2003 Acura CL brakes

Your Acura 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 ABS helps
you retain steering control when
braking very hard.
Put your f oot on the brake pedal only
when you intend to brake. Resting
your f oot on the pedal keeps the
brakes applied lightly, causing them
to build up heat. Heat build-up can
reduce how well your brakes work. 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 downshif ting to a lower
gear and taking your f oot of f the
accelerator pedal.
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. Since a
longer distance is needed to stop
with wet brakes, be extra cautious
and alert in your driving.
All f our brakes have audible brake
wear indicators.
When the brake pads need replacing,
you will hear a distinctive metallic
‘‘screeching’’ sound when you apply
the brakes. If you do not have the
brake pads replaced, they will begin
screeching all the time.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not conf use this with the

this defeats the
purpose of the ABS. Let the ABS
work f or you by always keeping f irm,
steady pressure on the brake pedal
as you steer away from the hazard.
This is sometimes ref erred to as
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
pumping the brakes.
Activation varies with the amount of
traction your tires have. On dry
pavement, you will need to press on
thebrakepedalveryhardbeforeyou
activate the ABS. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
Your car has an Anti-lock Brake
System (ABS) as standard
equipment. ABS helps to prevent the
wheels f rom locking up and skidding
during hard braking, allowing you to
retain steering control.
When the f ront tires skid, you lose
steering control; the car continues
straightaheadeventhoughyouturn
the steering wheel. The ABS helps to
prevent lock-up and helps you retain
steering control by pumping the
brakes rapidly; much f aster than a
person can do it.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the car (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.

Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your car to veer into
oncoming traffic or off the road. it
only helps with steering control
during braking. You should always
maintain a saf e f ollowing distance
f rom other vehicles. on loose or
uneven surf aces, such as gravel or
snow, than a vehicle without anti-
lock. Slow down and allow a greater
distance between vehicles under
those conditions.
The ABS is self -checking. If anything
goes wrong, the ABS indicator on
the instrument panel comes on (see
page ). This means the anti-lock
f unction of the braking system has
shut down. The brakes still work like
a conventional system without anti-
lock, providing normal stopping
ability. You should have the dealer
inspect your car as soon as possible.61

If the brakes overheat while TCS is

This indicator will come on along
with the ABS indicator if there is a
problem in the anti-lock brake
system (seeon page
).
The TCS indicator may occasionally
come on f or one or two seconds and
then go out. This is normal.
The Traction Control System turns
on every time you start the engine,
even if you turned it of f the last time
you drove the vehicle.
The TCS indicator comes on or

tions:
When you turn the ignition switch
to ON (II).
When you manually turn of f TCS. If the TCS indicator comes on and
stays on for more than 10 minutes
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
TCS indicator. If the indicator
remains on, or comes back on while
driving, have the system inspected
by your Acura dealer. You can still
drive the vehicle without TCS.

wheelspin.
If the system’s diagnostics senses
a problem with TCS, the indicator
will come on and stay on.
If the brakes overheat, the
indicator will come on. 208

µExercise extra caution when driving
in rain af ter a long dry spell. Af ter
months of dry weather, the f irst
rains bring oil to the surf ace of the
roadway, making it slippery.
Rain, f og, and snow conditions
require a dif f erent driving technique
because of reduced traction and
visibility. Keep your car well-
maintained and exercise greater
caution when you need to drive in
bad weather. The cruise control
should not be used in these
conditions. Always drive
slower than you would in dry
weather. It takes your car longer to
react, even in conditions that may
seem just barely damp. Apply
smooth, even pressure to all the
controls. Abrupt steering wheel
movements or sudden, hard appli-
cation of the brakes can cause loss of
control in wet weather. Be extra
cautious f or the f irst f ew miles
(kilometers) of driving while you
adjust to the change in driving
conditions. This is especially true in
snow. A person can f orget some
snow-driving techniques during the
summer months. Practice is needed
to relearn those skills.

Always use saf ety chains. Make sure
they are secured to both the trailer
and hitch, and that they cross under
the tongue so they can catch the
trailer if it becomes unhitched.
Leave enough slack to allow the
trailer to turn corners easily, but do
not let the chains drag on the ground.
Acura recommends that any trailer
having a total weight of 1,000 lbs
(450 kg) or more be equipped with
its own electric or surge-type brakes.
If you choose electric brakes, be
sure they are electronically actuated.
Do not attempt to tap into your
vehicle’s hydraulic system. No
matter how successf ul it may seem,
any attempt to attach trailer brakes
to your vehicle’s hydraulic system
will lower braking ef f ectiveness and
create a potential hazard.
Any hitch used on your vehicle must
be properly bolted to the underbody. Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, and
how much load you are towing.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and that it meets
f ederal, state, province, and local
regulations.
The best way to conf irm that vehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, check the tongue
load the f irst time you set up a
towing combination (a f ully-loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.

Your vehicle tires and spare are
properly inf lated (see page ),
and the trailer tires and spare are
inflated as recommended by the
trailer maker.
When preparing to tow, and bef ore
driving away, be sure to check the
f ollowing:
The vehicle has been properly
serviced, and the tires, brakes,
suspension, and cooling system
are in good operating condition.
All weights and loads are within
limits (see pages and ).
Thehitch,safetychains,andany
other attachments are secure.
Allitemsonandinthetrailerare
properly secured and cannot shif t

The lights and brakes on your
vehicle and the trailer are working
properly.
Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.
