■Second gear lock mode
If you pull the
(+
paddle shifter while stopped or driving at 6 mph (10 km/h) or less,
the gear position will be locked in 2nd gear. This makes it easier to pull away on
slippery surfaces such as snow covered roads.
To cancel the 2nd gear lock mode, pull the
(-
paddle shifter.
■
Sequential Shift Mode Operation
1 Sequential Shift Mode Operation
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.
Recommended Shift Points
Use this table as a guideline for efficient fuel
economy and effective emission control.
If the gear posit ion 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 indicator is blinking.
In sport mode, to prioritize the engine performance
enhancement, the transmission may not allow for
shifting up while the engine speed is low. Shift Up Normal Acceleration

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Continued
Driving
Tire Pressure Monitoring System (TPMS) - Required Federal ExplanationEach tire, including th e spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Un der-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

RefuelingFuel 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 additives 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 lev el of detergent additives and be free of metallic
additives. The proper level of detergent additives, 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 information on gasoline. For more
information on top tier gasoline, visit www.toptiergas.com.■Fuel tank capacity: 18.5 US gal (70 liters)Unleaded premium gasoline, pump octane number 91 or higher
1Fuel InformationNOTICEWe recommend quality gasoline 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 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, and cause the malfunction
indicator lamp on your instrument panel to come on.
If this happens, contact a dealer for service.
Some gasoline today is blended with oxygenates such
as ethanol. Your vehicle is designed to operate on
oxygenated gasoline containing up to 15% ethanol
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.

uuRefueling uHow to Refuel
Driving
How to RefuelYour fuel tank is not equipped with a fuel fill cap. You can insert the filler nozzle
directly into the filler neck. The tank seals itself again when you pull out the filler
nozzle.
1.Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Turn off the engine.
3. Press the fuel fill door release button.
u The fuel fill door opens.
4. Place the end of the filler nozzle on the
lower part of filler opening, then insert it
slowly and fully.
u Make sure that the end of the filler
nozzle goes down along with the filler
pipe.
u Keep the filler nozzle level.
u When the tank is full, the filler nozzle will
click off automatically.
u After filling, wait about five seconds
before removing the filler nozzle.
5. Shut the fuel fill door by hand.
1How to Refuel
Only a service station filler nozzle can be used.
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel does not overflow as a result
of changes in air temperature.
If the fuel nozzle keeps turning off when the tank is
not full, there may be a problem with the pump’s fuel
vapor recovery system. Try filling at another pump. If
this does not fix the problem, consult a dealer.
Do not continue to add fuel af ter the nozzle has
automatically stopped. Additional fuel can exceed
the full tank capacity.
If you have to refuel your vehicle from a portable
container, use the funnel provided with your vehicle. 2 Refueling From a Portable Fuel Container

Fuel EconomyImproving Fuel EconomyFuel economy depends on several conditions, including driving conditions, your
driving habits, the condition of your vehicle, and loading. Depending on these and
other conditions, you may or 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 accordance with the messages displayed on the
multi-information display.
•Use the recommended viscosity engine oil, displaying the API Certification Seal.
• Maintain the specified tire pressure.

1Engine CoolantNOTICEIf temperatures consistently below -22°F (-30°C) are
expected, the coolant mixture should be changed to
a higher concentration. Consult a dealer for more
information.
If Honda antifreeze/coolant is not available, you may
use another major brand non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda antifreeze/coolant as soon as
possible.
Do not add rust inhibitors or other additives to your
vehicle’s coolant system. They may not be compatible
with the coolant or with the engine components.
