The immobilizer system protects
your vehicle from theft. If an
improperly coded key (or other
device) is used, the engine's fuel
system is disabled.
When you turn the ignition switch to
the ON (II) position, the immobilizer
system indicator should come on
briefly, then go off. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to the
LOCK (0) position, remove the key,
reinsert it, and turn the ignition
switch to the ON (II) position again.The system may not recognize your
key's coding if another immobilizer
key or other metal object (i.e. key
chain) is near the ignition switch
when you insert the key.
If the system repeatedly does not
recognize the coding of your key,
contact your dealer.
Do not attempt to alter this system or
add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.
If you have lost your key and cannot
start the engine, contact your dealer.
Always take the ignition key with you
whenever you leave the vehicle alone.

The ignition switch has four
positions: LOCK (0), ACCESSORY
(I), ON (II), and START (III).
LOCK (0)-You can insert or
remove the key only in this position.
To turn the key, the shift lever must
be in Park, and you must push the
key in slightly. If the front wheels are turned, the
anti-theft lock may make it difficult to
turn the key. Firmly turn the steering
wheel to the left or right as you turn
the key.
ACCESSORY (I)
-You can operate
the audio system and the accessory
power sockets in this position.
ON (II) -This is the normal key
position when driving. Several of the
indicators on the instrument panel
come on as a test when you turn the
ignition switch from the
ACCESSORY (I) to the ON (II)
position.
START (III) -Use this position
only to start the engine. The switch
returns to the ON (II) position when
you let go of the key. You will hear a reminder beeper if
you leave the key in the ignition
switch in the LOCK (0) or the
ACCESSORY (I) position and open
the driver's door. Remove the key to
turn off the beeper.
You will also see a
‘‘REMOVE KEY ’’
message on the multi-information
display (see page 80).
The shift lever must be in Park
before you can remove the key from
the ignition switch.

Both front seats are equipped with
seat heaters. The passenger seat is
only heated in the seat bottom
because of the side airbag cutoff
system.
The ignition switch must be in the
ON (II) position to use seat heaters.
Push the top of the switch, HI, to
rapidly heat up the seat. After the
seat reaches a comfortable
temperature, select LO by pushing
the bottom of the switch. This will
keep the seat warm.In the HI setting, the heater turns off
when the seat gets warm, and turns
back on after the seat's temperature
drops.
In the LO setting, the heater runs
continuously. It does not cycle with
temperature changes.
Follow these precautions whenever
you use the seat heaters:
●Use the HI setting only to heat the
seats quickly, because it draws
large amounts of current from the
battery.●If the engine is left idling for an
extended period, do not use the
seat heaters, even on the LO
setting. It can weaken the battery,
causing hard starting.

Proper use of the climate control
system can make the interior dry and
comfortable, and keep the windows
clear for best visibility.
For the climate control system to
provide heating and cooling, the
engine must be running.
You can adjust the temperatures of
the driver's side and the passenger's
side independently (see page 169).
Voice Control SystemOn models with navigation systemThe climate control system can also
be operated by voice control. See the
navigation system manual for
complete details.Using Automatic Climate Control
The automatic climate control system
adjusts the fan speed and airflow
levels to maintain the interior
temperature you select.
On models with navigation systemIn AUTO mode, the vehicle's interior
temperature is independently
regulated for the driver and
passenger, based on inputs from
sunlight and temperature sensors
(see page 171). If one side of the
vehicle is getting too much sun, the
system lowers the temperature only
on that side.
1. Press the AUTO button. The
indicator in the button comes on. 2. Set the desired temperature by
pushing the driver's side
temperature control buttons (
or
). The selected temperature will
show in the display.
When you push the passenger's side
temperature control buttons, the
indicator in the DUAL button comes
on and the driver's side and
passenger's side temperature can be
controlled independently (see page
169).
The system automatically selects the
proper mix of conditioned and/or
heated air that will, as quickly as
possible, raise or lower the interior
temperature to your preference.

If the engine has just been started, it
may take a short time for the system
to display the rearview.
The camera display brightness is
adjusted automatically by sensors. If
you use the camera display
continuously at high temperature,
the image will gradually dim and
eventually turn off automatically. If
you change to another shift position,
the camera display will come on
again when you return to reverse.
The inside mirror will be hot when
you use the monitor for an extended
period of time.
If a bright light (such as sunlight) is
reflected on the mirror, the image
may be difficult to see.
Rearview Camera Guide Line
The camera display has parking
guide lines that indicate distance
from your vehicle.
1st Line 24in (0.6m)
2nd Line 39in (1m)
3rd Line 79in (2m)
4th Line 118in (3m)
NOTE●The rearview camera has a unique
lens that makes objects appear
closer than they actually are.●The rearview camera display has a
limited coverage, and the size and
position of objects may appear
different than they actually are.
Make sure to check the
surrounding area carefully.
To turn the guide line on and off,
hold the power button for more than
3 seconds when the shift is in
reverse, the on/off setting will be
kept when you change gear and
return to reverse.

Before you begin driving your
vehicle, you should know what
gasoline to use and how to check the
levels of important fluids. You also
need to know how to properly store
luggage or packages. The
information in this section will help
you. If you plan to add any
accessories to your vehicle, please

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
scheduled maintenance time.●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.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.We recommend using 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 authorized 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 atowners.acura.comIn Canada, visit
www.acura.ca
for
additional information on gasoline. Refueling
1. Park with the driver's side closest
to the service station pump.
2. Open the fuel fill door by pulling on the handle at the outside of the
driver's seat.
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.
