Intelligent Key button operation
light
The light blinks only when you press any
button on the Intelligent Key. The light illu-
mination only signifies that the key fob has
transmitted a signal. You may look and/or
listen to verif y that the vehicle has per-
formed the intended operation. The num-
ber of blinks identifies each registered key
(i.e. 1 blink = 1st key,...,4 blinks = 4th key) for
your own identification purposes. If the light does not blink, your battery may
be too weak to communicate to the ve-
hicle. If this occurs, the battery may need to
be replaced. For additional information re-
garding the replacement of a battery, refer
to “Battery replacement” in the “Do-it-
yourself ” section of this manual.
WARNING SIGNALS
To help prevent the vehicle from moving
unexpectedly by erroneous operation of
the Intelligent Key or to help prevent the
vehicle from being stolen, a chime or
buzzer sounds from inside and outside the
vehicle and a warning is displayed in the
instrument panel.
When a chime or beep sounds or a warning
is displayed, be sure to check the vehicle
and the Intelligent Key.
For additional information, refer to
“Troubleshooting guide” in this section and
“Vehicle information display” in the “Instru-
ments and controls” section of this manual.
