Each paddle shift operation makes a single gear
change.
To change gears continuously, release the paddle
shifter before pulling it again for the next gear.
If the sequential mode gear selection indicator blinks
when you try to shift up or down, this means your
vehicle speed is not in its allowable gear range.
Slightly accelerate to shift up and decelerate to shift
down while the indi cator is blinking.
In SPORT mode, to prioriti ze the engine performance
enhancement, the transmission may not allow for
shifting up while the engine speed is low.

uuWhen Driving uVehicle Stability Assist (VSA® ), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability Assist (VSA®), aka Electronic
Stability Control (ESC), System
Helps to stabilize the vehicle during cornerin g if the vehicle turns more or less than
what was intended. It also assists in mainta ining traction on slippery surfaces. It does
so by regulating engine and motor ou tput and selectively applying the brakes.
When VSA ® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic system . You will also see
the indicator blink.
■VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
VSA ® may not function properly if tire type and size
are mixed. Make sure to use the same size and type
of tire, and the air pr essures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stab ility Control (ESC). The
system also includes a traction control function.

Driving
This button is on the driver side control panel.
To partially turn the VSA features on and off,
press and hold it until you hear a beep.
The traction control stop s fully functioning,
allowing the wheels to spin more freely at low
speed. The VSA ® OFF indicator will also come
on.
To turn it on again, press the (VSA ® OFF)
button until you hear a beep.
VSA ® is turned on every time you turn the
power system on, even if you press the button
the last time you drove the vehicle.
■VSA ® OFF Button1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
With the button pressed, your vehicle will have
normal braking and corn ering ability, but VSA®
traction and stability enhancement becomes less
effective.
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the button pressed.
When the button is pressed, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the button
pressed if you are not able to free it without.
Immediately after freeing your vehicle, be sure to
press the button again. We do not recommend
driving your vehicle wi th the button pressed
(indicator on).
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.

Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering.1 Agile Handling Assist
The agile handling assist cannot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the engine

Driving
SPORT HYBRID Super Handling-All Wheel DriveTM
(SPORT HYBRID SH-AWD ®)
The system controls and transfers varying amounts of motor and/or engine torque
to each wheel in accordance with the driving conditions.
SPORT HYBRID SH-AWD ® helps to enhance driving stability, and lets you handle
situations like slippery surf aces, such as snow, sand, mud, and steep hills, better
than when driving with standard two wheel drive. However, the system does not
help to enhance braking. Be cautious about the following:
• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.
1SPORT HYBRID Super Handling-All Wheel DriveTM (SPORT
HYBRID SH-AWD ®)
Do not drive through deep water.
The SPORT HYBRID SH-AWD ® system may not
function properly if tire type and size are mixed.
Make sure to use the same size and type of tire, and
the air pressures as specified. 2 Tire and Wheel Replacement P. 494

Brake System
Use the parking brake to keep the vehicle stationary when parked. You can
manually apply and release, or automatically release it.
■Manual operations
Use the electric parking brake switch to apply or release the brake. Manually
releasing the parking brake using the swit ch helps your vehicle start slowly and
smoothly when facing down hill on steep hills.
■To apply manually
Pull the electric parking brake switch up gently
and securely.
u The electric parking brake indicator
comes on.
■To release manually
1. Depress the brake pedal.
2. Press the electric parking brake switch.
u The electric parking brake indicator goes

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. 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.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have your
vehicle checked by a dealer immediately.
The ABS does not reduce the ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after turning the power
system on or while driving. This is normal.

uuParking Your Vehicle uWhen Stopped
Driving
If during in Auto Engine Stop, the gear position changes to (P and the engine
restarts automatically unde r the following conditions:
• The power system is on.
• The gear position is not in
(P.
• You unfasten the driver side seat belt and open the door.
1When Stopped
NOTICE
The following can damage the driveline:•Depressing the accelera tor and brake pedals
simultaneously.
•Changing into ( P before the vehicle stops
completely.
When facing uphill, do not hold the vehicle by
depressing the accelerator pedal.
Doing so may cause the power system to overheat
and fail.
In extremely cold temper atures, the parking brake
may freeze up if applied. If such temperatures are
expected, do not apply the parking brake but, if
parking on a slope, either turn the front wheels so
they will contact the curb if the vehicle rolls down the
slope or block the wheels to keep the vehicle from
moving. If you do not take either precaution, the
vehicle may roll unexpect edly, leading to a crash.

Refueling
Fuel Information
■Fuel recommendation
Use of lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of gasoline with a pump octane less than 87 can lead to engine damage.
■Top tier detergent gasoline
Because the level of detergency and additi ves in gasoline vary in the market, Acura
endorses the use of “TOP TIER Detergent Gasoline” where available to help
maintain the performance and reliability of your vehicle. TOP TIER Detergent
Gasoline meets a new gasoline standard jointly established by leading automotive
manufacturers to meet the needs of today’s advanced engines.
Qualifying gasoline retailers will, in most cases, identify their gasoline as having met
“TOP TIER Detergent Gasoline” standards at the retail location. This fuel is
guaranteed to contain the proper level of de tergent additives and be free of metallic
additives. The proper level of detergent ad ditives, and absence of harmful metallic
additives in gasoline, help avoid build-up of deposits in your engine and emission
control system.
For further important fuel-related information for your vehicle, or on information on
gasoline that does not contain MMT, visit Acura Owners at owners.acura.com. In
Canada, visit www.acura.ca for additional informati on on gasoline. For more
information on top tier gasoline, visit www.toptiergas.com.
■Fuel tank capacity: 15.1 US gal (57 liters)
Unleaded premium gasoline, pump octane number 91 or higher
1Fuel Information
NOTICE
We recommend quality ga soline 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 reco mmend the use of gasoline
that does NOT contain harmful manganese-based
fuel additives such as MMT, if such gasoline is
available.
Use of gasoline with these additives may adversely
affect performance, a nd cause the malfunction
indicator lamp on your inst rument panel to come on.
If this happens, contact a dealer for service.
Some gasoline today is ble nded with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
by volume. Do not use gaso line containing methanol.
If you notice any undesira ble operating symptoms, try
another service station or sw itch to another brand of
gasoline.

Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2 Emissions
Achieving fuel economy and reducing CO2 emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accord ance with the messages displayed on the
multi-information display.
• Use the recommended viscosit y engine oil, displaying the API Certification Seal.
• Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more
