•Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.
• Tampering with the front air bag sys-
tem may result in serious personal
injury. 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 installing additional trim material
around the air bag system.
• Removing or modif ying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury. •
Modif ying or tampering with the
front passenger seat may result in
serious personal injury. For example,
do not change the front seats by
placing material on the seat cushion
or by installing additional trim mate-
rial, such as seat covers, on the seat
that are not specifically designed to
assure proper air bag operation. Ad-
ditionally, do not stow any objects
under the front passenger seat or the
seat cushion and seatback. Such ob-
jects may interfere with the proper
operation of the occupant classifica-
tion sensor (weight sensor).
• No unauthorized changes should be
made to any components or wiring
of the seat belt system. This may af-
fect the front air bag system. Tam-
pering with the seat belt system may
result in serious personal injury. •
It is recommended that you visit a
NISSAN dealer for work on and
around the front air bag. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electri-
cal test equipment and probing de-
vices should not be used on the air
bag system.
• A cracked windshield should be re-
placed immediately by a qualified re-
pair facility. A cracked windshield
could affect the function of the
supplemental air bag system.

WARNING
• Do not place any objects near the
seatback of the front seats. Also, do
not place any objects (an umbrella,
bag, etc.) between the front door fin-
isher and the front seat. Such objects
may become dangerous projectiles
and cause injury if a side air bag
inflates.
•
Right af ter inflation, several side air
bag and curtain air bag system com-
ponents 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 side air bag and curtain air bag
systems. This is to prevent damage
to or accidental inflation of the side
air bag and curtain air bag systems.
• Do not make unauthorized changes
to your vehicle's electrical system,

This could affect proper operation of
the curtain air bag systems. •
Tampering with the side air bag sys-
tem may result in serious personal
injury. For example, do not change
the front seats by placing material
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 installa-
tion of electrical equipment. The SRS
wiring harnesses* should not be
modified or disconnected. Unauthor-
ized electrical test equipment and
probing devices should not be used
on the side air bag or curtain air bag
systems.

Driver and front passenger
supplemental knee air bag
The knee air bag is located below the
steering column on the driver’s side, and in
the knee bolster on the front 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.
LRS3641
Driver’s side
Safety-Seats, seat belts and supplemental restraint system1-87

Vehicle damage (or lack of it) is not always an
indication of proper knee air bag operation.
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 position.
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
passenger’s seat. Such objects may
become 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
prevent damage to or accidental in-
flation 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
injury. For example, do not change
the driver or passenger knee bolster
or install additional trim material
around the knee air bag.

•Once the automatic brake control
operates, it does not operate again if
the vehicle approaches the same
obstacle.
• The automatic brake control can only
operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
• In the following situations, the RAB
system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad
weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep
hill.
– The vehicle’s posture is changed
(e.g., when driving over a bump).
– The vehicle is driven on a slippery
road.
– The vehicle is turned sharply by
turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN
recommended are used.
– The brakes are cold at low ambi-
ent temperatures or immediately
af ter driving has started. –
The braking force becomes poor
due to wet brakes af ter driving
through a puddle or washing the
vehicle.
• Turn the RAB system off in the follow-
ing conditions to prevent the occur-
rence of an unexpected accident
resulting from sudden system op-
eration:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The vehicle drives on an uneven
road surface.
– The vehicle is towing an object (if
so equipped).
–
Suspension parts other than those designated as Genuine NISSAN
parts are used. (If the vehicle height
or the vehicle body inclination is
changed, the system may not de-
tect an obstacle correctly.)
– If the vehicle is using an accessory
like a bike rack, or cargo carrier
that blocks the sensors. •
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 and the
warning message “System fault See Own-
er’s Manual” in the vehicle 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.
5-80Starting and driving

• The ABLS system uses automatic brak-ing to transfer power from a slipping drive
wheel to the wheel on the same axle with
more traction. The ABLS system applies
braking to the slipping wheel, which helps
redirect power to the other wheel.
• On 4–Wheel Drive models the ABLS sys- tem operates in both 4H and 4LO modes.
If 4WD mode is engaged, the ABLS sys-
tem operates for both drive axles. On
2–Wheel Drive vehicles, the ABLS system
operates on the drive axle only.
• The ABLS system is always on. In some conditions, the system may automati-
cally turn the ABLS system off. If the sys-
tem is automatically turned off, normal
brake function will continue. ABLS will
function even when the Vehicle Dynamic
Control system is turned off.
• The ABLS does not operate if both wheels on a drive axle are slipping.WARNING
• The ABLS system helps provide in-
creased traction, but will not prevent
accidents due to abrupt steering op-
eration or by careless driving or dan-
gerous driving practices. Reduce ve-
hicle speed and be especially careful
when driving and cornering on slip-
pery surfaces. Always 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 approved for your vehicle
or are extremely deteriorated, the
ABLS system may not operate prop-
erly. This could adversely affect ve-
hicle handling performance, and the
slip indicator light may illuminate.
•
If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are ex-
tremely deteriorated, the ABLS system
may not operate properly and the slip
indicator light may illuminate.
• If wheels or tires other than the
NISSAN recommended ones are
used, the ABLS system may not oper-
ate properly and the slip indicator
light may illuminate.

•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 deterio-
rated, the VDC system may not oper-
ate properly. This could adversely af-
fect vehicle handling performance,
and the

When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the
indicator
light may flash or theindicator
light may illuminate. 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 or theindicator light may
illuminate. This is not a malfunction.
Restart 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 oper-
ate properly and the
indicator
light may flash or theindicator
light may illuminate.
• 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 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 driv-
ing and cornering on slippery sur-
faces and always 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 deterio-
rated, the VDC system may not oper-

lights may illuminate.
5-122Starting and driving

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When installing
tire chains, make sure they are the proper
size for the tires on your vehicle and are
installed according to the chain manufac-
turer's suggestions.
Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tire
size. Other types may damage your vehicle.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chain must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. If possible,
avoid fully loading your vehicle when using
tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
Use only the 2WD range when driving on
clear paved roads.
