the key appears to be undamaged
or the light continues to stay on, try
another ignition key.
If the engine still does not start with

Keys, Doors, and Windows 43At 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 Seats 0 51 .
.
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.

64 Seats and Restraints without airbag inflation, after an
event that exceeds a predetermined
threshold. After turning the ignition
off and then on again, the fuel
system will return to normal
operation; the doors can be locked,
the interior lamps can be turned off,
and the hazard warning flashers can
be turned off using the controls for
those features. If any of these
systems are damaged in the crash
they may not operate as normal.
{ WarningA crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
(Continued) Warning (Continued) Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.
Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts.
.
The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See Vehicle Data Recording and
Privacy 0 278 and Event Data
Recorders 0 278 .
.
Let only qualified technicians
work on the airbag system.
Improper service can mean that
the airbag system will not work
properly. See your dealer for
service.
Roll Bars
{ WarningVehicle rollovers are
unpredictable and dangerous
events that may result in injury or
death regardless of the roll bar or
any other feature. No feature can
fully protect an occupant in every
crash, including a rollover.
The roll bars are under covers
behind the rear head restraints. The
roll bars are designed to deploy if
the sensing system predicts that the
vehicle is about to roll over on its
side. In addition, the roll bars are

Seats and Restraints 67
{ WarningIf the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light 0 101 for more information,
including important safety
information.
If the On Indicator Is Lit for a
Child Restraint The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag
and knee airbag if the system
determines that an infant is present
in a child restraint. If a child restraint
has been installed and the on
indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from
the 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 Front Seat)
0 87 or Securing Child
Restraints (With the Seat Belt
in the Rear Seat) 0 85 .
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

Seats and Restraints 69passenger airbag(s) while a
child restraint or child occupant
is on the seat. If the passenger
airbag(s) are turned on, the on
indicator will be lit.
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. See Airbag
Readiness Light 0 101 for important
safety information.
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 articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system. Servicing the
Airbag-Equipped Vehicle Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information 0 275 .
{ WarningFor up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so. Adding Equipment to the
Airbag-Equipped Vehicle Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal, may keep the airbag system
from working properly.
The operation of the airbag system
can also be affected by changing or
moving any parts of the front seats,
seat belts, the airbag sensing and
diagnostic module, steering wheel,
instrument panel, inner door seals
including the speakers, any of the
airbag modules, roll bars, front
sensors, side impact sensors,
or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system for the
front outboard passenger position,
which includes sensors that are part
of the passenger seat. The
passenger sensing system may not
