Temperature adjustment
You can turn to select the
desired temperatures for the
driver's and passenger sides.
Your settings appear on the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains this
temperature, regardless of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
Adjusting air supply manually
You can adjust the air supply by
turning. The automatic air sup-
ply control is operational when-
ever you see your selection rep-
resented by a bar on the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic air
supply mode with the AUTO button.
Switching air conditioner mode on
and off manually
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The temperature display reverts
to 607/166 while the system
switches to the recirculated-air mode and

son you should ensure that these outlets
are open before selecting this program.
Outside air/AUC Automatic
recirculated-air control/recirculated
air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
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
into the vehicle
>Left 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, in the auto-
matic mode the system may start to
alternate between its outside-air and
recirculated-air modes
>Right indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is permanently blocked. The
system then recirculates the air cur-
rently 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 air
supply as required.<
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's settings when the ignition lock is in

4.Extend the ski bag between the front
seats. The zipper allows more conve-
nient access to stored objects and can
also be left open to allow the ski bag to
dry.
Please ensure that the skis are clean before
loading them into the bag. Take care to
avoid damage from sharp edges.
Securing load
After loading, secure the ski bag and its
contents. Tension the retaining strap on the
tensioning buckle for this purpose.
Secure the ski bag in this way. If you
fail to do so, it could endanger occu-
pants during braking or evasive maneu-
vers.<
Stowing ski bag
1.To close the hatch in the luggage com-
partment:
Press the handle and slide to the left
2.Fold up the ski bag and place it in the
compartment 3.Engage the cover as shown
4.Close the cover.

Things to remember when driving
124 ensured that the radiation which results
during transmission will be discharged
from the vehicle interior.<
Cargo loading
To avoid loading the tires beyond
their approved carrying capacity,
never overload the vehicle. Overloading
can lead to overheating and increases the
rate at which damage develops inside the
tires. The ultimate result can assume the
form of a sudden air loss.<
Determine loading limit
1.Locate the following statement on your
vehicle's door pillar
*:
The combined weight of occu-
pants and cargo should never
exceed XXX lbs. or YYY kg, as other-
wise the vehicle may be damaged and
unstable driving conditions may
result.<
2.Determine the combined weight of the
driver and passenger that will be riding
in your vehicle
3.Subtract the combined weight of the
driver and passenger from XXX lbs. or
YYY kg
4.The resulting figure equals the available
amount of cargo and luggage load
capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be five 150-lbs.
passengers in your vehicle, the amount
of available cargo and luggage load
capacity is 650 lbs.:
1,400 Ibs. minus 750 Ibs. = 650 Ibs.5.Determine the combined weight of lug-
gage and cargo being loaded on the
vehicle. That weight should not exceed
the available cargo and luggage load
capacity calculated in step 4
6.If your vehicle will be towing a trailer,
part of the load from your trailer will be
transferred to your vehicle. Consult the
manual for transporting a trailer to
determine how this may reduce the
available cargo and luggage load
capacity of your vehicle.
Load
The permitted load is the total of the weight
of occupants and cargo/luggage. The
greater the weight of occupants, the less
cargo/luggage can be transported.
Stowing cargo
>Load heavy cargo as far forward and as
low as possible, placing it directly
behind the bulkhead behind the rear
seats
>Cover sharp edges and corners
>For very heavy cargo when the rear seat
is not occupied, secure each safety belt
in the opposite buckle.
