4. Open the hoods and locate the positive (+) and negative (−) terminal locations on the other vehicle. You will not see the battery of your vehicle under the hood. It is located under the rear passenger's seat. You will not need to access the battery for jump starting. Your vehicle has a remote positive (+) jump starting terminal and a remote negative (−) jump starting terminal. The remote positive (+) terminal is located in the engine compartment on the passenger's side of the vehicle. Lift the red plastic cap to access the terminal. {CAUTION: An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan. {CAUTION: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You do not need to add water to the battery installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you do not, explosive gas could be present. Battery fluid contains acid that can burn you. Do not get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately. The remote negative (−) terminal is located near the power steering fluid reservoir. It is marked "GND (−)." 5-64
