NORMAL (FIXED SPEED) CRUISE
C
ONTROL MODE
In addition to Adaptive Cruise Control mode, a
Normal (Fixed Speed) Cruise Control mode is
available for cruising at fixed speeds. The
Normal (Fixed Speed) Cruise Control mode is
designed to maintain a set cruising speed
without requiring the driver to operate the
accelerator. Speed Control can only be
operated if the vehicle speed is above 20 mph
(32 km/h). To change between the different control modes,
push the Adaptive Cruise Control (ACC) on/off
button which turns the ACC on and the Normal
(Fixed Speed) Cruise Control off. Pushing of the
Normal (Fixed Speed) Cruise Control on/off
button will result in turning on (changing to) the
Normal (Fixed Speed) Cruise Control mode.
To Set A Desired Speed
Turn the Normal (Fixed Speed) Cruise
Control on. When the vehicle has
reached the desired speed, push the
RES (+) or SET (-) button and release.
Release the accelerator and the vehicle will
operate at the selected speed. Once a speed
WARNING!
In the Normal (Fixed Speed) Cruise Control
mode, the system will not react to vehicles
ahead. In addition, the proximity warning
does not activate and no alarm will sound
even if you are too close to the vehicle ahead
since neither the presence of the vehicle
ahead nor the vehicle-to-vehicle distance is
detected. Be sure to maintain a safe distance
between your vehicle and the vehicle ahead.
Always be aware which mode is selected.

STARTING AND OPERATING295
has been set a message “CRUISE CONTROL SET
TO MPH (km/h)” will appear indicating what
speed was set. This light will turn on when the
system is turned on via the on/off control. It
turns green when the cruise control is set.
To Vary The Speed Setting
To Increase Speed
When the Normal (Fixed Speed) Cruise 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. Refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for more
information. The speed increment shown is
dependent on the speed of U.S. (mph) or Metric
(km/h) units:
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 in 5 mph incre -
ments until the button is released. The
increase in set speed is reflected in the instru -
ment cluster display.
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 in 10 km/h
increments until the button is released. The
increase in set speed is reflected in the
instrument cluster display.
To Decrease Speed
When the Normal (Fixed Speed) Cruise 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. Refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for more
information. The speed decrement shown is
dependent on the speed of U.S. (mph) or Metric
(km/h) units:
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
of 1 mph.
If the button is continually pushed, the set
speed will continue to decrease in 5 mph
decrements until the button is released. The
decrease in set speed is reflected in the
instrument cluster display.
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 in 10 km/h
decrements until the button is released. The
decrease in set speed is reflected in the
instrument cluster display.
To Cancel
The following conditions will cancel the Normal
(Fixed Speed) Cruise Control without clearing
the memory:
The brake pedal is applied.
The CANCEL button is pushed.
The Electronic Stability Control/Traction
Control System (ESC/TCS) activates.
5

20_DJD2_OM_EN_USC_t.book Page 295

296STARTING AND OPERATING
The vehicle parking brake is applied.
The braking temperature exceeds normal
range (overheated).
The gear selector is removed from the DRIVE
position.
The driver switches ESC to Full Off mode.
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 Turn Off
The system will turn off and erase the set speed
in memory if:
The Normal (Fixed Speed) Cruise Control on/
off button is pushed.
The ignition is placed in the OFF position.
You engage Four-Wheel Drive Low.
The Adaptive Cruise Control (ACC) on/off
button is pushed.
PARKSENSE REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Rear Park Assist system
provides visual and audible indications of the
distance between the rear fascia and a
detected obstacle when backing up (e.g. during
a parking maneuver). Refer to “ParkSense
System Usage Precautions” in this section for
limitations of this system and
recommendations.
ParkSense will retain the system state (enabled
or disabled) from the previous ignition cycle
when the ignition is placed in the ON/RUN
position.
ParkSense can be active only when the gear
selector is in REVERSE. If ParkSense is enabled
at this gear selector position, the system will
remain active until the vehicle speed is
increased to approximately 7 mph (11 km/h) or
above. When in REVERSE and above the
system's operating speed, a warning will appear
within the instrument cluster display indicating
the vehicle speed is too fast. The system will
become active again if the vehicle speed is
decreased to speeds less than approximately
6 mph (9 km/h).
PARKSENSE SENSORS
The four ParkSense sensors, located in the rear
fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view.
The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depending
on the location, type and orientation of the
obstacle.
NOTE:
If equipped as a dually, the ParkSense system
has six rear sensors to assist in detection
around the dually flares.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display. It provides visual
warnings to indicate the distance between the
rear fascia/bumper and the detected obstacle.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information.
