SEAT BELTS WITH PRETENSIONERS
(front seats)
WARNING
.The pretensioners cannot be reused
after activation. They must be re-
placed together with the retractor
and buckle as a unit.
. If the vehicle becomes involved in a
collision but a pretensioner is not
activated, be sure to have the pre-
tensioner system checked and, if necessary, replaced by a NISSAN
dealer.
. No unauthorized changes should be
made to any components or wiring
of the pretensioner system. This is
to prevent damage to or accidental
activation of the pretensioners.
Tampering with the pretensioner
system may result in serious perso-
nal injury.
. Work around and on the preten-
sioner system should be done by a

The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.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 control 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 conditions) .
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) warning
light” (P.2-15).
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates to
indicate the VDC system 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 lightwill 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) warning
light” (P.2-15) and “Vehicle Dynamic Control
(VDC) off indicator light” (P.2-17).
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 slip-
pery surfaces and always drive care-
fully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN recom-
mended for your vehicle or are
extremely deteriorated, the VDC
system may not operate properly.
This could adversely affect vehicle
handling performance, and the VDC
warning light
may illuminate.

VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM

6-22In case of emergency
.Always pull the cable straight out
from the front of the vehicle. Never
pull on the vehicle at an angle.
. Pulling devices should be routed so
they do not touch any part of the
suspension, steering, brake or cool-
ing systems.
. Pulling devices such as ropes or
canvas straps are not recommended
for use in vehicle towing or recov-
ery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud, etc.,
use the following procedure:
1. Turn off the Vehicle Dynamic Control (VDC)
system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and back- ward.
.Shift back and forth between R (Reverse)
and D (Drive) (automatic transmission
models) or 1st and R (Reverse) (manual
transmission models) .
.Apply the accelerator as little as possibleto maintain the rocking motion.
.Release the accelerator pedal beforeshifting between R (Reverse) and D
(Drive) (automatic transmission models)
or 1st and R (Reverse) (manual transmis-
sion models) .
.Do not spin the tires above 35 MPH (55 km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional towing service
to remove the vehicle.

7-4Appearance and care
.If glass cleaner gets on the soft top,
immediately wash it off with clean
water.
. Do not apply direct water pressure,
such as high pressured water from
household hoses, on the lining of
the soft top and vehicle body, as this
may cause water to leak into the
inside of your vehicle.
After cleaning, always be sure the top and its
storage are completely drybefore opening the
top. Opening the top while it is wet or damp may
cause interior water damage, water stains or
mildew on the top.
WAXING
Regular waxing protects the paint surface and
helps retain new vehicle appearance. Polishing
is recommended to remove built-up wax residue
and to avoid a weathered appearance before
reapplying wax.
A NISSAN dealer can assist you in choosing the
proper product.
. Wax your vehicle only after a thorough
washing. Follow the instructions supplied
with the wax.
. Do not use a wax containing any abrasives,
cutting compounds or cleaners that may damage the vehicle finish.
Machine compound or aggressive polishing on a
base coat/clear coat paint finish may dull the
finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust,
insects, and tree sap as quickly as possible
from the paint surface to avoid lasting damage
or staining. Special cleaning products are
available at a NISSAN dealer or any automotive
accessory stores.
UNDERBODY
In areas where road salt is used in winter, the
underbody must be cleaned regularly. This will
prevent dirt and salt from building up and
causing the acceleration of corrosion on the
underbody and suspension. Before the winter
period and again in the spring, the underseal
must be checked and, if necessary, re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for glass
to become coated with a film after the vehicle is
parked in the hot sun. Glass cleaner and a soft
cloth will easily remove this film.
CAUTION
. When cleaning the inside of the
windows, do not use sharp-edged
tools, abrasive cleaners or chlorine-
based disinfectant cleaners. They
could damage the electrical conduc-
tors, radio antenna elements or rear
window defroster elements.
. If glass cleaner gets on the soft top,
immediately wash it off with clean
water (Roadster models) .
WHEELS
Wash the wheels when washing the vehicle to
maintain their appearance.
.Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
. Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
. NISSAN recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.

8-36Maintenance and do-it-yourself
All season tires
NISSAN specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. 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 appro-
priate 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.
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 notmatch the potential maximum 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 pattern 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 cap-
abilities 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 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 instal-
ling 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 restricted 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 component required
to accommodate the use of a winter traction
device (tire chains or cables) . The minimum
clearances are determined using the factory
equipped tire size. Other types may damage
your vehicle. Use chain tensioners when re-
commended 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.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
