To turn the system off or
on, press and release the
ESC/TCS button located
on the instrument panel.
The DIC displays the appropriate message as described
previously when the button is pressed.
Traction Control Operation
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 the vehicle is started, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that either of the front wheels are
spinning or beginning to lose traction while driving.
For more information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-48.
Notice:If the wheel(s) of one axle are allowed
to spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, thedifferential could be damaged. The repairs would not
be covered by the vehicle warranty. Reduce engine
power and do not spin the wheel(s) excessively while
these lights and this message are displayed.
Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the drive
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not attempt
to shift when the drive wheels do not have traction.
Damage caused by misuse of the vehicle is not
covered. See the warranty book for additional
information.
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, a reduction
in acceleration may be noticed or a noise or vibration
may be heard. This is normal.
If the vehicle is in cruise control while the system
activates, the ESC/TCS light ashes and the cruise
control automatically disengages. The cruise control can
be re-engaged when road conditions allow. SeeCruise
Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-11

If the ETS indicator/warning light comes on and stays on
for an extended period of time when the transmission
shift lever is in any position other than L (Low), the
vehicle may need service.
When this light is on solid, the system will not limit
wheel spin. Adjust your driving accordingly.
Check the DIC messaging to determine whether it is
because of the driver turning off the system, or that the
system may not be working properly and the vehicle
requires service. When this light is turned on, either the
SERVICE TRACTION or TRACTION OFF message
will be displayed.
SeeDIC Warnings and Messages on page 3-50for
more information on the messages associated with
this light.
To limit wheel spin, especially in slippery road
conditions, ETS should always be left on. But the
system can be turned off if needed.
To turn the system off, shift to L (Low) or R (Reverse).
When the system is turned off, the ETS indicator/warning
light will come on and stay on and the TRACTION OFF
message will be displayed when the gear shift is in
L (Low). The indicator/warning light and message will
not come on when the gear shift is in R (Reverse).If the ETS is limiting wheel spin when the transmission is
shifted to L (Low) or R (Reverse) to turn the system off,
the indicator/warning light and TRACTION OFF will come
on in L (Low). But the system will not turn off right away.
It will wait until there is no longer a current need to limit
wheel spin. SeeDIC Warnings and Messages on
page 3-50for more information on the messages
associated with this light.
The system can be turned back on at any time by
shifting to D (Automatic Overdive) or I (Intermediate).
The ETS indicator/warning light should go off.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
Limited-Slip Differential
Vehicles with a limited-slip differential can give more
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when traction
is low, this feature allows the drive wheel with the most
traction to move the vehicle. The limited slip design
has minimal impact to the steering feel, but boosts the
traction performance under all conditions.
