2009 Acura TL check engine

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 emergency
brake assist system increases the
stopping f orce when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, reduces their ef f ectiveness and
reduces brake pad lif e. In addition,
f uel economy can be reduced. 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 taking your f oot of f the
accelerator and downshif ting to a
lower gear.
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. Be extra
cautious and alert in your driving.
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.
All f our brakes have audible brake
wear indicators.

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surf aces. It does this
by regulating the engine’s output,
and by selectively applying the
brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise f rom the VSA
hydraulic system. You will also see
the VSA activation indicator blink.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety. When VSA activates, you will see the
VSA activation indicator blink.
If this indicator comes on while
driving, pull to the side of the road
when it is saf e, and turn of f the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
If the indicator does not come on
when the ignition switch is turned
to the ON (II) position, there may be
a problem with the VSA system.
Have your dealer inspect your
vehicle as soon as possible.
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 .
When the VSA system indicator
comes on, you will also see a
‘‘CHECK VSA SYSTEM’’ message
on the multi-information display. The main f unction of the
VSA system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control f unction.
With the VSA system indicator on,
you may not be able to stop the
engine even if you park the vehicle
saf ely. To stop the engine, see on page

VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.
Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
This switch is under the driver’s side
vent. To turn the VSA system on and
of f , press and hold it until you hear a
beep.
When VSA is off, the VSA activation
indicator comes on as a reminder.
Press and hold the switch again. It
turns the system back on.
If the low tire pressure/TPMS
indicator comes on (see page ),
or the multi-information display
shows a ‘‘CHECK TPMS SYSTEM’’
message with the indicator flashing
(see page ), the VSA system
automatically turns on even if the
VSA system is turned off with the
VSA OFF switch. In this case, you
cannot turn the VSA system of f by
pressing the VSA OFF switch again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.

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.If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure shown on the driver’s
doorjamb.
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
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.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.
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
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message. It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible. 583

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 on page .
Independent of the maintenance messages on 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 service 3 if they are noisy.

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
Replace transmission and transfer fluid
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).
Inspect valve clearance
Replace engine coolant
Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds results in higher level of mechanical (shear)
stress to fluid. This requires differential fluid changes
more frequently than recommended by the
maintenance minder. If you regularly drive your
vehicle under these conditions, have the differential
fluid changed at 7,500 miles (12,000 km), then every
15,000 miles (24,000 km).
