Make sure the rear f loor mats are
properly hooked to the f loor mat
anchors. Your vehicle is equipped
with front passenger’s seat weight
sensors. If the rear passenger’s f loor
mat is on the seat rail of the f ront
passenger’s seat, the sensors will
detect the decreased weight on the
seat, and they may not work properly. The floor mats that came with your
vehicle hook over the f loor mat
anchors. This keeps the f loor mats
f rom sliding f orward (possibly
interf ering with the pedals), or
backwards (making the f ront
passenger’s weight sensors
inef f ective).If you remove a f loor mat, make sure
tore-anchoritwhenyouputitback
in your vehicle.
If you use non-Acura f loor mats,
make sure they f it properly and that
theycanbeusedwiththefloormat
anchors. Do not put additional f loor
mats on top of the anchored mats.
To lock or unlock each anchor, turn
the knob.

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These f our 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 f rom the crankcase and
evaporative emissions control
systems.
The PGM-FI system uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
f uel to inject under all operating
conditions.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned.The emissions control systems are
designed and certif ied 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 f or repairs. Using lower
quality parts may increase the
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more inf orma-
tion. The three way catalytic converters
are in the exhaust system. Through
chemical reactions, they convert HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.
