Downshifting
Moving from a high gear down to a lower gear
is recommended to preserve brakes when
driving down steep hills. In addition, down-
shifting at the right time provides better ac-
celeration when you desire to resume speed.
Downshift progressively. Do not skip gears to
avoid overspeeding the engine and clutch.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip, and the ve-
hicle could skid.
CAUTION!
• Skipping gears and downshifting intolower gears at higher vehicle speeds can
damage the engine and clutch systems,
CAUTION!
Any attempt to shift into lower gear with
clutch pedal depressed may result dam-
age to the clutch system. Shifting into
lower gear and releasing the clutch may
result in engine damage.
• When descending a hill, be very careful
to downshift one gear at a time to pre-
vent overspeeding the engine which can
cause engine damage, and/or clutch
damage, even if the clutch pedal is
pressed. If transfer case is in low range
the vehicle speeds to cause engine and
clutch damage are significantly lower.
• Failure to follow the maximum recom-
mended downshifting speeds may cause
the engine damage and/or damage the
clutch, even if the clutch pedal is
pressed.
CAUTION!
• Descending a hill in low range withclutch pedal depressed could result in
clutch damage.
Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the maximum recom-
mended downshifting speeds may cause
the engine to overspeed and/or damage the
clutch disc, even if the clutch pedal is
pressed.

some vehicle and driveline combinations uti-
lize 9th gear only in very specific driving
situations and conditions.
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 be-
tween these gears.
The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE, and
Electronic Range Select (ERS) shift posi-
tions. Manual downshifts can be made using
the ERS shift control. Moving the gear selec-
tor into the ERS (-/+) position (beside the
DRIVE position) activates ERS mode, dis-
plays the current gear in the instrument clus-
ter, and prevents automatic upshifts beyond
this gear. In ERS mode, toggling the gear
selector forward (-) or rearward (+) will
change the highest available gear.
Refer to “Electronic Range Select (ERS) Op-
eration” in the Owner’s Manual.NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward) it is probably in the
ERS (+/-) position (beside the DRIVE posi-
tion). In ERS mode, the transmission gear
limit (1, 2, 3, etc.) is displayed in the instru-
ment cluster. Move the gear selector to the
right (into the DRIVE [D] position) for access
to PARK, REVERSE, and NEUTRAL.FOUR-WHEEL DRIVE
OPERATION
1-Speed Four-Wheel Drive (4X4) —
If Equipped
This feature provides on-demand four-wheel
drive (4X4). The system is automatic with no
driver inputs or additional driving skills re-
quired. Under normal driving conditions, the
front wheels provide most of the traction. If
the front wheels begin to lose traction, power
is shifted automatically to the rear wheels.
The greater the front wheel traction loss, the
greater the power transfer to the rear wheels.
Gear Selector
STARTING AND OPERATING
130

Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
pre-emptive effort to improve vehicle launch
and performance characteristics.
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.
Unequal tire size may cause failure of the
power transfer unit.
2-Speed Four-Wheel Drive (4x4) —
If Equipped
The Four-Wheel Drive is fully automatic in the
normal driving mode. The Selec-Terrain but-
tons provide three selectable mode positions:
• 4WD LOW
• REAR LOCK (If Equipped)
• NEUTRAL
1-Speed 4X4 Switch
2-Speed 4x4 Switch
2-Speed 4x4 Switch (with Rear Lock)
131

When additional traction is required, the
4WD LOW range position can be used to
provide an additional gear reduction which
allows for increased torque to be delivered to
both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces
only. Driving in 4WD LOW on dry, hard-
surfaced roads may cause increased tire wear
and damage to driveline components.
When operating your vehicle in 4WD LOW,
the engine speed is approximately three
times that of the normal driving mode 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
will adversely affect shifting and cause dam-
age to the driveline components.
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.Shift Positions
For additional information on the appropriate
use of each 4WD system mode position, see
the information below:
NEUTRAL
This range disengages the driveline from the
powertrain.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
power transfer unit in the NEUTRAL (N)
position without first fully engaging the
parking brake. The NEUTRAL (N) position
disengages both the front and rear drive-
shafts from the powertrain and will allow
the vehicle to roll, even if the automatic
transmission is in PARK (or manual trans-
mission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive.
It provides an additional gear reduction
which allows for increased torque to be deliv-
ered to both the front and rear wheels while
providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed
25 mph (40 km/h).
NOTE:
Refer to “Selec-Terrain — If Equipped” for
further information on the various positions
and their intended usages.
Shifting Procedures
Shifting Into 4X4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition in the ON mode and the
engine running, shift the transmission into
NEUTRAL, and push the “4WD LOW” button
once. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and
remain on solid when the shift is complete.
STARTING AND OPERATING
132

2. The ignition in the ON mode and theengine running.
3. To disengage Rear E-Locker, push the REAR LOCK button once.
NOTE:
• It may also be necessary to drive slowly steering back and forth to complete en-
gagement and disengagement of the
E-Locker.
• When engaging Rear E-Locker, the indica- tor lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain on.
• When disengaging Rear E-Locker, the indi- cator lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain off.
• Shifting into or out of Rear E-Locker is possible with the vehicle completely
stopped; however, difficulty may occur due
to the mating clutch teeth not being prop-
erly aligned. Several attempts may be re-
quired for clutch teeth alignment and shift
completion to occur. The preferred method is for the vehicle to be rolling, below
15 MPH (24 km/h), while including right
and left steering maneuvers to allow for the
clutch teeth to align.
• The Rear E-Locker System must be disen- gaged prior to taking the vehicle out of 4WD
LOW range. If 4WD LOW shift conditions/
interlocks are not met, a message will flash
from the instrument cluster display with
instructions on how to complete the re-
quested shift.
SELEC-TERRAIN
Description
Selec-Terrain combines the capabilities of
the vehicle control systems, along with driver
input, to provide the best performance for all
terrains.
Rotate the Selec-Terrain knob to select the
desired mode. Selec-Terrain offers the following modes:
•
Auto — Fully automatic full time four-wheel
drive operation can be used on and off road.
Balances traction with seamless steering
feel to provide improved handling and ac-
celeration over two-wheel drive vehicles.
• Snow — Tuning set for additional stability
in inclement weather. Use on and off road
on loose traction surfaces such as snow.
When in SNOW mode (depending on cer-
Selec-Terrain Switch
135

tain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage.
• Sport — This mode alters the transmis-
sion's automatic shift schedule for sportier
driving. Upshift speeds are increased to
make full use of available engine power.
NOTE:
SPORT mode is not available when 4WD LOW
is selected.
• Sand/Mud — Off-road calibration for use on
low traction surfaces such as mud, sand, or
wet grass. Driveline is maximized for trac-
tion. Some binding may be felt on less
forgiving surfaces. The electronic brake
controls are set to limit traction control
management of throttle and wheel spin.
• Rock — Off-road calibration only available
in 4WD LOW range. Traction based tuning
with improved steer-ability for use on high
traction off-road surfaces. Use for low
speed obstacles such as large rocks, deep
ruts, etc. NOTE:
• Rock mode is only available on the vehicles
equipped with the Off-Road package.
• Activate the Hill Descent Control or Selec Speed Control for steep downhill control.
See “Electronic Brake Control System” in
“Safety” for further information.
STOP/START SYSTEM —
IF EQUIPPED
The Stop/Start function was developed to
reduce fuel consumption. The system will
stop the engine automatically during a ve-
hicle stop if the required conditions are met.
Releasing the brake pedal or pressing the
accelerator pedal will automatically restart
the engine.
This vehicle has been upgraded with a Heavy
Duty Battery, Starter, as well as other engine
parts, to handle the Additional engine starts.
Automatic Mode
The Stop/Start feature is enabled after every
normal customer engine start. At that time,
the system will go into STOP/START READY
and if all other conditions are met, can go
into a STOP/START AUTOSTOP ACTIVE “Au-
tostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
• The system must be in STOP/STARTREADY state. A STOP/START READY mes-
sage will be displayed in the instrument
cluster display within the Stop/Start sec-
tion. Refer to “Warning Lights And Mes-
sages” in “Getting To Know Your Instru-
ment Panel” in your Owner’s Manual.
• The vehicle must be completely stopped.
• The gear selector must be in a forward gear and the brake pedal depressed.
The engine will shut down, the tachometer
will move to the zero position and the Stop/
Start telltale will illuminate indicating you
are in Autostop. Customer settings will be
maintained upon return to an engine running
condition.
