Jumpstarting
Jumpstarting with a booster battery is as
follows:
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 secure so that there are no sparks 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 booster battery has 12 volt current.
· 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 to the booster battery's positive terminal (1+)
and the red connection in your car's engine by (2+).
The clamp should be attached to the contact point located under a little
black cover with a plus sign on it. The cover is connected to the cover
of the fuse box.

· Connect one end of the black cable to the booster battery's negative
terminal (3).
· Connect the other end of the black cable to the lifting eyes on you car.

· Start the engine of the "booster 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 discharged battery.
· NOTE! Do not move the clamps during the start attempt (risk of
spark buildup).
· Remove the clamps in reverse order.
WARNING!
Batteries 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.
