Check the level on the side of the
reservoir when the engine is cold.
The f luid should be between the
UPPER LEVEL and LOWER LEVEL.
If not add power steering f luid to the
UPPER LEVEL mark. Always use Honda Power Steering
Fluid. You may use another power
steering f luid as an emergency
replacement, but have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
The timing belt should be replaced
at the intervals shown in the
maintenance minder schedule.
A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently, and have
the system inspected as soon as
possible.
If you are not sure how to add
f luid, contact your dealer.
Pour the f luid slowly and caref ully so
you do not spill any. Clean up any
spills immediately; it could damage
components in the engine
compartment. Replace the timing belt every 60,000
miles (U.S.) or every 100,000 km
(Canada) if you regularly drive your
vehicle in any of the f ollowing
conditions:
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).
Frequently tow a trailer.

If your seat belts get dirty, use a sof t
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air-dry bef ore
you use the vehicle.

Have your dealer replace the filter
when this service is indicated by a
maintenance message on the multi-
inf ormation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the f low f rom
theclimatecontrolsystembecomes
less than usual.
Dirt build-up around the openings of
the seat belt anchors can cause the
belts to retract slowly. Wipe the
openings with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.

To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced. Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly.
Even though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it immediately with a tire gauge.
Thetirepressuremonitoringsystem
(TPMS) warns you when a tire
pressure is low. See page f or
more inf ormation. Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this

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.
Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.
Youshouldlookfor:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherof theseconditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord.
Excessive tread wear. The service lif e of your tires is
dependent on many f actors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inf lation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inf lation pressure
maintenance, it is recommended that
you have annual inspections
perf ormed once the tires reach f ive
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 f our digits of the TIN (tire
identif ication number) are f ound on
the sidewall of the tire and indicate
the date of manufacture (See
on page ).
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 lef t on
the tire.

In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you f eel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed f rom the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comf ort and tire lif e. For best results,
have the installer perform a dynamic
balance.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 dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
To help increase tire lif e 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. TheABSworksbycomparingthe
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.
When the tires are rotated, make
sure the air pressures are checked.

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.

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 .
