pressure for the tire and associated load rating is imprinted on the tire
sidewall. Tire air pressure may require re-adjustment within these
pressure limits to accommodate the additional weight of the snowplow
installation.
• Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your authorized dealer for
additional information.
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.
