engine INFINITI G-COUPE 2010 Owners Manual

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.
If any undesirable driveability problems such as
engine stalling or hard hot starting are experi-
9-4Technical and consumer information

enced after using oxygenate-blend fuels, imme-
diately change to a non-oxygenate fuel or a fuel
with a low blend of MTBE.
Take care not to spill gasoline during refueling.
Gasoline containing oxygenates can cause paint
damage.
E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed on
level roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.
CAUTION
●Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
● U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure sat-
isfactory engine life and performance, see “CA-
PACITIES AND RECOMMENDED
FUEL/LUBRICANTS” earlier in this section.
INFINITI 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) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE viscos-
ity standard. These oils have the API certifica-
tion 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
INFINITI 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 impor-
tant that the engine oil viscosity be selected
based on the temperatures at which the vehicle
will be operated before the next oil change.
Choosing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When replac-
ing, use the genuine oil filter or its equivalent
for the reason described in change intervals.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than
the specified quality, or oil and filter change
intervals longer than recommended could re-
duce engine life. Damage to engines caused by
improper maintenance or use of incorrect oil
and filter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warranties.
Your engine was filled with a high quality
engine oil when it was built. You do not have to

If you plan to travel in another country, 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.

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is loaded,
drive to a scale and weigh the front and
the rear wheels separately to determine
axle loads. Individual axle loads should
not exceed either of the gross axle
weight ratings (GAWR). The total of the
axle loads should not exceed the gross
vehicle weight rating (GVWR). These rat-
ings are given on the vehicle certifica-
tion label. If weight ratings are ex-
ceeded, move or remove items to bring
all weights below the ratings.
Your vehicle was designed to be used to carry
passengers and cargo. INFINITI does not recom-
mend trailer towing, because it places addi-
tional loads on your vehicle’s engine, drivetrain,
steering, braking, and other systems.
An INFINITI Towing Guide (U.S. only) is available
on the website at
www.InfinitiUSA.com. This guide includes infor-
mation on trailer towing capability and the
special equipment required for proper towing.
CAUTION
Vehicle damage resulting from towing a trailer
is not covered by INFINITI warranties.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a
vehicle behind a recreational vehicle, such as a
motor home.
CAUTION
●Failure to follow these guidelines can result
in severe transmission damage.
● Whenever flat towing your vehicle, always
tow forward, never backward. ●
DO NOT tow any automatic transmission ve-
hicle with all four wheels on the ground (flat
towing). Doing so WILL DAMAGE internal
transmission parts due to lack of transmis-
sion lubrication.
● For emergency towing procedures refer to
“TOWING RECOMMENDED BY INFINITI” in the
“6. In case of emergency” section of this
manual.
Automatic transmission
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST be placed under the towed vehicle’s drive
wheels. Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
Manual transmission
● Always tow with the manual transmission in
Neutral.
● Your vehicle speed should never exceed 70
MPH (112 km/h) when flat towing your ve-
hicle.
● After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause dam-
age to the transmission’s internal parts.
TOWING A TRAILER
Technical and consumer information9-21

04/21/10—debbie


A vehicle equipped with All-Wheel Drive (AWD)
should never be tested using a two wheel
dynamometer (such as the dynamometers used
by some states for emissions testing), or similar
equipment. Make sure you inform test facility
personnel that your vehicle is equipped with
AWD before it is placed on a dynamometer.
Using the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Push the ignition switch to the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds, the I/Mtest condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
If the MIL indicates the vehicle is in a “not
ready” condition, drive the vehicle through the
following pattern to set the vehicle to the
“ready condition”. If you cannot or do not want
to perform the driving pattern, an INFINITI re-
tailer can conduct it for you.
WARNING
Always drive the vehicle in a safe and prudent
manner according to traffic conditions and
obey all traffic laws.
1. Start the engine. Allow the engine to idle
until the engine coolant temperature
gauge needle points between the C and H
(normal operating temperature).
2. Accelerate the vehicle to 55 MPH (88 km/h), then quickly release the accelera-
tor pedal completely and keep it released
for at least 10 seconds.
3. Quickly depress the accelerator pedal for a moment, then drive the vehicle at a
speed of 53 to 60 MPH (86 to 96 km/h) for
at least 9 minutes.
4. Stop the vehicle. Leave the engine run- ning. 5. Accelerate the vehicle to 55 MPH (88
km/h) and maintain the speed for 2 min-
utes.
6. Repeat steps 4 and 5 at least 10 times.
7. Quickly release the accelerator pedal completely and keep it released for at
least for 1 minute. Maintain the speed for
at least 5 minutes.
8. Stop the vehicle. Place the automatic transmission selector lever in the P (Park)
or N (Neutral) position or the manual
transmission shift lever in the N (Neutral)
position.
9. Turn the engine off.
10. Start the engine and allow the engine to idle for at least 2 hours.
11. Place the ignition switch to the OFF posi- tion and leave the vehicle for at least 90
minutes.
If step 1 through 7 is interrupted, repeat the
preceding step. Any safe driving mode is ac-
ceptable between steps. Do not stop the engine
until step 7 is completed.
