A WARNING
Improper refueling or handling of fue l can
cause fire, exp losion and severe burns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off whi le refuel­
ing and/or to insert the pump nozzle fu lly
into the fuel filler neck could cause fue l to
spray out of f iller neck or to overflow. Fuel
spray and overflow ing fuel can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling. If in exceptional c ircumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discharge static e lectric­
ity before touching the filler nozzle again.
Fu el and R efu elin g
Static electricity can cause sparks that can
ignite fuel vapors released during refue ling.
- Never smoke or have an open f lame any­
where in or near your vehicle when refueling or filling a portable fuel conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable f uel
container in your veh icle. The container, full
or empty may leak and cou ld cause a fire,
especially in a crash .
- If, under exceptional c ircumstances, you
must transport a portab le fuel container,
please observe the following:
- Never fill a portable fuel container while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compartment, or on
the trunk). Static e lectric ity can build up
while filling and can ignite fuel vapors
caus ing a fire .
-Always place a portab le fue l conta iner on
the ground before fill ing .
- Always keep the filler nozzle completely
inside the portable container before and
during f il li ng.
- If filling a portab le container made of
metal, the f iller nozzle must always be in
contact with the container. This will help prevent static electricity from d ischarging
and cause a fi re.
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable.
- Always observe local and state/provincial
laws regarding the use, storage and trans­
po rtation of fue l conta iners.
- Make certain the fuel conta iner meets in­
dustry standards (ANSI/ AS TM F852 -86).
(D Note
If any fuel has sp illed onto the car, it should
be removed immediately to prevent damage
to the pa int.
@) For the sake of the environment
As soon as the correct ly operated nozzle
switches off automat ically for the first time,

Checking and Filling
-If you get battery acid in your eyes or on
your skin, immediately rinse with cold wa­
ter for several minutes and get medical at­
tention .
- If you should ingest any battery acid, seek
medical attention immediately .
- Do not expose the battery to an open flame, electric sparks or an open light .
- Do not smoke .
- Do not interchange the positive and nega-
tive cables.
- When working on the battery , be sure not to
short-circuit the terminals with tools or oth­
er metal objects . This would cause the bat­
tery to heat up very quickly, which could lead to damage or explosion and personal
injury .
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children .
- 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 anti-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 .
202
-Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.
A WARNING
California Proposition 65 Warning:

(D Note
- Do not disconnect the vehicle battery when
the ignition is switched on or when the en­
gine is running, otherwise, you will damage
electronic components in the electrical sys­
tem .
-If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing", otherwise it
will be damaged and will then have to be re­
placed .
