4. Lower the vehicle slowly until the tiretouches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated
(
1,2,3,4,5,6) . Lower the vehicle
completely.
WARNING
● Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
● Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
● Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque:
Non-XD models: 98 ft-lb (133 N·m) XD models:
131 ft-lb (177 N·m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specifications at each lubrication interval.
Adjust tire pressure to the COLD pressure.
COLD pressure: After vehicle has been
parked for 3 hours or more or driven less
than 1 mi. (1.6 km) .
COLD tire pressures are shown on the Tire
and Loading Information label affixed to
the driver side center pillar.
After adjusting tire pressure to the COLD
tire pressure, the display(if so equipped) of
the tire pressure information may show
higher pressure than the COLD tire pres-
sure after the vehicle has been driven more
than 1 mi. (1.6 km) . This is because the tire
pressure increases as the tire temperature
rises. This does not indicate a system mal-
function. 5. Securely store the flat tire, tools and jacking equipment in the vehicle. For additional in-
formation about storing the flat tire, refer to
the “Getting the spare tire and tools” in this
section.
WARNING
●Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
● The spare tire is designed for emer-
gency use. For additional information,
refer to “Wheels and tires” in the “Do-
it-yourself” section of this manual.

Rear-Wheel Drive models
NISSAN recommends that your vehicle be towed
with the driving (rear) wheels off the ground or
place the vehicle on a flat bed truck as illustrated.
CAUTION
●Never tow automatic transmission
models with the rear wheels on the
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 automatic transmission
models with the front wheels on the
ground or on towing dollies:
– Place the ignition switch in the OFF position and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may cause damage to the
lock mechanism (if so equipped) .
When towing long distances or speeds in excess
of 60 mph (97 km/h), remove the propeller shaft
before towing to prevent damage to the transmis-
sion. It is recommended that you visit a NISSAN
dealer for more information.

When installing Genuine NISSAN floor mats,
follow the installation instructions provided with
the mat and the following:1. 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 interfere with pedal operation. With the ignition in the
OFF position, the selector lever in the P
(Park) position (Automatic Transmission
models) or the shift lever in the N (Neutral)
position (Manual Transmission models) fully
apply and release all pedals. The floor mat
must not interfere with pedal operation or
prevent the pedal from returning to its nor-
mal 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

7-6Appearance and care

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions 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 vehicle
from moving. Move the shift lever to P
(Park)
● Be sure the ignition switch 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 jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
The automatic engine cooling fan (if so
equipped) may come on at any time
without warning, even if the ignition
switch is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative battery
cable before working 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, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● Because the fuel lines on gasoline en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.
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 automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.

shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
●Do not substitute engine antifreeze
coolant for windshield-washer fluid.
This may result in damage to the paint.
● Do not fill the windshield-washer fluid
reservoir with washer fluid concen-
trates at full strength. Some methyl al-
cohol based washer fluid concentrates
may permanently stain the grille if
spilled while filling the windshield-
washer fluid reservoir.
● Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the windshield-washer fluid reser-
voir. Do not use the windshield-washer
fluid reservoir to mix the washer fluid
concentrate and water. ●
If the battery is labeled do not openit is
maintenance free and battery fluid should
not be checked. It is recommended that you
visit a NISSAN dealer or a qualified special-
ist workshop to confirm the battery’s perfor-
mance.

that can lead to potential battery discharge
and potential no-start conditions such as: 1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc.) . 2. Vehicle is not driven regularly and/or only
driven short distances. In these cases, the
battery may need to be charged to maintain
battery health.
WARNING
●Do not expose the battery to flames, an
electrical spark or a cigarette. Hydrogen
gas generated by the battery is explo-
sive. Explosive gases can cause blind-
ness or injury. Do not allow battery fluid
to contact your skin, eyes, fabrics or
painted surfaces. Sulfuric acid can
cause blindness or injury. After touch-
ing a battery or battery cap, do not
touch or rub your eyes. Thoroughly
wash your hands. If the acid contacts
your eyes, skin or clothing, immediately
flush with water for at least 15 minutes
and seek medical attention.
● Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery
which can generate heat, reduce battery
life, and in some cases lead to an
explosion.
● When working on or near a battery, al-
ways wear suitable eye protection and
remove all jewelry.
