Fuel and Refueling
-Always keep the fi ller nozzle completely
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 discharging
and cause a fire .
-Never sp ill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammab le.
-Always observe local and state/provincia l
laws regarding the use, storage and trans­
portat ion of fuel containers.
- Make certain the fuel container meets in­
dustry 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 addition, the
expansion space in the fuel tank will be filled·
causing the fuel to overflow when it becomes
warm and pollute the environment.
(j) Tips
- Running your engine while refuelling may
cause vapors to escape or even cause fuel to
sp il l out of the tank . This wo uld then shut
off the fuel nozzle before the tank is full.
- Do not refuel your veh icle with the ignition
turned on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- The fuel filler flap of your vehicle is not
l ocked when you lock the vehicle from the
inside .
186
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail .

Checking and Filling
-Before work is done on the electrical sys­
tem, disconnect the negative ground cable .
- Before performing any work on the electri­
cal system, switch off the engine and igni­
tion as well as any electrical equipment. The
negative cable on the battery must be dis­
connected . If you are just going to replace a
light bulb, then it is enough to switch off
the lights.
- Before disconnecting the battery, switch off
the ant i-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis­
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off. Re­
connect the positive cable first and then the
negative cable. Never interchange the ca­
bles -this could start a fire!
- Never charge a frozen or a thawed-out bat­
tery. It could explode! If a battery has fro­
zen, then it must be replaced. A discharged
battery can freeze over at 32°F (0°C) .
- Make sure the vent hose is always attached
to the opening on the side of the battery.
- Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.
