TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P255/45RF20 size tires. Installation of
the tire chains/cables on P255/45RF20
size tires will cause damage to the vehicle. If
you plan to use tire chains/cables, you
should install P235/55RF19 size tires on
your vehicle.
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 restricted
tire to vehicle clearance. Vehicles that can use
Class “S” chains are designed to meet the
minimum clearances between the tire and the
closest vehicle suspension or body compo-
nent required to accommodate the use of a
winter traction device (tire chains or cables).
The minimum clearances are determined us-
ing the factory equipped tire size. Other types
may damage your vehicle. Use chain tension-
ers when recommended 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 whip-
ping action damage to the fenders or under-
body. If possible, avoid fully loading your ve-
hicle 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.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 7,500 miles (12,000 km).
For additional information on tire re-
placing procedures, refer to “Flat tire”
in the “In case of emergency” section
of this manual.
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.

8-34Do-it-yourself

Engine coolant*:Replace coolant at the
specified interval. When adding or replacing
coolant, be sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue) or
equivalent with the proper mixture. (For ad-
ditional information on the proper mixture for
your area, refer to “Engine cooling system” in
the “Do-it-yourself” section of this manual.)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine oil and oil filter: Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity refer to
“Recommended fluids/lubricants and capaci-
ties” in the “Technical and consumer informa-
tion” section of this manual.
Engine valve clearance*: Inspect only if valve
noise increases. Adjust valve clearance if nec-
essary.
Evaporative emissions control vapor lines*:
Check vapor lines for leaks or looseness.
Tighten connections or replace parts as nec-
essary. Fuel lines*:
Check the fuel hoses, piping and
connections for leaks, looseness, or deterio-
ration. Tighten connections or replace parts
as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing, cracks,
deterioration, and signs of leaking. Replace
any deteriorated or damaged parts immedi-
ately.
Brake pads and rotors: Check for wear, de-
terioration and fluid leaks. Replace any dete-
riorated or damaged parts immediately.
Exhaust system: Visually inspect the exhaust
pipes, muffler and hangers for leaks, cracks,
deterioration, and damage. Tighten connec-
tions or replace parts as necessary.
In-cabin microfilter: Replace at specified in-
tervals. When driving for prolonged periods in
dusty conditions, replace the filter more fre-
quently. Propeller shaft(s):
Check for damage, loose-
ness, and grease leakage. (AWD)
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots: Check for dam-
age, looseness, and leakage of oil or grease.
Under severe driving conditions, inspect more
frequently.
Tire rotation: Tires should be rotated every
7,500 miles (12,000 km) according to the
instructions under “Explanation of general
maintenance items” in this section. When ro-
tating tires, check for damage and uneven
wear. Replace if necessary.
Transmission fluid/oil, differential oil and
transfer case oil: Visually inspect for signs of
leakage at specified intervals.
Replace at specified intervals.
9-6Maintenance and schedules

NOTE:
Maintenance items with “” should be performed more frequently according to “ Maintenance under severe driving conditions”.
(1) If operating mainly in dusty conditions, more frequent maintenance may be required.
(2) If towing a trailer, using a camper or a car-top carrier or driving on rough or muddy roads, inspect CVT fluid deterioration every
60,000 miles (96,000 km), then change CVT fluid if necessary. And if the inspection is not performed, change (not just inspect) CVT fluid
every 60,000 miles (96,000 km).
(3) After 30,000 miles (48,000 km) or 48 months, inspect every 7,500 miles (12,000 km) or 12 months.
Replace the drive belts if found damaged.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles
(120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50%
demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy of the
factory fill coolant.
(6) If the oil replacement indicator is displayed, change the engine oil and filter within two weeks or less than 500 miles (800 km).
(7) Periodic maintenance is not required.
(8) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
(9) Replace spark plug when the plug gap exceeds 0.045 in (1.25 mm) even if within specified replacement mileage.
(10) For additional information on tire rotation, refer to “General maintenance” in the section
(11) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil every 20,000 miles
(32,000 km) or 24 months.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform such
maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are required.

Steps for determining correct load
limit
1. Locate the statement “The com-bined weight of occupants and
cargo should never exceed XXX
lbs. or XXX kg” on your vehicle’s
Tire and Loading Information la-
bel.
2. Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
XXX lbs. or XXX kg.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For ex-
ample, if the XXX amount equals
1,400 lbs. and there will be five
150 lbs. passengers in your ve-
hicle, the amount of available
cargo and luggage load capacity
is 650 lbs. (1,400-750 (5 X 150)
= 650 lbs.) or (640-340 (5 X 70) =
300 kg.) 5. Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed the
available cargo and luggage load
capacity calculated in step 4.
6. If your vehicle will be towing a trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity
of your vehicle.
Before driving a loaded vehicle, con-
firm that you do not exceed the GVWR
or the GAWR for your vehicle. For ad-
ditional information, refer to “Mea-
surement of weights” in this section.
Also check tires for proper inflation
pressures. For additional information,
refer to “Tire and Loading Information
label” in the “Do-it-yourself” section of
this manual.
SECURING THE LOAD
There are luggage hooks located in the cargo
area as shown. The hooks can be used to
secure cargo with ropes or other types of
straps.
When securing items using luggage hooks
located on the side finisher do not apply a
load over more than 6.5 lbs. (29 N) to a single
hook.
The luggage hooks that are located on the
floor should have loads less than 110 lbs.
(490 N) to a single hook.
