SERVICE VEHICLE SOON – 3: This message is
displayed when a non-emissions related powertrain
malfunction occurs. Have your vehicle serviced by a
technician as soon as possible.
SPEED LIMIT TO 90 – 113: A failure in the suspension
control system has occurred when this message appears.
The Powertrain Control Module (PCM) determines the
speed to which your vehicle is limited. Have your vehicle
serviced if this message appears.
STABILITY SYS ENGAGED – 55: You may see the
STABILITY SYS ENGAGED message on the Driver
Information Center. It means that an advanced,
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you are
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or other
slippery spot on the road. When the system is on, you
may hear a noise or feel a vibration in the brake pedal.
This is normal.
When the STABILITY SYS ENGAGED message is on,
you should continue to steer in the direction you want to
go. The system is designed to help you in bad weather or
other difficult driving situations by making the most of
whatever road conditions will permit. If the STABILITY
SYS ENGAGED message comes on, you will know that
something has caused your vehicle to start to spin, so
you should consider slowing down. A single chime will
also sound when this message is displayed.
3-68
STARTING DISABLED REMOVE KEY – 33: This
message will appear when the PASS-Key
detects that an improper ignition key is being used to try
to start the vehicle. Check the ignition key for damage.
If it is damaged, it may need to be replaced. If it is
not damaged, remove the key and try to start the vehicle
again. If it still does not start, try another ignition key
or see your dealer for service.
THEFT ATTEMPTED – 40: This message is displayed
if the theft system has detected a break-in attempt
while you were away from your vehicle.
TOP SPEED FUEL CUT-OFF – 111: This message will
appear when the Powertrain Control Module (PCM)
detects that the maximum speed for your vehicle has
been reached. The speed of your vehicle will surge
as the fuel supply is cut off. Your vehicle's top speed is
based on the top speed rating of the tires. This
ensures that your vehicle stays in a safe operating
range for the tires.
TRACTION ENGAGED – 91: When your traction
control system is limiting wheel spin, the TRACTION
ENGAGED message will be displayed. Slippery
road conditions may exist if this message is displayed,
so adjust your driving accordingly. This message
will stay on for a few seconds after the traction control
system stops limited wheel spin.
