Quick Reference Guide
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 less. 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. However, other parties, such as law
enforcement, could combine the EDR data with the type of
personally identifying data routinely 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 EDR, special equipment is required,
and access to the vehicle or the EDR is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement, that
have the special equipment, can read the information if they have
access to the vehicle or the EDR.
The data belongs to the vehicle owner and may not be accessed by
anyone else except as legally required or with the permission of the
vehicle owner.
Service Diagnostic Recorders
This vehicle is equipped with service-related devices that record
information about powertrain performance. The data can be used
to verify emissions law requirements and/or help technicians
diagnose and solve service problems. It may also be combined with
data from other sources for research 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/
As you read this manual, you will find information that is preceded
by a symbol. This information is intended to help you avoid
damage to your vehicle, other property, or the environment.

Airbag Care
You do not need to, and should not, perform any maintenance on or replace any
airbag system components yourself. However, you should have your vehicle
inspected by a dealer in the following situations: ■When the airbags have deployed
If an airbag has inflated, the control unit and other related parts must be replaced.
Similarly, once an automatic seat belt tensioner has been activated, it must be
replaced. ■ When the vehicle has been in a moderate-to-severe collision
Even if the airbags did not inflate, have your dealer inspect the following: the driver’s
seat position sensor, weight sensors in the passenger’s seat, front seat belt
tensioners, and each seat belt that was worn during the crash. ■ Do not remove or modify a front seat without consulting a dealer
This would likely disable the driver's seat position sensor or the weight sensors in the
passenger's seat. If it is necessary to remove or modify a front seat to accommodate
a person with disabilities, contact a Honda dealer, or for U.S. vehicles, American
Honda Automobile Customer Service at 800-999-1009 and for Canadian vehicles,
Honda Canada Customer Relations at 888-9-HONDA-9.
1Airbag Care
We recommend against the use of salvaged airbag
system components, including the airbag, tensioners, sensors, and control unit.

Fuel Information ■Fuel recommendation
Use of a lower octane gasoline can cause a persistent, heavy metallic knocking noise
that can lead to engine damage.
Use of a lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of a gasoline with a pump octane less than 87 can lead to engine damage. ■ Top tier detergent gasoline
Because the level of detergency and additives in gasoline vary in the market, Honda
endorses the use of “TOP TIER Detergent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard jointly established by leading automotive
manufacturers to meet the needs of today’s advanced engines.
Unleaded gasoline, pump octane number 87 or higher
Unleaded premium gasoline, pump octane number 91 or higher
1Fuel Information
NOTICE
We recommend quality gasoline containing
detergent additives that help prevent fuel system and
engine deposits. In addition, in order to maintain
good performance, fuel economy, and emissions
control, we strongly recommend the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is available.
Use of gasoline with these additives may adversely
affect performance, and cause the malfunction
indicator lamp on your instrument panel to come on.
If this happens, contact a dealer for service.
Some gasoline today is blended with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 10% ethanol
by volume. Do not use gasoline containing methanol.
If you notice any undesirable operating symptoms, try
another service station or switch to another brand of
gasoline.1.8  engine models
