During normal operation, the security light will go off approximately three seconds after the key is turned to the RUN ignition position. • Do not drive at any one constant speed, fast or slow, for the first 500 miles (805 km). Do not make full-throttle starts. Do not exceed 5,000 engine rpm. Avoid downshifting to brake, or slow, the vehicle. • Avoid making hard stops for the first 200 miles If the engine stalls and the security light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts. If the engine is running and the security light comes on, you will be able to restart the engine if you turn the engine off.
