CERTIFICATION LABEL
The Federal/Canadian Motor Vehicle Safety
Standard (F.M.V.S.S./C.M.V.S.S.) certifica-
tion label is affixed as shown. This label con-
tains valuable vehicle information, such as:
(GVWR), (GAWR), month and year of manu-
facture, (VIN), etc. Review it carefully.
EMISSION CONTROL
INFORMATION LABEL
The emission control information label is at-
tached to the underside of the hood as
shown.

Technical and consumer information10-11

WARNING
A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dyna-
mometers used by some states for emis-
sions testing), or similar equipment. Make
sure you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Us-
ing the wrong test equipment may result in
transmission damage or unexpected ve-
hicle movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready con-
dition” for an Inspection/Maintenance (I/M)
test of the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving pat-
terns. 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. Be-
fore taking the I/M test, check the vehicle's
inspection/maintenance test readiness con-
dition. Place the ignition switch in 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/M test condition is “not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”. It is
recommended that you visit an INFINITI re-
tailer to set the “ready condition” or to pre-
pare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle's systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems for a short period of time, typically 30
seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
• Sounds are not recorded.

FUEL RECOMMENDATION:
Use unleaded premium gasoline with an oc-
tane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
If unleaded premium gasoline is not available,
unleaded regular gasoline with an octane rat-
ing of at least 87 AKI number (Research oc-
tane number 91) may be temporarily used,
but only under the following precautions:
• Have the fuel tank filled only partially withunleaded regular gasoline, and fill up with
unleaded premium gasoline as soon as
possible.
• Avoid full throttle driving and abrupt acceleration.
Use unleaded premium gasoline for maxi-
mum vehicle performance.
CAUTION
• Using a fuel other than that specified
could adversely affect the emission con-
trol system, and may also affect the war-
ranty coverage.
• Under no circumstances should a leaded
gasoline be used, because this will dam-
age the three-way catalyst. •
Do not use a fuel containing more than
15% ethanol in your vehicle. Your vehicle
is not designed to run on a fuel contain-
ing more than 15% ethanol. Using a fuel
containing more than 15% ethanol in a
vehicle not specifically designed for a
fuel containing more than 15% ethanol
can adversely affect the emission control
devices and systems of the vehicle. Dam-
age caused by such fuel is not covered by
the INFINITI New Vehicle Limited
Warranty.
• Do not use fuel that contains the octane
booster methylcyclopentadienyl man-
ganese tricarbonyl (MMT). Using fuel
containing MMT may adversely affect
vehicle performance and vehicle emis-
sions. Not all fuel dispensers are labeled
to indicate MMT content, so you may
have to consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of MMT
in reformulated gasoline.
• U.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and black
label with the common abbreviation or
the appropriate percentage for that
region. For additional information, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2).
RECOMMENDED ENGINE OIL:
See “Recommended fluids/lubricants and ca-
pacities” (P. 10-2).
COLD TIRE PRESSURE:
For additional information, see “Tire and
Loading Information label” (P. 8-29).
The label is typically located on the driver side
center pillar or on the driver's door. For addi-
tional information, see “Wheels and tires”
(P. 8-27).
RECOMMENDED NEW VEHICLE
BREAK-IN PROCEDURE:
During the first 1,200 miles (2,000 km) of
vehicle use, follow the break-in procedure
recommendations for the future reliability
and economy of your new vehicle. For addi-
tional information, see “Break-in schedule”
(P. 5-131). Failure to follow these recom-
mendations may result in vehicle damage or
shortened engine life.
