A Typical Cold Weather Example: Your vehicle has been parked outside ~ v e r ~ ~ iin h t g cold weather (below 32 OF/ 0"C) and you have set the driver temperature at 73 O (23 "C) and have selected F the AUTO mode. The system will automatically adjust the temperature output to maximum heating. The fan will start at a low speed. This is to avoid blowing cold air into the vehicle. The length of the delay depends on the amount of time since the engine was last started, the outside temperature and the engine coolant temperature. As the coolant warms up, the fan speed will gradually increase. Air will flow to the floor with some air to the windshield to prevent fogging under most normal conditions. As the interior of the vehicle warms up to your comfort set temperature, the fan speed will decrease and the temperature output may become cooler. If the interior temperature continues to warm up due to heatingfrom the sun or outside temperature increases, the system may switch to other air delivery modes (typically DEFOG or BI-LEVEL). A vpical Hot Weather Example: Your vehicle has Seen parked outside all day in hot weather (above 70 O F / 2 1 C) and you have set the driver temperature at 73"F (23 C ) and have selected O O the AUTO mode. The system will automatically adjust the temperature output tomaximum cooling. Theblower will start at a low speed momentarily to push the hot air to the floor of the vehicleand then go to a higher blower speed with cold airflow out of the instrument panel outlets.A small amount of airflow will continue through the lower ducts tocool the floor area. The air intake may start in the recirculated mode for maximum cooling performance. As the interior of the vehicle cools down to your comfort set temperature, the fanspeed will decrease and the temperature output may become warmer. The airintake may shift from recirculation to fresh air mode. If the interior continues to cooldue to a decrease in the amount of heat the vehicle is absorbing from the sun or a decrease in the outside temperature, the system could switch to other air delivery modes (typically BI-LEVEL or DEFOG). 3-7

A
Typical
Cold
Weather
Example:
Your
vehicle
has
been
parked
outside
~ v e r ~ ~ i g h t
in
cold weather (below 32 OF/
0"
C)
and you have set
the driver temperature at 73 OF
(23
"C)
and have selected
the
AUTO mode. The system will automatically adjust
the temperature output to maximum heating. The
fan
will start at a low speed. This
is
to avoid blowing cold
air into the vehicle. The length of the delay depends
on the amount of time since the engine was last started,
the outside temperature and the engine
coolant
temperature. As the coolant warms up, the fan speed
will gradually increase. Air will flow to the floor with
some air to the windshield to prevent fogging under
most normal conditions.
As the interior
of
the vehicle warms up
to
your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler. If the
interior
temperature continues to warm
up due to
heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically
DEFOG or BI-LEVEL).
A
vpical
Hot
Weather
Example:
Your
vehicle
has
Seen
parked outside all day in
hot
weather (above
70
O F /
2
1
O
C)
and you have
set
the
driver temperature at
73
"F
(23
O
C )
and have
selected
the AUTO mode. The system will automatically
adjust
the temperature output
to maximum cooling.
The blower
will start at a low speed momentarily to push the
hot
air to the floor of the
vehicle and then
go
to a higher
blower speed with cold airflow out of the
instrument
panel
outlets. A small amount of airflow will continue
through the lower ducts
to cool the floor
area.
The air intake may start
in
the
recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to your comfort set
temperature,
the
fan speed will decrease and the temperature
output
may become warmer. The
airintake may shift
from
recirculation to
fresh
air mode.
If
the interior
continues
to
cool due to a decrease
in
the
amount
of
heat the
vehicle is absorbing from the sun or a decrease
in
the
outside temperature, the system could
switch
to
other
air
delivery modes (typically BI-LEVEL or DEFOG).
