Engine Check/Malfunction Indicator
Warning Light (MIL)
The MIL is a part of an Onboard Diagnostic
System called OBD II that monitors engine and
automatic transmission control systems. This
warning light will illuminate when the ignition is
in the ON/RUN position before engine start. If the bulb
does not come on when turning the ignition switch from
OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap,
poor quality fuel, etc., may illuminate the light after engine
start. The vehicle should be serviced if the light stays on
through several typical driving styles. In most situations,
the vehicle will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.
WARNING!
A malfunctioning catalytic converter can reach higher
temperatures than in normal operating conditions. This
can cause a fire if you drive slowly or park over
flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious
injury to the driver, occupants or others.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see an authorized dealer for service as soon as possible.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have OBD II and a connection
port to allow access to information related to the
performance of your emissions controls. Authorized
service technicians may need to access this information to
assist with the diagnosis and service of your vehicle and
emissions system
Úpage 191.
CAUTION!
 Prolonged driving with the MIL on could cause further
damage to the emission control system. It could also
affect fuel economy and driveability. The vehicle
must be serviced before any emissions tests can be
performed.
 If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
 If unauthorized equipment is connected to the OBD II
connection port, such as a driver-behavior tracking
device, it may:
 Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
 Access, or allow others to access, information
stored in your vehicle systems, including
personal information.

STARTING AND OPERATING127
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.
When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added
precaution, turn the front wheels toward the curb on a
downhill grade and away from the curb on an uphill grade.
NOTE:On four-wheel drive vehicles be sure that the transfer case
is in a drive position.
When exiting the vehicle, always:
Apply the parking brake.
 Shift the transmission into PARK.
 Turn the engine off.
 Remove the key fob from the vehicle. The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:

Look at the transmission gear position display and
verify that it indicates the PARK position (P), and is not
blinking.
 With the brake pedal released, verify that the gear
selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must exit the
vehicle. DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), select TOW/HAUL
mode or use the Electronic Range Select (ERS) shift
control to select a lower gear range
Úpage 128. 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
depending on engine and transmission temperature as
well as vehicle speed. Normal operation will resume once
the transmission temperature has risen to a suitable level.
CAUTION!
 DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range, as this can
damage the drivetrain.
 Before moving the transmission gear selector out of
PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition
to coast down a hill. These are unsafe practices that
limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.

STARTING AND OPERATING129
AutoStick — If Equipped
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control of
the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This feature can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving, trailer
towing, and many other situations.

Paddle Shifters

Operation
In AutoStick mode, you can use the gear selector (in the
SPORT position), or the paddle shifters, to manually shift
the transmission. To activate AutoStick mode, move the
gear selector into the SPORT (S) position (beside the
DRIVE position), or tap one of the paddle shifters on the
steering wheel. Tapping the “-” shift paddle to enter
AutoStick mode will downshift the transmission to the next
lower gear, while tapping “+” to enter AutoStick mode will
retain the current gear. The current transmission gear will
be displayed in the instrument cluster.
AutoStick mode has the following operational benefits:
The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
 The transmission will automatically downshift to FIRST
gear when coming to a stop. After a stop, the driver
should manually upshift “+” the transmission as the
vehicle is accelerated.
 You can start out, from a stop, in FIRST or SECOND gear
(or THIRD gear, in 4WD LOW). Tapping “+” (at a stop)
will allow starting in SECOND gear. Starting out in
SECOND or THIRD gear can be helpful in snowy or icy
conditions.
 If a requested downshift would cause the engine to
overspeed, that shift will not occur. 
The system will ignore attempts to upshift at too low of
a vehicle speed.
 Holding the “-” paddle pressed, or holding the gear
selector in the “-” position, will downshift the transmis -
sion to the lowest gear possible at the current speed.
 Transmission shifting will be more noticeable when
AutoStick is enabled.
 The system may revert to automatic shift mode if a
fault or overheat condition is detected.
NOTE:When Selec-Speed or Hill Descent Control is enabled,
AutoStick is not active.
To disengage AutoStick, return the gear selector to the
DRIVE position, or press and hold the “+” paddle shifter
(and the gear selector is already in DRIVE) until "D" is once
again indicated in the instrument cluster. You can shift in
or out of AutoStick at any time without taking your foot off
the accelerator pedal.
1 — “-” Paddle
2 — “+” Paddle
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

130STARTING AND OPERATING
When to Use TOW/HAUL Mode
Select TOW/HAUL mode when driving in conditions such
as: driving in hilly areas, towing a trailer, carrying a heavy
load, etc. This mode will improve performance and reduce
the potential for transmission overheating or failure due to
excessive shifting.

TOW/HAUL Switch

The TOW/HAUL Indicator Light will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default
at engine start-up. If TOW/HAUL mode is desired, the
switch must be pushed each time the engine is started.

F EQUIPPED
This is an electronic shift transfer case and is operated by
the 4WD Control Switch (Transfer Case Switch), located on
the instrument panel.

Four-Position/On-Demand Transfer Case

This electronically shifted transfer case provides four
positions:
 Two-Wheel Drive High Range (2WD) — This range is for
normal street and highway driving on dry hard surfaced
roads. Driving the vehicle in 2WD will have greater fuel
economy benefits as the front axle is not engaged in
2WD.
 Four-Wheel Drive High Range (4WD HIGH) — This range
provides torque to the front driveshaft (engages
four-wheel drive) which allows front and rear wheels to
spin at the same speed. This provides additional
traction for loose or slippery road surfaces only.
WARNING!
Do not use the TOW/HAUL feature when driving in icy or
slippery conditions. The increased engine braking can
cause the rear wheels to slide, and the vehicle to swing
around with the possible loss of vehicle control, which
may cause an accident possibly resulting in personal
injury or death.

23_DT_OM_EN_USC_t.book Page 130

STARTING AND OPERATING131
Four-Wheel Drive Low Range (4WD LOW) — This range
provides low speed four-wheel drive. It maximizes
torque (increased torque over 4WD HIGH) to the front
driveshaft; allowing front and rear wheels to rotate at
the same speed. This range provides additional trac -
tion and maximum pulling power for loose or slippery
road surfaces only. Do not exceed 25 mph (40 km/h)
in this range.
 N (Neutral) — This range disengages both the front and
rear driveshafts from the powertrain. To be used for flat
towing behind another vehicle
Úpage 187.
NOTE:
The 4WD HIGH and 4WD LOW positions are designed
for loose, slippery road surfaces only. Driving in the
4WD HIGH and 4WD LOW positions on dry, hard
surfaced roads may cause increased tire wear and
damage to the driveline components.
 The transfer case N (Neutral) button is located in the
center of the 4WD Control Switch and is pushed by
using a ballpoint pen or similar object. The transfer
case N (Neutral) position is to be used for recreational
towing only
Úpage 187.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD HIGH
and 4WD LOW) are located in the instrument cluster and
indicate the current and desired transfer case selection.
When you select a different transfer case position, the
indicator lights will do the following:

1. The current position indicator light will turn off.

2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and remain on. If the transfer case does not shift into the desired position,
one or more of the following events may occur:

1. The indicator light for the current position will
remain on.

2. The newly selected position indicator light will continue to flash.
3. If the transfer case will not shift, a message will
appear on the cluster stating the 4WD shift has
canceled.NOTE:Before retrying a selection, make certain that all the
necessary requirements for selecting a new transfer case
position have been met. To retry the selection, push the
current position, wait five seconds, and retry selection.
The SERV 4WD Warning Light monitors the electronic shift
four-wheel drive system. If this light remains on after
engine start-up or illuminates during driving, it means that
the four-wheel drive system is not functioning properly and
that service is required.WARNING!
 You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
N (Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear drive shaft from
the powertrain, and will allow the vehicle to roll, even
if the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
 The transmission may not engage PARK if the vehicle
is moving. Always bring the vehicle to a complete
stop before shifting to PARK, and verify that the
transmission gear position indicator solidly indicates
PARK (P) without blinking. Ensure that the vehicle is
completely stopped, and the PARK position is prop -
erly indicated, before exiting the vehicle.
WARNING!
Always engage the parking brake when powering down
the vehicle if the SERV 4WD Warning Light is
illuminated. Not engaging the parking brake may allow
the vehicle to roll which may cause personal injury or
death.

23_DT_OM_EN_USC_t.book Page 131

132STARTING AND OPERATING
NOTE:Do not attempt to make a shift while only the front or rear
wheels are spinning. This could cause damage to driveline
components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD or
4WD HIGH positions at a given road speed. Take care not
to overspeed the engine and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type and circumference on each wheel.
Any difference in tire size can cause damage to the
drivetrain.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
Shifting Procedure
If any of the requirements to select a new transfer case
position have not been met, then the transfer case will
not shift. The position indicator light for the previous
position will remain on and the newly selected position
indicator light will continue to flash until all the require -
ments for the selected position have been met.
 If all the requirements to select a new transfer case
position have been met, then the current position indi -
cator light will turn off and the selected position indi -
cator light will flash until the transfer case completes
the shift. When the shift is complete, the position indi -
cator light for the selected position will stop flashing
