Enhanced Traction System (Ets) - Pontiac Sunfire 2003 Owner's Manual

Enhanced Traction System (ETS)

If your vehicle has the optional four-speed automatic
transaxle and anti-lock brakes, it also has 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.

This light will come on when your Enhanced Traction
System is limiting wheel spin. See Enhanced Traction
System Active Light on page 3-27 . You may feel or hear
the system working, but this is normal.
The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high as the shift lever position you've
chosen, so you should use the lower gears only
when necessary. See Automatic Transaxle Operation on
page 2-22 .

When the system is on and the parking brake is fully
released, this warning light will come on to let you know
if there's a problem.
See Enhanced Traction System Warning Light on
page 3-26 . 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
Canada
Traction System on. But you can turn the system off if
you prefer.
