This indicator should come on when
the ignition switch is ON (II), and go
out af ter the engine starts. If it
comes on brightly when the engine
is running, it indicates that the
charging system has stopped
charging the battery.By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged
to keep the engine running. Drive to
a service station or garage where
you can get technical assistance.
Immediately turn of f all electrical
accessories:radio,heater,A/C,
climate control, rear def ogger, cruise
control, etc. Try not to use other
electrically-operated controls such as
the power windows. Keep the engine
running and take extra care not to
stall it. Starting the engine will
discharge the battery rapidly.

However, if the brake pedal does not
f eel normal, you should take
immediate action. Because of the
brake system’s dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will f eel the brake pedal
go down much f arther bef ore the
vehicle begins to slow down, and you
will have to press harder on the
pedal. The distance needed to stop
will be much longer. If it comes on at any other time, it
indicates a problem with the vehicle’s
brake system. In most cases, the
problem is a low f luid level in the
brake f luid reservoir. Press lightly on
the brake pedal to see if it f eels
normal. If it does, check the brake
f luid level the next time you stop at a
service station (see page ). If the
f luid level is low, take the vehicle to
your dealer and have the brake
system inspected f or leaks or worn
brake pads.Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the
longer distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible. (See
on page .)
If you must drive the vehicle a short
distance in this condition, drive
slowly and cautiously.
The Brake System Indicator comes
on when you turn the ignition ON
(II). If the parking brake is not set, it
goes of f af ter you start the engine. If
the parking brake is set, it goes of f
when you f ully release the parking
brake with the engine running. 319

If your vehicle needs to be towed,
call a prof essional towing service or,
if youbelongtoone,anorganization
that provides roadside assistance.
Never tow your vehicle behind
another vehicle with just a rope or
chain. It is very dangerous.
There are three popular types of
prof essional towing equipment.
The operator
loads your vehicle on the back of a
truck. Any other
method of towing will damage the
drive system. When you contact the
towing agency, inf orm them that a
f lat-bed is required. The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. Refer to
on page
for non-emergency towing
inf ormation.
The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
cables lif t that end of the vehicle of f
the ground. Your vehicle’s
suspension and body can be
seriously damaged. 283Flat -bed Equipment

Towing a MDX with only two tires on
the ground will damage parts of the
4WD system. It should be transported
on a f lat-bed truck or trailer.

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.

Some conventional gasolines are
being blended with alcohol or an
ether compound. These gasolines
are collectively ref erred to as
oxygenated f uels. To meet clean air
standards, some areas of the United
States and Canada use oxygenated
f uels to help reduce emissions.
If you use an oxygenated f uel, be
sure it is unleaded and meets the
minimum octane rating requirement.
Bef ore using an oxygenated f uel, try
to conf irm the f uel’s contents. Some
states/provinces require this
informationtobepostedonthe
pump.The f ollowing are the U.S. EPA and
Canadian CGSB approved
percentages of oxygenates:
(Methyl Tertiary Butyl
Ether)
You may use gasoline containing up
to 15 percent MTBE by volume. (ethyl or grain alcohol)
You may use gasoline containing up
to 10 percent ethanol by volume.
Gasoline containing ethanol may be
marketed under the name ‘‘Gasohol.’’
(methyl or wood
alcohol)
Your vehicle was not designed to use
fuel that contains methanol.
Methanol can corrode metal parts in
the fuel system, and also damage
plastic and rubber components. This
damage would not be covered by
your warranties. If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or perf ormance
problems resulting f rom the use of
an oxygenated f uel containing more
than the percentages of oxygenates
given above are not covered under
warranty.
