Engine Coolant - Lincoln 2011 MKX Owner's Manual

Maintenance and Specifications
Battery management system
The Battery Management System (BMS) monitors battery conditions and
takes actions to extend battery life. With the engine off, the audio system
may turn off due to low battery state of charge conditions or the ignition
has been in accessory position or on position with the engine off for
approximately 45 minutes. A message may be displayed on the
instrument cluster or center stack display to alert the driver that battery
protection actions are active. See the Message Center in the Instrument
Cluster section and Entertainment Systems section for more
information. These messages are only for notification that an action is
taking place, and do not necessarily indicate that an electrical problem
exists or that the battery requires replacement.
Electrical accessory installation
To ensure proper operation of the BMS, any electrical devices that are
added to the vehicle should not have their ground connection made
directly at the negative battery post. A connection at the negative
battery post can cause inaccurate measurements of the battery condition
and potential incorrect system operation.
Note: Electrical or electronic accessories added to the vehicle may
adversely affect battery performance and durability and may also affect
the performance of other electrical systems in the vehicle.
When a battery replacement is required, the battery should only be
replaced with a Ford recommended replacement battery that matches
the electrical requirements of the vehicle.

ENGINE COOLANT

Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed in scheduled maintenance information. The coolant
concentration should be maintained at 50/50 coolant and distilled water.
Coolant concentration testing is possible with a hydrometer or antifreeze
tester. The level of coolant should be maintained at the FULL COLD
level or within the COLD FILL RANGE in the coolant reservoir. If the
level falls below, add coolant per the instructions in the Adding engine
coolant section.
