Your vehicle is equipped with
Bluetooth
HandsFreeLink(HFL).
HFL uses Bluetooth
technology to
link your cell phone to your vehicle.
With HFL, you can place and receive
calls through your vehicle’s audio
system, without the distraction of
handling your cell phone. To use this
f eature, you need a Bluetooth-
compatible cell phone with the
Hands Free Prof ile. For more
inf ormation, and a list of compatible
cell phones, visit
, or call 1-888-528-7876.
In Canada, visit , or call
1-888-9-ACURA-9. The HFL is
available in English on U.S. models,
andinbothEnglishandFrenchon
Canadian models. To change the
language, see page . HFL recognizes simple voice
commands, such as phone numbers
and names. It uses these commands
to automatically dial, receive, and
store numbers. For more
inf ormation on voice control, see
UsingVoiceControlonpage.
Here are the main features of the
HFL. Instructions f or using the HFL
begin on page . Bluetooth is the wireless technology
that links your phone to the HFL.
TheHFLusesaClass2Bluetooth,
which means the maximum range
between your phone and vehicle is
30 f eet (10 meters).
Bluetooth
is a registered trademark
of Bluetooth SIG, Inc.
To use the HFL, your phone must
have approved Bluetooth capability
along with the Hands Free Prof ile.
This type of phone is available
through many phone makers and
cellular carriers. You can also find an
approved phone by visiting ,orby
calling the HandsFreeLink
consumer support at 1-888-528-7876.
In Canada, visit , or call
1-888-9-ACURA-9.
The HFL can store up to 50 names
and phone numbers in its phonebook.
Withalinkedphone,youcanthen
automatically dial any name or
number in the phonebook.
Here are the main components of
the HFL:
The HFL microphone is on the
ceiling console. The microphone is
shared with the navigation system.
With a linked phone, the HFL allows
you to send and receive calls in your
vehicle without holding the phone.

Because your vehicle rides higher
of f the ground, it has a high center
of gravity that can cause it to roll
over if you make abrupt turns. Utility
vehicles have a signif icantly higher
roll over rate than other types of
vehicles. Your vehicle has higher ground
clearance that allows you to travel
over bumps, obstacles, and rough
terrain. It also provides good
visibility so you can anticipate
problems earlier.To prevent rollovers or loss of
control:
Take corners at slower speeds
than you would with a passenger
vehicle.
Avoid sharp turns and abrupt
maneuvers whenever possible.
Do not modif y your vehicle in any
way that would raise the center of
gravity.
Do not carry heavy cargo on the
roof . Your vehicle is equipped with a
super handling-all wheel drive
(SH-AWD) system. When the
system senses a loss of one or more
wheel traction, it automatically
transfers some power to the other
wheels. This gives you better
traction and mobility.
You still need to exercise the same
care when accelerating, steering, and
brakingthatyouwouldinatwo-
wheel drive vehicle.

guidelines. 321

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.When VSA activates, you will see the
VSA activation indicator blink (see
page ).
If this indicator comes on 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. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
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 f rom the VSA
hydraulic system. You will also see
the VSA activation indicator blink.
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. 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.
If the low tire pressure/TPMS
indicator comes on (see page ),
or the multi-information display
shows a ‘‘CHECK TPMS SYSTEM’’
message with the indicator flashing
(see page ), the VSA system
automatically turns on even if the
VSA system is turned off with the
VSA OFF switch. In this case, you
cannot turn the VSA system of f by
pressing the VSA OFF switch again.
You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
inf ormation display if there is a
problem with the VSA system.
The main f unction of the
VSA system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control f unction. 67

This switch is under the driver’s side
vent. To turn the VSA system on and
of f , press and hold it until you hear a
beep.
When VSA is off, the VSA activation
indicator comes on as a reminder.
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 the same size
and type as your original tires (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.
Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement. 364

Your vehicle has been designed
primarily to carry passengers and
their cargo. You can also use it to
tow a trailer if you caref ully observe
the load limits, use the proper
equipment, and f ollow the guidelines
in this section.
Be sure to read thesectiononpage
if you plan to tow of f paved
surf aces.
The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,500 lbs (680 kg).
Towing a load that is too heavy can
seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain. Theweightthatthe
tongue of a f ully-loaded trailer puts
on the hitch should be approximately
10% of the total trailer weight. Too
much tongue load reduces f ront-tire
traction and steering control. Too
little tongue load can make the
trailer unstable and cause it to sway.

Exceeding any load limit or

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
Quality grades can be f ound where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate.The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
