Electronic Stability Control (ESC)/
Traction Control System (TCS)
Indicator/Warning Light
(2.0L Engine Only)
For vehicles that have the Electronic Stability
Control (ESC) system or the Traction Control
System (TCS), this warning light should come on
briefly when the engine is started.
136
This light is located in
the center of the
instrument panel cluster.
If the warning light does not come on then, have it
fixed so it will be ready to warn you if there is a
problem. This light, along with the appropriate
Driver Information Center (DIC) messages,
indicates when the ESC system and the TCS are
working or are disabled.
If this light is on and not flashing, the TCS and
potentially the ESC system have been disabled.
Check your DIC messaging to determine
which feature(s) is no longer functioning and
whether it is because of the driver turning off the
feature(s), or the system may not be working
properly and your vehicle requires service. If the
TCS is disabled, wheel spin will not be limited.
If the ESC system is disabled, the system will not
aid in maintaining vehicle directional control. In
either case, adjust your driving accordingly.
