2009 Acura MDX Owner's Manual

Check the condition of the battery
monthly by looking at the test
indicator window:Green －Good condition
White －Liquid level low, replace
battery
Black －Charging necessary Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent further
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (－ ) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
If the radio fuse is removed, the
audio system will disable itself. The
next time you turn on the radio you
will see ‘‘ENTER CODE ’’in the
frequency display. Use the preset
buttons to enter the digit code (see
page235).

If you need to park your vehicle for
an extended period (more than 1
month), there are several things you
should do to prepare it for storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.●Fill the fuel tank.●Wash and dry the exterior
completely.●Clean the interior. Make sure the
carpeting, floor mats, etc., are
completely dry.●Leave the parking brake off. Put
the transmission in Park.
●Block the rear wheels.●If the vehicle is to be stored for a
longer period, it should be
supported on jackstands so the
tires are off the ground.●Leave one window open slightly (if
the vehicle is being stored
indoors).●Disconnect the battery.●Support the front and rear wiper
blade arms with a folded towel or
rag so they do not touch the
windshield.●To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehicle body wax to the painted
surfaces that mate with the door
and tailgate seals.
●Cover the vehicle with a
‘‘breathable’’ cover, one made from
a porous material such as cotton.
Non-porous materials, such as
plastic sheeting, trap moisture,
which can damage the paint.●If possible, periodically run the
engine until it reaches full
operating temperature (the cooling
fans cycle on and off twice).
Preferably, do this once a month.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or
replaced, and put it back on your
vehicle as soon as you can.
Check the inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa, 4.2 kgf/cm
2)
Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution while
driving.
●Do not mount snow chains on a
compact spare.●Do not use your compact spare tire
on another vehicle unless it is the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘ CHECK TPMS SYSTEM’’
message on the multi-information
display (see page354).
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed for mounting a regular tire.INDICATOR LOCATION MARK

If you have a flat tire while driving,
stop in a safe place to change it.
Drive slowly along the shoulder until
you get to an exit or an area to stop
that is far away from the traffic lanes.
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack.
1. Park the vehicle on firm, level, and non-slippery ground. Put the
transmission in Park. Apply the
parking brake.
