clean but the message remains in the display
The collision warning system is
temporarily disabled. Collision warning should automatically reactivate a
short time after the weather conditions improve
Heavy rain, spray, snow, or fog is inter-
fering with the radar signals
The collision warning system is
temporarily disabled. Collision warning should automatically reactivate a
short time after the weather conditions improve
Swirling water, or snow or ice on the
surface of the road may interfere with the radar signals
System Limitations
WARNING
The collision warning system’s
brake support can only help
reduce the speed at which a collision
occurs if the driver applies the
vehicle’s brakes. The brake pedal
must be pressed just like any typical
braking situation.
Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision
warning. These include: • Stationary vehicles or vehicles
moving below 6 mph (10 km/h).
• Pedestrians or objects in the roadway.
• Oncoming vehicles in the same lane.
• Severe weather conditions (see blocked sensor section).
• Debris build-up on the grille near the headlamps (see blocked
sensor section).
• Small distance to vehicle ahead.
• Steering wheel and pedal movements are large (very active
driving style).

Driving Aids

If the front end of the vehicle is hit or
damaged, the radar sensing zone may
be altered causing missed or false
collision warnings. See your
authorized dealer to have your
collision warning radar checked for
proper coverage and operation.
STEERING
Electric Power Steering
WARNINGS
The electric power steering
system has diagnostic checks
that continuously monitor the system
to ensure proper operation. When a
system error is detected a steering
message will appear in the
information display.
The electric power steering
system has diagnostic checks
that continuously monitor the system
to ensure proper operation of the
electronic system. When an electronic
error is detected, a message will be
displayed in the information display.
If this happens, stop the vehicle in a
safe place, and turn off the engine.
After at least 10 seconds, reset the
system by restarting the engine, and
watch the information display for a
steering message. If a steering
message returns, or returns while
driving, take the vehicle to your dealer
to have it checked.
WARNINGS
Obtain immediate service if a
system error is detected. You
may not notice any difference in the
feel of your steering, but a serious
condition may exist. Failure to do so
may result in loss of steering control.
Your vehicle is equipped with an
electric power-assisted steering
system. There is no fluid reservoir to
check or fill.
If your vehicle loses electrical power
while you are driving (or if the ignition
is turned off), you can steer the
vehicle manually, but it takes more
effort. Extreme continuous steering
may increase the effort it takes for you
to steer. This occurs to prevent
internal overheating and permanent
damage to your steering system. If this
should occur, you will neither lose the
ability to steer the vehicle manually
nor will it cause permanent damage.
Typical steering and driving
maneuvers will allow the system to
cool and steering assist will return to
normal.
Steering Tips
If the steering wanders or pulls, check
for:
• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment
221
Driving Aids

A high crown in the road or high
crosswinds may also make the
steering seem to wander or pull.
Adaptive Learning
The EPS system adaptive learning
helps correct for road irregularities
and improves overall handling and
steering feel. It communicates with
the vehicle's brake system to help
operate advanced stability control
and accident avoidance systems.
Additionally, whenever the battery is
disconnected or a new battery
installed, the vehicle must be driven
a short distance before the strategy
is relearned and all systems are
reactivated.
DRIVE CONTROL
LINCOLN DRIVE CONTROL
Lincoln Drive Control delivers the
Lincoln driving experience through a
suite of sophisticated electronic
vehicle systems. These systems
continuously monitor both your driving
inputs and the road conditions to
optimize ride comfort, steering,
handling, powertrain response and
sound. You can preset your
preferences for these systems within
the information display. Lincoln Drive
Control will respond to your
preferences based on what gear
position you select. This provides a
single location to control multiple
systems performance settings.
Lincoln Drive Control consists of the
following systems:• Continuously Controlled Damping
dynamically adjusts the shock
absorbers stiffness in real time to
match the road surface and driver
inputs. Vehicle motion (roll, pitch,
bounce), suspension position,
vehicle loading, vehicle speed, road
conditions, and steering are
continuously monitored to adjust
the suspension damping for
optimal vehicle control.
• Electronically Power-Assisted Steering adjusts steering effort and
feel based on vehicle speed and
your inputs
• Active Noise Control utilizes vehicle electronics to enhance the
acoustic experience
• Electronic Stability Control and Traction Control maintain vehicle
control in adverse conditions or
high performance driving
• Electronic Throttle Control which enhances the powertrain response
to your inputs
These systems have a range of modes
which you can choose from in order
to customize your ideal driving
experience:
222
Driving Aids

• Comfort – Provides a more relaxeddriving experience, maximizing
comfort. Steering effort is
decreased and suspension
movement is more fluid. Comfort
mode is ideal when enhanced
traveling comfort is desired.
• Normal – Delivers a balanced combination of comfortable,
controlled ride and confident
handling. This mode provides an
engaging drive experience and a
direct connection to the road
without sacrificing any of the
composure demanded from a
luxury vehicle.
• Sport – Provides a sportier driving experience. Suspension stiffens,
with an emphasis on handling and
control. The engine responds more
directly to your inputs and takes
on a more powerful tone. Sport
mode is intended to be used during
more spirited driving.
Using Lincoln Drive Control
You can configure which of the Drive
Control modes are active when the
vehicle is in D (Drive) or in S (Sport).
The configuration is retained until
modified from the main menu on the
information display.
To change the vehicle’s Drive Control
settings from the main menu on the
information display:
1. Choose Settings.
2. Choose Driver Assist.
3. Choose Vehicle. 4. Select the shift position you would
like to configure, either D or S.
5. Choose from Comfort, Normal, or Sport modes as your preferred
setting in D.
6. Choose from Normal or Sport modes as your preferred setting in
S.
Note: Lincoln Drive Control has
diagnostic checks that continuously
monitor the system to ensure proper
operation. Certain types of system
errors will gray out the mode selections
within the information display,
preventing you from changing states
when the gear position is changed.
Other types of errors will produce a
temporary message that states Drive
Control Malfunction. If either condition
persists for multiple key cycles, take
your vehicle to an authorized dealer to
have it checked.

Trailer Lamps
WARNING
Never connect any trailer lamp
wiring to the vehicle's tail lamp
wiring; this may damage the electrical
system resulting in fire. Contact your
authorized dealer as soon as possible
for assistance in proper trailer tow
wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most
towed vehicles. Make sure all running
lights, brake lights, turn signals and
hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing
up to get the feel of your
vehicle-trailer combination before
starting on a trip. When turning, make
wider turns so the trailer wheels clear
curbs and other obstacles.
When Towing a Trailer
• Do not drive faster than 70 mph (113 km/h) during the first 500
miles (800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug
nuts thoroughly after you have
traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather,
place the gearshift in position 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
automatically when you are towing
on long, steep grades.
• Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as
they may overheat and become
less effective.
• If your transmission is equipped with a Grade Assist or Tow/Haul
feature, use this feature when
towing. This provides engine
braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade:
• Turn the steering wheel to pointyour vehicle tires away from
traffic flow.
• Set your vehicle parking brake.
• Place the automatic transmission in position P.
• Place wheel chocks in front and back of the trailer wheels.
(Chocks not included with
vehicle.)
Launching or Retrieving a Boat
or Personal Watercraft (PWC)
Note: Disconnect the wiring to the
trailer before backing the trailer into
the water.

If the engine reaches a preset
over-temperature condition, the
engine will automatically switch to
alternating cylinder operation. Each
disabled cylinder acts as an air pump
and cools the engine.
When this occurs, the vehicle will still
operate. However:
• The engine power will be limited.
• The air conditioning system will bedisabled.
Continued operation will increase the
engine temperature and the engine
will completely shut down, causing
steering and braking effort to increase.
Once the engine temperature cools,
the engine can be re-started. Take
your vehicle to an authorized dealer
as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use during
emergencies only. Operate the
vehicle in fail-safe mode only as long
as necessary to bring the vehicle to
rest in a safe location and seek
immediate repairs. When in fail-safe
mode, the 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.
WARNINGS
Never remove the coolant
reservoir cap while the engine is
running or hot.
You have limited engine power when
in the fail-safe mode, so drive the
vehicle with caution. The vehicle will
not be able to maintain high-speed
operation and the engine will run
rough. Remember that the engine is
capable of completely shutting down
automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Re-start the engine and take your vehicle to an authorized dealer.
Note: Driving the vehicle without
repairing the engine problem increases
the chance of engine damage. Take
your vehicle to an authorized dealer as
soon as possible.
