STARTING AND OPERATING273
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.
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.
1 — On/Off Button
2 — RES (+)
3 — SET (-)

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.
Metric Speed (km/h)
Pushing the RES (+) button once will result in
a 1 km/h increase in set speed. Each subse -
quent tap of the button results in an increase
of 1 km/h.
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.
To Decrease Speed
When the Speed Control is set, you can
decrease speed by pushing the SET (-) 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 decrement shown is dependent on the
chosen speed unit of U.S. (mph) or Metric
(km/h):
U.S. Speed (mph)
Pushing the SET (-) button once will result in
a 1 mph decrease in set speed. Each subse -
quent tap of the button results in a decrease

button is released, then the new set speed
will be established.
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 274

STARTING AND OPERATING275
Metric Speed (km/h)
Pushing the SET (-) button once will result in
a 1 km/h decrease in set speed. Each subse -
quent tap of the button results in a decrease
of 1 km/h.
If the button is continually pushed, the set
speed will continue to decrease until the
button is released, then the new set speed
will be established.
To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Speed Control system maintains speed up
and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain may
occur so it may be preferable to drive without
Speed Control.
To Resume Speed
To resume a previously set speed, push the RES
(+) button and release. Resume can be used at
any speed above 20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the
CANCEL button, or normal brake pressure while
slowing the vehicle will deactivate the Speed
Control without erasing the set speed from
memory.
Pushing the on/off button, or placing the igni -
tion in the OFF position, erases the set speed
from memory. 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 road
-
ways. 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.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the
conditions, and you could lose control and
have an accident. Do not use Speed Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

276STARTING AND OPERATING
(Continued)
(Continued)
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 func
-
tion differently. Always confirm which mode is
selected.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for
active driving 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).
Cannot take street, traffic, and weather conditions into account, and may be
limited upon adverse sight distance
conditions.
Does not always fully recognize complex driving conditions, which can
result in wrong or missing distance
warnings.
Will bring the vehicle to a complete stop while following a target vehicle and hold
the vehicle for approximately two
seconds in the stop position. At this
point, there will be an “ACC may cancel
soon” chime and warning to the driver.
When ACC is cancelled, the system will
release the brakes and the driver must
take over braking. The system can be
resumed when the target vehicle drives
off by releasing the brake and pushing
the resume button on the steering
wheel.
