Notice to owners of pickup trucks and utility type vehicles
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
Before you drive your vehicle, please read this Owner’s Guide carefully.
Your vehicle is not a passenger car. As with other vehicles of this type,
failure to operate this vehicle correctly may result in loss of vehicle
control, vehicle rollover, personal injury or death.
Using your vehicle with a snowplow
For more information and guidelines for using your vehicle with a
snowplow, refer to theDrivingchapter.
Using your vehicle as an ambulance
If your light truck is equipped with the Ford Ambulance Preparation
Package, it may be utilized as an ambulance. Ford urges ambulance
manufacturers to follow the recommendations of theFord Incomplete
Vehicle Manual, Ford Truck Body Builder’s Layout Bookand the
Qualified Vehicle Modifiers (QVM) Guidelinesas well as pertinent
supplements. For additional information, please contact the Truck Body
Builders Advisory Service at http://www.fleet.ford.com/truckbbas/ and
then by selecting “Contact Us” or by phone at 1–877–840–4338.
Use of your Ford light truck as an ambulance, without the Ford
Ambulance Preparation Package voids the Ford New Vehicle Limited
Warranty and may void the Emissions Warranties. In addition, ambulance
usage without the preparation package could cause high underbody
temperatures, overpressurized fuel and a risk of spraying fuel which
could lead to fires.
If your vehicle is equipped with the Ford Ambulance Preparation
Package, it will be indicated on the Safety Compliance Certification
Label. The label is located on the driver’s side door pillar or on the rear
edge of the driver’s door. You can determine whether the ambulance
manufacturer followed Ford’s recommendations by directly contacting
that manufacturer. Ford Ambulance Preparation Package is only available
on certain Diesel engine equipped vehicles.
Using your vehicle as a stationary power source (PTO)
Refer to theDrivingchapter for more information and guidelines for
operating a vehicle equipped with an aftermarket power take-off system.

limitations regarding 911 Assist and Traffic, directions and
Information privacy below). However, parties, such as law
enforcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special equipment is required,
and access to the vehicle or the EDR is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement,
that have such special equipment, can read the information if
they have access to the vehicle or the EDR. Ford Motor Company
and Ford of Canada do not access event data recorder
information without obtaining consent, unless pursuant to court
order or where required by law enforcement, other government
authorities or other third parties acting with lawful authority.
Other parties may seek to access the information independently
of Ford Motor Company and Ford of Canada.
Note: Including to the extent that any law pertaining to Event
Data Recorders applies to SYNCor its features, please note the
following: Once 911 Assist (if equipped) is enabled (set ON), 911
Assist may, through any paired and connected cell phone, disclose
to emergency services that the vehicle has been in a crash
involving the deployment of an airbag or, in certain vehicles, the
activation of the fuel pump shut-off. Certain versions or updates
to 911 Assist may also be capable of being used to electronically
or verbally provide to 911 operators the vehicle location (such as
latitude and longitude), and/or other details about the vehicle or
crash or personal information about the occupants to assist 911
operators to provide the most appropriate emergency services. If
you do not want to disclose this information, do not activate the
911 Assist feature. See your SYNCsupplement for more
information.
Additionally, when you connect to Traffic, Directions and
Information (if equipped, U.S. only) the service uses GPS
technology and advanced vehicle sensors to collect the vehicle’s
current location, travel direction, and speed (“vehicle travel
information”) only to help provide you with the directions, traffic
reports, or business searches your request. If you do not want
Ford or its vendors to receive this information, do not activate
the service. Ford Motor Company and the vendors it uses to
provide you with this information do not store your vehicle travel
information. For more information, see Traffic, Directions and
Information, Terms and Conditions. See your SYNCsupplement
for more information.
