Adding A Snow Plow Or Similar Equipment - GMC Envoy XL 2003 Owner's Manual

Overload Protection
The air suspension system is equipped with overload
protection. Overload protection is designed to protect the
air suspension system, and it is an indicator to the
driver that the vehicle is overloaded. When the overload
protection mode is on, it will not allow damage to the
air compressor. However, do not overload the vehicle.
See Loading Your Vehicle on page 4-48.
If the suspension remains at a low height, the rear axle
load has exceeded GAWR (Gross Axle Weight
Rating). When the overload protection mode is activated,
the compressor operates for about 30 seconds to one
minute without raising the vehicle depending on the
amount of overload. This will continue each time
the ignition is turned on until the rear axle load is
reduced below GAWR.

Indicator Light
The indicator light on the inflator switch in the rear
passenger compartment also serves as an indicator
internal system error. If the indicator light is flashing
without the load leveling function or the inflator beins
active, turn off the ignition. The next day turn on
the ignition and check the indicator light. The vehicle
can be driven with the light flashing, but if it is you
should have the vehicle serviced as soon as possible.

Equipment
Your vehicle was neither designed nor intended for a

Notice: Adding a snow plow or similar equipment
to your vehicle can damage it, and the repairs
