Sand

When driving over sand, try to keep all four wheels on the most solid area of the trail. Avoid reducing the tire pressures but shift to a lower gear and drive steadily through the terrain. Apply the accelerator slowly and avoid spinning the wheels.
When driving at slow speeds in deep sand under high outside temperatures, use a low gear or (L) when possible. L (Low) gear operation will maximize the engine and transmission cooling capability.
Under severe operating conditions, the A/C may cycle on and off to protect overheating of the engine.
Avoid excessive speed because vehicle momentum can work against you and cause the vehicle to become stuck to the point that assistance may be required from another vehicle. Remember, you may be able to back out the way you came if you proceed with caution.
