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 key 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 keys; additional coded keys may be
purchased from your authorized dealer. The authorized dealer can
program your spare keys to your vehicle or you can program the keys
yourself. Refer toProgramming spare keysfor instructions on how to
program the coded key.
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.
Anti-theft indicator
The anti-theft indicator is located in
the instrument cluster.
•When the ignition is in the 1 (OFF/LOCK) position, the indicator will
flash once every 2 seconds to indicate the SecuriLock™ system is
functioning as a theft deterrent.
•When the ignition is in the 3 (ON) position, the indicator will glow for
3 seconds, then turn off to indicate normal system functionality.
If a problem occurs with the SecuriLock™ system, the indicator will flash
rapidly or glow steadily when the ignition is in the 3 (ON) position. If this
occurs, the vehicle should be taken to an authorized dealer for service.
Automatic arming
The vehicle is armed immediately
after switching the ignition to the 1
(OFF/LOCK) position.
The theft indicator will flash every
two seconds when the vehicle is
armed.

Automatic disarming
Switching the ignition to the 3 (ON) position with acoded keydisarms
the vehicle.
•The theft indicator will illuminate
for three seconds and then go
out.
•If the theft indicator stays on for
an extended period of time or flashes rapidly, have the system
serviced by your authorized dealer.
Replacement keys
If your keys are lost or stolen and you don’t have an extra coded key,
you will need to have your vehicle towed to an authorized dealer. The
key codes need to be erased from your vehicle and new coded keys will
need to be programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
You can program your own coded keys to your vehicle. Please read and
understand the entire procedure before you begin.
Tips:
•A maximum of eight keys can be coded to your vehicle.
•Only use SecuriLock™ keys.
•You must have two previously programmed coded keys (keys that
already operate your vehicle’s engine) and the new unprogrammed
key(s) readily accessible.
•If no previously programmed coded keys are available, you must take
your vehicle to your authorized dealer to have the spare key(s)
programmed.

GAWR (Gross Axle Weight Rating)– is the maximum allowable
weight that can be carried by a single axle (front or rear).These
numbers are shown on the Safety Compliance Certification Label
located on the B-Pillar or the edge of the driver’s door. The total
load on each axle must never exceed its GAWR.
Note:For trailer towing information refer toTrailer towingfound in
this chapter or theRV and Trailer Towing Guideprovided by your
authorized dealer.
GVW (Gross Vehicle Weight)– is the Vehicle Curb Weight + cargo +
passengers.
GVWR (Gross Vehicle Weight
Rating)– is the maximum
allowable weight of the fully loaded
vehicle (including all options,
equipment, passengers and cargo).
The GVWR is shown on the
Safety Compliance Certification
Label located on the B-Pillar or
the edge of the driver’s door.
The GVW must never exceed the
GVWR.
Exceeding the Safety Compliance Certification Label vehicle
weight rating limits could result in substandard vehicle handling
or performance, engine, transmission and/or structural damage, serious
damage to the vehicle, loss of control and personal injury.

1400 - (2 x 220) - (9 x 100) = 1400 - 440 - 900 = 60 lb. Now you have
the load capacity to transport the cement and your friend home.
In metric units, the calculation would be: 635 kg - (2 x 99 kg) -
(9x45kg)=635-198-405=32kg.
The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Safety Compliance
Certification Label found on the edge of the driver’s door.
TRAILER TOWING
Your vehicle is capable of towing a trailer up to 1,000 lb. (454 kg) gross
trailer weight with a maximum tongue load of 100 lb. (45 kg). Do not
tow a trailer until your vehicle has been driven at least 500 miles (800 km).
Towing a trailer places an additional load on your vehicle’s engine,
transmission, brakes, tires and suspension. Inspect these components
carefully after towing.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized dealer or a
reliable trailer dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.

Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.
All Rear Wheel Drive (RWD) vehicles:
This applies to all cars and 4x2 trucks/sport utilities with rear wheel
drive capability.
•Place the transmission in N (Neutral)
•Maximum speed is 35 mph (56 km/h)
•Maximum distance is 50 miles (80 km)
If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must
be exceeded, you must disconnect the driveshaft. Ford Motor Company
recommends the driveshaft be removed/installed only by a qualified
technician at an authorized dealer. See your authorized dealer for
driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.
