Traction Control System (TCS) (option)
The Traction Control System (TCS) uses
the same wheel sensors as the ABS to de-
termine if one set of drive wheels is
spinning much more rapidly than the wheel
set on the other side. If the TCS determines
that a wheel is spinning (with vehicle speed
below 25 mph [40 km/h]), it operates the
brake system to apply some brake force to
stop the spinning wheel(s). This puts the
drive power over to the stationary wheel(s).
If vehicle speed is above 25 mph
(40 km/h), a signal is sent to the engine
ECU, which reduces the engine speed to be
consistent with vehicle speed. This action
helps reduce the amount of wheel spin and
gives the operator greater vehicle control.

The TCS includes a switch to turn off the
function. When the switch is in the OFF
position, the TCS operates normally to in-
crease traction if the drive wheels are
spinning. When the switch is pressed once,
the TCS telltale in the instrument cluster
blinks continuously, indicating that the TCS
is in mud/snow mode.
The mud/snow mode increases available
traction on soft surfaces like snow, slush or
mud by slightly increasing the allowable
wheel spin. This prevents the wheels from
getting bogged down. The TCS will resume
normal operation when the TCS switch is
pressed again and the TCS telltale goes out
or when the ignition is turned off.
CAUTION
Do not engage the differential locks
while wheels are spinning. Serious dam-
age to the differential will occur. See
page 258 for more information.
