NOTE: During snowplow usage on vehicles equipped
with outside temperature display, the display may show
higher temperatures than the outside ambient tempera-
ture. The higher displayed temperature is due to blocked
or reduced airflow to the underhood ambient tempera-
ture sensor caused by the snowplow. In addition, on
vehicles equipped with Automatic Temperature Control
(ATC), it is suggested that the interior cabin temperature
be manually controlled should the system not perform as
desired while in automatic mode. Both the outside tem-
perature display and ATC operation will return to nor-
mal when the snowplow is removed.
General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer’s instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.
When plowing snow, to avoid transmission and drive-
train damage, the following precautions should be ob-
served.
• Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
• Vehicles with automatic transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
• Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.
