Store or secure all items that could
be thrown around and hurt
someone during a crash.
Do not put any items on top of the
trunk panel. They can block your
view and be thrown around the
vehicle during a crash.Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.
Be sure items placed on the f loor
behind the f ront seats cannot roll
under the seats and interf ere with
the driver’s ability to operate the
pedals, the proper operation of the
seats, or the proper operation of
the sensors under the seats.
Also, keep all cargo below the
bottom of the windows. If it is
higher, it could interf ere with the
proper operation of the side
curtain airbags. Distribute cargo evenly on the
f loor of the trunk, placing the
heaviest items on the bottom and
as far forward as possible.
If youfolddownthebackseat,tie
down items that could be thrown
about the vehicle during a crash or
sudden stop.
If you carry large items that
prevent you f rom closing the trunk

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.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.
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/TPMS
indicator may come on unexpectedly.
If the tire is flat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
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/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message. It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation

This indicator and the warning
message on the multi-inf ormation
display will go of f , af ter several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualif ied technician.
If you have a f lat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated f lat tire with the compact
sparetire(seepage).
After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. Af ter several miles
(kilometers) driving, this indicator
begins to f lash, then stays on again.
You will also see a ‘‘CHECK TPMS
SYSTEM’’ message on the multi-
inf ormation display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
sparetirepressuretobesureitis
correct.
Also, the low tire pressure/TPMS
indicator begins to f lash, then stays
on (see page ).
If the low tire pressure/TPMS
indicator comes on, or the multi-
inf ormation display shows a
‘‘CHECK TPMS SYSTEM’’ message,
the VSA system automatically turns
on even when the VSA system is
turned of f by pressing the VSA OFF
switch (see page ). If this
happens, you cannot turn the VSA
system of f by pressing the VSA OFF
switch again.
When you restart the vehicle with
thecompactsparetire,theTPMS
system message will also be
displayed on the multi-inf ormation

The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.
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 exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
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 three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles 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.
