may inflate if the forces in another type of
collision are similar to those of a higher severity
frontal impact. They may not inflate in certain
frontal collisions. Vehicle damage (or lack of it) is
not always an indication of proper supplemental
air bag operation.
The supplemental air bag system has dual stage
inflators for both the driver and passenger air
bags. The system monitors information from the
crash zone sensor, the diagnosis sensor unit and
seat belt buckle sensors that detect if the seat
belts are fastened, inflator operation is based on
the severity of a collision and whether the seat
belts are being used. Only one front air bag may
inflate in a crash, depending on the crash sever-
ity and whether the front occupants are belted or
unbelted. This does not indicate improper per-
formance of the system. If you have any ques-
tions about the performance of your air bag
system, please contact your NISSAN dealer.
When the supplemental front 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 irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
Supplemental front air bags, along with the use
of seat belts, help to cushion the impact force onthe face and chest of the front occupants. They
can help save lives and reduce serious injuries.
However, an inflating front air bag may cause
facial abrasions or other injuries. Front 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 steering wheel or instru-
ment panel. The supplemental front air bags
inflate quickly in order to help protect the front
occupants. Because of this, the force of the front
air bag inflating can increase the risk of injury if
the occupant is too close to, or is against the air
bag module during inflation. The air bag will
deflate quickly after the collision is over.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.
WARNING

Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant andthe steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the supplemental front air bag
inflates.

Right after inflation, several 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 front air bag sys-
tem. This is to prevent accidental in-
flation of the air bag or damage to
the air bag system.

Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end
structure. This could affect proper
operation of the supplemental air
bag system.

Tampering with the supplemental
front air bag system may result in
serious personal injury. Tampering

occupants.However, all of the information,
cautions and warnings in this manual still
apply and must be followed.The supplemen-
tal side air bags and curtain side-impact air bags
are designed to inflate in higher severity side
collisions, although they may inflate if the forces
in another type of collision are similar to those of
a higher severity side impact. They are designed
to inflate on the side where the vehicle is
impacted. They may not inflate in certain side
collisions. Vehicle damage (or lack of it) is not
always an indication of proper supplemental side
air bag and curtain side-impact air bag opera-
tion.
When the supplemental side air bag and curtain
side-impact air bag inflate, 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 irritation and choking. Those with a
history of a breathing condition should get fresh
air promptly.
Supplemental side air bags, along with the use
of seat belts, help to cushion the impact force on
the chest of the front occupants. Curtain side-
impact air bags help to cushion the impact force
to the head of occupants. They can help save
lives and reduce serious injuries. However, an
inflating side air bag and curtain side-impact air
bag may cause abrasions or other injuries.
Supplemental side air bags and curtain side-impact 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
side-impact air bag inflate quickly in order to
help protect the front occupants. Because of
this, the force of the side air bag and curtain
side-impact air bag 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 bag and curtain side-impact air bag
will deflate quickly after the collision is over.
After turning the ignition key to 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 fin-
isher and the front seat. Such objectsmay become dangerous projectiles
and cause injury if the side air bag
inflates.

Right after inflation, several side air
bag and curtain air bag system com-
ponents will be hot. Do not touch
them; you may severely burn your-
self.

No unauthorized changes should be
made to any components or wiring of
this side air bag and curtain side-
impact air bag system. This is to pre-
vent accidental inflation of the side
air bag and curtain side-impact air
bag or damage to the side air bag
and curtain side-impact air bag sys-
tem.

Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or side panel.
This could affect proper operation of
the supplemental side air bag and
curtain side-impact air bag system.

traction. The brake LSD system works when one
of the driving wheels is spinning on a slippery
surface. The brake LSD system brakes the spin-
ning wheel to distribute the driving power to the
other driving wheel.
If the vehicle is operated with the vehicle dy-
namic control system turned off, all VDC and
TCS functions will be turned off. The brake LSD
system and ABS will still operate with the VDC
system off. If the brake LSD system or the ABS
is activated, the slip indicator light will blink and
you may hear a clunk noise and/or feel a pulsa-
tion in the brake pedal. This is normal.
While the VDC system is operating, 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 prop-
erly.
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 vehicle dynamic control system
is designed to help improve driving
stability but does not prevent acci-
dents due to abrupt steering opera-
tion at high speeds or by careless or
dangerous driving techniques. Re-
duce vehicle speed and be especially
careful when driving and cornering
on slippery surfaces and always drive
carefully.

If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extremely
deteriorated, the vehicle dynamic
control system may not operate prop-
erly and the vehicle dynamic control
off indicator light may come on.

Do not modify the vehicle’s suspen-
sion. The vehicle dynamic control
system may not operate correctly.

If suspension parts such as shock
absorbers, struts, springs and bush-ings are not standard equipment or
are extremely deteriorated, the ve-
hicle dynamic control system may not
operate properly and the vehicle dy-
namic control off indicator light may
come on.

When driving on extremely inclined
surfaces such as higher banked cor-
ners, the vehicle dynamic control sys-
tem may not operate properly and the
vehicle dynamic control off indicator
light may come on. Do not drive on
these types of roads.

If the tires other than the recom-
mended ones are used, the vehicle
dynamic control system may not op-
erate properly or the vehicle dynamic
control off indicator light may come
on.

The vehicle dynamic control system
is not a substitute for winter tires or
tire chains on a snow covered road.

FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.ANTI-FREEZEIn the winter when it is anticipated that the
temperature will drop below 32°F (0°C), check
anti-freeze to assure proper winter protection.
For additional information, see “Engine Cooling
System” in the “8. Maintenance and do-it-
yourself” section.BATTERYIf the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain
maximum efficiency, the battery should be
checked regularly. For additional information,
see “Battery” in the “8. Maintenance and do-it-
yourself” section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without anti-
freeze, drain the cooling system by opening the
drain plug located under the radiator. Refill
before operating the vehicle. See “Engine cool-
ing system” in the “8. Maintenance and do-it-
yourself” section for changing engine coolant.
TIRE EQUIPMENT1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced 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. Please consult your
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 provinces
and states 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.
3. Tire chains may be used if desired. Make sure
they are of proper size for the tires on your
vehicle and are installed according to the
chain manufacturer’s suggestions. Use of tire
chains may be prohibited according to loca-
tion. Check the local laws before installing
tire chains. When installing tire chains, make
sure they are of proper size for the tires on
your vehicle and are installed according tothe 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 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 addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Never install tire chains on a T-type spare tire.
Do not use tire chains on dry roads.
SPECIAL WINTER EQUIPMENTIt is recommended that the following items be
carried in the vehicle during winter:

ground or four wheels on the ground
(forward or backward) as this may
cause serious and expensive damage
to the transmission.
If it is necessary to tow the vehicle
with the front wheels raised, always
use towing dollies under the rear
wheels.

When towing rear wheel drive mod-
els with the front wheels on the
ground or on towing dollies:
Turn the ignition key to the OFF po-
sition, and secure the steering wheel
in a straight ahead position with a
rope or similar device. Never secure
the steering wheel by turning the
ignition key to the LOCK position.
This may damage the steering lock
mechanism.
VEHICLE RECOVERY (Freeing a
stuck vehicle)Use the towing hook by installing it in the front of
the vehicle. (The rear has no towing points.)
After removing the front license plate (if so
equipped),1Remove the towing hook cover from the
bumper.
2Securely install the towing hook stored with
jacking tools.
Make sure that the hook is properly secured in
the stored place after use.
Tow chains or cables must be attached only
to the main structural members of the vehicle.

Pulling devices should be routed so they do
not touch any part of the suspension, steer-
ing, brake or cooling systems.

Always pull the cable straight out from the
front of the vehicle. Never pull on the vehicle
at an angle.

Pulling devices such as ropes or canvas
straps are not recommended for use in ve-
hicle towing or recovery.

Stand clear of a stuck vehicle.
WARNING
Do not spin your tires at high speed.
This could cause them to explode and
result in serious injury. Parts of your
vehicle could also overheat and be dam-
aged.

time you wash the vehicle body, but clean the
top regularly before it becomes quite dirty. Leav-
ing the soft top dirty or soiled for a long period
will cause deterioration to the quality of the top
material.
Remove dust or dirt on the soft top with a soft
brush or sponge, then rinse it with plenty of
clean water. When the top is quite dirty, wash
using a mild detergent, such as a general
cleaner especially made for a cloth top or a
general purpose dish-washing liquid, mixed with
clean, lukewarm (never hot) water. Rinse the top
again with plenty of clean water to remove all
traces of soap.
CAUTION

Do not use strong household soap,
strong chemical detergents, gaso-
line, solvents or any other similar
material.

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 fromhousehold 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 completelydrybefore opening the
top. Opening the top while it is wet or damp may
cause interior water damage, water stains or
mildew on the top.
WAXINGRegular waxing protects the paint surface and
helps retain new vehicle appearance. After wax-
ing, polishing is recommended to remove
built-up residue and to avoid a weathered ap-
pearance.
If you wish to wax your vehicle, only use a wax
specified for use over clear coats, such as
Nissan Liquid or Spray Wax. Your NISSAN
dealer can assist you in choosing the proper
product.

Wax your vehicle only after a thorough wash-
ing. Follow the instructions supplied with the
wax.

Do not use a wax containing any abrasives,
cutting compounds or cleaners that maydamage the vehicle finish.

If the surface does not polish easily, use a
road tar remover and wax again.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint
finish may dull the finish or leave swirl
marks.
REMOVING SPOTSRemove tar and oil spots, industrial dust, insects,
and tree sap as quickly as possible from the
surface of the paint to avoid lasting damage or
staining. Special cleaning products are available
at your NISSAN dealer or any automotive acces-
sory store.UNDERBODYIn areas where road salt is used in winter, the
underbody must be cleaned regularly. This will
prevent dirt and salt from building up and caus-
ing underbody and suspension corrosion. Be-
fore the winter period and again in the spring, the
underseal must be checked and, if necessary,
re-treated.GLASSUse 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

Snow tiresIf 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 maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.
For additional traction on icy roads, studded tires
may be used. However, some provinces and
states 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 CHAINSUse 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 of proper size for the tires on your
vehicle and are installed according to the chainmanufacturer’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 recom-
mended 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
undercarriage. If possible, avoid fully loading
your vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.

Never install tire chains on a T-type
spare tire.

Do not use the chains on dry roads.

Tire chains must be installed only on the
rear wheels and not on the front wheels.
CHANGING WHEELS AND TIRES
Tire rotationTires cannot be rotated in this vehicle, as front
tires are different size from rear tires and the
direction of wheel rotation is fixed in each tire.
A pin is on the front brake rotor to prevent the
rear wheels from being installed in place of the
front wheels. The spare tire can be installed in
place of the front and rear wheels. When install-
ing the spare tire in the front wheel, the hole in
the spare tire wheel must be aligned with the pin
on the brake rotor.

trailer hitch.

To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.

After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.

Regularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
When towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the Tire and Loading Information
label.

Trailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturers’
specifications.Safety chainAlways use a suitable chain between your ve-hicle and the trailer. The safety chain should be
crossed and should be attached to the hitch, not
to the vehicle bumper or axle. Be sure to leave
enough slack in the chain to permit turning
corners.
Trailer lightsTrailer lights should comply with federal and/or
local regulations. When wiring the vehicle for
towing, connect the stop and tail light pickup
into the vehicle electrical circuit at a point be-
tween the sensor and stop light or light switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Pre-towing tips
Be certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if it
has an unusual nose-up or nose-down con-dition; check for improper tongue load, over-
load, worn suspension or other possible
causes of these conditions.

Always secure items in the trailer to prevent
load shifts while driving.

Be certain your rear view mirrors conform to
all federal, state and/or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability, and braking per-
formance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive your vehicle at a moderate
speed.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if your vehicle is equipped with automatic
