2008 Acura TL check engine

Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.
Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you. The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrumental panel and the
appropriate tire position indicator on
thetirepressuremonitoronthe
multi-inf ormation display (see page)tocomeon. When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
The multi-inf ormation display also
shows a ‘‘CHECK TIRE PRESSURE’’
message (see page ). You should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure as indicated on the
vehicle’s tire inf ormation placard.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly. For example, if you check and f ill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure/
TPMS indicator to come on. Or, if
youcheckandadjustyourtire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tire may become overinf lated.
However, the low tire pressure/
TPMS indicator will not come on if
the tires are overinflated.
Refer to page for tire inflation
guidelines.
If there is a problem with the TPMS,
this indicator begins to f lash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a ‘‘CHECK TPMS SYSTEM’’
message on the multi-information
display (see page ).

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 in the first column
on page .
Independent of the maintenance messages in the multi-information
display, replace the brake fluid every 3 years.
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.

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 (under20°F, 29°C), replace every 60,000 miles (U.S.)/
100,000 km (Canada).

Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements.
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Install the engine oil
f ill cap, and tighten it securely. Wait
a f ew minutes, and recheck the oil
level (see page ). Do not f ill
above the upper mark; you could
damage the engine. Honda motor oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Honda motor oil in your vehicle f or
optimum engine protection. Make
sure the API certif ication seal says
‘‘For Gasoline Engines.’’
The oil viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your vehicle to
improve cold weather starting and
f uel economy.

Let the engine run f or several
minutes, then check the drain bolt
and oil f ilter f or leaks.
Reinstall the engine oil f ill cap.
Start the engine. The oil pressure
indicator should go out within 5
seconds. If it does not, turn of f the
engine and check your work.
Install a new oil f ilter according to
the instructions that come with it.
Remove the oil f ilter, and let the
remaining oil drain. A special
wrench (available from your
dealer) is required. Turn of f the engine and let it sit
f or several minutes, then check
the oil level on the dipstick. If
necessary, add more oil.
Make sure the oil f ilter gasket is
not stuck to the engine block. If it
is, remove it bef ore installing a
new oil f ilter. Make sure to clean of f any dirt
and dust on the connecting
surf ace of a new oil f ilter.
Put a new washer on the drain bolt,
then reinstall the drain bolt.

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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. 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.
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.

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