2023 LINCOLN AVIATOR traction control

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 you do stall out, do not try to turn around
because you might roll over. It is better to
back down 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; 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.

Reverse Braking Assist (If Equipped)

PRINCIPLE OF OPERATION
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: Operating your vehicle
with the traction control disabled could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system turns on each time you switch
on the ignition.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.Note:When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information display
showing system status.
You can switch the system off by accessing
the traction control settings through the
touchscreen. See Settings (page 555).
Note:If your vehicle detects a loss of traction
due to excessive wheel spin or deceleration,
a display message appears on the
touchscreen prompting you to disable
traction control if needed.
Using the Information Display Controls
You can switch this feature off or on in the
information display. See General
Information (page 136).

Traction Control

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death.
WARNING: Remember that even
advanced technology cannot defy the laws
of physics. It’s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator’s
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
The system automatically turns on each time
you switch the ignition on.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the systems applies higher
brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s ability
to prevent skids or lateral slides by applying
brakes to one or more of the wheels
individually and, if necessary, reducing
engine power.
282
Stability Control

Roll Stability Control
The system enhances your vehicle’s ability
to prevent rollovers by detecting your
vehicle’s roll motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
Curve Control
The system enhances your vehicle’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
Control operates by reducing engine power
and, if necessary, applying brakes to one or
more of the wheels individually.
Traction Control
The system enhances your vehicle’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 281).

WHAT IS HILL DESCENT CONTROL
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.
Note:The system does not function below
3 mph (5 km/h).
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.The system can maintain vehicle speeds on
downhill slopes between 3–20 mph
(5–32 km/h). Above 20 mph (32 km/h), the
system remains on but the descent speed
cannot be set or maintained.
The system requires a cool down interval
after a period of sustained use. The amount
of time that the system can remain active
before cooling varies with conditions. The
system 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.
SWITCHING HILL DESCENT
CONTROL ON AND OFF
You can switch the hill descent control on
and off through the touchscreen.
SETTING THE HILL DESCENT
SPEED
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake.
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.
To increase the descent speed, press the
accelerator pedal until you reach the speed
you prefer.
To decrease the descent speed, press the
brake pedal until you reach the speed you
prefer.

Hill Descent Control (If Equipped)

The system uses the front and rear
outermost parking aid sensors to detect
objects that are near to the sides of your
vehicle. The system displays them on a
virtual map in the information display as your
vehicle moves past them.
The sensors are on the front and rear
bumpers.
Note:Keep the sensors free from snow, ice
and large accumulations of dirt.
Note:Do not cover up the sensors.
Note:Do not clean the sensors with sharp
objects.
Note:If your vehicle sustains damage
leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts.
The system may not function if:
• You switch the ignition on, off and back
on within a few seconds.
• Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system activates.
• The traction control system activates.Note:If you switch traction control off, the
side sensing system also turns off.
Note:Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.
To reinitialize the system, you may have to
drive your vehicle approximately 10 ft (3 m).
E190458
The sensor coverage area is up to 24 in
(60 cm) from the side of your vehicle.When the system detects an object within
the coverage area and the driving path of
your vehicle, an audible warning sounds. As
your vehicle moves closer to the object, the
rate of the tone increases.
Note:The system does not detect an object
that is moving toward the side of your
vehicle, for example another vehicle moving
at low speed, if it does not pass a front or
rear sensor.
