Vehicle Dynamic Control
(VDC) OFF indicator light
This indicator light comes on when the
VDC OFF switch is pushed to the OFF posi-
tion, the transfer case is in the 4LO position
(

not functioning properly. This indicates the
VDC system is not operating.
Push the VDC OFF switch again or restart
the engine and the system will operate normally. For additional information, refer
to “Vehicle Dynamic Control (VDC) system”
in the “Starting and driving” section of this
manual.
The VDC light also comes on when the
push-button ignition switch is in the ON
position. The light will turn off af ter about 2
seconds if the system is operational. If the
light stays on or comes on along with the
indicator light while you are driving,
have the VDC system checked. It is recom-
mended that you visit a NISSAN dealer for
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-
namic Control (VDC) system” in the “Start-
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
and the VDC light will turn off.

The disc brake pads have audible wear
warnings. When a disc brake pad requires
replacement, it makes a high pitched
scraping sound when the vehicle is in mo-
tion, whether or not the brake pedal is de-
pressed. Have the brakes checked as soon
as possible if the warning sound is heard.
Light reminder chime
With the ignition switch placed in the OFF
position, a chime sounds when the driver's
door is opened if the headlights or parking
lights are on.
Turn the headlight control switch off before
leaving the vehicle.
