NOTE:
Powertrain calibration information is limited to a maximum of five characters per line on the
Vehicle Certification Label. Because of this, calibration identification consisting of more than five
characters will wrap to the second line on the VC label.
Powertrain calibration information is printed in the lower right corner of the Vehicle Certification Label.
Only the base calibration information is printed. Revision levels will not appear, however, this
information can be found in the On Line Automotive Service Information System (OASIS). For the
current model year, Ford Motor Company is using three different protocols which describe powertrain
base calibration. These protocols are designed to provide worldwide standardization for vehicle
calibration. If the electronic calibration strategy has been used since 1998 and carried into the current
model year, protocol 1 will be used. Refer to Protocol 1 below. If the electronic calibration strategy has
been used since 1999 and is carried into the current model year, protocol 2 will be used. Refer to
Protocol 2 below. For new electronic calibration strategies introduced since the 2000 model year, use
protocol 3. Refer to Protocol 3 below.

Unique Calibration
The Emissions/CAFE/CO2 Compliance Department is responsible for assigning these calibration
numbers. Unique calibration identifications are assigned to cover similar vehicles to differentiate tires,
drive configurations, final drive ratios and other calibration- significant factors. 5 Design level (design level assigned to the engine)
Item Description
1 Model year (model year in which calibration strategy was first introduced)
2 Vehicle code
3 Transmission code
4 Unique calibration (designates different hardware to similar vehicles). Example: tires, drive
ratios, etc.
5 Fleet code (describes fleet to which the vehicle belongs). Example: 6 -
evaporative emissions 6 Certification region (lead region where multiple regions are included in one calibration).
Example: A - U.S. federal

These two characters are chosen by the analyst to provide easily identifiable information unique to
each calibration. For example, using the number 2 to denote a two-
valve engine versus using the
number 4 to denote a four- valve engine.

DESCRIPTION AND OPERATION
Jacking
WARNING: Never run the engine with one wheel off the ground, such as when changing a
tire. The wheel still on the ground could cause the vehicle to move.
CAUTION: The jack (17080) provided with the vehicle is intended to be used in an
emergency for changing a deflated tire. To avoid damage to the vehicle, never use the jack to
lift the vehicle for any other purpose. Refer to the Owner Guide when using the jack supplied
with the vehicle.
CAUTION: Under no circumstances should the vehicle ever be lifted by the suspension
arm brackets, rear stabilizer or differential housing or convertible cross brace. Severe damage
to the vehicle could result.
CAUTION: Do not attempt to use jack pressure on either the front bumper (17757) or the
rear bumper (17906) of any vehicle. Damage to the bumper covers will occur.
Lift the vehicle using the Jacking Points procedure in this section.
Jacking Points
To lift the front or either side of the front end, position the floor jack under the front frame lift points. SECTION 100-

DESCRIPTION AND OPERATION
Lifting
CAUTION: Do not allow the lift adapters to contact the steering linkage, suspension arms,
stabilizer arms, or to compress the lower suspension arm stabilizer bar insulator (5493).
Damage to the suspension, exhaust and steering linkage components may occur if care is not
exercised when positioning the hoist adapters prior to lifting the vehicle.
CAUTION: Never use the differential housing as a lift point. Damage to the differential
housing and cover may occur.
CAUTION: Do not lift vehicle on rocker panel pinch flange or convertible cross brace.
Body damage may occur.
Lift the vehicle using the Lifting Points procedure in this section.
Lifting Points—Drive On Lift
CAUTION: To prevent possible damage to the underbody, do not drive the vehicle onto
the drive on lift without first checking for possible interference.
Check for interference between the upright flanges of the hoist rails and the underbody.
If an interference exists, modify the hoist flanges or build up the approach ramps as necessary to
provide clearance. Lifting Points — Frame Contact Lift, Single Post Lift, Two Post Lift SECTION 100-

CAUTION: Do not position lift pads under the No. 3 crossmember.
CAUTION: Do not lift vehicle on rocker panel pinch flange or convertible cross brace.
Body damage may occur.
NOTE: Adapters may be necessary to clear vehicle components to lift the vehicle safely. The adapters
must be placed at the four designated contact points. Position the adapters so they are center on the
adapter contact area.
