CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Harley-Davidson vehicles are equipped with a spare tire with a different
speed rating than the road tires. It is not recommended that you exceed
112 km/h (70 mph) when the spare tire is in use. Though the spare tire
is rated for 112 km/h (70 mph), always obey the local speed limits.

Tire change procedure
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
Refer to the instruction sheet (located with the jack) for detailed tire
change instructions.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park)
(automatic transmission) or in the
reverse gear (manual
transmission)and turn engine OFF.
3. Block the diagonally opposite
wheel.
4. Obtain the spare tire and jack
from their storage locations.
5. Use the tip of the lug wrench to
remove any wheel trim.

6. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
7. Position the jack according to the following guides and turn the jack
handle clockwise until the wheel is completely off the ground.
When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park) or in the reverse gear
(manual transmission). To prevent the vehicle from moving when you
change the tire, be sure that the parking brake is set and the
diagonally opposite wheel is blocked. If the vehicle slips off the jack,
someone could be seriously injured.

Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the positive (+) terminal of
the discharged battery.

assisting (boosting) battery.

PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jam) to
your dealer to ensure you get the correct color.
•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND COVERS
Aluminum wheel rims or covers are coated with a clearcoat paint finish.
In order to maintain their shine:
•Clean weekly with Motorcraft Wheel and Tire Cleaner (ZC-37–A),
which is available from your dealer. Heavy dirt and brake dust
accumulation may require agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•Never apply any cleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use Ford Extra Strength Tar and Road Oil
Removal (B7A-19520–AA), available from your dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
•Cover the highlighted areas to prevent water damage when cleaning
the engine.
