2008 Acura RDX fuel

If the f uel nozzle keeps clicking of f
even though the tank is not f ull,
there may be a problem with your
vehicle’s fuel vapor recovery
system. The system helps keep
f uel vapor f rom going into the
atmosphere. Try f illing at another
pump. If this does not f ix the
problem, consult your dealer.
Stop f illing the tank af ter the f uel
nozzle automatically clicks of f . Do
not try to ‘‘top off’’ the tank. Leave
some room f or the f uel to expand
with temperature changes.
Remove the f uel f ill cap slowly.
You may hear a hissing sound as
pressure inside the tank escapes.
Place the cap in the holder on the
fuel fill door.Screw the f uel f ill cap back on
until it clicks at least once. If you
do not properly tighten the cap,
you will see a ‘‘TIGHTEN FUEL
CAP’’ message on the multi-
inf ormation display (see right
column on this page), and the
malf unction indicator lamp may
also come on (see page ).
If your f uel f ill cap is loose or
missing, a ‘‘TIGHTEN FUEL CAP’’
message appears on the multi-
information display after you start
the engine.
Push the f uel f ill door closed until
it latches.

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. When you can restart the
engine, the message appears again.
The message goes of f af ter several
days of normal driving once you
tighten or replace the fuel fill cap. To
scroll to another message, press the
INFO ( / ) button.
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 . Park the vehicle, and set the
parking brake. Pull the hood
release handle located under the
lower lef t corner of the dashboard.
The hood will pop up slightly.
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.

Fuel economy is not a f ixed number.

economy precisely f or all drivers in

Provides an estimated annual f uel
cost, based on 15,000 miles (20,000
km) per year multiplied by the cost

Aggressive driving (hard

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 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.
‘‘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.

Fill the f uel tank until the nozzle automatically clicks of f .
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

f uel ef f icient than a cold one.
Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.

items at the specif ied intervals. If
you are unsure of how to perf orm
any check, turn to the appropriate
page listed.
Engine oil level Check every
time you fill the fuel tank. See
page .
Engine coolant level Check the
radiator reserve tank every time
you f ill the f uel tank. See page .
Automatic transmission Check
the f luid level monthly. See page . Brakes Check the f luid level
monthly. See page .
Tires Check the tire pressure
monthly. Examine the tread f or
wear and foreign objects. See page
.
Lights Check the operation of
the headlights, parking lights,
taillights, high-mount brake light,
and license plate lights monthly.
See page .
According to state and federal
regulations, f ailure to perf orm
maintenance on the items marked

: Maintenance Main Items
Replace engine oil
Replace engine oil and oil filter
Inspect front and rear brakes
Check parking brake adjustment
Inspect these items: Tie rod ends, steering gear box, and boots
Suspension components
Driveshaft boots
Brake hoses and lines (including ABS)
All fluid levels and condition of fluids
Exhaust system
Fuel lines and connections Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive in dusty conditions, replace
every 15,000 miles (24,000 km).
Replace dust and pollen filter If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and
from diesel-powered vehicles, replace every 15,000
miles (24,000 km).
Inspect drive belt
Replace transmission and transfer fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher
transmission and transfer temperatures. This
requires transmission and transfer fluid changes
more frequently than recommended by the
maintenance minder. If you regularly drive your
vehicle under these conditions, have the transmission
and transfer fluid changed at 60,000 miles
(100,000 km), then every 30,000 miles (48,000 km).
Replace spark plugs
Inspect valve clearance
Replace engine coolant
Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000 km), then every 15,000 miles (24,000 km).

If the message ‘‘SERVICE DUE NOW’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty on page.
Independent of the maintenance items in the information display, replace
the brake fluid every 3 years.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 only if they are noisy.
