2003 Acura TL check engine

A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
The condition of your car and your
driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your car according
to the maintenance schedule. This
will keep it in top operating condition.
An important part of that mainte-
nance is the
(see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly.
In winter, the build-up of snow on
your car’s underside adds weight and
rolling resistance. Frequent cleaning
helps your f uel mileage and reduces
thechanceof corrosion. The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cor
set the climate control to a higher
temperature to cut down on air
conditioning use. Use the f low-
through ventilation when the outside
air temperature is moderate.

Put your f oot on the brake pedal only
when you intend to brake. Resting
your f oot on the pedal keeps the
brakes applied lightly, causing them
to build up heat. Heat build-up can
reduce how well your brakes work. It
also keeps your brake lights on all
the time, conf using drivers behind
you.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 downshif ting to a lower
gear and taking your f oot of f the
accelerator pedal.
Check your brakes af ter 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. Since a
longer distance is needed to stop
with wet brakes, be extra cautious
and alert in your driving.
Your Acura 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 ABS helps
you retain steering control when
braking very hard.
All f our brakes have audible brake
wear indicators.
When the brake pads need replacing,
you will hear a distinctive metallic
‘‘screeching’’ sound when you apply
the brakes. If you do not have the
brake pads replaced, they will begin
screeching all the time.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not conf use this with the
brakewearindicators.Theymakea
