Installing the spare tireGUID-003A0190-9B2C-45A9-A542-11B8BA923B48The T-type spare tire is designed for
emergency use. (See specific instructions
under the heading“Wheels and tires” (P.8-
29).)
1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
Check that all the wheel nuts contact
the wheel surface horizontally.
When replacing a front tire, make sure
that the hole in the spare tire wheel is
aligned with the pin on the brake rotor. 3. With the wheel nut wrench, tighten
wheel nuts alternately and evenly in the
sequence as illustrated (
*1,*2,*3,
*4,*5) until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as
illustrated. Lower the vehicle comple-
tely.
WARNING
. Incorrect wheel nuts or improperly tigh-
tened wheel nuts can cause the wheel to
become loose or come off. This could
cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench. Wheel nut tightening torque:
80 ft-lb (108 N·m)
The wheel nuts must be kept tightened
to specifications at all times. It is
recommended that the wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD pressure.
COLD pressure:
After the vehicle has been parked for 3
hours or more or driven less than 1
mile (1.6 km).
COLD tire pressures are shown on the
Tire and Loading Information label
affixed to the driver side center pillar.
5. Securely store the flat tire and jacking equipment in the vehicle.
6. Place the jacking tool case and the trunk floor board over the damaged
tire.
7. Close the trunk.
WARNING
. Always make sure that the spare tire and
jacking equipment are properly secured
In case of emergency6-7

CAUTION
.Never use benzine, thinner, or any
similar material.
. Small dirt particles can be abrasive and
damaging to the leather surfaces and
should be removed promptly. Do not use
saddle soap, car waxes, polishes, oils,
cleaning fluids, solvents, detergents or
ammonia-based cleaners as they may
damage the leather’s natural finish.
. Only use fabric protectors approved by
INFINITI.
. Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERSGUID-59E4BAA1-C864-45BB-9523-2C9768183480Most air fresheners use a solvent that
could affect the vehicle interior. If you use
an air freshener, take the following pre-
cautions:
.Hanging-type air fresheners can cause
permanent discoloration when they
contact vehicle interior surfaces. Place
the air freshener in a location that
allows it to hang free and not contact an interior surface.
. Liquid-type air fresheners typically clip
on the vents. These products can cause
immediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufac-
turer’s instructions before using air fresh-
eners.
FLOOR MATSGUID-CC129FD0-3289-4899-B87E-ABA4B8EC627B
WARNING
To avoid potential pedal interference that
may result in a collision or injury:
. NEVER place a floor mat on top of
another floor mat in the driver front
position.
. Use only genuine NISSAN floor mats
specifically designed for use in your
vehicle model. See your INFINITI retailer
for more information.
. Properly position the mats in the floor-
well using the floor mat positioning aid.
See “Floor mat positioning aid” (P.7-6).
The use of NISSAN floor mats can extend
the life of your vehicle carpet and make it easier to clean the interior. Mats should be
maintained with regular cleaning and
replaced if they become excessively worn.

GUID-058FA41E-D16E-49C1-B0F1-1263C55FFFD2
Selecting the correct oilGUID-9C2E08EF-024B-4ED8-82D3-E209D6D2E59EIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” (P.9-2). 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) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification 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 additivesGUID-9E75C8D6-814E-4BD1-BCD1-16235F7FBEB1INFINITI 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 viscosityGUID-8F8E9479-970D-4961-A158-B90660C9C234The engine oil viscosity or thickness
changes with temperature. Because of this,
it is important 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 recommended
could cause serious engine damage.
Selecting the correct oil filterGUID-9B993B66-0673-49BD-8C4D-409281450A66Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine oil filter or its
equivalent for the reason described in
change intervals.
Change intervalsGUID-F52EE258-6ADA-49F3-A839-FCF212BBD17BThe 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 reduce 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 warran-
ties.
Your engine was filled with a high quality
engine oil when it was built. You do not
have to change the oil before the first
recommended change interval. Oil and
filter change intervals depend upon how
you use your vehicle. Operation under the
following conditions may require more
frequent oil and filter changes.
.repeated short distance driving at cold
outside temperatures,
. driving in dusty conditions,
. extensive idling,
. stop and go “rush hour”traffic,
Refer to the “INFINITI Service and Main-
tenance Guide” for the maintenance sche-
dule.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
GUID-DA065BA2-96F6-4EA0-A393-35BEA4197869The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system oil Type S
or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
Contact an INFINITI retailer when servicing
your air conditioning system.
