Blue Indicator Lights
High Beam Indicator Light
This indicator light will illuminate to
indicate that the high beam head -
lights are on. With the low beams acti -
vated, push the multifunction lever
forward (toward the front of the vehicle) to turn
on the high beams. Pull the multifunction lever
rearward (toward the rear of the vehicle) to turn
off the high beams. If the high beams are off,
pull the lever toward you for a temporary high
beam on, "flash to pass" scenario.
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 emis -
sions, 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 govern -
ment 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)
Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (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 diag
-
nosis and service of your vehicle and emissions
system.
For further information, refer to “Cybersecurity”
in “Multimedia”.
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 acci -
dent involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

222STARTING AND OPERATING
2WD Or 4WD HIGH To 4WD LOW
NOTE:
When shifting into or out of 4WD LOW some
gear noise may be heard. This noise is normal
and is not detrimental to the vehicle or occu -
pants.
Shifting can be performed with the vehicle
rolling 2 to 3 mph (3 to 5 km/h) or completely
stopped. You can use either of the following
procedures:
Preferred Procedure

1. With the engine running, slow the vehicle to 2 to 3 mph (3 to 5 km/h).

2. Shift the transmission into NEUTRAL.
3. While still rolling, push the desired position on the transfer case control switch.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear. Alternate Procedure

1. Bring the vehicle to a complete stop.

2. With the ignition switch in the ON position
and the engine running, shift the transmis -
sion into NEUTRAL.
3. Push the desired position on the transfer case control switch.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear.
NOTE:
If Steps 1 or 2 of either the Preferred or Alter -
nate Procedure are not satisfied prior to
attempting the shift, then the desired posi -
tion indicator light will flash continuously
while the original position indicator light is
on, until all requirements have been met.
The ignition switch must be in the ON position
for a shift to take place and for the position
indicator lights to be operable. If the ignition
switch is not in the ON position, the shift will
not take place and no position indicator lights
will be on or flashing.
Electronically Shifted Transfer Case (Six
Speed Transmisson) — If Equipped
The electronic shift transfer case is operated by
the 4WD Control Switch (Transfer Case Switch),
which is located on the instrument panel.

Four-Position/On-Demand Transfer Case

This electronically shifted transfer case
provides four mode positions:
Two-Wheel Drive High Range (2WD)
Four-Wheel Drive High Range (4WD HIGH)

switch must be in the ON position with the
engine either running or off. This shift cannot be
completed if the ignition switch is in the ACC
position.
NOTE:
The four-wheel drive system will not allow shifts
between 2WD/4WD HIGH if the front and/or
rear wheels are spinning (no traction). In this
situation, the selected position indicator light will flash and the original position indicator light
will remain on. At this time, reduce speed and
stop spinning the wheels to complete the shift.
2WD Or 4WD HIGH To 4WD LOW
NOTE:
When shifting into or out of 4WD LOW some
gear noise may be heard. This noise is normal
and is not detrimental to the vehicle or occu
-
pants.

STARTING AND OPERATING291
NOTE:
With electronic shift transfer case:
Steps 2 through 3 are requirements that
must be met before pushing the N (Neutral)
button, and must continue to be met until the
shift has been completed. If any of these
requirements are not met before pushing the
N (Neutral) button or are no longer met
during the shift, the N (Neutral) indicator light
will flash continuously until all requirements
are met or until the N (Neutral) button is
released.
The ignition must be in the ON/RUN mode for
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is
not in the ON/RUN mode, the shift will not
take place and no position indicator lights will
be on or flashing.
A flashing N (Neutral) position indicator light
indicates that shift requirements have not
been met.
Shifting Out Of N (Neutral)
Use the following procedure to prepare your
vehicle for normal usage:

1. Bring the vehicle to a complete stop,
leaving it connected to the tow vehicle.

2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine, and shift the transmission into NEUTRAL.
With manual shift transfer case, shift the transfer case lever to the desired posi -
tion.
With electronic shift transfer case with rotary selector switch, push and hold the
transfer case N (Neutral) button until the
N (Neutral) indicator light turns off. After
the N (Neutral) indicator light turns off,
release the N (Neutral) button. After the
N (Neutral) button has been released, the
transfer case will shift to the position indi -
cated by the selector switch.
With electronic shift transfer case with push-button selector switch, push and
hold the switch for the desired transfer
case position, until the N (Neutral) indi -
cator light turns off and the desired posi -
tion indicator light turns on.
NOTE:
When shifting out of transfer case N (Neutral),
turning the engine off is not required, but may
be helpful to avoid gear clash. With 8-speed
automatic transmission, the engine must
remain running, since turning the engine off will
shift the transmission to PARK (and the trans -
mission must be in NEUTRAL for the transfer
case to shift out of NEUTRAL).
5. Turn the engine off. Shift automatic trans- mission into PARK. On 8-speed transmis -
sions the shifter will automatically select
PARK when the engine is turned off.
6. Release the brake pedal.
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.
