2008 Acura RL check engine

Park the vehicle, and set the
parking brake. Pull the hood
release lever located under the
lower lef t corner of the dashboard.
The hood will pop up slightly.
Your vehicle’s on board 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 ‘‘TIGHTEN FUEL CAP’’ message
appears on the multi-inf ormation
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 of f af ter several days of
normal driving once you tighten or replace the f uel f ill cap. To scroll to
another message, press the INFO
button. The ‘‘TIGHTEN 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
the 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

Remove the dipstick again, and
check the level. It should be
between the upper and lower
marks.
If it is near or below the lower
mark, see on
page .
Wait a f ew minutes af ter turning the
engine of f bef ore you check the oil.
Remove the dipstick (orange loop).
Wipe the dipstick with a clean
cloth or paper towel.
Insert the dipstick all the way back
into its hole. 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, see
on page .
Refer to on page f or inf ormation

Aggressive driving (hard

Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines

up)
Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
An under-inf 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.
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 multi-
inf ormation display (see
on page ).
For example: Idling
results in 0 miles per gallon. If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
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.
Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.

Reset trip counter to zero.
Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
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.
Fuel economy may improve over the
f irst several thousand miles. 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.
