downhill. Keeping your foot on the regular
brake, set the parking brake.

With the engine running and transaxle in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.

your dealer for specic information about
availability. All Courtesy Transportation

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. If your vehicle is
equipped with StabiliTrak
®, steering performance,
including yaw rate, steering wheel angle, and
lateral acceleration, is also recorded. 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.
