Check the brakes after 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 in your driving.
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 anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
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.
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. Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you. Braking System DesignBrake Wear Indicators

The anti-lock brake system (ABS)
helps prevent the brakes f rom
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.
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
may hear some noise. This is normal:
it is the ABS rapidly pumping the
brakes. On dry pavement, you will
need to press on the brake pedal
very hard before the ABS activates.
However, you may f eel the ABS
activate immediately if you are trying
to stop on snow or ice.
If the indicator comes on while
driving, test the brakes as instructed
on page .274
You should never pump the brake pedal.

on loose or
uneven surf aces, such as gravel or
snow, than a vehicle without anti-
lock.
If the ABS indicator and the brake
system indicator come on together
and the parking break is f ully
released, the front-to-rear braking
distribution system may also shut
down.
It only helps with steering
control during braking.
such as trying to take a
corner too f ast or making a sudden
lane change.
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. Important Saf ety Reminders 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.
A BS will not prevent a skid that
results f rom changing direction
abruptly,
A BS cannot prevent a loss of
stability.

When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some unusual noise f rom the
modulator.When VSA activates, you will see the
VSA activation indicator blink. There
may also be some unusual noise
f rom the modulator.
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, or comes
back on while driving, have the VSA
system inspected by your 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. The vehicle stability assist (VSA)
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.

Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.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 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
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
When VSA is off, the VSA activation
indicator comes on as a reminder.
If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
This switch is under the lef t vent.
Press it to turn the VSA system on

Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase Acura
equipment whenever possible.
Your dealer of f ers a trailer package
that includes a hitch, a ball mount, a
wiring harness, a heavy-duty
transmission f luid cooler.
Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed, maintained, and
also meets state, f ederal, province,
and local regulations.We strongly recommend that you
have your dealer install an Acura
hitch and use the required f luid
coolers. Using non-Acura equipment
may result in serious damage to your
vehicle.
To help prevent overheating, a
heavy-duty transmission f luid cooler
and a heavy-duty power steering
f luid cooler are required f or trailer
towing. These coolers are available
only f rom your dealer.
A weight distributing hitch is not
recommended f or use with your
vehicle, as an improperly adjusted
weight distributing hitch may reduce
handling, stability, and braking
perf ormance.
Check the weight of the unhitched
trailer. Limit: See page .
Calculate the tongue load.
Subtract the weight in Step
5f rom
the

Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.
If you choose electric brakes, be
sure they are electrically 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.
Seeyourtrailermanufacturerfor
more inf ormation on installing
electric brakes.Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and 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.
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
Many states and provinces require
special exterior 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.When towing a trailer, we
recommend that you carry a f ull-size
spare wheel and tire for your vehicle
and trailer. See page f or proper
tire size, page f or how to store a
full size wheel and tire, and page
f or inf ormation on changing a
flat tire.
Remember to unhitch the trailer
bef ore changing a f lat. Ask your
trailer sales or rental agency where
and how to store the trailer’s spare
tire. 255

Trailer lights and equipment must
comply with f ederal, state, province,
and local regulations. Check trailer
light requirements f or the areas
where you plan to tow, and use only
equipment designed f or your vehicle.
To get to your vehicle’s trailer
lighting connector, open the tailgate,
remove the cargo cover, then
remove the rear panel trim. The
connector is on the lef t side.We recommend that you have your
dealer install a Acura wiring harness
and converter. This harness has
been designed f or your vehicle.
If you use a non-Acura trailer
lighting harness and converter, you

The vehicle has been properly
serviced, and the tires, brakes,
suspension, cooling system, and
lights are in good operating
condition. If you tow f requently,

When climbing hills, closely watch
your temperature gauge. If it nears
the red (hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the transmission shif ts f requently
while going up a hill, shif t to D3.
If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shif t down to D . Do
not ‘‘ride’’ the brakes.Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Always drive slowly and have
someone guide you when backing up.
Grip the of the steering wheel,
then turn the wheel to the left to get
the trailer to move to the lef t. Turn
the wheel to the right to move the
trailer to the right.
Follow all normal precautions when
parking, including putting the
transmission in Park and f irmly
setting the parking brake. Also, place
wheel chocks at each of the trailer’s
tires.If the vehicle’s tires slip when
retrieving a boat f rom the water,
shif t to f irst gear, and turn on VTM-4
Lock (see page ). Disengage
VTM-
4Lock as soon as the boat is
out of the water to prevent damage
to the VTM- 4system. 206
