2004 Acura TL coolant temperature

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. Turn to
page f or instructions and
precautions on checking the engine’s
cooling system.
This shows how much f uel you have.
It may show slightly more or less
than the actual amount. The needle
returns to the bottom after you turn
of f the ignition.240

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging
the catalytic converter.

When you select , the system
automatically switches to Fresh Air
mode and turns on the A/C.
Thedriver’ssidemodeand
passenger’s side mode can be
selected separately when the dual
button is pressed. However, whenis selected on the driver’s
side, mode selection on the
passenger’s side is not possible. The f low-through ventilation system
draws in outside air, circulates it
through the interior, then exhausts it
through vents near the rear window.
Set the temperature to maximum.
Make sure the A/C is of f .
Select and Fresh Air mode.
Set the f an to the desired speed.
The heater uses engine coolant to
warm the air. If the engine is cold, it
will be several minutes bef ore you
f eel warm air coming f rom the
system. Select and Fresh Air mode.
Set the f an to the desired speed.
Adjust the warmth of the air with
the temperature control buttons. Air conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page
). If it moves near the red zone,
turn of f the A/C until the gauge
reads normally.
Turn on the A/C by pressing the
button. The indicator in the button
comesonwhenafanspeedis
selected.
Make sure the temperature is set
to maximum heat.
Select .
If the outside air is humid, select
Recirculation mode. If the outside
air is dry, select Fresh Air mode.
Set the f an to the desired speed. you can
cool it down more rapidly by partially
opening the windows, turning on the
A/C, and setting the fan to
maximum speed in Fresh Air mode.
When is selected, the
passenger’s temperature cannot be
set separately f rom the driver’s.
You can set the temperatures and
modes f or the driver’s side and the
passenger’s side separately when
this button is pressed (indicator on).
When the indicator in the DUAL

Independent of the maintenance messages in the Multi-Information
Display, replace the brake fluid every 3 years.
If the message ‘‘SERVICE DUE NOW’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty, the first column,
page .
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 if they are noisy.

Maintenance Main Items
Replace engine oil
Replace engine oil and oil filter
Rotate tires
Inspect front and rear brakes
Check parking brake adjustment
Visually inspect these items: Tie rod ends, steering gear box, and boots
Suspension components
Driveshaft boots
Brake hoses and line (including ABS)
All fluid levels and condition of fluids
Exhaust system
Fuel lines and connections Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive primarily in dusty conditions, replace
every 15,000 miles (24,000 km).
Replace dust and pollen filter If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and
from diesel-powered vehicles, replace every 15,000
miles (24,000 km).
Inspect drive belt
Replace transmission fluid Driving in mountainous areas at very low vehicle
speeds results in higher transmission temperatures.
This requires transmission fluid changes more
frequently than recommended by the Maintenance
Minder. If you regulary drive your vehicle under these
conditions, have the transmission fluid changed at
60,000 miles (100,000 km), then every 30,000 miles
(48,000 km).
Replace spark plugs
Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), or in very low temperatures (under-20°F,
29°C), replace every 60,000 mile (U.S.)/100,000 km
(Canada)
Inspect valve clearance

If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park, and set the parking brake.
Turn of f all accessories, and turn
on the hazard warning indicators.
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
The pointer of the vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
If the temperature gauge stays at
the red mark, turn of f the engine.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (see
on page ).

NOTICE: Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature
gauge pointer at the red mark can
cause serious damage to your engine.

Start the engine and set the
interior temperature to maximum.
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 watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon 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.
Using gloves or 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.
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
(see
on
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. 8. 9.

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.
