2008 Acura MDX fuel

Screw the fuel fill 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 ).
Push the f uel f ill door closed until
it latches.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

Fuel economy is not a f ixed number.
It varies based on driving conditions,
driving habits and vehicle condition.
Theref ore, it is not possible f or one
set of estimates to predict f uel
economy precisely f or all drivers in
all environments.
Provides an estimated annual f uel
cost, based on 15,000 miles (20,000
km) per year multiplied by the cost
pergallon(basedonEPAfuelcost

Aggressive driving (hard

braking in stop-and-go traf f ic
Cold engine operation (engines

Driving with a heavy load or the
air conditioner running
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: 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.
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.

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
one. A warmed-up engine is more
f uel ef f icient than a cold one.
Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.
Using f requency of f ill-ups or taking

accurate measures of f uel economy.

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 in the first
column on page .
Independent of the maintenance messages in the multi-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 if they are noisy. 389
If you drive in dusty conditions, replace every 15,000
miles (24,000 km).
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).
If you drive regularly in very high temperatures
(over 110°F, 43°C), in very low temperatures
(under 20°F, 29°C), or towing a trailer, replace every
60,000 miles (U.S.)/100,000 km (Canada).
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).

To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced. Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly.
Even though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it immediately with a tire gauge.
Thetirepressuremonitoringsystem
(TPMS) warns you when a tire
pressure is low. See page f or
more inf ormation. Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.
