2011 HONDA CIVIC SEDAN ignition

If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have your vehicle
checked by the dealer as soon as
possible.
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.
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. If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
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
‘‘CHECK FUEL CAP’’ message on
the inf ormation display. Tighten the
cap until it clicks at least once.
Tightening the cap will not turn the
indicator of f immediately; it can take
several days of normal driving. 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.

more information (see page ).

damage your vehicle’s emissions

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 (seeon page ).
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully. If the ABS indicator comes on with
the brake system indicator, have
your vehicle inspected by your
dealer immediately.
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. It will stay
on if you do not f ully release the
parking brake.
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 ).
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. 300

If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
The operator
loads your vehicle on the back of a
truck. Therearetwowaystotowyour
vehicle: 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.
Leave the ignition switch in the
ACCESSORY (I) position so the
steering wheel does not lock.
The tow
truck uses two pivoting arms that go
under the f ront tires and lif t them of f
the ground. The rear tires remain on
the ground. With the f ront wheels on the ground,
do not tow the vehicle more than 50
miles (80 km), and keep the speed
below35mph(55km/h).
Start the engine.
Release the parking brake. Shif t to the D position and hold f or
5 seconds, then to N.
Turn of f the engine.

Do not tie down the vehicle at an
angle that would allow the towing
cables to contact the vehicle’s f ront
bumper. To avoid possible damage,
protect the f ront bumper with tape.
If your vehicle is equipped with a
f ront spoiler, remove it bef ore

The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in the ACCESSORY (I)
position, and make sure the steering
wheel turns f reely bef ore you begin
towing.
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.

The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda 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 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.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust emissions controls
includethreeorfoursystems:
PGM-FI, ignition timing control,
exhaust gas recirculation, and three
way catalytic converter. These
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 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.
