2020 LINCOLN NAVIGATOR Owners Manual

Shifting to or from 4L - 4X4 LOW
Note:
4L mode is not intended for use on dry
pavement.
1. Bring the vehicle to a rolling speed of 3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Rotate the drive mode knob to desired mode.
The information display shows a message
indicating a 4X4 shift is in progress. The
information display shows the system mode
selected. If any of the previous shift
conditions are not present, the shift does not
occur and the information display shows the
information guiding the driver through the
proper shifting procedures. If the previous
conditions are not satisfied in 30 seconds,
the system reverts back to the previous 4WD
mode or drive mode. If
Shift Delayed Pull Forward displays in the
information display, transfer case gear tooth
blockage is present. To alleviate this
condition, place the transmission in a forward
gear, move the vehicle forward
approximately
5 ft (2 m), and shift the
transmission back to neutral (N) to allow the
transfer case to complete the range shift.
Operating 4WD Vehicles with Spare or
Mismatched Tires
On four-wheel drive vehicles, the size of the
spare tire can affect the 4X4 system. If there
is a significant difference between the size
of the spare tire and the remaining tires, you
may have limited four-wheel drive
functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
• Exceed
50 mph (80 km/h) with a 4WD
mode turned on.
• Turn on a 4WD mode unless the vehicle
is stationary.
• Use a 4WD mode on dry pavement. Use of a dissimilar spare wheel and tire
assembly may lead to impairment of the
following:
•
Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
How Your Vehicle Differs from Other
Vehicles WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.

(If Equipped)

Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough terrain
without getting hung up or damaging
underbody components.
The differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car.
Maintain steering wheel control at all times,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the area.
To maintain steering and braking control of
your vehicle, you must have all four wheels
on the ground and they must be rolling, not
sliding or spinning.
Driving Off-Road with Truck and Utility
Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive when
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern.
Note: Your vehicle may have a front air dam.
Due to low ground clearance, you can
damage it when taking your vehicle off-road.
You can take the air dam off by removing
the bolts that secure it.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud and
rough terrain and have operating
characteristics that are somewhat different
from conventional vehicles, both on and off
the road.
Power is supplied to all four wheels through
a transfer case. On four-wheel drive vehicles,
the transfer case allows you to utilize
different 4X4 modes when necessary.
Information on transfer case operation and
shifting procedures can be found in this chapter and the Driving Aids chapter.
Information on transfer case maintenance
can be found in the Maintenance chapter.
You should become thoroughly familiar with
this information before you operate your
vehicle.
Four-wheel drive, when you select a
4X4-capable drive mode, it 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.

Basic Operating Principles
•
Do not use SLIPPERY, DEEP
CONDITIONS or SLOW CLIMB on dry,
hard surfaced roads. Doing so produces
excessive noise, increases tire wear and
may damage drive components. The 4X4
system in these modes is only intended
for consistently slippery or loose
surfaces.
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• When driving your vehicle on surfaces
made slippery by loose sand, water,
gravel, snow or ice, proceed with care.
If Your Vehicle Leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
When your vehicle speed has been reduced
ease your vehicle back onto the road. Do
not turn the steering wheel sharply when
returning your vehicle to the road. 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.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, damage to the transmission and
tires may occur or the engine may overheat. 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.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your vehicle
(i.e. 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 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.
232
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Four-Wheel Drive
(If Equipped)

If your vehicle goes from one type of surface
to another (i.e. from concrete to gravel) there
may be a change in the way your vehicle
responds to a maneuver (i.e. 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
Note:
Driving through deep water may
damage the vehicle. If you must drive through high water, drive
slowly. Traction or brake capability may 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 moving slowly.
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even 4X4 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.
Driving on Hilly or Sloping Terrain
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.
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.
233
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Four-Wheel Drive (If Equipped)

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.
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. Note:
Excessive tire slippage can cause
transmission damage.
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 238).

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 (i.e. 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
(i.e. ladder or luggage racks). Any
modifications to your vehicle that raise the
center of gravity may cause your vehicle to
roll over when there is a loss of vehicle
control.
Failure to maintain your vehicle correctly may
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.

LIMITED SLIP DIFFERENTIAL (IF
EQUIPPED)
The Electronic Limited Slip Differential (eLSD)
system directs torque, enabling the vehicle
to drive over terrain and road conditions that
a conventional axle cannot. The system is
active at all times and requires no input from
the driver.
Note: If your vehicle is not at optimal
operating conditions or a system fault is
present, a warning may be displayed in the
instrument cluster. Depending on the
warning, your vehicle may need to be
serviced. You can find more information
regarding the system information messages
in the Information Displays chapter.
See
Information Messages (page 138).
Spare Tire
If your vehicle has an Electronic Limited Slip
Differential, do not use a spare tire of a
different size than the tire provided. If a spare
tire is installed, a message may appear,
indicating the system has disabled
automatically or reduced function to prevent system overheat and damage. It is
recommended to reinstall the repaired or
replaced road tire as soon as possible. When
the road tire is replaced, the system will
resume normal operation on the next key
cycle.
Trailer Towing
The Electronic Limited Slip Differential
enhances vehicle stability during trailer tow
operation. During high demand trailering
events, such as steep slopes, high speeds
or with a spare tire, the system may provide
a warning in the instrument cluster and
reduce function or enter a temporarily
disabled state. To resume normal function,
stop the vehicle in a safe location and allow
the unit to adequately cool. Once the system
has reached normal operating temperatures,
system function will be restored and the
Electronic Limited Slip Differential Restored
message will be displayed.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 400). See
Warning Lamps and
Indicators (page 128).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement.If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
can reduce stopping distances in critical
situations.Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you switch the ignition on. If
the light does not illuminate during
start up, remains on or flashes, the anti-lock
braking system may be disabled. Have the
system checked by an authorized dealer. If
the anti-lock brake system is disabled,
normal braking is still effective. If the brake warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
It also illuminates momentarily when you
switch the ignition on to confirm the lamp is
functional. If it does not illuminate when you
switch the ignition on, or begins to flash at
any time, have the system checked by an
authorized dealer.
