ignition LINCOLN MKZ HYBRID 2015 Service Manual

GENERAL INFORMATION
WARNINGS
Extended idling at high engine speeds
can produce very high temperatures
in the engine and exhaust system, creating
the risk of fire or other damage. Do not park, idle or drive your vehicle
on dry grass or other dry ground cover.
The emission system heats up the engine
compartment and exhaust system, creating
the risk of fire. Do not start the vehicle in a closed
garage or in other enclosed areas.
Exhaust fumes can be toxic. Always open
the garage door before you start the vehicle. If you smell exhaust fumes inside your
vehicle, have your vehicle checked by
an authorized dealer immediately. Do not
drive your vehicle if you smell exhaust fumes. If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5 miles (8
kilometers) after you reconnect it. This is
because the engine management system
must realign itself with the engine. You can
disregard any unusual driving characteristics
during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the vehicle, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the vehicle.
KEYLESS STARTING
Note:
The keyless starting system may not
function if the key is close to metal objects
or electronic devices such as cellular
phones.
Note: A valid key must be located inside
your vehicle to switch the ignition on and
start the vehicle. Ignition Modes
163
MKZ Hybrid (), enUSA Starting and Stopping the EngineE164319

The keyless starting system has three
modes:
•
Off: Turns the ignition off.
• Without applying the brake pedal,
press and release the button once
when the ignition is in the on mode,
or when the vehicle is running but is
not moving.
• On:
All electrical circuits are operational
and the warning lamps and indicators
illuminate.
• Without applying the brake pedal,
press and release the button once.
• Start:
Starts the vehicle. The engine may
not start when the vehicle starts.
• Press the brake pedal, and then press
the button until the vehicle starts. An
indicator light on the button
illuminates when then ignition is on
and when the vehicle starts. STARTING A GASOLINE ENGINE
When the engine starts for the first time on
your drive, the idle speed increases, this
helps to warm up the engine. If the engine
idle speed does not slow down automatically,
have your vehicle checked by an authorized
dealer.
Note:
You can crank the engine for a total
of 60 seconds (without the engine starting)
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each time,
without the engine starting, you reached the
60-second time limit. A message appears in
the information display alerting you that you
exceeded the cranking time. You cannot
attempt to start the engine for at least 15
minutes. After 15 minutes, you are limited to
a 15-second engine cranking time. You need
to wait 60 minutes before you can crank the
engine for 60 seconds again. Before starting the vehicle, check the
following:
•
Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and electrical
accessories are off.
• Make sure the parking brake is on.
• Put the transmission in
P .
Note: Do not touch the accelerator pedal.
1. Fully press the brake pedal.
2. Press the button.
Note: The green ready indicator illuminates
letting you know that the vehicle is ready for
driving. Since your vehicle is equipped with
a silent key start, the engine may not start
at the time of the vehicle start.
See Hybrid
Electric Vehicle (page 168).
The system does not function if:
• The key frequencies are jammed.
• The key battery has no charge.
If you are unable to start the vehicle, do the
following:
164
MKZ Hybrid (), enUSA Starting and Stopping the Engine

1. Remove the rubber covering (A) in the
cupholder. Place the remote in the
backup slot (B) at the bottom of the
cupholder.
2. With the key in this position, press the brake pedal, then the START button to
switch the ignition on and start your
vehicle.
Fast Restart
The fast restart feature allows you to restart
the vehicle within 20 seconds of switching
it off, even if a valid key is not present. Within 20 seconds of switching the vehicle
off, press the brake pedal and press the
button. After 20 seconds have expired, you
can no longer restart the vehicle without the
key present inside your vehicle.
Once the vehicle has started, it remains
running until you press the button, even if
the system does not detect a valid key. If you
open and close a door while the vehicle is
running, the system searches for a valid key.
You cannot restart the vehicle if the system
does not detect a valid key within 20
seconds.
Automatic Shutdown
This feature automatically shuts down the
vehicle if it has been idling for an extended
period. The ignition also turns off in order to
save battery power. Before the vehicle shuts
down, a message appears in the information
display showing a timer counting down from
30 seconds. If you do not intervene within
30 seconds, the vehicle shuts down. Another
message appears in the information display
to inform you that the vehicle has shut down
in order to save fuel. Start your vehicle as
you normally do.Automatic Shutdown Override
Note:
You cannot permanently switch off the
automatic shutdown feature. When you
switch it off temporarily, it turns on at the
next ignition cycle.
You can stop the shutdown, or reset the
timer, at any point before the 30-second
countdown has expired by doing any of the
following:
• You can reset the timer by interacting
with your vehicle (such as pressing the
brake pedal or accelerator pedal).
• You can temporarily switch off the
shutdown feature any time the ignition is
on (for the current ignition cycle only).
Use the information display to do so. See
Information Displays (page 109).
• During the countdown before shutdown,
you are prompted to press OK or RESET
(depending on your type of information
display) to temporarily switch the feature
off (for the current ignition cycle only).

Switching Off the Vehicle When It Is
Stationary
1. Put the transmission in position P.
2. Press the button once.
3. Apply the parking brake.
Note: This switches off the ignition, all
electrical circuits, warning lamps and
indicators.
Note: If the engine is idling for 30 minutes,
the ignition and engine automatically shut
down.
Switching Off the Vehicle When It Is
Moving WARNING
Switching off the engine when the
vehicle is still moving will result in a
loss of brake and steering assistance. The
steering will not lock, but higher effort will
be required. When the ignition is switched
off, some electrical circuits, warning lamps
and indicators may also be off. 1. Put the transmission in position
N and
use the brakes to bring your vehicle to a
safe stop.
2. When your vehicle has stopped, put the transmission in position
P.
3. Press and hold the button for one second, or press it three times within two
seconds.
4. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING
If you smell exhaust fumes inside your
vehicle, have your vehicle checked by
your authorized dealer immediately. Do not
drive your vehicle if you smell exhaust fumes.
Carbon monoxide is present in exhaust
fumes. Take precautions to avoid its
dangerous effects. Important Ventilating Information
If you stop your vehicle and the leave the
engine idling for long periods of time, we
recommend that you do one of the following:•
Open the windows at least 1 inch (2.5
centimeters)
• Set your climate control to outside air.
ENGINE BLOCK HEATER (If Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury. Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. Note:
The heater is most effective when
outdoor temperatures are below 0°F (-18°C).
The heater acts as a starting aid by warming
the engine coolant. This allows the climate
control system to respond quickly. The
equipment includes a heater element
(installed in the engine block) and a wire
harness. You can connect the system to a
grounded 120-volt AC electrical source.

HYBRID ELECTRIC VEHICLE
This hybrid vehicle combines electric and
gasoline propulsion to provide performance
and efficiency. It requires no special fuels
and you never have to plug it in.
Note:
You may notice higher engine speeds
upon start-up. This temporary condition is
normal and necessary to heat up the cabin
and minimize emissions. Starting: Switch the ignition on
while your transmission is in park
(P). The green ready indicator light
will appear in the instrument cluster, letting
you know that the vehicle is ready for driving.
The engine may not start because this
vehicle is equipped with silent key start. This
fuel saving feature allows your vehicle to be
ready to drive without requiring the gas
engine to be running. This indicator will
remain on while the vehicle is on, whether the engine is running or not to indicate the
vehicle is capable of movement (using its
electric motor, engine, or both). Typically, the
engine will not start unless the vehicle is
cold, you make a climate control change, or
you press the accelerator.
Driving:
The gas engine automatically starts
and stops to provide power when needed
and to save fuel when not needed. While
coasting at low speeds, coming to a stop, or
standing, the gas engine normally shuts
down and the vehicle operates in
electric-only mode. Conditions that may
cause the engine to start up or remain
running include:
• Considerable vehicle acceleration.
• Vehicle speed above 85 mph (137 km/h)
However, the maximum speed for
electric–only operation may be lower
while driving in hot temperatures or on
hilly terrain.
• Ascending a hill.
• Charge level of high voltage battery is
low. •
Very high or low outside temperature (to
provide system cooling or heating).
• Engine not warm enough to provide
passenger requested cabin temperature.
Stopping:
The gas engine may shut off to
conserve fuel as you come to a stop.
Restarting the vehicle is not required. Simply
step on the accelerator when you are ready
to drive.
Transmission Operation:
Due to the
technologically advanced,
electronically-controlled continuously
variable transaxle, you will not feel shift
changes like those of a non-hybrid vehicle.
Note: Since engine speed is controlled by
the transmission, it may seem elevated at
times. This is normal hybrid operation and
helps deliver fuel efficiency and
performance.
Neutral:
It is not recommended to idle the
vehicle in neutral (N) for an extended period
of time because this will discharge your high
voltage battery and decrease fuel economy.
The engine will not start, and cannot provide
power to the hybrid system in neutral (N).

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 turn the key to on, high voltage
contactors inside the battery are closed to make the electricity avail-
able to the motor/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.
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 ensure 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)?
In order to ensure that the climate control system can begin heatingthe cabin or defrosting the windshield as soon as a driver requests it, the engine coolant temperature has to be kept sufficiently hot.
Keeping the engine on is required to maintain the correct minimum temperature.
Why does my engine stay on when it is extremely cold outside?

•
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. Note:
Do not use aftermarket funnels; they
will not work with the capless fuel system
and can damage it. The included funnel has
been specially designed to work safely with
your vehicle.
When filling the vehicle ’s fuel tank from a
portable fuel container, use the funnel
included with the vehicle.
176
MKZ Hybrid (), enUSA Fuel and Refueling

3.
Fill the vehicle with fuel from the portable
fuel container.
4. When done, clean the funnel or properly
dispose of it. Extra funnels can be
purchased from your authorized dealer
if you choose to dispose of the funnel.
REFUELING WARNINGS
Fuel vapor burns violently and a fuel
fire can cause severe injuries.
Read and follow all the instructions on
the pump island. WARNINGS
Switch off your engine when you are
refueling.
Do not smoke if you are near fuel or
refueling your vehicle.
Keep sparks, flames and smoking
materials away from fuel.
Stay outside your vehicle and do not
leave the fuel pump unattended when
refueling your vehicle. This is against the law
in some places. Keep children away from the fuel
pump; never let children pump fuel.
Do not use personal electronic devices
while refueling.
Use the following guidelines to avoid
electrostatic charge build-up when filling an
ungrounded fuel container:
•
Place approved fuel container on the
ground.
• Do not fill a fuel container while it is in
your vehicle (including the cargo area). •
Keep the fuel pump nozzle in contact
with the fuel container while filling.
• Do not use a device that would hold the
fuel pump handle in the fill position.
Easy Fuel™ Capless Fuel System WARNING
The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler door, do not refuel until
the sound stops. Otherwise, fuel may spray
out, which could cause serious personal
injury. When fueling your vehicle:
1. Put the vehicle in position P and switch
the ignition off.
178
MKZ Hybrid (), enUSA Fuel and RefuelingE157280

2. Press the center-rear edge of the fuel
filler door and release to open. Note:
Hold the handle of the fuel filler nozzle
higher while you insert the nozzle for easier
access. 3.
Slowly insert the fuel filler nozzle fully into
the fuel system to open both doors.
Leave the nozzle fully inserted until you
have stopped pumping fuel. Note:
Allow about five to ten seconds after
pumping fuel before removing the fuel filler
nozzle. This allows residual fuel to drain
back into the fuel tank and not spill onto the
vehicle.
4. After you have stopped pumping fuel, slowly remove the fuel filler nozzle. Note:
A fuel spillage concern may occur if
overfilling the fuel tank. Do not overfill the
tank to the point that the fuel is able to
bypass the fuel filler nozzle. The overfilled
fuel may run down the drain located below
and in front of the fuel filler door.
5. To close the fuel filler door, press the center-rear edge of the fuel filler door
and then release. The fuel door will latch
closed.
If the fuel fill inlet did not close properly, a
Check Fuel Fill Inlet message may appear
on the instrument cluster.
At the next opportunity, do the following:
1. Safely pull off the road.
2. Put the vehicle in position
P and switch
the ignition off.
3. Open the fuel filler door and remove any
visible debris from the fuel fill opening.
4. Insert the fuel fill nozzle, or the fuel fill funnel provided with the vehicle, several
times to allow the inlet to close properly.
This will dislodge any debris preventing
the inlet from sealing.

MKZ Hybrid (), enUSA Fuel and RefuelingE166527 E156032 E154765

If this action corrects the problem, the
message may not reset immediately. It may
take several driving cycles for the message
to turn off. A driving cycle consists of an
engine start-up (after four or more hours with
the engine off ) followed by city or highway
driving. Continuing to drive with the message
on may cause the service engine soon lamp
to turn on as well.
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).
