1-40Safety — Seats, seat belts and supplemental restraint system
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 become dangerous projec-
tiles and cause injury if the front
air bag inflates.
. Do not place objects with sharp
edges on the seat. Also, do not
place heavy objects on the seat
that will leave permanent impres-
sions in the seat. Such objects
can damage the seat or occupant
classification sensor (pattern
sensor). This can affect the op-
eration of the air bag system and
result in serious personal injury.
. Do not use water or acidic clea-
ners (hot steam cleaners) on the
seat. This can damage the seat or
occupant classification sensor.
This can also affect the operation
of the air bag system and result in
serious personal injury. .
Immediately after inflation, sev-
eral front air bag system compo-
nents 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 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 electri-
cal system, suspension 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 per-
sonal injury. Tampering includes
changes to the steering wheel
and the instrument panel assem-
bly by placing material over the
steering wheel pad and above the
instrument panel or by installing
additional trim material around
the air bag system.
. Modifying 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 ad-
ditional trim material, such as
seat covers, on the seat that is
not specifically designed to as-
sure proper air bag operation.
Additionally, do not stow any
objects under the front passen-
ger seat or the seat cushion and
seatback. Such objects may inter-
fere with the proper operation of
the occupant classification sen-
sor.
. No unauthorized changes should
be made to any components or
wiring of the seat belt system.
This may affect the front air bag
system. Tampering with the seat
belt system may result in serious
personal injury.
. It is recommended you visit a
NISSAN dealer for work on and
around the front air bag. It is also
recommended you visit a NISSAN
dealer for installation of electrical
equipment. The Supplemental
Restraint System (SRS) wiring
harnesses* should not be modi-
fied or disconnected. Unauthor-
ized electrical test equipment
and probing devices should not

1-42Safety — Seats, seat belts and supplemental restraint system
bags and curtain air bags do not provide
restraint to the lower body.
The seat belts should be correctly worn
and the driver and passenger seated
upright as far as practical away from the
side air bag, and seated as far away as
practical from the door finishers and side
roof rails. The side air bags and curtain air
bags inflate quickly in order to help
protect the occupants. Because of this,
the force of the side air bags and curtain
air bags inflating can increase the risk of
injury if the occupant is too close to, or is
against, these air bag modules during
inflation. The side air bags and curtain air
bags will remain inflated for a short
period of time. For Coupe models, in a
rollover, the curtain air bags on both side-
impact situations, the curtain air bags will
remain inflated for a short period of time.
The side air bags and curtain air bags
operate only when the ignition switch is
in the ON position.
After placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The air bag
warning light will turn off after about 7
seconds if the systems are operational.
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 finisher and the front
seat. Such objects may become
dangerous projectiles and cause
injury if a side air bag inflates.
. Right after inflation, several side
air bags and curtain air bag sys-
tem 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 side air bag and curtain
air bag systems. This is to prevent
accidental inflation of the side air
bag and curtain air bag or da-
mage to side air bag and curtain
air bag systems.
. Do not make unauthorized
changes to your vehicle’s electri-
cal system, suspension system or
side panel. This could affect prop-
er operation of the side air bag
and curtain air bag systems. .
Tampering with the air bag sys-
tem may result in serious perso-
nal injury. For example, do not
change the front seats by placing
material near the seatback or by
installing additional trim materi-
al, such as seat covers, around
the side air bags.
. It is recommended you visit a
NISSAN dealer for work on and
around the pretensioner system.
It is also recommended you visit a
NISSAN dealer for installation of
electrical equipment. The SRS
wiring harnesses* should not be
modified or disconnected. Un-
authorized electrical test equip-
ment and probing devices should
not be used on the side-impact
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 sec-
tions in this Owner’s Manual.

5-30Starting and driving
The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip
based on vehicle speed (traction con-
trol function).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel
flashes so note the following: .
The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-15).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator light
illuminates to indicate the VDC sys-
tem is off. When the VDC switch is used to
turn off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non
slipping drive wheel. The VDC warning
light
flashes if this occurs. All other
VDC functions are off, and the VDC
warning 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.
See “Vehicle Dynamic Control (VDC) warn- ing light” (P.2-15) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-18).
The computer has a built-in diagnostic
feature that tests the system each time
you start the engine and move the vehicle
forward 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
indication 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 sur-
faces and always drive carefully.
. Do not modify the vehicle’s sus-
pension. If suspension parts such
as shock absorbers, struts,
springs, stabilizer bars, bushings
and wheels are not NISSAN re-
commended for your vehicle or
are extremely deteriorated, the
VDC system may not operate
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

.Replacement tires may have a
lower speed rating than the fac-
tory equipped tires, and may not
match the potential maximum
vehicle speed. Never exceed the
maximum speed rating of the
tire.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
All season tires
NISSAN specifies all season tires on some
models to provide good performance all
year, including snowy and icy road con-
ditions. All Season tires are identified by
ALL SEASON and/or M&S (Mud and Snow)
on the tire sidewall. Snow tires have
better snow traction than All Season tires
and may be more appropriate in some
areas.
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 trac-
tion rating M&S on the tire sidewall.
If you plan to operate your vehicle in
snowy or icy conditions, NISSAN recom-
mends 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
rating to the original equipment tires. If
you do not, it can adversely affect the
safety and handling of your vehicle.
Generally, snow tires will have lower
speed ratings than factory equipped tires
and may not match the potential max-
imum vehicle speed. Never exceed the
maximum speed rating of the tire.
If you install snow tires, they must be the
same brand, construction and tread pat-
tern on all four wheels, and the same
sizes as the original tires.
For additional traction on icy roads,
studded 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 sur-
faces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be
installed on 19-inch size tires. Doing
so will cause damage to the vehicle.
If you plan to use tire chains/cables,
you should install 18-inch size tires
on your vehicle.
Use of tire chains may be prohibited
according 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 manufacturer’s suggestions.
Use only SAE Class S chains. Class “S”
chains are used on vehicles with re-
stricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed
to meet the SAE standard minimum
clearances between the tire and the
closest vehicle suspension or body com-
ponent required to accommodate the

9-6Maintenance and schedules
Engine oil and oil filter:
Replace engine oil and oil filter at the
specified intervals. For recommended oil
grade and viscosity refer to “Capacities
and recommended fluids/lubricants”
(P.10-2).
Evaporative Emissions Control Vapor
Lines*:
Check vapor lines for leaks or looseness.
Tighten connections or replace parts as
necessary.
Fuel lines*:
Check the fuel hoses, piping and connec-
tions for leaks, looseness, or deterioration.
Tighten connections or replace parts as
necessary.
Spark plugs:
Replace at specified intervals. Install new
plugs of the type as originally equipped.
CHASSIS AND BODY MAINTENANCE
Brake lines and cables:
Visually inspect for proper installation.
Check for chafing, cracks, deterioration,
and signs of leaking. Replace any deterio-
rated or damaged parts immediately.
Brake pads and rotors:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or da-
maged parts immediately.Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deteriora-
tion, and damage. Tighten connections or
replace parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driv-
ing for prolonged periods in dusty condi-
tions, replace the filter more frequently.
Steering gear and linkage, axle and
suspension parts:
Check for damage, looseness, and leak-
age of oil or grease. Under severe driving
conditions, inspect more frequently.
Tire rotation:
Tires cannot be rotated, as the front tires
are a different size from the rear tires and
the direction of wheel rotation is fixed in
each tire.
Transmission fluid/oil, differential oil:
Visually inspect for signs of leakage at
specified intervals.
To help ensure smooth, safe and eco-
nomical driving, NISSAN provides two
maintenance schedules that may be
used, depending upon the conditions in
which you usually drive. These schedules
contain both distance and time intervals,
up to 120,000 miles (192,000 km)/144
months. For most people, the odometer
reading will indicate when service is
needed. However, if you drive very little,
your vehicle should be serviced at the
regular time intervals shown in the sche-
dule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING CONDI-
TIONS
Additional maintenance items for se-
vere operating conditions;
should be
performed on vehicles that are driven
under especially demanding conditions.
Additional maintenance items should be
performed if you primarily operate your
vehicle under the following conditions:
. Repeated short trips of less than 5
miles (8 km).
. Repeated short trips of less than 10
miles (16 km) with outside tempera-
tures remaining below freezing.
