The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
Quality grades can be f ound where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:

T readwear 200

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.
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 car
tires must meet under the Federal
Motor Vehicle Saf ety Standard No.
109. Grades B and A represent
higher levels of perf ormance on the
laboratory test wheel than the
minimum required by law.

The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
Load index (a numerical code
associated with the maximum
load the tire can carry).
Speed symbol (an
alphabetical code indicating
the maximum speed rating).
Whenever tires are replaced, they
should be replaced with tires of the
same size. The f ollowing is an
exampleof tiresizewithan
explanation of what each component
means.
Vehicletype(Pindicates
passenger vehicle).
Tire width in millimeters.
Aspect ratio (the tire’s section
height as a percentage of its
width).
Tire construction code (R
indicates radial).
Rim diameter in inches. The tire identif ication number (TIN)
is a group of numbers and letters
that look like the f ollowing example.
TIN is located on the sidewall of the
tire.
This indicates that the tire
meets all requirements of
the U.S. Department of
Transportation.

Each tire, including the spare (if
provided), should be checked
monthly when cold and inf lated to
the inf lation pressure recommended
by the vehicle manuf acturer on the
vehicle placard or tire inf lation
pressure label.
(If your vehicle has tires of a
dif f erent size than the size indicated
on the vehicle placard or tire
inf lation pressure label, you should
determine the proper tire inf lation
pressure f or those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale
when one or more of your tires is
signif icantly under-inf lated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inf late them to
the proper 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.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if under-inf lation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.

Always check the TPMS malf unction
telltale af ter replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to f unction
properly.
Your vehicle has also been equipped
with a TPMS malf unction indicator
to indicate when the system is not
operating properly. The TPMS
malf unction indicator is combined
with the low tire pressure telltale.
When the system detects a
malf unction, the telltale will f lash f or
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
When the malf unction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended.
TPMS malf unctions may occur f or a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS f rom
f unctioning properly.

ÎThe burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas. The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page
.
In Canada, Acura vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The positive crankcase ventilation valve routes
them from the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The onboard ref ueling vapor
recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
