Enhanced Traction System (Ets) - Buick 2003 Century Owner's Manual

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 transaxle to limit wheel spin.
LOW TRAC
This light will come on
when your Enhanced
Traction System is limiting
wheel spin. See
Enhanced Traction System
Warning Light on
page 3-33.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the enhanced
traction system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. See 'Cruise Control" under
Turn Signal/Multifunction Lever on page 3-5.
The Enhanced Traction System operates in THIRD (3)
and OVERDRIVE (@). If you are in THIRD (3), the
system can upshift the transaxle to OVERDRIVE
(a).
The Enhanced Traction System is turned off in
SECOND (2) or FIRST (1) gear. See Automatic
Transaxle Operation on page 2-23.
TRAC
OFF
When the system is on,
this warning light will come
on to let you know if
there's a problem.
See Enhanced Traction System Warning Light on
page 3-33. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system off if
you ever need to. You should turn the system off if your
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required. See "Rocking Your
Vehicle To Get It Out" under If You Are Stuck: In Sand,
Mud, Ice or Snow on page 4-31.
