2012 Acura RDX key battery

You should have received a key
number tag with your keys. You will
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 from direct
sunlight, high temperature, and
high humidity.●Do not drop the keys or set heavy
objects on them.●Keep the keys away from liquids.
If they get wet, dry them
immediately with a soft cloth.
The valet key does not contain a
battery. Do not try to take it apart.
Retractable Master KeyThe master key can be retracted into
the remote transmitter. To use the
key, push the release button to
release the key from the transmitter.
The key should be fully extended. To
retract the key, push the release
button and at the same time push the
key into the remote transmitter until
it is securely latched. Always use the fully-extended key
when you insert it to the ignition
switch. If the key does not fully
extend, the immobilizer system may
not operate properly and may
prevent the engine from starting.
The key may come in contact with
your finger while being retracted or
extended. Make sure your fingers do
not touch the pivot of the key when
retracting or extending the key.RELEASE BUTTON

Your vehicle's starting system has an
auto control mode. When you turn
the ignition switch to the START (III)
position, this feature keeps the
engine's starter motor running until
the engine starts. Follow these
instructions to start the engine:1. Apply the parking brake.
2. In cold weather, turn off all electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal. 4. Without touching the accelerator
pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. The starter
motor can run for up to 9 seconds
to guarantee starting when the
outside temperature is very low.
If you hold the ignition switch in
the START (III) position for more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for up to 25
seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
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. For
more information, see page 124.The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem.
