As you approach a hill, consider its grade or steepness.

Determine if it is too steep. Look to see what the traction is on the hill side trail. Is the trail straight up and down?

What is on top and the other side? Are there ruts, rocks, branches or other obstacles on the path? Can you safely recover the vehicle if something goes wrong? If everything looks good and you feel confident, shift the transmission into a lower gear with 4L (Low) engaged, and proceed with caution, maintaining your momentum as you climb the hill.
