3. RecirculationThis function can be used to
shut out exhaust fumes,
smoke, etc from the passen-
ger 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.
TimerThe timer function minimizes the risk of fogging
or stale air when the recirculation function is
selected, see page 81 for information on set-
ting the recirculation timer.
NOTE
If the defroster function is switched on (by
pressing button 4), recirculation is always
disengaged.
Interior Air Quality System (IAQS)*This system consists of a mul-
tifilter that helps reduce gases
and particles in the incoming
air and an air quality sensor
that detects increased levels
of contaminants in the outside
air. When the air quality sen-
sor detects contaminated outside air, the air
intake closes and the air inside the passenger
compartment is recirculated. The filter also
cleans recirculated passenger compartment
air.
When IAQS is engaged, the green indicator
light above A is illuminated.
To activate IAQS:

Press AUTO (1).
Or:
Toggle between the system's three modes by
pressing the button repeatedly.
•IAQS is engaged (the indicator light above
A illuminates).
•Recirculation is engaged (the indicator
light above M illuminates).
•Recirculation is switched off (both indica-
tor lights will be off), unless ECC activates
it to help cool the passenger compartment
faster in hot weather.Keep the following in mind:
•As a rule, IAQS should always be engaged.
•In cold weather, the recirculation function
is limited to help avoid condensation on the
windows.
•If condensation forms, using the defroster
functions for the windshield/front side win-
dows and the rear window will help clear
the condensation.
4. DefrosterDirects airflow to the wind-
shield and side windows and
increases blower speed.
When the defroster is acti-
vated:
•Air flows to the windows at high blower
speed.
•The LED in the defroster button lights up
when this function is activated. The air con-
ditioning system is controlled to provide
maximum air dehumidification.
•The air conditioning is automatically
switched on (can be switched off by press-
ing button 6).
The air is not recirculated.

5. Airflow controlsPress one of the three buttons
in the illustration to activate
the selected airflow. A symbol
in the display above the cli-
mate control panel and a lit
LED in the selected button
indicate that the manual func-
tion has been selected. With manually selected
airflow both warm and cool air can be selected.
See also the table on page 95.
6. Air conditioning On/OffON: The air conditioning sys-
tem is engaged when the ON
light is lit and is controlled
automatically by the system
to maintain the selected tem-
perature.
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.
Other functions are still controlled automati-
cally.
When Defroster (4) is selected, the air condi-
tioning system is activated for maximum dehu-
midifying.
7 and 8. Heated front seats*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 win-
dow and door mirrors.
The rear window and door
mirrors are defrosted simulta-
neously if the switch is
pressed once. The defrost
function is active if the LED in the switch is illu-
minated.
•The function can be switched off manually
by pressing the button.
•The defrost function switches off automat-
ically after 12–20 minutes, depending on
the outside temperature.
NOTE
•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.
•This function is automatically switched
off when the power retractable hard top
is down.
10. Temperature selectorThe temperatures on the driv-
er's and passenger's sides
can be set separately using
the knob (with the thermome-
ter 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:
1. Press the knob once. The LED for one side
of the car will light up. Turn the knob to
adjust the temperature.
2. Press the knob a second time to set the
temperature on the opposite side of the
car.

3. Press the knob a third time to set the tem-
perature 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.
Sensors
•The sunlight sensor is on the upper side of
the dashboard
•The passenger compartment temperature
sensor is located behind the climate sys-
tem control panel.
•The ambient temperature sensor is in the
driver's side door mirror.
•The humidity sensor is in the rearview mir-
ror.
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 compart-
ment.
AccelerationThe air conditioning system is temporarily
switched off during full throttle acceleration.

Uniform tire quality gradings

187 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 appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA
Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire gra-
ded 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 signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-faces of asphalt and concrete. A tire marked C
may have poor traction performance. The trac-
tion 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.
TEMPERATUREThe temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a minimum level of performance that all pas-
senger vehicle tires must meet under the Fed-
eral Motor Safety Standard No. 109. Grades B
and A represent higher levels of performance
on the laboratory test wheel than the minimum
required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.
