Understanding the shift positions of the 6–speed automatic
transmission (if equipped)
This vehicle is equipped with an adaptive transmission shift strategy.
Adaptive transmission shift strategy offers the optimal transmission
operation and shift quality. When the vehicle’s battery has been
disconnected for any type of service or repair, the transmission will need
to relearn the normal shift strategy parameters, much like having to reset
your radio stations when your vehicle battery has been disconnected.
The adaptive transmission shift strategy allows the transmission to
relearn these operating parameters. This learning process could take
several transmission upshifts and downshifts; during this learning
process, slightly firmer shifts may occur. After this learning process,
normal shift feel and shift scheduling will resume.
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
1. Start the engine
2. Press the brake pedal
3. Move the gearshift lever into the desired gear
To put your vehicle in P (Park):
1. Come to a complete stop
2. Move the gearshift lever and securely latch it in P (Park)
WARNING: Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R (Reverse).Driving

To deactivate the tow/haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The tow/haul light will
no longer be illuminated.
Tow/haul will also deactivate when the vehicle is powered down for a few
minutes.
WARNING: Do not use the tow/haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.
M (Manual) without Overdrive
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
(Overdrive) to M (Manual) you now have control of selecting the gear
you desire using buttons on the shift lever.
To return to normal D (Overdrive) position, move the shift lever back
from M to D.
• The transmission will operate in gears one through six.
2 (Second)
Use 2 (Second) to start-up on slippery roads or to provide additional
engine braking on downgrades.
1 (First)
• Provides maximum engine braking.
• Allows upshifts by moving gearshift lever.
• The transmission will not downshift into 1 (First) at high speeds; it
will downshift to a lower gear and then shift into 1 (First) when the
vehicle reaches slower speeds.
Forced downshifts
• Allowed in D (Overdrive).
• Press the accelerator to the floor.
• Allows transmission to select an appropriate gear.Driving

Recommended shift speeds
Upshift according to the following chart:
Upshifts when accelerating (recommended for best fuel economy)
Shift from: Gasoline engines Diesel engines
1 – 2 15 mph (24 km/h) 12 mph (19 km/h)
2 – 3 25 mph (40 km/h) 19 mph (31 km/h)
3 – 4 40 mph (64 km/h) 26 mph (42 km/h)
4 – 5 45 mph (72 km/h) 34 mph (55 km/h)
5 – 6 50 mph (80 km/h) 46 mph (74 km/h)
In order to prevent the engine from running at too low an RPM, which
may cause it to stall, the SST will still automatically make some
downshifts if it has determined that you have not downshifted in time.
Although the SST will make some downshifts for you, it will still allow
you to downshift at any time as long as the SST determines that the
engine will not be damaged from over-revving.
The SST will not automatically upshift, even if the engine is approaching
the RPM limit. It must be shifted manually by pressing the + button.
Engine damage may occur if excessive engine revving is held
without shifting.
Hill start assist (HSA)
The hill start assist feature makes it easier to pull away when the vehicle
is on a slope without the need to use the parking brake. When the hill
start assist feature is active, the vehicle will remain stationary on the
slope for up to two seconds after you release the brake pedal. During
this time, you have time to move your foot from the brake to the
accelerator pedal and pull away. The brakes are released automatically
once the engine has developed sufficient drive to prevent the vehicle
from rolling down the slope. This is an advantage when pulling away on a
slope; for example from a car park ramp, traffic lights or when reversing
uphill into a parking space.
WARNING: The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and select first or reverse gear.Driving

Using hill start assist
The hill start assist feature is activated automatically when the vehicle is
stopped on a slope greater than five degrees. The hill start assist feature
operates with the vehicle facing downhill if reverse gear is selected. The
hill start assist feature will not operate if the parking brake is activated.
WARNING: You must remain in the vehicle once you have
activated the hill start assist feature.
Activating hill start assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the hill start assist
feature will be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately up to two
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.
WARNING: If the engine is revved excessively, or if a
malfunction is detected when the hill start assist feature is
active, the hill start assist feature will be deactivated.
If Your Vehicle Gets Stuck in Mud or Snow
Note: Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note: Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear. Driving

REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING: To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING: To help avoid personal injury, always use caution
when in reverse and when using the RSS.
WARNING: This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.
WARNING: Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the RSS system may create false beeps.Driving

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 to Message center in the
Instrument Cluster chapter for more information.
Note: If the system cannot be turned off, refer to MyKey™ restricted
features in the Locks and Security chapter 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 Loading chapter. Driving

WARNING: The camera system is a reverse aid supplement
device that still requires the driver to use it in conjunction with
the rear view mirror and the side mirrors for maximum coverage.
WARNING: Objects that are close to either corner of the
bumper or under the bumper, might not be seen on the screen
due to the limited coverage of the camera system.
WARNING: Back up as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.
WARNING: Do not use the camera system with the tailgate
open.
If the back end of the vehicle is hit or damaged, then check with your
authorized dealer to have your rearview camera system checked for
proper coverage and operation.
Night time and dark area use
At night time or in dark areas, the camera system relies on the reverse
lamp lighting to produce an image. Therefore it is necessary that both
reverse lamps are operating in order to get a clear image in the dark. If
either of the lamps are not operating, stop using the camera system, at
least in the dark, until the lamp(s) are replaced and functioning.
Servicing
• If the image comes on while the vehicle is not in R (Reverse), have
the system inspected by your authorized dealer.
• If the image is not clear, then check if there is anything covering the
lens such as dirt, mud, ice, snow, etc. If the image is still not clear
after cleaning, have your system inspected by your authorized dealer.Driving

FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in
this chapter.
When four–wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD can be selected when additional
driving power is desired.
4WD operation is not recommended on dry pavement. Doing so could
result in difficult disengagement of the transfer case, increased tire wear
and decreased fuel economy.
Manual Shift On Stop (MSOS) 4x4 system (if equipped)
The 4WD system is engaged or
disengaged by rotating the control
for both front wheel hub locks from
the FREE or LOCK position, then
manually engaging or disengaging
the transfer case with the
floor-mounted shifter. For increased
fuel economy in 2WD, rotate both
hub locks to the FREE position.
• For proper operation, make
sure that each hub is fully
engaged and that both hub locks are set to the same position
(both set to LOCK or both set to FREE). To engage LOCK,
turn the hub locks completely clockwise; to disengage the hubs
(FREE), turn the hub locks completely counterclockwise.
• The vehicle should not be driven in 4X4 High or 4X4 Low
modes with the hub locks set to FREE as this condition may
damage driveline system components.
• Some vehicles may be equipped with wheel ornaments that cover the
4x4 manual hub lock. These ornaments must be removed to access
the manual hub locks.
Electronic Shift-On-the-Fly (ESOF) 4x4 system (if equipped)
If equipped with the electronic shift 4WD system, and 4X4 Low is
selected while the vehicle is moving above 3 mph (5 km/h), the
4WD system will not perform a shift. This is normal and should be
no reason for concern. Refer to Shifting to/from 4L (4X4 Low) for
proper system operation. Driving
