DATA RECORDING
Service Data Recording
Service data recorders in your vehicle are capable of collecting and
storing diagnostic information about your vehicle. This potentially
includes information about the performance or status of various systems
and modules in the vehicle, such as engine, throttle, steering or brake
systems. In order to properly diagnose and service your vehicle, Ford
Motor Company, Ford of Canada, and service and repair facilities may
access or share among them vehicle diagnostic information received
through a direct connection to your vehicle when diagnosing or servicing
your vehicle. For U.S. only (if equipped), if you choose to use the SYNC
Vehicle Health Report, you consent that certain diagnostic information
may also be accessed electronically by Ford Motor Company and Ford
authorized service facilities, and that the diagnostic information may be
used for any purpose. See yourSYNCsupplement for more information.
CELL PHONE USE
The use of mobile communications equipment has become increasingly
important in the conduct of business and personal affairs. However,
drivers must not compromise their own or others’ safety when using
such equipment. Mobile communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile communication equipment includes, but is not limited to, cellular
phones, pagers, portable email devices, text messaging devices and
portable two-way radios.
WARNING:Driving while distracted can result in loss of vehicle
control, accident and injury. Ford strongly recommends that you
use extreme caution when using any device or feature that may take
your focus off the road. Your primary responsibility is the safe
operation of your vehicle.
We recommend against the use of any handheld device while driving
and that you comply with all applicable laws.

Charging system:Illuminates when
the battery is not charging properly.
If it stays on while the engine is
running, there may be a malfunction
with the charging system or a related component. Contact your
authorized dealer as soon as possible.
Check fuel cap (gasoline engine
only):Illuminates when the fuel cap
may not be properly installed.
Continued driving with this light on
may cause the service engine soon
warning indicator to illuminate.
Check suspension (if equipped):
Illuminates when the air suspension
dump switch has been activated.

detected and shifting may be
restricted. Depending upon the
severity of the problem, the
read-out digit on the shifter display
may be blank.
On MD 3000 series transmissions,operation may continue in order to
reach service assistance. The ECU may not respond to shift selector
requests, since operating limitations are being placed on the
transmission, i.e. upshifts and downshifts may be restricted. Direction
changes do not occur.
Refer to your transmission operator’s manual for more information.
Diesel exhaust fluid (diesel
engine only):Illuminates when the
diesel exhaust fluid level falls below
0.5 gallon (1.9L) in the 5 gallon
