Starting with a booster battery
If for some reason the battery in your car is
discharged, you can " borrow " current from
a spare battery or another car’s battery to
start the engine. Always check that the
clamps are fastened properly to prevent
sparking during the start attempt.
To avoid the risk of explosion, we recommend
you do exactly as follows.
– Turn the ignition key to position
0 .
– Ensure that the other battery is 12 volt.
– If the booster battery is in another car,
stop the engine of that car and make sure
the cars are not touching.
– Connect the red cable between the
booster battery positive terminal (1+) and
the red connection in the engine
compartment (2+).
Attach the clamp to the contact point
located beneath a small black cover with
a plus sign which is integrated in the fuse
box cover.
– Connect one clamp of the black cable to
the negative terminal of the booster
battery (3–).
– Connect the other clamp of the black
cable to the lifting eye on your car’s
engine (4–).
– 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 clamps in reverse order.
NOTE!
Do not remove the clamps during the
start attempt (risk of spark build-up).
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.
