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 cruising
speed through the toll and avoid stop-
ping 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 ef-
fectively circulate the engine oil before
driving.
• Your vehicle will reach its ideal operat- ing 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
possible.
• When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. • Keep your engine tuned up.
• Follow the recommended scheduled
maintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire
wear and lowers fuel economy.
• Keep the wheels in correct alignment. Im- proper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, see “Rec-
ommended fluids/lubricants and capaci-
ties” (P. 10-2).

NOTE:
NISSAN does not advocate the use of
non-OEM approved af termarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the af termar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, see “Recom-
mended fluids/lubricants and capaci-
ties” (P. 10-2).
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belts*:Check engine drive belts for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belts.
Engine air filter: Replace at specified inter-
vals. When driving for prolonged periods in
dusty conditions, check/replace the filter
more frequently.
Engine coolant*: Replace coolant at the
specified interval. When adding or replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
or equivalent with the proper mixture. (For additional information on the proper mix-
ture for your area, see “Engine cooling sys-
tem” (P. 8-5.)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine oil and oil filter:
Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity, see
“Recommended fluids/lubricants and ca-
pacities” (P. 10-2).
Fuel lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing,
cracks, deterioration, and signs of leaking.
Replace any deteriorated or damaged
parts immediately. Brake pads and rotors:
Check for wear, de-
terioration and fluid leaks. Replace any dete-
riorated or damaged parts immediately.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary.
In-cabin microfilter: Replace at specified
intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently.
Steering gear and linkage, axle and sus-
pension parts, drive shaf t boots: Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently.
Tire rotation: Rotate tires at the specified
interval shown in the maintenance sched-
ule. When rotating tires, check for damage
and uneven wear. Replace if necessary.
Transmission fluid/oil: Visually inspect for
signs of leakage at specified intervals.
If using a car-top carrier, or driving on rough
or muddy roads, replace the CVT fluid every
60,000 miles (96,000 km) or request the
dealer to inspect the fluid deterioration data
using a CONSULT. If the deterioration data is
more than 210000, replace the CVT fluid.

ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure
satisfactory engine life and performance.
For additional information, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2). NISSAN recommends the use of an
energy conserving oil in order to improve
fuel economy.Select only engine oils that meet the
American Petroleum Institute (API) certifi-
cation or International Lubricant Standard-
ization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
on the front of the container. Oils which do
not have the specified quality label should
not be used as they could cause engine
damage.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or
has been previously used should not be
used.
Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of
this, it is important to select the engine oil
viscosity based on the temperatures at
which the vehicle will be operated before
the next oil change. Choosing an oil viscos-
ity other than that recommended could
cause serious engine damage.
Selecting the correct oil filter
Your new NISSAN vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN oil filter or
its equivalent for the reason described in
“Change intervals.”
LTI2051
10-6Technical and consumer information

Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Using en-
gine oil and filters that are not of the speci-
fied quality, or exceeding recommended oil
and filter change intervals could reduce
engine life. Damage to the engine caused
by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is
not covered by the NISSAN New Vehicle
Limited Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter
change intervals depend upon how you
use your vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at coldoutside temperatures
• driving in dusty conditions
• extensive idling
• stop and go commuting
For additional information, see “Mainte-
nance and schedules” (P. 9-2).
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your
NISSAN vehicle must be charged with the
refrigerant HFO-1234yf (R-1234yf ) and
Genuine NISSAN A/C System Oil PAG
Type: ND-OIL12 or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
may cause severe damage to the air
conditioning system and may require
the replacement of all air conditioner
system components.
The refrigerant HFO-1234yf (R-1234yf ) in
your NISSAN vehicle does not harm the
earth's ozone layer. Although this refriger-
ant does not affect the earth's atmo-
sphere, certain government regulations re-
quire the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. A NISSAN dealer has
the trained technicians and equipment
needed to recover and recycle your air con-
ditioner system refrigerant. It is recommended that you visit a NISSAN
dealer when servicing your air conditioner
system.
