2015 LINCOLN NAVIGATOR maintenance

BREAKING-IN
You need to break in new tires for approximately 300 miles
(480 kilometers). During this time, your vehicle may exhibit some unique
driving characteristics. Avoid driving too fast during the first 1000 miles
(1600 kilometers). Vary your speed frequently and change up through
the gears early. Do not labor the engine. Do not tow during the first
1000 miles (1600 kilometers).
ECONOMICAL DRIVING
Fuel economy is affected by several things, such as how you drive, the
conditions you drive under and how you maintain your vehicle.
There are some things to keep in mind that may improve your fuel
economy:
•Accelerate and slow down in a smooth, moderate fashion.
• Drive at steady speeds without stopping.
• Anticipate stops; slowing down may eliminate the need to stop.
• Combine errands and minimize stop-and-go driving.
• Close the windows for high-speed driving.
• Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
• Keep the tires properly inflated and use only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled maintenance.
There are also some things you may not want to do because they may
reduce your fuel economy:
• Sudden or hard accelerations.
• Rev the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold mornings.
• Use the air conditioner or front defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while driving.
• Drive a heavily loaded vehicle or tow a trailer.
• Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 pounds [180 kilograms] of weight carried).

GETTING THE SERVICES YOU NEED
Warranty repairs to your vehicle must be performed by an authorized
dealer. While any authorized dealer handling your vehicle line will
provide warranty service, we recommend you return to your selling
authorized dealer who wants to ensure your continued satisfaction.
Please note that certain warranty repairs require special training,
equipment or both, so not all authorized dealers are authorized to perform
all warranty repairs. This means that, depending on the warranty repair
needed, you may have to take your vehicle to another authorized dealer.
A reasonable time must be allowed to perform a repair after taking your
vehicle to the authorized dealer. Repairs will be made using Ford or
Motorcraft parts, or remanufactured or other parts that are authorized by
Ford.

CHANGING A FUSE
Fuses
WARNING:Always replace a fuse with one that has the
specified amperage rating. Using a fuse with a higher amperage
rating can cause severe wire damage and could start a fire.
If electrical components in your
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
FUSE SPECIFICATION CHART
Power Distribution Box
WARNING: Always disconnect the battery before servicing high
current fuses.
WARNING: To reduce risk of electrical shock, always replace the
cover to the power distribution box before reconnecting the
battery or refilling fluid reservoirs.
The power distribution box is located in the engine compartment. It has
high-current fuses that protect your vehicle’s main electrical systems
from overloads.
If the battery has been disconnected and reconnected, see Changing the
Vehicle Battery in theMaintenance chapter.

ENGINE OIL DIPSTICKA.–MIN
B. – MAX
ENGINE OIL CHECK
Refer to the scheduled maintenance information for the appropriate
intervals for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait 15 minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the engine oil level dipstick. See the
Under Hood Overview in this chapter for location of dipstick.
6. Wipe the dipstick clean. Insert the dipstick fully, then remove it again.
If the oil level is between the lower and upper holes or between the MIN
and MAX marks (depending on application), the oil level is acceptable.
DO NOT ADD OIL.
If the oil level is below the lower hole or the MIN mark, add enough oil
to raise the level within the lower and upper holes or within the
MIN-MAX range.
Oil levels above the upper hole or the MAX mark may cause engine
damage. Some oil must be removed from the engine by an authorized
dealer.
7. Put the dipstick back in and ensure it is fully seated.
Adding Engine Oil
Note: Do not remove the engine oil level dipstick or the filler cap when
the engine is running.

Owners Guide gf, 2nd Printing, December 2014
USA (fus)

Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
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 Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Check the engine oil level.
2. If the engine oil level is not within the normal range, add engine oil
that meets Ford specifications. See Capacities and Specificationsfor
more information. Remove the engine oil filler cap and use a funnel to
pour the engine oil into the opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level dipstick.
4. Install the dipstick and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks are heard or until the cap is fully seated.
ENGINE COOLANT CHECK
Checking the Engine Coolant
When the engine is cold, check the concentration and level of the engine
coolant at the intervals listed in the Scheduled Maintenance
Information.
Note: Make sure that the 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.
Note: If the level is at the MIN mark, below the MIN mark, or empty,
add coolant immediately. See Adding Engine Coolantin this chapter.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant concentration should be tested with a
refractometer such as Robinair Coolant and Battery Refractometer
75240. We do not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
