engine Acura CL 2003 Service Manual

The VSA system cannot enhance the
car’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
suf f icient margin of saf ety.When VSA activates, you will see the
VSA Activation indicator blink.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. You will also see
the VSA Activation Indicator blink. The Vehicle Stability Assist system
helps to stabilize the vehicle during
cornering if the car 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 braking.On Type-S with A/T

If the VSA indicator comes on while
driving, pull to the side of the road
when it is saf e and turn of f the
engine. Reset the system by
restarting the engine, and watch the
VSA system indicator. If the
indicator remains on, or comes back
on while driving, have the VSA
system inspected by your Acura
dealer.When VSA is off, the VSA Activation
Indicator light comes on as a
reminder. Pressing the switch again
turns the system back on.
If the indicator does not come on
when the ignition switch is turned
ON(II),theremaybeaproblem
with the VSA system. Have your
dealer inspect your car as soon as
possible.
Without VSA, your car 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 .
The VSA system indicator (see page
) comes on and stays on when
there is a problem with the VSA
system. The VSA Activation
indicator will also come on.
The VSA system indicator may come
on along with the ABS indicator if
there is a problem with the anti-lock
brake system. 62

VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the car.Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of 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
car. Exercise the same caution
during winter driving as you would if
your car was not equipped with VSA.270

Your Acura has been designed
primarily to carry passengers and
their cargo. You can use it to tow a
trailer if you caref ully observe the
load limits, use the proper equipment,
and f ollow the guidelines in this
section.The total
weight of the trailer and
everything loaded in it must not
exceed 1,000 lbs (450 kg). Towing
a load that is too heavy can
seriously af f ect your car’s
handling and perf ormance. It can
also damage the engine and
drivetrain. The weight that
the tongue of a f ully-loaded trailer
puts on the hitch should be
approximately 10 percent of the
trailer weight. Too little tongue
load can make the trailer unstable
and cause it to sway. Too much
tongue load reduces f ront-tire
traction and steering control.

The added weight, length, and

Maintenance
Maint enance225

Be sure
there is adequate ventilation
whenever you operate the engine.
Let the
engine and exhaust system cool
bef ore touching any parts.
Do
not run the engine unless in-
structed to do so. Read the instructions before you
begin, and make sure you have the
tools and skills required.
To reduce the possibility of f ire or
explosion, be caref ul when working
around gasoline or batteries. Use a
commercially available degreaser or
parts cleaner, not gasoline, to clean
parts. Keep cigarettes, sparks, and
flames away from the battery and all
f uel-related parts.
Bef ore you begin any maintenance,
make sure your car is parked on
level ground and that the parking
brake is set. Also, be sure the engine
is of f . This will help to eliminate
several potential hazards:
You should wear eye protection and
protective clothing when working
near the battery or when using
compressed air.
