The HomeLink Universal
Transceiver built into your vehicle
canbeprogrammedtooperateupto
three remotely controlled devices
around your home, such as garage
doors, lighting, or home security
systems. Always ref er to the opening
instructions and saf ety inf ormation
that came with your garage door
opener or other equipment you
intend to operate with the HomeLink
Universal Transceiver. If you do not
have this information, contact the
manuf acturer of the equipment.
If you are training the second or
third buttons, go directly to Step 1.
If you are training HomeLink to
operate a garage door or gate, you
should unplug the motor f or that
device during training. Repeatedly
pressing the remote control button
could burn out the motor.
The HomeLink transceiver stores
the code in a permanent memory.
There should be no need to retrain
HomeLink if your vehicle’s battery
goes dead or is disconnected. If your
garage door opener was
manuf actured bef ore April 1982, you
may not be able to program
HomeLink to operate it. They do not
have the safety feature that causes the motor to stop and reverse if an
obstacle is detected during closing,
increasing the risk of injury.
If you just
received your vehicle and have not
trained any of the buttons in
HomeLink bef ore, you should erase
any previously learned codes bef ore
training the first button.
Todothis,pressandholdthetwo
outside buttons on the HomeLink
transceiver for about 20 seconds,
until the red light f lashes. Release
the buttons, then proceed to Step 1.

page .
To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch. Press the brake
pedal to shift from Park to Reverse.
To shif t f rom Reverse to Neutral,

Your vehicle has a reverse lockout so
you cannot accidentally shif t to
Reverse from Neutral or any other
driving position when the vehicle
speed exceeds 7 9 mph (12 14
km/h).
If you cannot shif t to Reverse when
the vehicle is stopped, press the
brake pedal and slowly shift to
Neutral, and then to Reverse.
If there is a problem in the reverse
lockout system, or your vehicle’s

must be towed with all f our wheels
on the ground (f lat towing).
When purchasing a tow bar, make
sure you select a reputable
manuf acturer. Follow the

Check the condition of the battery
monthlybylookingatthetest
indicator window. The label on the
battery explains the test indicator’s
colors. Check the terminals f or corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
f urther corrosion.
If additional battery maintenance is
needed, see your Acura dealer or a
qualif ied technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds. If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.

TEST INDICATOR WINDOW
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
mechanic do the battery
maintenance.

If you need to park your vehicle f or
an extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.Fill the f uel tank.
Change the engine oil and f ilter.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
Leave the parking brake off. Put
the transmission in Park. Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
If you store your vehicle f or 12
months or longer, have your Acura
dealer perf orm the inspections called
f or in the 24 months/30,000 miles
(48,000 km) maintenance schedule
(Normal Conditions) as soon as you
take it out of storage (see page ).
The replacements called f or in the
maintenance schedule are not
needed unless the vehicle has
actually reached that time or mileage. 199

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
are very dim or don’t light at 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 ).
