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 ‑ 6 .
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.
