2012 Acura RDX engine

Refueling1. Park with the driver's side closestto the service station pump.
2. Open the fuel fill door by pulling on the handle at the outside of the
driver's seat.
Gasoline is highly flammable
and explosive. You can be
burned or seriously injured
when handling fuel.●Stop the engine, and keep
heat, sparks, and flame
away.●Handle fuel only outdoors.●Wipe up spills immediately.
3. Remove the fuel fill cap slowly.You may hear a hissing sound as
pressure inside the tank equalizes.
Place the cap in the holder on the
fuel fill door.
4. Stop filling the tank after the fuel nozzle automatically clicks off. Do
not try to ‘‘top off ’’the tank. This
leaves some room in the fuel tank
for the fuel to expand with
temperature changes.
If the fuel nozzle keeps clicking off
even though the tank is not full,
there may be a problem with your
vehicle's fuel vapor recovery
system. The system helps keep
fuel vapor from going into the
atmosphere. Try filling at another
pump. If this does not fix the
problem, consult your dealer.

5. Screw the fuel fill cap back on untilit clicks at least once. If you do not
properly tighten the cap, you will
see a ‘‘TIGHTEN FUEL CAP ’’
message on the multi-information
display (see right column on this
page), and the malfunction
indicator lamp may also come on
(see page 466).
6. Push the fuel fill door closed until it latches. Tighten Fuel Cap Message
If your fuel fill cap is loose or
missing, a
‘‘TIGHTEN FUEL CAP ’’
message appears on the multi-
information display after you start the
engine. Turn the engine off, and confirm the
fuel fill 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 off after 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 malfunction indicator
lamp (MIL) comes on. If the fuel fill
cap was not already tightened, turn
the engine off, and check or
retighten the fuel fill 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 off,
have your vehicle inspected by a
dealer. For more information, see
page 466.

To close the hood, lift it up slightly to
remove the support rod from the
hole. Put the support rod back into
its holding clip. Lower the hood to
about a foot (30 cm) above the
fender, then let it drop. Make sure it
is securely latched.Oil Check
Park the vehicle on a level surface.
Wait a few minutes after turning the
engine off before you check the oil.
1. Remove the dipstick (orange loop).
2. Wipe off the dipstick with a clean
cloth or paper towel.
3. Hold the dipstick with a clean cloth or paper towel, and then
insert it all the way back in its
hole.
Make sure the ‘‘UP ’’mark on the
loop is facing up when you insert
the dipstick.
4. 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 Adding Engine Oil on page 420.

Engine Coolant CheckLook 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, seeAdding
Engine Coolant on page 424 for
information on adding the proper
coolant. Refer to
Owner's Maintenance
Checks on page 417 for information
about checking other items on your
vehicle. Actual Mileage and EPA Fuel
Economy Estimates Comparison.
Fuel economy is not a fixed number.
It varies based on driving conditions,
driving habits and vehicle condition.
Therefore, it is not possible for one
set of estimates to predict fuel
economy precisely for all drivers in
all environments.
The EPA fuel economy estimates
shown in the example to the right are
a useful tool for comparison when
buying a vehicle. EPA estimates
include:
City MPG
－Represents urban
driving in a vehicle in light traffic. A
range of miles per gallon achieved is
also provided.
Highway MPG －Represents a
mixture of rural and interstate
driving, in a warmed-up vehicle,
typical of longer trips in free-flowing
traffic. A range of miles per gallon
achieved is also provided.

Combined Fuel Economy－
Represents a combination of city and
highway driving. The scale
represents the range of combined
fuel economy for other vehicles in
the class. Estimated Annual Fuel Cost
－
Provides an estimated annual fuel
cost, based on 15,000 miles (20,000
km) per year multiplied by the cost
per gallon (based on EPA fuel cost
data) divided by the combined fuel
economy.

economy ratings and factors that
affect fuel economy, visit

Fuel Economy FactorsThe following factors can lower your
vehicle's fuel economy:●Aggressive driving (hard
acceleration and braking)●Excessive idling, accelerating and
braking in stop-and-go traffic●Cold engine operation (engines are
more efficient when warmed up)●Driving with a heavy load or the air
conditioner running●Improperly inflated tires

Improving Fuel EconomyVehicle MaintenanceA properly maintained vehicle
maximizes fuel economy. Poor
maintenance can significantly reduce
fuel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
information display (seeOwner's
Maintenance Checks on page 417).
For example:●Use the required engine oil (see
page 420).●Maintain proper tire inflation －
An underinflated tire increases
‘‘ rolling resistance, ’’which reduces
fuel economy.●Avoid carrying excess weight in
your vehicle －It puts a heavier
load on the engine, increasing fuel
consumption.
●Keep your vehicle clean －In
particular, a build-up of snow or
mud on your vehicle's underside
adds weight and rolling resistance.
Frequent cleaning helps your fuel
economy.
Drive Efficiently●Drive moderately －Rapid
acceleration, abrupt cornering, and
hard braking increase fuel
consumption.●Observe the speed limit －
Aerodynamic drag has a big effect
on fuel 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.

●Always drive in the highest gear
possible－If your vehicle has a
manual transmission, you can
boost your fuel economy by up
shifting as early as possible.●Avoid excessive idling －Idling
results in 0 miles per gallon (0 kms
per liter).
●Minimize the use of the air
conditioning system －The A/C
puts an extra load on the engine
which makes it use more fuel. Use
the fresh-air ventilation when
possible.●Plan and combine trips －
Combine several short trips into
one. A warmed-up engine is more
fuel efficient than a cold one. Calculating Fuel Economy
Measuring TechniquesDirect calculation is the
recommended source of information
about your actual fuel economy.
Using frequency of fill-ups or taking
fuel gauge readings are NOT
accurate measures of fuel economy.
Fuel economy may improve over the
first several thousand miles.
