Answer
Question
In order to make sure 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 coolant temperature.
Why does my engine stay on when it is extremely cold outside?
Your vehicle's engine and transmission are designed to deliver thepower you need at the most efficient engine speed. This may be
higher than expected during heavy accelerations, and may fluctuate when driving at a steady speed. These are characteristics of the
Atkinson engine cycle and the transmission technology that help maximize your hybrid's fuel economy.
Why does my engine rev up so high sometimes when I accelerate?
Change the engine oil every 10,000 mi (16,000 km) or once per yearunder normal operating conditions.
What is the engine oil change service interval?
Yes. Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline)fuel, but you may notice slightly reduced fuel economy because
ethanol contains less energy per gallon than gasoline. Your hybrid vehicle is not designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how will it affect my fuel
economy?

Have an authorized dealer check and change
the transmission fluid at the correct service
interval. See Maintenance (page 301). Your
transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
(i.e., if the transmission slips or shifts slowly)
or if you notice some sign of fluid leakage.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.
BRAKE FLUID CHECK
WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death. WARNING: Only use brake fluid from
a sealed container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. WARNING:
Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician. WARNING:
The brake system could
be affected if the brake fluid level is below
the
MIN mark or above the MAX mark on
the brake fluid reservoir. 1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative to
the
MIN and the MAX marks on the
reservoir.
Note: If the brake fluid level is between the
MIN
and the MAX marks on the reservoir, it
is acceptable.

MKZ (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201905, Second-Printing MaintenanceE170684
Note:
If the brake fluid level is below the MIN
mark or above the MAX mark, have your
vehicle checked as soon as possible.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our specifications.
See
Capacities and Specifications (page
359).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.
For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide. WASHER FLUID CHECK WARNING:
If you operate your
vehicle in temperatures below 41.0°F (5°C),
use washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze
protection in cold weather could result in
impaired windshield vision and increase
the risk of injury or accident.
Note: The front and rear washer systems
are supplied from the same reservoir.
Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets our
specifications.
See Capacities and
Specifications (page 359).
State or local regulations on volatile organic
compounds may restrict the use of methanol,
a common windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents should be
used only if they provide cold weather
protection without damaging the vehicle ’s
paint finish, wiper blades or washer system. FUEL FILTER
Your vehicle is equipped with a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
CHANGING THE 12V BATTERY
WARNING:
Batteries normally
produce explosive gases which can cause
personal injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in personal
injury and damage to the vehicle or battery.
Lift the battery with a battery carrier or with
your hands on opposite corners.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when you
sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
We have established regular maintenance
intervals for your vehicle based upon
rigorous testing. It is important that you have
your vehicle serviced at the proper times.
These intervals serve two purposes; one is
to maintain the reliability of your vehicle and
the second is to keep your cost of owning
your vehicle down.
It is your responsibility to have all scheduled
maintenance performed and to make sure
that the materials used meet the
specifications identified in this owner's
manual. See Capacities and Specifications
(page 359).
Failure to perform scheduled maintenance
invalidates warranty coverage on parts
affected by the lack of maintenance.
Why Maintain Your Vehicle at Your
Dealership?
Factory-Trained Technicians
Service technicians participate in extensive
factory-sponsored certification training to
help them become experts on the operation
of your vehicle. Ask your dealership about
the training and certification their technicians
have received.
Genuine Ford and Motorcraft® Replacement
Parts
Dealerships stock Ford, Motorcraft and
Ford-authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed at
your dealership carry a nationwide 24-month
or unlimited mile (kilometer) parts and labor
limited warranty.
If you do not use Ford authorized parts they
may not meet our specifications and
depending on the part, it could affect
emissions compliance.
Convenience
Many dealerships have extended evening
and Saturday hours to make your service
visit more convenient and they offer one stop
shopping. They can perform any services
that are required on your vehicle, from
general maintenance to collision repairs.
Note:
Not all dealers have extended hours
or body shops. Please contact your dealer
for details.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved reliability,
durability and resale value. To maintain the
proper performance of your vehicle and its
