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)
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.
227
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Four-Wheel Drive
(If Equipped)
Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary.
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 try to drive
straight up or straight down.
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 can 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. 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 turnaround
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 can cause
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.
Note:
If your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes. DRIVING ON SNOW AND ICE
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 while 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
can accelerate better than a two-wheel drive
vehicle in snow and ice, it cannot stop any
faster as braking occurs at all four wheels.
Do not become overconfident as to road
conditions.
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 Anti-Lock
Braking System Limitations (page 233).

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.

HOW DOES STABILITY CONTROL
WORK
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo speakers may interfere with and
adversely affect the electronic stability
control system. Reducing the effectiveness
of the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the laws
of physics. It's always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator's
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death.
WARNING:
You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.
If a driving condition activates either the
stability control or traction control you may
experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power. The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control enhances your
vehicle
’s ability to prevent skids or lateral
slides by applying brakes to one or more of
the wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
Roll stability control enhances your vehicle ’s
ability to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
Curve Control
Curve control enhances your vehicle ’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
control operates by reducing engine power
and, if necessary, applying brakes to one or
more of the wheels individually.

PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care and
attention. Failure to take care may result
in a crash. WARNING:
Traffic control systems,
fluorescent lamps, inclement weather, air
brakes, external motors and fans may
affect the correct operation of the sensing
system. This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects, particularly
those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects when
your vehicle is moving at parking speeds.
To help avoid personal injury you must
take care when using the parking aid
system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all limit
sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts. When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note:
Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer hitches,
bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt. If the
sensors are covered, the system's accuracy
can be affected.
Do not clean the sensors with sharp objects.
Note: When using a programmed MyKey,
you cannot switch the parking aids off. See
MyKey™
(page 82).
