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 11 or Traction
Control System (TCS) on page 5 9 and Enhanced
Traction System (ETS) Indicator/Warning Light on
page 4 32 or Electronic Stability Control (ESC)/Traction

serviced by your dealer/retailer as soon as possible.

This message may display if you have a turbocharged
vehicle with Electronic Stability Control (ESC) and if the
hydraulic brake boost is not working or is working
improperly. Have the brake system serviced by your
dealer/retailer as soon as possible.
SVC (Service) TIRE MONITOR
If your vehicle has a Tire Pressure Monitor 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 35. Several
conditions may cause this message to appear. See
Tire Pressure Monitor Operation on page 6 65 for
more information. If the warning comes on and stays
on, there may be a problem with the TPMS. See your
dealer/retailer.

one or more of the vehicle's tires is low. The low tire

message appears on the DIC, stop as soon as you can.

shown on the Tire Loading Information label. See Tires
on page 6 54, Loading the Vehicle on page 5 24, and
