153 Adjusting air volume
You can adjust the air volume using air volume
control
1. Five blower speeds are available.
The air volume is controlled depending on the
blower speed selected.

Air recirculation modeSwitch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving through
a tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.> Switching on: Press switch

The indicator lamp on the switch comes on.
>Switching off: Press switch4 once more.
The indicator lamp on the switch goes out.
DefrostingThe best defrosting of windows is achieved if
the ice is completely removed from the win

dows manually with an ice scraper before
starting the engine.

Warning!
When the recirculation mode is switched
on, windows can fog on the inside immedi

ately. Fogged windows impair visibility,
endangering you and others. If the win

dows begin to fog on the inside, switching
off the air recirculation mode immediate

ly should clear interior window fogging. If
interior window fogging persists, make
sure the air conditioning is switched on,
turn the air distribution control to
positionP (

page 150) and increase
air volume
1.
G
Warning!
Never drive with iced up or fogged
windows. Visibility will be significantly
impaired. Impaired visibility could en

danger yourself and others. This may
prevent you from observing the traffic
conditions, thereby causing an accident

Tires and wheels
>> Operation
203
Quality grades can be found, where applica

ble, on the tire sidewall between tread shoul

der and maximum section width. For example:
All passenger car tires must conform to fed

eral safety requirements in addition to these
grades.
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 may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.Traction
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
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.
Temperature
The 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 corre

sponds 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 represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.

Warning!
The traction grade assigned to this tire is
based on straight
ahead braking trac

tion tests, and does not include acceler

ation, cornering, hydroplaning, or peak
traction characteristics.
G
Warning!
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load

ing, either separately or in combination,
can cause excessive heat build
up and
possible tire failure.
