4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you continue driving (see Emergenc y
Towin g on page 292).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page170). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check- ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes off. 10. Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90° F/32° C). Add
coolant to the radiator up to the
base of the filler neck. If you do
not have the proper coolant
mixture available, you can add
plai
n water. Remember to have
the cooling system drained and
refilled with the proper mixture as
soon as you can.
11. Put the radiator cap back
on
tightly. Run the engine and watch
the temperature gauge. If it goes
back t

o the red mark, the engine
needs repair. (See Emergenc y
Towin g o

n page 29
2.)
12. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back
on

tightly.

Removing the radiator cap

while the engine is hot can

cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.

Chargin
g Syste m Indicato r

This indicator should come on when the ignition switch is ON (II), and goout after the engine starts. If it
comes on brightly when the engine
is running, it indicates that the charging system has stopped
charging the battery. Immediately turn off all electrical
accessories: radio, climate control,
rear defogger, cruise control, etc.
Try not to use other electrically- operated controls such as the power
windows. Keep the engine running and take extra care not to stall it.
Starting the engine will discharge
the battery rapidly. By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged
to keep the engine running. Drive to a service station or garage where
you can get technical assistance.

DO
T Tir e Qualit y Gradin g (U.S . Cars )
The tires on your car meet all U.S. Federal Safety Requirements. All
tires are also graded for treadwear,
traction, and temperature perform- ance according to Department of
Transportation (DOT) standards.
The following explains these
gradings.

Unifor m Tir e Qualit y Gradin g

Quality grades can be found where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example:

Treadwea r 20 0

Tractio n A A

Temperatur e A
Treadwea
r

The treadwear grade is a compara- tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified 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 performance of
tires depends upon the actual condi-
tions of their use, however, and may depart significantly from the norm
due to variations in driving habits,
service practices, and differences in
road characteristics and climate.
Tractio
n

The traction grades, from highest to lowest, are AA, A, B, and C. Those
grades represent the tire's ability tostop on wet pavement as measured
under controlled conditions onspecified government test surfaces
of asphalt and concrete. A tire
marked C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based onstraight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.

Emission
s Control s

The burning of gasoline in your car'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.
Th
e Clea n Ai r Ac t

The United States Clean Air Act*
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
206.

* In Canada, Acura vehicles comply

with the Canadian Motor Vehicle
Safety Standards (CMVSS) for

Emissions valid at the time they are

manufactured.

Crankcas e Emission s Contro l
Syste m
Your car has a Positive Crankcase
Ventilation System. This keeps gasses that build up in the engine'scrankcase 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.
Evaporativ e Emission s Contro l
Syste m
As gasoline evaporates in the fuel tank, an evaporative emissionscontrol 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.
Onboar d Refuelin g Vapo r
Recover y
The Onboard Refueling Vapor Recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister
filled with activated carbon. While driving, the fuel vapors are drawn
into the engine and burned off.
