PRECAUTIONS
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to  ON position, then to LOCK position. (The steering
wheel will lock when the push-button igniti on switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
Service Notice or Precautions for TPMSINFOID:0000000006225485
 Low tire pressure warning lamp blinks for 1min, then turns ON when occurring any malfunction except low tire pressure. Erase the self-diagnosis memories for low  tire pressure warning control unit, or register the ID
to turn low tire pressure warning lamp OFF. For ID registration, refer to  WT-29, "
Work Procedure".
 ID registration is required when replacing or rotating wheel s, replacing transmitter or low tire pressure warn-
ing control unit. Refer to  WT-29, "
Work Procedure".
 Replace grommet seal, valve core and cap of transmitter  in TPMS, when replacing each tire by reaching the
wear limit. Refer to  WT-66, "
Exploded View".
 For tire inflation indicator function, refer to the following.
- When inflating the tires, park the vehicle in the  safe area and ensure the safety of the working area.
- Read and understand the tire inflation indicator function prior to use.
- Inflate the tires one at a time.
- If there is no response for approximately 15 seconds or mo re after inflating the tires, cancel the use of the
tire inflation indicator function or move the vehicle approximately 1 m (3.2 ft) backward or forward to try
again. The air filler pressure may be weak or out of service area.
- Despite the high-precision TPMS pressure sensor, an i ndicated value may differ from that of the pressure
gauge. 
- Air pressure is measured rather high due to the rise in tire air temperature after driving.
- If TPMS is malfunctioning, the tire inflation indicator is unusable.
Service Notice or Precautions for Road WheelINFOID:0000000006225486
 Genuine NISSAN aluminum wheel is designed for each type  of vehicle. Use it on the specified vehicle only.
 Use Genuine NISSAN parts for the wheel nuts.
 Always use them after adjusting the wheel balance.  For the balance weights, use Genuine NISSAN alumi-
num wheel weights.
 Use caution when handling the aluminum wheels,  because they can be easily scratched. When removing
dirt, do not use any abrasives, a wire brush, or other it ems that may scratch the coating. Use a neutral deter-
gent if a detergent is needed.
 After driving on roads scattered with anti-ici ng salts, wash off the wheels completely.
 When installing road wheels onto the vehicle, always wipe of f any dirt or foreign substances to prevent them
from being trapped between the contact surfaces of wheel.
 Never apply oil to nut and bolt threads.
