Testing of Readiness Codes

Your vehicle has readiness codes as part of the onboard self-diagnostic
system. Some states use these codes for testing to verify whether your
vehicle's emissions components are working properly. The codes may not be
read if you go through the testing just after the battery has gone dead or been
disconnected.
To check if they are set, set the power mode to ON without starting the
engine. The malfunction indicator lamp will come on for several seconds. If it
goes off, the readiness codes are set. If it blinks five times, the readiness codes
are not set.
If you are required to have your vehicle tested before the readiness codes are
set, prepare the vehicle for retesting by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the engine off for 6 hours or more.
3. Make sure the ambient temperature is between 40°F and 95°F (4°C and
35°C).
4. Start the engine without touching the accelerator pedal, and let it idle for
20 seconds.
5. Keep the vehicle in PARK (P). Increase the engine speed to 2,000 rpm, and
hold it there for about 3 minutes.
6. Let the engine idle with your foot off the accelerator for 20 seconds.
7. Select a nearby, lightly traveled major highway where you can maintain a
speed of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on
the highway in DRIVE (D). Do not use 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).
8. Drive in city or 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.
9. Park the vehicle and leave the engine off for 30 minutes .
The readiness codes are erased when the battery is disconnected, and set again
only after several days of driving under a variety of conditions.
If a testing facility determines that the readiness codes are not set, you may be
requested to return at a later date to complete the test.
If the testing facility determines the readiness codes are still not set, see a
dealer.

Paint Care- PMC Edition models only
Dust off the vehicle body after you drive. Regularly inspect your vehicle for
scratches on painted surfaces. Scratches on a painted surface may result in
body rust. If you find a scratch, promptly repair it.
Your vehicle's paint requires up to 60 days from the production date to fully
cure. During this time, avoid applying any wax or paint sealant-type products,
as they could hinder the curing process and affect the paint's durability.
You may polish the paint during these 60 days if the polish does not contain
any wax or paint sealant ingredients. Use only clean, high-quality microfiber
towels or pads, as they are a softer material with less change of scratching the
finish. It is absolutely necessary to keep the microfiber towels or pads properly
cleaned and maintained before using on your vehicle.
Washing the Vehicle
Wash the vehicle regularly. Wash more frequently when driving in the
following conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
Using High Pressure Cleaners
• Keep sufficient distance between the cleaning nozzle and the vehicle body.
• Take particular care around the windows. Standing too close may cause
water to enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment.
Instead, use low pressure water and a mild detergent.
For more information, contact an authorized Acura dealer.
Do not use an automated car wash.
Accessories and Modifications
Accessories
When installing accessories, check the following:
• Do not install accessories on the windshield. They can obstruct your view
and delay your reaction to driving conditions.
