Reporting Safety Defects
In the U.S.
If you believe that your vehicle has a defect which could cause a crash or could
cause injury or death, you should immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to notifying American Honda Motor
Co., Inc.
If NHTSA receives similar complaints, it may open an investigation, and if it finds
that a safety defect exists in a group of vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot become involved in individual problems
between you, your dealer, or American Honda Motor Co., Inc.
To contact NHTSA, you may call the Vehicle Safety Hotline toll-free at (888)
327-4236 (TTY: 1-800-424-9153); go to http://www.safercar.gov;  or write to:
Administrator, NHTSA, 1200 New Jersey Avenue, SE., Washington, DC 20590. You
can also obtain other information about motor vehicle safety from http://www.
safercar.gov.
In Canada
If you believe that your vehicle has a defect which could cause a crash or could
cause injury or death, you should immediately inform Honda Canada, Inc., and you
may also inform Transport Canada.
If Transport Canada receives similar complaints, it may open an investigation, and
if it finds that a safety defect exists in a group of vehicles, it may lead to a recall
and remedy campaign. However, Transport Canada cannot become involved in
individual problems between you, your dealer, or Honda Canada, Inc.
To contact Transport Canada’s Defect Investigations and Recalls Division, you may
call (800) 333-0510. For more information on reporting safety defects or about
motor vehicle safety, go to http://www.tc.gc.ca/roadsafety. Learn about the indicators, gauges, and displays related to driving the vehicle.
Indicators briefly appear 
with each engine start and  then go out. Red and amber 
indicators are most critical. Blue and green indicators are used for general
information.
Malfunction Indicators
These are the most critical indicators. If they come on and stay lit while driving or
at any other time, there may be a problem. See your dealer if necessary.
Brake system
• Brake  fluid is low.
•  There is a malfunction in the brake system.
Press the brake pedal lightly to check pedal pressure. If normal, check
the brake  fluid level  when you stop. If abnormal,  take immediate action. 
If necessary, downshift the transmission to slow the vehicle using engine
braking. Have your vehicle repaired immediately.
Low oil pressure
Engine oil pressure is low. Stop in a safe place. Open the hood and check
the oil level, and add oil if necessary. If the indicator does not turn off, have
your vehicle repaired immediately.
Malfunction indicator lamp (check engine light)
•  The emissions control system may have a problem, or the fuel cap is
missing or loose.
•  (Blinks) A misfire in the engine’s cylinders is detected. Stop in a safe place,
and wait for the engine to cool down.
Charging system
The battery is not charging. Turn off all electrical items, but do not turn off
the vehicle to prevent further battery discharge. Have your vehicle repaired
immediately.

How to Refuel
1. The fuel fill door is located at the left rear of the
vehicle. Park next to the service pump that is
most accessible.
2. Turn off the engine.
3. Pull the fuel fill door release handle near the
parking brake. The fuel fill door opens.
4. Turn the fuel fill cap slowly to open. Place the
fuel fill cap in the holder.
5. Insert the filler nozzle fully. When the tank is full,
the fuel nozzle clicks off automatically.
6. Replace the fuel fill cap. Tighten it until you hear
at least one click. Close the fuel fill door.
Refueling
Use the proper fuel and refueling procedure to ensure the best performance and
safety of your vehicle.
Fuel Information
Use of unleaded gasoline of 91 octane or higher is recommended.
•  Acura recommends TOP TIER Detergent Gasoline where available.
•  Do NOT use gasoline containing more than 15% ethanol.
•  Do NOT use gasoline containing methanol.
•  Do NOT use gasoline containing MMT.
We 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.
NOTICE
Gasoline is highly  flammable and explosive.  You can be burned or seriously injured 
when handling fuel.
•  Stop  the engine, and keep heat, sparks, and  flame away.
•  Handle fuel only outdoors.
•  Wipe up spills immediately.

Keyless Access Remote Battery Strength
If the battery life in your keyless access remote is weak, a message appears in the
multi-information display (MID) with information on how to start the engine.
1. Touch the back of the keyless access remote to the
ENGINE START/STOP button while the indicator
is flashing.
2. With the brake pedal pressed, press the ENGINE
START/STOP button within 10 seconds.
Jump Starting
Turn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood.
1. Connect the first jumper cable to your vehicle’s
battery (+) terminal.
2. Connect the other end of the first jumper cable
to the booster battery (+) terminal. Use a 12-volt
booster battery only.
3. Connect the second jumper cable to the booster
battery (-) terminal.
4. Connect the other end of the second jumper cable
to the engine hanger as shown. Do not connect
this jumper cable to any other part.
5. If your vehicle is connected to another vehicle,
start the assisting vehicle’s engine and increase its
rpm slightly.
6. Attempt to start your vehicle’s engine. If it turns over slowly, make sure the
jumper cables have good metal-to-metal contact.
WARNING: Battery posts, terminals, and related accessories contain lead and
lead compounds. Wash your hands after handling.

U.S. models
Maintenance, replacement, or repair of emissions control devices and systems
may be done by any automotive repair establishment or individuals using
parts that are certified to EPA standards.
According to state and federal regulations, failure to perform maintenance on the
maintenance main items marked with # will not void your emissions warranties.
However, all maintenance services should be performed in accordance with the
intervals indicated by the multi-information display.
Under the Hood
Opening the Hood
1. Park the vehicle on a level surface, and set the
parking brake.
2. Pull the hood release handle under the lower left
corner of the dashboard.
3. Push up the hood latch lever in the center of the
hood to release the lock mechanism, and open
the hood.
4. Remove the support rod from the clamp using
the grip. Mount the support rod in the hood.
When closing, remove the support rod, and stow
it in the clamp, then gently lower the hood.
Remove your hand at a height of approximately
12 inches (30 cm) and let the hood close.
Do not open the hood when the wiper arms are raised. The hood will strike the

Frequently Asked Questions/Troubleshooting
Below are some frequently asked questions and troubleshooting items that you
may have about the vehicle.
Q: How  do I set the vehicle clock?
A: For vehicles without navigation, see page 44. For vehicles with navigation, the
time is automatically set using GPS signals.
Q: Why  doesn’t the vehicle start  when I press the ENGINE START/STOP button?
A: The brake pedal must be pressed to start the engine.
Q: What is  the AUTO setting  on my headlight lever? 
A: When in the AUTO position, the vehicle’s exterior lights will automatically turn
on or off depending on the ambient lighting.
Q: Only  the driver’s  door unlocks  when I shift to Park (P). Can  all doors unlock? 
A: You can change door lock or unlock settings in the multi-information display
using the Customize Settings menus. See page 27.
Q: Why  won’t the driver’s  door unlock  when I grab the door handle,  even though  the 
keyless  access remote is  within range?
A: If you pull the handle too quickly, the system may not have time to confirm the
door is unlocked. Wait to hear a beep to confirm the door is unlocked. If you are
wearing gloves, the system may be slow to respond.
Q: After my battery  was disconnected  or went  dead,  the  audio system is  asking for a 
code.  Where  do I find  this?
A: In most cases, you do not need to enter a code. Turn on the vehicle and the audio
system, and press and hold the power button until the system reactivates.
Q: Why can’t I  operate Pandora  through the audio system?
A: Audio may be streaming through Bluetooth® Audio. Make sure Pandora mode is
selected and the phone cable is properly connected to the USB adapter. Some
phones may prompt you to “Allow” a connection.
Q: Is my phone compatible  with Bluetooth features?
A: Visit www.acura.com/handsfreelink (U.S) or www.handsfreelink.ca (Canada) to
check phone compatibility for Bluetooth® Audio, Bluetooth® HandsFreeLink®,
and SMS text messaging.
