Do not to cover the sensor located on the top of the
instrument panel near the windshield. This sensor
regulates air temperature based on the intensity of
the sun.
Also do not cover the sensor grille on the lower right
side of the climate control faceplate, as this regulates
the inside temperature.
To avoid blowing cold air at engine start-up in cold
weather, the system delays turning on the fan until
warm air is available. The length of delay depends
on the engine coolant temperature. Turning the fan
knob overrides this delay and changes the fan to
the selected speed.

Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on brie y when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there may
be a problem, check the section that explains what to do.
Follow this manual’s advice. Waiting to do repairs can be
costly and even dangerous.
