- the temperature in the luggage compart­
ment is below 131 °f (55 °C). The cooler
switches off automatically if the tempera­
ture in the luggage compartment exceeds 131 °f (55 °C) . Once the temperature falls
below 131 °f (55 °C) again, the cooler
switches on aga in automat ically .
- t he battery is adequately charged . The cool­
er switches off automatically if the vehicle
battery voltage falls below a minimum lev­
el. This prevents the batte ry from discha rg­
i ng . The cooler switches back on again auto­
matically when the battery voltage increases
again (e.g . after starting the engine).
The cooler cools to 42.8 °f
(+ 6 °C) and the
freezer cools to 21.2 °f (- 6 °C) in opt imum
cooling cond itions . Th e cooling performance
is affected by the temperature in the luggage
compartment. The temperature inside the
cooler will be higher if the luggage compart­ ment is hot.
A WARNING
To avoid putting the occupants at any risk, please observe the following safety rules:
- The maximum capacity is 2.5 kg (5.5
lbs.).
- Never overload the cooler. This could cause injury in the event of a collision or
sudden braking.
- The coo ler lid must always be kept closed
while you are driving. Make sure the re­
taining catch is securely engaged . The
contents of the coo ler could be thrown
forward into the passenger compart­
ment in the event of a collision or under
sudden braking - risk of injury!
- Inflammable liquids, gas canisters, etc.
must not be stored in the cooler -risk of
exp losion! This also includes any prod­
ucts that might emit volatile or inflam­
mable gases.
- Liquids will freeze at temperatures at or
below 32 °f (0 °C) and may cause glass
bottles to burst!

Warm and cold Climate controls
Description
Th e climate control sy stem warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It is the most effect ive when the windows and
sunroof* a re closed. If the temperature inside
the parked vehicle becomes very warm, open­ ing the window briefly will speed up the cool­
ing process.
I n all heating mode f unctions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has r eached a certain
temperature.
Condensation from the cooling system can
drip and form a puddle of water under the ve­hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The po llutant filte r removes po llutants s uch
as dust and pollen from the air.
The air pollutants filte r must be changed at
t he intervals spec ified in you r Wa rra nty
