2022 LINCOLN NAVIGATOR cooling

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 HILL DESCENT CONTROL
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.
HOW DOES HILL DESCENT
CONTROL WORK
Hill descent control can maintain vehicle
speeds on downhill slopes between
2–20 mph (3–32 km/h). Above 20 mph
(32 km/h), the system remains on but the
descent speed cannot be set or maintained.
Note: The system does not function below
2 mph (3 km/h)
.
The system requires a cool down interval
after a period of sustained use. Hill descent
control provides a warning in the message
center and a tone sounds when the system
is about to disengage for cooling. At this
time, manually apply the brakes as needed
to maintain descent speed. Note:
The amount of time that the system
can remain active before cooling varies with
conditions.
HILL DESCENT CONTROL
PRECAUTIONS WARNING:
The system does not
control speed in low traction conditions or
extremely steep slopes. 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 personal injury. WARNING:
Hill descent control
cannot control descent in all surface
conditions and circumstances, such as ice
or extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of
vehicle control, crash or serious injury. WARNING:
The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake and shift the transmission into park
(P) for automatic transmission or first gear
for manual transmission.
SWITCHING HILL DESCENT
CONTROL ON AND OFF Press the button on the instrument
panel. A light illuminates and a
tone sounds when the system is
active.
SETTING THE HILL DESCENT
SPEED
To increase or decrease the descent speed,
press the accelerator or brake pedal, or use
the SET + and SET - buttons on the steering
wheel. Once you reach the preferred speed
remove your feet from the pedals.

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).

and Specification (page 471).
CHECKING THE COOLANT
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 528). Note:
Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between
-29°F (-34°C) and -35°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant WARNING:
Keep your hands and
clothing clear of the cooling fan.

2022 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202109, First-Printing Maintenance

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. WARNING:
Do not add engine
coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal injury. WARNING:
Do not add coolant
further than the MAX mark. WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. WARNING:
Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Note: Automotive fluids are not
interchangeable.
It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system.
See Capacities
and Specifications (page 469). Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and could void
the vehicle Warranty. Note:
If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with deionized or distilled
water.
See Capacities and Specifications
(page 469). Using water that has not been
deionized may contribute to deposit
formation, corrosion and plugging of the
small cooling system passageways.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add enough prediluted coolant to reach
the correct level.
Note: We do not recommend the use of
recycled coolant.
3. Replace the coolant reservoir cap. Turn the cap clockwise until it contacts the
hard stop.
4. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, repeat step 2.

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.
