•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. For additional information, refer toAutomatic
transmission operationin theDrivingchapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•Practice turning, stopping and backing-up before starting on a trip to
get the feel of the vehicle-trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 6 in. (15 cm) above the
bottom edge of the rear bumper.

AUTOMATIC TRANSMISSION OPERATION
Automatic transmission adaptive learning
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
Understanding the gearshift positions of the 6–speed automatic
transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
P (Park)
This position locks the transmission
and prevents the front wheels from
turning.
To put your vehicle in gear:
1. Press the brake pedal.
2. 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).
N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
D (Drive) with Overdrive
The normal driving position for the best fuel economy. Transmission
operates in gears one through six.
D (Drive) with Grade Assist
Pressing the transmission control
switch on the side of the gearshift
lever activates grade assist and
cancels overdrive.
•Provides additional grade
(engine) braking and extends
lower gear operation on uphill
climbs for hilly terrain or
mountainous areas.
•Provides additional engine
braking through the automatic
transmission shift strategy which
reacts to vehicle inputs (vehicle
acceleration, accelerator pedal,
brake pedal and vehicle speed).
•Allows the transmission to select
gears that will provide the desired engine braking based on the vehicle
inputs mentioned above. This will increase engine RPM during engine
braking.

•The grade assist lamp in the
instrument cluster is illuminated.
Grade assist is designed to aid the
driver with optimal gear selection in
hilly terrain or mountainous areas
but is not intended for normal operation. It is recommended that you
return to O/D (overdrive mode) on flat terrain to provide the best fuel
economy and transmission function.
To return to normal D (Drive) position (with O/D), press the
transmission control switch again.
•The grade assist lamp in the instrument cluster will not be illuminated.
•The transmission will operate in gears one through six.
O/D (overdrive mode) is automatically returned each time the engine is
turned off.
L (Low)
•Provides maximum engine braking.
•Will downshift to the lowest available gear for the current vehicle
speed; allows for first gear when vehicle reaches slower speeds.
If your vehicle gets stuck in mud or snow
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.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when 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.
Driving

Owners Guide, 2nd Printing
USA(fus)

Note:If the system cannot be turned off, refer toMyKey™in theLocks
and Securitychapter for more information.
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 rearview camera system located
on the liftgate provides a video
image, which appears in the
rearview mirror or on the navigation
screen (if equipped), of the area
behind the vehicle. It adds
assistance to the driver while
reversing or reverse parking the
vehicle.
To use the camera, place the transmission in R (Reverse); an image will
display on the left portion of the rearview mirror or on the navigation
screen (if equipped). The area displayed on the screen may vary
according to the vehicle orientation and/or road condition.
•(1) Rear bumper
•(2) Red zone
•(3) Yellow zone
•(4) Green zone
•(5) Centerline of vehicle
Always use caution while backing.
Objects in the red zone are closest
to your vehicle and objects in the
green zone are further away. Objects
are getting closer to your vehicle as they move from the green zone to
the yellow or red zones.
Use the side mirrors and rearview mirror to get better coverage on both
sides and rear of the vehicle.
