avoid transmission damage, come
to a complete stop before shifting
into Park. The shift lever must be in
Park before you can remove the key
from the ignition switch.
Press the brake
pedal and press the release button
on the front of the shift lever to shift
fr om Park to reverse. To shift from
reverse to neutral, come to a
completestop,andthenshift.Press
the release button before shifting
into reverse from neutral.
Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop briefly with
the engine idling. Shift to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from neutral to
another gear. Use
this position for
your norm al driving. The
transmission automatically selects a
suitable gear (1 through 5) for your
sp eed and acceleration. You may
notice the transmission shifting up at
higher engine speeds when the
engine is cold. This helps the engine
warm up faster.
This position mechani-
cally locks the transmission. Use
Park whenever you are turning off or
starting the engine. To shift out of
Park, you must press on the brake
pedal and press the release button
on the shif t lever. Make sure your
f oot is of f the accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see on
page . 338
Do this:
Press the brake pedal, and
press the shift lever release
button.

µIf you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
rpm below the red zone.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone.
This position is
similar to D, except only the f irst
three gears are selected. Use D
when towing a trailer in hilly terrain,
or to provide engine braking when
going down a steep hill. D can also
keep the transmission f rom cycling
between third, f ourth, and f if th gears
in stop-and-go driving.
ForfasteraccelerationwheninD or
D, you can get the transmission to
automatically downshif t by pushing
the accelerator pedal to the floor.
The transmission will shif t down one,
two, or three gears, depending on
your speed. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal and pressing the release
button does not work.
Remove the key from the ignition
switch. Set the parking brake.

Check the indicator on the
instrument panel to verif y that the
security system is set. If the vehicle is f acing uphill, turn
the front wheels away from the
curb. Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes. If the vehicle is f acing downhill,
turn the front wheels toward the
curb, and set the parking brake.
Make sure the moonroof and the
windows are closed.
Turn of f the lights.
Place any packages, valuables, etc.
in the cargo area or take them
with you.
Lock the doors and the tailgate.
Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.

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. 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 brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
ef f ectiveness and 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.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.
All f our brakes have audible brake
wear indicators.
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.
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.

The anti-lock brake system (ABS)
helpspreventthewheelsfrom
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the front-to-rear
braking distribution according to
vehicle loading. If
this indicator comes on, the anti-
lock function 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 vehic le as
soon as possible.
You
will feel 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 feel 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 .
You
will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
info rmation display (see page ).
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.’’ 43281

be shut down.
such as trying to take a
corn er too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions.
Always steer moderate ly
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.
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.

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

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 noise from the modulator. When
VSA activates, you will see the
VSA activation indicator blink. There
mayalsobesomenoisefromthe
modulator.
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 surfaces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
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 deale r. 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 vehic le as
soon as possible.
You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure indicator
comes on (see page ), or the
multi-info rmation display shows a
‘‘CHECK TPMS SYSTEM’’ message
(see page ), the VSA system
automatically turns on even if you
turn it of f with the VSA OFF switch.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
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.

A 4-pin gray connector is available as
an option at your dealer. This
connector has all of the circuits
required to install most electric
trailer brake controllers. A jumper
harness to adapt your electric trailer
brake controller to the vehicle is
included with the optional Genuine
Acura trailer hitch kit. To obtain a
connector and a trailer hitch kit, see
your dealer.
Have a qualif ied mechanic install
your trailer brake controller
f ollowing the trailer brake controller
manuf acturer’s instructions. Failure
to properly install the trailer brake
controller may increase the distance
it takes f or you to stop your vehicle
when towing a trailer.
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 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.
Seeyourtrailermanufacturerfor
more inf ormation on installing
electric brakes.
We strongly recommend that you
have your dealer install a class 3
hitch. Using non-Acura equipment
may result in serious damage to your
vehicle.
Read the trailer manufacturer’s
instructions, and select the
appropriate draw bar f or the height
of the trailer you will be towing.
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.

When towing a trailer, we
recommend that you carry a full-size
spare wheel and tire for your vehicle
and trailer. See page for 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.
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. 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. 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.
Use this illustration to identif y each
terminal in the trailer brake
controller connector.
