NOTE:The Electronic Speed Control System has been
designed to shut down if multiple Electronic Speed
Control switch functions are operated simultaneously in
order to ensure proper operation. If this occurs, the
system can be reactivated by pushing the Electronic
Speed Control switch ON/OFF button and resetting the
desired vehicle SET speed.
To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The automatic transmission may downshift on hills to
maintain the vehicle set speed.
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 SYSTEM — IF EQUIPPED
The Rear Park Assist System provides visible and audible
indications 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 System 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 System can be active only when the
shift lever is in REVERSE. If the Rear Park Assist System
is enabled at this shift lever position, the system will be
active until the vehicle speed is increased to approxi-
mately 11 mph (18 km/h) or above. The system will be
156 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

active again if the vehicle speed is decreased to speeds
less than approximately 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.
