Buick 2008 Automobile User Manual


 
When the TCS is turned off, the TCS warning light will
come on along with the TRACTION CONTROL OFF
message on the DIC. It will disappear when the TCS is
turned back on. If the TCS is limiting wheel spin
when the TCS button is pressed, the TCS warning light
will come on and the TCS will turn off right away.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. See Accessories and
Modifications on page 5-3 for more information.
Enhanced Traction System (ETS)
Your 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. You may feel or hear the system 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.
If the vehicle is in cruise control when ETS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow safe use of it,
the cruise control can be used again. See Cruise Control
on page 3-10.
The ETS operates in all transmission shift lever
positions. But the system can upshift the transmission
only as high as the chosen shift lever position, so
use the lower gears only when necessary. See
Automatic Transmission Operation on page 2-29.
This warning light, along
with the TRACTION
CONTROL OFF message,
will display on the DIC
for three seconds when the
ETS 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 your driving accordingly.
