A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe b urns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injur ies .
- Failure to shut the engine off wh ile refuel ­
ing and/or to insert the pump nozz le fully
into the fuel filler neck could ca use fue l to
spray out of filler neck or to ove rflow. Fuel
spray and overflowing fue l can cause a fire.
- Never use a cellular telephone wh ile refuel­
ing. The electromagnetic radiation can
cause spa rks that can ignite f uel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling. If in except ional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discha rge static ele ctric­
ity befo re touching the filler noz zle ag ain.
Fuel and R efueling
Stat ic elect ricity can cause sparks that can
ignite fue l vapors released during refueling.
- Never smo ke or have an open flame any ­
where in or near your vehicle when ref ueling
or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not trave l with a po rtable fuel
container in your veh icle. The container, fu ll
or empty may leak and co uld cause a fire,
especially in a crash.
- If, under except ional circumstances, you
m ust transport a portable fuel container,
p lease observe the following:
- Never fill a portab le fue l conta iner while it
is anywhere in or on the vehicle (for exam­
ple, in the l uggage compa rtment, o r on
the trunk). Static electricity can build up
while filling and can ignite fuel vapors caus ing a f ire .
-Always place a portab le fue l conta iner on
the ground before fi lling .
-A lways keep the f iller nozzle comp lete ly
inside the portable container before and
during f il li ng.
- If filling a portable conta iner made of
metal, the filler nozz le must always be in
contact with the container . This will he lp
prevent stat ic elec trici ty from discharging
and ca use a fire.
- Never spill fue l inside the vehicle o r lug­
gage compartment. F uel vapors a re highly
flammable.
- Always observe loca l and state/prov incial
laws rega rding the use, storage a nd trans­
po rtation of fuel contai ners.

Checking and Filling
-If you get batt ery 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 nega tive 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, sw itch 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.
Reconnect the positive cable first and then
the negative cable. Never interchange the
cabl es - 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.

(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.
