Midgate®
{CAUTION:
It can be dangerous to drive with the cargo area
covered and the tailgate and the Midgate®open
because carbon monoxide (CO) gas can come
into your vehicle. You can not see or smell CO.
It can cause unconsciousness and even death.
If you must drive with the cargo covers on and
the tailgate and Midgate
®open or if electrical
wiring or other cable connections must pass
through the seal between the body and the
Midgate
®:
Make sure all windows are shut.
Turn the fan on your heating or cooling
system to its highest speed on the
setting that brings in outside air.
CAUTION: (Continued)
CAUTION: (Continued)
This will force outside air into your
vehicle. SeeDual Automatic Climate
Control System on page 3-24.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-44.
Midgate®Operation
Your vehicle is equipped with a Midgate®and a
removable rear glass panel. The Midgate®allows
you to extend the length of your vehicle’s cargo area.
2-13

PASS-Key®III+ Operation
Your vehicle has PASS-Key®III+ (Personalized
Automotive Security System) theft-deterrent system.
PASS-Key
®III+ is a passive theft-deterrent system.
The system is automatically armed when the key
is removed from the ignition.
The system is automatically disarmed when the key
is turned to ON/RUN, ACC/ACCESSORY or START
from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
If the engine does not start and the security light on
the instrument panel cluster comes on when trying to
start the vehicle, there may be a problem with your
theft-deterrent system. Turn the ignition off and try again.If the engine still does not start, and the key appears
to be undamaged, try another ignition key. At this time,
you may also want to check the fuse, seeFuses
and Circuit Breakers on page 5-107. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may
be faulty. See your dealer/retailer who can service
the PASS-Key
®III+ to have a new key made.
In an emergency, contact Roadside Assistance.
It is possible for the PASS-Key
®III+ decoder to learn
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are
lost or do not operate, you must see your dealer/retailer
or a locksmith who can service PASS-Key
®III+ to
have keys made and programmed to the system.
See your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.

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).
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 2-42for 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). SeeShifting Into PARK (P)
on page 2-42. If you are pulling a trailer,
seeTowing a Trailer on page 4-43.
2-36

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 3-44for more
information.
Also see “Tow Haul Mode” underTowing a Trailer
on page 4-43for 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. SeeAutoride
®on page 4-42.
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.

Storage Areas
Glove Box

Cupholder(s)
Your vehicle has cupholders for the front and rear
passengers.
The cupholders are located in the center console for the
front passengers and on the rear of the center console
for the rear passengers.
To use the front cupholders, press down on the access
door and release. The door will then open. Push the
door back down to close it.
To use the rear cupholders, pull down on the door
located on the back of the console.
The front cupholder may be removed for cleaning
by pushing down and then back on the cupholder.
Instrument Panel Storage
Your vehicle may have a closed storage area on the
instrument panel above the compact disc changer.
You can open the storage area by pressing in the
bottom of the lid and the lid will automatically raise up.
Press down on the lid to close the storage area.
Center Console Storage
Your vehicle has a console compartment between
the bucket seats. The console has both an upper and
lower storage bin that can be opened by lifting up on
the latches located at the front of the console lids.
The console may have an accessory power outlet
inside, seeAccessory Power Outlet(s) on page 3-22.
The rear of the console also has a cupholder that
swings down for the rear seat passengers to use.
