Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator in the
instrumental panel and the
appropriate tire position indicator on
thetirepressuremonitoronthe
multi-inf ormation display (see page)tocomeon. For example, if you check and f ill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure
indicator to come on. Or, if you
check and adjust your tire pressure
in cooler conditions, and drive into
extremely hot conditions, the tire
maybecomeoverinflated.However,
the low tire pressure indicator will
not come on if the tires are
overinf lated.
When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. The
multi-inf ormation display also shows
a ‘‘CHECK TIRE PRESSURE’’
message (see page ). You should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure as indicated on the
vehicle’s tire inf ormation placard.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.
Refer to page for tire inflation
guidelines.

Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.If you have a f lat tire, the low tire
pressure and tire monitor indicators
will come on. Replace the indicated
flat tire with the compact spare tire
(see page ).
When all tire pressures are normal,
the multi-information display will
show ‘‘TIRE PRESSURE OK
SYSTEM FUNCTION NORMAL.’’
Each tire, including the spare, should
be checked monthly when cold, and
set to the recommended inf lation
pressure as specif ied on the vehicle
placard and in the owner’s manual
(see page ).
If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire.
When any of the tires has low
pressure, the multi-inf ormation
display shows a ‘‘TIRE PRESSURE
ERROR SYSTEM FUNCTION
NORMAL’’ message (see page ).
After you replace the flat tire with
the spare, the low tire pressure
indicator stays on. This is normal;
the system is not monitoring the
spare tire pressure. Manually check
the spare tire pressure to be sure it
is correct.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

Make sure the rear f loor mats are
properly hooked to the f loor mat
anchors. Your vehicle is equipped
with f ront passenger’s seat weight
sensors. If the rear passenger’s f loor
mat is on the seat rail of the front
passenger’s seat, the sensors will
detect the decreased weight on the
seat and they may not work properly.
If you use a non-Acura f loor mat,
make sure it f its properly and that it
canbeusedwiththefloormat
anchors. Do not put additional f loor
mats on top of the anchored mats.
The floor mats that came with your
vehicle hook over f loor mat anchors.
This keeps the f loor mats f rom
sliding f orward/rearward and
possibly interf ering with the pedals
or making the f ront passenger’s
weight sensor’s inef f ective.

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
comes 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
qualitypartsmayincreasethe
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual f or more informa-
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.
