lUse extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress on
the emergency towing eyelets and the cables or chains. Always be cautious of the
surroundings and other vehicles while towing.
lIf the engine is not running, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
