wheel torque INFINITI G-COUPE 2010 Owners Manual

Installing the spare tire
The T-type spare tire is designed for emergency
use. (See specific instructions under the head-
ing “WHEELS AND TIRES” in the “8. Maintenance
and do-it-yourself” section.)
1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
Models equipped with different sized tires in
the front and rear:
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 wheelnuts alternately and evenly in the se-
quence 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 se-
curely in the sequence as illustrated.
Lower the vehicle completely.
WARNING
●Incorrect wheel nuts or improperly tightened
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 speci-
fication at all times. It is recommended that
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 three
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.SCE0661

●Waste oil must be disposed of properly.
● Check your local regulations.
4. (Perform steps 4 to 7 only when the
engine oil filter change is needed.)
Loosen the oil filter2with an oil filter
wrench. Remove the oil filter by turning it by
hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old rubber gasket re-
maining on the mounting surface of the engine.
Failure to do so could lead to engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten ad-
ditionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(14.7 to 20.5 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m)
Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section for drain and
refill capacity. 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 the proper
amount of oil in the engine.
10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover into positionas the following steps.
a. Pull the center of the small plastic clip out.
b. Hold the engine undercover into position.
c. Insert the clip through the undercover into the hole in the frame, then push the
center of the clip in to lock the clip in
place.
d. Install the other bolts that hold the un- dercover in place. Be careful not to strip
the bolts or over-tighten them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.

Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
tire chains in such conditions can cause dam-
age to the various mechanisms of the vehicle
due to some overstress.
CHANGING WHEELS AND TIRES
Tire rotation (Models equipped with
same size tires on all wheels)
INFINITI recommends rotating the tires
every 7,500 miles (12,000 km). (See
“FLAT TIRE” in the “6. In case of emer-
gency” section for tire replacing proce-
dures.)
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
the specification at all times. It is recom-
mended that wheel nuts be tightened to
the specification at each tire rotation in-
terval.
WARNING
●After rotating the tires, check and ad-
just 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 T-type spare tire or
any other small size spare tire in the
tire rotation.
●For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
