Introduction
This chapter contains information on the following subjects:
Jump-starting using the battery from another vehicle
Jump-starting in vehicles with the START-STOP system
The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat.
WARNING
Pay attention to the warning instructions relating to work in the engine
■
compartment » page 145.
A discharged vehicle battery may already freeze at temperatures just be-
■
low 0 °C. If the battery is frozen, do not jump start with the battery of an-
other vehicle – there is a risk of explosion.
Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
■
away from the battery – risk of explosion!
Never jump-start vehicle batteries with insufficient acid levels – risk of
■
explosion and chemical burns.
The vent screws of the battery cells must be tightened firmly.
■
Note
We recommend you buy jump-start cables from a car battery specialist.

If the engine does not start, halt the attempt to start the engine after 10 sec-
onds and wait for 30 seconds before repeating the process.

Remove the jumper cables exactly in the reverse sequence as for clamping.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the bat-
tery supplying the power must not be significantly less than the capacity of
the discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and
insulated terminal clamps. Obey the instructions of the jump start cable manu-
facturer.
Positive cable - colour coding in the majority of cases is red.
Negative cable - colour coding in the majority of cases is black.
