is engaged.
•Blower speed increases automatically and
the air conditioning will switch on (if not
already on and if the passenger compart-
ment blower is not turned off) to dehumid-
ify the air in the passenger compartment.
•Recirculation will not function while defrost
is engaged.
The climate system will return to its previous
settings when the defroster function is
switched off.
Rear window and door mirror
defrosters
This function defrosts/deices the rear window
and door mirrors. The LED in the switch will
light up to indicate that the heating function is
engaged. For additional information on this
function see page 75.
Never use ice scrapers made of metal as they
can easily scratch the mirror surface.
Heated front seats*
1. Press the switch once for maximum seat
heating. Both LEDs in the switch will be lit.
2. Press the switch a second time for comfort
heating. One LED in the switch will be lit.3. Press the switch a third time to turn the
heating off completely. The LED will go off.
The seat heating for the passenger seat should
be switched off when the seat is not occupied.

Button for rear seat heating
Heating for the respective outboard rear seats
can be switched on or off with buttons on either
side of the center console (see the illustration).
To switch on rear seat heating:
–Press the button.
> The symbol in the button will illuminate.To switch off rear seat heating:
–Press the button.
> The symbol in the button will go out.
Temperature
These controls are used to individually set the
temperature for both sides of the passenger
compartment. Please note that the compart-
ment will not be heated or cooled faster by set-
ting the temperature higher or lower than nec-
essary.
Set the control to the temperature you prefer.
Blower control1
Turn the control clockwise to increase or coun-
terclockwise to decrease the blower speed.
Pressing the AUTO switch will automatically
regulate blower speed and override manual
adjustment.
Turning the blower control counterclockwise
until an orange LED comes on will turn both the
blower and the air conditioning off.
Blower control for rear climate

or:
Select one of the following three functions by
pressing 1, 2 or 3 times.
1.
The AUT LED lights. The air quality sensor
is now activated.
2. No LED lights. Recirculation is not acti-
vated unless needed to cool the passenger
compartment in a warm climate.
3.
The MAN LED lights. Recirculation is now
activated.
Keep in mind the following:
•Make it a rule to have the air quality sensor
activated at all times.
•Recirculation is limited in cold climates to
avoid fogging.
•If window fogging occurs, you should
deactivate the air quality sensor. Also use
the defroster functions for the windshield,
side windows and rear window, see
page 98.
•The filter should be changed at the inter-
vals recommended in the service sched-
ule. However, if the vehicle is used in a
severely contaminated environment, it may
be necessary to change the filter more fre-
quently.

07 Wheels and tires
Uniform Tire Quality Grading
07
186
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.
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.

Fuses are located inside the access panel on
the edge of the dashboard, on the driver's side.
There are also a number of spare fuses. When
replacing a blown fuse, be sure to replace it
with a new one of the same color and amper-
age (written on the fuse).
