This symbol comes on the Driver Information Center (DIC) when the ETS is limiting wheel spin. If the vehicle is in cruise control when ETS begins to limit wheel spin, the cruise control will automatically disengage. When road conditions allow safe use of it, the cruise control can be used again. See Cruise Control on page 140. ETS operates in all transaxle shift lever positions. But the system can upshift the transaxle only as high as the chosen shift lever position, so use the lower gears only when necessary. See Automatic Transaxle Operation on page 110. One of these lights will appear on the instrument panel to indicate that the ETS is not on. This symbol, along with the message TRACTION CONTROL OFF will display on the DIC for three seconds when the ETS is not on. If there is a problem with the system, the service traction system will also come on in the DIC. See Enhanced Traction System Warning Light on page 179. When this warning light is on, the system will not limit wheel spin. Adjust driving accordingly. 294
