If the shoulder portion of a passenger belt with a
free‐falling latch plate is pulled out all the way, the
child restraint locking feature may be engaged.
If this happens, let the belt go back all the way and
start again.
Engaging the child restraint locking feature in the
right front seating position may affect the
passenger sensing system, if equipped. See
Passenger Sensing System
on page 2‑85for
more information.
If the belt stops before it reaches the buckle, for
lap‐shoulder belts with cinching latch plates, tilt the
latch plate and keep pulling the safety belt until it
can be buckled.
3. Push the latch plate into the buckle until it clicks. If you find that the latch plate will not go fully into
the buckle, see if you are using the correct buckle.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, see Safety Belt
Extender
on page 2‑48.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger positions.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
Squeeze the buttons (A)
on the sides of the height
adjuster and move the
height adjuster to the
desired position.
The adjuster can be moved up just by pushing up on
the shoulder belt guide.
After the adjuster is set to the desired position, try to
move it down without squeezing the buttons to make
sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for front
outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the
safety belt assembly. They can help tighten the safety
belts during the early stages of a moderate to severe
frontal, near frontal, or rear crash if the threshold
conditions for pretensioner activation are met. And,
if the vehicle has side impact airbags, safety belt
pretensioners can help tighten the safety belts in a
side crash or a rollover event.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle's safety belt
system. See Replacing Restraint System Parts After a
Crash on page 2‑94.
Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort
guides. If not, they are available through your dealer/
retailer. The guides may provide added safety belt
comfort for older children who have outgrown booster
seats and for some adults. When installed and properly
adjusted, the comfort guide positions the belt away from
the neck and head.

According to accident statistics, children and infants
are safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position. SeeWhere to Put the Restraint
on
page 2‑58for additional information.
Securing a Child Restraint Designed for the
LATCH System
{WARNING:
If a LATCH-type child restraint is not attached to
anchors, the child restraint will not be able to
protect the child correctly. In a crash, the child
could be seriously injured or killed. Install a
LATCH-type child restraint properly using the
anchors, or use the vehicle's safety belts to
secure the restraint, following the instructions that
came with the child restraint and the instructions
in this manual.
{WARNING:
Do not attach more than one child restraint to a
single anchor. Attaching more than one child
restraint to a single anchor could cause the
anchor or attachment to come loose or even
break during a crash. A child or others could be
injured. To reduce the risk of serious or fatal
injuries during a crash, attach only one child
restraint per anchor.
{WARNING:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Buckle 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.

3. Push the latch plate into the buckle until it clicks.Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.4. For passenger seating positions with alap‐shoulder belt and a free‐falling latch plate, pull
the rest of the shoulder belt all the way out of the
retractor to set the lock. When installing a child
restraint using a lap‐shoulder belt and a cinching
latch plate, skip Step 4 and proceed to Step 5.

Additional Factors Affecting System
Operation
Safety belts help keep the passenger in position on the
seat during vehicle maneuvers and braking, which helps
the passenger sensing system maintain the passenger
airbag status. See“Safety Belts”and“Child Restraints”
in the Index for additional information about the
importance of proper restraint use.
If the shoulder portion of the belt is pulled out all the
way, the child restraint locking feature will be engaged.
This may unintentionally cause the passenger sensing
system to turn the airbag off for some adult size
occupants. If this happens, let the belt go back all the
way and start again.
A thick layer of additional material, such as a blanket
or cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates. We recommend that you not use seat covers or other
aftermarket equipment except when approved by GM
for your specific vehicle. See
Adding Equipment to Your
Airbag-Equipped Vehicleon page 2‑91for more
information about modifications that can affect how the
system operates.
The on indicator may be lit if an object, such as a
briefcase, handbag, grocery bag, laptop or other
electronic device, is put on an unoccupied seat.
If this is not desired remove the object from the seat.
{WARNING:
Stowing of articles under the passenger seat or
between the passenger seat cushion and
seatback may interfere with the proper operation
of the passenger sensing system.

Keys
{WARNING:
Leaving children in a vehicle with the ignition key
is dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function with the keys in the ignition and children
could be seriously injured or killed if caught in the
path of a closing window. Do not leave the keys in
a vehicle with children.
The key is used for the ignition and all door locks.
The key has a bar-coded key tag that the dealer/retailer
or qualified locksmith can use to make new keys.
Store this information in a safe place, not in the vehicle.
See your dealer/retailer if a replacement key or
additional key is needed.
Notice:If you ever lock your keys in the vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
