-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
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 portable fuel container
on the ground before filling .
- Always keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler 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 local 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 spilled onto the car, it
should be removed immediately 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 fuel because fuel may spill out. In
Checking and Filling 209
addition, the expansion space in the fuel
tank will be filled -causing the fuel to
overflow when it becomes warm and pol­
lute the environment.
@ Tips
-Running your engine while refuelling
may cause vapors to escape or even
cause fuel to spill out of the tank. This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refuelling .
- The fuel filler flap of your vehicle is not
locked when you lock the vehicle from
the inside.

If the central locking system is faulty, the
fuel filler door can be unlocked manually .

and then the negative cable . Never inter­
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dead battery can freeze over at 32°F (0°C).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery.
&_ WARNING
California Propos ition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
t ive p roblems. Wash hands after han­
dling.
(D Note
- Do not d isconnect t he veh icle battery
when the ignition is on or when the en­
gine is running, otherwise, you will dam­
age ele ctron ic componen ts in the elec tri ­
ca l system.
- If your vehicle is going to stand for a

A d ischarged bat tery can freeze at tempera ­
tu res of only 32 F
0 (0 °C). Allow a frozen bat­
tery to thaw completely before attempting to charge it
r=;, .&, . However, we recommend not
using a thawed battery again because the bat­
te ry casing can be cracked due to ice forma-
t ion and can leak battery acid . ..,.

Battery charging (Ma ximum charging rate
o f 30 am ps/ 14.8 volt s)
When charging at
low voltages (e.g . with a
tri ckle ch arg er), the batte ry cables do not
have to be d isconnected 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
necessary to disconnect the cables.
F ast charging th e battery (charging rate
a bo ve 14 .8 volt s)
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
volts to charge your ve hicle 's battery .
A WARNING
Charging a battery can be dangerous .
- Always follow the operating instructions
provided by the battery charge r manu­
fact urer when charging your battery .
- Never charge a frozen battery . It may ex ­
plode because of gas t rapped in the ice .
Allow a frozen battery to thaw out first.
- Do not reuse batteries which we re fro ­
zen . The batte ry housing may have
cr acked and weakened whe n the battery
froze.
- Charge the battery in a we ll ventilated
area. Keep away from open flame o r ele c­
trical spark. Do not smoke. Hydroge n gas
generated by the battery is exp losive.
- T o redu ce the danger o f explosion , never
conne ct or disconnect cha rger cables
wh ile the charger is operating .
- F ast charg ing a battery i s dangerous and
sho uld on ly be attempted by a compe­
tent technician with the proper eq uip ­
me nt.
- Battery acid that may spill during charg ­
ing should be washed off with a so lution
of warm water and ba king soda to neu­
tralize the acid.

@ Note
Neve r use a fast charger as a booster to
start the eng ine . This w ill seriously dam­
age sens itive e lectronic components, such
as contro l units, relays, radio, etc., as well
as the batte ry charger .
Battery replacement
The new ba ttery mus t hove the some specifi­
cations and dimensions as the original equip­
ment battery .
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
ca l ene rgy throughout your vehicle
~ page 190 . The intelligent energy manage­
ment system will keep the engine battery
c h arged better than vehicles without this sys­
tem. To make sure the addition al ele ctri cal e n­
ergy is ava ilab le once again after yo u have
changed the batte ry, we recommend that you
insta ll batteries of the same type an d manu­
facture on ly (the same as those insta lled at
the time your veh icle was delivered) . Specif i­
cations are listed on the battery housing. Your
authorized dea ler must code the battery in
the ene rgy management system to enab le you
to use the ene rgy management functions cor­
re ct ly afte r repla cing the battery.
The new battery must have the same capacity,
vo ltage ( 12-volts) , amperage, construction
and plug sea ling .
When install ing the battery, make sure the ig­
nition and a ll electrical consumers are switch ­
ed off .
~ Note
Make sure the ventilat ion hose on the side
of the battery is con nected, otherwise
fumes o r batte ry acid can lea k out.
