To turn the system off,
press the TCS button
located on the instrument
panel switchbank.
If the system is limiting wheel spin when you press the
button, the traction active message will go off, but
the system will not turn off until there is no longer a
current need to limit wheel spin. The TRAC OFF light will
come on to remind you the system is off. You can
turn the system back on at any time by pressing the
button again. The traction control system warning
message should go off.All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin to
slip, the rear wheels will automatically begin to drive
the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
During heavy AWD applications, the engine torque may
be reduced to protect AWD system components. If the
vehicle is exposed to extended heavy AWD usage, the
AWD system will shut itself off to protect the system from
overheating. When the system cools down, the AWD
system will activate itself again automatically; this
cool-down can take up to 20 minutes depending on
outside temperature and vehicle use. SeeAll-Wheel
Drive Disable Warning Message on page 3-46.
