CABIN AIR FILTER
Your vehicle is equipped with a cabin air
filter, which gives you and your passengers
the following benefits:
• It improves your driving comfort by
reducing particle and odor concentration.
• It improves the interior compartment
cleanliness.
• It protects the climate control
components from particle deposits.
You can locate the cabin air filter behind the
glove box.
Note: Make sure you have a cabin air filter
installed at all times. This prevents foreign
objects from entering the system. Running
the system without a filter in place could
result in degradation or damage to the
system. Replace the filter at regular intervals. See
Scheduled Maintenance (page 475).
For additional cabin air filter information, or
to replace the filter, see a qualified
technician.

Within 20 seconds of switching the engine
off, press the brake pedal and press the
button. After 20 seconds have expired, you
can no longer restart the engine without the
key present inside your vehicle.
Once the engine 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 engine is
running, the system searches for a valid key.
You cannot restart the engine if the system
does not detect a valid key within 20
seconds.
Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. Fully press the brake pedal.
2. Fully press the accelerator pedal and
hold it there.
3. Start the engine. 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.
Note: 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.
Automatic Engine Shutdown
If your vehicle is equipped with a keyless
ignition, it has a feature that automatically
shuts down the engine if it has been idling
for an extended period. The ignition also
turns off in order to save battery power.
Before the engine 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
engine shuts down. Another message
appears in the information display to inform
you that the engine has shut down in order
to save fuel. Start your vehicle as you
normally do.
Automatic Engine Shutdown Override
Note:
You cannot permanently switch off the
automatic engine shutdown feature. When
you switch it off temporarily, it turns on at
the next ignition cycle.

SAFETY PRECAUTIONS
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
The fuel system may be
under pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel until
the sound stops. Otherwise, fuel may spray
out, which could cause serious personal
injury. WARNING:
Fuels can cause serious
injury or death if misused or mishandled. WARNING:
Fuel may contain
benzene, which is a cancer-causing agent. WARNING:
When refueling always
shut the engine off and never allow sparks
or open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes.
Follow these guidelines when refueling:
• Extinguish all smoking materials and any
open flames before refueling your
vehicle.
• Always switch the engine off before
refueling.
• Automotive fuels can be harmful or fatal
if swallowed. Fuel is highly toxic and if
swallowed can cause death or permanent
injury. If fuel is swallowed immediately
call a physician, even if no symptoms are
immediately apparent. The toxic effects
of fuel may not be apparent for hours. •
Avoid inhaling fuel vapors. Inhaling fuel
vapor can lead to eye and respiratory
tract irritation. In severe cases, excessive
or prolonged breathing of fuel vapor can
cause serious illness and permanent
injury.
• Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses (if worn), flush with
water for 15 minutes and seek medical
attention. Failure to seek proper medical
attention could lead to permanent injury.
• Fuels can be harmful if absorbed through
the skin. If you splash fuel on your skin,
clothing or both, promptly remove
contaminated clothing and thoroughly
wash your skin with soap and water.
Repeated or prolonged skin contact
causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram for
the treatment of alcoholism. Breathing
fuel vapors could cause an adverse
reaction, serious personal injury or
sickness. Immediately call a physician if
you experience any adverse reactions.

FUEL QUALITY
Choosing the Right Fuel
Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in high
altitude areas, offer fuels posted as regular
unleaded gasoline with an octane rating
below 87. The use of these fuels could result
in engine damage that will not be covered
by the vehicle warranty. For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well as
other conditions, for example when towing
a trailer. See Towing (page 256).
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact an
authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal vehicle
and engine performance. For additional
information, refer to www.toptiergas.com.
Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty. Do not use:
•
Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol
or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based additives,
including manganese-based compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl manganese
tricarbonyl (commonly known as MMT), which
is a manganese-based fuel additive, will
impair engine performance and affect the
emission control system.
FUEL FILLER FUNNEL LOCATION
The fuel filler funnel is under the luggage
compartment floor covering.

MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Fuel and RefuelingE161513

RUNNING OUT OF FUEL
Running out of fuel can cause damage not
covered by the vehicle Warranty. If your vehicle runs out of fuel:
•
Add a minimum of 1.3 gal (5 L) of fuel to
restart the engine.
• You may need to switch the ignition from
off to on several times after refueling to
allow the fuel system to pump the fuel
from the tank to the engine. When
restarting, cranking time takes a few
seconds longer than normal.
Note: If your vehicle is on a steep slope,
more fuel may be required.
Filling a Portable Fuel Container WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container. Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an ungrounded
fuel container:
•
Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
• Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).
• Keep the fuel pump nozzle in contact
with the fuel container when filling it.
• Do not use a device that holds the fuel
pump nozzle lever in the fill position.
Adding Fuel From a Portable Fuel
Container WARNING:
Do not insert the nozzle
of a fuel container or an aftermarket funnel
into the fuel filler neck. This may damage
the fuel system filler neck or its seal and
cause fuel to run onto the ground.
