2012 Acura TL check engine

Your vehicle still has normal f ront-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.
If the SH-AWD indicator begins to
blink while driving, it indicates the
dif f erential temperature is too high.
You will also see an ‘‘SH-AWD DIFF
TEMP. HIGH’’ message on the
multi-inf ormation display.
If this happens, pull to the side of the
road when it is safe, park the vehicle
and shift to Park (automatic), and let the engine idle until the indicator
goes out. If the indicator does not go
out, take your vehicle to a dealer to
have it checked.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘CHECK SH-AWD SYSTEM’’
message also appears on the multi-
inf ormation display, there is a
problem with the SH-AWD system.

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.
If your vehicle has an automatic
transmission, set the parking
brake before you put the
transmission in Park. This keeps
the vehicle from moving and
putting pressure on the parking
mechanism in the transmission.Make sure the moonroof and the
windows are closed.
Turn of f the lights.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Lock the doors.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire. Check the indicator on the
instrument panel to verif y that the
security system is set.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb. If your vehicle has a manual
transmission, put it in f irst gear.If the vehicle is f acing downhill,
turn the front wheels toward the
curb. If your vehicle has a manual
transmission, put it in reverse gear.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
If you are unable to stop the
engine normally when the vehicle is
parked(intheParkpositiononthe

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 surfaces. It does this by
regulating the engine’s output, and
by selectively applying the brakes.
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 is off, the VSA OFF
indicator comes on as a reminder.
When VSA activates, you will see the
VSA system indicator blink.
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 system indicator blink. 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 this indicator comes on while
driving, you will also see a ‘‘CHECK
VSA SYSTEM’’ and/or ‘‘CHECK
HILL START ASSIST SYSTEM’’
message on the multi-inf ormation
display. Drive cautiously as the VSA
may not be f unctioning. Without
VSA, your vehicle will have normal
braking and cornering ability, but it
will not have VSA traction and
stability enhancement. Also, the VSA
OFF switch will not operate. 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, have the VSA system inspected by
your dealer.
If there is a problem with the hill
start assist system, the VSA system
indicator comes on and stays on. The
multi-inf ormation display shows a
‘‘CHECK HILL START ASSIST
SYSTEM’’ message.
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

Hillstartassistmaynotpreventyour
vehicle f rom rolling downhill on a
very steep or slippery slope, and will
not operate on small inclines.
Hill start assist is not a replacement
f or the parking brake. If parking
your vehicle, ensure that the
transmission is in park, and/or the
parking brake is f ully applied bef ore
exiting the vehicle. For vehicles with
manual transmission, it is
recommended that you turn of f the
engine bef ore exiting the vehicle.If the VSA system indicator comes
on with a ‘‘CHECK HILL START
ASSIST SYSTEM’’ message on the
multi-inf ormation display, there may
be a problem with the hill start assist.
The VSA also may not f unction.
Have your vehicle inspected by your
dealer.
Hill start assist will still operate even
when VSA is switched off.
On manual transmission models:
You must come to a complete stop,
press the clutch pedal, and shif t to
f irst gear when f acing uphill, or
reverse when f acing downhill.
Release the brake pedal. The brakes
remain engaged brief ly to keep the
vehicle f rom rolling f orward or
backward while you move your f oot
f rom the brake pedal to the
accelerator pedal. Gently apply the
accelerator pedal while
simultaneously releasing the clutch
pedal, as in normal driving. Hill start
assist will release brake pressure
gradually as you accelerate.
Hill start assist will also hold braking
brief ly if you select the neutral gear
position with the clutch pedal
depressed when f acing uphill.

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 significantly underinflated.
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
information placard.
Each tire has its own pressure
sensor (not including the spare tire).
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

Î
Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inflation pressure as
specified on the vehicle placard and
in the owner’s manual (see).
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 underinf lated
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
thetiresareoverinflated.
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-inf ormation
display (see page ). Toselectthetirepressuremonitor,
press the INFO button several times
with the ignition switch in the ON
(II) position or with the power mode
ON.
You will see the above display on the
multi-inf ormation display when each
tire pressure is normal.
