If the driver’s door is opened while the ignition is switched to ACC, a
continuous beep sound will be heard to notify th e driver that the igni-
tion has not been switched off (STOP). Left in this condition, the key-
less entry system will not operate, the car cannot be locked, and the
battery power will be depleted.
A beep sound will be hear d 6 times and the KEY warning light (red)
will flash continuously if the ignition has not been switched off, all the
doors are closed, and the key is remo ved from the vehicle. This is to
notify the driver that the key has been removed from the vehicle and
the ignition has not been switched off.
Because the key utilizes low-intensity radio waves, the Key Removed From
Vehicle Warning may activate if the key is carried together with a metal object
or it is placed in a poor signal reception area.
The warning beep sound will be heard for about 3 seconds when
there is any abnormality in tire inflation pressures (→P. 218).
If there is the possibility of a collis ion with a vehicle ahead, the beep
sounds continuously and a warning is indicated in the display.
If the power steering system has a malfunction, the power steering
malfunction light turns on or flashes and the buzzer operates at the
same time.
