sensor Acura TL 2008 Owner's Guide

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.If there is a problem with the TPMS,
thetirepressuremonitorshowsa
‘‘SYSTEM FUNCTION ERROR’’
message and the tire pressure
readings are not displayed. If this
happens, you will f irst see a system
warning message ‘‘CHECK TPMS
SYSTEM’’ on the multi-inf ormation
display.
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.

If there is a problem with the TPMS,
you will see the above message on
the multi-information display.
Also, the low tire pressure/TPMS
indicator begins to f lash, then stays
on (see page ).
If you see this message, the system
is of f and is not monitoring the tire
pressures. Have the system checked
by your dealer as soon as possible.If you have a f lat tire, the low tire
pressure/TPMS indicator and tire
monitor indicator will come on.
Replace the indicated f lat tire with
thecompactsparetire(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
spare tire pressure to be sure it is
correct. This indicator and the warning
message on the multi-information
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.

go out after inflating the tires to the
specified values, have your dealer

Check the condition of the wiper
blades at least every 6 months.
Replace them if you f ind signs of
cracking in the rubber, areas that are
getting hard, or if they leave streaks
and unwiped areas when used.Raise the wiper arm of f the
windshield.
If you use non-Acura f loor mats,
make sure they f it properly and that

anchors. Do not put additional f loor
mats on top of the anchored mats.
If you remove a f loor mat, make sure

The driver’s and right rear
passenger’s f loor mats that came

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 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 for more informa-
tion.
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.
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.
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.
