heating LINCOLN AVIATOR 2021 User Guide

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; instead, disengage
overdrive or manually shift 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 the vehicle.
Your vehicle has anti-lock brakes, therefore
apply the brakes steadily. Do not “pump
” the
brakes.
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. Note:
Excessive tire slippage can cause
driveline damage.
AWD vehicles have advantages over 2WD
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 as well. Although an
AWD vehicle could accelerate better than a
two-wheel drive vehicle in snow and ice, it
will not stop any faster, because as in other
vehicles, 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.
Since your vehicle is equipped with a four
wheel (ABS), do not “pump
” the brakes. See
Hints on Driving With Anti-Lock Brakes
(page
258).
Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and tested
to provide predictable performance whether
loaded or empty and durable load carrying
capability. For this reason, we strongly
recommend that you do not make
modifications such as adding or removing
parts (such as lowering kits or stabilizer bars)
or by using replacement parts not equivalent
to the original factory equipment.

Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle
’s regular brake system to prevent it
from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
ADAPTIVE CRUISE CONTROL
LIMITATIONS - VEHICLES WITH:
ADAPTIVE CRUISE CONTROL
WITH LANE CENTERING
Adaptive cruise control limitations apply to
lane centering unless stated otherwise or
contradicted by a lane centering limitation.
See Adaptive Cruise Control Limitations
(page 293). The system may not correctly operate in any
of the following conditions:
•
Your vehicle is not centered in the lane.
• The lane is too narrow or wide.
• The system does not detect at least one
lane marking or when lanes merge or
split.
• You switch the direction indicator on.
• Limited steering torque input is applied.
• Areas under construction or new
infrastructure.
• When modifications to the steering
system have been made.
• When using a spare tire.
Note: The driving assistance torque is limited
and may not be sufficient for all driving
situations such as driving through tight
curves or driving through curves at high
speeds.
Note: In exceptional conditions, the system
may deviate from the center line. ADAPTIVE CRUISE CONTROL

(If Equipped)

Extreme continuous steering could increase
the effort you need to steer your vehicle. This
increased effort prevents overheating and
permanent damage to the steering system.
You do not lose the ability to manually steer
your vehicle. Typical steering and driving
maneuvers allow the system to cool and
operate as normal.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds could also make the steering
seem to wander or pull. Adaptive Learning
The electronic power steering system
adaptive learning improves overall handling
and steering on roads with irregularities. It
communicates with the brake system to help
operate advanced stability control and
accident avoidance systems. When you
install a new battery or disconnect the
battery, you need to drive your vehicle a
short distance so it can relearn and reactivate
all systems.
PRE-COLLISION ASSIST
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. WARNING:
The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury. WARNING:
The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.

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 Gauges (page
126).
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 Engine
Coolant Check (page 390).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the conditions
you drive under, and how you maintain your
vehicle.
You may improve your fuel economy by
keeping these things in mind:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without stopping.
• Anticipate stops; slowing down may
eliminate the need to stop. •
Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling at
55 mph [88 km/h] uses 15% less fuel than
traveling at 65 mph [105 km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold mornings.
• Use the air conditioner or front defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.

Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Driving Hints

WARNING: Do not add coolant
further than the MAX mark.
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 564).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
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:
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 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 put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield. 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 450). 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 may not be
covered by the vehicle Warranty.
Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.
See
Capacities and Specifications (page 450).
Using water that has not been deionised
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.
391
Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Maintenance

Note:
Coolants marketed for all makes and
models may not be approved to our
specifications and may cause damage to
the cooling system. Resulting component
damage may not be covered by the vehicle
Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant approved to the correct specification. See Capacities and
Specifications (page 450).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap. Turn the cap clockwise until it contacts the
hard stop.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level. 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. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with engine coolant 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:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze. Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of the
coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Note:
Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
392
Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Maintenance

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.
