If you need to park your vehicle f or
an extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.Fill the f uel tank.
Change the engine oil and f ilter.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
Leave the parking brake off. Put
the transmission in Park. Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
If you store your vehicle f or 12
months or longer, have your Acura
dealer perf orm the inspections called
f or in the 24 months/30,000 miles
(48,000 km) maintenance schedule
(Normal Conditions) as soon as you
take it out of storage (see page ).
The replacements called f or in the
maintenance schedule are not
needed unless the vehicle has
actually reached that time or mileage. 199

If you have a f lat tire while driving,
stop in a saf e place to change it.
Drive slowly along the shoulder until
you get to an exit or an area to stop
that is far away from the traffic lanes.Park the vehicle on f irm, level, and
non-slippery ground. Put the
transmission in Park. Apply the
parking brake.Turn on the hazard warning lights,
and turn the ignition switch to
LOCK (0). Have all the
passengers get out of the vehicle
while you change the tire.

TOOLS SPARE TIRE
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack.

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things: Check the transmission interlock.
The transmission must be in Park
orNeutralorthestarterwillnot
operate.
Turn the ignition switch to ON (II).
Turn on the headlights, and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See
on page .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereis
probably something wrong with
the electrical circuit f or the
ignition switch or starter motor.
You will need a qualif ied
technician to determine the
problem (see
on page ). If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
f rom a booster battery (see page
).
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run. Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the dash panel to blink
rapidly(seepage ).

Are you using the proper starting
procedure? Ref er to
on page .
Do you have f uel? Check the f uel
gauge; the warning indicator may
not be working.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page . Although this seems like a simple
procedure, you should take several
precautions.
To jump start your vehicle:
You cannot start your Acura by
pushing or pulling it. Open the hood, and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or like ice, do not try
jump starting until it thaws.
Turn of f all the electrical acces-
sories: heater, A/C, climate
control, audio system, lights, etc.
Put the transmission in Neutral or
Park, and set the parking brake.
Connect one jumper cable to the
positive ( ) terminal on your
Acura’s battery. Connect the other
end to the positive ( ) terminal
on the booster battery.

NOTICE:
A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery. If a battery sits in extreme
cold, the electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

The brake system indicator
normally comes on when
you turn the ignition switch
to ON (II), and as a
reminder to check the
parking brake. It will stay
on if you do not f ully
release the parking brake.
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
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. However, if the brake pedal does not
f eel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design 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.
If your vehicle needs to be towed,
call a professional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
The operator will load
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 a f lat-bed is required.
Refer to on page
for non-emergency towing
inf ormation.
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 long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible.
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
