Tow/Haul Mode Selector Switch
(Automatic Transmission)
Your vehicle is equipped with a tow/haul mode. The
selector switch is located on the end of the column shift
lever. You can use this feature to assist when towing or
hauling a heavy load. See ªTow/Haul Modeº in the
Index for more information.
Manual Transmission Operation
5-Speed (VORTEC 6000 V8 Engine)
Here's how to operate
your transmission.
FIRST (1) is intended only for heavy loads or trailer
towing and is not recommended for normal driving.
During the first 500 miles (805 km) of vehicle use, start
your vehicle moving in FIRST (1). This allows clutch
components to break
-in properly.

2-29
FIRST (1): Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal as
you press the accelerator pedal. Shift into FIRST (1)
only when the vehicle is below 5 mph (8 km/h). If you
try to shift down into FIRST (1) at excessive vehicle
speeds, the shift lever will not move into FIRST (1)
until vehicle speed is reduced.
SECOND (2): Press the clutch pedal and shift into
SECOND (2). Then, slowly let up on the clutch pedal
as you press the accelerator pedal.
You can shift into SECOND (2) when you're going less
than 20 mph (32 km/h). If you've come to a complete
stop and it's hard to shift into SECOND (2), put the shift
lever into NEUTRAL and let up on the clutch. Press the
clutch pedal back down. Then shift into SECOND (2).
If you try to downshift into SECOND (2) at excessive
vehicle speeds, the shift lever will not move into the
SECOND (2) position until the vehicle speed is reduced.
THIRD (3): Press the clutch pedal and shift into
THIRD (3). Then, slowly let up on the clutch pedal
as you press the accelerator pedal.FOURTH (4) and FIFTH (5): Shift into the higher
forward gears the same way you do for THIRD (3).
Slowly let up on the clutch pedal as you press the
accelerator pedal.
To stop, let up on the accelerator pedal and press the brake
pedal. Just before the vehicle stops, press the clutch pedal
and the brake pedal, and shift to NEUTRAL.
NEUTRAL: Use this position when you start or idle
your engine.
REVERSE (R): To back up, first press down the clutch
pedal. Wait for the vehicle to stop moving and then, shift
into REVERSE (R). Let up on the clutch pedal slowly
while pressing the accelerator pedal.
NOTICE:
Shift to REVERSE (R) only after your vehicle is
stopped. Shifting to REVERSE (R) while your
vehicle is moving could damage your transmission.
Also, use REVERSE (R), along with the parking brake,
when turning off your engine and parking your vehicle.

stopped. Shifting to REVERSE (R) while your
vehicle is moving could damage your transmission.
Also, use REVERSE (R), along with the parking brake,
when turning off your engine and parking your vehicle.

2-31
6-Speed
(VORTEC 8100 V8 and DURAMAX

6600 V8 Engines)
Here's how to operate
your transmission.
This 6
-speed pattern is unique to GM manual
transmissions. The transmission always repositions the
shift lever to NEUTRAL, which is located between
FOURTH (4) and FIFTH (5) gear.
To prevent unintentional gear selections, additional force
is required to move the shift lever into REVERSE (R) or
FIRST (1). Use FIRST (1) when trailer towing, driving
with payload in the pickup box or launching on a grade.
Otherwise, start in SECOND (2) gear. Only shift into
FIRST (1) when the vehicle has stopped moving.During the first 500 miles (805 km) of vehicle use, start
the vehicle moving in FIRST (1) gear. This allows the
clutch components to wear
-in properly.
FIRST (1): With the vehicle at a stop, release the
brake, press the clutch pedal and shift into FIRST (1).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal. Only downshift into FIRST (1) when
the vehicle has come to a complete stop. If the shift
lever will not go into FIRST (1), put the lever in
NEUTRAL and let up on the clutch pedal to fully
engage the clutch. Press the clutch pedal again.
Then, shift into FIRST (1).
SECOND (2): With the vehicle at a stop, release
the brake, press the clutch pedal and shift into
SECOND (2). Then, slowly let up on the clutch pedal as
you press the accelerator pedal. With the vehicle moving,
press the clutch pedal and upshift into SECOND (2) from
FIRST (1) while applying light pressure to the right on
the shifter. Then, slowly let up on the clutch pedal as you
press the accelerator pedal. If you come to a complete stop
and the shift lever will not go into SECOND (2), put the
lever in NEUTRAL and let up on the clutch pedal to
fully engage the clutch. Press the clutch pedal again.
Then, shift into SECOND (2).

2-32
THIRD (3): Press the clutch pedal and upshift into
THIRD (3). Then, slowly let up on the clutch pedal as
you press the accelerator pedal.
FOURTH (4), FIFTH (5) and SIXTH (6): Upshift
into the higher forward gears the same way as you do
THIRD (3). Slowly let up on the clutch pedal as you
press the accelerator pedal.
NEUTRAL: Use this position when you start or idle
your engine.
REVERSE (R): To back up, press the clutch pedal.
Wait for the vehicle to stop moving and then, shift to
REVERSE (R). Let up on the clutch slowly while
pressing the accelerator pedal. Also, use REVERSE (R),
along with the parking brake, when turning off your
engine and parking your vehicle.Shift Speeds
CAUTION:
If you skip a gear when you downshift, you could
lose control of your vehicle. You could injure
yourself or others. Don't shift down more than
one gear at a time when you downshift.
Do not allow the engine rpm to overspeed and enter the
tachometer red lines. Engine overspeed occurs when
downshifting, or descending a grade, at too high a
vehicle speed. When going down steep grades, always
select a gear at least one position lower than you would
use on climbing a grade. This will allow the vehicle's
engine to provide some braking and help to slow the
vehicle as it goes down the grade. Monitor your vehicle
speed, acceleration and engine rpm while applying the
brakes as you go down the grade to ensure you have
complete control over the vehicle.

2-33
If your engine speed drops below 600 rpm, or if the
engine is not running smoothly, you should downshift to
the next lower gear. When operating on slippery
surfaces, downshift at lower than normal vehicle speeds
to prevent the tires from slipping.
In bench seat equipped vehicles, move the tallest
beverage containers to the right cupholder to provide
additional clearance for the shift lever.
For vehicles equipped with a center console, the front
cup holder pulls out and turns 180
to provide additional
clearance between tall beverage containers and the
shift lever.Shift Light
If you have a manual
transmission, you may have
a SHIFT light. This light
will show you when to shift
to the next higher gear for
best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road and traffic conditions allow.
For the best fuel economy, accelerate slowly and shift
when the light comes on.
While you accelerate, it is normal for the light to go on and
off if you quickly change the position of the accelerator.
If your vehicle has four
-wheel drive and is equipped
with a manual transmission, disregard the SHIFT light
when the transfer case is in 4
-Wheel Low.
Ignore the SHIFT light when you downshift.

2-34
Four-Wheel Drive (If Equipped)
If your vehicle has four-wheel drive, you can send
your engine's driving power to all four wheels for extra
traction. To get the most satisfaction out of four
-wheel
drive, you must be familiar with its operation. Read the
part that follows before using four
-wheel drive. See the
appropriate text for the transfer case in your vehicle.
NOTICE:
Driving in the 4-WHEEL HIGH (4HI) or
4
-WHEEL LOW (4LO) positions for a long time
on dry or wet pavement could shorten the life of
your vehicle's drivetrain.
Front Axle Locking Feature
The front axle locks and unlocks automatically when
you shift the transfer case. Some delay for the axle to
lock or unlock is normal.
Manual Transfer Case (If Equipped)
The transfer case shift lever is on the floor to the right of the
driver. Use this lever to shift into and out of four
-wheel drive.
The 4WD indicator will
light up when you shift into
four
-wheel drive and the
front axle engages.
Some delay between shifting and the indicator's lighting
is normal.

2-35
An indicator on the bezel near the lever shows you the
transfer case settings:
2
-Wheel High (2HI): This setting is used for driving
in most street and highway situations. Your front axle
is not engaged in two
-wheel drive. This setting also
provides the best fuel economy.
4
-Wheel High (4HI): Use 4HI when you need extra
traction, such as on snowy or icy roads or in most
off
-road situations. This setting also engages your front
axle to help drive your vehicle. This is the best setting to
use when plowing snow.
CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P), or if you have a manual
transmission, even if you are in gear. You or
someone else could be seriously injured. Be sure
to set the parking brake before placing the
transfer case in NEUTRAL. See ªParking Brakeº
in the Index.
NEUTRAL (N): Shift to this setting only when your
vehicle needs to be towed. The ignition switch must be
in RUN in order to shift the lever into NEUTRAL (N).
See ªRecreational Vehicle Towingº or ªTowing your
Vehicleº in the Index.
4
-Wheel Low (4L0): This setting also engages your
front axle and delivers extra torque. You may never need
4LO. It sends maximum power to all four wheels. You
might choose 4LO if you are driving off
-road in deep
sand, deep mud, deep snow and climbing or descending
steep hills.

2-36
You can shift from 2-Wheel High (2HI) to
4
-Wheel High (4HI) or from 4-Wheel High (4HI) to
2
-Wheel High (2HI) while the vehicle is moving. Your
front axle will engage faster if you take your foot off of
the accelerator for a couple of seconds after you shift.
In extremely cold weather, it may be necessary to stop
or slow the vehicle to shift into 4
-Wheel High (4HI).
To shift into or out of 4
-Wheel Low (4LO)
or NEUTRAL (N):
1. Slow the vehicle to a roll, about 1 to 3 mph
(2 to 5 km/h) and shift an automatic transmission
into NEUTRAL (N), or with a manual transmission,
press the clutch pedal.
2. Shift the transfer case shift lever in
one continuous motion.
Don't pause in NEUTRAL (N) as you shift the transfer
case into 4
-Wheel Low (4LO), or your gears could clash.
Remember that driving in 4
-Wheel High (4HI) or
4
-Wheel Low (4LO) may reduce fuel economy. Also,
driving in four
-wheel drive on dry pavement could
cause your tires to wear faster and make your transfer
case harder to shift and run noisier.
Automatic Transfer Case (If Equipped)
The transfer case switches
are located to the left of the
instrument panel cluster.
Use these switches to shift into and out of four
-wheel drive.

2-37
You can choose among four driving settings:
2HI: This setting is used for driving in most street and
highway situations. Your front axle is not engaged in
two
-wheel drive. This setting also provides the best
fuel economy.
AUTO 4WD: This setting is ideal for use when road
conditions are variable. When driving your vehicle in
AUTO 4WD, the front axle is engaged, but the vehicle's
power is sent to the rear wheels. When the vehicle
senses a loss of traction, the system will automatically
engage four
-wheel drive. Driving in this mode results in
slightly lower fuel economy than 2HI.4HI: Use 4HI when you need extra traction, such as on
snowy or icy roads or in most off
-road situations. This
setting also engages your front axle to help drive your
vehicle. This is the best setting to use when plowing snow.
4LO: This setting also engages your front axle and
delivers extra torque. You may never need 4LO. It sends
maximum power to all four wheels. You might choose
4LO if you are driving off
-road in deep sand, deep mud,
deep snow and climbing or descending steep hills.
CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P). You or someone else could be
seriously injured. Be sure to set the parking
brake before placing the transfer case in
NEUTRAL. See ªParking Brakeº in the Index.
NEUTRAL: Shift the vehicle's transfer case to
NEUTRAL only when towing your vehicle. See
ªRecreational Vehicle Towingº or ªTowing Your
Vehicleº in the Index for more information.
