Automatic Level Control
(if equipped)
Vehicles equipped with automatic level
control will exhibit a whirring sound
under the rear of the vehicle. This is
normal. Under additional rear loads
(passengers or cargo), this sound
Traction Control (if equipped)
The Traction
Control system
activates every
time you start
your vehicle.
When one or
more of the drive wheels begin to spin
from traction loss, the Traction Control
system will apply braking to the spinning
wheel(s) and may reduce engine power
until traction is regained. If your vehicle
becomes stuck, and rocking the vehicle
is required, turn off the system.
Press the button located on the
instrument panel to turn the system off
or back on.
See Section 3 of your Owner Manual.
PERFORMANCE & MAINTENANCE
The RPA system features a different
sequence of warning lights and chimes
than on previous systems.
• When in reverse, a chime will sound
the first time an object is detected if
the object is between 20 inches and
five feet away.
• At five feet, the RPA indicator (located
near the rear dome light) will display
one amber light.
• As you move closer, an additional
amber light will appear.
• A continuous chime will sound and
two amber lights and one red light will
appear when you reach 20 inches or
closer.
To disable Rear Parking Assist, press
the switch located in the overhead
console.
See Section 3 of your Owner Manual.
Note:
The RPA system indicator lights
will flash red if it is not functioning prop-
erly. This condition is most likely caused
by either dirty ultrasonic sensors (locat-
ed on the rear bumper) or if your vehicle
exceeds 3 mph when backing up. Under
certain conditions, such as towing a
trailer, you may want to turn off the rear
parking assist by using the switch on
the overhead console.

System (if equipped)
StabiliTrak is an advanced computer-
controlled vehicle stability enhancement
system that assists with directional con-
trol of the vehicle during sudden maneu-
vers or low traction situations in poor
weather. It is normal to hear the system
working, and the system will automati-
cally disengage cruise control when
activated. StabiliTrak is always on and
fully functional and does not require any
driver input.
