If your vehicle is equipped with a tire pressure monitoring
system, refer toTire Pressure Monitoring System (if
equipped)in theMaintenance and specificationssection for
important information. If the tire pressure monitor sensor becomes
damaged, it will no longer function.
Spare tire information
Failure to follow these guidelines could result in an increased
risk of tire failure, loss of vehicle control, injury or death.
Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in diameter and/or width from the road tires and wheels listed
on the vehicle’s certification label or the tire label. If you have a
dissimilar spare tire/wheel, then it is intended for temporary use only.
This means that if you need to use it, you should replace it as soon as
possible with a road tire/wheel that is the same size and type as the road
tires and wheels that were originally provided by Ford. If the dissimilar
spare tire or wheel is damaged, it should be replaced rather than
repaired.
When driving with the dissimilar spare tire/wheeldo not:
•Use more than one dissimilar spare tire/wheel at a time
•Use commercial car washing equipment
•Use snow chains on the end of the vehicle with the dissimilar spare
tire/wheel
The usage of a dissimilar spare tire/wheel can lead to impairment of the
following:
•Handling, stability and braking performance
•Trailer tow performance
•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
Drive cautiously when using a dissimilar spare tire/wheel and seek
service as soon as possible.
Note:If your vehicle is equipped with the tire pressure monitoring
system, the system indicator light will illuminate when the spare is in

•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
