Automatic tire chains are optional. See Fig. for an example of the automatic tire chain switch. An LED in the switch illuminates when the tire chains are activated.

Important: The tire chains must be engaged and disengaged while moving, and before slippage occurs.

  1. The tire chains must be engaged from the dash mounted switch when traveling between 5 to 25 mph (8 to 40 km/h). If the tire chains need to be engaged from a standstill, spin the tires at 5 mph (8km/h) before engaging the chains. This will prevent the chains from becoming tangled. Do not spin the tires too fast, as this will increase the time it takes to gain traction.
  2. When the tire chains are no longer needed, they must be disengaged when traveling between 5 to 30 mph (8 to 48 km/h).
  3. When approaching an icy grade and the tire chains have not been engaged, adjust speed to 25 mph (40 km/h) and engage the tire chains. Then, slowly regain and maintain speed.
