92 rarily suspending the supply of outside air.
The system then recirculates the air cur-
rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows in
>Right indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required. The sys-
tem then recirculates the air currently
within the vehicle.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air
and recirculated-air modes
>Left indicator lamp on, recirculated-air
mode: the supply of outside air is per-
manently blocked. The system then
recirculates the air currently within the
vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing
the air volume as required.
The recirculated-air mode should not be
used over a sustained longer period of
time, as the air quality inside the vehicle
deteriorates continuously.<
Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle is
stopped at a school to pick up a
child.
You can adjust the automatic climate con-
trol settings in ignition key position 1.
Provided that the engine has warmed
to its normal operating temperature
and the battery is charged, you can use this
function for up to 15 minutes after switch-
ing off the ignition. The LED within the but-
ton lights up to confirm compliance with
these conditions.<
Switching automatic climate control
off
The air volume, the heater and
the cooling function are all
switched off. You can restart
the automatic climate control
by pressing any of its buttons
except the REST button.

Front ventilation
You can adjust the vent outlets for the
upper body to suit your personal require-
ments.
You can use the serrated dials 1 to open
and close the vent outlets through an infi-
nitely-variable range, while the levers 2
allow you to adjust the airflow direction.
Ventilation for cooling
Adjust the vent outlets to direct the flow of
cool air in your direction, for instance, if the
interior has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you.
You can also individually adjust the air tem-
perature of the vent outlets for the upper
body area using the Control Center.
Rear ventilation
The serrated dial 1 allows you to open and
close the vents through an infinitely-vari-
able range.
Serrated dial 2:
Turn towards blue: colder.
Turn towards red: warmer. You can adjust the airflow direction using
the levers 3.
Independent ventilation*
The independent ventilation blows air into
the passenger compartment to lower inte-
rior temperatures.
System operation is controlled using the
Control Center. You can set two different
times for the system to start.
The system remains on for 30 minutes. It
can also be switched on and off directly.
Since the system uses a substantial
amount of electrical current, you should
refrain from activating it twice in succes-
sion without allowing the battery to be
recharged in normal operation between
use.
The independent ventilation system is
available for preprogrammed operation at
outside temperatures above approx. 597/
156 and for direct activation at any tem-
perature, but is not operational when the
vehicle is underway.
The air enters the passenger compartment
through the vent outlets in the instrument
cluster, which can be adjusted for both
direction and airflow. These vent outlets
must be open for the system to operate.
Switching on and off directly
1.Turn the ignition key to position 1
Control Center, for principle details, refer to
page 16:
2.Open "Climate"
3.Select "Independent ventilation" and

Glove compartment
Opening
Pull the handle. The light in the glove com-
partment switches on.
Closing
Fold the cover up.
To prevent injury in the event of an
accident, close the glove box immedi-
ately after use.<
Locking
Lock with a central key. Unlocking is also
only possible with a central key.
If you only hand over the spare key,
e.g. in a hotel for valet parking, refer
to page 26, the glove compartment cannot
be opened.<
Rechargeable flashlight
The flashlight is located on the left side of
the glove compartment.
It features integral overload protection, so
it can be left in its holder continuously.
Be sure that the flashlight is switched
off when it is inserted into its holder.
Failure to comply with this precaution
could lead to overcharging and damage.<

A storage compartment is located in the
armrest between the front seats.
To open the cover:
Press the button. The cover opens and can
be folded upwards.
The mat within the compartment can be
removed for cleaning.
Depending on the version, the storage
compartment can contain a folding tray or a
telephone cradle

dently of the fact that tires can reach an age
of 10 years.
Uniform Tire Quality Grading
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.<
Treadwear
The treadwear grade is a comparative rat-
ing 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 g) 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 govern-
ment test surfaces of asphalt and concrete.
A tire marked C may have poor traction
performance.
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics.<
Temperature
The temperature grades are A Ð the
highest Ð 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 level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A repre-
sent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
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 heat buildup and possible tire
failure.<
RSC Ð Run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the
side of the tire, refer to page 175.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
Tire condition
Inspect your tires frequently for treadwear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
Tire tread
The tread depth should not drop below
0.12 in/3 mm, although, for example, Euro-
pean legislation only specifies a minimum
tread depth of 0.063 in/1.6 mm. At tread
depths below 0.12 in/3 mm there is an
increased risk of high-speed hydroplaning,
