engine is running.
Do not use supplemental engine oil additives
because they are unnecessary and could
lead to engine damage that may not be
covered by the vehicle Warranty. 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 Committee (ILSAC),
comprised of U.S. and Japanese automobile
manufacturers.
To top up the engine oil level do the
following:
Clean the area surrounding the engine oil
filler cap before you remove it.
1. Remove the engine oil filler cap.
See
Under Hood Overview (page 297). Turn
it counterclockwise and remove it.

ENGINE COOLANT CHECK 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, spilling coolant on
hot engine parts can burn you. 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
you loosen the cap slightly. Do not add coolant further than the
MAX mark.
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 495).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
303
MKZ (CC9) Canada/United States of America, enUSA, First Printing Maintenance

Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We recommend,
Robinair® Coolant and Battery Refractometer
75240 (Rotunda tool part number:
ROB75240). We do not recommend the use
of hydrometers or coolant test strips for
measuring coolant concentration.
Note:
Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Adding Coolant WARNING
Never remove the coolant reservoir
cap while the engine is running or hot. It is very important to use prediluted coolant
meeting the correct specification in order to
avoid plugging the small passageways in the
engine cooling system. See Capacities and
Specifications (page 374). Incorrect
prediluted coolant use can cause damage
not covered by the vehicle Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant meeting the correct specification. See Capacities and
Specifications
(page 367).
3. Add enough prediluted coolant to reach
the correct level.
4. Replace the coolant reservoir cap, turn it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle. 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.
Do not mix different colors or types of
prediluted coolant in your vehicle. Mixing of
prediluted coolant or using an incorrect
prediluted coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.
In case of emergency, you can add a large
amount of water without prediluted coolant
in order to reach a vehicle service location.
On arrival do the following:
1. Drain the cooling system.
2. Chemically clean the cooling system. We
recommend Motorcraft Premium Cooling
System Flush.
3. Refill with prediluted coolant as soon as possible.

When this occurs, your vehicle still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNINGS
Fail-safe mode is for use during
emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in a
safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will have
limited power, will not be able to maintain WARNINGS
high-speed operation, and may completely
shut down without warning, potentially losing
engine power, power steering assist, and
power brake assist, which may increase the
possibility of a crash resulting in serious
injury. Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine may
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider. 3.
If this is not possible, wait a short period
for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management (If Equipped) WARNING
To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not be able
to accelerate with full power until the coolant
temperature reduces. 306
MKZ (CC9) Canada/United States of America, enUSA, First Printing Maintenance

If you tow a trailer with your vehicle, the
engine may temporarily reach higher a
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
You may notice a reduction in vehicle speed
caused by reduced engine power. In order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to pull off the road. You can
continue to drive your vehicle.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature does
not drop, follow the remaining steps.
3. Switch the engine off and wait for it to cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue. AUTOMATIC TRANSMISSION
