Lincoln 2013 MKZ Owner's Manual page 177

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.
E142667
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.
All-Wheel Drive
(If Equipped)
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 AWD
PTU (Power Transfer Unit) lubricant
should be checked and changed if
necessary.
