Switching the ZONE function on/off
This function is only available with automatic
climate control.
To activate:press the
button. The indi-
cator light in thebutton lights up. The
temperature setting for the driver’s side is not
adopted for the front-passenger side.
To deactivate: press the
button. The
indicator lamp in thebutton goes out.

Defogging the windshield
You can use this function to de-ice the wind-
shield or to defog the inside of the windshield
and the side windows.
NOTE
You should only select the Windshield demist-
ing function until the windshield is clear again.
Activating the Windshield demisting function
:
Make sure the ignition switch is in the ON
position.
To activate: press the
button The indica-
tor light in thebutton lights up. The climate control system switches to the
following functions:
•High airflow
•High temperature
•Air distribution to the windshield and front
side windows
•Air-recirculation mode off
NOTE
•The Windshield demisting function auto-
matically sets the blower output to the opti-
mum demisting effect. As a result, the airflow
may increase or decrease automatically after
the
button is pressed.
•You can adjust the blower output manually
while the Windshield demisting function is
in operation. Press the
orbutton.
Deactivating the Windshield demisting func-
tion
:
Press thebutton. The indicator lamp in
thebutton goes out. The previous set-
tings are reactivated Air-recirculation mode re-
mains deactivated.

Defogging the windows
Windows misted up on the inside:
1. Activate theCooling with air dehu-
midification function.
2. Activate automatic mode
.
3. If the windows continue to mist up, activate the
Windshield demisting function.
NOTE
You should only select this setting until the
windshield is clear again.
Windows misted up on the outside
:
1. Activate the windshield wipers.
2. Set the air distribution to

You should only select this setting until the win-
dows are clear again.
Air recirculation mode
You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle from
outside. The air already inside the vehicle will
then be recirculated.

DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable
on the tire sidewall between 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 gov-
ernment 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 actual conditions of their use,
however, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteristics
and climate.
TRACTION AA, A, B AND C
The traction grades, from highest to lowest, are
AA, A, B and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C
The temperature grades 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 ma-
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A rep-
resent higher levels of performance on the
laboratory test wheel than the minimum re-
quired 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 separately or in
combination, can cause heat build-up and pos-
sible tire failure.
