Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail , you can
still open the flap manually - for detailed instruc­
tions see
~ page 195 .
You can find the fuel tank capacity of your vehicle in
~ page 262 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For mo re in­
formation about fuel specifications , see
~ page 191 .
You r vehicle fuel tank has an onboa rd refuelling
vapor recovery sys tem . This fea tu re helps to pre­
vent fuel vapors from escaping from the tank and polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please follow this
refueling procedure carefully.
_& WARNING
Under norma l operating conditions, never car­
ry additiona l fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous. Such containers,
full or empty, may leak and could cause a fire
in a collision . If you must transport fuel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fue l can cause misfiring. Gasoline could enter
the exhaust system and damage the catalyt ic
converter.

neck until it cannot turn any farther.
"' Then press on the left s ide of the tank door un-
til it latches.
Once the pump nozzle switches off, the fuel tank
is "full ". Do not fill the tank mo re . Otherwise the
expans ion space in the tank w ill be filled .
The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. Fo r additional informa tion on fuel,
see
~ page 191.

Checking and Filling
The fuel tank capacity of your vehicle is listed in
the
Technical Data section ~ page 262.
To avoid fuel spilling or evaporating from the fuel
tank always close fuel cap properly and com­
pletely. An improperly closed fuel filler cap may
also cause the MIL lamp~
page 25 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries .
- Fuel ignites easily and can cause serious burns and other injuries .
- If you do not switch the engine off when fu­
eling and/or do not insert the fuel no zzle
completely into the tank opening, fuel can
leak out or run over . Leaked fuel can ignite
and start a fire .
- Do not use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling . If
you must make an exception and enter your
vehicle again while fueling, close the door
and touch metal to discharge static electric­ity before touching the fuel nozzle . Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:
- Never fill the fuel container with fuel
while it is in or on the vehicle. Static elec­
tricity is discharged when filling which can
cause the fuel vapors to ignite and in­
creases the risk of an explosion.
- Always place a fuel container on the
ground before filling.
- Always hold the fuel nozzle completely in
the fuel container when filling.
194
-If the fuel container is made of metal, the
fuel nozzle must always be in contact with
the container when filling it with fuel. This
prevents static electricity from discharg­
ing .
-Never spill fuel in the vehicle or the lug­
gage compartment . Evaporated fuel is ex ­
plosive and increases the risk of serious in­
jury or death .
- Follow legal requirements when using, storing and transporting fuel containers .
- Make sure the fuel container conforms to industry standards (ANSI/ASTM F852-86).
(D Note
-Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re­
sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter .
(D Note
Applies to: vehicles with diesel eng ines
If the fuel tank runs completely empty, the
ignition must remain switched on for at least
30 seconds after refueling before starting the
engine. It may take longer than usual for the
engine to start, even up to a minute. This is
because the air must first bleed out of the
fuel system when starting the engine.
@ For the sake of the environment
Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming up.
(y Tips
The fuel filler door on your vehicle does not lock if you lock the vehicle from the inside.

Catalytic converter
Applies to: vehicles with gasoline engine
It is very important that your emission control
system (catalytic converter) is func tioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline c> page 191, Fuel
supply .
~ Never run the tank down all the way to empty.
~ Never put too much motor o il in your engine
c> page 204, Adding engine oil.
~ Never try to push- o r tow-start your vehicle .
The catalytic converter is an efficient "clean -up "
device built into the exhaust system of the veh i­
cle. The catalyt ic converter b urns many of the
po llutants in the exhaust g as befo re they are re­
l eased into the atmosphere.
The exclusive use of un leaded fuel is critically im­
po rtant fo r the life of the catalytic converte r and
prope r funct io ni ng of the engine.
_&. WARNING
The temperat ure of the exhaus t sys tem is
high, both when driv ing and a fter stopping
the engine.
-
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- D o not p ark or operate the vehicle in ar eas
where the hot exhaust system may come in
contact with dry g rass, brush, fuel spi ll or
other mate rial which can ca use a fire.
- Do not apply additiona l undercoating or
rustp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic conve rter or
heat shields . D uring driving, the substance
used for unde rcoat ing could overheat and
cause a fire .
Cl) Note
-Be aware that just one tank f illing wit h
leaded fu e l w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
