Coordinate inspection efforts through a certified DaimlerChrysler Dealership. WARNING! Fluid level should be checked on a level surface and with the engine off to prevent injury from moving parts and to insure accurate fluid level reading. Do not overfill. Use only manufacturer's recommended power steering fluid. WARNING! Do not remove the A/C Air Filter while the blower is operating or personal injury may result.
