2021 LINCOLN AVIATOR heating

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 564).
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.
BRAKE FLUID CHECK
WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

conditions. Like any tire, summer tire
performance is affected by tire wear and
environmental conditions. If you must drive
in those conditions, we recommend using
Mud and Snow (M+S, M/S), All-season or
Snow tires.
Always store your summer tires indoors at
temperatures above 19°F (-7°C). The rubber
compounds used in these tires lose flexibility
and may develop surface cracks in the tread
area at temperatures below
19°F (-7°C). If the
tires have been subjected to 19°F (-7°C) or
less, warm them in a heated space to at least
41°F (5°C)
for at least 24 hours before
installing them on a vehicle, or moving the
vehicle with the tires installed, or checking
tire inflation. Do not place tires near heaters
or heating devices used to warm the room
where the tires are stored. Do not apply heat
or blow heated air directly on the tires.
Always inspect the tires after storage periods
and before use. USING SNOW CHAINS WARNING:
Do not exceed 30 mph
(50 km/h). Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use snow chains
on snow-free roads. WARNING:
Only fit snow chains to
specified tires. WARNING:
If your vehicle is fitted
with wheel trims, remove them before
fitting snow chains. WARNING:
Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel can
affect the safety and performance of your
vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure. Follow the recommended tire inflation pressures
found on the Safety Compliance
Certification label, or the Tire Label on the
B-Pillar or the edge of the driver door.
Failure to follow this instruction could result
in loss of vehicle control, vehicle rollover,
or personal injury or death.
Only use snow chains on rear wheels. Install
snow chains in pairs. Do not use
self-tensioning snow chains.
Only use snow chains on the following
specified tire sizes:
• 255/60R19
•Only install chains that are 10 mm or
less.
• 255/55R20
•Only install chains that are 10 mm or
less.
We recommend you use steel wheels of the
same size and specification if snow chains
are required because chains may chip
aluminum wheels.
Follow these guidelines when using snow
tires and traction devices:

When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 mi (800 km)
of the message appearing. Make sure you
reset the Intelligent Oil-Life Monitor after
each oil change. See Oil Change Indicator
Reset (page 388).
If your information display resets prematurely
or becomes inoperative, you should perform
the oil change interval at six months or
5,000 mi (8,000 km)
from your last oil
change. Never exceed one year or 10,000 mi
(16,000 km)
between oil change intervals,
Your vehicle is very sophisticated and built
with multiple, complex performance systems.
Every manufacturer develops these systems
using different specifications and
performance features. That is why it is
important to rely upon your dealership to
properly diagnose and repair your vehicle. We have recommended maintenance
intervals for various parts and component
systems based upon engineering testing.
We rely upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance schedules
that deviate from the scheduled maintenance
information.
We strongly recommend the use of only our
genuine manufactured or our authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and our Workshop
Manual list the recommended additives and
chemicals for your vehicle. We do not
recommend using chemicals or additives not
approved by us as part of your vehicle
’s
normal maintenance. Please consult your
warranty information. Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal
operating characteristic and, by itself, does
not necessarily indicate a concern or that the
fluid needs to be changed. However, a
qualified expert, such as the factory-trained
technicians at your dealership, should
inspect discolored fluids that also show signs
of overheating or foreign material
contamination immediately.
Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle
sub-systems during scheduled maintenance.
It is critical that systems are flushed only with
new fluid that is the same as that required
to fill and operate the system or using our
approved flushing chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
