2006Chevrolet TrailBlazer/TrailBlazer EXT Owner ManualM

Q:If I am a good driver, and I never drive far from
home, why should I wear safety belts?
A:You may be an excellent driver, but if you are in an
accident — even one that is not your fault — you
and your passengers can be hurt. Being a good
driver does not protect you from things beyond your
control, such as bad drivers.
Most accidents occur within 25 miles (40 km)
of home. And the greatest number of serious
injuries and deaths occur at speeds of less than
40 mph (65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-33
orInfants and Young Children on page 1-36. Follow
those rules for everyone’s protection.
First, you will want to know which restraint systems your
vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
1-20

Right Front Passenger Position
To learn how to wear the right front passenger’s safety
belt properly, seeDriver Position on page 1-20.
The right front passenger’s safety belt works the same
way as the driver’s safety belt — except for one thing.
If you ever pull the shoulder portion of the belt out all the
way, you will engage the child restraint locking feature.
If this happens, just let the belt go back all the way and
start again.
Rear Seat Passengers
It is very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in
the rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who are not safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Lap-Shoulder Belt
All rear seat positions have lap-shoulder belts. Here is
how to wear one properly.
1. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
1-27

{CAUTION:
Children can be seriously injured or strangled
if a shoulder belt is wrapped around their neck
and the safety belt continues to tighten.
Secure any unused safety belts behind the
child restraint so children cannot reach them.
Pull the shoulder belt all the way out of the
retractor to set the lock, if your vehicle has
one, after the child restraint has been installed.
Be sure to follow the instructions of the child
restraint manufacturer.
Notice:Contact between the child restraint or the
LATCH attachment parts and the vehicle’s safety
belt assembly may cause damage to these parts.
Make sure when securing unused safety belts
behind the child restraint that there is no contact
between the child restraint or the LATCH attachment
parts and the vehicle’s safety belt assembly.
Folding an empty rear seat with the safety belts
secured, may cause damage to the safety belt or the
seat. When removing the child restraint, always
remember to return the safety belts to their normal
position before folding the rear seat.1. Attach and tighten the lower attachments to the
lower anchors. If the child restraint does not have
lower attachments or the desired seating position
does not have lower anchors, secure the child
restraint with the top tether and the safety belts.
Refer to your child restraint manufacturer
instructions and the instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. For ve-passenger vehicles, pull the strap at
the center of the seat where the seat
cushion meets the seatback. This will allow
you to fold the seat cushion up and out
of the way. Lift the ap to expose the anchors
and then lower the seat cushion. SeeRear
Seat Operation on page 1-10for additional
information. Be sure the cushion is locked
into place.
1.3. Put the child restraint on the seat.
1.4. Attach and tighten the lower attachments on
the child restraint to the lower anchors.

4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.5. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt and feed the shoulder
belt back into the retractor. If you are using a
forward-facing child restraint, you may nd it helpful
to use your knee to push down on the child
restraint as you tighten the belt.
1-52

2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
4. Buckle the belt. Make sure the release button is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.5. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.
1-56

6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the
lap portion of the belt and feed the shoulder
belt back into the retractor. If you are using a
forward-facing child restraint, you may nd it helpful
to use your knee to push down on the child
restraint as you tighten the belt. You should not be
able to pull more of the belt from the retractor
once the lock has been set.7. Push and pull the child restraint in different
directions to be sure it is secure.
8. If the airbag is off, the off indicator in the rearview
mirror will be lit and stay lit when the key is turned
to RUN or START.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to make
sure that the vehicle’s seatback is not pressing the child
restraint into the seat cushion. If this happens, slightly
recline the vehicle’s seatback and adjust the seat
cushion if possible. Also make sure the child restraint is
not trapped under the vehicle head restraint. If this
happens, adjust the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
You can use the remote keyless entry transmitter.
You can use your key to unlock your door from the
outside.
You can lock or unlock the door from the inside by sliding
the manual lever forward or rearward. When the door is
unlocked, you can see a red area on the lever.
The manual lever on each door works only that
door’s lock.
