The following items may prevent the vehicle from starting:
•Large metallic objects
•Electronic devices on the key chain that can be used to purchase
gasoline or similar items
•A second key on the same key ring as thecoded key
If any of these items are present, you need to keep these objects from
touching thecoded keywhile starting the engine. These objects and
devices cannot damage thecoded key,but can cause a momentary “no
start” condition if they are too close to the key during engine start. If a
problem occurs, turn ignition to the OFF position and restart the engine
with all other objects on the key ring held away from the ignition key.
Check to make sure thecoded keyis an approved Lincolncoded key.
If your keys are lost or stolen you will need to do the following:
•Use your spare key to start the vehicle, or
•Have your vehicle towed to a authorized dealer or a locksmith. The
key codes will need to be erased from your vehicle and new key codes
will need to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correctcoded keymust be used for your vehicle. The use of the
wrong type ofcoded keymay lead to a “no start” condition.
If an unprogrammed key is used in the ignition it will cause a “no
start” condition.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLock™ keys can be used. To program acoded keyyourself, you
will need two previously programmedcoded keys(keys that already
operate your vehicle’s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your authorized dealer to have the spare coded
key(s) programmed.
Please read and understand the entire procedure before you begin.

•Use the same filling rate setting (low — medium — high) each time
the tank is filled.
•Allow no more than two automatic click-offs when filling.
•Always use fuel with the recommended octane rating.
•Use a known quality gasoline, preferably a national brand.
•Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
•Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in miles or kilometers).
2. Each time you fill the tank, record the amount of fuel added (in
gallons or liters).
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Follow one of the simple calculations in order to determine fuel
economy:
Calculation 1:Divide total miles traveled by total gallons used.
Calculation 2:Multiply liters used by 100, then divide by total
kilometers traveled.
Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.
Driving style — good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
•Steady speeds without stopping will usually give the best fuel
economy.
