NOTE
The sunlight sensor on the upper side of the dashboard and the passenger compartment temperature sensor, located
behind the climate system control panel, should not be obstructed.

ECC functions
1. Auto - On/Off
The AUTO function automatically regulates climate control to maintain the desired temperature. The automatic
function controls heating, air conditioning, blower speed, recirculation, and air distribution.
If you select one or more manual functions, the remaining functions continue to be controlled automatically. All
manual settings are
83 03 Climate
Electronic Climate Control (ECC)
switched off when AUTO is switched on. AUTO CLIMATE is shown in the display.
2. Blower speed
The blower speed can be increased or decreased by turning the knob. The blower speed is regulated automatically if
AUTO is selected. The previously set blower speed is disconnected.
NOTE
If the knob is turned counterclockwise and the blower indication in the display goes out, the blower and the air
conditioning are switched off. The display shows the blower symbol and OFF.
3. Recirculation
This function can be used to shut out exhaust fumes, smoke, etc from the passenger compartment. The air in the
passenger compartment is then recirculated, i.e. no air from outside the car is taken into the car when this function is
activated.
If the air in the car recirculates for too long, there is a risk of condensation forming on the insides of the windows,

especially in winter.
Timer
The timer function minimizes the risk of fogging, or stale air when the recirculation function is selected. See page 72
for information on setting the recirculation timer.
NOTE
Recirculation is always disengaged if the defroster button is engaged to clear ice or condensation from the side
windows.
4. Defroster
Directs airflow to the windshield and side windows and increases blower speed.
When the defroster is activated:
Air flows to the windows at high blower speed.
The LED in the defroster button lights up when this function is activated. The air conditioning system is controlled
to provide maximum air dehumidification.
The air conditioning is automatically switched on (can be switched off by pressing button 5).
The air is not recirculated.
5. Airflow controls
Press one of the three buttons in the illustration to activate the selected airflow. A symbol in the display above the
climate control panel and a lit LED in the selected button indicate that the manual function has been selected. With
manually selected airflow both warm and cool air can be selected. See also the table on page 86
.
6. Air conditioning On/Off
ON: The air conditioning system is engaged when the ON light is lit and is controlled automatically by the system to
maintain the selected temperature.
OFF: The system is disengaged when the OFF lights up
When OFF is selected and the OFF LED is lit, the air conditioning system is deactivated.
84 03 Climate

Other functions are still controlled automatically.
When Defroster (4) is selected, the air conditioning system is activated for maximum dehumidifying.

7 and 8. Heated front seats (option)
Maximum heating : Press the button once - both LEDs light up.
Reduced heating : Press the button a second time - one LED lights up.
Seat heating off : Press the button a third time - no LEDs are lit.
9. Rear window and door mirror defrosters
Press to defrost the rear window and door mirrors.
The rear window and door mirrors are defrosted simultaneously if the switch is pressed once. The defrost function is
active if the LED in the switch is illuminated.
The function can be switched off manually by pressing the button.
The defrost function switches off automatically after 12-20 minutes, depending on the outside temperature.
NOTE
This function is automatically switched off when the power retractable hard top is down.
On certain markets, the defrost function may remain on longer than 20 minutes in cold weather to help keep the
rear window free from ice or condensation.
10. Temperature selector
The temperatures on the driver's and passenger's sides can be set separately using the knob (with the thermometer in
it). The temperature can be set for both sides of the car when the ignition is switched on (both LEDs will be on), which
means that a temperature setting will apply to both sides of the car.
To set the temperature on one side of the car:
Press the knob once. The LED for one side of the car will light up. Turn the knob to adjust the temperature.
Press the knob a second time to set the temperature on the opposite side of the car.
Press the knob a third time to set the temperature on both sides of the car at the same time.
NOTE
Selecting a temperature that is higher or lower than necessary will not heat or cool the passenger compartment faster.

Electronic Climate Control (ECC)
ECC sensors
The sunlight sensor is on the upper side of the dashboard
ProCarManuals.com

The passenger compartment temperature sensor is located behind the climate system control panel.
The ambient temperature sensor is in the driver's side door mirror.
The humidity sensor is in the rearview mirror.
These sensors should never be obstructed.
NOTE
The sunlight sensor monitors the side of the vehicle from which the sun shines into the passenger compartment. This
means that the temperature may differ slightly between the left and right air vents, even if the climate system
temperature is set to be the same for both sides of the passenger compartment.

WARNING
Exceeding the permissible axle weight, gross vehicle weight, or any other weight rating limits can cause tire
overheating resulting in permanent deformation or catastrophic failure.
Do not use replacement tires with lower load carrying capacities than the tires that were original equipment on the
vehicle because this will lower the vehicle's GVW rating. Replacement tires with a higher limit than the originals do
not increase the vehicle's GVW rating limitations.

Uniform tire quality gradings
Uniform tire quality gradings
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would wear one and one half (1 1/2) times as well on the government course as a tire
graded 100.
The relative performance of tires depends upon the actual conditions of their use, however, and many depart
significantly from the norm due to variation in driving habits, maintenance practices and differences in road
characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of
cornering (turning) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of
cornering (turning) traction.
