Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.
Transfer Case and Front Axle
(All-Wheel Drive) Inspection
Every 12 months, or at engine oil change intervals,
check front axle and transfer case and add lubricant
when necessary. A uid loss could indicate a problem.
Check and have it repaired, if needed. Check vent
hose at transfer case for kinks and proper installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chang, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or
conditions result in frequent braking.
Part D: Recommended Fluids and
Lubricants

Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles, has a
number of sophisticated computer systems that monitor
and control several aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle computers to monitor
emission control components to optimize fuel economy,
to monitor conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help the
driver control the vehicle in difficult driving situations.
Some information may be stored during regular
operations to facilitate repair of detected malfunctions;
other information is stored only in a crash event by
computer systems, such as those commonly called event
data recorders (EDR).
In a crash event, computer systems, such as the Airbag
Sensing and Diagnostic Module (SDM) in your vehicle
may record information about the condition of the vehicle
and how it was operated, such as data related to engine
speed, brake application, throttle position, vehicle speed,
safety belt usage, airbag readiness, airbag performance,
and the severity of a collision. This information has been
used to improve vehicle crash performance and may be
used to improve crash performance of future vehicles
and driving safety. Unlike the data recorders on many
airplanes, these on-board systems do not record sounds,
such as conversation of vehicle occupants.To read this information, special equipment is needed
and access to the vehicle or the device that stores
the data is required. GM will not access information
about a crash event or share it with others other than: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.
In addition, once GM collects or receives data, GM may:
use the data for GM research needs,
make it available for research where appropriate
condentiality is to be maintained and need is
shown, or
share summary data which is not tied to a specic
vehicle with non-GM organizations for research
purposes.
Others, such as law enforcement, may have access to
the special equipment that can read the information
if they have access to the vehicle or the device
that stores the data.
