Apply the parking brake.
In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
Make sure the shif t lever is in
Park. Press on the brake pedal.
Without touching the accelerator
pedal, turn the ignition key to the
START (III) position. If the engine
does not start right away, do not
hold the key in START (III) f or
more than 15 seconds at a time.
Pause f or at least 10 seconds
bef ore trying again.
If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed half-way
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.If the engine still does not start,
press the accelerator pedal all the
way down and hold it there while
starting in order to clear f looding.
As bef ore, keep the ignition key in
the START (III) position f or no
more than 15 seconds. Return to
step 5 if the engine does not start.
If it starts, lif t your f oot of f the
accelerator pedal so the engine
does not race.
An engine is harder to start in cold
weather. The thinner air f ound at
high altitude above 8,000 f eet (2,400
meters) adds to the problem.
Use the f ollowing procedure: Turn of f all electrical accessories
to reduce the drain on the battery. Push the accelerator pedal half-
way to the f loor and hold it there
while starting the engine. Do not
hold the ignition key in START
(III) f or more than 15 seconds.
When the engine starts, release
the accelerator pedal gradually as
the engine speeds up and smooths
out.
If the engine fails to start in step 2,
push the accelerator pedal to the
f loor and hold it there while you
try to start the engine for no more
than 15 seconds. If the engine
does not start, return to step 2.

Diagnosing why your 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,thereisproba-
bly something wrong with the
electrical circuit for 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 the proper starting
procedure? Ref er to on page .

To jump start your vehicle, f ollow
these directions closely:
If your vehicle’s battery has run
down,youmaybeabletostartthe
engine by using a booster battery.
Although this seems like a simple
procedure, you should take several
precautions.
Put the transmission in Neutral or
Park, and set the parking brake. Open the hood and check the
physical condition of the battery
(see page ). 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, stereo system, lights, etc.
You cannot start your Acura by
pushing or pulling it.
Your vehicle has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly.
Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
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 . 1.

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.
