2023 LINCOLN AVIATOR Brake maintenance mode

Note:The driver and front passenger
warnings switch on and off independently.
When you perform this procedure for one
seating position, do not buckle the other
position as this terminates the process.
Read Steps 1 - 4 before starting the
procedure.
Make sure that:
• You set the parking brake.
• The transmission is in park (P).
• The ignition is off.
• You close all vehicle doors.
• You unbuckle the driver and front
passenger seatbelts.
1. Switch the ignition on. Do not start the
engine.
2. Wait until the seatbelt warning lamp turns
off (about one minute). After Step 2, wait
an additional five seconds before
proceeding with Step 3. Once you start
Step 3, you must complete the procedure
within 60 seconds.3. For the seating position you are switching
off, buckle then unbuckle the seatbelt
three times at a moderate speed, ending
in the unbuckled state. After Step 3, the
seatbelt warning lamp turns on.
4. When the seatbelt warning lamp is on,
buckle then unbuckle the seatbelt. After
Step 4, the seatbelt warning lamp flashes
for confirmation.
• This switches the feature off if it is
currently on.
• This switches the feature on if it is
currently off.
CHILD RESTRAINT AND SEATBELT
MAINTENANCE
Inspect the vehicle seatbelts and child safety
seat systems periodically to make sure they
work properly and are not damaged. Inspect
the vehicle and child restraint seatbelts to
make sure there are no nicks, tears or cuts.
Replace if necessary. All vehicle seatbelt
assemblies, including retractors, buckles,
front seatbelt buckle assemblies, buckle
support assemblies (slide bar-if equipped),shoulder belt height adjusters (if equipped),
shoulder belt guide on seat backrest (if
equipped), child safety seat LATCH and
tether anchors, and attaching hardware,
should be inspected after a crash. Read the
child restraint manufacturer's instructions for
additional inspection and maintenance
information specific to the child restraint.
We recommend that all seatbelt assemblies
in use in vehicles involved in a crash be
replaced. However, if the crash was minor
and an authorized dealer finds that the belts
do not show damage and continue to
operate properly, they do not need to be
replaced. Seatbelt assemblies not in use
during a crash should also be inspected and
replaced if either damage or improper
operation is noted.
Properly care for seatbelts. See Vehicle
Care (page 421).

Information Displays

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 may
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.
407
Maintenance

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.AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 579).
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.

lubrication of your jack is required over the
service life of your vehicle.
1. Park on a level surface, set the parking
brake and switch on the hazard flashers.
2. Apply the parking brake, place the
transmission in park (P) and turn the
engine off.
3. If your vehicle has air suspension, use
the touch screen to switch on the Air
