OVERVIEW
The climate control system incorporates the heating, ventilation and A/C (air conditioning) systems. There are 2 main types of climate control system available:
The climate control functions for both systems are controlled by the ATC (automatic temperature control) module. The ATC module is mounted in the center console and contains both the system electronic software and user controls.
The ATC module works in conjunction with a number of other vehicle control modules, including the ECM (engine control module), which controls a number of climate control sub-systems on receipt of requests from the ATC module.
The dual zone climate control system features automatic control of air temperature, air distribution and blower motor speed. The ATC module is also able to control individual temperature requests for both the driver and passenger side of the cabin.
NOTE: The ATC module can only maintain a maximum temperature difference
between the 2 sides of the cabin of up
to approximately 3READ NEXT:

When setting the cruise
control to the
speed limit, it is important to remember
that it is possible for the vehicle speed
to increase when travelling downhill.
This may result in the vehicle speed
exceeding the speed limit.
Note: Cruise control can be engaged only at
speeds in excess of 30
Set or increase cruise speed
