Jump Starting - Volvo C70 Owner's Manual

Jump starting

Starting with a donor battery
If the battery in the car has become flat, you
can "borrow" electric current from either a
separate battery or the battery in another car.
Always make sure the crocodile clips on the
jump leads are attached securely to eliminate
sparks during the start attempt.
When jump starting the car, the following
steps are recommended to avoid risk of
explosion:
– Turn the ignition key to position 0.
– Ensure that the donor battery is 12 V.
– If the donor battery is in another car,
switch off the engine in the other car and
ensure that the cars do not touch one
another.
– Connect the red jump lead between the
positive terminal on the donor
battery (1+) and the one in your car (2+).
– Connect one end of the black jump lead
to the donor battery's negative
terminal (3–).
– Connect the other end of the black jump
lead to the earthing point (4–) by the left-
hand strut tower.
– Start the engine of the "donor car". Let
the engine run a few minutes at a speed
slightly higher than idle (1500 rpm).
– Start the engine of the car with the flat
battery.
– Remove the jump leads, first the black
and then the red. Ensure that neither end
of the black jump lead comes into contact
with the battery's positive terminal or the
crocodile clip on the red jump lead.
Do not touch the crocodile clips during the
start procedure. This could cause sparking.
Starting and driving
WARNING!
The battery can generate oxyhydrogen
gas, which is highly explosive. One spark,
which can be generated if you connect the
jump leads incorrectly, is sufficient to
make the battery explode.
The battery contains sulphuric acid, which
can cause serious burns. If the acid
comes into contact with eyes, skin or
clothing, flush with large quantities of
water. If acid splashes into the eyes, seek
medical attention immediately.
