tires Acura MDX 2004 User Guide

Before you leave the pavement, be
sure to do all scheduled maintenance
and service and that you inspect your
vehicle. Pay special attention to the
condition of the tires and check the
tire pressure.
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.
Recheck the condition of the tires
and the tire pressure.
The route presents limits (too steep
or bumpy roads). You have limits
(driving skill and comf ort). And your
vehicle has limits (traction, stability,
and power).
Driving of f -highway can be
hazardous if you f ail to recognize
limits and take the proper
precautions.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 and you may dig
yourself a hole. Starting with the
shif t lever in second gear (2) will
help you have a smoother start on
snow and ice.
Keep in mind that you will usually
need more time and distance to
brake to a stop on unpaved surf aces.
Avoid hard braking. Do not pump
the brakes; let the anti-lock braking
system pump them f or you.
Debris in the road can damage your
suspension or other components.
Because your vehicle has a high
center of gravity, driving over a large
obstacle, or allowing a wheel to drop
into a deep hole can cause yourvehicle to tip or roll over.
If you can’t clearly see all road
conditions or obstacles, walk the
slope bef ore you drive on it. If you
have any doubt whether or not you
can saf ely drive on the slope, don’t
do it. Find another route.
Bef ore driving through water, stop
and make sure that:
The water is not deep enough to
cover your wheel hubs, axles or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components.
If you are driving up a hill and f ind
that you cannot continue,
. Your vehicle could roll
over. Slowly back down the hill,
f ollowing the same route you took up
the hill.
do not try to
turn around

The banks are sloped so you can
drive out.
The water is not f lowing too f ast.
Deep rushing water can sweep you
downstream. Even very shallow
rushingwatercanwashthe
ground f rom under your tires and
cause you to lose traction and
possibly roll over.
The banks and surf ace under the
water provide good traction. The
water may hide hazards such as
rocks, holes, or mud.
If you decide it is saf e to drive
through water, choose a suitable
speed and engage the VTM-4 Lock.
Proceed without shif ting or changing
speeds, and do not stop the vehicle
or shut of f the engine.
After driving through water, test
your brakes. If they got wet, gently
pump them while driving slowly until
they operate normally. If the water is deeper than the wheel
hubs, some additional service may
be required. This service is not
covered by your warranties.
If you get stuck, engage the VTM-4
Lock (see page ). Caref ully try to
go in the direction (f orward or
reverse) that you think will get you
unstuck. Do not spin the tires at high
speeds. It will not help you get out
and may cause damage to the
transmission or VTM-4 system.
If you are unable to f ree yourself ,
your vehicle is equipped with f ront
and rear tow hooks designed f or this
purpose.
Use a nylon strap to attach the MDX
to the recovery vehicle and caref ully
take out the slack in the strap. Once
the strap is tight, the recovery
vehicle should apply f orce.
Remember that the recovery vehicleneeds good traction to avoid
becoming stuck, too.
You should never use a jack to try to
get unstuck. Your vehicle could
easily slip of f the jack and hurt you
or someone else.
You may be able to safely tow a
lightweight trailer (such as a
motorcycle or small tent trailer) of f -
road if you f ollow these guidelines.
Do not exceed 1,000 lbs (450 kg)
or a tongue weight of 100 lbs (45
kg).
Trytostayonsmooth,leveldirt
roads, and avoid driving in hilly
terrain.
Allow extra room f or starting,
stopping, and turning.
Slow down if you encounter bumps
or other obstacles.

Your authorized Acura dealer knows
your vehicle best and can provide
competent, ef f icient service.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done

Maintenance Schedule for Severe Conditions

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.
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.Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.
Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to f ail
f rom being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,aremore
prone to damage from road hazards,
and wear unevenly.Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose one to two psi (10 to 20 kPa, 0.1
to 0.2 kgf /cm ) per month.
Remember to check the spare tire at
thesametime.
Add or release air, if needed, to
match the recommended cold tire
pressures on page .
The Tire Pressure Monitoring
System (TPMS) will warn you when
a tire pressure is low. See page
f or inf ormation on the 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. Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km).

Inf lation
221
Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.

If you check the pressure when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to0.4
kgf /cm ) higher than the cold
reading. This is normal; do not
release air to match the cold
pressure.
Tubeless tires have some ability to
self -seal if they are punctured. You
should look closely f or punctures if a
tire starts losing pressure.
Youshouldgetyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.Thecompactsparetirepressureis:
For convenience, the recommended
tire sizes and cold air pressures are
on a label on the driver’s doorjamb.
For additional technical inf ormation
about your tires, see page .
Every time you check inf lation, you
should also examine the tires for
damage, f oreign objects, and wear.
Youshouldlookfor:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherortheseconditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord.

P235/65R17 103T 32 psi (220 kPa , 2.2 kgf/cm
)

Your vehicle’s tires have wear
indicators molded into the tread.
When the tread wears down to that
point, you will see a 1/2 inch (12.7
mm) wide band running across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread lef t on
the tire. A tire that is this worn gives
very little traction on wet roads. You
should replace the tire if you can see
the tread wear indicator in three or
more places around the tire.In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
To help increase tire lif e and
distribute wear more evenly, rotate
the tires every 7,500 miles (12,000
km). Move the tires to the positions
showninthecharteachtimethey
are rotated. If you purchase
directional tires, rotate only f ront-to-
back.
Have your dealer check the tires if
you f eel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed f rom the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comf ort and tire lif e. For best results,
have the installer perform a dynamic
balance.

It is best to replace all f our tires at

Replacing just one tire can seriously
