2011 Acura MDX ignition

The Immobilizer System protects
your vehicle from theft. If an
improperly coded key (or other
device) is used, the engine's fuel
system is disabled.
When you turn the ignition switch to
the ON (II) position, the immobilizer
system indicator should come on
briefly, then go off. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to the
LOCK (0) position, remove the key,
reinsert it, and turn the ignition
switch to the ON (II) position again.
The system may not recognize your
key's coding if another immobilizer
key or other metal object (i.e. key
chain) is near the ignition switch
when you insert the key.If the system repeatedly does not
recognize the coding of your key,
contact your dealer.
Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
If you have lost your key and you
cannot start the engine, contact your
dealer.
Always take the ignition key with you
whenever you leave the vehicle alone.

The ignition switch has four positions:
LOCK (0), ACCESSORY (I), ON (II),
and START (III).
LOCK (0)－You can insert or remove
the key only in this position. To turn
the key to the LOCK (0) position, the
shift lever must be in Park, and you
must push the key in slightly.
If the front wheels are turned, the anti-
theft lock may make it difficult to turn
the key. Firmly turn the steering wheel
to the left or right as you turn the key.
ACCESSORY (I) －You can operate
the audio system and the accessory
power sockets in this position.
ON (II) －This is the normal key
position when driving. Several of the
indicators on the instrument panel
come on as a test when you turn the
ignition switch from the
ACCESSORY (I) to the ON (II)
position.
START (III) －Use this position
only to start the engine. The switch
returns to the ON (II) position when
you let go of the key. You will hear a reminder beeper if
you leave the key in the ignition
switch in the LOCK (0) or the
ACCESSORY (I) position and open
the driver's door. Remove the key to
turn off the beeper.
The shift lever must be in Park

Lockout PreventionWith any door and the tailgate open
and the key in the ignition, both
master door lock switches are
disabled. They are not disabled if all
the doors and the tailgate are closed.
If you try to lock an open driver's
door by pulling the lock tab rearward
the lock tab on the driver's door pops
out.Childproof Door Locks
The childproof door locks are
designed to prevent children seated
in the rear from accidentally opening
the rear doors. Each rear door has a
lock lever near the edge. With the
lever in the LOCK position (lever is
down), the door cannot be opened
from the inside regardless of the
position of the lock tab. To open the
door, push the lock tab forward and
use the outside door handle.Tailgate
To open the tailgate, push up inside
the handle, then lift up. To close the
tailgate, use the inner handle to pull
it down, then press down on the back
edge.
Keep the tailgate closed at all times
while driving to avoid damaging the
tailgate and to prevent exhaust gas
from getting into the interior. See
Carbon Monoxide Hazard

MDX, Technology Package, and U.S.Technology Package with EntertainmentmodelsBoth front seats are equipped with
seat heaters. Because of the sensors
for the side airbag cutoff system,
there is no heater in the passenger's
seat-back. The ignition switch must
be in the ON (II) position to use the
heaters.
Push the front of the switch, HI, to
rapidly heat up the seat. After the
seat reaches a comfortable
temperature, select LO by pushing
the back of the switch. This will keep
the seat warm.

In the HI setting, the heater turns off
when the seat gets warm, and turns
back on after the seat's temperature
drops.
In the LO setting, the heater runs
continuously. It does not cycle with
temperature changes.
Follow these precautions when using
the seat heaters:●
Use the HI setting only to heat the
seats quickly, because it draws
large amounts of current from the
battery.
●
If the engine is left idling for an
extended period, do not use the
seat heaters even on the LO
setting. It can weaken the battery,
causing hard starting.
A multi-information display message
may inform you when the battery
charge is getting low. See page 82 for
more information. Seat Heaters and Seat Ventilation
If equippedBoth front seats are equipped with
seat heaters and an air ventilation
system. The passenger seat only has
heaters in the seat bottom because of
the side airbag system.
The ignition switch must be in the
ON (II) position to use the heaters
and the air ventilation system.
To use the heaters, press thebutton. The indicator (red) next to
the button will come on. There are
four settings in the heaters:
