Your dealer and the service manual have
information about the location of the airbag
modules and sensors, sensing and diagnostic
module, and airbag wiring along with the
proper replacement procedures.
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 operate
properly if the original seat trim is replaced
with non-GM covers, upholstery or trim,
or with GM covers, upholstery or trim
designed for a different vehicle. Any object,
such as an aftermarket seat heater or a
comfort-enhancing pad or device, installed
under or on top of the seat fabric, could
also interfere with the operation of the
passenger sensing system. This could either
prevent proper deployment of the passenger
airbag(s) or prevent the passenger sensing system from properly turning off the
passenger airbag(s). See
Passenger Sensing
System 056.
If the vehicle must be modified because you
have a disability and have questions about
whether the modifications will affect the
vehicle’s airbag system, or if you have
questions about whether the airbag system
will be affected if the vehicle is modified for
any other reason, call Customer Assistance.
See Customer Assistance Offices 0321.
Airbag System Check
The airbag system does not need regularly
scheduled maintenance or replacement.
Make sure the airbag readiness light is
working. See Airbag Readiness Light 084.
Caution
If an airbag covering is damaged, opened,
or broken, the airbag may not work
properly. Do not open or break the airbag
coverings. If there are any opened or
broken airbag coverings, have the airbag
covering and/or airbag module replaced.
For the location of the airbags, see Where
Are the Airbags? 053. See your dealer for
service.
Replacing Airbag System Parts
after a Crash
{Warning
A crash can damage the airbag systems
in the vehicle. A damaged airbag system
may not properly protect you and your
passenger(s) in a crash, resulting in
serious injury or even death. To help
make sure the airbag systems are

Maintenance
Passenger Compartment Air Filter
The passenger compartment air filter
reduces dust, pollen, and other airborne
irritants from outside air that are pulled into
the vehicle. Reductions in airflow, which
may occur more often in dusty areas,
indicate that the filter may need to be
replaced. See
Maintenance Schedule 0306.
Caution
Driving without a passenger compartment
air filter in place can cause water and
small particles, like paper and leaves, to
be pulled into your climate control
system which may cause damage to it.
Make sure you always replace the old
filter with a new one.
The passenger compartment air filter is
located under the hood between the battery
and windshield. See Underhood
Compartment Overview 0234.

serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See Maintenance Schedule
0 306.

Dual Clutch Transmission Fluid
How to Check Dual Clutch Transmission
Fluid
It is not necessary to check the transmission
fluid level. A transmission fluid leak is the
only reason for fluid loss. If a leak occurs,
take the vehicle to the dealer and have it
repaired as soon as possible. The vehicle is not equipped with a
transmission fluid level dipstick. There is a
special procedure for checking and changing
the transmission fluid. Because this
procedure is difficult, this should be done at
the dealer. Contact the dealer for additional
information or the procedure can be found
in the service manual. To purchase a service
manual, see
Publication Ordering
Information 0327.
Caution
Use of the incorrect transmission fluid
may damage the vehicle, and the
damage may not be covered by the
vehicle warranty. Always use the correct
transmission fluid. See Recommended
Fluids and Lubricants 0310.
Change the fluid and external canister filter
at the proper intervals. See Maintenance
Schedule 0306. Be sure to use the correct
fluid. See Recommended Fluids and
Lubricants 0310.
Dual Clutch Transmission Fluid Life
System
When to Change the Dual Clutch
Transmission Fluid
This vehicle has a computer that indicates
when to change the transmission fluid. This
is based on a combination of factors which
include temperature and miles driven. Based
on driving conditions, the mileage at which
a fluid change is indicated can vary
considerably. For the fluid life system to
work properly, the system must be reset
every time the fluid is changed. When the
system has calculated that fluid life has
been diminished, it indicates that a fluid
change is necessary. A CHANGE
TRANSMISSION FLUID SOON message comes
on. Change the fluid as soon as possible
within the next 1 000 km (600 mi). Failure
to change transmission fluid at required
intervals could lead to suboptimal
transmission performance. Your dealer has
trained service technicians who will change
the fluid and reset the system. If the system
is ever reset accidentally, the fluid must be
changed 72 000 km (45,000 mi) after the
last fluid change.
