STARTING AND OPERATING 251 Standing Water Avoid driving in standing water deeper than 20 inches, and reduce speed appropriately to minimize wave effects. Maximum speed in 20 inches of water is less than 5 mph (8 km/h). Maintenance After driving through deep water, inspect your vehicle fluids and lubricants (engine oil, transmission oil, axle, transfer case) to assure the fluids have not been contaminated. Contaminated fluid (milky, foamy in appearance) should be flushed/changed as soon as possible to prevent component damage. Driving In Snow, Mud and Sand In heavy snow, when pulling a load, or for additional control at slower speeds, shift the transmission to a low gear and shift the transfer case to 4L or 4LO if necessary. Refer to "Four-Wheel Drive Operation" in this section. Do not shift to a lower gear than necessary to maintain headway. Over-revving the engine can spin the wheels and traction will be lost. Avoid abrupt downshifts on icy or slippery roads, because engine braking may cause skidding and loss of control. Hill Climbing NOTE: Before attempting to climb a hill, determine the conditions at the crest and/or on the other side. Before climbing a steep hill, shift the transmission to a lower gear and shift the transfer case to 4L or 4LO. Use first gear and 4L or 4LO for very steep hills. If you stall or begin to lose headway while climbing a steep hill, allow your vehicle to come to a stop and immediately apply the brakes. Restart the engine and shift to R (Reverse). Back slowly down the hill allowing the compression braking of the engine to help regulate 5
