If this message turns on while you are driving, pull off
the road as soon as possible and stop carefully. Try
resetting the system by turning the ignition off and then
back on. If this message still stays on or turns back on
again while you are driving, your vehicle needs service.
Have the ESC inspected by your dealer/retailer as soon
as possible.
SERVICE TRACTION
If your vehicle has the Enhanced Traction System
(ETS) or Traction Control System (TCS), this message
displays and a chime sounds when the system is not
functioning properly. The ETS light or the ESC/TCS light
also appears on the instrument panel cluster. This light
stays on solid as long as the detected problem remains
present. When this message displays, the system is not
working. Adjust your driving accordingly. See Enhanced
Traction System (ETS) on page 5 12 or Traction
Control System (TCS) on page 5 9 and Enhanced
Traction System (ETS) Indicator/Warning Light on
page 4 25 or Electronic Stability Control (ESC)/Traction

If your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS), this message displays if
a part on the TPMS is not working properly. The tire
pressure light also flashes and then remains on during
the same ignition cycle. See Tire Pressure Light on
page 4 27. Several conditions may cause this message
to appear. See Tire Pressure Monitor Operation on
