engine Acura RDX 2012 Owners Manual

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.

Testing of Readiness Codes
If you take your vehicle for an
emissions test shortly after the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain‘‘readiness
codes ’’that must be set in the on-
board diagnostics for the emissions
systems. These codes are erased
when the battery is disconnected,
and set again only after several days
of driving under a variety of
conditions. If the testing facility determines that
the readiness codes are not set, you
will be requested to return at a later
date to complete the test. If you must
get the vehicle retested within the
next two or three days, you can
condition the vehicle for retesting by
doing the following.
1. Make sure the gas tank is nearly,
but not completely, full (around
3/4).
2. Make sure the vehicle has been parked with the engine off for 6
hours or more.
3. Make sure the ambient temperature is between 40° and
95°F (4° and 35°C). 4. Without touching the accelerator
pedal, start the engine, and let it
idle for 20 seconds.
5. Keep the vehicle in Park. Increase the engine speed to 2,000 rpm, and
hold it there until the temperature
gauge rises to at least 1/4 of the
scale (about 3 minutes).
6. Without touching the accelerator pedal, let the engine idle for 20
seconds.
7. Drive your vehicle for 30 seconds while accelerating.Emissions Testing49011/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu

8. Select a nearby lightly traveledmajor highway where you can
maintain a speed of 50 to 60 mph
(80 to 100 km/h) for at least 20
minutes. Drive on the highway in
D. Do not use the cruise control.
When traffic allows, drive for 90
seconds without moving the
accelerator pedal. (Vehicle speed
may vary slightly; this is okay.) If
you cannot do this for a continuous
90 seconds because of traffic
conditions, drive for at least 30
seconds, then repeat it two more
times (for a total of 90 seconds). 9. Then drive in city/suburban traffic
for at least 10 minutes. When
traffic conditions allow, let the
vehicle coast for several seconds
without using the accelerator pedal
or the brake pedal.
10. Make sure the vehicle has been parked with the engine off for 30
minutes.
If the testing facility determines the
readiness codes are still not set, see
your dealer.
