2007 Acura MDX cooling

This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (hot) mark, pull
safely to the side of the road. For instru
ctions and precautions on
checking the engine’s cooling
system, see page . This shows how much f uel you
have. It may show slightly more
or less than the actual amount.

When you press a fan control button,
the fan is taken out of AUTO mode.
Wh en the indicator in the dual
button is on, the driver’s side and
passenger’s side temperature can be
controlled independently (see page
).
When the indicator in the rear
button is on, the temperature of the
rear passenger compartment can be
controlled independently (see page
).
When you set the temperature to its
lower limit ( ) or its upper limit
( ), the system runs at f ull
cooling or heating only. It does not
regulate the interior temperature.
When you press this button, the
indicator in the button comes on, and
the temperature of the rear
passenger compartment can be
adjusted separately with the
temperature control buttons on the
back of the center console. With the
indicator off, the temperature of the
rear passenger compartment is
synchronized to the driver’s side set
temperature. You will see the AUTO
SYNC on the system display of the
rear control panel. Changing the
temperature of the rear passenger
compartment also makes the
indicator to turn on, and takes the
system out of synchronized mode.

In the Auto mode, the vehicle’s
interior temperature is
independently regulated f or the
driver, f ront passenger, and rear passengers according to each
adjusted temperature. The system
also regulates each temperature
basedontheinformationof thesun
light sensor and the sun position
which is updated automatically by
the navigation’s global positioning
system (GPS). For example, if the
driver’s side of the vehicle getting to
much sun, the system will adjust to a
lower temperature.
You can set the temperatures for the
driver’s side and the passenger’s side
separately when this button is
pressed (indicator is on). When the
indicator in the DUAL button is of f ,
the temperatures for both sides are
synchronized to the driver’s side set
temperature. When def rost mode is
selected, dual mode operation is
canceled.

Your vehicle tires and spare are in
good condition and properly
inflated.
When
preparing to tow, and before
driving away, be sure to check the
following: The trailer tires and spare are in
good condition and inflated as
recommended by the trailer
maker.
The
vehicle has been properly
serviced, and the brakes,
suspension, cooling system, and
lights are in good operating
condition.
The trailer has been properly
serviced and is in good condition.
All weights and loads are within
limits.
Thehitch,safetychains,andany
other attachments are secure.
Allitemsonandinthetrailerare
properly secured and cannot shift

added weight, length, and
height of a trailer will affect your
vehicl e’s handling and performance,
so driving with a trailer requires
some special driving skills and
techniques.

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks. Always use Honda Long-Lif e
Antif reeze/Coolant Type 2. This
coolant is pre-mixed with 50 %
antif reeze and 50 % water. Never add
straight antif reeze or plain water.
If Honda Long-lif e antif reeze/
coolant is not available, you may use
another major-brand non-silicate
coolant as a temporary replacement.
Make sure it is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda Long-lif e antif reeze/coolant
as soon as possible.

Make sure the engine and radiator
are cool.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pour the coolant slowly and
caref ully so you do not spill any.
Clean up any spill immediately; it
could damage components in the
engine compartment.
Put the radiator cap back on, and
tighten it fully.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down. Remove the radiator cap cover. Remove the radiator cap by
pushing down and turning
counterclockwise.

Pour coolant into the reserve tank.
Fill it to half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components. Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.
If the washer f luid is low, a
‘‘WASHER FLUID LOW’’ message
appears on the multi-inf ormation
display.
Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition them.

Do not use engine antif reeze or a
vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield

If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or 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 f uel tank.
Change the engine oil and f ilter.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
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 f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom 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 f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.

If the temperatu re gauge stays at
the red mark, turn off the engine.
Look for any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see
on page ). Start
the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the filler neck. If you do
not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and
refilled with the proper mixture as
soon as you can.
Put the radiator cap back on
tightl y. Run the engine, and check
the temperatu re gauge. If it goes
back to the red mark, the engine
needs repair (see on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.
