2003 Acura MDX tire pressure

You’ll f ind many saf ety
recommendations throughout this
section, and throughout this manual.
Therecommendationsonthispage
are the ones we consider to be the
most important.Excessive speed is a major f actor in
crash injuries and deaths. Generally,
the higher the speed the greater the
risk, but serious accidents can also
occur at lower speeds. Never drive
f aster than is saf e f or current
conditions, regardless of the
maximum speed posted.
While airbags can save lives, they
can cause serious or fatal injuries to
occupants who sit too close to them,
or are not properly restrained.
Inf ants, young children, and short
adults are at the greatest risk. Be
sure to f ollow all instructions and
warnings in this manual. (See page
.)
Having a tire blowout or a
mechanical f ailure can be extremely
hazardous. To reduce the possibility
of such problems, check your tire
pressures and condition f requently,
and perform all regularly scheduled
maintenance. (See page .)
Children are saf est when they are

one drink can reduce your ability to
respond to changing conditions, and
your reaction time gets worse with
every additional drink. So don’t drink
and drive, and don’t let your f riends
drink and drive, either.
A seat belt is your best protection in
all types of collisions. Airbags
supplement seat belts, but airbags
are designed to inf late only in a
moderate to severe f rontal collision.
So even though your vehicle is
equipped with airbags, make sure
you and your passengers always
wear your seat belts, and wear them
properly. (See page .)

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

one of the f ollowing:
Press the VTM-4 Lock button.
Move the shift lever to D , D or
D.
Turn the ignition to OFF (0).
When you restart your MDX, the
VTM-4 Lock f eature will be of f .
The VTM-4 Lock will temporarily
disengage when the vehicle speed
exceeds 18 mph (30 km/h). It will
automatically engage again as the
speed slows below 18 mph (30
km/h). The light in the VTM-4 Lock
button will remain on the whole time.
The vehicle speed must be below
18 mph (30 km/h).
Move the shift lever to first (1),
second (2) or reverse (R) gear. To
shif t Reverse f rom Neutral, come
to a complete stop and then shift.
Press the VTM-4 Lock button.
The light in the button will come
on.
To get unstuck, apply light pressure
to the accelerator pedal. Do not spin
the f ront tires f or more than a f ew
seconds. Because of the amount of
torque applied to the rear tires, they
should not spin. This is normal. If
you are not able to get the vehicle to
move, apply the brakes to stop the
wheels, then reverse direction. 1.

Do not continuously spin the f ront tires
of your MDX. Continuously spinning
the f ront tires can cause transmission
or rear dif f erential damage.

You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal; it is the ABS rapidly
pumping the brakes.this defeats the
purpose of the ABS. Let the ABS
work f or you by always keeping f irm,
steady pressure on the brake pedal
as you steer away from the hazard.
This is sometimes ref erred to as
Activation varies with the amount of
traction your tires have. On dry
pavement, you will need to press on
thebrakepedalveryhardbeforeyou
activate the ABS. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
Your vehicle has an Anti-lock Brake
System (ABS) as standard
equipment. ABS helps to prevent the
wheels f rom locking up and skidding
during hard braking, allowing you to
retain steering control.
When the f ront tires skid, you lose
steering control; the vehicle
continues straight ahead even
though you turn the steering wheel.
The ABS helps to prevent lock-up
and helps you retain steering control
by pumping the brakes rapidly; much
f aster than a person can do it.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
The ABS also balances the f ront-to
rear braking distribution according
to vehicle loading.

f requently f or wear and proper
pressure. Both are important in
preventing ‘‘hydroplaning’’ (loss of
traction on a wet surface). In the
winter, mount snow tires on all f our
wheels f or the best handling.
Watch road conditions caref ully,
they can change f rom moment to
moment. Wet leaves can be as slip-
pery as ice. ‘‘Clear’’ roads can have
patches of ice. Driving conditions
can be very hazardous when the
outside temperature is near f reezing.
The road surf ace can become
covered with areas of water puddles
mixed with areas of ice, so your
traction can change without warning.
Be caref ul when downshif ting. If
traction is low, you can lock up the
drive wheels f or a moment and cause
askid. Be very cautious when passing, or
beingpassedbyothervehicles.The
spray f rom large vehicles reduces
your visibility, and the wind buf f eting
can cause you to lose control.

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.
