, the force of the knee air bag inflating
can increase the risk of injury if the occu-
pant is too close to, or is against, this air bag
module during inflation. The knee air bag
will deflate quickly af ter the collision is over
OR the knee air bag will remain inflated for
a short time.
The knee air bag operates only when the
ignition switch is placed in the ON posi-
tion.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
∙ Do not place any objects between the
knee bolster and the driver’s or pas-
senger’s seat. Such objects may be-
come dangerous projectiles and
cause injury if a knee air bag inflates.
∙ Right af ter inflation, the knee air bag system components will be hot. Do
not touch them; you may severely
burn yourself.
∙ No unauthorized changes should be made to any components or wiring of
the knee air bag system. This is to pre-
vent damage to or accidental inflation
of the knee air bag system.
∙ Do not make unauthorized changes to your vehicle’s electrical system or
suspension system. This could affect
proper operation of the knee air bag
system.
∙ Tampering with the knee air bag sys- tem may result in serious personal in-
jury. For example, do not change the
driver or passenger knee bolster or
install additional trim material
around the knee air bag.

– Suspension parts other than thosedesignated as Genuine NISSAN
parts are used. (If the vehicle
height or the vehicle body inclina-
tion is changed, the system may
not detect an obstacle correctly.)
∙ Excessive noise (e.g., audio system volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, and the RAB sys-
tem warning light will illuminate in the ve-
hicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:
∙ Always keep the parking sensors
1
clean.
∙ If the parking sensors are dirty, wipe them off with a sof t cloth while being
careful to not damage them. ∙ Do not subject the area around the
parking sensors
1to strong impact.
Also, do not remove or disassemble the
parking sensors. If the parking sensors
and peripheral areas are deformed in
an accident, etc., have the sensors
checked. It is recommended that you
visit a NISSAN dealer for this service.
∙ Do not install any stickers (including transparent stickers) or accessories on
the parking sensors
1and their sur-
rounding areas. This may cause a mal-
function or improper operation.

5-90Starting and driving

When the vehicle information display is
used to turn off the system, the VDC sys-
tem still operates to prevent one drive
wheel from slipping by transferring power
to a non-slipping drive wheel. The
in-
dicator light flashes if this occurs. All other
VDC functions are off and the
indica-
tor light will not flash.
The VDC system is automatically reset to
ON when the ignition switch is placed in the
OFF position then back to the ON position.
The computer has a built-in diagnostic fea-
ture that tests the system each time you
start the engine and move the vehicle for-
ward or in reverse at a slow speed. When
the self-test occurs, you may hear a clunk
noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indica-
tion of a malfunction.
WARNING
∙ The VDC system is designed to help the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed and
be especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully.
∙ Do not modif y the vehicle’s suspen- sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the
indicator light may flash.
∙ If brake related parts such as brake pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC system
may not operate properly and
the
indicator light may
illuminate. ∙ If engine control related parts are not
NISSAN recommended or are ex-
tremely deteriorated, the
indica-
tor light may illuminate.
∙ When driving on extremely inclined surfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator light
may flash. Do not drive on these types
of roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash. This is not a malfunction. Re-
start the engine af ter driving onto a
stable surface.
∙ If wheels or tires other than the NISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator light
may flash.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road.

BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.
WARNING
∙ The VDC system is designed to helpthe driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed and
be especially careful when driving and
cornering on slippery surfaces and al-
ways drive carefully.
∙ Do not modif y the vehicle’s suspen- sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not NISSAN recommended for your

properly. This could adversely affect
vehicle handling performance, and
the
indicator light may flash. ∙ If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the VDC system
may not operate properly and
the
indicator light may
illuminate.
∙ If engine control related parts are not NISSAN recommended or are ex-
tremely deteriorated, the
