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.

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?

MKZ Hybrid (), enUSA Unique Driving Characteristics

Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International Lubricants
Specification Advisory Council (ILSAC),
comprised of U.S. and Japanese automobile
manufacturers.
1. Remove the filler cap.
2. Add engine oil that meets the Ford
specifications. See Capacities and
Specifications (page 346).
3. Replace the filler cap. Turn it until you feel a strong resistance. ENGINE COOLANT CHECK
Engine Coolant and Inverter System
Controller Coolant
Your vehicle is equipped with two separate
cooling systems. One is for cooling the
engine and one is for cooling the inverter
system controller that is specific to the hybrid
operating system. The two systems operate
similarly, with the inverter system controller
cooling system generally operating at a lower
temperature and pressure.
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine 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 engine
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 Engine
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.
289
MKZ Hybrid (), enUSA Maintenance

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.
