ADDITIONAL MAINTENANCE ITEMS

• Inspect the tire side wall for damage.
• Check the tire pressure and adjust the pressure as necessary when the tires are cold.
Tire pressure:
When the tire temperature has increased after the vehicle was driven at high speed or you have engaged in
high performance driving, adjust the tire pressure as follows to balance the rigidity between the front and rear
tires.

The tire pressure changes depending on the outside temperature or altitude. Check the tire pressure regularly
and when the climate conditions change.

WARNING:

Keep your tires inflated to the correct tire pressure. Driving with low tire pressure can damage some
powertrain systems and affect the operation of the ABS and VDC systems. Low tire pressure may also
cause tire failure and result in serious personal injury or death.
• Make sure the tire valve stem cap is installed and that the valve stem is tight. When installing the cap, make

sure to tighten the cap by hand. If a tool is used to tighten the cap, the cap may be damaged.

• Make sure the wheel nuts are tight.
• Make sure the drive shaft nuts are tight.
• Make sure to replace the grommet seal, the valve core and the valve cap of the Tire Pressure Monitoring

System (TPMS) sensor attached to the wheel every 3 years for performance driving use. Replace them
every 5 years even when not engaging in performance driving. A dirty grommet seal will cause the air leak
from the tire.

• Make sure that the TPMS sensor installation nuts and the sensor valve are tight and there is no nitrogen

leak.

• Use only a NISSAN genuine valve cap or equivalent.
• Check wheel hub run out and that the wheel rotates smoothly without any friction. Check these with the tires

removed whenever an inspection is performed with the vehicle jacked up.

• Secure road wheel balance weights with aluminum tape.
• Check that the wheel nuts are not stripped.
• Make sure the tire has not slipped on the wheel causing the assembly to be out of balance. The reference

marks on the tire and wheel should be aligned. If the reference marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires rebalanced. Make sure the old reference marks are erased and new refer-
ence marks are applied to the wheel and tire. When installing new tires on the wheels, make sure new refer-
ence marks are applied to the wheels and tires.

BRAKES

• Check for the heat deterioration of the brakes and parts around the brakes.
• It is recommended that you remove air from the brake system after any of the following:

- When engaging in high performance driving for the first time after purchasing a new vehicle.
- After replacing the brake fluid.
- When engaging in high performance driving for a sustained period of time.

It is recommended that bleeding the brake be performed when the brake calipers are hot (about 212

°

F

(100

°

C)).

Brake Pad:
• NISSAN recommends adding an additional cross spring to the front calipers before engaging in performance

driving. The additional spring reduces brake pad movement resulting from cornering forces and will reduce
the stroke of the brake pedal. If a cross spring is added, a clattering or squeaking sound may be heard on
rare occasions.

Brake Pad Brake-in Procedure:
NISSAN recommends performing the brake pad break in procedure until the surface of the brake pad is cov-
ered with a 0.04 to 0.08 in (1 to 2 mm) thick white coating. To achieve this result the temperature of the brake
pads must reach 1,112

°

F (600

°

C). To achieve this result perform the following:

• Drive the vehicle at a speed of 75 MPH (120 km/h) and slow down to 12 MPH (20 km/h) with a 0.6G rate of

braking. Repeat this procedure about 15 times.

• Cool down the brakes by driving at 37 to 50 MPH (60 to 80 km/h), in 5th or 6th gear for 2 to 3 miles (3 to 5

km) after the break in procedure is completed.

Condition

Inspection and Adjustments after Performance Driving

INFOID:0000000009161754

NOTE:
At the completion of performance driving, all fluids and adjustments should be returned to their normal condi-
tions and settings as specified.

FLUIDS

• Check the engine, transmission, differential and under the vehicle for oil and coolant leaks.
• Check the fluid levels and adjust as necessary using the specified fluid as described under the conditions

listed in RECOMMENDED FLUIDS AND MAINTENANCE INTERVAL. If you do not drive under the condi-
tions listed, refer to the applicable NISSAN Service and Maintenance Guide.

• When changing fluids, be sure to use the specified fluids as described in the RECOMMENDED FUELS/

LUBRICANTS Chart in the Technical and Consumer Information section of owner's instruction.

ADDITIONAL MAINTENANCE ITEMS

*1: Mobil 1 (0W-40) (100% synthetic) is the factory fill oil. The VR38 engine with its plasma-sprayed bores was developed using this oil.
NISSAN cannot ensure proper engine operation and durability if other 0W-40 synthetic oil is used. If Mobil 1 (0W-40) is not available,
Mobil 1 (10W-40) (100% synthetic) may be used, however, some performance loss may be noticed.

*2: The differential oil temperature cannot be displayed on the multi function display. The differential oil temperature can be checked with
the transmission oil temperature since both usually increases or decrease concurrently.

*3: Genuine NISSAN Brake Fluid R35 Special II is the factory fill brake fluid. The Vehicle Dynamic Control (VDC) unit and other related
parts were specially designed for this brake fluid and NISSAN cannot ensure the best performance and proper operation of the vehicle if
other brake fluid is used.

SUSPENSION and WHEEL ALIGNMENT

• Check the steering and suspension system and other links for loose and/or damaged parts.
• Measure and adjust the wheel alignment.
Preventing Toe-out:
Regarding the amount of toe-in, because toe-out causes lopsided wear on the tires or damage to localized
areas inside the tires due to heat generation, be sure to adjust to toe-in. Also, heat may be generated in local-
ized areas if the toe-in amount is excessive. Particularly when engaging in high performance driving or driving
at extremely high speed, be sure to adjust the front toe-in to 0.059 in (1.5 mm) or less, and rear toe-in to 0.079
in (2.0 mm) or less. Any damage caused by failing to adjust the toe-in within the specified range will not be
covered by warranty.

WHEEL and TIRES

• Check tire wear and cracking.
• Inspect the tire side wall for damage.
• Check the tire pressure and adjust the pressure as necessary when the tires are cold.

(See previous page's charts)

• Check that the wheel nuts are not stripped. Check if there is no deformation on the contact surface of the

nuts.

• Make sure the wheel nuts are tight.
• Make sure the drive shaft nuts are tight.
• Check wheel hub run out and that the wheel rotates smoothly without any friction. Check these with the tires

removed whenever an inspection is performed with the vehicle jacked up.

• Make sure the tire has not slipped on the wheel causing the assembly to be out of balance. The reference

marks on the tire and wheel should be aligned. If the reference marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires rebalanced. Make sure the old reference marks are erased and new refer-
ence marks are applied to the wheel and tire. When installing new tires on the wheels, make sure new refer-
ence marks are applied to the wheels and tires.

• Make sure that the TPMS sensor installation nuts and the sensor valve are tight and there is no nitrogen

leak.

BRAKES

• Check for the heat deterioration of the brakes and parts around the brakes.
• Check the condition of the brake pads and disc rotors and replace them as necessary.

ENGINE and POWERTRAIN

• Inspect the area surrounding the catalytic converter for heat deterioration.
• Inspect to see whether the clearance between the exhaust finisher and rear bumper is maintained at above

0.24 in (6 mm) (up/down) and above 0.20 in (5 mm) (left/right).

• Inspect drive shaft universal joint dust boots for cracks and damage. Replace as necessary.
• Check the engine, transmission, differential and under the vehicle for oil and coolant leaks.
• The clutch clearance and shift fork position may need to be adjusted.
• Check that there is no abnormal noise, vibrations or warning lights illuminated when making tight turns at

slow speed (for tight corner braking phenomenon).
