ignition ACURA RL 2012 Owners Manual

When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the f uses. If the f uses
areOK,thereisprobably
something wrong with the
electrical circuit f or the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. See
on page . Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:
Check these things:
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page . Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate. Make sure the remote is with you,
inside the vehicle.
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of the
battery and terminal connections
(see page ). You can then try
jump starting the vehicle from a
booster battery (see page ). You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run. You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.

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 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 .
Are you using a properly coded
built-in key or remote? An
improperly coded built-in key or
remote will cause the immobilizer
system indicator in the instrument
panel to blink rapidly (see page
).
Do you have f uel? Check the f uel
gauge; the low f uel indicator may
not be working.Although this seems like a simple
procedure, you should take several
precautions.
You cannot start your vehicle by
pushing or pulling it. 401521 512

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 you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘TIGHTEN FUEL CAP’’ message on
the multi-information display.
Tighten the cap until it clicks at least
once (see page ). Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving.If the battery in your vehicle has
been disconnected or gone dead,
thesecodesmaybeerased.Itcan
take several days of driving under
various conditions to set the codes
again.
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 f or an emissions
test until the readiness codes are set.
Refer to for
more inf ormation (see page ). If this indicator comes on
while driving, or if you see
a ‘‘CHECK EMISSION SYSTEM’’
message on the multi-inf ormation
display, 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. The malf unction indicator lamp may
also come on with the ‘‘D’’ indicator.

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.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 (see
on page ). 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.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display. If the brake system indicator comes
on while driving, the brake f luid level
is probably low. You will see a
‘‘BRAKE FLUID LOW’’ message on
the multi-information display. Press
lightly on the brake pedal to see if it
f eels normal. If it does, check the
brake f luid level the next time you
stop at a service 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. If you do
not release the parking brake, the
indicator will stay on, and you will
see a ‘‘RELEASE PARKING
BRAKE’’ message on the multi-
inf ormation display.

Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f . If something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pages
, , and , or the diagram
on the f use box lid, which f use or
f uses control that device. Check
those fuses first, but check all the
f uses bef ore deciding that a blown
f use is the cause. Replace any blown
f uses, and check if the device works.
Check each of the large f uses in
the under-hood f use box by
looking through the top at the wire

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 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)
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.This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
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.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
quality parts may increase the
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 inf orma-
tion. The three way catalytic converters
are in the exhaust system. Through
chemical reactions, they convert HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.

Then drive in city/suburban
traffic for at least 10 minutes.
When traf f ic conditions allow, let
the vehicle coast f or several
seconds without using the
accelerator pedal or the brake
pedal.
Stop the vehicle, turn of f the
ignition switch, and leave it of f f or
30 minutes.
If the testing f acility determines the
readiness codes are still not set, see
your dealer. Select a nearby lightly traveled
major highway where you can
maintain a speed of 50 to 60 mph
f or at least 20 minutes. Drive on
the highway in D. Do not use the
cruise control. When traf f ic allows,
drive f or 90 seconds without
moving the accelerator pedal.
(Vehicle speed may vary slightly;
this is okay.) If you cannot do this
f or a continuous 90 seconds
because of traf f ic conditions, drive
f or at least 30 seconds, then repeat
it two more times (f or a total of 90
seconds). 7. 8.
