2011 HONDA CIVIC fuel

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-

Bef ore you begin driving your
vehicle, you should know what
gasoline to use and how to check the
levels of important f luids. You also
need to know how to properly store
luggage or packages. The

Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Avoid full-throttle starts and rapid
acceleration.
Avoidhardbrakingforthefirst
200 miles (300 km).
Do not change the oil until the
scheduled maintenance time. Your vehicle is designed to operate
on unleaded gasoline with a pump
octane number of 87 or higher. Use
of a lower octane gasoline can cause
a persistent, heavy, metallic rapping
noise that can lead to engine damage.
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane number of 91 or higher.
Useof aloweroctanegasolinecan
cause occasional metallic knocking
noises in the engine and will result in
decreased engine perf ormance. Use
of a gasoline with a pump octane
number less than 87 can lead to
engine damage.
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Do not tow a trailer.
We recommend using quality
gasolines containing detergent
additives that help prevent fuel
system and engine deposits. In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contact
your authorized dealer f or service.
Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10% ethanol by
volume and up to 15% MTBE by
volume. Do not use gasoline
containing methanol.

If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
You may hear a knocking noise from
the engine if you drive the vehicle at
low engine speed (below about 1,000
rpm) in a higher gear. To stop this,
raise the engine speed by shif ting to
a lower gear.

Aggressive driving (hard

Cold engine operation (engines

Driving with a heavy load or the

Improperly inf lated tires
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 economy 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 (0 kms
per liter).
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.
