The brake system indicator (amber)
on the instrument panel normally
comes on f or a f ew seconds when
you turn the ignition switch to the
ON (II) position. If it stays on af ter
the engine starts, press on the brake
pedal with your f oot several times
until the indicator turns of f . If the
indicator is still on or comes on again
after this procedure, there is a
problem in the brake system
including the electric vacuum pump.
If this happens, the brake pedal
might f eel heavy when you press it.
Have your vehicle checked by your
dealer.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display (see page ).
Your vehicle has an electric vacuum
pump located in the engine
compartment. It enhances the
ef f ectiveness of your vehicle’s brake
system more f requently when you
drive in cold weather or thinner air at
high altitude af ter the engine is
started.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.

Determine f rom the chart on pages

fuse box lid, which fuse or fuses
control that device. Check those
f uses f irst, but check all the f uses
bef ore deciding that a blown f use is
the cause. Replace any blown f uses,
and check if the device works.

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your vehicle.
Leave the blown fuse in that
circuit and have your vehicle
checked by a qualif ied technician.
If the audio f use is removed, the
audio system will disable itself . The
next time you turn on the audio you
will see ‘‘ ’’ on the display.
Use the preset bars or buttons
(depending on models) to enter the
f ive-digit code (see page ).
When the audio system is disabled,
the clock setting in the audio system
will be canceled. You will need to
reset the clock (see page ). If the navigation system f use is
removed, the navigation system will
disableitself.Thenexttimeyouturn
on the ignition switch, the system
will require you to enter a PIN
bef ore it can be used. Ref er to the
Navigation System Owner’s Manual.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.

The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.
The exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
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 three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.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.
