Honda Accord 4D 2003-2006, Owner'S Manual, Page: 483 / 525

This indicator comes on for a few
seconds when you turn the ignition
switch to ON (II). If it comes on at
any other time, it indicates one of the
engine’s emissions control systems
may have a problem. Even though
you may feel no difference in your
vehicle’s performance, it can reduce
your fuel economy and cause your
vehicle to put out excessive
emissions. Continued operation may
cause serious damage.
If you keep driving with the
malfunction indicator lamp on, you
can damage your vehicle’s emissions
controls and engine. Those repairs
may not be covered by your vehicle’s
warranties.
This indicator may also come on
along with the ‘‘D’’ indicator.
If this indicator comes on, safely pull
off the road and turn off the engine.
Restart the engine and watch the
indicator. If it stays on, have your car
checked by the dealer as soon as
possible. Drive moderately until the
dealer has inspected the problem.
Avoid full-throttle acceleration and
driving at high speed.
You should also have the dealer
inspect your car if the indicator
comes on frequently, even though it
goes off when you follow the above
procedure.
