Park Brake Application
Automatic parking brake application and
cancellation occurs if:
• You unbuckle the seatbelt and open the
door after you stop the vehicle.
• You hold the vehicle at a stop
continuously for more than three minutes.
Hilly Condition Usage
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. Switching Adaptive Cruise Control Off For vehicles without Speed Limiter,
press and release the button when
the system is in standby mode or
switch the ignition off. For vehicles with Speed Limiter,
press and release the button when
the system is in standby mode or
switch the ignition off.
Note: You erase the set speed when you
switch the system off.
Detection Issues WARNING: On rare occasions,
detection issues can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required.

CROSS TRAFFIC ALERT
(IF EQUIPPED) WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before
reversing out of a parking space. The cross
traffic alert system is not a replacement for
careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due care
and attention. Failure to take care may
result in a crash.
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
Using Cross Traffic Alert
The system detects vehicles that approach
at a speed between
4 mph (6 km/h) and
37 mph (60 km/h). Coverage decreases when
the sensors are partially, mostly or fully
obstructed. Slowly reversing helps increase
the coverage area and effectiveness.
The system turns on when you start the
engine and you shift into reverse (R). The
system turns off when you shift out of reverse
(R).

These systems have a range of modes which
you can choose from in order to customize
your ideal driving experience:
•
Comfort – Provides a more relaxed
driving experience, maximizing comfort.
Your steering effort decreases and the
suspension movement is more fluid.
Comfort mode is ideal when you desire
enhanced traveling comfort.
• 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. The 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 ideal for use during
more spirited driving.
You can change your vehicle's Drive Control
settings from the menu on the display
screen. See General Information (page 109). Note:
Not all settings may be available.
Note: Lincoln Drive Control has diagnostic
checks that continuously monitor the system
to ensure proper operation. Certain types of
system errors gray out the mode selections
within the information display, preventing
you from changing states when the gear
position is changed. Other types of errors
produce a temporary message in the
information display. See Information
Messages (page 115). If either condition
persists for multiple key cycles, see an
authorized dealer.

TOWING A TRAILER
WARNING: Do not exceed the
GVWR or the GAWR specified on the
certification label. WARNING:
Towing trailers
beyond the maximum recommended
gross trailer weight exceeds the limit
of your vehicle and could result in
engine damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and personal
injury.
Note: There may be electrical items
such as fuses or relays that can affect
trailer towing operation.
See Fuses
(page 281). The load capacity of your vehicle is
designated by weight not volume. You
may not necessarily be able to use all
available space when loading your
vehicle or trailer.
Towing a trailer places extra load on the
engine, transmission, axle, brakes, tires,
and suspension. Inspect these
components before, during and after
towing.
Load Placement
To help minimize how trailer movement
affects the vehicle when driving:
•
Load the heaviest items closest to
the trailer floor.
• Load the heaviest items in the center
of the left and right side trailer tires. •
Load the heaviest items above the
trailer axles or just slightly forward
toward the trailer tongue. Do not
allow the final trailer tongue weight
to go above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the correct
rise or drop. When both the loaded
vehicle and trailer are connected, the
trailer frame should be level, or
slightly angled down toward the
vehicle, when viewed from the side.
When driving with a trailer or payload, a
slight takeoff vibration or shudder may
be present due to the increased payload
weight. Additional information regarding
proper trailer loading and setting your
vehicle up for towing is located in the
Load Carrying chapter. See Load Limit
(page 251).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.

MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Towing

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 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled
50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (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:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P). 4. Place wheel chocks in front and back of
the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to rise
above the bottom edge of the rear
bumper.
• Do not allow waves to break higher than
6 in (15 cm)
above the bottom edge of
the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.

Replace the rear axle lubricant anytime you
submerge the rear axle in water. Water may
contaminate the rear axle lubricant, which is
not a normal maintenance inspection item
unless there is a possibility of a leak or other
axle repair is required.
TOWING THE VEHICLE ON FOUR
WHEELS
Emergency Towing
WARNING: If your vehicle has a
steering wheel lock make sure the ignition
is in the accessory or on position when
being towed. You can flat-tow (all wheels on the ground,
regardless of the powertrain/transmission
configuration) your disabled vehicle (without
access to wheel dollies, car-hauling trailer,
or flatbed transport vehicle) under the
following conditions:
•
Your vehicle is facing forward so you tow
it in a forward direction.
• You place the transmission in neutral (N).
If you cannot place the transmission in
neutral (N), you may need to override the
gear shifter.
See Automatic
Transmission (page 178).
• Maximum speed is
35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering the vehicle.
See
Climate Control (page 135). Follow these guidelines if you have a need
for recreational (RV) towing. An example of
recreational towing would be towing your
vehicle behind a motorhome. These
guidelines are to make sure you do not
damage the transmission during towing.
Vehicles Equipped with a 2.0L Engine
Front-wheel drive (FWD) vehicles
CANNOT
be flat-towed (all wheels on the ground) as
vehicle or transmission damage may occur.
You must place the front wheels on a
two-wheel tow dolly. If you are using a tow
dolly, follow the instructions specified by the
equipment provider.
All-wheel drive (AWD) vehicles CANNOT be
flat-towed (all wheels on the ground), as
vehicle or transmission damage may occur.
It is recommended to tow your vehicle with
all four (4) wheels off the ground such as
when using a car-hauling trailer. Otherwise,
you cannot tow your vehicle.
260
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Towing

Vehicles Equipped with a 3.0L Engine
You can tow your vehicle with all four wheels
on the ground using the Stay in Neutral
mode feature, or with all four wheels off the
ground using a vehicle transport trailer. If you

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
Avoid driving too fast during the first 1,000 mi
(1,600 km)
. Vary your speed frequently and
change up through the gears early. Do not
labor the engine.
Do not tow during the first
1,000 mi
(1,600 km).
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
102).
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 308).
5. Have your vehicle checked as soon as possible. ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
262
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Driving Hints

There are also some things you may want to
avoid doing because they reduce your fuel
economy:
•
Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly terrain.
• Do not rest your foot on the brake pedal
while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment. DRIVING THROUGH WATER WARNING: Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the front rocker
area of your vehicle. When driving through standing water, drive
very slowly and do not stop your vehicle.
