∙ Your vehicle will reach its ideal oper-ating temperature more quickly
while driving versus idling.
10. Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Recommended fluids/lubricants and
capacities” in the “Technical and con-
sumer information” section of this
manual.

this section. Inclement weather may
affect the function of the sonar sys-
tem; this may include reduced perfor-
mance or a false activation.
∙ The system is deactivated at speeds above 6 mph (10 km/h). It is reacti-
vated at lower speeds.
∙ Inclement weather or ultrasonic sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system; this may
include reduced performance or a
false activation.
∙ The system is not designed to prevent contact with small or moving objects.
Always move slowly. The system will
not detect small objects below the
bumper or on the ground.
∙ The system may not detect the fol- lowing objects: fluff y objects such as
snow, cloth, cotton, glass-wool, etc.;
thin objects such as rope, wire and
chain, etc.; or wedge-shaped objects. ∙ The system may not detect objects at

∙ Use only Genuine NISSAN floor mats,or equivalent floor mats, that are spe-
cifically designed for use in your ve-
hicle model and model year.
∙ Properly position the mats in the floorwell using the floor mat position-
ing hook. For additional information,
refer to "Floor mat installation" in this
section.
∙ Make sure the floor mat does not in- terfere with pedal operation.
∙ Periodically check the floor mats to make sure they are properly installed.
∙ Af ter cleaning the vehicle interior, check the floor mats to make sure
they are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular clean-
ing and replaced if they become exces-
sively worn.
Floor mat installation
Your vehicle is equipped with floor mat po-
sitioning hook(s). The number and shape of the floor mat positioning hooks for each
seating position varies depending on the
vehicle.
When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the shif t lever in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t
lever in the P (Park) position and with
the parking brake applied, fully apply
and release all pedals. The floor mat
must not interfere with pedal opera-
tion or prevent the pedal from return-
ing to its normal position.
It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle. The illustration shows the location of the
floor mat positioning hooks.
SEAT BELTS
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely in the shade before using them. For
additional information, refer to “Seat belt
maintenance” in the “Safety—Seats, seat
belts and supplemental restraint system”
section of this manual.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙ Park the vehicle on a level surface, ap-ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
∙ Be sure the ignition key is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine run- ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even
if the ignition key is in the OFF position
and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before work-
ing near the fan.
∙ If you must run the engine in an en- closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ On gasoline engine models, the fuel filter or fuel lines should be serviced. It
is recommended that you visit a
NISSAN dealer for this service because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
∙ Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ∙
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
∙ Never leave the engine or the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
