2012 Acura MDX ECO mode

Check the air pressures when the
tires are cold. This means the vehicle
has been parked for at least 3 hours,
or driven less than 1 mile (1.6 km).
Add or release air, if needed, to
match the recommended cold tire
pressures.
If you check air pressures when the
tires are hot [driven for several miles
(kilometers)], you will see readings 4
to 6 psi (30 to 40 kPa, 0.3 to 0.4
kgf/cm
2) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinflated.
While tubeless tires have some
ability to self-seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure.You should get your own tire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier for you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.

recommended cold tire pressures for
most normal driving conditions.

High Speed Driving
We strongly recommend that you do
not drive faster than the posted
speed limits and conditions allow. If
you ever drive in a sanctioned
competitive event at sustained high
speeds (over 99 mph or 160 km/h),
be sure to adjust the cold tire
pressures as shown below. If you do
not, excessive heat can build up and
cause sudden tire failure.MDX, Technology Package, and U.S.

Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:●
Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.
●
Cuts, splits, or cracks in the side of
the tire. Replace the tire if you can
see fabric or cord.
●
Excessive tread wear.
Tires542

It is best to replace all four tires at
the same time. If that is not possible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle's handling.
If you ever replace a wheel, make
sure that the wheel's specifications
match those of the original wheels.
Also be sure you use only TPMS
specific wheels. If you do not, the tire
pressure monitoring system will not
work.
Replacement wheels are available at
your dealer.
Installing improper tires on your
vehicle can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner's manual.

Winter Driving
Tires marked‘‘M＋S’’or‘‘All
Season’’on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best performance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.
