2020 LINCOLN NAUTILUS overheating

HEATED STEERING WHEEL (IF
EQUIPPED)
Switch the heated steering wheel on and off
using the touchscreen. Touch the button to switch the
heated steering wheel on and off.
Note: You can use the heated steering
wheel only when the engine is running.
Note: The system uses a sensor and is
designed to control the temperature of the
steering wheel and to prevent it from
overheating.
Note: In warm temperatures, the steering
wheel quickly reaches its maximum
temperature and the system reduces the
current to the heating element. This could
cause you to think that the system has
stopped working but it has not. This is
normal. HORN

3. Press and hold the function button you
want to program for 2 seconds, then
release. Repeat this step. Depending on
your brand of garage door opener, you
may need to repeat this sequence a third
time. Gate Operator / Canadian Programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit) after
several seconds of transmission – which may
not be long enough for HomeLink to pick up
the signal during programming. Similar to
this Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
Note:
If programming a garage door opener
or gate operator, it is advised to unplug the
device during the “cycling” process to
prevent possible overheating.
1. Press and release, every two seconds,
your hand-held transmitter until the
HomeLink indicator light changes to a
rapidly blinking or continuously on light.
2. Release the hand-held transmitter button.
3. Continue programing HomeLink. See In-Vehicle Programming, Step 4
.
Erasing the Function Button Codes
Note: You cannot erase individual buttons. 1. Press and hold the outer two function
buttons simultaneously for approximately
10 seconds until the indicator light above
the buttons flashes rapidly.
2. When the indicator light flashes, release
the buttons. You erased the codes for all
buttons.
Reprogramming a Single Button
To program a device to a previously trained
button, follow these steps:
1. Press and hold the desired button. Do NOT release the button.

USING ALL-WHEEL DRIVE
All-wheel drive uses all four wheels to power
the vehicle. This increases traction, enabling
you to drive over terrain and road conditions
that a conventional two-wheel drive vehicle
cannot. The AWD system turns on when
needed and does not require input from you.
Note:
The AWD feature gives your vehicle
some limited off-road capabilities in which
driving surfaces are relatively level,
obstruction-free and otherwise similar to
normal on-road driving conditions. Operating
your vehicle under other than those
conditions could subject the vehicle to
excessive stress that might result in damage
that your vehicle warranty does not cover.
Note: A warning message appears in the
information display when an AWD system
fault is present. See Information Messages
(page 122). An AWD system fault causes the
AWD system to default to front-wheel drive
only mode. When this warning message
displays, have your vehicle serviced at an
authorized dealer Note:
A warning message appears in the
information display if the AWD system has
overheated. See Information Messages
(page 122). This condition may occur if you
operate the vehicle in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal AWD function as
soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10
minutes. After you restart the engine and the
AWD system adequately cools, the warning
message turns off and normal AWD function
returns.
Do not use a spare tire of a different size
other than the tire provided. If the mini-spare
tire is installed, the AWD system may disable
automatically and enter front-wheel drive
only mode to protect driveline components.
A warning in the information display appears,
indicating that the system is in front-wheel
drive only mode. See Information Messages
(page
122). If there is a warning message in
the information display from using the spare
tire, this indicator should turn off after
reinstalling the repaired or replaced normal
road tire and cycling the ignition off and on.
We recommend that you reinstall the repaired or replaced road tire as soon as
possible. Major dissimilar tire sizes between
the front and rear axles could cause the AWD
system to stop functioning and default to
front-wheel drive or damage the AWD
system.
Driving in Special Conditions with All-
Wheel Drive (AWD)
AWD vehicles are ready to drive on sand,
snow, mud and rough roads and have
operating characteristics that are somewhat
different from conventional vehicles, both on
and off the highway.
Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
199

(If Equipped)

abrupt steering, acceleration or braking
which could result in an increased risk of
loss of vehicle control, vehicle rollover
and personal injury. Use all available road
surface to return the vehicle to a safe
direction of travel.
• In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
• If your vehicle goes from one type of
surface to another, for example, from
concrete to gravel, there may be a
change in the way the vehicle responds
to a maneuver, such as, steering,
acceleration or braking. Again, avoid
these abrupt inputs.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid spinning the wheels. Driving your AWD in deep sand may cause
the AWD system to overheat. After the
system cools down, normal AWD function
returns.
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
you may need assistance 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 improves
when you move your vehicle slowly when
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,
have the power transfer unit (PTU) or rear
axle serviced by an authorized dealer. “Tread Lightly” is an educational program

”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. Whenever driving on a hill,
determine beforehand the route you want
to use. Do not drive over the crest of a hill
without seeing what conditions are on the
other side. Do not drive in reverse (R) over
a hill without the aid of an observer.
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If you do stall out, do not try to turn around
because you might roll over. It is better to
back down to a safe location. Apply just enough power to the wheels to
climb the hill. Too much power causes the
tires to slip, spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral (N); instead,
disengage overdrive or manually shift to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could lose
control. The front wheels have to be turning
in order to steer the vehicle.
