If the vehicle has an Enhanced Traction System (ETS) it will limit 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 the instrument panel cluster while the ETS is limiting wheel spin. See Enhanced Traction System Warning Light .

You may feel or hear the system working, but this is normal.

If the vehicle is in cruise control when the enhanced traction system begins to limit wheel spin, the cruise control will automatically disengage. The cruise control can be used again when road conditions allow safe use of it. See "Cruise Control" under Turn Signal/Multifunction Lever .

The ETS operates in THIRD (3) and AUTOMATIC OVERDRIVE (Overdrive). If the vehicle is in THIRD (3), the system can upshift the transaxle to AUTOMATIC OVERDRIVE (Overdrive). The ETS is turned off in SECOND (2) or FIRST (1) gear, and when the parking brake is set. See Automatic Transaxle Operation .

While the ETS is on, this warning light will come on the instrument panel cluster to show that the system is not limiting wheel spin.

See Enhanced Traction System Warning Light . Adjust your driving accordingly.

To limit wheel spin, especially in slippery road conditions, the ETS should always be left on. But the system can be turned off . The ETS 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" under If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow .

To turn the system off, move the gear shift lever to FIRST (1) or SECOND (2) gear. See "Rocking Your Vehicle To Get It Out" under If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow . When the system is turned off, the TRAC OFF warning light will come on and stay on. If the ETS is limiting wheel spin when the system is turned off, the TRAC OFF light will come on - but the ETS will not turn off right away. It will continue to operate until there is no longer a need to limit wheel spin.
