Lincoln 2011 MKX - Manual (Page 214)

Absence of the Intelligent Access key: Once the vehicle has started,
the vehicle will remain running until being turned off by the
START/STOP button, even if the IA key is no longer found in the vehicle.
Whenever a door is opened and then closed while the vehicle is running,
the system will search for an IA key inside the vehicle and the message
center will display NO KEY DETECTED if the IA key is no longer
present. This message is a reminder that someone else in the vehicle
may have taken the IA key when exiting the vehicle. If the IA key is no
longer present in the vehicle, you will not be able to re-start your vehicle
outside of the Fast Restart time (see Fast Restart Feature above). It is
important to be aware of where your IA key is located in the vehicle, to
avoid becoming stranded without an IA key.
Your vehicle may have remote start capability. Refer to Remote entry
system in the Locks and Security chapter.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING: If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 1 inch (2.5 cm) or adjust the heating or
air conditioning to bring in fresh air.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
WARNING: Failure to follow engine block heater instructions
could result in property damage or physical injury.
