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 4-7.
The ETS indicator/warning light may come on for the
following reasons:
The indicator/warning light flashes while the traction
control system is limiting wheel spin.
If the system is turned off by moving the shift lever
to L (Low), the indicator/warning light comes on
and stays on. To turn the system back on, move the
shift lever back to a position other than L (Low).
The indicator/warning light should go off.
The indicator/warning light will come on when the
parking brake is set with the engine running, and it
will stay on if the parking brake does not release fully.
If the transmission shift lever is in any position other
than L (Low) and the indicator/warning light stays on
after the parking brake is fully released, there is a
problem with the system.
If the traction control system is affected by an engine
related problem, the system will turn off and the
indicator/warning light will come on.
