shown.

Other tire-related terminology:

In addition to the many terms that are
defined throughout this section, In-
tended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears manu-
facturer, brand and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall of the tire, or (2) the outward
facing sidewall of an asymmetrical
tire that has a particular side that
must always face outward when
mounted on a vehicle.

TYPES OF TIRES

WARNING

.

When changing or replacing tires, be
sure all four tires are of the same type
(Example: Summer, All Season or
Snow) and construction. An INFINITI
retailer may be able to help you with
information about tire type, size,
speed rating and availability.

.

Replacement tires may have a lower
speed rating than the factory
equipped tires, and may not match
the potential maximum vehicle speed.
Never exceed the maximum speed
rating of the tire.

.

Replacing tires with those not origin-
ally 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
Information” (Canada) in the War-
ranty Information Booklet.

All season tires

INFINITI specifies all season tires on some
models to provide good performance all

Do-it-yourself

Do-it-yourself

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. Sum-
mer 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 prohibit 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 accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions.

Use only SAE Class S chains.

Class

“S” chains are used on vehicles with re-
stricted 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
accommodate 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
recommended by the tire chain manufac-
turer 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
and performance may be adversely affected.

Tire chains must be installed only on the
rear wheels and not on the front wheels.

Never install tire chains on the full-size
temporary use only spare tire (if so
equipped).
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

SDI1662

CHANGING WHEELS AND TIRES

Tire rotation

INFINITI recommends rotating the
tires every 7,500 miles (12,000 km).
(See “Flat tire” (P.6-3) for tire repla-
cing procedures.)

As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Wheel nut tightening torque:

98 ft-lb (133 N·m)

The wheel nuts must be kept tigh-

tened to the specification at all times.
It is recommended that wheel nuts be
tightened to the specification at each
tire rotation interval.

WARNING

.

After rotating the tires, check
and adjust the tire pressure.

.

Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).

.

Do not include the full-size
temporary use only spare tire
(if so equipped) in the tire
rotation.

.

For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Tire wear and damage

WARNING

.

Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.

.

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 personal injury.

.

Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
c o m m e n d e d y o u v i s i t a n
INFINITI retailer for this ser-
vice.

.

For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information 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 “Speci-
fications” (P.10-8) for recommended types
and sizes of tires and wheels.)

WARNING

.

The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted or radial), or
tread patterns can adversely affect
the ride, braking, handling, ground
clearance, body-to-tire clearance,
tire chain clearance, speedometer
calibration, headlight aim and bum-
per height. Some of these effects may
lead to accidents and could result in
serious personal injury.

.

For Two-Wheel Drive (2WD) models,
if your vehicle was originally
equipped with 4 tires that were the
same size and you are only replacing
2 of the 4 tires, install the new tires
on the rear axle. Placing new tires on
the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and
personal injury.

.

If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
9) for wheel off-set dimensions.

.

Since the spare tire is not equipped
with the TPMS, 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 remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.

.

Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.

.

The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.

.

When replacing the TPMS sensor, the
ID registration may be required. It is

recommended you visit an INFINITI
retailer for ID registration.

.

Do not use a valve stem cap that is
not specified by INFINITI. The valve
stem cap may become stuck.

.

Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of pres-
sure.

.

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 recom-
mended.

.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-
ranty Information Booklet.

Four-Wheel Drive (4WD) 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 differ-
ence between tires on the front and
rear axles which will cause excessive
tire wear and may damage the trans-
mission, transfer case and differential
gears.

.

ONLY use spare tires specified for
the 4WD model.

If excessive tire wear is found, it is recom-
mended that all four tires be replaced 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. It is recommended
you visit an INFINITI retailer for this service.

Wheel balance

Unbalanced wheels may affect vehicle hand-
ling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.

Wheel balance service should be performed
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 Booklet.

Care of wheels

See “Cleaning exterior” (P.7-2) for details
about care of the wheels.

Spare tire

Since the spare tire is not equipped with the
TPMS, when a spare tire is mounted (TEM-
PORARY USE ONLY), the TPMS will not
function.

Spare tire (FULL-SIZE TEMPORARY USE
ONLY spare tire) (Applies ONLY to vehicles
equipped with P275/50R22 tires or
P275/60R20 tires):

Observe the following precautions if the full-
size temporary use only spare tire must be
used, otherwise your vehicle could be da-
maged or involved in an accident.

gency use. It should be replaced with
the standard tire at the first oppor-
tunity to avoid possible tire or differ-
ential damage

.

Drive carefully while the spare tire is
installed. Avoid sharp turns and
abrupt braking while driving. The
vehicle driving performance may be
affected when driving on wet or
snow covered roads.

.

When the spare tire is installed, the
following systems may not work
correctly.

— Tire Pressure Monitoring System

(TPMS)

pressure. Always keep the spare tire
inflated to the pressure specification
shown on the Tire and Loading
Information label. For Tire and Load-
ing Information label location, see
“Tire and Loading Information label”
in the index of this manual.

.

With the spare tire installed do not
drive your vehicle at speeds faster
than 70 MPH (112 km/h).

.

When driving on roads covered with
snow or ice, the 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.

.

Do not use the spare tire on other
vehicles.

.

Do not use more than one spare tire
at the same time.

CAUTION

Do not use tire chains on the spare tire.
Tire chains will not fit properly and may
cause damage to the vehicle.

the wipers and washer operate properly and
that the wipers do not streak.

Under the hood and vehicle

The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).

Battery*:

Check the fluid level in each cell. It

should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe condition require frequent
checks of the battery fluid level.

NOTE:

Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:

1.

Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)

2.

Vehicle is not driven regularly and/or
only driven short distances.

In these cases, the battery may need to be
charged to maintain battery health.

Brake fluid level*:

Make sure that the brake

fluid level is between the MAX and MIN lines
on the reservoir.

Engine coolant level*:

Check the coolant

level when the engine is cold.

Engine drive belt*:

Make sure that no belt is

frayed, worn, cracked or oily.

Engine oil level*:

Check the level after

parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.

Exhaust system:

Make sure there are no

loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4) for exhaust gas (carbon
monoxide).)

Fluid leaks:

Check under the vehicle for fuel,

Check

the level when the fluid is cold, with the
engine off. Check the lines for proper
attachment, leaks, cracks, etc.

Radiator and hoses:

Check the front of the

radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.

Underbody:

The underbody is frequently

exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).

Windshield washer fluid*:

Check that there

is adequate fluid in the reservoir.

The following descriptions are provided to
