•4X4 LOW- Illuminates when 4L
is selected.
•
- Illuminates when the
electronic locking differential
(ELD) is selected (if equipped).
•CHECK 4X4- Displays when a
4X4 fault is present.
Note:When a 4X4 system fault is present, the system will typically
remain in whichever 4X4 mode was selected prior to the fault condition
occurring. It will not default to 4X2 in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
Using a manual 4WD system (if equipped)
2H (4X2)– Power to the rear
wheels only; used for street and
highway driving. Provides optimal
smoothness and fuel economy at
high speeds.
4H (4X4 High)– Used for extra
traction such as in snow or icy roads
or in off-road situations. Not
intended for use on dry pavement.
N (Neutral)– No power to either
front or rear wheels.
4L (4X4 Low)– Uses extra gearing to provide maximum power to all
four wheels at reduced speeds. Intended only for off-road applications
such as deep sand, steep grades or pulling heavy objects. The shift lever
will not engage 4L (4X4 LOW) until the transmission is in N (neutral)
and the vehicle is moving below 3 mph (5 km/h); this is normal and
should be no reason for concern. Refer toShifting to/from 4L (4X4
Low)for proper operation.
Shifting between 2H (4X2) and 4H (4X4 high)
•Move the transfer case lever between 2H (4X2) and 4H (4X4 High) at
a stop or any forward speed.

Note:Momentarily releasing the accelerator pedal while preforming a
shift will improve engagement/disengagement times.
Note:Do not perform this operation if the rear wheels are slipping.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Note:4X4 High mode is not intended for use on dry pavement.
Shifting to/from 4L (4X4 Low)
1. Bring the vehicle to a speed of 3 mph (5 km/h) or less.
2. Place the transmission in N (Neutral).
3. Move the transfer case lever through N (Neutral) directly to the
desired position.
•If the transfer casewill notengage into 4L (4X4 Low)do not force
the lever.Allow the vehicle to coast at a speed below 3 mph
(5 km/h), then repeat Steps 2 and 3.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Note:4X4 Low mode is not intended for use on dry pavement.
Note:For proper operation in 4X4 Low, ensure the transfer case shift
lever is moved entirely rearward in to the 4L (4X4 Low) position and
that the 4x4 Low light is displayed in the message center.
Note:Ideal 4L (4X4 Low) shift conditions occur when the vehicle is
rolling at a speed below 3 mph (5 km/h) and the transmission is in N
(Neutral).
Using the N (Neutral) position
The transfer case N (Neutral) position overrides the transmission
and puts the vehicle in neutral regardless of transmission
gearshift lever position. The vehicle can move forward or
backward.
This position should only be used when towing the vehicle.
WARNING:Do not leave the vehicle unattended with the
transfer case in the N (Neutral) position. Always set the parking
brake fully and turn off the ignition when leaving the vehicle.

Shifting between 2H (4X2) and 4H (4X4 High)
Move the 4WD control between 2H (4X2) and 4H (4X4 High) at any
forward speed. The message center will display4X4 SHIFT IN
PROGRESSduring the system shift. “4X4 HIGH” will display in the
message center if 4H is selected and “4X2” will momentarily display in
the message center if 2H is selected. .
Note:Momentarily releasing the accelerator pedal while preforming a
shift will improve engagement/disengagement times.
Note:Do not perform this operation if the rear wheels are slipping.
Note:Some noise may be heard as the system shifts or engages; this is

IfSHIFT DELAYED PULL FORWARDis displayed in the message
center, transfer case gear tooth blockage is present. To alleviate this
condition, place the transmission in a forward gear, move the vehicle
forward approximately 5 feet (2 meters), and shift the transmission back
to neutral to allow the transfer case to complete the range shift.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Note:4x4 Low mode is not intended for use on dry pavement.
Using the All Wheel Drive (AWD) system
(if equipped, Harley-Davidson only)
This system includes an electronically controlled transfer case. The
system is interactive with the road, continually monitoring and adjusting
torque delivery to the front and rear wheels to optimize traction.
2H (4X2)- Power to the rear
wheels only; used for street and
highway driving. Provides optimal
smoothness and fuel economy at
high speeds. The message center
will momentarily display “4X2” when
this mode is selected.
AWD (Auto)- Power delivered to
all four wheels, as required, for
increased traction. This is
appropriate for all on-road driving
conditions, such as dry road surfaces, wet pavement, snow, gravel and
shallow sand.
4H (4X4 High)- Used for extra traction on snow covered or icy roads
and in off road situations. This position is not recommended for use on
dry pavement. This position is only intended for severe winter or off-road
conditions, such as deep snow, ice or deep sand. The message center will
display “4X4 High” when this mode is selected.
Shifting between 2H (4X2) and AWD (Auto) or 4H (High)
Move the control from the 2H position to the AWD or 4H position at a
stop or while driving at any forward speed. The message center may
display4X4 SHIFT IN PROGRESSduring the system shift. The message
center will then display “AWD” if AWD has been selected or “4X4 High” if
4H is selected. The message center will momentarily display “4X2” if 2H
has been selected.
Note:4X4 High mode is not intended for use on dry pavement

Shifting between AWD (Auto) and 4H (High)
Move the control from AWD to 4H at a stop or while driving at any
speed. The message center will display “AWD” if AWD has been selected
and “4X4 High” if 4H has been selected
Note:4X4 High mode is not intended for use on dry pavement
Electronic locking differential (ELD) (if equipped)
The electronic locking differential (ELD) is a device housed in the rear
axle which allows both rear wheels to turn at the same speed. The ELD
can provide additional traction should the vehicle become stuck. The
ELD is electronically activated by the driver and can be shifted on the
fly. It is intended for use in mud, rocks, sand, or any off-road condition
where maximum traction is needed. It is not intended for use on dry
pavement.
The ELD is affected by the following conditions:
•The 4WD control must be in either 4H (4X4 High) or 4L (4X4 Low)
mode.
•The ELD will not engage if the vehicle speed is above 20 mph
(30 km/h) in 4X4 High or 56 mph (90 km/h) in 4X4 Low.
•In 4H (4X4 High), the ELD will disengage at speeds above 25 mph
(40 km/h) and will automatically reengage at speeds below 20 mph
(30 km/h).
•In 4L (4X4 Low), the ELD will disengage at speeds above 62 mph
(100 km/h) and will automatically reengage at speeds below 56 mph
(90 km/h).
The ELD is designed for off-road use only and is not intended for use on
dry pavement.

Activating the electronic locking differential (ELD)
The ELD can be turned on by
pulling the knob on the 4WD control
toward you while the control is in
either 4H (4X4 High) or 4L (4X4
Low) mode.
Once the knob is pulled, the
light located on the control will
blink for approximately two seconds
and then it will remain solid.
The
indicator light will also
display in the message center.
Once the
light on the control
remains solid and the
indicator
light is displayed in the message
center, both rear wheel axle shafts
will be locked together providing
added traction.
If the
light blinks for 10 seconds, then turns off, and theindicator
light in the message center turns off, one of the following has occurred:
•The vehicle speed is too high.
•The left and right rear wheel speed difference is too high during an
engagement attempt.
•The system has malfunctioned and will be accompanied by aCHECK
4X4message in the message center.
Note:If the ELD has difficulty disengaging, release the accelerator pedal
and turn the steering wheel in the opposite direction while rolling.
Driving off-road with truck and utility vehicles
4WD vehicles are specially equipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
