2007 Acura RL cooling

The automatic climate control
system adjusts the f an speed and
airflow levels to maintain the interior
temperature you select.
In AUTO mode, the vehicle’s interior
temperature is independently
regulated f or 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.
Set the desired temperature with
the temperature control bars.
You will see AUTO in the display
if theclimatemodeisselected. 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
lower or its upper limit, the system
runs at f ull cooling or heating only. It
does not regulate the interior
temperature.
When you change the f an speed, the
f an is taken out of AUTO mode and
starts to run at the selected speed.
You can manually select various
f unctions of the climate control
system when it is in f ully automatic
mode. All other f eatures remain
automatically controlled. Making any
manual selection causes the word
AUTO in the display to go out.
Press the OFF button. However, a
lack of airf low can cause the
windowstofogup.Youshouldkeep
the fan on at all times so stale air and
moisture do not build up in the
interior and cause f ogging.

Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.
Askyourtrailersalesorrental
agency if any other items are
recommended or required f or your
towing situation.When preparing to tow, and bef ore
driving away, be sure to check the
f ollowing:
The vehicle has been properly
serviced, and the tires, brakes,
suspension, cooling system, and
lights are in good operating
condition.
All items in or on the trailer are
properly secured and cannot shif t
while you drive. Thehitch,safetychains,andany
other attachments are secure. All weights and loads are within
limits. The trailer has been properly
serviced and is in good condition,
and the lights and brakes on the
trailer are working properly. Your vehicle tires and spare are

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 the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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 Anti-
f reeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.

The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise. 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.
Pourthecoolantslowlyandcarefully
so you do not spill any. Clean up any
spill immediately; it could damage
components in the engine
compartment. 3.

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 you do not find 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, before check-
ing the radiator. 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.
Start the engine, and set the
interior temperature to maximum
(climate control to FULL 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.
