2006 Acura TL ignition

In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run.Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).
Are you using the proper starting
procedure? Ref er to on page . There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See
on page .
Do you have f uel? Check the f uel
gauge; the warning indicator may
not be working.

If your vehicle battery has been
disconnected or gone dead, these
codes are erased. It takes at least
three days of normal driving to set
the codes again.
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.To check if they are set, turn the
ignition switch to the ON (II)
position, 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 for a state
emissions test until the readiness
codes are set. Ref er to
for more
inf ormation (see page ).
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 takes several days of
normal driving.

If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed and repaired as
soon as possible (seeon page ).
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 ON (II), and as a
reminder to check the
parking brake. It will stay
on if you do not f ully
release the parking brake.
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.
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
If 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. If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

µµThe operator
loads your vehicle on the back of a
truck.
The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground.
If , due to damage, your vehicle must
be towed with the f ront wheels on
the ground, do this: Release the parking brake.
Shif t the transmission to neutral.
If your vehicle is equipped with a
f ront spoiler, remove it bef ore
towing so it is not damaged.
If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
behind another vehicle with just a
rope or chain. It is very dangerous.

With the f ront wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h). If you decide to tow your vehicle
with all f our wheels on the ground,
make sure you use a properly-
designed and attached tow bar.
Prepare the vehicle for towing as
described above, and leave the
ignition switched in the
ACCESSORY (I) position so the
steering wheel does not lock. Make
sure the radio and any items plugged
into the accessory power socket are
turned of f so they do not run down
the battery.

Trying to lif t or tow your vehicle by the
bumpers will cause serious damage.
The bumpers are not designed to
support the vehicle’s weight.
Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shif t the transmission or start the
engine (automatic transmission), your
vehicle must be transported with the
f ront wheels of f the ground.

For very short distances, such as
f reeing the vehicle, you can use the
detachable towing hook that mounts
on the anchor in the f ront bumper. If your vehicle gets stuck in sand,
mud, or snow, call a towing service
to pull it out (see page ).
To use the towing hook:Remove the cover f rom the bumper by pushing the lower part
of the cover with your f inger.
Remove the towing hook, hook
extension, and wheel nut wrench
f rom the tool case in the spare tire.
Using the wheel nut wrench,
fasten the extension into the bolt
hole.

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These f our systems work
together to control the engine’s
combustion and minimize the
amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.The emissions control systems are
designed and certif ied to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor. The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned. This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The PGM-FI system uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel control. The
powertrain control module (PCM) in
automatic transmission vehicles or
the engine control module (ECM) in
manual transmission vehicles uses
various sensors to determine how
much air is going into the engine. It then controls how much f uel to inject
under all operating conditions.
