SERVICE TRACTION
CONTROL
If your vehicle has StabiliTrak, this
message displays when there is a
problem with the Traction Control
System (TCS). When this message
displays, the system will not limit
wheel spin. Adjust your driving
accordingly. See your dealer for
service. See StabiliTrak
page 9 41 for more information.
STABILITRAK OFF
If your vehicle has StabiliTrak, this
message displays when you turn off
StabiliTrak, or when the stability
control has been automatically
disabled. To limit wheel spin and
realize the full benefits of the
stability enhancement system, you
should normally leave StabiliTrak
on. However, you should turn
StabiliTrak off if your vehicle gets
stuck in sand, mud, ice, or snow
and you want to rock your vehicle
to attempt to free it, or if you are
driving in extreme off-road
conditions and require more wheel
spin. See If the Vehicle is Stuck on
page 9 20. To turn the StabiliTrak
system on or off, see StabiliTrak
System on page 9 41.

The message could display if the

diagnostic checks due to driving
conditions.
The message displays if an
engine or vehicle related

and the vehicle needs service.
