This indicator has two f unctions:This indicator comes on when you
turn the ignition switch to ON (II).
It is a reminder to check the
parking brake. A beeper sounds if
you try to drive with the parking
brake not fully released. Driving
with the parking brake not fully
released can damage the brakes
and tires. This indicator comes on f or a f ew
seconds when you turn the ignition
switch to ON (II). It will go of f if you
have inserted a properly-coded
ignition key. If it is not a properly-
coded key, the indicator will blink
and the engine will not start (see
page ).
This indicator also blinks several
times when you turn the ignition
switch f rom ON (II) to ACCESSORY
(I) or LOCK (0).
This indicator normally comes on f or
a f ew seconds when you turn the
ignition switch to ON (II), and when
the ignition switch is turned to
START (III). If it comes on at any
other time, there is a problem in the
ABS. If this happens, have your
vehicle checked by your dealer. With
the indicator on, your vehicle still
has normal braking ability but no
anti-lock. For more inf ormation, see
page .
If the indicator remains on after
you have f ully released the
parking brake while the engine is
running, or if it comes on while
driving, it can indicate a problem
in the brake system. For complete
inf ormation, see page .

need this key number if you ever
have to get a lost key replaced. Use
only Acura-approved key blanks.
These keys contain electronic
circuits that are activated by the
Immobilizer System. They will not
work to start the engine if the
circuits are damaged.
Protect the keys f rom direct

The Immobilizer System protects
your vehicle f rom thef t. If an
improperly-coded key (or other
device) is used, the engine will not
start.
When you turn the ignition switch to
ON (II), the Immobilizer System
indicator should come on f or a f ew
seconds, then go out. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to
LOCK (0), remove the key, reinsert
it, and turn the switch to ON (II)
again.The system may not recognize your
key’s coding if another immobilizer
key or other metal object (i.e. key
f ob) is near the ignition switch when
you insert the key.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle undriveable.
If you have lost your key and you
cannot start the engine, contact your
dealer. If the system repeatedly does not
recognize the coding of your key,
contact your dealer.As required by the FCC:

Apply the parking brake.
In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
Make sure the shif t lever is in
Park. Press on the brake pedal.Without touching the accelerator
pedal, turn the ignition key to the
START (III) position. Do not hold
the key in START (III) f or more
than 15 seconds at a time. If the
engine does not start right away,
pause f or at least 10 seconds
bef ore trying again.If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
If the engine still does not start,
press the accelerator pedal all the
way down and hold it there while
starting in order to clear f looding.
If the engine still does not start,
return to step 5.

Immobilizer System T he immobilizer system protects your
vehicle f rom thef t. If an improperly-
coded key (or other device) is used, the
engine’s f uel system is disabled. See
on page .
The engine is harder to start in cold
weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400
meters) adds to this problem.

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things: Check the transmission interlock.
The transmission must be in Park
orNeutralorthestarterwillnot
operate.
Turn the ignition switch to ON (II).
Turn on the headlights, and check
their brightness. If the headlights
areverydimordonotcomeonat
all, the battery is discharged. See
on page .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereis
probably something wrong with
the electrical circuit f or the
ignition switch or starter motor.
You will need a qualif ied
technician to determine the
problem (see
on page ). If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
f rom a booster battery (see page
).
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run. Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the dash panel to blink
rapidly(seepage ).
