Folding and Tumbling the Seat(s)
{CAUTION:
Automatically folding and tumbling the
seat when someone is sitting in the seat,
could cause injury to the person sitting
there. Always make sure there is no one
sitting in the seat before pressing the
automatic seat release button.
To fold and tumble the seat, do the following:
1. Make sure that there is nothing under, in front
of, or on the seat.
Notice:Folding a rear seat with the safety
belts still fastened may cause damage to the
seat or the safety belts. Always unbuckle
the safety belts and return them to their normal
stowed position before folding a rear seat.2. From the front
seats, press one of
the automatic
seat release buttons
located on the
overhead console.
When accessing the third row seats, if your
vehicle has them, from the outside of the
vehicle, press the button on the panel behind
either rear door.
One press of the button automatically folds the
seatback at and tumbles the seat forward.
There will be a slight delay between the folding
of the seatback and the tumbling of the seat.Overhead Console

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the driver’s
side of the engine compartment, near
the power steering uid reservoir.
3. Plug the cord into a normal, grounded
110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.Automatic Transmission Operation
Your vehicle has a Hydra-Matic®6L80 automatic
transmission, and has an electronic shift
position indicator within the instrument panel
cluster. The electronic shift position indicator
displays when the shift lever is moved out of
PARK (P). SeeFuses and Circuit Breakers
on page 507.
144
There are several different positions for the shift
lever.
PARK (P):This position locks your rear wheels.
It is the best position to use when you start your
engine because your vehicle cannot move easily.
When parked on a hill, especially when the vehicle
has a heavy load, you may notice an increase in the
effort to shift out of PARK (P). See Torque Lock
(Automatic Transmission) underShifting Into
Park (P) on page 152for more information.
{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your vehicle when the engine
is running unless you have to. If you have
left the engine running, the vehicle can
move suddenly. You or others could be
injured. To be sure your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P). See
Shifting Into Park (P) on page 152.Ifyou
are pulling a trailer, seeTowing a Trailer
on page 379.
145
Your vehicle’s transmission uses adaptive shift
controls. Adaptive shift control continually
compares key shift parameters to pre-programmed
ideal shifts stored in the transmissions computer.
The transmission constantly makes adjustments to
improve vehicle performance according to how the
vehicle is being used, such as with a heavy load or
when temperature changes. During this adaptive
shift controls process, shifting may feel different as
the transmission determines the best settings.
When temperatures are very cold, the
Hydra-Matic
®6L80 automatic transmission’s gear
shifting may be delayed providing more stable
shifts until the engine warms up. Shifts may
be more noticeable with a cold transmission. This
difference in shifting is normal.
Driver Shift Control (DSC)
Your vehicle has a Driver Shift Control (DSC). The
DSC controls the vehicle’s transmission and vehicle
speed while driving down hill or towing a trailer by
allowing you to select a desired range of gears.
148
To use this feature, do the following:
1. Move the shift lever to the MANUAL
MODE (M).
2. Press the plus/minus button, to upshift or
downshift selecting the desired range of
gears for your current driving conditions.
When in the MANUAL MODE (M) a number will
display next to the M, indicating the current gear
that has been selected. The DIC display will show
the message MANUAL SHIFT on the rst line and
the current gear will be displayed on the second
line. SeeDriver Information Center (DIC) on
page 245andDIC Operation and Displays on
page 245for more information. The number
displayed in the DIC is the highest gear that can be
used. However, your vehicle can automatically shift
to lower gears as it adjusts to driving conditions.This means that all gears below that number are
available. When FIFTH (5) is selected, FIRST (1)
through FIFTH (5) gears are automatically shifted
by the vehicle, but SIXTH (6) cannot be used until
the plus/minus button located on the steering
column lever is used to change to the gear.
The transmission will prevent a gear range until a
speed that is appropriate for current driving
conditions is achieved. If shifting is prevented for
any reason, the current selected gear will ash
multiple times in the DIC.
Grade Braking is not available when the Driver
Shift Control is active. SeeTow/Haul Mode
on page 150for more information.
While using the DSC, cruise control and the
tow/haul mode can be used.
149
Tow/Haul Mode
Your vehicle has a tow/haul mode. The tow/haul
mode adjusts the transmission shift pattern to
reduce shift cycling, providing increased
performance, vehicle control, and transmission
cooling when towing or hauling heavy loads.
Press the button located on the end of the shift
lever to turn the tow/haul on or off. When the
tow/haul is on, a light on the instrument panel
cluster will come on.SeeTow/Haul Mode Light on page 244for more
information.
Also see “Tow Haul Mode” underTowing a Trailer
on page 379for more information.
The tow/haul mode works with the Autoride
®
feature, if the vehicle has this, to enhance the ride
when trailering or with a loaded vehicle. See
Autoride
®on page 378.
Grade Braking
Grade Braking assists when driving on a downhill
grade. It maintains the vehicle’s speed by
automatically implementing a shift schedule that
uses the engine and the transmission to slow
the vehicle. This reduces wear on the brakes
system and increases control of the vehicle. The
system constantly monitors the vehicle’s speed,
acceleration, throttle position, and whether
the brake pedal is being pressed, and determines
when to keep the current vehicle speed or to
slow down.The system will then automatically
command downshifts that reduces the vehicles
speed, until the brake pedal is no longer
being pressed. This indicates the desired vehicle
speed has been reached.
