temperat ure falls below 131 °F (55 °C) again,
the cooler switches on again automatically.
- the battery is adequately charged . The cooler
switches off automatically if the vehicle battery
voltage falls below a minimum level. This pre­
vents the battery from discharging. The cooler
switches back on again automatically when the
battery voltage increases again (e.g. after start ­
ing the engine) .
The cooler cools to 42.8 °F
(+ 6 °C) and the freez­
er cools to 21.2 °F (- 6 °C) in optimum cooling
conditions . The cooling performance is affected
by the temperature in the luggage compartment .
The temperature inside the cooler will be higher
if the luggage compartment is hot .

A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns .
- Fuel is highly f lammable and can cause se­
vere burns and other injur ies.
-
- Failure to shut the engine off wh ile refuel ­
ing and/or to insert the pump no zzle fully
into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow . Fuel
spray and overflowing fue l can cause a fire .
- Never use a cellular telephone wh ile refuel­
ing . The electromagnetic radiation can
cause spa rks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling .
If in except io na l circumstances you
must get back in you r vehicle while refue l­
ing, make certain tha t you close the door
and touch meta l to discharge static electric­
ity before touchi ng the filler nozz le again.
Static electricity can ca use spa rks that can
ignite fuel vapors released during refueling .
- Never smoke o r have an open flame any­
where in or near your vehicle when refueling or filling a portable f uel container.
- For yo ur safety , we strongly recommend
that you do not travel with a portable fue l
conta iner in your vehicle. The conta iner, full
or empty may leak and could cause a fire,
especially in a crash .
-If, under exceptional c ircumstances, you
must transport a portable fuel container,
please observe the follow ing :
- Neve r fi ll a portable fuel containe r wh ile i t
is anywhere in or on the vehicle (for exam ­
p le, in the luggage compartment, or on
the trunk) . Static e lectr icity can build up
Fuel and R efueling
whi le filling and can ignite fuel vapors
caus ing a fire .
- Always place a portab le fue l container on
the ground before f illing.
- Always keep the fi ller nozzle comp lete ly
inside the po rtable container before and
during f illing.
- If filling a portable container made of
metal, the filler nozz le m ust always be in
contact with the container. This will he lp
prevent stat ic electricity from discharging
and cause a fire .
- Never spill fue l inside the vehicle or lug­
gage compartment. F uel vapors are highly
flammable .
- Always observe local and state/prov incial
laws regarding the use, storage and trans ­
po rtation of fuel co nta iners.
- Make ce rtain t he f uel container meets in­
dust ry standards (ANSI/ ASTM F852-86) .
(0 Note
If any fuel has sp illed onto the car, it should
be removed immed iately to p revent damage
to the pa int.
@ For the sake of the environment
As soon as the correctly operated noz zle
switches off automatically for the first time,
the tank is fu ll. Do not try to add more fuel
because f uel may sp ill out . In add it ion, the
expans ion space in the fuel tank will be fi lled -
causing the fue l to overflow when it becomes
warm and po llute the environment.
(D Tips
- Runn ing your engine while refuelling may
cause vapors to escape or even ca use fue l to
spill out of the tank. This wo uld then shut
off the f uel no zzle befo re t he t ank is f ull.
- Do not ref ue l your veh icle with the ignition
switched on . The fuel gauge m ay o therwise
no t indicate the co rrect fuel leve l after refu­
elling.

Checking and Filling
A discharged battery can freeze at temperatures
of only 32 F
0 (0 °C). Allow a frozen battery to
thaw completely before attempting to charge it
¢ &. However , we recommend not using a
thawed battery again because the battery casing can be cracked due to ice formation and can leak
battery acid.
Battery charging (Maximum charging rate of
30 amps/14.8 Volt)
When charging at low voltages (e.g . w ith a trick­
le charger),
the battery cables do not have to be
disconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the battery from
the luggage compartment, and it is also not nec­
essary to disconnect the cables .
Fast charging the battery (charging rate
above 14.8 Volts)
For technical reasons do not use a battery charg­
er that uses voltage greater than 14.8 Volts to
charge your vehicle's battery.
.&_ WARNING
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manufactur­
e r when charging your battery.
- Never charge a frozen battery. It may ex­
p lode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen.
The battery housing may have cracked and
weakened when the battery froze.
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark. Do not smoke. Hydrogen gas generat­
ed by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a competent
technician with the proper equipment.
