increased by pushing up and holding RESUME ACCEL.
Release the Electronic Speed Control lever when the
desired speed is reached, and the new speed will be set.
Tapping RESUME ACCEL once will result ina1mph
(2 km/h) speed increase. Each time the Electronic SpeedControl lever is tapped, speed increases so that tapping
the Electronic Speed Control lever three times will in-
crease speed by 3 mph (5 km/h).
To decrease speed while Electronic Speed Control is ON,
push down and hold SET DECEL. Release the Electronic
Speed Control lever when the desired speed is reached,
and the new speed will be set.
Tapping the SET DECEL lever once will result ina1mph
(2 km/h) speed decrease. Each time the lever is tapped,

NOTE:
•The Electronic 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 Electronic Speed
Control.
REAR PARK ASSIST — IF EQUIPPED
The Rear Park Assist provides visible and audible indi-
cations of the distance between the rear fascia and the
detected obstacle when backing up. Refer to the Warning
Section and Note Section for limitations of this system
and recommendations.
The Rear Park Assist will remember the last system state
(enabled or disabled) from the last ignition cycle when
the ignition is changed to the ON position.The Rear Park Assist can be active only when the shift
lever is in REVERSE. If the Rear Park Assist is enabled at
this shift lever position, the system will be active until the
vehicle speed is increased to approximately 11 mph
(18 km/h) or above. The system will be active again if the
vehicle speed is decreased to speeds less than approxi-
mately 10 mph (16 km/h).
Rear Park Assist Sensors
The four Rear Park Assist Sensors, located in the rear
fascia, monitor the area behind the vehicle that is within
the sensors’ field of view.
The sensors can detect obstacles from approximately 12
to 59 in (30 to 150 cm) from the rear fascia in the
horizontal direction, depending on the location and
orientation of the obstacle and the type of obstacle.

Rear Park Assist Warning Display
The Rear Park Assist Warning Display, located in the
headliner near the flipper glass, provides both visible and
audible warnings to indicate the distance between the
rear fascia and the detected obstacle.When the ignition is turned to the ON position, the
warning display will turn ON all of its LEDs for about
one second. Each side of the warning display has six
yellow and two red LEDs. The vehicle is close to the
obstacle when the red LED is ON.
The system dimly illuminates the two outer most yellow
LEDs when it is ON and detecting no obstacles. The
following chart shows the warning display operation
when the system is detecting an obstacle:

Enable/Disable The Rear Park Assist
The Rear Park Assist can be enabled and disabled with a
switch located on the upper switch bank of the instru-
ment panel. Press the switch once to turn the Rear Park
Assist on, push the switch a second time to
turn the Rear Park Assist off.
124 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

When the switch is pressed to disable the system, the
instrument cluster will display the “PARK ASSIST DIS-
ABLED” message. Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in Section 4 of this manual. When the
shift lever is changed to REVERSE and the system is
disabled, the instrument cluster will actuate a single
chime, once per ignition cycle, and it will display the
message.
The Rear Park Assist Switch LED will be ON when the
Rear Park Assist is disabled or defective. The Rear Park
Assist Switch LED will be OFF when the system is
enabled.
Service The Rear Park Assist
When the Rear Park Assist is defective, the instrument
cluster will actuate a single chime, once per ignition
cycle, and it will display the “SERVICE PARK ASSIST
SYSTEM” message. Refer to “Electronic Vehicle Informa-
tion Center (EVIC)” in Section 4 of this manual. If“SERVICE PARK ASSIST SYSTEM” appears in the EVIC
after making sure the rear fascia/bumper is clean and
free of snow, ice, mud, or other debris, see your autho-
rized dealer.
Cleaning The Rear Park Assist
Clean the Rear Park Assist Sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. Do
not scratch or poke the sensors. Otherwise, you could
damage the sensors.
System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of dirt and debris
to keep the Rear Park Assist System operating prop-
erly.
•Jackhammers, large trucks, and other vibrations could
affect the performance of the Rear Park Assist System.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 125

•When you turn off the Rear Park Assist System, the
instrument cluster will display “PARK ASSIST DIS-
ABLED.” Furthermore, once you turn off the Rear
Park Assist System, it remains off until you turn it on
again, even if you cycle the ignition key.
•When you move the shift lever to the REVERSE
position and the Rear Park Assist System is turned off,
the instrument cluster will display “PARK ASSIST
DISABLED” message for as long as the vehicle is in
REVERSE.
•The Rear Park Assist System, when on, will MUTE the
radio when it is sounding a tone.
•If a Rear Park Assist System malfunction occurs, a
single chime will sound once per ignition cycle. In
addition, the Electronic Vehicle Information Center(EVIC) will display “SERVICE PARK ASSIST SYS-
TEM”. If this occurs making sure the rear fascia/
bumper is free from snow, ice, mud, dirt and debris,
see your authorized dealer.
•Clean the Rear Park Assist Sensors regularly, taking
care not to scratch or damage them. The sensors must
not be covered with ice, snow, slush, mud, dirt, or
debris. Failure to do so can result in the system not
working properly. The system might not detect an
obstacle behind the fascia/bumper, or it could provide
a false indication that an obstacle is behind the fascia/
bumper.
•Objects must not be within 12 in (30 cm) from the rear
fascia/bumper while driving the vehicle. Failure to do
so can result in the system misinterpreting a close
object as a sensor problem, causing the “SERVICE
PARK ASSIST SYSTEM” message to be displayed in
the instrument cluster.
126 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

CAUTION!
•The Rear Park Assist System is only a parking aid
and it is unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs might be
temporarily detected or not detected at all. Ob-
stacles located above or below the sensors will not
be detected when they are in close proximity.
•The vehicle must be driven slowly when using the
Rear Park Assist System to be able to stop in time
when the obstacle is detected. It is recommended
that the driver looks over his/her shoulder when
using the Rear Park Assist System.
WARNING!
•Drivers must be careful when backing up even
when using the Rear Park Assist System. Always
check carefully behind your vehicle, look behind
you, and be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind spots be-
fore backing up. You are responsible for safety and
must continue to pay attention to your surround-
ings. Failure to do so can result in serious injury or
death.(Continued)

WARNING! (Continued)
•Before using the Rear Park Assist System, it is
strongly recommended that the ball mount and
hitch ball assembly is disconnected from the ve-
hicle when the vehicle is not used for towing.
Failure to do so can result in injury or damage to
vehicles or obstacles because the hitch ball will be
much closer to the obstacle than the rear fascia
when the warning display turns on the single
flashing arc and sounds the continuous tone. Also,
the sensors could detect the ball mount and hitch
ball assembly, depending on its size and shape,
giving a false indication that an obstacle is behind
the vehicle.
REAR CAMERA — IF EQUIPPED
Vehicles may be equipped with a rearview camera (lo-
cated on the rear liftgate) that allows you to see an
on-screen image (on the Navigation/Multimedia radio)
of the rear of your vehicle, whenever the vehicle is put
into REVERSE.
WARNING!
Drivers must be careful when backing up even when
using the Rear Camera System. Always check care-
fully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible
for the safety of your surroundings and must con-
tinue to pay attention while backing up. Failure to do
so can result in serious injury or death.
