STARTING AND OPERATING279
NOTE:
Always store the remote control in a protected,
clean, dry area.
RIGGING TECHNIQUES
Various winching situations will require
application of other winching techniques. These
could range from too little distance to achieve
maximum pull using straight line rigging, simply
increasing pulling power, or maintaining a
straight-line pulling situation. You will have to
assess what technique is correct for your
situation. Think "safety" at all times.
How To Change The Pulling Direction

Change Pulling Directions

All winching operations should have a straight
line from the winch to the object being pulled. This minimizes the synthetic rope collecting on
one side of the drum affecting pulling efficiency
and damaging synthetic rope. A snatch block,
secured to a point directly in front of the vehicle
will enable you to change your pulling direction
while still allowing the synthetic rope to be at
90° to wind properly onto the spooling drum.
Increasing Pulling Power
In some cases, you may find yourself needing
more pulling power. The use of snatch blocks
increases mechanical advantage and that
increases your pulling power.
Double Line

Wire Rope Routing

Because pulling power decreases with the
number of layers of synthetic rope on the winch drum, you can use a snatch block to double line
out more rope. This decreases the number of
layers of synthetic rope on the drum, and
increases pulling power. Start by feeding out
enough synthetic rope to free the winch hook.
Attach the hook to your vehicle's frame/tow
hook and run the rope through a snatch block.
Disengage the clutch and, using the snatch
block, pull out enough synthetic rope to reach
your anchor point. Do not attach the hook to the
mounting kit. Secure to the anchor point with a
tree trunk protector or choker chain. Attach the
clevis/shackle. Attach the shackle to the two
ends of the strap/chain, being careful not to
over tighten (tighten and back-off 1/2 turn).
FUEL SAVER TECHNOLOGY — GAS ENGINE
(IF EQUIPPED)
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
This system may take some time to return to full
functionality after a battery disconnect.

280STARTING AND OPERATING
SPEED CONTROL
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
20 mph (32 km/h), or 25 mph (40 km/h),
depending on the powertrain used.
The Speed Control buttons are located on the
right side of the steering wheel.

Speed Control Buttons

NOTE:
In order to ensure proper operation, the Speed
Control system has been designed to shut down if multiple speed control functions are operated
at the same time. If this occurs, the Speed
Control system can be reactivated by pushing
the Speed Control on/off button and resetting
the desired vehicle set speed.
TO ACTIVATE
Push the on/off button to activate the Speed
Control. The cruise indicator light in the
instrument cluster display will illuminate. To
turn the system off, push the on/off button a
second time. The cruise indicator light will turn
off. The system should be turned off when not in
use.
TO SET A DESIRED SPEED
Turn the Speed Control on. When the vehicle
has reached the desired speed, push the SET (-)
button and release. Release the accelerator and the vehicle will operate at the selected
speed.
NOTE:
The vehicle should be traveling at a steady
speed and on level ground before pushing the
SET (-) button.
TO VARY THE SPEED SETTING
To Increase Speed
When the Speed Control is set, you can increase
speed by pushing the RES (+) button.

The driver’s preferred units can be selected
through the instrument panel settings (if
equipped). Refer to “Getting To Know Your
Instrument Panel” for more information. The
speed increment shown is dependent on the
chosen speed unit of U.S. (mph) or Metric (km/h):

U.S. Speed (mph)

Pushing the RES (+) button once will result in
a 1 mph increase in set speed. Each subse -
quent tap of the button results in an increase
of 1 mph.
If the button is continually pushed, the set
speed will continue to increase until the
button is released, then the new set speed
will be established.
1 — On/Off Button
2 — RES (+)
3 — SET (-)
4 — CANCEL
WARNING!
Leaving the Speed Control system on when
not in use is dangerous. You could
accidentally set the system or cause it to go
faster than you want. You could lose control
and have an accident. Always leave the
system off when you are not using it.

20_DJD2_OM_EN_USC_t.book Page 280

282STARTING AND OPERATING
(Continued)
The following conditions will also deactivate the
Speed Control without erasing the set speed
from memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
ADAPTIVE CRUISE CONTROL (ACC) — IF
EQUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise control
while traveling on highways and major
roadways. However, it is not a safety system
and not designed to prevent collisions. Speed
Control function performs differently. Please
refer to the proper section within this chapter.
ACC will allow you to keep cruise control
engaged in light to moderate traffic conditions
without the constant need to reset your cruise
control. ACC utilizes a radar sensor and a
forward facing camera designed to detect a
vehicle directly ahead of you. NOTE:
If the sensor does not detect a vehicle ahead
of you, ACC will maintain a fixed set speed.
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accelerate
(not to exceed the original set speed) auto
-
matically to maintain a preset following
distance, while matching the speed of the
vehicle ahead.
The Cruise Control system has two control
modes:
Adaptive Cruise Control mode for main -
taining an appropriate distance between
vehicles.
Normal (Fixed Speed) Cruise Control mode
for cruising at a constant preset speed. For
additional information, refer to “Normal
(Fixed Speed) Cruise Control Mode” in this
section.
NOTE:
Normal (Fixed Speed) Cruise Control will not
react to preceding vehicles. Always be aware of
the mode selected. You can change the mode by using the Cruise
Control buttons. The two control modes
function differently. Always confirm which mode
is selected.
WARNING!
Adaptive Cruise Control (ACC) is a conve
-
nience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions,
vehicle speed, distance to the vehicle
ahead; and, most importantly, brake opera -
tion to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle.
Failure to follow these warnings can result
in a collision and death or serious personal
injury.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
