2008 SUZUKI SX4 engine

12-3GENERAL INFORMATION
80J21-03E
On-Board Vehicle Computers
and Event Data RecordersYour vehicle is equipped with on-board
computer systems which monitor and
control several aspects of vehicle per-
formance, including the following:
 Emission-related components and
engine parameters such as engine
speed and throttle position are moni-
tored to provide emissions control
and to provide optimum fuel econ-
omy. Your vehicle also has an on-
board diagnostic system which mon-
itors and records information about
emission-related malfunctions.
 Signals from various sensors are
monitored to provide air bag deploy-
ment.
 If your vehicle is equipped with
antilock brakes, conditions such as
vehicle speed and brake perfor-
mance are monitored, so that the
ABS system can provide effective
antilock braking. If your vehicle has
an Electronic Stability Program
(ESP
®) system, conditions such as
yaw rate, lateral acceleration, and
brake fluid pressure are monitored,
so that the ESP
® system can help
the driver control the vehicle in diffi-
cult driving situations.
Some information may be stored by
the on-board computers during normaloperation of the vehicle. This stored
information can assist technicians in
repairing the vehicle when malfunc-
tions occur. Other information is stored
only in the event of crash, by computer
systems that are commonly called
Event Data Recorders (EDRs).
In a crash event, EDRs such as the
Airbag Sensing and Diagnostic Mod-
ule (SDM) in your vehicle may record
information about the condition of the
vehicle and how it was operated, such
as data related to airbag readiness,
airbag performance, safety belt usage,
and the severity of the collision. These
data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur and lead to
the designing of safer vehicles. The
SDM in your vehicle does not collect
or store personal information.
To read the stored information, special
equipment is needed and access to
the vehicle or storage device is
required. SUZUKI will not access infor-
mation about a crash event or share it
with others other than with the consent
of the vehicle owner or lessee, in
response to an official request from
the police or similar government office,
as part of SUZUKI’s defense of litiga-
tion through the discovery process, or
as required by law.In addition, once SUZUKI collects or
receives data, SUZUKI may use the
data for research conducted by
SUZUKI, make the data available for
outside research if need is shown and
confidentiality is assured, or make
summary data which does not identify
specific vehicles available for outside
research.
Others, such as law enforcement per-
sonnel, may have access to the spe-
cial equipment that can read the
information if they have access to the
vehicle or storage device.
Reporting Safety Defects: NO
