California Proposition 65 Warning
Event Data Recorders
This vehicle is equipped with an event data recorder (EDR). 
The main purpose of an EDR is to record, in certain crash or near 
crash-like situations, such as an air bag deployment or hitting a 
road obstacle, data that will assist  in understanding how a vehicle’s 
systems performed. The EDR is designed to record data related 
to vehicle dynamics and safety systems for a short period of 
time, typically 30 seconds or le ss. The EDR in this vehicle is 
designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were 
buckled/fastened;
• How far (if at all) the driver  was depressing the accelerator 
and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the
circumstances in which crashes and  injuries occur. NOTE: EDR data
are recorded by your vehicle only  if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g., name, gender, age, and
crash location) are recorded. Howe ver, other parties, such as law
enforcement, could combine the  EDR data with the type of
personally identifying data r outinely acquired during a crash
investigation.
WARNING:  This product contains or emits 
chemicals known to the state of California to cause 
cancer and birth defects or other reproductive 
harm.
To read data recorded by an ED R, special equipment is required, 
and access to the vehicle or the ED R is needed. In addition to the 
vehicle manufacturer, other parties,  such as law enforcement, that 
have the special equipment, can re ad the information if they have 
access to the vehicle or the EDR. 
The data belongs to the vehicle ow ner and may not be accessed by 
anyone else except as legally requir ed or with the permission of the 
vehicle owner.
Service Diagnostic Recorders
This vehicle is equipped with serv ice-related devices that record 
information about powertrain perfo rmance. The data can be used 
to verify emissions law requirem ents and/or help technicians 
diagnose and solve service problems.  It may also be combined with 
data from other sources for res earch purposes, but it remains 
confidential.
California Perchlorate Contamination Prevention Act
The airbags, seat belt tensioners , and CR type batteries in this 
vehicle may contain perchlorate materials - special handling may 
apply. See  www.dtsc.ca.gov/hazardouswaste/perchlorate/
