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 when the transaxle shift lever is in the REVERSE (R), THIRD (3) or AUTOMATIC OVERDRIVE (D) position and the system 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.

When the transaxle shift lever is in any position other than FIRST (1) or SECOND (2) and the parking brake is fully released, this warning light will come on to let you know if there's a problem with the system. See Enhanced Traction System Warning Light . When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly.

The Enhanced Traction System can operate when the transaxle shift lever is in any position other than FIRST (1) or SECOND (2). To limit wheel spin, especially in slippery road conditions, you should use REVERSE (R), THIRD (3) or AUTOMATIC OVERDRIVE (D). See Automatic Transaxle Operation . If your vehicle ever gets stuck in sand, mud or snow and rocking the vehicle is required, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow .

When you move the shift lever to FIRST (1) or SECOND (2), the system will turn off. The Enhanced Traction System warning light will come on and stay on. If the Enhanced Traction System is limiting wheel spin when you move the shift lever to another position, the system won't turn off right away. It will wait until there's no longer a current need to limit wheel spin.

You can turn the system back on at any time by moving the shift lever to any position other than FIRST (1) or SECOND (2). The Enhanced Traction System warning light should go off.
