Radiator Pressure Cap Notice: The radiator cap on your vehicle is a pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Be sure the arrows on the cap line up with the overflow tube on the radiator filler neck. The radiator pressure cap is located in the front of the engine compartment on the passenger's side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. If Steam Is Coming From Your Engine {CAUTION: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool. See Overheated Engine Protection Operating Mode on page 5-26 for information on driving to a safe place in an emergency. Engine Overheating There is a coolant temperature gage and a warning light on the instrument panel cluster that indicate an overheated engine condition. See Engine Coolant Temperature Gage on page 3-38 and Engine Coolant Temperature Warning Light on page 3-38 for more information. In addition, if your vehicle is equipped with a Driver Information Center (DIC), you will find an ENGINE COOLANT HOT and a REDUCED POWER STOP WHEN SAFE message displayed on the DIC. See DIC Warnings and Messages on page 3-53 for more information. 5-24
