2007 Acura MDX Owner's Manual

Check each of the large fuses in
the primary under-hood fuse box
by looking through the top at the
wire inside. Removing these fuses
requires a Phillips-head
screwdriver.
If
something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pages , , and , or the diagram
on the f use box lid, which f use or
f uses control that device. Check
those fuses first, but check all the
f uses bef ore deciding that a blown
f use is the cause. Replace any blown
f uses, and check if the device works.
Remove the cover f rom the f use
box. Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f . 3.

If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.
Look f or a burned wire inside the
f use. If it is burned out, replace it
withoneof thesparefusesof the
same rating or lower.
Check the smaller f uses in the
under-hood f use boxes and rear
f use box, and all the f uses in the
interior f use box by pulling out
each one with the f use puller
provided in the primary under-
hood f use box. 5.

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem with your
vehicle. Leave the blown fuse in
that circuit, and have your vehicle
checked by a qualified technician. If
the radio fuse is removed, the
audio system will disable itsel f. The

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.

Your vehicle has several identif ying
numbers located in various places.
The vehicle identif ication number
(VIN) is the 17-digit number your
dealer uses to register your vehicle
f or warranty purposes. It is also
necessary f or licensing and insuring
your vehicle. The easiest place to
find the VIN is on a plate fastened to
the top of the dashboard. You can
seeitbylookingthroughthe
windshield on the driver’s side. It is
also on the certification label
attached to the driver’s doorjamb,
and is stamped on the engine
compartment bulkhead. The VIN is
also provided in bar code on the
certif ication label.
