The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the Service and Maintenance
Guide. When replacing the filter, wipe the inside
of the air cleaner housing and the cover with a
damp cloth.
WARNING
Operating the engine with the air
cleaner removed can cause you orothers to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.
Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.

CHECKING PARKING BRAKEFrom the released position, pull the parking
brake lever up slowly and firmly. If the number of
clicks is out of the range listed above, see your
NISSAN dealer.
CHECKING BRAKE PEDALWith the engine running, check the distance
between the upper surface of the pedal and the
metal floor. If it is out of the range shown above,
see your NISSAN dealer.Self-adjusting brakesYour vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe disc brake pads on your vehicle have au-
dible wear indicators. When a brake pad re-
quires replacement, it will make a high pitched
scraping or screeching sound when the vehicle
is in motion whether or not the brake pedal is
depressed. Have the brakes checked as soon as
possible if the wear indicator sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect
the function or performance of the brake system.
Proper brake inspection intervals should
be followed.For additional information, see the
appropriate maintenance log shown in the Ser-
vice and Maintenance Guide.

Xenon headlight bulb:
WARNINGHIGH VOLTAGE
When xenon headlights are on, they
produce a high voltage. To prevent an
electric shock, never attempt to modify
or disassemble the headlight assembly.
Always have your xenon headlights re-
placed at a NISSAN dealer. For addi-
tional information, see “Headlight and
turn signal switch” in the “2. Instru-
ments and controls” section.
Halogen headlight bulb:
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. A
bulb can be replaced from under the engine
compartment without removing the headlight
assembly.
CAUTION
High pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.
When handling the bulb, do not touch
the glass envelope.
Do not touch the bulb.
Use the same number and wattage as
originally installed:
Bulb no. (Wattage)
D2R (35W) - Xenon low-beam

TIRE PRESSURE
Tire inflation pressureCheck the pressure of the tires (including the
spare) often and always prior to long distance
trips. The recommended tire pressure specifica-
tions are shown on the Tire and Loading Infor-
mation label under the “Recommended Cold
Tire Inflation Pressure” heading. The Tire and
Loading Information label is affixed to the driver
side center pillar. Tire pressures should be
checked regularly because:
Most tires naturally lose air over time.
Tires can lose air suddenly when driven over
potholes or other objects or if the vehicle
strikes a curbwhile parking.
The tire pressures should be checked when the
tires are cold. The tires are considered COLD
after the vehicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km) at
moderate speeds.
Incorrect tire pressure, including under in-
flation, may adversely affect tire life and
vehicle handling.
WARNING
Improperly inflated tires can fail sud-
denly and cause an accident.
The vehicle capacity weight is indi-
cated on the Tire and Loading Infor-
mation label. Do not load your ve-
hicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire mal-
function, or unfavorable handling
characteristics and could also lead to
a serious accident. Loading beyond
the specified capacity may also result
in a malfunction of other vehicle
components.
Before taking a long trip, or when-
ever you heavily load your vehicle,
use a tire pressure gauge to ensure
that the tire pressures are at the
specified level.
Do not drive your vehicle over 85
MPH (137 km/h) unless it is equipped
with high-speed rated tires. Drivingfaster than 85 MPH (137 km/h) may
result in tire failure, loss of control
and possible injury.
For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Low tire pressure warning system (if
so equipped)The low tire pressure warning system displays
the tire pressure of all tires (except the spare tire)
on the trip computer by sending a signal from a
sensor that is installed in each wheel. For more
details, refer to “Trip computer” and “Low tire
pressure warning light” in the “2. Instruments
and controls” section, “Low tire pressure warn-
ing system” in the “5. Starting and driving”
section, and “Flat tire” in the “6. In case of
emergency” section. If the tire pressure dis-
played on the trip computer is lower than the
COLD tire pressure shown on the Tire and
Loading Information label, check the pressure of
all four tires and adjust them to the COLD tire
pressure. The low tire pressure warning system
will activate only when the vehicle is driven at
speeds above 20 MPH (32 km/h).

3Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire.
Tire manufacturers also must indicate the
materials in the tire, which include steel,
nylon, polyester, and others.
4Maximum permissible inflation pressure
This number is the greatest amount of air
pressure that should be put in the tire. Do not
exceed the maximum permissible inflation
pressure.
5Maximum load rating
This number indicates the maximum load in
kilograms and pounds that can be carried by
the tire. When replacing the tires on the
vehicle, always use a tire that has the same
load rating as the factory installed tire.
6Term of “tubeless” or “tube type”
Indicates that the tire requires an inner tube
(“tube type”) or not (“tubeless”).
7The word “radial”
The word “radial” is shown, if the tire has a
radial structure.
8Manufacturer or Brand name
Manufacturer or Brand name is shown.
Other tire-related terminologyIn addition to the many terms that are definedthroughout this section, Intended Outboard
Sidewall is (1) the sidewall that contains a
whitewall, bears white lettering or bears manu-
facturer, 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
racing sidewall of an asymmetrical tire that has a
particular side that must always face outward
when mounted on a vehicle.
TYPES OF TIRES
WARNING
When changing or replacing tires, be
sure all four tires are of the same
type (for example, summer, all sea-
son or snow) and construction. Your
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.For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
All season tiresNISSAN specifies all season tires on some
models to provide good performance for use all
year round, 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 appropriate in some
areas.Summer tiresNISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance in snow and ice will be
substantially reduced. Summer tires do not have
the tire traction rating M&S on the tire sidewall.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires on all four wheels.

Tire wear and damage
WARNING
Tires should be periodically in-
spected for wear, cracking, bulging,
or objects caught in the tread. If ex-
cessive wear, cracks, bulging, or
deep cuts are found, the tire should
be replaced.
The original tires have a built-in tread
wear indicator. When the wearindicator is visible, the tire should be
replaced.
Improper service for a spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact your NISSAN dealer.
For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tiresWhen replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. See “Specifications” in the “9. Tech-
nical and consumer information” section for rec-
ommended types and sizes of tires and wheels.
WARNING
The use of tires other than those
recommended 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, ground clearance,
body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
If the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.
When a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN
dealer as soon as possible for tire

replacement and/or system reset-
ting. (For models with the low tire
pressure warning system)
Do not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
The use of retread tire is not recom-
mended.
For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Wheel balanceUnbalanced 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 performed
with the wheels off the vehicle. Spin balancing
the front wheels on the vehicle could lead to
transmission damage.For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information booklet.
Care of wheelsWash 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.
Do not use abrasive cleaners when washing
the wheels.
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.Spare tire (T-type spare tire)Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
CAUTION
The T-type spare tire should be used
only for emergency. It should be re-
placed by the standard tire at the first
opportunity.
Drive carefully while the T-type spare
tire is installed.
Avoid sharp turns and abrupt braking
while driving.
Periodically check the T-type spare
tire inflation pressure, and always
keep it at 60 psi (420 kPa, 4.2 bar).
Do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
Do not use tire chains on a T-type
spare tire. Tire chains will not fit
properly on the T-type spare tire and
may cause damage to the vehicle.
Tire tread of the T-type spare tire will
wear at a faster rate than the original
tire. Replace the T-type spare tire as
soon as the tread wear indicators

WARNING
It is extremely dangerous to ride in a
cargo area inside of a vehicle. In a
collision, people riding in these areas
are more likely to be seriously in-
jured or killed
Do not allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
Be sure everyone in your vehicle is in
a seat and using a seat belt properly.TERMSIt is important to familiarize yourself with the
following terms before loading your vehicle:
CurbWeight (actual weight of your vehicle) -
vehicle weight including: standard and op-
tional equipment, fluids, emergency tools,
and spare tire assembly. This weightdoes
notinclude passengers and cargo.
GVW (Gross Vehicle Weight) - curbweight
plus the combined weight of passengers and
cargo.GVWR (Gross Vehicle Weight Rating) -
maximum total combined weight of the un-
loaded vehicle, passengers, luggage, hitch,
trailer tongue load and any other optional
equipment. This information is located on the
F.M.V.S.S. label.
GAWR (Gross Axle Weight Rating) - maxi-
mum weight (load) limit specified for the front
or rear axle. This information is located on the
F.M.V.S.S. label.
GCWR (Gross Combined Weight rating) -
The maximum total weight rating of the ve-
hicle, passengers, cargo, and trailer.
Vehicle Capacity Weight, Load limit, Total
load capacity - maximum total weight limit
specified of the load (passengers and cargo)
for the vehicle. This is the maximum com-
bined weight of occupants and cargo that
can be loaded into the vehicle. If the vehicle is
used to tow a trailer, the trailer tongue weight
must be included as part of the cargo load.
This information is located on the Tire and
Loading Information label.

WARNING
Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts on
your vehicle can break, or it can
change the way your vehicle handles.
This could result in loss of control
and cause personal injury.
Overloading not only could shorten
the life of your vehicle and the tires,
but also could lead to unsafe vehicle
handling and long braking distance.
This could cause a premature tire
malfunction, which could result in a
serious accident and personal injury.
Malfunctions caused by overloading
are not covered by your warranty.Roadster model:
Do not tow a trailer with your vehicle.
Coupe model:
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer places additional
loads on your vehicle’s engine, drive train, steer-
ing, braking and other systems.
ANISSAN Trailer Towing Guide(US only) is
available from a NISSAN dealer. This guide
includes information on trailer towing ability and
the special equipment required for proper tow-
ing.
MAXIMUM LOAD LIMITS
Maximum trailer loadsNever allow the total trailer load to exceed 1,000
lb(454 kg). The total trailer load equals trailer
weight plus its cargo weight. Towing loads
greater than 1,000 lb(454 kg) or using improper
towing equipment could adversely affect vehicle
handling, braking and performance.
The ability of your vehicle to tow a trailer is not
only related to the maximum trailer loads, but
also the places you plan to tow. Tow weights
appropriate for level highway driving may have to
be reduced on very steep grades or in low
traction situations (for example, on slippery boat
ramps).
WARNING
Vehicle damage resulting from im-
proper towing procedures are not cov-
ered by NISSAN warranties. A NISSAN
Trailer Towing Guide (U.S. only) contain-
ing information on trailer towing ability
and the special equipment required may
be obtained from a NISSAN dealer.

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 pressuresWhen 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 tipsBe 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
