Avoid side-slopes if possible, otherwise, walk the hill to examine for any problems that might present themselves, such as holes, rocks, fallen trees, wet slippery grass and mud, snow and ice, that could lead to a roll over. Then proceed with caution.
If there is no escape route, it’s probably too dangerous to drive.
Your maximum tilt angle is 40 degrees. Less if you are ‘lifted.’

• The side slope being traversed could slip from under the vehicle. This is because the weight of the vehicle is transferred to its low side, putting most of the pressure on the two lower tyres instead of being evenly distributed over the four tyres.
• If the hill is wet or muddy fit chains. If it is rocky, try placing the sidewall of the tyres against the rocks to help prevent sliding.
• If the side slope is slippery, do not engage the axle lockers because they will tend to walk the vehicle sideways down the slope. This is because all wheels are rotating at the same speed. When not engaged, one wheel is ‘static’ and the other is rotating. The ‘static’ one will act as an anchor or stabiliser that will keep the rig from slipping sideways.
• When on these side slopes, let the vehicle idle across, giving the tyres a chance to dig in and get the best traction.
• Have all passengers’ change seating to the uphill side.

• If the vehicle begins to slip sideways, immediately steer downhill.
• On facing downhill, immediately engage diff and axle locks!

• If you are faced with a dangerous situation and progress forward is the only option, find an anchor point uphill (tree, large rock etc), and in front of the vehicle, and winch along with the gear box in neutral. Without the wheels driving there is less risk of sliding sideways.

• Side slopes beneath water are particularly hazardous and should be checked out before driving wherever possible. 1st gear, low, diff locks and axle locker engaged. Proceed as slowly as possible.

A problem with “lockers” is the tendency of a locked differential to drive the vehicle sideways if traveling across a slanted surface, especially if the surface is slippery. Gravity is pulling the vehicle sideways down the slope, and the two locked wheels rotating together act like a giant corkscrew, driving the end that’s locked down the hill. If driving across a side-hill on a loose or slippery surface don’t use lockers.
