Have the cause of the problem inspected immediately. l Do not under any circumstances shift the shift lever to "P", "R" or "N" while the vehicle is moving. Doing so can cause significant damage to the transmission and may result in a loss of vehicle control. l Do not shift the shift lever to "N" while the vehicle is moving. Doing so may cause the engine brake not to operate properly and lead to an accident. l Do not turn the engine off while driving. The power steering and brake booster will not operate properly if the engine is not running. l Use engine braking (downshift) to maintain a safe speed when driving down a steep hill. Using the brakes continuously may cause the brakes to overheat and lose effectiveness.
