CLIMATE CONTROL –
TROUBLESHOOTING
Climate Control – Frequently
Asked Questions
Why is the volume of air to the rear
passenger compartment limited?
Objects may obstruct the air direction
to the rear passenger compartment.
Make sure objects have not been
placed under the front seats.
Why is the volume of air from the air
vents reduced? The air intake area at the base of the
windshield could be obstructed. Make
sure the air intake area is free from any
snow, ice or leaves.
What are the recommended settings
for heating the interior? A medium blower motor speed
selected and the air directed to the
footwell and windshield air vents.
How can I quickly heat the interior? Select the highest blower motor
speed, highest temperature and direct
the air to the footwell air vents.
What are the recommended settings
for cooling the interior? Air conditioning on, a medium blower
motor speed selected and air directed
to the footwell and windshield air
vents.
How can I quickly cool the interior? Switch maximum cooling on, switch
recirculated air on and drive with the
windows open until you feel cold air
through the air vents. How can I reduce the humidity build-up
inside my vehicle?
Do not drive with the system off or
with recirculated air on.
How can I defog the side windows? Switch maximum defrost on.
How can I defog or clear the windshield
of thin ice? Switch maximum defrost on.
Why do I feel air from the footwell air
vents regardless of the air
distribution? This is normal operation. You may feel
a small amount of air from the
footwell air vents regardless of the air
distribution.

seats may also turn on when you start your
vehicle if they were on when you switched
your vehicle off.
Do not do the following:
• Spill liquid on the front seats. This may
cause the air vent holes to become
blocked and not work properly.
• Place cargo or objects under the seats.
They may block the air intake causing
the air vents to not work properly.
The engine must be running to use this
feature. Press this symbol to cycle through the
various ventilation settings and off. More
indicator lights indicate higher fan speeds.
If the engine falls below 350 RPM while
the ventilated seats are on, the feature

To improve comfort, use the
ventilated seats along with the vehicle ’s air
conditioning system.
