Enhanced Traction System Warning Light If the vehicle has the Enhanced Traction System, (ETS) the warning light may come on for the following reasons: Low Traction Light If the vehicle has the Enhanced Traction System (ETS), this light will come on when the system is limiting wheel spin. • When the vehicle is shifted to SECOND (2) or FIRST (1). To turn the system back on, shift to THIRD (3) or AUTOMATIC OVERDRIVE (X). See Enhanced Traction System (ETS) on page 4-9. • If the vehicle needs service. Adjust your driving accordingly. • When the parking brake is set with the engine running, and the parking brake does not release fully. After the parking brake is fully released and the transaxle shift lever is in any position other than FIRST (1) or SECOND (2). This means there is a problem with the system. • If an engine-related problem affects the ETS and turns the system off. When the ETS warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. 3-34 You may feel or hear the system working, but this is normal. Slippery road conditions may exist if the low traction light comes on, so adjust your driving accordingly. The light will stay on for a few seconds after the ETS stops limiting wheel spin. See Enhanced Traction System (ETS) on page 4-9. The low traction light also comes on briefly when the ignition key is turned to RUN. If the light does not come on then, have it fixed so it will function properly to indicate when the Enhanced Traction System is active.
