Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode,
the air conditioning compressor, and the fan speed.AUTO will appear on the display next to the fan, mode
indicators, and recirculation indicator if your vehicle
is equipped with the optional air quality sensor.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature setting
will not cause the system to heat or cool any faster.
If you set the system at the warmest temperature
setting, the system will try to continuously heat the
vehicle and will not adjust the system down as the
vehicle warms up.
In cold weather, the system may start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will start out
blowing air at the oor but may change modes,
automatically, as the vehicle warms up to maintain
the chosen temperature setting.
The length of time needed for warm up will depend
on the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary. Vehicles With Heated and Ventilated Seats Shown,

Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airow.
Turn the thumbwheel to the right to open the outlets
completely and allow the maximum amount of air
to enter your vehicle. Turn the thumbwheel to the left to
close the outlets and minimize the amount of air
entering the vehicle.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-55.
Rear Climate Control System
Your vehicle has a rear climate control system. The
base model includes air outlets in the rear of the center
console for cooling and under-seat air outlets for
heating. The temperature, quantity, and air delivery
location is controlled automatically by the front climate
control system.
Some vehicles are equipped with an optional climate
control panel for the rear passenger, located on the back
of the center console.
The left knob controls the temperature of the air to the
rear passengers. Turning the knob to the left will
make the air cooler. Turning the knob to the right will
make the air warmer.
The right knob controls the air delivery to the rear
passengers. Turning the knob all the way to the left will
shut off airow to the rear passengers. Operating
with the rear air delivery off may make the entire vehicle
warm or cool less quickly. It may also increase the air
rush sound of the front system.
