2012 INFINITI G-COUPE four wheel drive

specified by INFINITI could affect the
proper operation of the TPMS.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.
All season tires
INFINITI specifies all season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than All Season tires and
may be more appropriate in some areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating M&S on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, INFINITI recommends the
use of SNOW tires or ALL SEASON tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load
rating to the original equipment tires. If
you do not, it can adversely affect the
safety and handling of your vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and
may not match the potential maximum
vehicle speed. Never exceed the maximum
speed rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires. Skid and traction capabilities of
studded snow tires, on wet or dry surfaces,
may be poorer than that of non-studded
snow tires.
TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’
s suggestions. Use only SAE
Class S chains. Class“S”chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the
tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling

All-Wheel Drive (AWD) models
CAUTION
.Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer case
and differential gears.
. ONLY use spare tires specified for the
AWD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
construction and tread pattern. The tire
pressure and wheel alignment should also
be checked and corrected as necessary.
Contact an INFINITI retailer.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required. Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to
“Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire)
Observe the following precautions if the T-
type spare tire must be used, otherwise
your vehicle could be damaged or involved
in an accident.
WARNING
. The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage. .
Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
. Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire at
60 psi (420 kPa, 4.2 bar). Always keep
the pressure of the full size spare tire (if
so equipped) at the recommended pres-
sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “Tire and Loading Informa-
tion label” in the index of this manual.
. With the TEMPORARY USE ONLY spare
tire installed do not drive your vehicle at
speeds faster than 50 MPH (80 km/h).
. When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
spare tire should be used on the front
wheels and original tire used on the rear
wheels (drive wheels). Use tire chains
only on the two rear original tires.
. Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than
the standard tire. Replace the spare tire
as soon as the tread wear indicators

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 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.
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
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.

All-Wheel Drive (AWD) models:
