The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level.See “Engine
oil” in the “8. Maintenance and do-it-yourself”
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Turn off the engine as
soon as it is safe to do so.
Low tire pressure warning light
(if so equipped)
The light comes on for about 1 second when the
ignition switch is turned ON, and then it turns off.
NISSAN’s low tire pressure warning system is a
tire pressure monitoring system. It monitors tire
pressure of all tires except the spare. When the
tire pressure monitoring system warning light is
lit, one or more of your tires is significantly
under-inflated. You should stop and check your
tires as soon as possible, and inflate them to theproper pressure as indicated on the vehicle’s tire
information placard. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire malfunction. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stop-
ping ability. Each tire, including the spare, should
be checked monthly when cold and set to the
recommended inflation pressure as specified in
the vehicle placard and Owner’s Manual.
The recommended inflation pressure may also
be found on the Tire and Loading Information
label.
If the vehicle is being driven with very low tire
pressure (lower than 28 psi), the light will illumi-
nate and the chime will sound for about 10
seconds.
For additional information, see “Low tire pres-
sure warning system” in the “5. Starting and
driving” section and “Flat tire” in the “6. In case
of emergency” section. You can check the tire
pressure of all 4 tires on the trip computer
display. See “Trip computer” earlier in this sec-
tion.
WARNING

If the light does not come on with theignition switch turned ON, have the
vehicle checked by a NISSAN dealer
as soon as possible.

If the light comes on while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location
and stop the vehicle as soon as pos-
sible. Serious vehicle damage could
occur and may lead to an accident
and could result in serious personal
injury. Check the pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light OFF. If the light
still comes on while driving after ad-
justing the tire pressure, a tire may
be flat. If you have a flat tire, replace
it with a spare tire as soon as pos-
sible.

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

The exhaust system and body should
be inspected by a qualified mechanic
whenever:
•The vehicle is raised for service.
•You suspect that exhaust fumes
are entering into the passenger
compartment.
•You notice a change in the sound
of the exhaust system.
•You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.THREE WAY CATALYSTThe three way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the converter are burned at high tem-
peratures to help reduce pollutants.
WARNING

The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-mals or flammable materials away
from the exhaust system compo-
nents.

Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION

Do not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst’s ability
to help reduce exhaust pollutants.

Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by a NISSAN
dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.

Do not race the engine while warm-
ing it up.

Do not push or tow your vehicle to
start the engine.
LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)The low tire pressure warning system displays
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.
Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and the
outside temperature. Low outside temperature
can lower the temperature of the air inside the
tire which can cause a lower tire inflation pres-
sure. This may cause the low tire pressure
warning light to illuminate.
If the warning light illuminates in low ambient
temperatures as described above, check the tire
pressure for all four tires. Adjust the tire pressure
to the recommended COLD tire pressure shown

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).

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.

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 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.

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

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
