Enhanced Traction System (Ets) - Buick Century 2003 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.
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 .
