DRIVING IN SPECIAL CONDITIONS
DRIVING THROUGH MUD AND WATER
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even all-wheel drive and four-wheeldrive vehicles can lose traction in mud. Ifyour vehicle slides, steer in the direction ofthe slide until you regain control of yourvehicle. After driving through mud, clean offresidue stuck to rotating driveshafts and tires.Excess residue can cause an imbalance thatcould damage drive components.
Note:If your vehicle gets stuck in mud, itcould be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature, asdamage to the transmission could occur.
Note:Do not rock your vehicle for more thana minute, as damage to the transmissionand tires could occur or the engine couldoverheat.
Water
If you must drive though deep water, driveslowly. The water could limit traction or brakecapability. See Driving Through ShallowWater (page 386).
When driving though water, determine thedepth and avoid water higher than the centerof the wheel.
Once through water, always try the brakes.Wet brakes do not stop your vehicle asquickly as dry brakes. Apply light pressureto the brake pedal while slowly moving thevehicle to dry the brakes.
Note:Driving through deep water couldcause damage to the transmission. If thefront or rear axle is submerged in water,have the axle lubricant and power transferunit lubricant checked and changed ifnecessary.
DRIVING ON HILLY OR SLOPINGTERRAIN
WARNING: Extreme care should beused when steering the vehicle in reversedown a slope so as not to cause thevehicle to swerve out of control.
Although natural obstacles could make itnecessary to travel diagonally up or down ahill or steep incline, you should try to drivestraight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you can use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.

Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, and youcould lose control of your vehicle. Whendescending a steep hill, do not descend thehill in neutral. Avoid sudden hard braking tokeep the front wheels rolling and to maintainyour vehicle's steering.
Note:Your vehicle has anti-lock brakes,apply the brakes steadily. Do not pump thebrakes.
Note:If your vehicle gets stuck driving onhilly or sloping terrain, it could be rocked outby shifting between forward and reversegears, stopping between shifts in a steadypattern. Press lightly on the accelerator ineach gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature, asdamage to the transmission could occur.
Note:Do not rock your vehicle for more thana minute, as damage to the transmissionand tires could occur or the engine couldoverheat.
DRIVING IN SAND
When driving over sand, try to keep all fourwheels on the most solid area of the trail. Steadily drive through the terrain. Apply theaccelerator slowly and avoid excessivewheel slip. Do not drive your vehicle in deepsand for an extended period of time. Thiscould overheat the system. A messageappears in the instrument cluster display.
