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

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.
These keys contain electronic
circuits that are activated by the
Immobilizer System. They will not
work to start the engine if the
circuits are damaged.
Protect the keys f rom direct
sunlight, high temperature, and
high humidity.
Donotdropthekeysorsetheavy
objects on them.
Keep the keys away f rom liquids.
If they get wet, dry them immedi-
ately with a soft cloth.
The keys do not contain batteries.
Do not try to take them apart. Some models also come with two
remote transmitters; see page for
an explanation of their operation.

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.
You can adjust the direction of the
air coming f rom the dashboard vents
by moving the tab in the center of
each vent up-and-down and side-to-
side. 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.
