•You can start out, from a stop, in first or second gear.
Tapping (+) (at a stop) will allow starting in second
gear. Starting out in second gear can be helpful in
snowy or icy conditions.
• The system will ignore attempts to upshift at too low
of a vehicle speed.
• Avoid using speed control when AutoStick is engaged.
• Transmission shifting will be more noticeable when
AutoStick is engaged.
NOTE: When the transfer case is in the 4L (Low) range,
the transmission will shift automatically (but no higher
than the displayed gear).
To disengage AutoStick mode, hold the shift lever to the
right (+) until Dis once again displayed in the instru-
ment cluster. You can shift in or out of the AutoStick
mode at any time without taking your foot off the
accelerator pedal.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.
FOUR–WHEEL DRIVE OPERATION (COMMAND-
TRAC I OR ROCK-TRAC)
WARNING!
Failure to engage a transfer case position completely
can cause transfer case damage or loss of power and
vehicle control. You could have a collision. Do not
drive the vehicle unless the transfer case is fully
engaged.

speed. This range (4L) provides additional traction and
maximum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
CAUTION!
Exceeding 25 mph (40 km/h) while the transfer case is
engaged in 4L may result in an engine overspeed
condition and engine damage.
The “4WD Indicator Light” (located in the instrument
cluster) will illuminate when the transfer case is shifted
into the 4L position.
NOTE: When in 4L, the “ESC Off Indicator Light” will
display in the instrument cluster.
Shifting Procedure
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with the
vehicle stopped or in motion. With the vehicle in motion,
the transfer case will engage/disengage faster if you
momentarily release the accelerator pedal after complet-
ing the shift. Apply a constant force when shifting the
transfer case lever.
4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission into NEUTRAL (N), or press
the clutch pedal on a manual transmission. While the
vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the
transfer case lever firmly to the desired position. Do not
pause with the transfer case in N (Neutral). Once the shift
is completed, place the automatic transmission into
DRIVE or release the clutch pedal on a manual transmis-
sion.

maneuver, the ESC and ERM systems will not engage
to assist in maintaining stability. The ESC Full Off
mode is intended for off-road use only.
4L Range (4WD Models)
ESC Full Off
This is the normal operating mode for ESC in 4L range.
Whenever the vehicle is started in 4L range, or the
transfer case (if equipped) is shifted from 4H range or
NEUTRAL to 4L range, the ESC system will be in this
mode. In 4L range, ESC and TCS, except for the Brake
Limited Differential (BLD) feature described in the TCS
section, are turned off until the vehicle reaches an ap-
proximate speed of 40 mph (64 km/h). For speeds at or
exceeding approximately 40 mph (64 km/h) the ESC goes
into ESC Partial Off When the vehicle speed drops
below 35 mph (56 km/h), the ESC system goes back to ESC Full Off. The ESC is in
ESC Full Offat low vehicle
speeds in 4L range so that it will not interfere with
off-road driving, but the ESC function returns to provide
the stability feature at speeds above 40 mph (64 km/h).
The “ESC OFF Indicator Light” will always be illumi-
nated in 4L range when ESC is in ESC Full OfforESC
Partial Off.
NOTE: The “ESC OFF” message will display and an
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.
WARNING!
With the ESC in ESC Full Offmode, the engine

Monitoring Telltale Light” to illuminate or the chime to
sound while stowed in the spare location.The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the EVIC, and an
audible chime will be activated when one or more of the
four active road tire pressures are low. Should this occur,
you should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value. The system will automatically update and the
“Tire Pressure Monitoring Telltale Light” will extinguish
once the updated tire pressures have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information. The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and will remain on solid when
a system fault is detected. The system fault will also
sound a chime. If the ignition key is cycled, this sequence
will repeat, providing the system fault still exists. The
“Tire Pressure Monitoring Telltale Light” will turn off
when the fault condition no longer exists. A system fault
can occur by any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.

3. Lots of snow or ice around the wheels or wheelhousings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
Vehicles not equipped with EVIC will inform the driver
which tire(s) are low but not provide actual tire pressure.
The low tire ISO telltale will illuminate along with
“LoTIrE” message displayed in the ODO and then it will
scroll to which tire location is lower than the Placard Value.
Tire location will be displayed as follows:
LF = LeftFront
rF = right Front
Lr = Leftrear
rr = right rear NOTE:
•
If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS) when swapped
with a low pressure road tire. In the event that the
matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to
be ON, and a chime to sound. Driving the vehicle for
up to 20 minutes above 15 mph (24 km/h) will turn
OFF the “Tire Pressure Monitoring Telltale Light” as
long as none of the road tires are below the low
pressure warning threshold.
• If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a tire pressure monitoring sensor in the spare tire.
The TPMS will not be able to monitor the tire pressure.
528 STARTING AND OPERATING
Page 531 of 705

If you install the spare tire in place of a road tire that
has a pressure below the low-pressure warning limit,
upon the next ignition key cycle, a chime will sound
and the “Tire Pressure Monitoring Telltale Light” will
turn ON. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds
and then remain on solid. For each subsequent ignition
key cycle, a chime will sound and the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. Once you repair or
replace the original road tire, and reinstall it on the
vehicle in place of the spare tire, the TPMS will update
automatically and the “Tire Pressure Monitoring Tell-
tale Light” will turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any of the
four active road tires. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.Premium System — If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.

NOTE:It is particularly important, for you to regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC), and a graphic displaying tire pressures
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel, if the vehicle is equipped with a matching full-size
spare wheel and tire assembly. The matching full-size
spare tire can be used in place of any of the four road
tires.Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated, when one or more of the
four active road tire pressures are low. In addition, the
EVIC will display a “LOW TIRE” message for a mini-
mum of five seconds. An “Inflate to XX” message and a
graphic display of the pressure value(s) with the low
tire(s) “flashing” will also be displayed. Refer to “Elec-
tronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.
NOTE: Your system can be set to display pressure units
in PSI, kPa, or BAR.

Page 533 of 705

Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is “flashing” on the graphic
display to the vehicle’s recommended cold tire pressure
inflation value shown in the “Inflate to XX” message. The
system will automatically update, the graphic display ofthe pressure value(s) will stop “flashing,” and the Tire
Pressure Monitoring Telltale Light will extinguish once
the updated tire pressure(s) have been received.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (24 km/h) to receive this information.
SERVICE TPM SYSTEM Warning
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with “- -“Tire Pressure Monitor Display
