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.
