2006 Acura TL REPLACE

Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f .
Remove the cover f rom the f use
box.
Check each of the large f uses in
the under-hood f use box by
looking through the top at the wire
inside. Remove the screws with a
Phillips-head screwdriver.
The vehicle’s f uses are contained in
two fuse boxes. The interior fuse
box is on the driver’s lower lef t side.
To remove the f use box lid, put your
f inger in the notch on the lid, pull it
toward you, and take it out of its
hinges.
The under-hood f use box is on the
driver’s side next to the air cleaner
housing.
If something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pages
and or the diagram on the
fuse box lid, which fuses control that
device. Check those f uses f irst, but
check all the f uses bef ore deciding
that a blown f use is the cause.
Replace any blown f uses, and check
if the device works. 1.

Check the smaller f uses in the
under-hood f use box and all the
fuses in the interior fuse box by
pulling out each one with the f use
puller provided in the under-hood
fuse box.If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem with your
vehicle. Leave the blown fuse in
that circuit, and have your vehicle
checked by a qualif ied mechanic.
If the radio f use is removed, the
audio system will disable itself . The

will see ‘‘CODE’’ in the f requency
display. Use the preset buttons to
enter the f ive-digit code (see page ).
If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.
Look f or a blown wire inside the
f use. If it is burned, replace it with
oneof thesparefusesof thesame
rating or lower.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.

Warning: The temperature grade f or
this tire is established f or a tire that
is properly inf lated and not
overloaded. Excessive speed,
underinf lation, or excessive loading, either separately or in combination,
can cause heat buildup and possible
tire f ailure.
Speed symbol (an
alphabetical code indicating
the maximum speed rating). Load index (a numerical code
associated with the maximum
load the tire can carry). Rim diameter in inches. Tire construction code (R
indicates radial).
Whenever tires are replaced, they
should be replaced with tires of the
same size. Following is an example
of tire size with an explanation of
what each component means. Aspect ratio (the tire’s section
height as a percentage of its
width). Tire width in millimeters. Vehicletype(Pindicates
passenger vehicle).
The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specif ied indoor
laboratory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire f ailure. The
grade C corresponds to a level of
perf ormance, which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Saf ety
Standard No. 109 and No. 139.
Grades B and A represent higher
levels of perf ormance on the
laboratory test wheel than the
minimum required by law. The tire identif ication number (TIN)
is a group of numbers and letters
that look like the f ollowing example
TIN.
Date of manuf acture. Tire type code. Manuf acturer’s
identification mark. This indicates that the tire
meets all requirements of
the U.S. Department of
Transportation.

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.

The three way catalytic converter
contains platinum, palladium, and
rhodium. These metals serve as
catalysts, promoting chemical
reactions to convert the exhaust
gasses without af f ecting the metals.
The catalytic converter is ref erred to
as a three-way catalyst, since it acts
on HC, CO, and NOx. A replacement
unit must be an original Acura part
or its equivalent.
The three way catalytic converter
must operate at a high temperature
for the chemical reactions to take
place. It can set on f ire any
combustible materials that come
near it. Park your vehicle away from
high grass, dry leaves, or other
f lammables.A defective three way catalytic
converter contributes to air pollution,
and can impair your engine’s per-
f ormance. Follow these guidelines to
protect your vehicle’s three way
catalytic converter.
Always use unleaded gasoline.
Even a small amount of leaded
gasoline can contaminate the
catalyst metals, making the three
way catalytic converter inef f ective. Have your vehicle diagnosed and
repaired if it is misf iring, back-
f iring, stalling, or otherwise not
running properly. Keep the engine tuned-up.
