Check Air Suspension Light
This light glows momentarily when the ignition
is turned to the ON position. With the ignition
on this light will flash five (5) times and sound a
tone for one (1) second, and then the light will
remain on to indicate that the air suspension
switch (located in the trunk on the right side) is
off or to indicate a possible system fault.
If the light is displayed while driving and the
air suspension switch is not turned off, safely
pull off the road as soon as possible. Turn the
ignition switch from ON to OFF and to ON
again. If the light continues to be displayed after
flashing five (5) times, turn the air suspension
switch (located in the trunk on the right side) off
and take your vehicle to a dealership for service
as soon as possible.
