Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:●Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.●Cuts, splits, or cracks in the side of
the tire. Replace the tire if you can
see fabric or cord.●Excessive tread wear.
Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread left on
the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.Tire Service Life
The service life of your tires is
dependent on many factors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inflation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inflation pressure
maintenance, it is recommended that
you have annual inspections
performed once the tires reach five
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.
The last four digits of the TIN (tire
identification number) are found on
the sidewall of the tire and indicate
the date of manufacture (See
Tire
Labeling on page 612).

Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the installer perform a dynamic
balance.Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only Acura wheel weights for
balancing.Tire Rotation
To help increase tire life and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.
When the tires are rotated, make
sure the air pressures are checked.Replacing Tires and Wheels
Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire's sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a different
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
The ABS and VSA system work by
comparing the speed of the wheels.
When replacing tires, use the same
size originally supplied with the
vehicle. Tire size and construction
can affect wheel speed and may
cause the system to activate.

It is best to replace all four tires at
the same time. If that is not possible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle's handling.
If you ever replace a wheel, make
sure that the wheel's specifications
match those of the original wheels.
Also be sure you use only TPMS
specific wheels. If you do not, the tire
pressure monitoring system will not
work.
Replacement wheels are available at
your dealer.
Installing improper tires on your
vehicle can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner's manual.

See page 610 for information about
DOT Tire Quality Grading, and page
612 for tire size and labeling
information. Winter Driving
Tires marked
‘‘M + S’’ or ‘‘All
Season ’’on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best performance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.
Snow Tires
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
may be lower than your original tires.
Check with the tire dealer for
maximum speed recommendations.

The sensor on the negative terminal
monitors your vehicle's battery
condition.
If there is a problem with the sensor,
you will see a‘‘CHECK BATTERY
SENSOR’’ message on the multi-
information display. Have the vehicle
checked by your dealer.
Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent further
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician. WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (- ) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
If your vehicle's battery is
disconnected or goes dead, the audio
system may disable itself. The next
time you turn on the radio, you will
see ‘‘ENTER CODE ’’in the
frequency display. Use the preset
buttons to enter the code (see page

If you need to park your vehicle for
an extended period (more than 1
month), there are several things you
should do to prepare it for storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.●Fill the fuel tank.●Wash and dry the exterior
completely.●Clean the interior. Make sure the
carpeting, floor mats, etc., are
completely dry.●Leave the parking brake off. Put
the transmission in Park.
●Block the rear wheels.●If the vehicle is to be stored for a
longer period, it should be
supported on jackstands so the
tires are off the ground.●Leave one window open slightly (if
the vehicle is being stored
indoors).●Disconnect the battery.●Support the front and rear wiper
blade arms with a folded towel or
rag so they do not touch the
windshield.●To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehicle body wax to the painted
surfaces that mate with the door
and tailgate seals.
●Cover the vehicle with a
‘‘breathable’’ cover, one made from
a porous material such as cotton.
Non-porous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.●If possible, periodically run the
engine until it reaches full
operating temperature (the cooling
fans cycle on and off twice).
Preferably, do this once a month.

Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label.
(If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
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
significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure.Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect 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-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.

The burning of gasoline in your
vehicle's engine produces several
byproducts. Some of these are
carbon monoxide (CO), oxides of
nitrogen (NOx), and hydrocarbons
(HC). Gasoline evaporating from the
tank also produces hydrocarbons.
Controlling the production of NOx,
CO, and HC is important to the
environment. Under certain
conditions of sunlight and climate,
NOx and HC react to form
photochemical‘‘smog. ’’Carbon
monoxide does not contribute to
smog creation, but it is a poisonous
gas. The Clean Air Act
The United States Clean Air Act
ꭧ
sets standards for automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
work and what to do to maintain
them. This section summarizes how
the emissions controls work.
Scheduled maintenance is on page
542.ꭧIn Canada, Acura vehicles comply
with the Canadian emission
requirements, as specified in an
agreement with Environment
Canada, at the time they are
manufactured. Crankcase Emissions Control
System
Your vehicle has a positive crankcase
ventilation system. This keeps
gasses that build up in the engine's
crankcase from going into the
atmosphere. The positive crankcase
ventilation valve routes them from
the crankcase back to the intake
manifold. They are then drawn into
the engine and burned.
Evaporative Emissions Control
System
As gasoline evaporates in the fuel
tank, an evaporative emissions
control canister filled with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is off. After
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
