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?

Changing the Set Speed
•
Accelerate or brake to the desired speed,
then press and release SET+.
• Press and hold
SET+ or SET- until the
desired set speed shows on the
information display. The vehicle speed
will gradually change to the selected
speed.
• Press and release SET+ or SET-. The set
speed will change in approximately 1 mph
(2 km/h) increments.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed will display continuously in the
information display while the system is active.
Resuming the Set Speed
Note: Only use resume if you are aware of
the set speed and intend to return to it.
Press and release
RES. The vehicle will
return to the previously set speed. The set
speed will display continuously in the
information display while the system is active. Low Speed Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An audible
alarm will sound and the automatic braking
releases if the vehicle drops below this
speed.
Hilly Condition Usage
Note:
An audible alarm will sound and the
system will shut down if it is applying brakes
for an extended period of time. This allows
the brakes to cool down. The system will
function normally again when the brakes
have cooled down.
You should select a lower gear position
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
them from overheating.
Switching the System Off
Note: The set speed memory erases when
you switch off the system. Press and release OFF
or turn off the ignition.
Detection Issues
The radar sensor has a limited field of vision.
It may not detect vehicles at all or detect a
vehicle later than expected in some
situations. The lead vehicle graphic will not
illuminate if the system does not detect a
vehicle in front of you.

MKZ Hybrid (), enUSA Cruise Control

If your vehicle loses electrical power while
you are driving (or if you switch the ignition
off ), you can steer your 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 your vehicle
manually nor will it cause permanent
damage. Typical steering and driving
maneuvers allows the system to cool and
steering assist to 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.
A high crown in the road or high crosswinds
may also make the steering seem to wander
or pull. Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with the
brake system to help operate advanced
stability control and accident avoidance
systems. Additionally, whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short distance
before the system relearns the strategy and
reactivates all systems.
COLLISION WARNING SYSTEM
PRINCIPLE OF OPERATION (If Equipped)
WARNINGS
This system is designed to be a
supplementary driving aid. It is not
intended to replace the driver’ s attention,
and judgment, or the need to apply the
brakes. This system does NOT activate the
brakes automatically. Failure to press the
brake pedal to activate the brakes may result
in a collision. WARNINGS
The collision warning system with
brake support cannot help prevent all
collisions. Do not rely on this system to
replace driver judgment and the need to
maintain distance and speed. Note:
The system does not detect, warn or
respond to potential collisions with vehicles
to the rear or sides of the vehicle.
Note: The collision warning system is active
at speeds above approximately 5 mph (8
km/h). This system is designed to alert the driver of
certain collision risks. A radar detects if your
vehicle is rapidly approaching another
vehicle traveling in the same direction as
yours.

Checking the Inverter System
Controller Coolant
When the engine is cold, check the
concentration and level of the inverter
system controller coolant at the intervals
listed in the scheduled maintenance
information. See Scheduled Maintenance
(page 468).
Note: Make sure that the level is between
the MIN and MAX marks on the inverter
system controller coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add prediluted
coolant immediately. See
Adding Inverter
System Controller Coolant in this chapter.
The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30°F
(-34°C) and -34°F (-37°C). Note:
For best results, coolant concentration
should be tested with a refractometer such
as Robinair Coolant and Battery
Refractometer 75240. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Adding Coolant WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling system
can burn you badly. Also, you can be burned
if you spill coolant on hot engine parts. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine coolant
could make it difficult to see through the
windshield. WARNINGS
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam
and hot liquid can come out forcefully when
the cap is loosened slightly. Do not add coolant further than the
MAX mark.
Note:
Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the cooling or heating
systems. This damage would not be covered
under your vehicle ’s warranty.
Note: During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.

Note:
It is very important to use prediluted
coolant meeting the Ford specification in
order to avoid plugging the small coolant
passageways. Use of concentrated coolant
and water may cause coolant passageway
plugging and void the warranty. See
Capacities and Specifications (page 346). •
Do not mix different colors or types of
coolant in your vehicle. Make sure the
correct coolant is used. Mixing of
coolants may harm your cooling system.
The use of an improper coolant may harm
the engine, inverter system controller,
and cooling system components and may
void the warranty.
• In case of emergency, a large amount of
water without engine coolant may be
added to the engine cooling system in
order to reach a vehicle service location.
In this instance, the engine cooling
system must be drained, chemically
cleaned with Motorcraft Premium Cooling
System Flush, and refilled with prediluted
engine coolant as soon as possible.
Water alone (without engine coolant) can
cause engine damage from corrosion,
overheating, or freezing. DO NOT use
this method for the inverter system
controller cooling system. The inverter
system controller cooling system
operates close to ambient temperature,
and is susceptible to freezing in any
subfreezing environment in the absence
of coolant. •
Do not use alcohol, methanol, brine or
any engine coolants mixed with alcohol
or methanol antifreeze (coolant). Alcohol
and other liquids can cause engine
damage from overheating or freezing.
• Do not add extra inhibitors or additives
to the coolant. These can be harmful and
compromise the corrosion protection of
the engine coolant.
Adding Engine Coolant
1. Unscrew the engine coolant reservoir cap slowly. Any pressure will escape as
you unscrew the cap.
2. Use a funnel to add prediluted engine coolant to the engine coolant reservoir.
Make sure that the level is between the
MIN and MAX marks on the engine
coolant reservoir. Use prediluted engine
coolant meeting the Ford specification.
See Capacities and Specifications (page
346
).
3. Close the engine coolant reservoir cap.

Your vehicle is equipped with an information
display, which indicates the proper oil
change interval. This interval may be up to
one year or 10000 miles (16000 kilometers).
When ENGINE OIL CHANGE DUE or OIL
CHANGE REQUIRED appears in the
information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 miles (800
kilometers) of the
ENGINE OIL CHANGE
DUE or OIL CHANGE REQUIRED message
appearing. Make sure you reset the oil
monitoring system after each oil change.
See
Engine Oil Check (page 288).
If your information display resets
prematurely, becomes inoperative or the
vehicle battery becomes discharged or
disconnected, the oil monitoring system
resets to 100% oil life. You should change
your engine oil one year or 10000 miles
(16000 kilometers) from the previous oil
change. Never exceed one year or 10000
miles (16000 kilometers) between oil change
intervals. Your vehicle is very sophisticated and built
with multiple, complex, performance systems.
Every manufacturer develops these systems
using different specifications and
performance features. That is why it is
important to rely upon your dealership to
properly diagnose and repair your vehicle.
Ford Motor Company has recommended
maintenance intervals for various parts and
component systems based upon engineering
testing. Ford Motor Company relies upon this
testing to determine the most appropriate
mileage for replacement of oils and fluids to
protect your vehicle at the lowest overall cost
to you and recommends against
maintenance schedules that deviate from
the scheduled maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or Ford-authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and the Ford Workshop
Manual list the recommended additives and
chemicals for your vehicle. We do not
recommend using chemicals or additives not
approved by us as part of your vehicle
’s
normal maintenance. Please consult your
warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal
operating characteristic and, by itself, does
not necessarily indicate a concern or that the
fluid needs to be changed. However, a
qualified expert, such as the factory-trained
technicians at your dealership, should
inspect discolored fluids that also show signs
of overheating or foreign material
contamination immediately.
