2004 Chevrolet Colorado Owner ManualM

Power Seats
If your vehicle has this feature, there will be a control on
the outboard side of the front seat(s).Horizontal Control:Raise or lower the front of the seat
by raising or lowering the forward edge of the control.
Raise or lower the rear of the seat by raising or lowering
the rear edge of the control.
Move the seat forward or rearward by moving the whole
control toward the front or the rear of the vehicle.
Moving the whole control up or down raises or lowers
the whole seat.
Vertical Control:This control reclines the seatbacks.
SeeReclining Seatbacks on page 1-6for more
information.
1-4

Reclining Seatbacks
Your vehicle may have reclining seatbacks.
To manually recline your seatback, lift the lever on the
outboard side of the seat.
Release the lever to lock the seatback where you want
it. Pull up on the lever and without pushing on the
seatback, the seat will go to an upright position.
If you have power seats, you can use the vertical power
seat control to recline the seatback. Move the reclining
front seatback forward or rearward by moving the control
toward the front or rear of the vehicle.But don’t have a seatback reclined if your vehicle is
moving.

{CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can not properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:If the child is sitting in a rear outside seat position,
move the child toward the center of the vehicle. See
Rear Safety Belt Comfort Guides for Children and
Small Adults on page 1-29. If the child is sitting in the
center rear seat of a crew cab, move the child toward
the safety belt buckle. In either case be sure that the
shoulder belt still is on the child’s shoulder, so that in
a crash the child’s upper body would have the
restraint that belts provide.

Child Restraint Systems
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuous at
surface. Make sure that the infant’s head rests toward
the center of the vehicle.A rear-facing infant seat (B) provides restraint with the
seating surface against the back of the infant. The
harness system holds the infant in place and, in a crash,
acts to keep the infant positioned in the restraint.
1-38

The side impact air bags are designed to inate in
moderate to severe side crashes. A side impact air bag
will inate if the crash severity is above the system’s
designed “threshold level”. The threshold level can vary
with specic vehicle design. Side impact air bags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination would not
help the occupant. A side impact air bag will only deploy
on the side of the vehicle that is struck.
Your vehicle has seat position sensors which enable the
sensing system to monitor the position of the driver’s
seat and the right front passenger’s seat. Seat position
sensors provide information that is used to determine
if the air bags should deploy at a reduced level or at
full deployment.
In any particular crash, no one can say whether an air
bag should have inated simply because of the damage
to a vehicle or because of what the repair costs were.
For frontal air bags, ination is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal or near-frontal impacts. For side impact
air bags, ination is determined by the location and
severity of the impact.What Makes an Air Bag Inate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For
both frontal and side impact air bags, the sensing
system triggers a release of gas from the inator, which
inates the air bag. The inator, air bag, and related
hardware are all part of the air bag modules inside the
steering wheel and in the instrument panel in front
of the right front passenger. For vehicles with side
impact air bags, the air bag modules are located in the
ceiling of the vehicle, near the side windows.
How Does an Air Bag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant’s upper body,
stopping the occupant more gradually. But the frontal air
bags would not help you in many types of collisions,
including rollovers, rear impacts, and many side impacts,
primarily because an occupant’s motion is not toward the
air bag. Side impact air bags would not help you in many
types of collisions, including frontal or near frontal
collisions, rollovers, and rear impacts, primarily because
an occupant’s motion is not toward those air bags.

Removing the Tailgate
Follow these steps if you want to remove the tailgate:
1. Raise the
tailgate slightly.
2. Remove the retaining cables from both ends of the
tailgate by pulling upward on the clip. Then, push
forward so the larger part of the hole on the bracket
is over the bolt. Pull the end over the bolt.
3. With the tailgate halfway down, pull the tailgate
toward you at the passenger’s side and then
move the tailgate to the right to release the
passenger’s side.
Reverse the procedure to reinstall the tailgate. Make
sure it is secure.To partially lower the tailgate do the following:
1. Raise the
tailgate slightly.
2. Pull upward on each clip. Then, push forward so
the larger part of the hole on the bracket is over
the bolt. Pull the end over the bolt.
3. Slide the end tting off the bottom bolt and onto the
top bolt.
If you would like to close the tailgate, the bracket cannot
be in the partially open position and must be anchored
on the bottom bolt, using the secondary position on
the end tting. Tailgate Fully Down
Tailgate Partially Down

If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the engine
off. However, your Passlock
®system is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by Passlock
®at this time. You
may also want to check the fuse seeFuses and Circuit
Breakers on page 5-104. See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.
Starting and Operating

New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km). Do not
make full-throttle starts.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time your
new brake linings are not yet broken in. Hard
stops with new linings can mean premature
wear and earlier replacement. Follow this
breaking-in guideline every time you get new
brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-57for more information.
