c::> page 75, fig. 77.
The 12 volt sockets can be used for electr ica l
accessories . Th e power input must not exceed
120 watts . Before you purchase any accessories
, always
read and follow the information in
c::, page 294, Additional accessories and parts
replacemen t.
A WARNING
The sockets and the electrical accessories
connected to them operate only when the
i gnition is switched on . Incorrect usage
ca n lead to ser ious injuries or burns. To re­
duce the risk of inj uries, never leave ch il­
dren unattended in t he vehicle with the ve­
hicle key .
(D Note
To avoid damaging the socket, only use
plugs that fit p roperly.
- Never connect equ ipment that generates
elect rical current, such as a solar panel
or battery charger, to the 12 vol t socket .
T his could damage the vehicle 's elect ri­
cal sys tem .
- The 12 volt socket shou ld only be used
for a short per iod of t i me as a power
so urce for electrical equ ipment . Please
use the electrical sockets in the vehicle
when connecting equipment for longer periods.
@ Tips
When the engine is off and accessories are
still plugged in and are on, the vehicle bat­
tery can still be drained.

- 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!
