2021 LINCOLN NAVIGATOR four wheel drive

It may be safer to stay on the shoulder of the
road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly.
It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than attempt
a sudden return to the road which could
cause your vehicle to slide sideways out of
control or roll over. Remember, your safety
and the safety of others should be your
primary concern.
If Your Vehicle Gets Stuck
WARNING: Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow 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 or
damage to the transmission could occur.
Note: Do not rock your vehicle for more than
a minute or damage to the transmission and
tires may occur or the engine could
overheat.
Emergency Maneuvers
In an unavoidable emergency where a
sudden sharp turn must be made, remember
to avoid over-driving your vehicle, for
example, turn the steering wheel only as
rapidly and as far as required to avoid the
emergency. Excessive steering can result in
loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are
required. Avoid abrupt steering, acceleration
and braking. This could result in an increased
risk of vehicle roll over, loss of vehicle control
and personal injury. Use all of the available
road surface to bring your 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 such as from concrete to gravel,
there may be a change in the way your
vehicle responds to a maneuver, for
example, steering, acceleration or braking.
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 excessive wheel slip.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could 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 could be
limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal when slowly moving.
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive 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.
If the transmission, transfer case or front axle
are submerged in water, their fluids should
be checked and changed, if necessary.
If the front or rear axle is submerged in water,
the axle lubricant should be replaced.
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 could
damage the vehicle.
Driving on Hilly or Sloping Terrain
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 your vehicle stalls, do not try to turn around
because this could cause vehicle roll over.
It is better to reverse back 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. Disengage overdrive
or move the transmission selector lever 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 your vehicle.
If your vehicle has anti-lock brakes, apply the
brakes steadily. Do not pump the brakes.

Note:
Avoid driving crosswise or turning on
steep slopes or hills.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you will use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer.
Driving on Snow and Ice WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle. Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide when driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and ice.
Apply the accelerator slowly and steadily
when starting from a full stop.
Avoid sudden braking. Although a four-wheel
drive vehicle may accelerate better than a
two-wheel drive vehicle in snow and ice, it
does not stop any faster as braking occurs
at all four wheels. Do not become
overconfident in any road condition.
Make sure you allow sufficient distance
between you and other vehicles for stopping.
Drive slower than usual and consider using
one of the lower gears. In emergency
stopping situations, apply the brake steadily.
Do not pump the brake pedal. See Hints on
Driving With Anti-Lock Brakes
(page 242).
Note: Excessive tire slippage can cause
transmission damage. Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and tested
to provide predictable performance whether
loaded or empty. For this reason, we strongly
recommend that you do not make
modifications such as adding or removing
parts, for example, lift kits or stabilizer bars,
or by using replacement parts not equivalent
to the original factory equipment.
We recommend that you use caution when
your vehicle has either a high load or device
such as a ladder or luggage racks. Any
modifications to your vehicle that raise the
center of gravity could cause your vehicle to
roll over when there is a loss of vehicle
control.
Failure to maintain your vehicle correctly
could void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely affect
you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off-road usage.

•
NORMAL – For everyday driving. This
mode is a perfect balance of excitement,
comfort and convenience.
• EXCITE – For aggressive on-road driving.
This mode increases throttle response,
provides a sportier steering feel, along
with quicker shifting. The suspension
stiffens, with an emphasis on handling
and control. The transmission also holds
gears longer, helping your vehicle
accelerate faster when shifting gears.
• CONSERVE
– Enables efficient and
responsible driving. It helps deliver
maximum fuel efficiency and increases
driving range.
• NORMAL 4A
– For general on-road
driving. Use this mode on normal firm
surfaces such as dry or wet pavement
and hard packed dirt or gravel roads.
Delivers power to all four wheels, as
required. •
SLIPPERY
– For less than ideal road
conditions, such as snow or ice covered
roads. Slippery mode inspires confidence
without taking away from driving
pleasure. Slippery mode lowers throttle
response and optimizes shifting for
slippery surfaces.
• DEEP CONDITIONS
– Used for crossing
terrain that has deformable deep, rutted
surfaces such as mud, deep snow or
deep sand. Do not use on dry, hard
surfaced roads.
• SLOW CLIMB
– Used when you need
extra power, such as when climbing
steep grades, going through deep sand
or pulling a boat out of a launch ramp.
Do not use on dry, hard surfaced roads.
Slow Climb mode puts you in 4x4 Low
drive line settings.
Note: Slow Climb is only available on
vehicles with 4x4 and a two-speed transfer
case. Note:
The system has diagnostic checks that
continuously monitor the system for proper
operation. Certain drive modes are not
available based on gear shifter position. If
a mode is unavailable due to a system fault
or change in gear shifter position, the mode
defaults to
NORMAL.

Distance D
The horizontal distance from the bumper to
the center of the trailer axle (single axle
trailers), or the center of the axles (trailers
with dual axles or more).
Note:
If the distance ends in anything less
than one half of an inch, round down to the
current whole inch. If a distance ends in one
half or greater of an inch, round up to the
next whole inch. For example, 12.3 in
(31.12 cm) would be rounded down to 12 in
(30.48 cm). 12.5 in (31.75 cm) would be
rounded up to 13 in (33 cm).
Step 5: Enter Measurements Using the
Information Display
Using the recorded measurements, enter the
required data into the system. Follow the on
screen prompts to enter each of the
measurements taken in step 4. When all four
distances have been entered, a confirmation
display will appear. Check the values are
correct before proceeding, or go back to
change any if required. Step 6: Confirming the Sticker Location
Check the rear view camera display to see
if the sticker is identified by the system and
marked with a red circle.
Confirm that the red circle is correctly located
over the sticker image in the display. The on
screen prompt will ask you to confirm this.
Note:
If the system cannot locate the sticker
try cleaning the camera lens, and also make
sure the sticker is within the green zone as
indicated in step 3.
Calibrating the System
To complete setup, drive your vehicle
straight forward between 4 mph (6 km/h) and
24 mph (39 km/h)
following the on screen
prompt.
Note: Check your measurements to make
sure you measured from the correct points.

or All-Terrain) or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire label
or Safety Compliance label for limitations
when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note:
Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to rise
above the bottom edge of the rear
bumper.
• Do not allow waves to break higher than
6 in (15 cm)
above the bottom edge of
the rear bumper. Exceeding these limits may allow water to
enter vehicle components:
•
Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime the
rear axle has been submerged in water.
Water may have contaminated the rear axle
lubricant, which is not normally checked or
changed unless a leak is suspected or other
axle repair is required.
