STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and
reduce emissions. The system will stop the engine auto-
matically during a vehicle stop if the required conditions
are met. Releasing the brake pedal will automatically
re-start the vehicle.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. It will remain in STOP/START
NOT READY until you drive forward with a vehicle
speed greater than 5 mph (8 km/h). At that time, the
system will go into STOP/START READY and if all other
conditions are met, can go into an STOP/START AUTO
STOP ACTIVE “Autostop” mode.To Activate The Autostop Mode, The Following Must
Occur:
1. The system must be in STOP/START READY state. A
STOP/START READY message will be displayed in
the Electronic Vehicle Information Center (EVIC)
within the Stop/Start section. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understand-
ing Your Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in Drive and the brake pedal depressed.
The engine will shut down, the tachometer will move to
the zero position and the stop/start telltale will illumi-
nate indicating you are in an Autostop. While in an5

To Start The Engine While In Autostop Mode
While in DRIVE the engine will start when the brake
pedal is released or the throttle pedal is depressed. The
transmission will automatically reengage upon engine
restart. During this transition the brakes will hold the
vehicle to avoid undesired vehicle movement.
Conditions that will cause the engine to start automati-
cally while in Autostop mode.
The Engine Will Start Automatically When:
•The transmission selector is moved from DRIVE to
REVERSE or NEUTRAL
• To maintain cabin temperature near the HVAC settings
• HVAC is set to full defrost mode
• Autostop time exceeds 5 minutes
• Battery voltage drops too low •
Low brake vacuum (e.g. after several brake pedal
applications)
• STOP/START OFF switch is pressed
• 4WD system is put into 4LO mode
• The emissions system requires it
• A STOP/START system error occurs
Conditions that force an automatic shift to PARK while
in Autostop mode.
The Engine Will Not Start Automatically and the Trans-
mission will be placed in PARK if:
• The driver door is open and brake pedal released
• The driver door is open and the driver seat belt is
unbuckled
• The engine hood has been opened
• A STOP/START system error occurs

The engine block heater cord is routed through the grille
by the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not
in use for the winter months. During winter months,
remove the heater cord wiring assembly from itself on
the c-clip.
The engine block heater must be plugged in at least one
hour to have an adequate warming effect on the engine.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
• Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
• Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
394 STARTING AND OPERATING

In 8-speed vehicles, the brake pedal must also be pressed
to shift from NEUTRAL into DRIVE or REVERSE when
the vehicle is stopped or moving at low speeds.
Eight-Speed Automatic Transmission — If
Equipped
The transmission is controlled using a rotary electronic
gear selector located on the instrument panel. The trans-
mission gear range (PRND) is displayed both above the
gear selector and in the Electronic Vehicle Information
Center (EVIC). To select a gear range, simply rotate the
gear selector. You must press the brake pedal to shift the
transmission out of PARK, or to shift from NEUTRAL
into DRIVE or REVERSE, when the vehicle is stopped or
moving at low speeds (refer toBrake/Transmission Shift
Interlock System in this section). To shift past multiple
gear ranges at once (such as Park to Drive), simply rotate
the gear selector to the appropriate detent. Select the
DRIVE range for normal driving. The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission gear selector has only PARK, RE-
VERSE, NEUTRAL, and DRIVE positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) switches (described later in this section). Pressing
the GEAR-/GEAR+ switches (on the steering wheel)
while in the DRIVE position will select the highest
available transmission gear, and will display that gear in
the instrument cluster as 1, 2, 3, etc.

Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies” for
further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE provides optimum driving characteristics under
all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Electronic Range
Select (ERS) switches (refer to Electronic Range Select(ERS) Operation
in this section) to select a lower gear
range. Under these conditions, using a lower gear range
will improve performance and extend transmission life
by reducing excessive shifting and heat buildup.
During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and

transmission is in DRIVE. For example, if you shift the
transmission into 3 (third gear), the transmission will not
shift above third gear (except to prevent engine over-
speed), but will shift down into second and first gears
normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in DRIVE, the
transmission will operate automatically, shifting between
all available gears. Tapping the GEAR- switch (on the
steering wheel) will activate ERS mode, display the
current gear in the instrument cluster, and maintain that
gear as the top available gear. Once in ERS mode, tapping
the GEAR- or GEAR+ switch will change the top avail-
able gear.To exit ERS mode, simply press and hold the GEAR+
switch until “D” is once again displayed in the instru-
ment cluster.

desired, the switch must be pressed each time the engine
is started.
Six-Speed Automatic Transmission — 1500
Models Only (If Equipped)
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
The shift lever is mounted either on the right side of the
steering column (if equipped) or on the console (if
equipped). You must press the brake pedal to move the
shift lever out of PARK (refer to “Brake/Transmission
Shift Interlock System” in this section). To drive, move
the shift lever from PARK or NEUTRAL to the DRIVE
position. Pull the shift lever toward you when shifting
into REVERSE or PARK, or when shifting out of PARK
(column shift only).
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics areself-calibrating; therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake pedal when
shifting between these gears.
The transmission shift lever has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual down-
shifts can be made using the Electronic Range Select
(ERS) shift control (refer to “Electronic Range Select (ERS)
Operation” in this section). Pressing the ERS (-/+)
switches (column shift) or moving the shift lever to the
left or right (-/+) (console shift) while in the DRIVE
position will select the highest available transmission
gear, and will display that gear in the instrument cluster
as 1, 2, 3, etc.
406 STARTING AND OPERATING

DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first and sec-
ond gears, direct third gear and overdrive fourth and
fifth gears. The DRIVE position provides optimum driv-
ing characteristics under all normal operating conditions.
To access all six available gears, you must use the
Electronic Range Select (ERS) shift control, described
below.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the Electronic Range
Select (ERS) shift control (refer to “Electronic Range
Select (ERS) Operation)” in this section) to select a lower
gear range. Under these conditions, using a lower gearrange will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operat-
ing limits, the powertrain controller will modify the
transmission shift schedule and expand the range of
torque converter clutch engagement. This is done to
prevent transmission damage due to overheating.
If the transmission becomes extremely hot or is in danger
of overheating, the “Transmission Temperature Warning
Light” may illuminate and the transmission may operate
differently until the transmission cools down.
NOTE:
Use caution when operating a heavily loaded
vehicle at low speeds (such as towing a trailer up a steep
grade, or in stop-and-go traffic) during hot weather. In
these conditions, torque converter slip can impose a
significant additional heat load on the cooling system.
