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 557).
6. Push the fuel fill door closed until it latches. Tighten Fuel Cap Message
Your vehicle's on board diagnostic system
will detect a loose or missing fuel fill cap as
an evaporative system leak. The first time a
leak is detected a
‘‘TIGHTEN FUEL CAP’’
message appears on the multi-information
display. 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. The
message should go 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. The ‘‘TIGHTEN
FUEL CAP’’ message will appear each time
you restart the engine until the system turns
the message off.
If the system still detects a leak in
the 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 557.

Oil CheckWait 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. Insert the dipstick all the way back into its hole.
4. Remove the dipstick again, andcheck 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 511.Engine Coolant Check
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
Adding
Engine Coolant on page 514 for
information on adding the proper
coolant.
Refer to Owner's Maintenance
Checks on page 507 for information
about checking other items on your
vehicle.

Fuel Economy Factors
The 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 multi-
information display (seeOwner's
Maintenance Checks on page 507).For example:
●
Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page 511).
●
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).
Fuel Economy42410/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu

●
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
(kilometers).
Checking Your Fuel Economy1)Fill the fuel tank until the nozzle automatically clicks off.
2)Reset trip counter to zero.
3)Record the total gallons (liters) needed to refill.
4)Follow one of the simple calculations above.

If the SH-AWD indicator blinks while
driving, it indicates the differential
temperature is too high. You will also
see an‘‘SH-AWD DIFF TEMP.
HIGH ’’message on the multi-
information display. If this happens,
pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
