charged with a charger or the vehicle may be
jump started with assistance from another ve
hicle in the same way as a conventional vehi
cle .
The same applies to the high voltage battery
if it is d ischarged . However, in this case, the
charg ing process is accompanied w ith mes
sages in the inst rument cluste r display. The
i gnit ion m ust be switched on and all unneces
sary electric components m ust be turned off.
The connections in the engine compartment
are used for both charging and jump starting
c::> page 245 or c::> page 284.
Vehicle not ready to start. See owner's
manual
This message appears if the high voltage bat
tery charge level is too low. The vehicle can no
l onge r be started with its own power. The
high voltage battery must be charged with a
charger or the vehicle must be jump started
with the aid of another vehicle.
Afte r the connecting the cha rger or jumper ca
b les, the ignition must be turned off for ap
proximately two minutes and then turned on
again. After no more than one m inute, one of
the following indicator lights turns on in the instrument cluster d isp lay. Hybrid 105
II Charging battery. Please wait ...
If
the indicator light turns on and this mes
sage appears, the high voltage battery is
charging or the vehicle is being jump started
with assistance from another vehicle.
If the 12 vo lt batteries are dead, the -
indicator light turns on. The charging proce
dure takes longer in this case because the
12
volt batteries are charged first. The procedure
goes faster with the ignition switched off.
Vehicle ready to start.
This message appears if the charging proce
dure was successfu l. The vehicle may be start
ed again.
Battery could not be charged enough to
start vehicle.
T his message appears if the charging proce
dure was not successful or it was interrupted.
This may happen if the charger or the battery
in the veh icle that is assist ing is too weak.
If
the vehicle cannot be started, see an author
ized repa ir facility for assistance .
(D Tips
- The charger should deliver a current of at
least
30 A. Otherwise charging the high
voltage battery will take considerably longer. A current between
50 A and 70 A
is ideal.
- The ve hicle that is assist ing should be
somewhat within the same vehicle class
when jump starting a vehicle. A smaller
vehicle's battery may be drained.
- After approximately
30 minutes, the
c harging procedure ends because the ig
nition is automatically turned off.
If you
would like to continue to charge the bat
tery, turn the ignition on again.
232 Fuel supply and filling your fuel tank
-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. Th is 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
F 852-86).
(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 sw itches 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 fue l to
overflow when it becomes warm and pol
lute the environment.
@ Tips
- Running yo ur engine while refuelling
may cause vapors to escape or even
cause fue l 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 turned on. The fuel gauge may oth
erwise 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. Unlocking the fuel filler flap
by hand
You can open the fuel filler flap by hand if the
power locking system should fail.

c;, fig. 193. Now you can open the fuel
filler flap as usual.
-Do not interchange the positive and neg
ative cables .
- When working on the battery , be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen 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 ca
ble .
- Before performing any work on the elec
trical system , switch off the engine and
ignition as well as any electrical equip
ment. The negative cable on the battery
must be disconnected. If you are just go
ing 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! Other
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch
ed off. Reconnect the positive cable first
and then the negative cable. Never inter
change the cables - this could start a fire!
- Never charge a fro zen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dis
charged battery can freeze over at 32°F
(OOC) .
-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.
