The Immobilizer System protects
your vehicle f rom thef t. A properly-
coded master or valet key must be
used in the ignition switch f or the
engine to start. If an improperly-
coded key (or other device) is used,
the engine’s f uel system is disabled.
When you turn the ignition switch to
ON (II), the Immobilizer System
indicator should come on f or a f ew
seconds, then go out. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to
LOCK (0), remove the key, reinsert
it, and turn the switch to ON (II)
again.The system may not recognize your
key’s coding if another immobilizer
key or other metal object is near the
ignition switch when you insert the
key. To make sure the system
recognizes the key code:
Do not keep other immobilizer
keys on the same key ring.
Use a plastic or leather key f ob,
not metal.
Keep other keys away f rom your
vehicle’s key and the ignition
switch while trying to start the
engine. If the system repeatedly does not
recognize the coding of your key,
contact your Acura dealer.
The Immobilizer System indicator
will also blink several times when
you turn the ignition switch f rom ON
(II) to ACCESSORY (I) or LOCK (0).
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle undriveable.
If you have lost your key and you
cannot start the engine, contact your
Acura dealer.

Both f ront seats are equipped with
seat heaters. The ignition switch
must be ON (II) to use them. Push
the front of the switch, HI, to rapidly
heat up the seat. After the seat
reaches a comf ortable temperature,
select LO by pushing the back of the
switch. This will keep the seat warm.Follow these precautions whenever
you use the seat heaters:
Use the HI setting only to heat the
seats quickly. Select the LO
setting when the seats f eel warm.
The HI setting draws large
amounts of current f rom the
battery.
Do not use the seat heaters, even
on the LO setting, if the engine is
lef t idling f or an extended period.
They can weaken the battery,
causing hard starting.
The HI or LO indicator lights and
remains lit until you turn it of f by
pushing the opposite side of the
switch lightly. The indicator will turn
off.
In HI, the heater turns of f when the
seat gets warm, and turns back on
after the seat’s temperature drops. It
continues to cycle as long as you
leave it set on HI. The HI indicator
remains lit as a reminder that you
have the heater on.
In LO, the heater runs continuously.
It does not cycle with temperature
changes.
Because of the sensors f or the side
airbag system, there is no heater in
the passenger’s seat-back.

For the climate control system to
provide heating and cooling, the
engine must be running.
The automatic climate control
system in your Acura picks the
proper combination of air condi-
tioning, heating, and ventilation to
maintain the interior temperature
you select. The system also adjusts
the fan speed and air flow levels.
Your vehicle also has a rear A/C unit
that allows the rear passengers to
adjust the heating, cooling, and air
f low (see page ).
The direction of air f low f rom the
vents in the center and each corner
of the dashboard is adjustable.
Move the tab in the center of each
vent up-and-down and side-to-side.
The vents in the corners of the
dashboard can be opened and closed
with the dials underneath them.
The climate control system draws air
through the exterior vents at the
bottom of the windshield. Keep
these vents clear of leaves and other
debris.

Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Avoid full-throttle starts and rapid
acceleration. Youshouldfollowthesesamere-
commendations with an overhauled
or exchanged engine, or when the
brakes are replaced.
Do not change the oil until the
recommended time or mileage
intervalshowninthemaintenance
schedule.
Avoidhardbraking.Newbrakes
need to be broken-in by moderate
use f or the f irst 200 miles (300
km). Your Acura is designed to operate on
premium unleaded gasoline with a
pump octane number of 91 or higher.
Use of a lower octane gasoline can
cause occasional, metallic knocking
noises in the engine and will result in
decreased engine perf ormance.
We recommend gasolines containing
detergent additives that help prevent
f uel system and engine deposits.
Using gasoline containing lead will
damage your vehicle’s emissions
controls. This contributes to air
pollution.
We also recommend that you do not
tow a trailer during the f irst 500
miles (800 km).

Because the f uel f ill cap is on the
driver’s side of the vehicle, park
with that side closest to the
service station pumps.
Open the f uel f ill door by pulling
onthehandletotheleftof the
driver’s seat.
In Canada, some gasolines contain
an octane-enhancing additive called
MMT. If you use such gasolines,
your emissions control system
perf ormance may deteriorate and
the Malf unction Indicator Lamp on
your instrument panel may turn on.
If this happens, contact your
authorized Acura dealer f or service.
