drive shaft LINCOLN NAUTILUS 2021 Owners Manual

Avoid abrupt steering, acceleration and
braking changes. Abrupt changes could
increase the risk of vehicle roll over, loss of
vehicle control and personal injury. Use all
available road surfaces to bring your vehicle
under control.
In the event of an emergency stop, avoid
skidding and do not attempt any sharp
steering wheel movements.
Driving In Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Shift to a lower gear and drive steadily
through the terrain. Apply the accelerator
slowly and avoid excessive wheel slip. Do
not drive your vehicle in deep sand for an
extended period of time. This will cause the
system to overheat. A message appears in
the information display. See All-Wheel Drive
– Information Messages (page 217).
Note: If your vehicle gets stuck in sand, it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat.
Driving Through Mud and Water
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even all-wheel drive vehicles can lose
traction in mud. If your vehicle does slide,
steer in the direction of the slide until you
regain control of your vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
can cause an imbalance that could damage
drive components. Note:
If your vehicle gets stuck in mud, it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat.
Water
If you must drive through deep water, drive
slowly. The water could limit traction or brake
capability. See Driving Through Water (page
305
).
When driving through water, determine the
depth and avoid water higher than the center
of the wheel.
