2009 Acura TSX check engine

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.
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.
If the tire is flat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
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.
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.458Low Tire Pressure/

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.
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.
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. 392

Your vehicle has been designed
primarily to carry passengers and
their cargo. You can also use it to
tow a trailer if you caref ully observe
the load limits, use the proper
equipment, and f ollow the guidelines
in this section.
The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,000 lbs (450 kg).
Towing a load that is too heavy
can seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain.
The weight that
the tongue of a f ully-loaded trailer
puts on the hitch should be
approximately 10% of the total
trailer weight. Too much tongue
load reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable
and cause it to sway.
Avoid towing a trailer during your
vehicle’s f irst 600 miles (1,000 km)
(see page ).356

ÛÝYour authorized dealer knows your
vehicle best and can provide
competent, ef f icient service.
However, service at a dealer is not
mandatory to keep your warranties
in ef f ect. Maintenance may be done
by any qualif ied service f acility or
person who is skilled in this type of
automotive service. Keep all receipts
as proof of completion, and have the
person who does the work f ill out
your Maintenance Journal or
Canadian Maintenance Log. Check
your warranty booklet f or more
inf ormation.
We recommend using Acura parts
and fluids whenever you have
maintenance done. These are
manuf actured to the same high
quality standards as the original
components, so you can be conf ident
of their performance and durability.
If you have the required service
done but do not reset the display, or
reset the display without doing the
service, the system will not show the
proper maintenance intervals. This
canleadtoseriousmechanical
problems because you will no longer
have an accurate record of when
maintenance is needed.
Select ‘‘RESET’’ by pressing the
INFO ( / ) button, then press
the SEL/RESET button to reset
the engine oil lif e display. The
maintenance item code(s) will
disappear, and the engine oil lif e
will reset to ‘‘100.’’ If you want to
cancel the oil lif e reset mode,
select ‘‘CANCEL.’’

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

Rotate tires
Replace air cleaner element If you drive 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 or trailer towing results in higher
transmission and transfer temperatures. This
requires transmission and transfer fluid changes
more frequently than recommended by the
maintenance minder. If you regularly drive your
vehicle under these conditions, have the transmission
and transfer fluid changed at 60,000 miles (100,000
km), then every 30,000 miles (48,000 km). (For A/T

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 any. Clean up any
spills immediately. Spilled oil could
damage components in the engine
compartment.Reinstall the engine oil f ill cap, and
tighten it securely. Wait a f ew
minutes, and recheck the oil level on
the engine oil dipstick. Do not f ill
above the upper mark; you could
damage the engine.
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.
