2005 CHEVROLET COLORADO brake

Ignition Transmission Lock Check
While parked, and with the parking brake set, try to
turn the ignition to LOCK in each shift lever position.
With an automatic transmission, the ignition
should turn to LOCK only when the shift lever is in
PARK (P). The key should come out only in LOCK.
With a manual transmission, the key should come
out only in LOCK.
Contact your GM Goodwrench
®dealer if service is
required.
Parking Brake and Automatic Transmission
Park (P) Mechanism Check
{CAUTION:
When you are doing this check, your vehicle
could begin to move. You or others could be
injured and property could be damaged. Make
sure there is room in front of your vehicle in
case it begins to roll. Be ready to apply the
regular brake at once should the vehicle begin
to move.Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake,
set the parking brake.
To check the parking brake’s holding
ability: With the engine running and transmission
in NEUTRAL (N), slowly remove foot pressure from
the regular brake pedal. Do this until the vehicle
is held by the parking brake only.
To check the PARK (P) mechanism’s holding ability:
With the engine running, shift to PARK (P). Then
release the parking brake followed by the regular
brake.
Contact your GM Goodwrench
®dealer if service is
required.
Underbody Flushing Service

corrosive materials from the underbody. Take care
to clean thoroughly any areas where mud and other
debris can collect.

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.
