You can also use the 1st and 2nd gear to decrease wheelspin especially when getting out of deep snow or slippery mud. Too much wheelspin decreases traction in icy or muddy conditions.

Going to Baguio ok lang sa "drive" position i think. Gamitin mo lang yung gears 1, 2, 3 kung very steep talaga ang road and you have a very heavy load.
