Installed in the doors, these air bags
protect occupants during side impact
collisions exceeding a preset thresh-
old. Unlike normal side air bags,
head-thorax air bags are also designed
to provide protection for the head area.
Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer,
coolant temperature and fuel gauge.
Kickdown*
Depressing the accelerator past the
point of resistance shifts the automatic
transmission down to the lowest possi-
ble gear. This very quickly accelerates
the vehicle and should not be used for
normal acceleration needs.

posted at the pump, also known as
ANTI-KNOCK INDEX.Multifunction display
Two display fields in the instrument
cluster used to present information
provided by the control system.
