2012 Acura RDX catalytic converter

Low Fuel IndicatorThis indicator comes on as a
reminder that you must refuel soon.
When the indicator comes on, there
are about 2.5 U.S. gal (9.5 L) of fuel
remaining in the tank.
When the needle reaches E, there is
a very small amount of fuel in the
tank.You will also see a
‘‘FUEL LOW ’’
message on the multi-information
display (see page 80).
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
Vehicle Stability Assist
(VSA) System Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position.
It flashes when VSA is active (see
page 395).
If it comes on and stays on at any
other time, there is a problem with
the VSA system. You will also see a
‘‘ CHECK VSA SYSTEM ’’message on
the multi-information display (see
page 80). Take your vehicle to a
dealer to have it checked. Without
VSA, your vehicle still has normal
driving ability, but will not have VSA
traction and stability enhancement.
For more information, see page 395.

Turbo Boost Meter
When the turbo charger is activated,
this meter shows the boost pressure.
Fuel Gauge
This shows how much fuel you have.
It may show slightly more or less
than the actual amount. The needle
returns to the bottom after you turn
off the ignition.Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.

Break-in Period
Help assure your vehicle's future
reliability and performance by paying
extra attention to how you drive
during the first 600 miles (1,000 km).
During this period:●Avoid full-throttle starts and rapid
acceleration.●Avoid hard braking for the first 200
miles (300 km).●Do not change the oil until the
scheduled maintenance time.●Do not tow a trailer.
You should also follow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Fuel Recommendation
Your vehicle is designed to operate
on premium unleaded gasoline with
a pump octane of 91 or higher. If this
octane grade is unavailable, regular
unleaded gasoline with a pump
octane of 87 or higher may be used
temporarily. The use of regular
unleaded gasoline can cause metallic
knocking noises in the engine and
will result in decreased engine
performance. The long-term use of
regular-grade gasoline can lead to
engine damage.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
To help prevent harmful fuel system and
engine deposits, use high quality fuel
containing detergent and additives. 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.

Always use the parking brake when
you park your vehicle. Make sure the
parking brake is set firmly, or your
vehicle may roll if it is parked on an
incline.
Set the parking brake before you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.Parking Tips
●Make sure the moonroof and the
windows are closed.●Turn off the lights.●Place any packages, valuables, etc.
in the cargo area or take them with
you.●Lock the doors and the tailgate.●Never park over dry leaves, tall
grass, or other flammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
●If the vehicle is facing uphill, turn
the front wheels away from the
curb.●If the vehicle is facing downhill,
turn the front wheels toward the
curb.●Check the indicator on the
instrument panel to verify that the
security system is set.●Make sure the parking brake is
fully released before driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.

Onboard Refueling Vapor
Recovery
The onboard refueling vapor
recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister
filled with activated carbon. While
driving, the fuel vapors are drawn
into the engine and burned off.
Exhaust Emissions Controls
The exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
systems work together to control the
engine's combustion and minimize
the amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate from the crankcase and
evaporative emissions control
systems.
PGM-FI SystemThe PGM-FI system uses sequential
multiport fuel injection.
It has three subsystems: air intake,
engine control, and fuel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
fuel to inject under all operating
conditions.Ignition Timing Control SystemThis system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.Three Way Catalytic ConverterThe three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine's exhaust
to carbon dioxide (CO
2), nitrogen
(N
2), and water vapor. Replacement Parts
The emissions control systems are
designed and certified to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent for repairs. Using lower
quality parts may increase the
emissions from your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more
information.
Emissions Controls48811/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu

The three way catalytic converters
contain precious metals that serve as
catalysts, promoting chemical
reactions to convert the exhaust
gasses without affecting the metals.
The catalytic converters are referred
to as three-way catalysts, since they
act on HC, CO, and NOx.
Replacement units must be original
Acura parts or their equivalent.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on fire any
combustible materials that come
near it. Park your vehicle away from
high grass, dry leaves, or other
flammables.
A defective three way catalytic
converter contributes to air pollution,
and can impair your engine's
performance. Follow these
guidelines to protect your vehicle's
three way catalytic converter.●Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter ineffective.
●Keep the engine well maintained.●Have your vehicle diagnosed and
repaired if it is misfiring,
backfiring, stalling, or otherwise
not running properly.
