2004 Acura TL engine

The Vehicle Stability Assist system
helps to stabilize the vehicle during
cornering if the vehicle turns more
or less than desired. It also assists
you in maintaining traction while
accelerating on loose or slippery
road surf aces. It does this by
regulating the engine’s output, and
by selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times.If the VSA system indicator comes
on while driving, pull to the side of
theroadwhenitissafe,andturnoff
the engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on, or comes
back on while driving, have the VSA
system inspected by an Acura dealer.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
When VSA activates, you will see the
VSA Activation indicator blink.
In manual transmission models, if
the VSA system is of f and you
accelerate f rom a stop, the vehicle
may pull, and it may take extra effort
to return the steering wheel to
center. VSA A ctivation Indicator

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.

If you have the required service
perf ormed but do not reset the
display, or reset the display without
perf orming the service, the system
will not show the proper
maintenance intervals. This can lead
to serious mechanical problems
because you will no longer have an
accurate record of when
maintenance is needed.If the indicated maintenance service
is not done and the remaining engine
oil lif e gets less than 0 percent, you
will see the message ‘‘SERVICE
PAST DUE’’ on the display.
Immediately have the service
perf ormed, and make sure to reset
the display as previously described.Your authorized Acura dealer knows
your vehicle best and can provide
competent, ef f icient service.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done
by any qualif ied service f acility or
person who is skilled in this type of
automotive service. Keep all receipts
as proof of completion, and have the
person who does the work f ill out the
Maintenance Record. Check your
warranty booklet f or more
inf ormation.
We recommend the use of Acura
parts and f luids whenever you have
maintenance done. These are
manuf actured to the same high-
quality standards as the original
components, so you can be conf ident
of their performance and durability.
