2014 Acura TL check engine

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.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. 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 (seeon page ).
Start the engine, and set the
interior temperature to maximum
heat (each temperature control
sets to ‘‘ ’’). 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.
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.

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.

Start the engine, and watch the oil
pressure indicator. If it does not go
outwithin10seconds,turnoff the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(see on page).
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ). Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers. Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning lights.
This indicator should never
come on when the engine is
running. If it starts f lashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
You will also see a ‘‘CHECK
ENGINE OIL LEVEL’’ message on
the multi-information display when
this indicator comes on.
The indicator notif ies you of low oil
pressure and does not measure the
oil level. Check your vehicle’s oil
level at each ref ueling. 2.

Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.
If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
You will also see a ‘‘CHECK
CHARGING SYSTEM’’ message on
the multi-information display.

If the indicator comes on repeatedly,
even though it may go of f as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
If this indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If the battery in your vehicle has
been disconnected or gone dead,
thesecodesmaybeerased.Ittakes
several days of driving under various
conditions to set the codes again.
If your vehicle has an automatic
transmission, the malf unction
indicator lamp may also come on
with the ‘‘D’’ indicator.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. Tighten the cap until it
clicks at least once. Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving.
You will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display.

If you keep driving with the

damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

ÎIf the f luid level is low, take your
vehicle to a dealer, and have the
brake system inspected f or leaks or
worn brake pads.
However, if the brake pedal does not
f eel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design will still give you braking at
two wheels. You will f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal. You will also see a ‘‘LOW BRAKE
FLUID’’ message on the multi-
inf ormation display.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display when this
indicator comes on.
To check if they are set, turn the
ignition switch to the ON (II)
position (set the power mode to ON,
on models with keyless access
system), without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle f or an emissions
test until the readiness codes are set.
Refer to for
more information (see page ).
Models equipped with the
keyless access system have an
engine start/stop button instead
of an ignition switch. ON Mode
is the equivalent of ON (II). For
more inf ormation, see pages
and .
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
station (see page ). The brake system indicator normally
comes on when you turn the ignition
switch to the ON (II) position, and
as a reminder to check the parking
brake. It will stay on if you do not
f ully release the parking brake. :

Removing these f uses requires a
