(Overdrive) can be deactivated
by pressing the transmission control
switch (TCS) on the end of the
gearshift lever.
The transmission control indicator
light (TCIL) (the word OFF) on the
end of the gearshift lever will
illuminate.
Drive± Not shown on the display. Activate by pressing the transmission
control switch (TCS) on the end of the gearshift lever with the gearshift
in the
position. The TCIL (the word OFF) will illuminate on the
gearshift lever. Transmission operates in gears one through three.
(Drive) provides more engine braking than(Overdrive) and is useful
when:
²driving with a heavy load.
²towing a trailer up or down steep hills.
²additional engine downhill braking is desired. If towing a trailer, refer
toDriving while you towin theTrailer towingsection.
To return to
(Overdrive) mode, press the transmission control switch
(TCS). The TCIL (the word OFF) will no longer be illuminated.
Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if driving in
overdrive is not desired.
2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
(Overdrive). Selecting 1 (Low) at

higher speeds causes the transmission to shift to a lower gear, and will
shift to 1 (Low) after vehicle decelerates to the proper speed.
Forced Downshifts
To gain acceleration in(Overdrive) or Drive (O/D OFF) when
passing another vehicle, push the accelerator to the floor. The
transmission will downshift to the appropriate gear: third, second or first
gear.
Shift strategy (4R100 automatic transmission)
To account for customer driving habits and conditions, your 4R100
automatic transmission electronically controls the shift quality by using
an adaptive learning strategy. The adaptive learning strategy is
maintained by power from the battery. When the battery is disconnected
or a new battery is installed, the transmission must relearn its adaptive
strategy. Optimal shifting will resume within a few hundred kilometers
(miles) of operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally, see your dealer or a
qualified service technician as soon as possible.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
Vehicles equipped with a manual transmission have a starter interlock
that prevents cranking the engine unless the clutch pedal is fully
depressed.
Driving

Page 118 of 256
When starting a vehicle with a manual transmission, you must:
1. Make sure the parking brake is
fully set.
2. Depress the clutch pedal fully.
3. Put the gearshift lever in N
(Neutral).
4. Turn the ignition to position 5
(START) to start the engine, let the
engine idle for a few seconds.
5. Depress the brake pedal.
6. Release the parking brake.
7. Move the gearshift lever to the
desired gear.
8. Release the brake pedal.
9. Slowly release the clutch pedal
while slowly pressing down on the
accelerator pedal.
²Do not drive with your foot resting on the clutch pedal and do not use
the clutch to hold your vehicle at a standstill while waiting on a hill.
These actions will greatly reduce clutch life.

POWER TAKE OFF (PTO) CAPABILITY (IF EQUIPPED)
Some vehicles equipped with an automatic transmission and the 6.8L or
7.3L engine are also equipped with Power Take Off (PTO) capability.
These vehicles have a special transmission case, internal components and
calibration for PTO usage. If your vehicle is equipped with a 7.3L Diesel
engine, refer to the 7.3L Diesel Supplement for information on the
auxiliary powertrain control module (APCM) and its operation.
The PTO can be used during mobile and stationary
continuous/intermittent applications.
PTO operation is disabled while the vehicle is in Overdrive (the TCIL will
not be illuminated), in N (Neutral), during engine cranking. Transmission
upshift and downshift schedules will be reduced by about 15% and will
have a firmer shift feel during PTO mobile applications.
The PTO cannot be disabled while the transmission is in Manual 3
(Overdrive position with Overdrive canceled), Manual 2, Manual 1.
Refer to the ªBody Builder's Layout Bookº for recommended electrical
installation.

Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. For more
information on driving off-road, read the ªFour Wheelingº supplement in
your owner's portfolio.
If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
Do not spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Do not reduce the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Mud and water
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.
When driving through water, determine the depth; avoid water higher
than the bottom of the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.

If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Water intrusion into the transmission may damage the
transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
Driving on hilly or sloping terrain
When driving on a hill, avoid driving crosswise or turning on steep
slopes. You could lose traction and slip sideways. Drive straight up,
straight down or avoid the hill completely. Know the conditions on the
other side of a hill before driving over the crest.
When climbing a steep hill, start in a lower gear rather than downshifting
to a lower gear from a higher gear once the ascent has started. This
reduces strain on the engine and the possibility of stalling.
When descending a steep hill, avoid sudden braking. Shift to a lower gear
when added engine braking is desired.
When speed control is on and you are driving uphill, your vehicle speed
may drop considerably, especially if you are carrying a heavy load.
If vehicle speed drops more than 16 km/h (10 mph), the speed control
will cancel automatically. Resume speed with accelerator pedal.
If speed control cancels after climbing the hill, reset speed by pressing
and holding the SET ACCEL button (to resume speeds over 50 km/h [30
mph]).
Automatic transmissions may shift frequently while driving up steep
grades. Eliminate frequent shifting by shifting out of
(Overdrive) into
a lower gear.
Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
If your vehicle is equipped with a Rear Anti-lock Brake System (RABS),
you should be careful when braking. Front brake lock-up, on any surface,
causes loss of steering control.
Driving
131
Page 132 of 256

If your vehicle is equipped with a Four Wheel Anti-lock Brake System
(ABS), apply the brakes as you normally would. In order to allow the
ABS to operate properly, keep steady pressure on the brake pedal.
When driving on snow or ice with either braking system, allow more
stopping distance and drive slower than usual. Consider using one of the
lower gears.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
²Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include passengers or
aftermarket equipment.
²Payload:Combined maximum allowable weight of cargo, passengers
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
²GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
²GVWR (Gross Vehicle Weight Rating):Maximum total weight of
the base vehicle, passengers, optional equipment and cargo. The
GVWR is specific to each vehicle and is listed on the Safety
Compliance Label on the driver's door pillar.
²GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Safety Compliance Label on the driver's door pillar.
²GCW (Gross Combined Weight):The combined weight of the
towing vehicle (including passengers and cargo) and the trailer.
²GCWR (Gross Combined Weight Rating):Maximum combined
weight of towing vehicle (including passengers and cargo) and the
trailer. The GCWR indicates the maximum loaded weight that the
vehicle is designed to tow.
²Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
