2009 HONDA CIVIC check engine

Your vehicle’s onboard diagnostic
system will detect a loose or missing
f uel f ill cap as an evaporative system
leak. The f irst time a leak is detected
a ‘‘CHECK FUEL CAP’’ message
appears on the information display.
Turn the engine of f , and conf irm the
f uel f ill cap is installed. If it is, loosen
it, then retighten it until it clicks at
least once. The message should go
off after several days of normal
driving once you tighten or replace
the f uel f ill cap. To scroll to another
display, press the SEL/RESET
button. The ‘‘CHECK FUEL CAP’’
message will appear each time you
restart the engine until the system
turns the message of f .If the system still detects a leak in
your vehicle’s evaporative emissions
system, the malf unction indicator
lamp (MIL) comes on. If the f uel f ill
cap was not already tightened, turn
the engine of f , and check or
retighten the f uel f ill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go of f ,
have your vehicle inspected by a
dealer. For more inf ormation, see
page .
The inf ormation display in the
instrument panel shows you the
engine oil lif e and maintenance
service items when the ignition
switch is in the ON (II) position. This
inf ormation helps to keep you aware
of the periodic maintenance your
vehicle needs f or continued trouble-
f ree driving. Ref er to page f or
more inf ormation.

This shows how much f uel you have.
It may show slightly more or less
than the actual amount.This shows the temperature of the
engine’s coolant. During normal
operation, the reading should rise to
about the middle of the gauge. In
severe driving conditions, such as
very hot weather or a long period of
uphill driving, the reading may rise
intotheupperhalfofthegauge.Ifit
reaches the red (Hot) mark, pull
safely to the side of the road. See

Avoid driving with an extremely low
f uel level. Running out of f uel could
cause the engine to misf ire, damaging

Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.
Put your f ingers under the f ront
edge of the hood near the center.
Slide your hand to the lef t until
you f eel the hood latch handle.
Push this handle up to release it.
Lif t up the hood.
If the hood latch handle moves
stif f ly, or if you can open the hood
without lifting the handle, the
mechanism should be cleaned and
lubricated. Pull the support rod out of its clip
by holding the grip, and insert the
end into the designated hole in thehood.
To close the hood, lif t it up slightly
to remove the support rod f rom
the hole. Put the support rod back
into its holding clip. Lower the
hood to about a f oot (30 cm) above
the fender, then let it drop. Make
sure it is securely latched.
Remove the dipstick (orange
handle).
Insert it all the way back in its tube.
Wipe of f the dipstick with a clean
cloth or paper towel.

Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeon page f or

coolant. Refer to

The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see
on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Idling
results in 0 miles per gallon.
An underinf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption.
In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.

Reset trip counter to zero.
Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one.
Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.
Using f requency of f ill-ups or taking
f uel gauge readings are NOT
accurate measures of f uel economy.
