Spare tire information
Note:If your vehicle is equipped the tire pressure monitoring system
(TPMS), the system indicator light will illuminate when the spare is in
use. To restore the full functionality of the TPMS system, all road wheels
equipped with the tire pressure monitoring sensors must be mounted on
the vehicle.
If your vehicle is equipped with TPMS, have a flat tire serviced by an
authorized dealer in order to prevent damage to the TPMS sensor; refer to
Tire Pressure Monitoring System (TPMS)in theTires, Wheel and Loading
chapter. Replace the spare tire with the road tire as soon as possible.
T-type/Mini-spare tire information (Harley-Davidson only)
Your vehicle may be equipped with a temporary spare tire. This spare
tire is considered “temporary”. Replace the temporary spare with a tire
of the same size, speed rating, and load carrying capacity as the other
road tires as soon as possible.

Roadside Emergencies
309

•Idling for long periods of time (greater than one minute) may waste
fuel.
•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•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 toMaintenance Product
Specifications and Capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle’sscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] 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.
