2011 INFINITI EX fuel cap

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
●Park the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. Move
the selector lever to P (Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position.
● If you must work with the engine running,
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.
● If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
● Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery.
● Your vehicle is equipped with an automatic
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 discon-
nect the negative battery cable before work-
ing near the fan.
● On gasoline engine models, the fuel filter or
fuel lines should be serviced by an INFINITI
retailer 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 direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.

7. Screw in the oil filter clockwise until aslight resistance is felt, then tighten ad-
ditionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(14.7 to 20.5 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section for drain and
refill capacity. The drain and refill capacity
depends on the oil temperature and drain time.
Use these specifications for reference only.
Always use the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover into positionas the following steps.
a. Pull the center of the small plastic clip out.
b. Hold the engine undercover into position.
c. Insert the clip through the undercover into the hole in the frame, then push the
center of the clip in to lock the clip in
place.
d. Install the other bolts that hold the un- dercover in place. Be careful not to strip
the bolts or over-tighten them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.
WARNING
●Prolonged and repeated contact with used
engine oil may cause skin cancer.
● Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
● Keep used engine oil out of reach of children.

For further brake fluid specification information,
see “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section of this manual.
WARNING
●Use only new fluid from a sealed container.
Old, inferior or contaminated fluid may dam-
age the brake system. The use of improper
fluids can damage the brake system and af-
fect the vehicle’s stopping ability.
● Be sure to clean the filler cap before
removing.
● Brake fluid is poisonous and should be
stored carefully in marked containers out of
the reach of children.
CAUTION
Do not spill the fluid on painted surfaces. This
will damage the paint. If fluid is spilled, wash
the surface with water. Check the fluid level in the reservoir. If the fluid
is below the MIN line
2or the brake warning
light comes on, add Genuine NISSAN Super
Heavy Duty Brake Fluid or equivalent DOT 3fluid
up to the MAX line
1. If fluid must be added
frequently, the system should be checked by an
INFINITI retailer.
WARNING
Antifreeze is poisonous and should be stored
carefully in marked containers out of the reach
of children.
Fill the window washer fluid reservoir periodi-
cally. Add window washer fluid when the low
window washer fluid warning light comes on.
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window
washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a wind-
