Convertible Top
The vehicle’s convertible top should be cleaned
often. However, high pressure car washes
may cause water to enter your vehicle.
When you hand wash the top, do it in partial
shade. Use a 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 vehicle and wash the top evenly
to avoid spots or rings. Let the soap remain on the
fabric for a few minutes. When the top is really
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:
After you wash the vehicle, make sure the
top is completely dry before you lower it.
Do not get any cleaner on the vehicle’s painted
nish; it could leave streaks.
If you decide to go through an automatic car
wash, ask the manager if the equipment
could damage your top.
Aluminum or Chrome-Plated
Wheels and Trim
Your vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth
with mild soap and water. Rinse with clean water.
After rinsing thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:Chrome wheels and other chrome
trim may be damaged if you do not wash
your vehicle after driving on roads that have
been sprayed with magnesium, calcium or
sodium chloride. These chlorides are used
on roads for conditions such as ice and dust.
Always wash your vehicle’s chrome with
soap and water after exposure.
Notice:If you use strong soaps, chemicals,
abrasive polishes, cleaners, brushes, or
cleaners that contain acid on aluminum or
chrome-plated wheels, you could damage the
surface of the wheel(s). The repairs would
not be covered by your warranty. Use
only approved cleaners on aluminum or
chrome-plated wheels.

The surface of these wheels is similar to the
painted surface of your vehicle. Do not use strong
soaps, chemicals, abrasive polishes, abrasive
cleaners, cleaners with acid, or abrasive cleaning
brushes on them because you could damage
the surface. Do not use chrome polish on
aluminum wheels.
Notice:Using chrome polish on aluminum
wheels could damage the wheels. The repairs
would not be covered by your warranty.
Use chrome polish on chrome wheels only.
Use chrome polish only on chrome-plated wheels,
but avoid any painted surface of the wheel, and
buff off immediately after application.
Notice:If you drive your vehicle through an
automatic car wash that has silicone carbide
tire cleaning brushes, you could damage
the aluminum or chrome-plated wheels.
The repairs would not be covered by your
warranty. Never drive a vehicle equipped with
aluminum or chrome-plated wheels through
an automatic car wash that uses silicone
carbide tire cleaning brushes.Tires
To clean the tires, use a stiff brush with
tire cleaner.
Notice:Using petroleum-based tire dressing
products on your vehicle may damage the
paint nish and/or tires. When applying a
tire dressing, always wipe off any overspray
from all painted surfaces on your vehicle.
Finish Damage
Any stone chips, fractures or deep scratches in
the nish should be repaired right away.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer
or other service outlets. Larger areas of nish
damage can be corrected in your dealer’s
body and paint shop.

Vehicle Data Recording and
Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the
vehicle’s performance and how it is driven. For
example, your vehicle uses computer modules to
monitor and control engine and transmission
performance, to monitor the conditions for airbag
deployment and deploy airbags in a crash
and, if so equipped, to provide anti-lock braking to
help the driver control the vehicle. These
modules may store data to help your dealer/retailer
technician service your vehicle. Some modules
may also store data about how you operate
the vehicle, such as rate of fuel consumption or
average speed. These modules may also
retain the owner’s personal preferences, such as
radio pre-sets, seat positions, and temperature
settings.
Event Data Recorders
Some information about your vehicle’s
performance and how it is driven may be recorded
on various modules if a crash occurs. Some
people refer to these modules asevent data
recorders (EDRs). These modules may record
several seconds of pre-crash and crash data, such
as data related toengine speed, brake
application, throttle position, vehicle speed,
yaw rate, steering wheel angle, lateral
acceleration, safety belt usage, airbag
readiness, airbag performanceandthe severity
of the collision.Unlike the ight data recorders
on airplanes, these modules do not record sounds
or conversations.
To retrieve this data, special equipment and
access to the vehicle or the module that stores the
data are required. Certain data may also be
sent to or retrieved by OnStar
®(see below). GM
will not access this information or share it with
others except: with the consent of the vehicle
owner or, if the vehicle is leased, with the consent
of the lessee; in response to an official request
of police or similar government office; as part
of GM’s defense of litigation through the discovery
process; or, as required by law.
