Buick 2009 Enclave - Manual (Page 244)

This light, along with the
TRACTION CONTROL
OFF message, will display
briefly on the DIC when
TCS is not on.
If there is a problem with the system, the SERVICE
TRACTION SYSTEM message will also come on in the
DIC. When this warning light is on, the system will
not limit wheel spin. Adjust driving accordingly.
To limit wheel spin, especially in slippery road
conditions, TCS should always be left on. But the
system can be turned off if needed. TCS should be
turned off if the vehicle ever gets stuck in sand, mud or
snow and rocking the vehicle is required. See Rocking
Your Vehicle to Get It Out on page 4-20 and If Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-19.
To turn TCS on or off, press the TCS button located
above the radio.
When TCS is turned off, the TCS warning light will
come on along with the TRACTION CONTROL OFF
message on the DIC. It will turn off when TCS is turned
back on. If TCS is limiting wheel spin when the TCS
button is pressed, the TCS warning light will come
on and TCS will turn off right away.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. See Accessories and
Modifications on page 5-3 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.
The system may be heard or felt while it is working, but
this is normal.
The TRACTION CONTROL ACTIVE message on the
Driver Information Center (DIC) will be displayed
when the system is limiting wheel spin.
