The condition of your vehicle and
your driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your vehicle accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your vehicle uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cto
cut down on air conditioning use.
Use the f low-through ventilation
when the outside air temperature is
moderate.
In winter, the build-up of snow on
your vehicle’s underside adds weight
and rolling resistance. Frequent
cleaning helps your f uel mileage and
reduces the chance of corrosion. An important part of that mainte-
nance is the (see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly. 305

Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don’t, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.
When towing a trailer, we
recommend that you carry a f ull-size
spare wheel and tire f or your vehicle.
Using the compact spare that came
with the MDX may adversely affect
vehicle handling.
We also recommend that you carry a
f ull-size spare wheel and tire f or your
trailer. Ask your trailer sales or
rental agency where and how to
store the spare. See page f or proper tire size,
page f or how to store a f ull-sized
wheel and tire, and page for
inf ormation on changing a f lat tire.
Remember to unhitch the trailer
bef ore changing a f lat.When preparing to tow, and bef ore
driving away, be sure to check the
f ollowing:
The vehicle has been properly
serviced, and the brakes,
suspension, and cooling system
are in good operating condition. If
you tow f requently, f ollow the
Severe Conditions maintenance
schedule. The lights and brakes on your
vehicle and the trailer are working
properly.
Your vehicle tires and spare are in
good condition and properly
inf lated (see page ).
The trailer tires and spare are in
good condition and inf lated as
recommended by the trailer
maker.
Allitemsonandinthetrailerare
properly secured and cannot shif t
while you drive. Thehitch,safetychains,andany
other attachments are secure. All weights and loads are within
limits (see pages and ). The trailer has been properly
serviced and is in good condition.

The f ollowing pages contain practical
tips on basic of f -highway operation.
Driving of f -highway can be hard on a
vehicle. Bef ore you leave the
pavement, be sure all scheduled
maintenance and service has been
done, and that you have inspected
your vehicle. Pay special attention to
the condition of the tires, and use a
gauge to check the tire pressures.Of f -highway, the general rule is to
keep your speed low. Of course,
you’ll need enough speed to keep
moving forward. But at higher
speeds, you have less time to assess
conditions and make good decisions.
There’s also a greater chance of
sliding if you brake or turn too
quickly on wet soil, gravel, or ice. In
any situation, never go f aster than
conditions allow.Generally, the best of f -pavement
braking technique is to gently
depress the brake pedal, then
increase pressure as more braking is
needed. Avoid hard braking. Keep in
mind that you will usually need more
time and distance to brake to a stop
on unpaved surf aces.
After you return to the pavement,
caref ully inspect your vehicle to
make sure there is no damage that
could make driving it unsaf e. Check
the tires for damage and for proper
pressure. If you need to brake hard because of
an emergency, apply steady, even
pressure to the brake pedal. Do not
pump the brakes; let the anti-lock
braking system pump them f or you.
If you pump the brakes, the anti-lock
cannot work as ef f iciently, and your
stopping distance may be increased.
Forbettertractiononallsurfaces,
accelerate slowly and gradually build
up speed. If you try to start too fast
on wet soil, mud, snow, or ice, you
might not have enough traction to
get underway. You may even dig
yourself into a hole. Starting with the
shif t lever in second gear (2) will
help get you to a smooth start on
snow and ice.

Maintenance
Maint enance293

Regularly maintaining your vehicle is
the best way to protect your
investment. Proper maintenance is
essential to your saf ety and the
saf ety of your passengers. It will also
reward you with more economical,
trouble-f ree driving, and help reduce
air pollution.Some of the most important saf ety
precautions are given here. However,
we cannot warn you of every
conceivable hazard that can arise in
perf orming maintenance. Only you
can decide whether or not you
should perf orm a given task.
This section includes instructions f or
simple maintenance tasks, such as
checking and adding oil. Any service
items not detailed in this section
should be perf ormed by an Acura
technician or other qualif ied
mechanic.

Failure to properly follow
maintenance instructions and
precautions can cause you to
be seriously hurt or killed.
Always follow the procedures
and precautions in this owner’s
manual.
Improperly maintaining this
vehicle or failing to correct a
problem before driving can
cause a crash in which you can
be seriously hurt or killed.
Always follow the inspection
and maintenance
recommendations and
schedules in this owner’s
manual.

Bef ore you begin any maintenance,
make sure your vehicle is parked on
level ground and that the parking
brake is set. Also, be sure the engine
is of f . This will help to eliminate
several potential hazards:Be sure
there is adequate ventilation
whenever you operate the engine.
Let the
engine and exhaust system cool
bef ore touching any parts. Read the instructions before you
begin, and make sure you have the
tools and skills required.
To reduce the possibility of f ire or
explosion, be caref ul when working
around gasoline or batteries. Use a
commercially available degreaser or
parts cleaner, not gasoline, to clean
parts. Keep cigarettes, sparks, and
flames away from the battery and all
f uel-related parts.
Do
not run the engine unless in-
structed to do so. You should wear eye protection and
protective clothing when working
near the battery or when using
compressed air.

The Maintenance Schedule specif ies
how of ten you should have your
vehicle serviced and what things
need attention. It is essential that
you have your vehicle serviced as
scheduled to retain its high level of
saf ety, dependability, and emissions
control perf ormance.Service your vehicle according to the
time and mileage periods on one of
the Maintenance Schedules on the
f ollowing pages. Select the schedule
f or ‘‘Severe Conditions’’ if most of
your driving is done under one or
more of the conditions listed on that
page. Otherwise, f ollow the schedule
f or ‘‘Normal Conditions.’’
The services and time or distance
intervals shown in the maintenance
schedule assume you will use your
vehicle as normal transportation f or
passengers and their possessions.
You should also f ollow these
recommendations:
Avoid exceeding your vehicle’s
load limit. This puts excess stress
on the engine, brakes, and many
other parts of your vehicle. The
load limit is shown on the tire
inf ormation label on the driver’s
doorjamb. Operate your vehicle on
reasonable roads within the legal
speed limit.
Drive your vehicle regularly over a
distance of several miles
(kilometers).
Always use unleaded gasoline with
theproperoctanerating(seepage
