Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied the cruise control is
disengaged.Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal;
when cruise control disengages,
the indicator light will not be lit.
.Press*.
.Press1to turn the cruise
control system off completely.
The cruise control cannot be
resumed.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
1
or if the vehicle is turned off.
Object Detection
Systems
Ultrasonic Parking Assist
If available, the Ultrasonic Front and
Rear Parking Assist (UFRPA)
system assists the driver with
parking and avoiding objects.
UFRPA operates at speeds less
than 8 km/h (5 mph). The sensors
on the front and rear bumper detect
objects up to 1.2 m (4 ft) in front of
the vehicle, 2.5 m (8 ft) behind the
vehicle, and at least 25 cm (10 in)
off the ground.

{WARNING
The Ultrasonic Front and Rear
Parking Assist (UFRPA) system
does not replace driver vision.
It cannot detect:
.Objects that are below the
bumper, under the vehicle,
or too close or far from the
vehicle.
.Children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before moving forward and while
backing up, vehicle damage,
injury, or death could occur. Even
with UFRPA, always check in
front of the vehicle before moving
forward and behind the vehicle
before backing up. While moving
forward and backing up, be sure
to look for objects and check the
vehicle mirrors.
How the System Works
When the vehicle is shifted into
R (Reverse) the front and rear
sensors are automatically turned on.
After the vehicle is shifted out of
R (Reverse), the rear sensors are
turned off and the front sensors stay
on until the vehicle is above a
speed of 8 km/h (5 mph). For the
front park assist system to be active
again without shifting into
R (Reverse), the park assist button
in the overhead console must be
pressed. See “Turning the System
On and Off” later in this section.
UFRPA operates only at speeds
less than 8 km/h (5 mph).
When the vehicle is in N (Neutral),
the system may be active. If the
vehicle is in a car wash, the sensors
may detect objects in the car wash.
See “Turning the System On and
Off” later in this section to turn the
system off. High-toned beeps from the front
speakers are for objects detected
near the front bumper. Low-toned
beeps from the rear speakers are
for objects detected near the rear
bumper. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
To be detected, objects must be at
least 25 cm (10 in) off the ground
and below hatch level. Objects must
also be within 1.2 m (4 ft) in front of
the vehicle and 2.5 m (8 ft) from the
rear bumper. This distance may be
less during warmer or humid
weather.

Objects Detected by Both the
Front and Rear Sensors
In general, if objects are detected at
the same time near both the front
and rear bumpers while backing up,
the beeps only sound to indicate
that objects are close to the rear
bumper.
However, if an object comes within
0.3 m (1 ft) of the front bumper while
the vehicle is backing up and at the
same time there is another object
further than 0.3 m (1 ft) from the rear
bumper, then the beeps only sound
to indicate the object that is closer
to the front bumper.Turning the System On and Off
The UFRPA system can be turned
on and off by pressing the park
assist button located in the
overhead console.
The LED next to the park assist
button lights up when the system is
on and turns off when it has been
disabled.
When the system is off, PARK
ASSIST OFF displays on the Driver
Information Center (DIC). The
message disappears after a short
period of time.
UFRPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST:If
this message occurs, take the
vehicle to your dealer to repair the
system.
PARK ASSIST OFF: If the UFRPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
.The driver has disabled the
system.
.The ultrasonic sensors are not
clean. Keep the vehicle's
bumpers free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑85.
