2011 INFINITI G-CONVERTIBLE technical specifications

●Check your local regulations.
(Perform steps 4 to 7 only when the engine
oil filter change is needed.)
4. Loosen the oil filter2with an oil filter
wrench. Remove the oil filter by turning it
by hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old rubber gasket re-
maining on the mounting surface of the engine.
Failure to do so could lead to engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight 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 the engine with the recommended oil through the oil filler opening, 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 clips out.
b. Hold the engine undercover into position.
c. Insert the clips through the undercover into the holes in the frame, then push the
center of the clips in to lock the clips in
place.
d. Install the bolts that hold the undercover 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 the reach of
children.
8-10Maintenance and do-it-yourself

●The original tires have built-in tread
wear indicators. When wear indicators
are visible, the tire(s) should be
replaced.
●Tires degrade with age and use. Have
tires, including the spare, over 6 years
old checked by a qualified technician,
because some tire damage may not be
obvious. Replace the tires as necessary
to prevent tire failure and possible per-
sonal injury.
●Improper service of the spare tire may
result in serious personal injury. If it is
necessary to repair the spare tire, con-
tact an INFINITI retailer.
●For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity as originally equipped. (See “SPECIFICATIONS”
in the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.)
WARNING
●
The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or ra-
dial), or tread patterns can adversely affect
the ride, braking, handling, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration, head-
light aim and bumper height. Some of these
effects may lead to accidents and could re-
sult in serious personal injury.
●
If the wheels are changed for any reason, al-
ways replace with wheels which have the
same off-set dimension. Wheels of a different
off-set could cause premature tire wear, de-
grade vehicle handling characteristics and/or
interference with the brake discs/drums. Such
interference can lead to decreased braking ef-
ficiency and/or early brake pad/shoe wear.
See “WHEELS AND TIRES” in the “9. Technical
and consumer information” section of this
manual for wheel off-set dimensions.
● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● Do not install a damaged or deformed wheel
or tire even if it has been repaired. Such
wheels or tires could have structural damage
and could fail without warning.
● The use of retread tire is not recommended.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.

CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS
9-2Technical and consumer information

FUEL RECOMMENDATION
VQ37VHR engine
Use unleaded premium gasoline with an octane
rating of at least 91 AKI (Anti-Knock Index)
number (Research octane number 96).
If premium gasoline is not available, unleaded
regular gasoline with an octane rating of 87 AKI
number (Research octane number 91) may be
temporarily used, but only under the following
precautions:
●Have the fuel tank filled only partially with
unleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as pos-
sible.
● Avoid full throttle driving and abrupt accel-
eration.
However, for maximum vehicle performance, the
use of unleaded premium gasoline is recom-
mended.
CAUTION
● Using a fuel other than that specified could
adversely affect the emission control sys-
tem, and may also affect warranty coverage.
● Under no circumstances should a leaded
gasoline be used, because this will damage
the three-way catalyst. ●
Do not use E-85 fuel in your vehicle. Your
vehicle is not designed to run on E-85 fuel.
Using E-85 fuel can damage the fuel system
components and is not covered by the
INFINITI vehicle limited warranty.
Gasoline specifications
INFINITI recommends using gasoline that meets
the World-Wide Fuel Charter (WWFC) specifica-
tions where it is available. Many of the automo-
bile manufacturers developed this specification
to improve emission system and vehicle perfor-
mance. Ask your service station manager if the
gasoline meets the World-Wide Fuel Charter
(WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing refor-
mulated gasolines. These gasolines are spe-
cially designed to reduce vehicle emissions.
INFINITI supports efforts towards cleaner air
and suggests that you use reformulated gaso-
line when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and metha-
nol with or without advertising their presence.
INFINITI does not recommend the use of fuels of which the oxygenate content and the fuel com-
patibility for your INFINITI cannot be readily
determined. If in doubt, ask your service station
manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage of
such fuels may cause vehicle performance prob-
lems and/or fuel system damage.
●
The fuel should be unleaded and have an oc-
tane rating no lower than that recommended
for unleaded gasoline.
● If an oxygenate-blend, excepting a methanol
blend, is used, it should contain no more than
10% oxygenate. (MTBE may, however, be
added up to 15%.)
● If a methanol blend is used, it should contain
no more than 5% methanol (methyl alcohol,
wood alcohol). It should also contain a suit-
able amount of appropriate cosolvents and
corrosion inhibitors. If not properly formu-
lated with appropriate cosolvents and corro-
sion inhibitors, such methanol blends may
cause fuel system damage and/or vehicle
performance problems. At this time, suffi-
cient data is not available to ensure that all
methanol blends are suitable for use in
INFINITI vehicles.

you
should first find out if the fuel available is
suitable for your vehicle’s engine.
Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline.
Therefore, avoid taking your vehicle to areas
where appropriate fuel is not available.
When transferring the registration of your ve-
hicle to another country, state, province or dis-
trict, it may be necessary to modify the vehicle
to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into another
country, state, province or district and regis-
tered, its modifications, transportation, and reg-
istration are the responsibility of the user.
INFINITI is not responsible for any inconvenience
that may result.
