At this time the vehicle can be
driven, however the convertible
top is not latched at the rear
and will not be completely
waterproof. See your dealer to
service the convertible top
system.
Cleaning the Convertible Top
The convertible top should be
cleaned often. Do not use
high-pressure car washes as these
may cause water to enter the
vehicle.
Hand wash the convertible top in
partial shade. Use mild soap,
lukewarm water, and a soft sponge.
A chamois or cloth may leave lint on
the top, and a brush can chafe the
threads in the top fabric. Do not use
detergents, harsh cleaners,
solvents, or bleaching agents.
Wet the entire top and let the soap
remain on the fabric for a few
minutes. Wash evenly to avoid
spots or rings. When the top is very
dirty, use a mild foam-type cleaner.
Thoroughly rinse the entire vehicle,
then let the top dry in direct sunlight.To protect the convertible top:
.
Make sure the convertible top is
completely dry before lowering it.
. Do not get any cleaner on the
vehicle's painted finish; it could
leave streaks.
Wind Deflectors
There are two wind deflectors in a
stowage bag behind the rear seat
backrests. See Rear Seats052.
. The small wind deflector can be
placed between the rear head
restraints. .
The large wind deflector can be
placed behind the front seats.
Do not place any objects on the
wind deflectors.
Installing the Small Wind Deflector
1. Remove the cover from the mount between the rear head
restraints by sliding it toward
the driver side of the vehicle.

To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Always stow the seat belt slowly.
If the seat belt webbing returns
quickly to the stowed position, the
retractor may lock and cannot be
pulled out. If this happens, pull the
seat belt straight out firmly to unlock
the webbing, and then release it.
If the webbing is still locked in the
retractor, see your dealer.
Before a door is closed, be sure the
seat belt is out of the way. If a door
is slammed against a seat belt,
damage can occur to both the seat
belt and the vehicle.
Seat Belt Presenter
The seat belt presenters bring the
front outboard seat belts to the front
to help fasten them.
The presenter comes out when:
.The respective door is closed
and the ignition is turned on.
. The ignition is on and the door is
closed.
The presenter may automatically
retract when any of the following
occur:
. The respective door is opened
again.
. The key is removed from the
ignition. .
The respective latch plate is
inserted into the buckle.
. A time-out of 45 seconds
elapsed.
. The vehicle is driven longer than
15 seconds with a speed of
more than 5 km/h (3 mph).
If the seat belt presenter does not
retract automatically, push it back
slightly.Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for front and rear
outboard occupants. Although the
seat belt pretensioners cannot be
seen, they are part of the seat belt
assembly. They can help tighten the
seat 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. Seat belt
pretensioners can also help tighten
the seat belts in a side crash or a
rollover event.

Seats and Restraints 69
1. Turn the vehicle off.
2. Remove the child restraint fromthe vehicle.
3. Remove any additional items from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints (With
the Seat Belt in the Rear Seat)
086 orSecuring Child
Restraints (With the Seat Belt
in the Front Seat) 089.
Make sure the seat belt
retractor is locked by pulling
the shoulder belt all the way
out of the retractor when
installing the child restraint,
even if the child restraint is
equipped with a seat belt lock
off. When the retractor lock is
set, the belt can be tightened
but not pulled out of the
retractor. 5. If, after reinstalling the child
restraint and restarting the
vehicle, the ON indicator is still
lit, turn the vehicle off. Then
slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback
is not pushing the child
restraint into the seat cushion.
Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. See Head Restraints
0 47.
6. Restart the vehicle.
The passenger sensing system may
or may not turn off the airbags for a
child in a child restraint depending
upon the child’s size. It is better to
secure the child restraint in a rear
seat. Never put a rear-facing child
restraint in the front seat, even if the
ON indicator is not lit.If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat,
but the OFF indicator is lit, it could
be because that person is not sitting
properly in the seat or that the child
restraint locking feature is engaged.
Use the following steps to allow the
system to detect that person and
enable the front outboard passenger
frontal airbag and knee airbag: 1. Turn the vehicle off.

2. Remove any additional materialfrom the seat, such as
blankets, cushions, seat
covers, seat heaters, or seat
massagers. Also, remove
laptops, or other electronic
devices.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat
cushion, with legs comfortably
extended.
5. 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-sized occupants. If this
happens, unbuckle the belt, let
the belt go back all the way,
and then buckle the belt again
without pulling the belt out all
the way. 6. Restart the vehicle and have
the person remain in this
position for two to
three minutes after the ON
indicator is lit.
{Warning
If the front outboard passenger
airbag is turned off for an
adult-sized occupant, the airbag
will not be able to inflate and help
protect that person in a crash,
resulting in an increased risk of
serious injury or even death. An
adult-sized occupant should not
ride in the front outboard
passenger seat, if the passenger
airbag OFF indicator is lit.
Additional Factors Affecting
System Operation
Seat 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 “Seat Belts”and“Child Restraints”
in the Index for
additional information about the
importance of proper restraint use.
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
the Airbag-Equipped Vehicle 071
for 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.

Caution
Do not let the LATCH
attachments rub against the
vehicle’s seat belts. This may
damage these parts. If necessary,
move buckled seat belts to avoid
rubbing the LATCH attachments.
Do not fold the rear seatback
when the seat is occupied. Do not
fold the empty rear seat with a
seat belt buckled. This could
damage the seat belt or the seat.
Unbuckle and return the seat belt
to its stowed position, before
folding the seat.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint 078. 1. For rear seating positions,
if the head restraint interferes
with the proper installation of
the child restraint, the head
restraint may be removed. See
“Head Restraint Removal and
Reinstallation” at the end of
this section.
