The SERVICE TRACTION
SYSTEM message and the
TCS warning light will
come on to let you know
if there's a problem with
your TCS system. See
"SERVICE TRACTION
SYSTEM Message"
in the Index.
The TCS system automatically comes on whenever
you start your vehicle. To limit wheel spin, especially
in slippery road conditions, you should always leave the
system on. But you can turn the TCS system off if
you ever need to.
To turn the system off,
press the button located
on the console. You can
turn the system ON or OFF
at any time by pressing the
TCS switch. The DIC will
display the appropriate
message when you push
the button.
