TimerThe timer function minimizes the risk of mist-
ing, or stale air when the recirculation function
is selected, see page 85 for information on set-
ting the recirculation timer. Recirculation is
always disengaged when you select
Defroster (3).
3. DefrosterDirects airflow to the wind-
shield 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 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 5).
4. 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.
The desired temperature is selected using con-
trol 9.
5. A/C – On or OffON: The air conditioning sys-
tem is engaged when the ON
light is lit.
OFF: The system is disen-
gaged when the OFF lights
up.
If Defroster (3) is activated the air conditioning
is always engaged.
6/7. 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.
8. Heated rear window and door mirrorsPress 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.

acceleration.
ECC functions
1. Auto – On/OffThe AUTO function automat-
ically regulates climate con-
trol to maintain the desired
temperature. The automatic
function controls heating, air
conditioning, blower speed,
recirculation, and air distribu-
tion.
If you select one or more manual functions, the
remaining functions continue to be controlled
automatically. All manual settings are switched
off when AUTO is switched on.

2. Blower speedThe blower speed can be
increased or decreased by
turning the knob. The blower
speed is regulated automati-
cally 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. 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 85 for information on set-
ting the recirculation timer.
NOTE
Recirculation is always disengaged if the
defroster button is engaged to clear ice or
condensation from the side windows.
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 102.
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.

9. Rear window and door mirror
defrosters

Press to defrost the rear window and door
mirrors.
The rear window and door mirrors are defros-
ted simultaneously if the switch is pressedonce. 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 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.
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.

07 Wheels and tires
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 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.
