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.
