Never remove the coolant reservoir cap
while the engine is running or hot. Steam
and scalding liquid from a hot cooling system can
burn you badly.
This gauge indicates the temperature of the engine
coolant, not the coolant level. If the coolant is not at
its proper level the gauge indication will not be
accurate.
Engine oil pressure gauge
Indicates engine oil
pressure. At normal
operating temperature,
the needle will be in
the normal range (the area between the“L”and
“H”); if the needle goes below the normal range,
stop the vehicle as soon as safely possible and
switch off the engine immediately. Check the oil
level. Add oil if needed (refer toEngine oilin the
Maintenance and specificationschapter). If the oil
level is correct, have your vehicle checked at your
dealership or by a qualified technician.
Battery voltage gauge
Indicates battery
voltage. If the pointer
moves and stays
outside the normal
operating range, have the vehicle’s electrical system
checked as soon as possible.
Fuel gauge
Displays approximately
how much fuel is in the
fuel tank. The fuel
gauge may vary slightly
when the vehicle is in motion or on a grade.

The inside lights will not turn off if:
•they have been turned on with the dimmer
control, or
•any door is open.
The battery saver will shut off the interior lamps 30
minutes after the ignition has been turned to the
OFF position, 10 minutes after if the door is left
open, and 30 minutes after if the trunk is left open
or the dome lamp control is left on.
SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLock
passive anti-theft system is an engine
immobilization system. This system is designed to
prevent the engine from being started unless a
coded key programmed to your vehicleis used.
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.
THEFT INDICATOR
The theft indicator is the flashing red indicator
located on top of the instrument panel.
•When the ignition is in the OFF 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 ON position, the
indicator will glow for 3 seconds 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 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 3 (OFF)
position. The
THEFT
indicator in the
instrument cluster will
flash every two
seconds when the vehicle is armed.
Automatic disarming
Switching the ignition to the 4 (ON) position with a
coded keydisarms the vehicle. The
THEFT
indicator will illuminate for three seconds and then
go out. If the
THEFTindicator stays on for an
extended period of time or flashes rapidly, have the
system serviced by your dealership or a qualified
technician.
Key information
Your vehicle is supplied withtwo coded keys.Only
acoded keywill start your vehicle. Spare coded
keys can be purchased from your dealership. Your
dealership can program your key or you can“do it
yourself.”Refer toProgramming spare keys.
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 OFF 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 Fordcoded 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 dealership 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 key
may 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
dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure
before you begin.

1. Insert the first
previously programmed
coded keyinto the
ignition and turn the
ignition from 3 (OFF)
to 4 (ON) (maintain
ignition in 4 (ON) for
at least one second).
2. Turn ignition to 3 (OFF) then 2 (LOCK) and
remove the firstcoded keyfrom the ignition.
3. Within ten seconds of removing the firstcoded
key,insert the second previously programmed
coded keyinto the ignition and turn the ignition
from 3 (OFF) to 4 (ON) (maintain ignition in 4
(ON) for at least one second but no more than ten
seconds).
4. Turn the ignition to 3 (OFF) then 2 (LOCK) and
remove the secondcoded keyfrom the ignition.
5. Within 20 seconds of removing the secondcoded
key,insert the new unprogrammed key (new
key/valet key) into the ignition and turn the ignition
from 3 (OFF) to 4 (ON) (maintain ignition in 4
(ON) for at least one second). This step will
program your new key to a coded key.
6. To program additional new unprogrammed key(s),
repeat this procedure from step 1.
If successful, the new coded key(s) will start the
vehicle’s engine and the theft indicator will
illuminate for three seconds and then go out.
If not successful, the new coded key(s) will not start
the vehicle’s engine and the theft indicator will flash
on and off and you may repeat steps 1 through 6. If
failure repeats, bring your vehicle to your dealership
to have the new spare key(s) programmed.
