Fuel economy may decrease with lower

temperatures.  
Do not measure fuel economy during the  
first 1,000 mi (1,600 km) of driving (this is  
your engines break-in period). A more  
accurate measurement is obtained after  
2,000 mi (3,200 km) to 3,000 mi  
Fuel economy may decrease when  
driving short distances.  
You will get better fuel economy when  
driving on flat terrain than when driving  
on hilly terrain.  
(4,800 km). Also, fuel expense, frequency  
of fill ups or fuel gauge readings are not  
accurate ways to measure fuel economy.  
EMISSION CONTROL SYSTEM  
1. Fill the fuel tank completely and record  
the initial odometer reading.  
WARNINGS  
2. Each time you fill the fuel tank, record  
the amount of fuel added.  
3. After at least three fill ups, fill the fuel  
tank and record the current odometer  
reading.  
Do not park, idle, or drive your vehicle  
in dry grass or other dry ground cover.  
The emission system heats up the  
engine compartment and exhaust system,  
which can start a fire.  
Exhaust leaks may result in entry of  
harmful and potentially lethal fumes  
into the passenger compartment. If  
you smell exhaust fumes inside your  
vehicle, have your dealer inspect your  
vehicle immediately. Do not drive if you  
smell exhaust fumes.  
4. Subtract your initial odometer reading  
from the current odometer reading.  
To calculate L/100 km (liters per 100  
kilometers) fuel consumption, multiply the  
liters used by 100, then divide by kilometers  
traveled. To calculate MPG (miles per  
gallon) fuel consumption, divide miles  
traveled by gallons used.  
Your vehicle is equipped with various  
emission control components and a  
catalytic converter that will enable your  
vehicle to comply with applicable exhaust  
emission standards.  
To make sure that the catalytic converter  
and other emission control components  
continue to work properly:  
Keep a record for at least one month and  
record the type of driving (city or highway).  
This provides an accurate estimate of your  
vehicle's fuel economy under current  
driving conditions. Keeping records during  
summer and winter will show how  
temperature impacts fuel economy.  
Conditions  
Use only the specified fuel listed.  
Avoid running out of fuel.  
Do not turn off the ignition while your  
vehicle is moving, especially at high  
speeds.  
Heavily loading your vehicle reduces  
fuel economy.  
Carrying unnecessary weight in your  
vehicle may reduce fuel economy.  
Adding certain accessories to your  
vehicle such as bug deflectors, rollbars  
or light bars, running boards and ski  
racks may reduce fuel economy.  
Have the items listed in scheduled  
maintenance information performed  
according to the specified schedule.  
Using fuel blended with alcohol may  
lower fuel economy.

The scheduled maintenance items listed  
On-Board Diagnostics (OBD-II)  
in scheduled maintenance information are  
essential to the life and performance of  
your vehicle and to its emissions system.  
Your vehicle has a computer known as the  
on-board diagnostics system (OBD-II) that  
monitors the engines emission control  
system. The system protects the  
If you use anything other than Ford,  
Motorcraft or Ford-authorized parts for  
maintenance replacements or for service  
of components affecting emission control,  
such non-Ford parts should be equivalent  
to genuine Ford Motor Company parts in  
performance and durability.

also assists a service technician in properly  
servicing your vehicle.  
When the service engine soon

system has detected a  
malfunction. Temporary malfunctions may  
cause the service engine soon indicator to  
illuminate. Examples are:

electrical system may be wet.  
You can correct these temporary  
malfunctions by filling the fuel tank with  
good quality fuel, properly closing the fuel  
fill inlet or letting the electrical system dry  
out. After three driving cycles without these  
or any other temporary malfunctions  
present, the service engine soon indicator  
should stay off the next time you start the  
engine. A driving cycle consists of a cold  
engine startup followed by mixed city and  
highway driving. No additional vehicle  
service is required.  
Please consult your warranty information  
for complete details.

If the service engine soon indicator remains  
The OBD-II system checks the emission  
control system during normal driving. A  
complete check may take several days.  
If the vehicle is not ready for I/M testing,  
you can perform the following driving cycle  
consisting of mixed city and highway  
driving:  
1. 15 minutes of steady driving on an  
expressway or highway followed by 20  
minutes of stop-and-go driving with at  
least four 30-second idle periods.  
2. Allow your vehicle to sit for at least  
eight hours with the ignition off. Then,  
start the vehicle and complete the  
above driving cycle. The vehicle must  
warm up to its normal operating  
temperature. Once started, do not turn  
off the vehicle until the above driving  
cycle is complete.  
on, have your vehicle serviced at the first  
available opportunity. Although some  
malfunctions detected by the OBD-II may  
not have symptoms that are apparent,  
continued driving with the service engine  
soon indicator on can result in increased  
emissions, lower fuel economy, reduced  
engine and transmission smoothness and  
lead to more costly repairs.  
Readiness for Inspection and  
Maintenance (I/M) Testing  
Some state and provincial and local  
governments may have  
Inspection/Maintenance (I/M) programs  
to inspect the emission control equipment  
on your vehicle. Failure to pass this  
inspection could prevent you from getting  
a vehicle registration.  
If the vehicle is still not ready for I/M  
testing, you need to repeat the above  
driving cycle.  
If the service engine soon  
indicator is on or the bulb does  
not work, your vehicle may need  
service. See On-Board Diagnostics.  
Your vehicle may not pass the I/M test if  
the service engine soon indicator is on or  
not working properly (bulb is burned out),  
or if the OBD-II system has determined  
that some of the emission control systems  
have not been properly checked. In this  
case, the vehicle is not ready for I/M  
testing.  
If the vehicles engine or transmission has  
just been serviced, or the battery has  
recently run down or been replaced, the  
OBD-II system may indicate that the  
vehicle is not ready for I/M testing. To  
determine if the vehicle is ready for I/M  
testing, turn the ignition key to the on  
position for 15 seconds without cranking  
the engine. If the service engine soon  
indicator blinks eight times, it means that  
the vehicle is not ready for I/M testing; if  
the service engine soon indicator stays on  
solid, it means that your vehicle is ready  
for I/M testing.
