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 transmission to limit wheel spin. You may feel or hear the system working, but this is normal. The LOW TRACTION message will appear on the Driver Information Center (DIC) when the traction control system is limiting wheel spin. 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 on page 167. The Enhanced Traction System operates in all transmission shift lever positions except PARK (P), NEUTRAL (N) or REVERSE (R). But the system can upshift the transmission 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 122. This light is located on the instrument panel cluster. When the system is on, this light will come on and stay on to let you know if there's a problem, or if the system has been turned off. When this 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 ETS on. But you can turn the system off if you prefer. 255
