Enhanced Traction System Warning Light If your vehicle is equipped with the Enhanced Traction System (ETS), this warning light should come on briefly as you start the engine. If the warning light does not come on, then have it fixed so it will be ready to warn you if there is a problem. If the warning light stays on, or comes on when you are driving, there may be a problem with your Enhanced Traction System and your vehicle may need service. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. See Enhanced Traction System (ETS) on page 246 for more information. Engine Coolant Temperature Warning Light The engine coolant temperature warning light will come on when the engine has overheated. If this happens you should pull over and turn off the engine as soon as possible. See Engine Overheating on page 309 for more information. Notice: Driving with the engine coolant temperature warning light on could cause your vehicle to overheat. See Engine Overheating on page 309. Your vehicle could be damaged, and it might not be covered by your warranty. Never drive with the engine coolant temperature warning light on. This light will also come on briefly when starting your vehicle. If it does not, have your vehicle serviced. 187
