(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication
l!I requires oil refill or workshop serv­
ice without delay. Do not wait until the
red oil pressure warning. starts to
flash before you respond to the low oil
level warning
1!1-By then, your engine
may already have suffered serious dam­
age.

Refuelling procedure
"' Inse rt the fue l nozzle from the gasoline
pump into the fue l filler neck as far as it will
go.
"' Se lect a m edium refuelling rate so that the
noz zle switches off automatically when the
tank is full.
Putting the fuel cap back on
"' After filling your tank, twist the fuel cap
clockwise as far as it will go.
"' Close the fuel filler flap.
To avoid fuel spi lling or evaporating from the
fuel tank always close fuel cap properly and
comp letely.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu ­
eling and/or to insert the pump nozzle
fully into the fuel f iller neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflow ing fuel can
cause a fire.
- Never use a cellular telephone wh ile re­
fueling. The electromagnetic radiation
can cause sparks that can ign ite fue l va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling. If in exceptiona l circumstances
you must get back in your vehicle wh ile
refue ling, make certain that you close
the door and touch me tal to discharge
static electricity before touching the fill­
er nozzle again . Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel container.
- For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con-
Fuel supply and filling your fuel tank 213
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk) . Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire.
-Always place a portab le fue l container
on the ground before fi lling .
- Always keep the filler nozzle complete­
l y inside the portab le container befo re
and during filling.
- If filling a portable container made of
metal, the fi ller nozzle must always be
in contact with the container. This will
help prevent static electricity from dis­
charging and cause a fire .
- Never spill fuel inside the vehicle or
luggage compartment . Fuel vapors are
highly flammable .
-Always observe loca l and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers .
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852-86) .
(D Note
If any fuel has spi lled onto the car, it
should be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correct ly operated nozzle
switches off automat ically for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out . In
addition , the expansion space in the fuel
tank w ill be filled -causing the fuel to
overflow when it becomes warm and pol­
l ute the environment. •

tery to thaw completely befo re attempt ing to
charge it
c:> .& . However, we recommend not
usi ng a thawed battery again because the bat- tery casing can be cracked due to ice forma

t ion an d can leak battery acid.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt)
W hen charging at low vo ltages (e.g. wi th a
trickle charger ), the battery cables do not
have to be disconnected f irst . The battery
caps should
not be opened when charging a
battery.
It i s not necessa ry to remove the battery from
the luggage compartment.
Fast charging the battery (charging rate
abov e 14 .8 Volts)
F or technica l reasons do not use a battery
c h arger that uses voltage greater than 14.8
Volts to c harge yo ur vehicle's battery.
A WARNING
-----=--
Charging a battery can be dangero us.
- Always follow the operating instructions
provided by the battery cha rger manu­
factur er when charg ing your battery.
- Never charge a frozen battery. It may ex­
p lode because of gas trapped in the ice .
Allow a frozen batte ry to thaw out first.
