StabiliTrak® Indicator Light This warning light should come on briefly when the engine is started. Engine Coolant Temperature Warning Light The engine coolant temperature warning light will come on when the engine has overheated. 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 it stays on, or comes on when you are driving, there may be a problem with your StabiliTrak® system and your vehicle may need service. When this warning light is on, the system is off and will not limit wheel spin. Adjust your driving accordingly. This light will also flash when the StabiliTrak® system is active. If the StabiliTrak® system warning light comes on and stays on for an extended period of time when the system is turned on, your vehicle needs service. See StabiliTrak® System on page 337 for more information. If this happens you should pull over and turn off the engine as soon as possible. See Engine Overheating on page 410 for more information. Notice: Driving with the engine coolant temperature warning light on could cause your vehicle to overheat. See Engine Overheating on page 410. 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. 224
