Air Suspension Light (If equipped)
This light tells you if the air suspension needs
repair or if the air suspension switch (in the
trunk on the right side) is OFF.
Normally, the light will glow momentarily as
you turn the ignition key to the ON position. If
it glows continuously:
1. Safely pull off the road as soon as possible.
Turn the ignition key from ON to OFF and
ON again.
2. If the light still glows, check to see if the air
suspension switch is OFF. If it is OFF, push
the switch ON. If it is ON, push the switch
OFF and have the system checked as soon as
possible.
Check Engine Warning Light
The Powertrain On-Board Diagnostic II (OBD II)
system consists of the hardware and software
necessary to monitor the operation of the
powertrain. The OBD II system is designed to
check the function of the vehicle's powertrain
control system during normal operation. If an
emission problem is detected, the Check Engine
Warning Light (in the cluster) is turned on.
Modification or additions to the vehicle may
cause incorrect operation of the OBD II system.
Additions such as burglar alarms, cellular
phones, and CB radios must be carefully
