ignition LINCOLN MKZ HYBRID 2017 Service Manual

During certain events (such as vehicle
servicing) your low voltage 12-volt battery
may become disconnected or disabled. Once
the battery is reconnected and after driving
the vehicle, the engine may continue to
operate for three to five seconds after the
key is turned to off. This is a normal
condition.
Braking:
Your hybrid is equipped with standard
hydraulic braking and regenerative braking.
Regenerative braking is performed by your
transmission and it captures brake energy
and stores it in your high voltage battery.
Driving to Optimize Fuel Economy
Note:
Having your engine running is not
always an indication of inefficiency. In some
cases, it is actually more efficient than
driving in electric mode. Your fuel economy should improve
throughout your hybrid's break-in period. As
with any vehicle, your driving habits and
accessory usage can significantly impact
your fuel economy. For best results, keep in
mind these tips:
•
Keep the tires properly inflated and only
use the recommended size.
• Aggressive driving increases the amount
of energy required to move your vehicle.
In general, you can achieve better fuel
economy with mild to moderate
acceleration and deceleration. Moderate
braking is particularly important since it
allows you to maximize the energy
captured by the regenerative braking
system.
Additional Tips:
• Do not carry extra loads.
• Be mindful of adding external
accessories that may increase
aerodynamic drag.
• Observe posted speed limits. •
Perform all scheduled maintenance.
• There is no need to wait for your engine
to warm up. The vehicle is ready to drive
immediately after starting.
EV+ Mode
Your vehicle will recognize your frequent
destinations and allow for more EV driving
as you approach them. For example, when
nearing your home it should be easier to stay
in electric mode. The EV indicator will display
EV+ when this mode is active. You should
see this approximately 1/8 mile (200 meters)
from a frequent destination. See Information
Displays (page 108).
Note: Frequent destinations are learned by
your vehicle after two to four weeks of use.
To add a destination immediately, perform
the following process: cycle the ignition on
for 2 seconds, but do not start your vehicle,
then off for 2 seconds. Repeat the process
10 times. This location is now programmed
for EV+. You can clear these destinations
with a Driving History reset through the
Settings menu.

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS
Answer
Question
The high voltage battery is electrically isolated from the rest of the
vehicle when the key is off. When you switch the key on, high voltage
contactors inside the battery are closed to make the electricity avail-
able to the motor and generator and enable the vehicle to drive. The
clicks are the sound of these contactors as they close and open during start up and shut down.
What are the series of clicks from the cargo area when I first turn the
key in the ignition?
The vehicle's computer will determine if an engine start is requiredat key-on. Silent key start will start the engine if it is necessary for
cabin heating, windshield defrost, or if the outside temperature is low.
(For C-MAX Energi vehicles, the engine may not be required to operate these functions.)
Why does the engine sometimes start at key-on?
There are several reasons the engine stays on for an extended amountof time when you first start it. One common reason is to make sure
that the emissions components are warm enough to minimize tailpipe
emissions. As the climate gets cooler, this engine-on time is extended.
Why does it take a long time before the engine shuts down?
The engine is required to turn on above this speed to protect thetransmission hardware.
Why does my engine never shut down above 85 mph (137 km/h)

Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact an
authorized dealer to prevent any engine
damage.
Fuel Freshness Mode (If Equipped)
This helps keep the fuel system functional
and the fuel fresh.
If you mainly use your vehicle in electric
power mode without refueling, the gasoline
in the fuel tank may become stale due to
aging. Stale gasoline can damage the
engine and fuel system.
Your vehicle automatically switches to fuel
freshness mode if you do not refuel your
vehicle with fresh fuel within an 18-month
period. Fuel freshness mode protects your
vehicle from potential engine and fuel system
damage caused by using stale fuel.
Note: If you do not add new fuel during an
18-month period, fuel freshness mode will
use fuel until approximately 1.2 gal (4.5 L) of
fuel remains in the fuel tank. During fuel freshness mode:
•
The information display will indicate fuel
freshness mode is active.
• The vehicle will only run in hybrid mode.
EV Now mode will not be available.
• Most of the plug-in power will be stored
until fuel freshness mode is completed.
Note: EV Now mode resumes when less than
1.2 gal (4.5 L) of fuel remains in the fuel tank.
Note: When the fuel level is less than
one-quarter full, refueling your vehicle will
end fuel freshness mode.
Note: We recommend you use a fuel
stabilizer if you use less than a full tank of
fuel during an 18-month period.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
vehicle components.
If you have run out of fuel: •
To start the vehicle with a keyless
ignition, just start the engine. Crank time
will be longer than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the vehicle. If the
vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters) may
be required.
• The service engine soon indicator may
come on.
Refilling With a Portable Fuel Container WARNINGS
Do not insert the nozzle of portable
fuel containers or aftermarket funnels
into the capless fuel system. This could
damage the fuel system and its seal, and
may cause fuel to run onto the ground
instead of filling the tank, which could result
in serious personal injury. Do not try to pry open or push open
the capless fuel system with foreign
objects. This could damage the fuel system
and its seal and cause injury to you or others. 177

FUEL CONSUMPTION
Note:
The amount of usable fuel in the empty
reserve varies and should not be relied upon
to increase driving range. When refueling
your vehicle after the fuel gauge indicates
empty, you might not be able to refuel the
full amount of the advertised capacity of the
fuel tank due to the empty reserve still
present in the tank.
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. Do not rely on this fuel for
driving. The usable capacity of the fuel tank
is the amount of fuel that can be put into the
tank after the gauge indicates empty. The
advertised capacity is the total fuel tank size
– it is the combined usable capacity plus the
empty reserve.
Filling the Tank
For consistent results when filling the fuel
tank: •
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate (low-medium-high)
each time the tank is filled.
• Allow no more than two automatic
click-offs when filling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1000 miles (1600 kilometers) of driving
(this is your engine ’s break-in period); a more
accurate measurement is obtained after
2000 miles - 3000 miles (3200 kilometers -
4800 kilometers). Also, fuel expense,
frequency of fill ups or fuel gauge readings
are not accurate ways to measure fuel
economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added. 3.
After at least three to five tank fill ups, fill
the fuel tank and record the current
odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles
traveled by gallons used (For Metric:
Multiply liters used by 100, then divide
by kilometers traveled).
Keep a record for at least one month and
record the type of driving (city or highway).
This provides an accurate estimate of the
vehicle ’s fuel economy under current driving
conditions. Additionally, keeping records
during summer and winter show how
temperature impacts fuel economy. In
general, lower temperatures mean lower fuel
economy.

EMISSION CONTROL SYSTEM
WARNINGS
Do not park, idle, or drive your vehicle
in dry grass or other dry ground cover.
The emission system heats up the engine
compartment and exhaust system, which can
start a fire. Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If you smell
exhaust fumes inside your vehicle, have your
dealer inspect your vehicle immediately. Do
not drive if you smell exhaust fumes. Your vehicle is equipped with various
emission control components and a catalytic
converter that will enable your vehicle to
comply with applicable exhaust emission
standards. To make sure that the catalytic
converter and other emission control
components continue to work properly:
•
Use only the specified fuel listed.
• Avoid running out of fuel. •
Do not turn off the ignition while your
vehicle is moving, especially at high
speeds.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
The scheduled maintenance items listed in
scheduled maintenance information are
essential to the life and performance of your
vehicle and to its emissions system. See
Scheduled Maintenance (page 479).
If you use parts other than Ford, Motorcraft
or Ford-authorized parts for maintenance
replacements, or for service of components
affecting emission control, such non-Ford
parts should be the equivalent to genuine
Ford Motor Company parts in performance
and durability.
Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly. An improperly operating or damaged exhaust
system may allow exhaust to enter the
vehicle. Have a damaged or improperly
operating exhaust system inspected and
repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles are
not permitted to intentionally remove an
emission control device or prevent it from
working. Information about your vehicle
’s
emission system is on the Vehicle Emission
Control Information Decal located on or near
the engine. This decal also lists engine
displacement

ignition key to the on position for 15 seconds
without cranking the engine. If the service
engine soon indicator blinks eight times, it
means that the vehicle is not ready for I/M
testing; if the service engine soon indicator
stays on solid, it means that the vehicle is
ready for I/M testing.
The OBD-II system monitors the emission
control system during normal driving. A
complete check may take several days. If the
vehicle is not ready for I/M testing, you may
need to perform the following driving cycle
consisting of mixed city and highway driving:
Drive on an expressway or highway for a
steady 15 minutes, followed by 20 minutes
of stop-and-go driving with at least four
30-second idle periods.
Allow the vehicle to sit for at least eight hours
without starting the engine. Then, start the
engine and complete the above driving
cycle. The engine must warm up to its normal
operating temperature. Once started, do not
turn off the engine until the above driving
cycle is complete. If the vehicle is still not
ready for I/M testing, you will have to repeat
the above driving cycle.

Reactivating the High Voltage Battery
Note: If you have manually disconnected
your high voltage shut off circuit, you need
to reconnect the circuit before you can
reactivate it. The vehicle will detect if the
electrical system is safe and reactivate
automatically.
HIGH VOLTAGE BATTERY CUT-
