PRECAUTIONS ON SRS
This SRS section contains important infor-
mation concerning the following systems:
∙ Driver and front passenger supplemen- tal front-impact air bag (NISSAN Ad-
vanced Air Bag System)
∙ Front seat-mounted side-impact supplemental air bag
∙ Roof-mounted curtain side-impact and rollover supplemental air bag
∙ Seat belt with pretensioner(s) (front seats)
Supplemental front-impact air bag system
The NISSAN Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
Front seat-mounted side-impact
supplemental air bag system
This system can help cushion the impact
force to the chest area of the driver and
front passenger in certain side-impact col-
lisions. The side air bags are designed to
inflate on the side where the vehicle is im-
pacted. Roof-mounted curtain side-impact and
rollover supplemental air bag system
This system can help cushion the impact
force to the head of occupants in the out-
board seating positions in certain side-
impact or rollover collisions. In a side im-
pact, the curtain air bags are designed to
inflate on the side where the vehicle is im-
pacted. In a rollover, curtain air bags are
designed to inflate and remain inflated for
a short time.
These supplemental restraint systems are
designed to
supplement the crash protec-
tion provided by the driver and front pas-
senger seat belts and are not a substitute
for them. Seat belts should always be cor-
rectly worn and the occupant seated a
suitable distance away from the steering
wheel, instrument panel and door finishers.
For additional information, instructions
and precautions on seat belt usage, refer to
“Seat belts” in this section.

– When replacing tires, install thespecified size of tires on all four
wheels.
– When installing a spare tire, make sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) in-
cludes electronic sensors, electric pumps,
hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature
that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates the ABS warning light on the
instrument panel. The brake system then
operates normally but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov
e5-10km/h (3 -
6 mph). The speed varies according to road
conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion in the brake pedal and hear a noise
from under the hood or feel a vibration
from the actuator when it is operating. This
is normal and indicates that the ABS is op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.

TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced in snowy and icy conditions. If
you operate your vehicle on snowy or
icy roads, NISSAN recommends the use
of MUD & SNOW or ALL SEASON TIRES
on all four wheels. It is recommended
that you visit a NISSAN dealer for the tire
type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing 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. 3. Tire chains may be used. For additional information, refer to “Tire chains” in the
“Do-it-yourself ” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
∙ A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
∙ A sturdy, flat board to be placed under the jack to give it firm support.
∙ A shovel to dig the vehicle out of snow- drif ts.
∙ Extra washer fluid to refill the windshield-washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
∙ Wet ice (0°C, 32°F and freezing rain),very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid driv-
ing on wet ice until the road is salted
or sanded. ∙ Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shif ting too fast, the drive wheels will
lose even more traction.
∙ Allow more stopping distance under these conditions. Braking should be
started sooner than on dry pavement.
∙ Allow greater following distances on slippery roads.
∙ Watch for slippery spots (glare ice). These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steering
maneuvers.
∙ Snow can trap dangerous exhaust gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
5-28Starting and driving

∙ The spare tire is designed for emer-gency use. For additional information
refer to “Wheels and tires” in the “Do-
it-yourself ” section of this manual.
∙ When reinstalling the spare tire bas- ket under the vehicle af ter use, be
sure that the hook engages the bas-
ket from the inside. If the spare tire
basket hook is not engaged properly,
there is an increased risk of the spare
tire separating from the vehicle in a
crash and causing injury.
Stowing the damaged tire
Securely store the damaged tire in the
cargo area.
Securely store the jack and tools in the
storage area.
Return the spare tire basket back to its
original position in the reverse order of re-
moval. For additional information, refer to
“Getting the spare tire and tools” in this sec-
tion. NOTE:
The spare tire basket cannot be used to
store the conventional tire.
WARNING
∙ Always make sure that the spare tire
and jacking equipment are properly
secured af ter each use. Such items
can become dangerous projectiles in
an accident or sudden stop.
∙ Make sure that the spare tire basket is properly secured in its original posi-
tion af ter removing the spare tire.
∙ The spare tire and small size spare tire are designed for emergency use. For
additional information, refer to
“Wheels and tires” in the “Do-it-
yourself ” section of this manual.

1. P: The “P” indicates the tire is de- signed for passenger vehicles
(not all tires have this informa-
tion).
2. Three-digit number (215): This number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge. 3. Two-digit number (65): This
number, known as the aspect
ratio, gives the tire’s ratio of
height to width.
4. R: The “R” stands for radial.
5. Two-digit number (15): This num- ber is the wheel or rim diameter
in inches. 6. Two- or three-digit number (95):
This number is the tire’s load in-
dex. It is a measurement of how
much weight each tire can sup-
port. You may not find this infor-
mation on all tires because it is
not required by law.
7. H: Tire speed rating. You should not drive the vehicle faster than
the tire speed rating.

Other Tire-related Terminology
In addition to the many terms that
are defined throughout this section,
Intended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears
manufacturer, brand, and/or model
name molding that is higher or
deeper than the same molding on
the other sidewall of the tire, or (2)
the outward facing sidewall of an
asymmetrical tire that has a particu-
lar side that must always face out-
ward when mounted on a vehicle.
TYPES OF TIRES
WARNING
∙ When changing or replacing tires, be sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. A NISSAN dealer may be
able to help you with information
about tire type, size, speed rating and
availability.
∙ Replacement tires may have a lower speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.
∙ Always use tires of the same type, size, brand, construction and tread
pattern on all four wheels. Failure to
do so may result in a circumference
difference between tires on the front
and rear axles which can cause the
Vehicle Dynamic Control (VDC) system
to malfunction resulting in personal
injury or death, excessive tire wear
and may damage the transmission
and differential gears. ∙ For additional information regarding
tires, refer to “Tire Safety Information”
(Canada) 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 condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S on the tire sidewall.
Snow tires have better snow traction than
All Season tires and may be more appropri-
ate 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 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.
Do-it-yourself8-37

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 Ca-
nadian provinces prohibit their use. Check
local, state and provincial laws before in-
stalling studded tires. Skid and traction ca-
pabilities of studded snow tires on wet or
dry surfaces may be poorer than that of
non-studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on 185/60R15 or 185/55R16 tires.
Installation of the tire chains/cables on
185/60R15 or 185/55R16 tires will cause
damage to the vehicle. Please use snow
tires instead of chains/cables if needed.
Never install tire chains on a TEMPO-
RARY USE ONLY spare tire.
CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the
tires every 8,000 km (5,000 miles).
For additional information on tire re-
placing procedures, refer to “Flat tire”
in the “In case of emergency” section
in this manual.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. Rec-
ommended types and sizes are shown in
“Wheels and tires” in the “Technical and con-
sumer information” section of this manual.
WARNING
∙ The use of tires other than those rec-ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, Vehicle Dynamic
Control (VDC) System, ground clear-
ance, body-to-tire clearance, tire
chain, clearance, speedometer cali-
bration, headlight aim and bumper
height. Some of these effects may
lead to accidents and could result in
serious personal injury. ∙ If your vehicle was originally
equipped with four tires that were the
same size and you are only replacing
two of the four tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and per-
sonal injury.
∙ If the wheels are changed for any rea- son, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear.
For additional information on wheel
off-set dimensions, refer to “Wheels
and tires” in the “Technical and con-
sumer information” section of this
manual. ∙ Do not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could
have structural damage and could fail
without warning.
∙ The use of retread tires is not recommended.
∙ For additional information regarding tires, refer to “Tire Safety Information”
(Canada) in the Warranty Information
Booklet.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
∙ For additional information regarding
tires, refer to “Tire Safety Information”
in the Warranty Information Booklet.
