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.

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.
• Do not install any accessories over areas marked SRS AIRBAG, on the sides
or backs of the front seats, on front or side pillars, or near the side windows.
Accessories installed in these areas may interfere with proper operation of
the vehicle's airbags or may be propelled into your or another occupant if
the airbags deploy.
• Be sure electronic accessories do not overload electrical circuits or interfere
with proper operation of your vehicle.

• Before installing any electronic accessory, have the installer contact a dealer
for assistance. If possible, have a dealer inspect the final installation.
