2003 Acura MDX light

However, if the brake pedal does not
f eel normal, you should take
immediate action. Because of the
brake system’s dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will f eel the brake pedal
go down much f arther bef ore the
vehicle begins to slow down, and you
will have to press harder on the
pedal. The distance needed to stop
will be much longer. If it comes on at any other time, it
indicates a problem with the vehicle’s
brake system. In most cases, the
problem is a low f luid level in the
brake f luid reservoir. Press lightly on
the brake pedal to see if it f eels
normal. If it does, check the brake
f luid level the next time you stop at a
service station (see page ). If the
f luid level is low, take the vehicle to
your dealer and have the brake
system inspected f or leaks or worn
brake pads.Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the
longer distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible. (See
on page .)
If you must drive the vehicle a short
distance in this condition, drive
slowly and cautiously.
The Brake System Indicator comes
on when you turn the ignition ON
(II). If the parking brake is not set, it
goes of f af ter you start the engine. If
the parking brake is set, it goes of f
when you f ully release the parking
brake with the engine running. 319

Determine f rom the chart on pagesand , or the diagram on the
f use box lid (the diagram f or the
driver’s side interior f use box is on
the kick panel below the f use box),
which f use or f uses control that
component. Check those f uses f irst,
but check all the f uses bef ore
deciding that a blown f use is not the
cause. Replace any blown f uses and
check the component’s operation.
Turn the ignition switch to LOCK

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 Crank- case Ventilation valve routes them
from the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
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 . 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.
