This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise
from the bottom white mark to about
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the pointer may rise to the
upper zone. If it reaches the red
(Hot) mark, pull saf ely to the side of
the road. Turn to page for

Some models also come with two
remote transmitters; see page for
an explanation of their operation.The Immobilizer System protects
your car 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
car’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 Honda dealer.

This section covers how to set up the
system controls f or ventilation,
heating, cooling, dehumidif ying, and
def rosting.
The engine must be running f or the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes bef ore you f eel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.
The vents in the corners of the
dashboard can be opened and closed
with the dials underneath them.
The direction of air f low f rom the
vents in the center and each side of
the dashboard is adjustable.
To adjust the air flow from each vent,
move the vent up-and-down and
move the tab side-to-side.
