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).

(If Equipped)

Your vehicle may have a temporary or
conventional spare tire. A temporary spare
tire is different in diameter or width,
tread-type, 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.
When towing a trailer:
•
Obey country specific regulations for
towing a trailer.
• Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled
50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off when you are towing on
long, steep slopes. •
Shift to a lower gear when driving down
a long or steep hill. Do not continuously
apply the brakes, as they may overheat
and become less effective.
• If your transmission has Grade Assist or
Tow/Haul, use this feature when towing.
This provides engine braking and helps
eliminate excessive transmission shifting
for optimum fuel economy and
transmission cooling.
• Your vehicle has AdvanceTrac with roll
stability control. When towing a trailer,
additional loads could cause the
AdvanceTrac system to engage during
cornering maneuvers. Reduce cornering
speeds to make sure that you can
maintain control of the vehicle and trailer
if the AdvanceTrac system engages. •
Allow more distance for stopping with a
trailer attached. Anticipate stops and
gradually brake.
• Avoid parking on a slope. However, if
you must park on a slope, turn the
steering wheel to point your vehicle tires
away from traffic flow, set the parking
brake, place the transmission in park (P)
and place wheel chocks in front and back
of the trailer wheels.
Note: Chocks are not included with your
vehicle.
LAUNCHING OR RETRIEVING A
BOAT OR PERSONAL
WATERCRAFT
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.

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See Instrument
Cluster Overview (page 141).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually. 1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Cooling
System Capacity and Specification
(page
473).
5. Have your vehicle checked as soon as possible.
COLD WEATHER PRECAUTIONS
The functional operation of some
components and systems can be affected at
temperatures below approximately
-13°F
(-25°C). 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.
On ice and snow, you should drive more
slowly than usual. Your vehicle has a four
wheel anti-lock brake system, do not pump
the brake pedal.
See Anti-Lock Braking
System Limitations (page 233).

DRIVING THROUGH MUD AND WATER
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even all-wheel drive and four-wheel
drive vehicles can lose traction in mud. If
your vehicle slides, 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 residue can cause an imbalance that
could damage drive components.
Note:
If your vehicle gets stuck in mud, it
could 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, as
damage to the transmission could occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires could occur or the engine could
overheat. Water
If you must drive though deep water, drive
slowly. The water could limit traction or brake
capability. See Driving Through Shallow
Water (page 387).
When driving though water, determine the
depth and avoid water higher than the center
of the wheel.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
quickly as dry brakes. Apply light pressure
to the brake pedal while slowly moving the
vehicle to dry the brakes.
Note: Driving through deep water could
cause damage to the transmission. If the
front or rear axle is submerged in water,
have the axle lubricant and power transfer
unit lubricant checked and changed if
necessary. DRIVING ON HILLY OR SLOPING
TERRAIN WARNING: Extreme care should be
used when steering the vehicle in reverse
down a slope so as not to cause the
vehicle to swerve out of control.
Although natural obstacles could 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.

Apply just enough power to the wheels to
climb the hill. Too much power causes the
tires to slip, spin or lose traction, and you
could lose control of your vehicle. When
descending a steep hill, do not descend the
hill in neutral. Avoid sudden hard braking to
keep the front wheels rolling and to maintain
your vehicle's steering.
Note:
Your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes.
Note: If your vehicle gets stuck driving on
hilly or sloping terrain, it could 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, as
damage to the transmission could occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires could occur or the engine could
overheat. DRIVING IN SAND
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Steadily drive through the terrain. Apply the
accelerator slowly and avoid excessive
wheel slip. Do not drive your vehicle in deep
sand for an extended period of time. This
could overheat the system. A message
appears in the instrument cluster display.
Note:
If your vehicle gets stuck driving on
hilly or sloping terrain, it could 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, as
damage to the transmission could occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires could occur or the engine could
overheat DRIVING THROUGH SHALLOW
WATER WARNING: Do not attempt to cross
a deep or flowing body of water. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the front rocker
area of your vehicle.

If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location.
Service your vehicle as soon as possible.
Water alone, without engine coolant, can
cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute, as they can cause engine damage
from overheating or freezing:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant. Severe Climates
If you drive in extremely cold climates, you
may need to increase the coolant
concentration above 50%.
Note:
A coolant concentration of 60%
provides improved freeze point protection.
Coolant concentrations above 60% decrease
the overheat protection characteristics of
the coolant and could cause engine
damage.
If you drive in extremely hot climates, you
may need to decrease the coolant
concentration to 40%.
Note: A coolant concentration of 40%
provides improved overheat protection.
Coolant concentrations below 40% decrease
the overheat and corrosion protection
characteristics of the coolant and could
cause engine damage. Coolant Change WARNING: Do not dispose of coolant
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Change the coolant at specific mileage
intervals. Refer to the scheduled
maintenance information.
See Normal
Scheduled Maintenance (page 532).
Note: Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
420
2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Maintenance

How Fail-Safe Cooling Works
If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage. When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for use
during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury. Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine could
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider.
3. If this is not possible, wait for a short period of time for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.

Engine Coolant Temperature
Management (If Equipped)
WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the vehicle
may not be able to accelerate with full
power until the coolant temperature
reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display. You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1.
Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N). 2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
ENGINE AIR FILTER
CHANGING THE ENGINE AIR FILTER WARNING:
To reduce the risk of
vehicle damage and personal burn injuries,
do not start your engine with the air
cleaner removed and do not remove it
while the engine is running.
