[Off Road Driving] Sand
HARD SAND - High range 1st, 2nd or 3rd.
* SOFT SAND - Lower tyre pressures in the range of 15-22 psi. Low range 3rd, 4th or 5th. Engage Diff lock and axle lockers (if fitted).
Momentum - not speed!
Follow existing wheel tracks if there are any.
Ascend sand hills with momentum, swing the steering wheel from side to side if need be. If stalled going up, reverse straight back down in gear, never coast down.
Descend sand hills slowly, low range 2nd, straight down and do not use the brakes as this could cause a roll over. If the vehicle noses in, change to low 3rd, with your foot on the brake and accelerator at the same time. If bogged, try rocking the vehicle backwards and forwards and try to drive out by alternating between 1st and reverse gears. If all else fails, lower the tyre pressure to 6 psi.
In soft sand, the rear lockers will tend to want to steer the vehicle straight even though you are trying to turn. If this occurs, disengage the lockers until the turn is completed.
Dont fight the steering wheel, rather grip it loosely and let the sand do the steering.
Never use the brakes except in an extreme emergency. Braking will bog the vehicle. Allow the sand to stop the vehicle.
Only a small section of desert sand is soft, so use normal tyre pressure.
If the tyre pressure is decreased by 25% (25 psi), speed should not exceed 48 km/h (30 m/h).
If the tire pressure is decreased by 40% (20 psi), speed should not exceed 19 km/h (12 m/h).
Exceeding these speeds at low pressure can cause the tires to leave the rim.
The optimum tyre pressure is around 15 psi.
Watch out for changes in the colour of thesand on the road/track ahead as this almost always signals a change in the consistency of the track.
When stopping on deep sand, depress the clutch, if manual transmission, or select neutral if automatic, and allow the vehicle to coast to a stop.
Avoid the soft sand at the base of most dunes and gullies when stopping.
When turning, make the turn as wide as possible to reduce the chance of bogging. The front wheels act more like a rudder in sand and turning too sharp has a similar effect to suddenly applying the brakes.
No hand signals, driver playing with his transfer Knob.
