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, the
differential 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 flashes and the cruise
control automatically disengages. The cruise control can
be re-engaged when road conditions allow. See
Cruise Control on page 4-8.

Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. See Accessories and
Modifications
on page 6-3 for more information.

Enhanced Traction System (ETS)

The vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if
it senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transmission to limit wheel spin.

If the vehicle has ETS, there is not an ESC/TCS button
on the instrument panel. To turn the system off, shift
to L (Low) or R (Reverse). There is more information
about how to turn the system off later in this section.

The ETS indicator/warning light flashes and LOW
TRACTION appears on the Driver Information Center
(DIC) when the traction control system is actively limiting
wheel spin. The system may be heard or felt while it
is working, but this is normal. Slippery road conditions
may exist if this message is displayed, so adjust
your driving accordingly.

If the vehicle is in cruise control when the ETS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. See Cruise Control on page 4-8.
