climate control Acura TL 2009 User Guide

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 adjust a f an control, the
f an is taken out of AUTO mode.To keep stale air and mustiness
f rom collecting, you should have
the f an running at all times.
Keep the system completely of f
f or short periods only.
To turn the system completely of f ,
press the ON/OFF button.
Each time you press this button, the
climate control system switches
between on and of f . Turning on the
system with this button selects your
last climate control selection.
You can also select the appropriate
mode on the driver’s side and the
passenger’s side separately. To
change a mode, press and release
the appropriate side mode control
button. This will take the mode
control out of AUTO mode.
In AUTO mode, the vehicle’s interior
temperature is independently
regulated f or the driver and f ront
passenger according to each
adjusted temperature. The system
also regulates each temperature
basedontheinformationof thesun
light sensor and the sun’s position which is updated automatically by
the navigation’s global positioning
system (GPS). If one side of the
vehicle is getting too much sun, the
system lowers the temperature only
on that side.
When you press this button, the
indicator in the button comes on, and
the passenger’s side temperature
and mode control is synchronized to
thedriver’ssidesettemperatureand
mode control. Changing the
passenger’s side temperature or
mode control makes the indicator go
of f and takes the system out of
SYNC mode.

When the indicator in the button is
on, air f rom the vehicle’s interior is
sent through the system again.
When the indicator is off, air is
brought in f rom the outside of the
vehicle (fresh air mode).
Switch to recirculation mode when
driving through dusty or smoky
conditions, then return to fresh air
mode.
Thesystemshouldbeleftinfresh
air mode under almost all conditions.
Keeping the system in recirculation
mode, particularly with the A/C of f ,
can cause the windows to fog up.
The outside air intakes f or the
climate control system are at the
base of the windshield. Keep this
area clear of leaves and other debris.
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. When you turn the A/C off, the
system cannot regulate the inside
temperature if you set the
temperature control below the
outside temperature.

Check the condition of the wiper
blades at least every 6 months.
Replace them if you f ind signs of
cracking in the rubber, areas that are
getting hard, or if they leave streaks
and unwiped areas when used.Raise each wiper arm of f the
windshield, lif ting the driver’s side
first, then the passenger’s side.
This f ilter removes the dust and
pollenthatisbroughtinfromthe
outside through the climate control
system.
Have your dealer replace the filter
when this service is indicated by a
maintenance message on the multi-
inf ormation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the f low f rom
theclimatecontrolsystembecomes
less than usual.
Disconnect the blade assembly
fromthewiperarmbypushingin

while you push the blade assembly
toward the base of the arm.

Although this seems like a simple
procedure, you should take several
precautions.
You cannot start a vehicle with an
automatic transmission by pushing
or pulling it.Open the hood, and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or like ice, do not try
jump starting until it thaws.
Turn of f all the electrical
accessories: climate control, audio
system, lights, etc. Put the
transmission in Park, and set the
parking brake.
Pull up the battery terminal cover
to remove. The battery terminal
cover can be removed without
removing f ront bulkhead cover.

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone

Keep all sparks, open flames,

electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(seeon
page ).
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.
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.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.

Removing the radiator cap
while the engine is hot can

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
Quality grades can be f ound where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate.
The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
