Traversing a slope
Survey the slope area on foot, especially the area where you intend exiting the slope.
Don't deflate the tyres too far, to avoid the risk of unseating them.
Never trust an inclinometer.
Never use differential locking.
Tackle the slope in low ratio 1st gear.
Turn the front wheels slightly into the slope, so as to progress crabwise.
If you start to slide backwards, immediately turn the front wheels towards the base of the slope.
