In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF
position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6.
Shift into the desired gear range. If the prob-
lem is no longer detected, the transmission will
return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-
nience. Your authorized dealer has diagnos-
tic equipment to determine if the problem
could recur. If the transmission cannot be
reset, authorized dealer service is required. Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the shift lever is in the DRIVE
position. For example, if you shift the transmis-
sion into 3 (third gear), the transmission will
never shift above third gear, but will shift down
into second and first gears normally.
Use of ERS (or TOW/HAUL mode) also enables
an additional underdrive gear which is not nor-
mally used during through-gear accelerations.
This additional gear can improve vehicle perfor-
mance and cooling capability when towing a
trailer on certain grades. In ERS mode, gears 1
though 3 are underdrive gears, and ERS 4 is
direct drive. ERS 5 and 6 (Overdrive gears ) are
the same as the normal fourth and fifth gears.
You can switch between DRIVE and ERS mode at
any vehicle speed. When the shift lever is in the
DRIVE position, the transmission will operate
automatically, shifting between all available
gears. Tapping the shift lever to the left (-) 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, tap-
ping the shift lever to the left (-) or right (+) will
change the top available gear.
The instrument cluster display will show the
requested top gear limit, however the transmis-
sion will not downshift to the requested gear if
doing so would overspeed the engine. The
transmission will downshift once the vehicle
speed has slowed sufficiently.
To exit ERS mode, simply press and hold the
shift lever to the right (+) until “D” is once again
displayed in the shift lever position indicator in
the instrument cluster.
WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
press and hold the shift lever to the left (-).
The transmission will shift to the range from
which the vehicle can best be slowed down.
235

•If the vehicle has not been driven for
several days, the first few seconds of
operation after shifting the transmission
into gear may seem sluggish. This is due
to the fluid partially draining from the
torque converter into the transmission.
This condition is normal and will not
cause damage to the transmission. The
torque converter will refill within five sec-
onds after starting the engine.
FOUR-WHEEL DRIVE
OPERATION
Quadra-Trac II® Operating
Instructions/Precautions
The Quadra-Trac II® transfer case is fully auto-
matic in the normal driving 4WD AUTO mode.
The Quadra-Trac II® transfer case provides
three mode positions:
•4WD HI
• NEUTRAL
• 4WD LOW This transfer case is fully automatic in the 4WD
HI mode.
When additional traction is required, the 4WD
LOW position can be used to lock the front and
rear driveshafts together and force the front and
rear wheels to rotate at the same speed. The
4WD LOW position is intended for loose, slip-
pery road surfaces only. Driving in the 4WD
LOW position on dry, hard-surfaced roads may
cause increased tire wear and damage to drive-
line components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that
of the 4WD HI position 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 cir-
cumference on each wheel. Any difference will
adversely affect shifting and cause damage to
the transfer case.
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.
WARNING!
You or others could be injured if you leave
the vehicle unattended with the transfer case
in the NEUTRAL (N) position without first
fully engaging the parking brake. The trans-
fer case NEUTRAL (N) position disengages
both the front and rear driveshafts from the
powertrain and will allow the vehicle to move
regardless of the transmission position. The
parking brake should always be applied
when the driver is not in the vehicle.
237

Shift PositionsFor additional information on the appropriate
use of each transfer case mode position, see
the information below:
4WD AUTO
This range is used on surfaces such as ice,
snow, gravel, sand, and dry hard pavement.
NOTE:
Refer to “Selec-Terrain® – If Equipped” in
“Starting and Operating” for further infor-
mation on the various positions and their
intended usages.
NEUTRAL
This range disengages both the front and rear
driveshafts from the powertrain. It is to be used
for flat towing behind another vehicle. Refer to
“Recreational Towing” in “Starting and Operat-
ing” for further information.4WD LOW
This range is for low speed four-wheel drive. It
locks the front and rear driveshafts together and
forces the front and rear wheels to rotate at the
same speed. It provides additional traction and
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
4WD HI To 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to
5 km/h), the ignition switch in the ON position or
the engine running, shift the transmission into
NEUTRAL, and press the “4WD LOW” button
once on the transfer case switch. The “4WD
LOW” indicator light in the instrument cluster will
begin to flash and remain on solid when the shift
is complete.
NOTE:
If shift conditions/interlocks are not met, or
a transfer case motor temperature protec-
tion condition exists, a “For 4x4 Low Slow
Below 3 MPH or 5 KPH Put Trans in N Press
4 Low” message will flash from the Elec-
tronic Vehicle Information Center (EVIC). Re-
fer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information.

to provide improved handling and accelera-
tion over two-wheel drive vehicles. If
equipped with air suspension, the level will
change to NRH.
•
Sand/Mud–Off road calibration for use on low
traction surfaces such as mud, sand, or wet
grass. Driveline is maximized for traction.
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. If equipped with air suspen-
sion, the level will change to Off-Road 1.
• Rock – Off-road calibration only available in
4WD Low range. The vehicle is raised (if
equipped with Air Suspension) for improved
ground clearance. Traction based tuning with
improved steer-ability for use on high traction
off-road surfaces. Activate the Hill Descent
Control for steep downhill control. Use for low
speed obstacles such as large rocks, deep ruts, etc. If equipped with air suspension, the
vehicle level will change to Off-Road 2. If the
Selec-Terrain™ switch is in ROCK mode,
and the transfer case is switched from 4WD
Low to 4WD High, the Selec-Terrain™ sys-
tem will return to AUTO.

CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering, as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
new vehicle limited warranty.
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle. If you must drive through water, try to
determine the depth and the bottom condition
(and location of any obstacles) prior to entering.
Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in
deep water to minimize wave effects.Flowing Water
If the water is swift flowing and rising (as in
storm run-off), avoid crossing until the water
level recedes and/or the flow rate is reduced. If
you must cross flowing water avoid depths in
excess of 9 inches (23 cm). The flowing water
can erode the streambed, causing your vehicle
to sink into deeper water. Determine exit
point(s) that are downstream of your entry point
to allow for drifting.
Standing Water
Avoid driving in standing water deeper than
20 inches (51 cm), and reduce speed appropri-
ately to minimize wave effects. Maximum speed
in 20 inches (51 cm) of water is less than 5 mph
(8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil, trans-
mission oil, axle, transfer case) to assure the
fluids have not been contaminated. Contami-
nated fluid (milky, foamy in appearance) should
be flushed/changed as soon as possible to
prevent component damage.
Driving In Snow, Mud And SandIn heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting and Oper-
ating” for further information. Do not shift to a
lower gear than necessary to maintain forward
motion. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine
the conditions at the crest and/or on the
other side.
Before climbing a steep hill,
shift the trans-
mission to a lower gear and shift the transfer
case to 4WD LOW. Use first gear and 4WD
LOW for very steep hills.
