2003 Acura MDX warning

If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading
(climbing a long, steep hill on a
hot day with the A/C running, for
example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving. Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn of f the heating and cooling/
climate control system and all
otheraccessories.Turnonthe
hazard warning indicators.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until all are
disconnected. Otherwise, you may
cause an electrical short.
The pointer of your vehicle’s
temperature gauge should stay in
the midrange under most conditions.
Itmaygohigherif youaredrivingup
a long steep hill on a very hot day. If
it climbs to the red mark, you should
determine the reason. Your vehicle can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
In either case, you should take
immediate action.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.

This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. It should
never come on when the engine is
running. If it starts f lashing, it
indicates that the oil pressure
dropped very low f or a moment, then
recovered. If the indicator stays on
with the engine running, it shows
that the engine has lost oil pressure
and serious engine damage is
possible. In either case, you should
take immediate action.Saf ely pull of f the road and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ). Let the vehicle sit f or a minute.
Open the hood and check the oil
level (see page ). Although oil
levelandoilpressurearenot
directly connected, an engine that
is very low on oil can lose pressure
during cornering and other driving
maneuvers.Start the engine and watch the oil
pressure indicator. If the light
does not go out within ten seconds,
turn of f the engine. There is a
mechanical problem that needs to
be repaired bef ore you can
continue driving. (See
on page .)

µ
The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate. The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
Quality grades can be f ound where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example:
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades. Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.

The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specif ied indoor
laboratory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire f ailure. The
grade C corresponds to a level of
perf ormance which all passenger car
tires must meet under the Federal
Motor Vehicle Saf ety Standard No.
109. Grades B and A represent
higher levels of perf ormance on the
laboratory test wheel than the
minimum required by law. Warning: The temperature grade f or
this tire is established f or a tire that
is properly inf lated and not over-
loaded. Excessive speed, underinf la-
tion, or excessive loading, either
separately or in combination, can
cause heat buildup and possible tire
f ailure.
