214 All-Wheel Drive (If Equipped)
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.
Mud and Water
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.
When driving through water, determine the depth; avoid water higher
than the bottom of the wheel rims (for cars) or the bottom of the hubs
(for trucks) (if possible) and proceed slowly. If the ignition system gets
wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even AWD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
Note: Driving through deep water may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant and
PTU (power transfer unit) lubricant should be checked and changed if
necessary.
Service and the Bureau of Land Management in encouraging you to help
preserve our national forest and other public and private lands by
"treading lightly."
Driving on Hilly or Sloping Terrain
Note: Avoid driving crosswise or turning on steep slopes or hills. A
danger lies in losing traction, slipping sideways and possibly rolling over.
