If the indicator does not come on
when the ignition switch is turned to
ON(II),theremaybeaproblem
with the VSA system. Have an Acura
dealer inspect your vehicle as soon
as possible.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.This switch is under the lef t vent.
Press it to turn the Vehicle Stability
Assist system on and of f .
When VSA is off, the VSA Activation
Indicator comes on as a reminder.
Pressing the switch again turns the
system back on.VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are the same size
and type as your original tires (see
page ).
Deactivate the VSA system if you
need to drive with the compact spare
tire installed (see page ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.

One of the most convenient and
important f eatures of the Multi-
Inf ormation Display on your Acura is
the Maintenance Minder.
Based on engine operating
conditions and accumulated engine
revolutions, the onboard computer in
your Acura calculates the remaining
engine oil lif e.When the remaining engine oil lif e is
15 percent, you will see the message
‘‘SERVICE DUE SOON’’ along with
all maintenance items that are
needed at oil change time. Ref er to
page f or a complete list of the
maintenance main items and sub
items.
The system also displays the code
f or other scheduled maintenance
items needing service.
The remaining engine oil lif e is
displayed on the Multi-Inf ormation
Display as a percentage when you
turn the ignition switch to ON (II).

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

non-slippery ground. Put the
transmission in Park (automatic)
or Reverse (manual). Apply the
parking brake.
Turn on the hazard warning lights,
and turn the ignition switch to

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.
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
the f uses are OK, there is
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 ).
Check these things:
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).
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, the shif t
lever must be in Park or Neutral.

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 instrument panel
to blink rapidly (see page ).
Are you using the proper starting
procedure? Ref er to on page . There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).

To check if they are set, turn the
ignition to ON (II), without starting
the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds. If it then goes of f , the
readiness codes are set. If it blinks 5
times, the readiness codes are not
set. If possible, do not take your
vehicle f or a state emissions test
until the readiness codes are set.
Refer to State Emissions Testing for
more information (see page ).
If the indicator comes on
while driving, it means one
of the engine’s emissions
control systems may have a problem.
Even though you may f eel no
dif f erence in your vehicle’s
perf ormance, it can reduce your f uel
economy and cause increased
emissions. Continued operation may
cause serious damage.
If you have recently ref ueled your
vehicle, the indicator coming on
could be a loose or missing f uel f ill
cap. Tighten the cap until it clicks at
least three times. Tightening the cap
will not turn the indicator of f
immediately; it takes at least three
days of normal driving. If the indicator comes on repeatedly,
even though it may go of f as you
continue driving, have the vehicle
checked by the dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.If your vehicle battery has been
disconnected or gone dead, these
codes are erased. If takes at least
three days of normal driving to set
the codes again.

NOTICE:If you keep driving with the
Malf unction Indicator Lamp on, you
can damage your vehicle’s emission
controls and the engine. Those repairs
may not be covered by your vehicle’s
warranties.

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 (seeon page ).
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 ). The brake system indicator
normally comes on when
you turns 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.
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 you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully. If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by an Acura dealer
immediately.
If the f luid level is low, take your
vehicle to a dealer and have the
brake system inspected f or leaks or
worn brake pads. 211

If your vehicle is equipped with a
f ront spoiler, remove it bef ore
towing so it is not damaged. With the f ront wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).If you decide to tow your vehicle
with all f our wheels on the ground,
make sure you use a properly-
designed and attached tow bar.
Prepare the vehicle for towing as
described previously, and leave the
ignition switch in the ACCESSORY
(I) position so the steering wheel
does not lock. Make sure the radio
and any items plugged into the
accessory power socket are turned
of f so they do not run down the
battery.
