The red engine oil pressure warning symbol
requires immediate service or repair.

flashes, the oil pressure is too low. In add ition
to the symbol, the following message also ap­
pears in the display:
Switch off engine! Oil pressure is too low
.,. Pull off the road and stop the vehicle.
• Shut the eng ine down.

(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.

164 Fuel suppl y and filli ng your fuel t ank
fuel container in your vehicle . The con­
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 po rtable fuel conta iner
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the tr unk). Static electrici­
ty can bui ld up while filling and can ig­
n ite fuel vapors causing a fire .
- Always place a po rtable fuel container
on the ground before filling.
- Always keep the f iller nozzle complete­
l y inside the portable container before
and d uring fi lling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
he lp prevent static electricity from dis­
charging and cause a fi re .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fuel vapors are
h ighly flammable.
- Always observe local and state/provi n­
cial laws regarding the use, storage
and transporta tion of fuel conta iners.
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F8S2 -86) .
d) Note
If any fuel has spilled onto the car, it
should be removed immediate ly to prevent
damage to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
switches off automatically for the first
time, the tank is full. Do not try to add more fue l because fuel may spill out. In
add it ion, the expans ion space in the fuel
tank will be fi lled -causing the fue l to
overflow whe n it becomes warm and pol­
lute the env ironment.
(D Tips
- Running your engine whi le refue lling
may cause vapors to escape or even fuel
to spill out of the tank. This would then
shut off the fuel nozz le before the tank
is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may otherwise not ind icate the correct fue l
level after ref uelling .

necessary -
first plus, then m inus.
When charging at
low voltages (e.g. with a
trickle charg er), the battery cables do not
h ave to be d isconnected first. Before charging
at
high voltages, i.e. " fas t charging ", you
must disconnect both cables. In e ithe r case,

It r e­
q ui res specia l charg ing equipment and the
know ledge to go with it. We recommend hav­
ing your battery fast charged on ly by a quali­
f ied workshop .
A discharged battery can
freeze at tempera ­
tures of on ly 32 °F (0 °C). A llow a frozen bat­
tery to thaw completely befo re attempting to
charge it¢ & . However, we recommend not
using a thawed battery again because the bat­
tery cas ing can be cracked due to ice forma­
tion and can leak battery acid.
Do not open the battery caps when charging
the battery.
A WARNING
-
Charging a battery can be dangerous.
Checkin g and fillin g 179
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries wh ich were fro­
zen. 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 elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive.
- To reduce the danger of explosion, never
connect or d isconnect c harger cab les
while the charger is ope rat ing.
- Fast cha rging a batte ry is dangerous and
should only be attempted by a compe­
tent techn ic ian with the prope r equip­
men t.
- Battery acid that may spi ll dur ing cha rg­
i n g should be washed off wi th a solu tion
of wa rm w ater and baking soda to neu­
trali ze the ac id.
