Afterblow Feature
If equipped, under certain conditions, the
fan may stay on or may turn on and off
several times after you turn off and lock the
vehicle. This is normal.
Air Vents
Adjustable air vents are in the centre and on
the sides of the instrument panel, and on
the rear of the centre console storage.
Move the slider knobs to change the
direction of or to close off the airflow.
Operation Tips
Clear away any ice, snow, or leaves from
air inlets at the base of the windscreen
that could block the flow of air into the
vehicle.
Clear snow off the bonnet to improve
visibility and help decrease moisture
drawn into the vehicle.
Keep the path under the front seats clear
of objects to help circulate the air inside
of the vehicle more effectively.
Use of non-GM approved bonnet air flow
deflectors can adversely affect the
performance of the system. Check with
your dealer before adding equipment to
the outside of the vehicle.
Do not attach any devices to the air vent
slats. This restricts airflow and may cause
damage to the air vents.
Maintenance
Passenger Compartment Air Filter
The filter reduces dust, pollen, and other
airborne irritants from outside air that is
pulled into the vehicle. The filter should be
Climate Controls
replaced as part of routine scheduled
maintenance. See your retailer regarding
replacement of the filter.
Service
All vehicles have a label underbonnet that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See your retailer for service.
