cooling Acura TSX 2007 Owner's Manual

This shows how much fuel you
have. It may show slightly more
or less than the actual amount.
The needle returns to the
bottom after you turn off the
ignition.
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, such as
very hot weather or a long period of
uphill driving, the pointer may rise to
the upper zone. If it reaches the red (Hot) mark, pull saf ely to the side of
the road. See page f or
instructions and precautions on
checking the engine’s cooling
system.

Proper
use of the climate control
system can make the interior dry
and comfortable, and keep the
windows clear for best visibility.
For the climate control system to
provide heating and cooling, the
engine must be running.
You can adjust the temperatures of
thedriver’ssideandthepassenger’s
side independently (see page ). The automatic climate control
system adjusts the f an speed and
airflow levels to maintain the interior
temperature you select.
Press the AUTO button. You will
see AUTO in the display.
The climate control system f or your
vehicle can also be operated using
the voice control system. See the
NavigationsectioninyourQuick
Start Guide f or an overview of this
system and the Navigation System
manual f or complete details.
Set the desired temperature by
pushing or on the driver’s
side temperature control bar. The
selected temperature will show in

In AU TO mode, the vehicle’s interior
temperature is independently
regulated for the driver and
passenger. If the driver’s side of the
vehicle is getting too much sun, the
system will adjust to a lower
temperature.
Press the AUTO button. The
indicator in the button comes on. When
you push the passenger’s side
temperature control bar, the
indicator in the DUAL button comes
on and the driver’s side and
passenger’s side temperature can be
controlled independently (see page ).
The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your pref erence.
When you set the temperature to its
lowest limit ( ) or its highest
limit ( ), the system runs at
f ull cooling or heating only. It does
not regulate the interior temperature.
In cold weather, the fan will not
come on automatically until the
heater starts to develop warm air. You can manually select various
f unctions of the climate control
system when it is in the AUTO mode.
All other f eatures remain
automatically controlled.

ways drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; then turn the wheel to the left
to get the trailer to move to the left,
andturnthewheelrighttomovethe
trailer to the right.
Follow all normal precautions when
parking, including firmly setting the
parking brake and putting the
transmission in Park (automatic) or
in first or reverse (manual). Also,
place wheel chocks at each of the
trailer’s tires.
Your
vehicle tires and spare are
properly inflated (see page ),
and the trailer tires and spare are
inflated as recommended by the
trailer maker.
Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
The
vehicle has been properly
serviced, and the suspension,
cooling system, and lights are in
good operating condition.
All weights and loads are within
limits (see pages and ).

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. If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
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 antif reeze/coolant as soon as
possible. 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.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

Make sure the engine and radiator
are cool.
Remove the radiator cap by
pushing down and turning
counterclockwise. Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down.The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
Pourthecoolantslowlyand
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.
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.
Check the reservoir’s f luid level by
removing the cap and looking at the
level gauge attached to the cap.

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 wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.
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.

carpeting, floor mats, etc., are
completely dry. Leave the parking brake off. Put
the transmission in reverse
(manual) or Park (automatic).
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.

Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off. Put
the radiator cap back on
tightly. Run the engine, and check
the temperature 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.
Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘ ’’). Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.
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
temperature gauge or lower
bef ore checking the radiator.
