this service.
If the battery is removed or discharged, the
VDC system is disabled and the VDC indi-
cator light will not turn off af ter 2 seconds
when the ignition switch is placed in the ON
position. To reset the system, you must
perform the reset procedure. For addi-
tional information, refer to “Vehicle Dy-

ing and driving” section of this manual.
If the light does not go off af ter performing
the reset procedure, have the traction con-
trol system checked. It is recommended that
you visit a NISSAN dealer for this service.
While the VDC system is operating, you
might feel slight vibration or hear the sys-
tem working when starting the vehicle or
accelerating, but this is normal. The VDC system will be disabled and the
VDC light will illuminate when the elec-
tronic locking rear differential (E-lock) sys-
tem switch (if so equipped) is turned on
and the E-lock system is engaged. If the
E-lock system disengages or the switch is
turned off, the VDC system will be enabled
