This indicator normally comes on f or
a f ew seconds when you turn the
ignition switch to the ON (II)
position. If it comes on at any other
time, there is a problem in the ACC
system. If this happens, take the
vehicle to your dealer to have it
checked.
The ACC system cannot be used
while this indicator is on.
The vehicle speed decreases
below22mph(35km/h).
Driving on a mountainous road, or
driving of f road f or extended
periods.
When the VSA indicator comes on. When the ABS or VSA is activated.
Abrupt steering wheel movement.
If ACC is cancelled by any these
conditions, wait until the condition
improves, then press the RES/
ACCEL button to restore ACC.
When you do this, the vehicle will
resume its set cruising speed.
If you turn the ignition switch to the
ACCESSORY (I) or LOCK (0)
position af ter ACC was automatically
cancelled, the set speed is erased,
and you must enter it again (see
page ).
Poor weather (rain, f og, snow, etc.)
When the radar sensor in the front
grille gets dirty.
The vehicle ahead of you cannot
be detected.
An abnormal tire condition is
detected, or the tires are skidding.
When ACC is automatically canceled,
the beeper sounds about 1 second,
and an ACC OFF message appears
on the multi-inf ormation display f or 3

To hear general HFL inf ormation,
including help on pairing a phone
or setting up the system, say
‘‘Tutorial.’’
For help at any time, including a
list of available commands, say
‘‘Hands f ree help.’’
Many commands can be spoken
together. For example, you can
say ‘‘Call 123-456-7890’’ or ‘‘Dial
Peter.’’
When HFL is in use, navigation
voice commands cannot be
recognized.
Tochangethevolumelevelof
HFL, use the audio system volume
knob or the steering wheel volume
controls.
Try to reduce all background
noise. If the microphone picks up
voices other than yours,
commands may be misinterpreted. Press and release the HFL Talk

Larger or smaller wheels and tires
can interf ere with the operation of
your vehicle’s anti-lock brakes and
other systems.
Modif ying your steering wheel or
any other part of your vehicle’s
saf ety systems could make the
systems inef f ective.
If you plan to modif y your vehicle,
consult your dealer.
Raising your vehicle with a non-
Acura suspension kit can af f ect
the handling and stability. Lowering the vehicle with a non-
Acura suspension kit that
signif icantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.
Removing parts f rom your vehicle,
or replacing components with non-
Acura components could seriously
af f ect your vehicle’s handling,
stability, and reliability.
Herearesomeexamples:
Non-Acura wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).

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 brake pedal
assist f unction increases the f orce
you apply to the brake pedal during
an emergency stop. When the brake
pedal assist is activated, the e-
pretensioners (if equipped) tighten
f ront seat belts (see page ). The
anti-lock brake system (ABS) helps
you retain steering control when
braking very hard (see page ).
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.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.
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.
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.

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.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
pavement, you will need to press on
thebrakepedalveryhardbeforethe
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
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.’’ 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. When the ABS indicator comes on,
you will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display.
You should never pump the brake pedal.

on loose or
uneven surfaces, such as gravel or
snow, than a vehicle without anti-
lock.
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 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.
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.

Important Saf ety Reminders
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

A BS cannot prevent the loss of

The CMBS does not activate if the
speed dif f erence between the two
vehicles is less than 10 mph (15
km/h). CMBS may also not
activate if you turn the steering
wheel to avoid the collision.
When the CMBS activates, the brake
lights also come on.
The collision mitigation brake
system (CMBS) can assist you when
there is a possibility of your vehicle
hitting the vehicle in f ront of you. It
is designed to reduce the speed of
your vehicle before an unavoidable
collision occurs and, if possible, to
alert you to a potential collision while
thereistimetopreventit.Hereisa
brief description of what the CMBS
can do:
When your speed is above 10 mph
(15 km/h), the CMBS radar
sensor in the f ront grille can sense
a vehicle ahead of you. When your
vehicle gets too close to the
vehicle ahead of you, the system
mayactivateawarningbeep,
causing automatic application of
the brakes, and causing the
e-pretensioners to tighten the
f ront seat belts (see page ). The CMBS consists of a radar
sensor in the f ront grille, a brake
actuator in the engine compartment,
an indicator on the instrument panel,
seat belt e-pretensioners on the f ront
seats,andanon/off switchonthe
dashboard.
