Vehicle Stability Assist
(VSA) System Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. It flashes when VSA is
active (see page 467).
If it comes on and stays on at any
other time, there is a problem with
the VSA or Hill Start Assist system.
You will also see a ‘‘CHECK VSA
SYSTEM ’’message on the multi-
information display (see page 87).
Take your vehicle to a dealer to have
it checked. Without VSA, your
vehicle still has normal driving
ability, but will not have VSA traction
and stability enhancement. For more
information, see page 467.
This indicator may also come on if
there is a problem with the trailer
stability assist function (see page
492).
VSA Off Indicator
It comes on as a reminder that you
have turned off the vehicle stability
assist (VSA) system.
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. For more information, see
page 467.
Turn Signal and
Hazard Warning
Indicators
The left or right turn signal indicator
blinks when you signal a lane change
or turn. If an indicator does not blink
or blinks rapidly, it usually means
one of the turn signal bulbs is burned
out (see page 523). Replace the bulb
as soon as possible, since other
drivers cannot see that you are
signaling.
When you press the hazard warning
button, both turn signal indicators
and all turn signals on the outside of
the vehicle flash.

Break-in Period
Help assure your vehicle's future
reliability and performance by paying
extra attention to how you drive
during the first 600 miles (1,000 km).
During this period:●
Avoid full-throttle starts and rapid
acceleration.
●
Avoid hard braking for the first 200
miles (300 km).
●
Do not change the oil until the
multi-information display indicates
it is needed.
●
Do not tow a trailer.
You should also follow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Fuel Recommendation
Your vehicle is designed to operate
on premium unleaded gasoline with a
pump octane of 91 or higher. If this
octane grade is unavailable, regular
unleaded gasoline with a pump octane
of 87 or higher may be used
temporarily. The use of regular
unleaded gasoline can cause metallic
knocking noises in the engine and
will result in decreased engine
performance. The long-term use of
regular-grade gasoline can lead to
engine damage.
We recommend quality gasolines
containing detergent additives that
help prevent fuel system and engine
deposits.
In addition, in order to maintain good
performance, fuel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
fuel additives such as MMT. Use of gasoline with these additives
may adversely affect performance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contact your
dealer for service.
Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10% ethanol by
volume and up to 15% MTBE by
volume. Do not use gasoline
containing methanol.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
For further important fuel-related
information for your vehicle, or
information on gasoline that does not
contain MMT, visit My Acura at
owners.acura.com.
In Canada, visit
www.acura.ca
for additional
information on gasoline.

Fuel Economy Factors
The following factors can lower your
vehicle's fuel economy:●
Aggressive driving (hard
acceleration and braking)
●
Excessive idling, accelerating and
braking in stop-and-go traffic
●
Cold engine operation (engines
are more efficient when warmed
up)
●
Driving with a heavy load or the air
conditioner running
●
Improperly inflated tires
Improving Fuel EconomyVehicle MaintenanceA properly maintained vehicle
maximizes fuel economy. Poor
maintenance can significantly reduce
fuel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the multi-
information display (seeOwner's
Maintenance Checks on page 507).For example:
●
Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page 511).
●
Maintain proper tire inflation
－
An underinflated tire increases
‘‘ rolling resistance, ’’which reduces
fuel economy.
●
Avoid carrying excess weight in
your vehicle －It puts a heavier
load on the engine, increasing fuel
consumption.
●
Keep your vehicle clean －In
particular, a build-up of snow or mud
on your vehicle's underside adds
weight and rolling resistance.
Frequent cleaning helps your fuel
economy.
Drive Efficiently●
Drive moderately －Rapid
acceleration, abrupt cornering, and
hard braking increase fuel
consumption.
●
Observe the speed limit －
Aerodynamic drag has a big effect
on fuel economy at speeds above
45 mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
●
Always drive in the highest gear
possible －If your vehicle has a
manual transmission, you can
boost your fuel economy by up
shifting as early as possible.
●
Avoid excessive idling －Idling
results in 0 miles per gallon (0 kms
per liter).

Load Limits
The maximum load for your vehicle
is 1,150 lbs (525 kg).
See Tire And Loading Information
label attached to the driver's
doorjamb.
Label Example
This figure includes the total weight
of all occupants, cargo, and
accessories, and the tongue load if
you are towing a trailer.
Overloading or improper
loading can affect handling and
stability and cause a crash in
which you can be hurt or killed.
Follow all load limits and other
loading guidelines in this
manual.
Steps for Determining Correct Load
Limit －
(1) Locate the statement ‘‘The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs. ’’on your
vehicle's placard.
(2) Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs. (4) The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the ‘‘XXX ’’amount
equals 1,400 lbs. and there will
be five 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity
is 650 lbs.
(1,400 －750 (5 ╳150) = 650
lbs.)
(5) Determine the combined weight of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed the
available cargo and luggage load
capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity
of your vehicle.

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/TPMS
indicator comes on, or the multi-
information display shows a ‘‘CHECK
TPMS SYSTEM ’’message with the
indicator flashing (see page 452), the
VSA system automatically turns on
even if the VSA system is turned off
by pressing the VSA OFF switch. If
this case, you cannot turn the VSA
system off by pressing the VSA OFF
switch again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement. VSA Off Switch
This switch is under the driver's side
vent. To turn the VSA system on and
off, press and hold it until you hear a
beep.
When VSA is off, the VSA off
indicator comes on as a reminder.
Press and hold the switch again. It
turns the system back on. With the
VSA off, the trailer stability assist
function is also turned off (see page
492).VSA is turned on every time you start
the engine, even if you turned it off
the last time you drove the vehicle.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off. You should only attempt to
free your vehicle with the VSA off if
you are not able to free it when the
VSA is on.
Immediately after freeing 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.

VSA and Tire Sizes
Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page 539).
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.Hill Start Assist
Your vehicle is equipped with a hill
start assist feature to help prevent
the vehicle from rolling on steep
inclines as you move your foot from
the brake pedal to the accelerator.
This feature starts operating a few
seconds after you are in any drive
gear position (when faced uphill) or
in reverse (when faced downhill).
This feature requires that the vehicle
has come to a complete stop before it
can work.
Hill start assist may not hold a
heavily loaded vehicle, such as when
your vehicle is connected to a trailer,
or prevent your vehicle from rolling
downhill on a very steep or slippery
slope.

Important Precautions
Like all assistance systems, BSI has
limitations. Over-reliance on BSI may
result in a collision. Always look in
your mirrors, to either side of your
vehicle, and behind you for other
vehicles before changing lanes.The system should be turned off
when towing a trailer. Due to the
added mass and resulting changes in
radar coverage, the system cannot
operate as intended, and detection of
the trailer itself by the radar sensors
may cause the BSI alert indicators to
illuminate.Limitations
The BSI alert indicators may not
illuminate under the following
circumstances:
●
The speed difference between
your vehicle and a vehicle
approaching from behind is
greater than 31 mph (50 km/h).
●
A vehicle is parked in a side lane.
●
The speed difference between
your vehicle and the vehicle you
are passing is greater than 6 mph
(10 km/h).
●
An object not detected by the
radar sensors approaches or
passes your vehicle.
