wheel Acura TL 2009 Workshop Manual

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The emergency
brake assist system increases the
stopping f orce when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, reduces their ef f ectiveness and
reduces brake pad lif e. In addition,
f uel economy can be reduced. It also
keeps your brake lights on all the
time, conf using drivers behind you.Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check your brakes af ter driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious and alert in your driving.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
All f our brakes have audible brake
wear indicators.

The anti-lock brake system (ABS)
helpspreventthewheelsfrom
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the f ront-to-rear
braking distribution according to
vehicle loading.
Let the ABS work f or you by always
keeping f irm, steady pressure on the
brake pedal. This is sometimes
ref erred to as ‘‘stomp and steer.’’If this indicator comes on, the anti-
lock f unction of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly
pumpingthebrakes.Ondry

thebrakepedalveryhardbeforethe
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
If the ABS indicator comes on while
driving, test the brakes as shown on
page .
When the ABS indicator comes on,
you will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display.597
You should never pump the brake pedal.

If the ABS indicator and the brake
system indicator come on together,
and the parking brake is f ully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page . If the brakes f eel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.
The VSA indicator will come on
alongwiththeABSindicator.such as trying to take a
corner too f ast or making a sudden
lane change. Always drive at a safe
speed f or the road and weather
conditions.
Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road. on loose or
uneven surf aces, such as gravel or
snow, than a vehicle without anti-
lock.
It only helps with the
steering control during braking.
597 Important Saf ety Reminders
A BS will not prevent a skid that
results f rom changing direction
abruptly,
A BS cannot prevent a loss of
stability. A vehicle with A BS may require a
longer distance to stop
A BS does not reduce the time or
distance it takes to stop the
vehicle.

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.
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 ).Hillstartassistmaynotpreventyour

Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

dealer as soon as possible.
This indicator and the warning
message on the multi-inf ormation
display will go of f , af ter several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualif ied technician.
If you have a f lat tire, the low tire
pressure/TPMS indicator and tire
monitor indicator will come on.
Replace the indicated f lat tire with
thecompactsparetire(seepage
).
After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. Af ter several miles
(kilometers) driving, this indicator
begins to f lash, then stays on again.
You will also see a ‘‘CHECK TPMS
SYSTEM’’ message on the multi-
inf ormation display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct. If the low tire pressure/TPMS
indicator and the low tire position on
the low tire pressure monitor do not
go out af ter inf lating the tires to the
specified values, have your dealer
check the system as soon as possible.
