[ i ) Tip s
If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the
out lets completely .•
Using climate control economically
Using the climate controls prudently can help save fuel.
When you use the a ir conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditioner only when necessary . A lso please
note the follow ing po ints:
- If you want to save fuel, activate ECON.
- If yo u are g oing to dr ive wit h the w indows or Panorami c
sliding sunroof* open, use ECON .
- If the ve hicle is e xtremely ho t due to the heat of t he s un,
br iefly open doors and windows .
Contro ls and eq uip­
ment

ECON
The ECON mode helps to save fuel .
The air conditioning is turned off in ECON mode. "ECON" means
"Economy" . By switching off the air conditioning (compressor) , you
save fuel.
P lease note that vehic le interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or
dehum id ified.
If the vehic le interior becomes too hot or if the windows fog up,
ECON mode should be turned off . As soon as the [AUTO ] button in
the air conditioning controls is pressed , the system automatically
leaves the ECO N mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air q uality sensor detects increased concentrations of
pollu tants in the outside air and automatically switches
t o recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system
detects po lluted outside air, the sensor decides whether the air
po llution can be reduced by the factory -installed pollutant filter or
whether it is necessary to switch to air recirculation. With heavy ...

Warm and cold -
-------------------'
concentrations of pollutants, the air conditioning system is
switched automatically to recirculation mode and the supply of
outside air is blocked. As soon as the concentration of pollutants in
the outside air drops , fresh air is supplied to the vehicle interior
again.
In the event that the windows fog up during automatic air recircula­
tion, you must press the® button immediately.
Under certain operating conditions, automatic air recirculation is
switched off automatically . With outside temperatures below about
+10 °C, automatic air recirculation is limited to 30 seconds . With
outside temperatures below about -1 °C and in the ECON mode,
automatic air recirculation is limited to 15 seconds. •

Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C
Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width=>
page 359,
fig. 295.
For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require ­
ments in addition to these grades .
Tread wear
The tread wear 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 condi­
tions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differ­
ences 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 dissi­
pate 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 Band 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 traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels .
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle .
Your vehicle is equipped with all -wheel drive, this will improve trac­
tion during winter driving, even with the standard tires. However,
we strongly recommend that you always equip all four wheels on .,_
