Driving Operating the vehicle with the snowplow attached Do not use your vehicle for snow removal until it has been driven at least 500 miles (800 km). The attached snowplow blade restricts airflow to the radiator, and may cause the engine to run at a higher temperature: Attention to engine temperature is especially important when outside temperatures are above freezing. Angle the blade to maximize airflow to the radiator and monitor engine temperature to determine whether a left or right angle provides the best performance. Follow the severe duty schedule in your scheduled maintenance information for engine oil and transmission fluid change intervals. Snowplowing with your airbag-equipped vehicle Your vehicle is equipped with a driver and passenger airbag Supplemental Restraint System (SRS) The SRS is designed to activate in certain frontal and offset frontal collisions when the vehicle sustains sufficient longitudinal deceleration. Careless or high speed driving while plowing snow which results in sufficient vehicle decelerations can deploy the airbag. Such driving also increases the risk of accidents. WARNING: All occupants of the vehicle, including the driver, should always properly wear their safety belts, even when an air bag supplemental restraint system (SRS) is provided. Never remove or defeat the "tripping mechanisms" designed into the snow removal equipment by its manufacturer. Doing so may cause damage to the vehicle and the snow removal equipment as well as possible airbag deployment. WARNING: Do not attempt to service, repair, or modify the air bag supplemental restraint system (SRS) or its fuses. See your Ford or Lincoln Mercury dealer. WARNING: Additional equipment such as snowplow equipment may effect the performance of the airbag sensors increasing the risk of injury. Please refer to the Body Builders Layout Book for instructions about the appropriate installation of additional equipment. 312 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
