Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Follow all normal precautions when
parking, including f irmly setting the
parking brake and putting the
transmission in Park. Also, place
wheel chocks at each of the trailer’s
tires.
When driving down hills, reduce
your speed, and shif t down to second
gear. Do not ‘‘ride’’ the brakes, and
remember, it will take longer to slow
downandstopwhentowingatrailer. If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat. When climbing hills, closely watch
your temperature gauge. If it nears
the red (hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shif ts

Maintenance Sub Items
Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at7,500 miles
(12,000 km), then every15,000 miles (24,000 km).
Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive in dusty conditions, replace every 15,000
miles (24,000 km).
Replace dust and pollen filter If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and
from diesel-powered vehicles, replace every 15,000
miles (24,000 km).
Inspect drive belt
Replace transmission and transfer fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher
transmission and transfer temperatures.
This requires transmission and transfer fluid changes
more frequently than recommended by the
Maintenance Minder. If you regularly drive your
vehicle under these conditions, have the transmission
and transfer fluid changed at 60,000 miles
(100,000 km), then every 30,000 miles (48,000 km).
Replace spark plugs
Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), or in very low temperatures (under20°F, 29°C), replace every 60,000 mile (U.S.)/
100,000 km (Canada)

CONT INUED
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.
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.
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.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km). 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 one to two psi (10
to 20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime. 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)willwarnyouwhenatire
pressure is low. See page f or
inf ormation on the TPMS. Add or release air, if needed, to
match the recommended cold tire
pressures on page .384

Every time you check inf lation, you
should also examine the tires for
damage, f oreign objects, and wear.
Youshouldlookfor: For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb.
For additional technical information
about your tires, see page .
If you check the pressure when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to
0.4 kgf /cm ) higher than the cold
reading. This is normal; do not
release air to match the cold
pressure. The tires will be
underinf lated.
Youshouldgetyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.
While tubeless tires have some
ability to self -seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure. 427

To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Ref er tofor more
inf ormation (see page ).
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If this indicator comes on
while driving, or if you see
a ‘‘CHECK EMISSION
SYSTEM’’ message in the multi-
inf ormation display, it means one of
the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If the indicator comes on repeatedly,
even though it may go of f as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘TIGHTEN FUEL CAP’’ message on
the multi-information display.
Tighten the cap until it clicks at least
once (see page ). Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving. 298

The 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.
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 .
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 pages

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 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)
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.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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.
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 converters
are in the exhaust system. Through
chemical reactions, they convert HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.
