4. Lower the vehicle slowly until the tiretouches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence illustrated
(
A,B,C,D,E). Lower the vehicle
completely.
WARNING
∙ Incorrect wheel nuts or improperly tight- ened 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 ve- hicle has been driven for 1,000 km
(621 miles) (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: 113 N·m (83 ft-lb)
The wheel nuts must be kept tightened to
specification at all times. It is recommended
that wheel nuts be tightened to specifica-
tions 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 1.6 km (1 mile).
COLD tire pressures are shown on the Tire
Placard affixed to the driver side center pil-
lar.
5. Securely store the flat tire, tools and jacking equipment in the vehicle.
6. Close the liftgate.
WARNING
∙ Always make sure that the spare tire and jacking equipment are properly secured
after use. Such items can become danger-
ous projectiles in an accident or sudden
stop.
∙ The spare tire is designed for emergency use. For additional information, refer to
“Wheels and tires” in the “Maintenance
and do-it-yourself” section of this
manual. ∙ When re-installing the spare tire under
the vehicle after use, be sure to secure it
with the tire stem facing down toward
the ground. If the spare tire is improperly
secured with the tire stem facing up to-
wards the bottom of the vehicle, there is
an increased risk of separating from the
vehicle in the event of crash which may
pose a hazard in traffic or risk of injury to
others.

2. Start the engine and let it idle until itreaches operating temperature, then
turn it off.
3. Remove the oil filler cap
Aby turning it
counterclockwise. 4. Place a large drain pan under the drain
plug
B.
5. Remove the drain plug
Bwith a wrench
by turning it counterclockwise and com-
pletely drain the oil.
If the oil filter is to be changed, remove
and replace it at this time. For additional
information, refer to “Changing engine
oil filter” in this section.
∙ Waste oil must be disposed of properly.
∙ Check your local regulations.
WARNING
∙ Prolonged and repeated contact with
used engine oil may cause skin cancer.
∙ Try to avoid direct skin contact with used oil. If skin contact is made, wash thor-
oughly with soap or hand cleaner as soon
as possible.
∙ Keep used engine oil out of reach of children.
CAUTION
Be careful not to burn yourself. The engine
oil may be hot. 6. Clean and reinstall the drain plug and a
new washer. Securely tighten the drain
plug with a wrench. Do not use excessive
force.
Drain plug tightening torque: 34 N·m (25 ft-lb)
7. Refill engine with recommended oil through the oil filler opening, then install
the oil filler cap securely.
For additional information on drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information”
section of this manual.
The drain and refill capacity depends on
the oil temperature and drain time. Use
these specifications for reference only.
Always use the dipstick to determine
when the proper amount of oil is in the
engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Cor-
rect as required.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.

If you install snow tires, they must be the
same size, brand, construction and tread pat-
tern on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some states,
provinces and territories prohibit their use.
Check local 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
CAUTION
Tire chains/cables should not be installed
on 235/55R20 size tires. Installation of the
tire chains/cables on 235/55R20 size tires
will cause damage to the vehicle. If you plan
to use tire chains/cables, you should install
235/65R18 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 ev-
ery 10,000 km (6,000 miles) for 2WD ve-
hicles and 5,000 km (3,000 miles) for AWD
vehicles.
For additional information on tire replacing
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.
