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
vehicle to another country, state, province
or district, it may be necessary to modify
the vehicle to meet local laws and regula-
tions.
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 registered, its modifications, trans-
portation, and registration are the respon-
sibility of the user. INFINITI is not
responsible for any inconvenience that
may result.

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 sepa-
rately to determine axle loads. In-
dividual 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 ratings are given on the
vehicle certification label. If weight
ratings are exceeded, move or re-
move items to bring all weights
below the ratings. GUID-BC9945CE-0C0A-468B-8072-EAC4EDA8B7B5
Your vehicle was designed to be used to
carry passengers and cargo. INFINITI does
not recommend trailer towing, because it
places additional 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
information 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 GUID-A4A9B27A-245D-4579-9712-944464AA5082
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, al-
ways tow forward, never backward.
. DO NOT tow any automatic transmission
vehicle with all four wheels on the
ground (flat towing). Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
. DO NOT tow an All-Wheel Drive (AWD)
vehicle with any of the wheels on the
ground. Doing so may cause serious and
expensive damage to the powertrain.
. For emergency towing procedures refer
to “ Towing recommended by INFINITI ”
(P.6-12) of this manual.

vehicle ’ s drive wheels. Always follow the
dolly manufacturer ’ s recommendations
when using their product.
Manual transmission GUID-B30ED557-E6C5-4E25-B21C-5F9B6B9B165D
. Always tow with the manual transmis-
sion in Neutral.
. Your vehicle speed should never exceed
70 MPH (112 km/h) when flat towing
your vehicle.
. 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 damage to the
transmission ’ s internal parts. GUID-3E088555-DC3D-4483-A05A-8DA986F1D29D
DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where applic-
able on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEAR GUID-499F0B52-9319-4A2F-9811-B95040CBA836
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course. For
example, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate. TRACTION AA, A, B AND C GUID-06FD06F1-0BA4-4FE2-98C0-CCD1E9E9D435
The traction grades, from highest to low-
est, are AA, A, B and C. Those grades
represent the tire ’ s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.
WARNING The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C GUID-D08B43D7-C76A-4659-BF4F-9C199B188B10
The temperature grades A (the highest), B,
and C, representing the tire ’ s resistance to
the generation of heat and its ability to
dissipate heat when tested under con-
trolled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to suddenUNIFORM TIRE QUALITY GRADING

A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dynam-
ometers 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 trans-
mission 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 emission 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/mainte-
nance test readiness condition. 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 ” .
Contact an INFINITI retailer to set the
“ ready condition ” or to prepare the vehicle
for testing. GUID-9C3875F5-7E59-4991-892A-95438AAA2114
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 performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems 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 passen-
ger safety belts were buckled/fas-
tened;
. 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.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle only
if a nontrivial crash situation occurs; no
data are recorded by the EDR under normal
driving conditions and no personal data
