2012 Acura MDX ECU

If your vehicle’s battery is disconnected
or goes dead, the audio system
disables itself. If this happens, you will
see‘‘ENTER CODE’’in the frequency
display next time you turn on the
system. Use the preset buttons (Icons
on models with navigation system) to
enter the five-digit code. The code is on
the Anti-theft Identification Card
included in your owner’s manual kit.
When it is entered correctly, the radio
will start playing.
The Anti-theft Identification Card also
lists your audio serial number. It is best
to store the card in a safe place at
home. In addition, you should write the
audio system’s serial number in this
owner’s manual.
If you make a mistake entering the
code, do not start over; complete the
five-digit sequence, then enter the
correct code. You have ten tries to
enter the correct code. If you are
unsuccessful in ten attempts, you must
then leave the system on for one hour
before trying again.The system will retain your AM and
FM presets even if power is
disconnected.
NOTE:
If you have a My Acura account, it is
easy to retrieve the anti-theft code
online without having to access the
serial number.
U.S. ownersWe recommend that you register the
security code at My Acura (myacura.
com.) If you lose the Anti-theft
Identification Card before registering
the code at My Acura, you must obtain
the code from your dealer or

you will need the audio system’s serial
number. If you do not have the serial
number with you, ask your dealer or go
to
https://radionavicode.acura.com/
for
information on how to retrieve it.

Radio Theft Protection308

The security system helps to protect
your vehicle and valuables from
theft. The horn sounds and a
combination of headlights, position
lights, side marker lights and
taillights flashes if someone attempts
to break into your vehicle or remove
the audio unit. This alarm continues
for two minutes, then the system
resets. To deactivate the system
before the two minutes have elapsed,
unlock the driver's door with the key
or the remote transmitter.
The security system automatically
sets 15 seconds after you lock the
doors, hood, and tailgate. For the
system to activate, you must lock the
doors from the outside with the key,
or use driver's lock tab, door lock
master switch, or remote transmitter.
The security system indicator on the
instrument panel starts blinking
immediately to show you the system
is setting itself.
Once the security system sets,
opening any door, tailgate, or hood
without using the key or the remote
transmitter, will cause the alarm to
activate. It also activates if the
ignition switch is turned to the ON
(II) position, the audio unit is
removed from the dashboard or the
wiring is cut.The security system does not set if
any door, the tailgate, or hood is not
fully closed. Before you leave the
vehicle, make sure the doors, tailgate
and hood are securely closed.
To see if the system sets after you
exit the vehicle, press the LOCK
button on the remote transmitter
within five seconds. If the system is
set, the horn will beep once.
Do not attempt to alter this system or
add other devices to it.

Features

The HomeLink
®Universal
Transceiver built into your vehicle can
be programmed to operate up to three
remote controlled devices around
your home, such as garage doors,
lighting, or home security systems.
General Safety InformationBefore programming your HomeLink
to operate a garage door opener,
confirm that the opener has an
external entrapment protection
system, such as an‘‘electronic eye,’’or
other safety and reverse stop features.
If your garage door was manufactured
before April 1, 1982, you may not be
able to program HomeLink to operate
it. These units do not have safety
features that cause the motor to stop
and reverse it if an obstacle is
detected during closing, increasing
the risk of injury. Do not use
HomeLink with any garage door
opener that lacks safety stop and
reverse features.Units manufactured between April 1,
1982 and January 1, 1993 may be
equipped with safety stop and reverse
features. If your unit does not have an
external entrapment protection
system, an easy test to confirm the
function and performance of the safety
stop and reverse feature is to lay a 2
╳4 under the closing door. The door
should stop and reverse upon
contacting the piece of wood.
As an additional safety feature, garage
door openers manufactured after
January 1, 1993 are required to have
external entrapment protection
systems, such as an electronic eye,
which detect an object obstructing the
door.
Important Safety PrecautionsRefer to the safety information that came
with your garage door opener to test that
the safety features are functioning
properly. If you do not have this
information, contact the manufacturer of
the equipment.
Before programming HomeLink to a
garage door or gate opener, make sure
that people and objects are out of the way
of the device to prevent potential injury or
damage.
When programming a garage door opener,
park just outside the garage.Training HomeLinkBefore you begin
－If you just
received your vehicle and have not
trained any of the buttons in
HomeLink before, you should erase
any previously learned codes before
training the first button.
To do this, press and hold the two
outside buttons on the HomeLink
transceiver for about 20 seconds,
until the red indicator flashes.
Release the buttons, then proceed to
step 1.

Service Station Procedures426

Carrying Cargo in the Passenger
Compartment●
Store or secure all items that could
be thrown around and hurt
someone during a crash.
●
Be sure items placed on the floor
behind the front seats cannot roll
underneath and interfere with the
proper operation of the seats, the
sensors under the seats, or the
driver's ability to operate the
pedals.
Also, keep all cargo below the
bottom of the windows. If it is
higher, it could interfere with the
proper operation of the side
curtain airbags.
●
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.Carrying Cargo in the Cargo Area
or on a Roof Rack
●
Distribute cargo evenly on the
floor of the cargo area, placing the
heaviest items on the bottom and
as far forward as possible. Tie
down items that could be thrown
about the vehicle during a crash or
sudden stop.
●
If you fold down the second or
third row seats, tie down items that
could be thrown about the vehicle
during a crash or sudden stop.
●
If you carry large items that
prevent you from closing the
tailgate, exhaust gas can enter the
passenger area. To avoid the
possibility ofcarbon monoxide
poisoning,follow the instructions
on page 61.
●
If you carry any items on a roof
rack, be sure the total weight of
the rack and the items does not
exceed 165 lbs (75 kg).
Carrying Cargo436

Optional Separation Net
The separation net can be used to
hold back soft, lightweight items
stored in the cargo area. Heavy items
should be tied down, as the net may
not prevent them from being thrown
about the vehicle in a crash or a
sudden stop.
Optional Cargo Cover
The cargo cover can be used to cover
the cargo area behind the third row
seats. When the third row seats are
folded down, the cargo cover can be
extended over the larger area. Do not
install the cover over the larger area
if the third row seats are not folded
down.Cargo Hooks
The four hooks on the side panels
can be used to install a net for
securing items. Each hook is
designed to hold up to 50 lbs (23 kg)
of weight.
Your vehicle also has a grocery hook
on each side panel in the cargo area.
They are designed to hold light
items. Heavy objects may damage
the hook. Make sure any items put
on each hook weigh less than 6.5 lbs
(3 kg).
