Traction Control Operation
The traction control system is part of the ESC
system. Traction control limits wheel spin by
reducing engine power to the wheels (engine
speed management) and by applying brakes to
each individual wheel (brake-traction control)
as necessary.
The traction control system is enabled
automatically when you start your vehicle, and it
will activate and display the LOW TRACTION
message if it senses that any of the wheels are
spinning or beginning to lose traction while driving.
If you turn off traction control, the TCS OFF
warning light will come on and the TRACTION
OFF message will be displayed The ESC system
will remain operational unless it is turned off.
For more information on the traction active
message, see Driver Information Center (DIC)
on page 204.
Notice: If you allow the wheel(s) of one axle
to spin excessively while the ESC, ABS and
brake warning lights and the SERVICE ESC
message are displayed, you could damage
the transfer case. The repairs would not be
covered by your warranty. Reduce engine
power and do not spin the wheel(s) excessively
while these lights and this message are
displayed.
The traction control system may activate on
dry or rough roads or under conditions such as
heavy acceleration while turning or abrupt
upshifts/downshifts of the transmission. When this
happens, you may notice a reduction in
acceleration, or may hear a noise or vibration.
This is normal.
If your vehicle is in cruise control when the system
activates, the ESC ACTIVE message will appear
and the cruise control will automatically disengage.
When road conditions allow you to use cruise
again, you may re-engage the cruise control.
See Cruise Control on page 167.
ESC may also turn off automatically if it determines
that a problem exists with the system. If the
problem does not clear itself after restarting the
vehicle, you should see your retailer for service.
Adding non-dealer/non-retailer accessories
can affect your vehicle’s performance. See
Accessories and Modifications on page 297 for
more information.
