If Trouble Arises
Warning/Indicator Lights and Warning Sounds
Seat Belt Warning Beep
If the driver's seat belt is not fastened
when the ignition is switched ON, a beep
sound will be heard for about 6 seconds. If
the driver or the front passenger's seat belt
is not fastened and the vehicle is driven
at a speed faster than about 20 km/h (12
mph), a beep sound will be heard again for
a speci¿ ed period of time.
N O T E
 y  Placing heavy items on the front
passenger seat may cause the front
passenger seat belt warning function to
operate depending on the weight of the
item.
 y To allow the front passenger seat weight
sensor to function properly, do not place
and sit on an additional seat cushion
on the front passenger seat. The sensor
may not function properly because the
additional seat cushion could cause
sensor interference.
 y When a small child sits on the front
passenger seat, it is possible that the
warning beep will not operate.

Ignition Not Switched Off (STOP) Warning Beep
If the driver's door is opened with the
ignition switched to ACC, a beep will
be heard continuously in the cabin to
notify the driver that the ignition has not
been switched OFF (STOP). Under this
condition, the keyless entry system will
not operate, the vehicle cannot be locked,
and the battery voltage will be depleted.

If the key is taken out of the vehicle while
the ignition is not switched OFF and
all the doors are closed, the beep which
sounds outside of the vehicle will be heard
6 times, the beep which sounds inside
the vehicle will be heard 6 times, and the
KEY warning light (red) in the instrument
cluster À ashes continuously to notify
the driver that the ignition has not been
switched OFF.
Vehicles without advanced keyless
function

the ignition is not switched OFF and all
the doors are closed, a beep will be heard
in the cabin 6 times and the KEY warning
light (red) in the instrument cluster turns
on continuously to notify the driver that
the ignition has not been switched OFF.
N O T E

radio waves, the Key Removed From

carried together with a metal object or it
is placed in a poor signal reception area.

Request Switch Inoperable Warning Beep (With the advanced
keyless function)
If the request switch is pressed with the
door open or ajar, or the ignition is not
switched OFF with a key being carried,
a beep will be heard outside for about 2
seconds to notify the driver that the door
or liftgate/trunk lid cannot be locked.
