Failure to do so can adversely affect the vehicle's future performance, including increased chance of an accident. G Never drive on pavement with activated differential locks. Engaged front axle differential locks limits ability to move around curves. If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the roadway.
