WARNING:The EPS system has diagnostics checks that
continuously monitor the EPS system to ensure proper operation
of the electronic system. When an electronic error is detected, the
message POWER STEERING ASSIST FAULT will be displayed in the
message center. If this happens, stop the vehicle in a safe place, and
turn off the engine. After at least 10 seconds, reset the system by
restarting the engine, and watch the message center for POWER
STEERING ASSIST FAULT. If the message returns, or returns while
driving, take the vehicle to your dealer to have it checked. With the
message displayed, the steering assist is turned off, making the vehicle
harder to steer.
WARNING:If the message SERVICE POWER STEERING is
displayed in the message center, the EPS system has detected a
problem with the system function. On the next key cycle the message
SERVICE POWER STEERING NOW will be displayed and steering
assist will be removed until the steering system is serviced. Have your
vehicle taken to the nearest dealer as soon as possible.
6.2L engine:Your vehicle is equipped with a hydraulic steering system.
To help prevent damage to the power steering system, never hold the
steering wheel at its furthest turning points (until it stops) for more than
a few seconds when the engine is running. If the power steering system
breaks down (or if the engine is turned off), you can steer the vehicle
manually, but it takes more effort.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If excessive, check for low
power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.

PRS (Progressive Range
Selection)
With the gearshift lever in D
(Drive), press the – button to active
PRS. The available and selected
gears will be indicated on the
instrument cluster.
All available gears will be displayed
with the current gear indicated.
Press the – button again to lock out
gears beginning with the highest
gear. Example: press the – button
twice to lock out 6th and 5th gears.
Only the available gears will be
displayed and the transmission will
automatically shift between the
available gears. Press the + button to unlock gears to allow the
transmission to shift to higher gears. The transmission will shift
automatically within the gear range you select.
M (Manual)
With the gearshift lever in M (Manual), the driver can change gears up
or down as desired. This is called SelectShift Automatic™ transmission
(SST) mode. By moving the gearshift lever from drive position D (Drive)
to M (Manual), you now have control of selecting the gear you desire
using buttons on the shift lever. Only the current gear will be displayed.
Press the + button or the – button to upshift or downshift. If the –
button is pressed at a vehicle speed that would cause an engine
overspeed, the requested gear will flash then disappear and the
transmission will remain in the current gear.
To return to normal D (Drive) position, move the shift lever back from M
to D.
The transmission will operate in gears one through six.
Recommended shift speeds
Upshift according to the following chart:
Upshifts when accelerating
Shift from:
1 – 2 15 mph (24 km/h)

The RSS detects obstacles up to
6 feet (2 meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
While receiving a warning the radio
volume may be reduced to a
predetermined level. After the
warning goes away, the radio will return to the previous volume.
The RSS may have reduced performance or an increased chance of false
detection if the tailgate is not locked and in the upright position. If the
tailgate is down, the RSS tone may be heard intermittently or
continuously. The tone may also be heard if items in the truck bed
protrude rearward outside the bed.
The RSS automatically turns on when the gearshift lever is placed in R
(Reverse) and the ignition is on. A control in the message center allows
the driver to disable the system, refer toMessage center and Rear park
aidin theInstrument Clusterchapter for more information.
Note:If the system cannot be turned off, refer toMyKeyrestricted
featuresin theLocks and Securitychapter for more information.
Note:If your vehicle is equipped with a fully integrated electronic trailer
brake controller (TBC) and a trailer with electric trailer brakes is
connected to your vehicle, the RSS will be disabled. When the vehicle is
shifted into reverse, the message center display will remain in the Rear
Park Aid Off selection. For more information on the TBC, refer to the
Tires, Wheels and Loadingchapter.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the

sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
REARVIEW CAMERA SYSTEM (IF EQUIPPED)
The rear video camera system,
located on the tailgate, provides a
video image which appears on the
rearview mirror or touchscreen
display, of the area behind the
vehicle. It adds assistance to the
driver while reversing or reverse
parking the vehicle. To use the rear
video camera system, place the
transmission in R (Reverse). An
image will display on the rearview
mirror or on the touchscreen display. The area displayed on the screen
may vary according to the vehicle orientation and/or road condition.
The rear video camera includes the following features that will assist the
driver in reverse driving.
Fixed guidelines
The fixed guidelines assist a driver with backing into a parking space or
aligning with an object behind the vehicle.
If equipped with touch screen display: To turn this feature on or off
when the vehicle is in R (Reverse), select Settings on the touch screen
display. The fixed guideline options are FIXED and OFF.
If equipped with rearview mirror display and optional instrument cluster:

reverse sensing system to beep. The visual alerts are red, yellow or green
highlights which appear on top of the video image when an object is
detected by the reverse sensing system. The visual alert will highlight
the closest object detected by the reverse sensing system. The reverse
sensing alert can be disabled and if visual park aid alert is enabled,
highlighted areas will still be displayed.

•(3) Yellow zone
•(4) Green zone
•(5) Center line of vehicle
Always use caution while backing. Objects in the red zone (2) are closest
to your vehicle and objects in the green zone (4) are further away. Objects
