SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
Note:Do not use snow chains on front tires of Harley-Davidson vehicles.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•Use only SAE Class S chains.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Safety Certification Label and Tire Label:
Base Curb Weight– is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.
Vehicle Curb Weight– is the weight of your new vehicle when you

STARTING
Positions of the ignition
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks the steering wheel,
automatic transmission gearshift
lever and allows key removal. For
vehicles equipped with a manual
transmission, you must depress the
ignition release lever to release the
key.
3. OFF, shuts off the engine and all accessories without locking the
steering wheel. This position also allows the automatic transmission shift
lever to be moved from the P (Park) position without the brake pedal
being depressed.
When the key is in the ignition and in the OFF position, the
automatic transmission shift lever can be moved from the P
(Park) position without the brake pedal depressed. To avoid unwanted
vehicle movement, always set the parking brake.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.

Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
•If the driver’s safety belt is fastened, the
light may not illuminate.
Starting the engine
1. Turn the key to 4 (ON) without
turning the key to 5 (START).
2. Turn the key to 5 (START), then
release the key as soon as the
engine starts. Excessive cranking
could damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to 3 (OFF), wait 10 seconds and try again. If the engine still
fails to start, press the accelerator to the floor and try again; this will
allow the engine to crank with the fuel shut off in case the engine is
flooded with fuel.

N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Overdrive) with Tow/Haul OFF
D (Overdrive) with Tow/Haul OFF is the normal driving position for the
best fuel economy. The overdrive function allows automatic upshifts and
downshifts through gears one through five.
D (Overdrive) with Tow/Haul ON
The Tow/Haul feature improves transmission operation when towing a
trailer or a heavy load. All transmission gear ranges are available when
using Tow/Haul.
To activate Tow/Haul, press the
button on the end of the gearshift
lever.
The TOW HAUL indicator light will
illuminate in the instrument cluster.
Tow/Haul delays upshifts to reduce frequency of transmission shifting.
Tow/Haul also provides engine braking in all forward gears when the
transmission is in the D (Overdrive) position; this engine braking will
slow the vehicle and assist the driver in controlling the vehicle when
descending a grade. Depending on driving conditions and load
conditions, the transmission may downshift, slow the vehicle and control
the vehicle speed when descending a hill, without the accelerator pedal
being pressed. The amount of downshift braking provided will vary based
upon the amount the brake pedal is depressed.
To deactivate the Tow/Haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The TOW HAUL light
will no longer be illuminated.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (Tow/Haul OFF).
Do not use the Tow/Haul feature when driving in icy or slippery
conditions as the increased engine braking can cause the rear
wheels to slide and the vehicle to swing around with the possible loss
of vehicle control..

To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.
3. Start the engine, then press the brake pedal and release the parking
brake.
4. Move the gearshift lever to 1st gear, then slowly release the clutch
pedal while slowly pressing on the accelerator.
During each shift, the clutch pedal must be fully depressed to the floor.
Failure to fully depress the clutch pedal to the floor may cause increased
shift efforts, prematurely wear transmission components or damage the
transmission. Make sure the floor mat is properly positioned so it doesn’t
interfere with the full extension of the clutch pedal.
Do not drive with your foot resting on the clutch pedal or use the clutch
pedal to hold your vehicle at a standstill while waiting on a hill. These
actions will reduce the life of the clutch.
Recommended shift speeds
Do not overspeed the engine when going downhill or steep grades. If
equipped, use the tachometer and do not allow engine speed to exceed
the redline area. Operating the engine beyond the recommended speeds
can cause severe engine damage.
