2004 Chevrolet Blazer Owner ManualM

Power Seats
If your vehicle has this feature, there will be a control on
the outboard side of your seat.
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:Move the reclining front seatback
forward or rearward by moving the control toward
the front or rear of the vehicle.
Power Lumbar
If your vehicle has this
feature, the control is
located on the outboard
side of the seat(s).
Press and hold the front of the control until you have
the desired lumbar support. To decrease lumbar
support, press and hold the rear of the control.

{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:Move the child toward the center of the vehicle, but
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. If
the child is sitting in a rear outside position of a
four-door model, seeRear Safety Belt Comfort
Guides for Children and Small Adults on page 1-28.
If the child is so small that the shoulder belt is
still very close to the child’s face or neck, you might
want to place the child in a seat that has a lap
belt, if your vehicle has one.
1-32

{CAUTION:
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child’s
hip bones are still so small that the vehicle’s
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle
up around the child’s abdomen. In a crash, the
belt would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.
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.
1-37

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. 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.
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. Air bags supplement 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 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 those air bags. Air bags should never be
regarded as anything more than a supplement to safety
belts, and then only in moderate to severe frontal or
near-frontal collisions.
What Will You See After an Air Bag
Inates?
After an air bag inates, it quickly deates, so quickly that
some people may not even realize the air bag inated.
Some components of the air bag module — the steering
wheel hub for the driver’s air bag, or the instrument panel
for the right front passenger’s bag — will be hot for a
short time. The parts of the bag that come into contact
with you may be warm, but not too hot to touch. There will
be some smoke and dust coming from the vents in the
deated air bags. Air bag ination doesn’t prevent the
driver from seeing or being able to steer the vehicle, nor
does it stop people from leaving the vehicle.

The following is a list of the available programming
options and how to set them after entering the
program mode:
All doors lock/Only the driver’s door unlocks:Press
the lock side of the power door lock switch once and
then the unlock side once. If your vehicle is not equipped
with remote keyless entry, you may not be able to
utilize this option.
All doors lock/All doors unlock:Press the lock side
of the power door lock switch once, and then the
unlock side twice.
All doors lock/None of the doors unlock:Press the
lock side of the power door lock switch once, and
then the unlock side three times.
No doors lock/None of the doors unlock:Press the
lock side of the power door lock switch twice. This turns
off the automatic lock feature. This is the factory setting.
For more information, see your dealer.The following instructions detail how to program your
door locks. Choose one of the programming options
before entering the programming mode.
To enter the program mode, do the following:
1. Begin with the ignition in OFF. Then pull the turn
signal/multifunction lever all the way toward you
and hold it while you perform the next step.
2. Turn your key to RUN and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock.
3.
You are now ready to program the automatic door
locks. Select one of the previous four programming
options and follow the instructions. You will have
30 seconds to begin programming. If you exceed the
30 second limit, the locks will automatically lock and
unlock to indicate you have left the program mode.
If this occurs, repeat the procedure beginning with
Step 1. You can exit the program mode any time
by turning the ignition to RUN. The locks will
automatically lock and unlock to indicate you are
leaving the program mode. If the lock/unlock switches
are not pressed while in the programming mode,
the auto lock/unlock setting will not be modied.

Remote Rear Glass Release
The REAR HATCH button,
located to the right of the
steering wheel on the
instrument panel, allows
you to release the
rear glass from inside
the vehicle.
If your vehicle has an automatic transmission, your shift
lever must be in PARK (P) or NEUTRAL (N) for the
release to work.
If you have a manual transmission, you must apply your
parking brake or have the ignition off before you can
open the tailgate glass.
Emergency Release for Opening
Tailgate
1. Peel back or slit the carpet to expose the access
hole in the trim panel.
2. Use a thin object to
reach through the
access holes in both
the trim panel and
the hardware cover.
3. Pry the release lever toward the passenger’s side
until the glass latch pops open.
4. Reattach the carpet securely.
2-15

Tailgate-Mounted Spare
If your vehicle has a tailgate mounted spare tire carrier,
you must move the carrier arm out of the way to
open the glass.
Here’s how to move the arm:
1. Squeeze the release handle on the carrier arm.
2. Swing the carrier arm away from the tailgate, giving
it a slight tug.
3. To close the carrier arm, latch by swinging it toward
the tailgate.
Sun Visors
To block glare, pull the visor down. It can also be
detached from the center mount and moved to the side
to block glare from that direction.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Content Theft-Deterrent
Your vehicle may be equipped with a Content
Theft-Deterrent alarm system.
With this system, the
SECURITY light will ash
as you open the door
if your ignition is off.
2-16

Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will go off
approximately ve seconds after the key is turned to RUN.
If the engine stalls and the SECURITY light ashes,
wait about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release the
key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the SECURITY message
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 5-99. See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.
Starting and Operating Your
Vehicle
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 4-60for more information.
2-18

Ignition Positions
With the key in the ignition, you can turn it to ve
different positions.
Notice:Lengthy operation of features such as the
radio in the accessory ignition position may drain
the battery and prevent your vehicle from starting.
Do not operate your vehicle in the accessory ignition
position for a long period of time.
A (ACCESSORY):This position lets you use things
like the radio and the windshield wipers when the
engine is off. Push in the key and turn it toward you.
Your steering wheel will remain locked, just as it
was before you inserted the key.{CAUTION:
On manual transmission vehicles, turning the
key to LOCK will lock the steering column and
result in a loss of ability to steer the vehicle.
This could cause a collision. If you need to
turn the engine off while the vehicle is moving,
turn the key only to OFF. Do not press the key
release button while the vehicle is moving.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
B (LOCK):This position locks your ignition, steering
wheel and transmission. It’s a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
