key Acura MDX 2012 Service Manual

Headlight Aiming
The headlights were properly aimed
when your vehicle was new. If you
regularly carry heavy items in the
cargo area or pull a trailer,
readjustment may be required.
Adjustments should be done by your
dealer or another qualified
technician.
Low Beam Headlight Bulb
Replacement
The low beam headlight bulbs are a
type of high voltage discharge tube.
High voltage can remain in the
circuit even with the light switch off
and the key removed. Because of
this, you should not attempt to
examine or change a low beam
headlight bulb yourself. If a low
beam headlight bulb fails, take the
vehicle to your dealer to have it
replaced.Replacing a High Beam Headlight
Bulb
Your vehicle has halogen headlight
bulbs. When replacing a bulb, handle
it by its base, and protect the glass
from contact with your skin or hard
objects. If you touch the glass, clean
it with denatured alcohol and a clean
cloth.
Halogen headlight bulbs get very hot
when lit. Oil, perspiration, or a scratch
on the glass can cause the bulb to
overheat and shatter.
1. Open the hood.
2. Remove the front bulkhead cover
(see page 516).
(Passenger's side)
Remove the power steering
reserve tank from the stay
brackets.STAY BRACKETS

Maintenance

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:●
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
faster than normal, but the engine
does not start up and run.
Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.Check these things:
●
Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
●
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Startingon page 558.
●
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
Emergency Towingon page 572.If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal
connections (see page 547). You
can then try jump starting the
vehicle from a booster battery (see
page 558).
The Starter Operates Normally
In this case, the starter motor's speed
sounds normal, or even faster than
normal, when you turn the ignition
switch to the START (III) position,
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 instrument panel
to blink rapidly (see page 74).
