Porsche 968 - Bulb Chart; Vehicle Bulb Locations and Types

Jump Lead Starting
If the engine will not start , e.g. because the bat-
tery is flat in winter, or after your Porsche has
been left standing for a prolonged period of
time, the battery of another vehicle can be used
as an auxiliary. For this you will need jump
leads. When starting your Porsche in this way
keep the following in mind:
1. Both batteries must be 12-volt batteries. The
capacity (Ah) of the feed battery must not be
too much lower than that of the flat battery .
2. Only jump leads of sufficient cross-section
and fitted with insulated terminal clamps may
be used. Always follow the manufacturer's in-
structions.
3. A flat battery can freeze at - 10 °C. A
frozen battery must be thawed out before
jump cables are connected to it.
4. There should be no contact between the ve-
hicles . Otherwise, current may flow as soon
as the positive terminals are connected .
Danger of short-circuit!
5. The flat battery must be correctly connected
to its vehicle's electrical system. Do not
stoop over the battery.
Danger of contact with caustic fluid!

6. Protect the battery from sources of fire
such as naked flames, burning cigarettes,
sparks caused by electrical wiring or weld-
ing etc.
Danger of explosion!
Be careful not to allow conductive jewelry
such as rings, necklaces, watchstraps etc.
to come into contact with live parts of the
due to short-cir -
7.
Connect the jump leads in such a way that
they cannot be caught up by rotating parts in
the engine compartment.
Conne ct the jump leads as follows:
First connect the + lead to the + terminal of
the flat battery (A), then to the + terminal of
the feed battery (B) , then
connect the - lead first to the - terminal of
the feed battery,
then connect the other end to a suitable ear -
thing point (4) on the engine or on the body
of the car with the flat battery. This earthing
point must be as far as possible from the
battery .
8. Start the engine of the vehicle with the sup-
plying current. Run engine with higher rpm. ·
9.
Start the engine . Do not crank the engine for
more than 15 seconds; wait for at least 1
minute before repeating the attempt.
10. With the engine running, disconnect the ca-
bles in the reverse order.
