Driving WARNING: Do not drive your vehicle until you verify that the brakelamps are working. WARNING: Always set the parking brake fully and make sure the gearshift is latched in P (Park). Turn the ignition to the off position and remove the key whenever you leave your vehicle. WARNING: If the parking brake is fully released, but the brake warning lamp remains illuminated, the brakes may not be working properly. See your authorized dealer. Driving with a 6-speed automatic transmission Your vehicle has been designed to improve fuel economy by reducing fuel usage during coasting or deceleration. When you take your foot off the accelerator pedal and the vehicle begins to slow down the torque converter clutch locks up and aggressively shuts off fuel flow to the engine while decelerating. This fuel economy benefit may be perceived as a light to medium braking sensation when removing your foot from the accelerator pedal. This vehicle is equipped with an Adaptive Transmission Shift Strategy. The Adaptive Transmission Shift Strategy offers the optimal transmission operation and shift quality. When the engine is turned off, the shift data which includes the adaptive information will be stored automatically in the Powertrain Control Module (PCM) and Transmission Control Module (TCM). If the battery is disconnected for any reason, the stored information from the last time the key was turned to OFF will be read. This way, no information will be lost with any battery removal or battery disconnect. 267 2009 Navigator (nav) Owners Guide, 2nd Printing USA (fus)
