Climate Controls

and ventilation for your vehicle.

delivery mode and the fan speed.
3-24
1. Press the AUTO button.
2. Adjust the temperature to 75° F (24° 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 remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will 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 floor 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.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see "Sensors" later in
this section.
