5.Use Cruise Control
∙ Using cruise control during highway driving helps maintain a steady
speed.
∙ Cruise control is particularly effective in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
∙ Utilize a map or navigation system to determine the best route to save
time.
7. Avoid Idling
∙ Shutting off your engine when safe for stops exceeding 30–60 seconds
saves fuel and reduces emissions.
8. Buy an Automated Pass for Toll
Roads
∙ Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and avoid
stopping and starting. 9.
Winter Warm Up
∙ Limit idling time to minimize impact to fuel economy.
∙ Vehicles typically need no more than 30 seconds of idling at start-up to
effectively circulate the engine oil be-
fore driving.
∙ 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.
∙ For vehicles equipped with
, use
4H or 4L position only when necessary.
4-wheel drive operation lowers fuel
economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.

Installing the spare tire
The spare tire is designed for emergency
use. For additional information, refer to
“Wheels and tires” in the “Do-it-yourself ”
section of this manual.1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence illustrated (
1,2,3,4,5,6)
until they are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence illus-
trated (
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 vehicle has been driven for 620 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: 98 f t-lb (133 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 inter-
val.
Adjust tire pressure to the COLD pres-
sure.
COLD pressure: Af ter vehicle has been
parked for 3 hours or more or driven less
than 1 mile (1.6 km).
COLD tire pressures are shown on the
Tire and Loading Information label lo-
cated in the driver’s door opening.
5. Securely store the jacking equipment in the vehicle and the flat tire under the
vehicle. For additional information
about storing the flat tire, refer to “Get-
ting the spare tire and tools” in this sec-
tion.

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. For manual trans-
mission models, move the shif t lever
to N (Neutral). For Automatic Trans-
mission (A/T) move the shif t lever 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.
∙ 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
because the fuel lines are under high
pressure even when the engine is off.
It is recommended that you visit a
NISSAN dealer for this service.
CAUTION
∙ Do not work under the hood while theengine 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.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.

∙ Under no circumstances should aleaded gasoline be used, because this
will damage the three-way catalyst.
∙ Do not use E-15 or E-85 fuel in your vehicle. Your vehicle is not designed to
run on E-15 or E-85 fuel. Using E-15 or
E-85 fuel in a vehicle not specifically
designed for E-15 or E-85 fuel can ad-
versely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the NISSAN New Vehicle
Limited Warranty.
∙ Do not use fuel that contains the oc- tane booster methylcyclopentadienyl
manganese tricarbonyl (MMT). Using
fuel containing MMT may adversely
affect vehicle performance and ve-
hicle emissions. Not all fuel dispens-
ers are labeled to indicate MMT con-
tent, so you may have to consult your
gasoline retailer for more details.
Note that Federal and California laws
prohibit the use of MMT in reformu-
lated gasoline. ∙ U.S. government regulations require
ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation or the appropriate percentage
for that region.
For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in the “Technical and consumer informa-
tion” section of this manual.
FLEXIBLE FUEL VEHICLE (FFV)
FUEL RECOMMENDATION (if so
equipped):
If your vehicle is equipped as a Flexible Fuel
Vehicle (FFV) your vehicle is designed to
use (E-85) Fuel Ethanol, “Regular” unleaded
regular gasoline or any percentage of the
two fuels combined.
CAUTION
∙ Using a fuel other than that specified could adversely affect the emission
control system, and may also affect
the warranty coverage.
∙ Under no circumstances should a leaded gasoline be used, because this
will damage the three-way catalyst. For additional information, refer to “Recom-
mended fluids/lubricants and capacities”
in the “Technical and consumer informa-
tion” section of this manual.
ENGINE OIL RECOMMENDATION:
QR25DE engine models:
• Genuine “Nissan Motor Oil 5W-30 SN”
VQ40DE engine models:
• Genuine “Nissan Motor Oil Ester 5W-30 SN”
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
COLD TIRE PRESSURE:
For additional information, refer to “Tire and
Loading Information label” in the “Technical
and consumer information” section of this
manual.
The label is typically located on the driver
side center pillar or on the driver’s door. For
additional information, refer to “Wheels and
tires” in the “Do-it-yourself ” section of this
manual.
