HOW DOES FOUR-WHEEL DRIVE
WORK
Using the 1-Speed Automatic Four-
Wheel Drive System
The 1-speed automatic four-wheel drive
system utilizes an electronically controlled
on-demand 1-speed transfer case. This
system monitors various vehicle sensory
inputs to provide an increased level of
performance. This system offers the driver
two-wheel drive high, four-wheel drive auto
and four-wheel drive high as available modes
of operation via the selectable drive mode
switch. When four-wheel drive auto is
selected, the system continuously varies
power to the front wheels for optimum
performance for all on-road conditions. When
four-wheel drive high is selected, the system
provides power to the front and rear wheels
for use in off-road or slippery conditions such
as deep snow, sand or mud. There is further
information on driving in unique driving
conditions. See Driving Hints (page 384).
Using the 2-Speed Automatic Four-
Wheel Drive System
(If Equipped)
The 2-speed automatic four-wheel drive
system utilizes an electronically controlled
on-demand 2-speed transfer case. This
system monitors various vehicle sensory
inputs to provide an increased level of
performance. This system offers the driver
two-wheel drive high, four-wheel drive auto,
four-wheel drive high, and four-wheel drive
low as available modes of operation. When
four-wheel drive auto is selected, the system
continuously varies power to the front wheels
for optimum performance for all on-road
conditions. When either four-wheel drive high
or four-wheel drive low are selected with the
appropriate drive modes , the four-wheel
drive system provides electronically locked
power to the front and rear wheels for use
in off-road or slippery conditions such as
deep snow, sand or mud. Selecting slow
climb also provides additional gearing for
increased torque multiplication for conditions
like deep sand, snow, steep slopes, or pulling heavy objects.
See Slow Climb (page 296).
Additionally, the system is capable of
recreational flat towing by putting the
transfer case into neutral (N).
See
Recreationally Towing Your Vehicle (page
397).
There is further information on driving in
unique driving conditions. See Driving Hints
(page
384).
FOUR-WHEEL DRIVE
PRECAUTIONS 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.
223
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Four-Wheel Drive
(If Equipped)

WARNING: Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough terrain
without getting stuck or damaging
underbody components. The differences that
make your vehicle so versatile also make it
handle differently than an ordinary passenger
car. Always maintain steering wheel control,
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. 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.
Note:
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components.
FOUR-WHEEL DRIVE LIMITATIONS
Operating Four-Wheel Drive with a
Spare or Mismatched Tires
(If Equipped)
On four-wheel drive vehicles, the size of the
spare tire can affect the four-wheel drive
system. If there is a significant difference
between the size of the spare tire and the
remaining tires, you could have limited
four-wheel drive functionality. When driving
with the full-size dissimilar spare wheel and
tire assembly, we recommend that you do
not: •
Exceed
50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Use a four-wheel drive mode on dry
pavement.
Driving with the full-size dissimilar spare
wheel and tire assembly can limit four-wheel
drive functionality. You can experience the
following:
• Additional noise from the transfer case
or other drive components.
Use of a dissimilar spare wheel and tire
assembly can lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
Note: Your vehicle could have a front air
dam that can become damaged, due to
reduced ground clearance, when taking your
vehicle off-road. You can remove this air
dam by removing the eight bolts that secure
it.

(If Equipped)

Note:
Your vehicle could have side steps
that can become damaged, due to reduced
ground clearance, when taking your vehicle
off-road. Remove side steps before driving
your vehicle off-road.
SELECTING A FOUR-WHEEL DRIVE
MODE
To select a specific four-wheel drive mode
please select one of the desired drive
modes. For additional information. See
Selecting a Drive Mode (page 294).
Note: When shifting to and from four-wheel
drive information display will show shifting
in progress message indicating that the
system is in the process of making a shift.
Note: Do not perform this operation if the
rear wheels are slipping or while applying
the accelerator pedal.
If the system detects a fault, a warning
message appears in the information display.
See
Four-Wheel Drive – Information
Messages (page 229). Note:
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.
Shifting to or from Slow Climb (4L)
To select or exit SLOW CLIMB (4L):
1. Bring your vehicle to a speed of
3.1 mph
(5 km/h) or less.
2. Place the transmission in neutral (N).
3. Select SLOW CLIMB on the drive mode control switch.
The information display will display a
message indicating a four-wheel drive shift
is in progress. If any of the above shift
conditions are not present, the shift will not
occur and the information display will display
information guiding the driver through the
proper shifting procedures. If there is a
transfer case tooth blockage a message will display in the information display. To alleviate
this condition, place the transmission in a
forward gear, move your vehicle forward
approximately
4.9 ft (1.5 m), and shift the
transmission back to neutral (N) to allow the
transfer case to complete the range shift.
Note: You could hear some noise as the
system shifts or engages which is normal. If
the system detects a fault, a warning
message appears in the information display.
See
Four-Wheel Drive – Information
Messages (page 229).
FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
2H turns on when you select NORMAL or
CONSERVE. Two-wheel drive high is for
general on-road driving. Power is sent to the
rear wheels only.
Note: Two-wheel drive high can turn on or
off based on Drive Mode selection See Drive
Mode Control
(page 293).

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.
If your vehicle goes from one type of surface
to another (i.e. from concrete to gravel) there
can be a change in the way your vehicle
responds to a maneuver, i.e. steering,
acceleration or braking.
DRIVING IN 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.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Low gear operation can
maximize the engine and transmission
cooling capability.
Avoid driving at excessive speed. 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.
DRIVING THROUGH MUD AND WATER
WARNING: Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander. Mud
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. 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.
Water
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, test the brakes. Wet brakes
do not stop your vehicle as effectively as dry
brakes. Drying improves by applying light
pressure to the brake pedal while moving
slowly.

WHAT IS THE ELECTRONIC
LIMITED-SLIP DIFFERENTIAL
The electronic limited-slip differential 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 display in the
instrument cluster. Depending on the
warning, you may need to service your
vehicle. Operating the Electronic Limited-Slip
Differential with a Spare or Mismatched
Tires
If your vehicle has an electronic limited-slip
differential, do not use a spare tire of a
different size than the tire provided. If you
have a spare tire installed, a message may
appear indicating the system has disabled
automatically or reduced function to prevent
system overheat and damage. We
recommend you reinstall the repaired or
replaced spare tire as soon as possible.
When you replace the spare tire, the system
resumes 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
reaches normal operating temperatures,
system function restores and the electronic
limited-slip differential restored message
displays.

BRAKE PRECAUTIONS
WARNING: Driving your vehicle with
the warning lamp on is dangerous. A
significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when leaving a car wash or driving
from standing water to dry the brakes.
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, the stoplamps
could flash during heavy braking. Following
this the hazard warning flashers could also
turn on when your vehicle comes to a stop. ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM
LIMITATIONS
The anti-lock braking system does not
eliminate the risk of crash when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and travel further.
Maintain pressure on the brake pedal.
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. Move the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
LOCATING THE BRAKE FLUID
RESERVOIR
See
Under Hood Overview (page 415).
