Note:If equipped with Intelligent Access, if the Intelligent Access Key is
within 3 feet (1 meter) of the driver door, your keyless entry keypad
code will still function the same way, but the driver’s door will also
unlock with each keypad button press.
To open the trunk,enter the factory set code or your personal code,
then press the 5•6 control within five seconds.
To lock all doors,press and hold the 7•8 and the 9•0 at the same
time (with the driver’s door closed) for 2 seconds will lock all doors. You
do notneed to enter the keypad code first.
SECURILOCK™ PASSIVE ANTI-THEFT SYSTEM
SecuriLock™ passive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless acoded Integrated Keyhead Transmitter (IKT) or
Intelligent Access Keys programmed to your vehicleis used. The
use of the wrong type of coded key may lead to a “no-start” condition.
Your vehicle comes with two coded Integrated Keyhead Transmitters or
Intelligent Access Keys; additional coded transmitters may be purchased
from your authorized dealer. The authorized dealer can program your
spare transmitters to your vehicle or you can program then yourself.
Refer toProgramming spare Integrated Keyhead Transmitters or
Programming Spare Intelligent Access Keysfor instructions on how to
program the coded key.
For Integrated Keyhead Transmitter (IKT), the Standard SecuriLock™
keys without remote entry transmitter functionality can also be
purchased from your authorized dealer if desired.
Note:The SecuriLock™ passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.
Note:Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded key while starting the engine. These
objects will not cause damage to the coded key, but may cause a
momentary issue if they are too close to the key when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded key and restart the engine.
Note: Do not leave a duplicate coded key in the vehicle. Always
take your keys and lock all doors when leaving the vehicle.

Note:Inspect the wheel pilot hole
prior to installation. If there is
visible corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lugnut/stud holes or
wheel-to-brake surfaces.
RUNNING OUT OF FUEL
If you have run out of fuel and need to refill the vehicle with a portable
fuel container, seeRunning out of fuelin theMaintenance and
Specificationschapter for proper fuel filling method using a portable
fuel container and the included fuel filler funnel.Do notinsert the
nozzle of portable fuel containers or any type of aftermarket funnels into
the Easy Fuel™no capfuel system as it can be damaged. You must use
the included funnel in such circumstances.
WARNING:Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy Fuel™ system. This could
damage the fuel system and its seal, and may cause fuel to run onto
the ground instead of filling the tank, all of which could result in
serious personal injury.
JUMP STARTING
WARNING:The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.

The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
•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.
