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 Electronic Speed Control On Hills
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.
Vehicles equipped with a manual transmission may need
to be shifted into a lower gear to climb hills without
speed loss.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your ve-
hicle could go too fast for the conditions, and you
could lose control. An accident could be the result.
Do not use Electronic Speed Control in heavy traffic
or on roads that are winding, icy, snow-covered or
slippery.
REAR PARK ASSIST SYSTEM — IF EQUIPPED
The Rear Park Assist System is a driver aid that senses for
obstacles behind the vehicle and provides both visible
and audible warnings to indicate the range of the object.
158 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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.
•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,
a single chime will sound once per ignition cycle and
the instrument cluster will display “PARK ASSIST
DISABLED.”
•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” and the LED in the Rear Park Assist switch will
illuminate. If this occurs, see your authorized dealer
for service.
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.(Continued)

CAUTION! (Continued)
•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.
•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.
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)
160 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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 the red LEDs ON.
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.
Enabling and Disabling the System
There are times when you may want to disable the Rear
Park Assist System, such as when towing a trailer.
Vehicles Equipped With the Electronic Vehicle
Information Center (EVIC)
You can turn the Rear Park Assist System on or off
through the EVIC. For details, refer to “Personal Settings
(Customer-Programmable Features)” under “Electronic
Vehicle Information Center (EVIC)” in Section 4 of this
manual.

Vehicles Equipped with Rear Park Assist Switch
You can turn the Rear Park Assist System on or off by
pressing the Rear Park Assist switch located the lower
switch bank below the climate controls.System Operation
The system uses four sensors located in the rear bumper
fascia to scan for obstacles up to 79 in (200 cm) away from
the rear bumper fascia. The warning display located
above the rear window provides both visible and audible
warnings to indicate the range of the object.
Rear Park Assist Switch
Rear Park Assist LED Display
162 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The warning display contains two sets of yellow and red
LEDs, one set to warn of obstacles behind the left rear of
the vehicle and the other set to warn of obstacles behind
the right rear of the vehicle. The driver can view the LEDs
either through the rear view mirror or by looking at the
display above the rear window.
When the ignition is turned to the ON position, and the
system is enabled, the warning display will turn on all of
its LEDs for approximately one second. Then, the system
dimly illuminates the two inner most LEDs when it is
detecting no obstacles.The Rear Park Assist System is active when the ignition is
in the ON position, and the system is enabled, and the
driver shifts the transmission into the REVERSE position,
and the vehicle speed is less than 11 mph (18 km/h). The
following chart shows the warning display operation
when the system is detecting an obstacle:

Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will flash in the EVIC display for approximately 10 sec-
onds after a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.
