2015 Acura RDX Emissions

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 assi st 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 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 ED R, 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 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 requ ired 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 perform ance. 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/
As you read this manual, you will find information that is preceded

Refueling
Fuel Information
■Fuel recommendation
Use of lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of gasoline with a pump octane less than 87 can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additi ves in gasoline vary in the market, Acura
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.
Qualifying gasoline retailers will, in most cases, identify their gasoline as having met
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is
guaranteed to contain the proper level of de tergent additives and be free of metallic
additives. The proper level of detergent additives, and absence of harmful metallic
additives in gasoline, help avoid build-up of deposits in your engine and emission
control system.
For further important fuel-related informati on for your vehicle, or on information on
gasoline that does not contain MMT, visit Acura Owners at owners.acura.com In
Canada, visit www.acura.ca for additional informati on on gasoline. For more
information on top tier gasoline, visit www.toptiergas.com.
■Fuel tank capacity: 16 US gal (60.5 liters)
Unleaded premium gasoline, pump octane number 91 or higher
1Fuel Information
NOTICE
We recommend quality ga soline 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 reco mmend 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, a nd cause the malfunction
indicator lamp on your inst rument 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 15% ethanol
by volume. Do not use gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.

dealer.
■What to do when the indicator lamp blinks
Park the vehicle in a safe place with no flammable items and wait at least
ten minutes or more with the engine stopped until it cools.
■The message appears on when:
An evaporative system leak is detected. This may be caused by the fuel fill cap being
loose or not being installed.
■What to do when the message appears:
1. Stop the engine.
2. Check that the fuel fill cap is fully installed.
u If not, loosen the cap, and then reti ghten it until it clicks at least once.
3. Drive for several days of normal driving.
u The message should go off.
■When the malfunction indicator lamp comes on
Malfunction indicator lamp comes on if the system continues to detect a leak of
gasoline vapor. If this happens, check the fuel fill cap using the procedures described
above.
