- Fig. 1 Engine compartment: Terminals for jump leads and battery charger
- Fig. 2 Jump-starting with the battery of another Audi A5: A – Boosting battery, B – Discharged battery
The two jump leads must be connected in the correct sequence.
The jump-start terminals are located in the engine compartment Fig. 1.
Connecting the positive terminals with the positive lead (red)
Open the red cap on the positive terminal Fig. 1.
Connect one end of the lead to the jump-start terminal Fig. 2 -1- (terminal under red cap = "positive") of the Audi A5 with the flat battery -B-.
Connect the other end of the positive lead to the positive terminal -2- of the boosting battery -A-.
Connecting the negative terminals with the negative lead (black)
Connect one end of the negative lead to the negative terminal -3- of the boosting battery -A-.
Connect the other end of the lead to the jump-start terminal -4- (terminal with hexagon = "negative") of the Audi A5 with the flat battery -B-.
Starting the engine
Start the engine of the Audi A5 with the boosting battery -A- and let it run at idling speed.
Now start the engine of the Audi A5 with the discharged battery -B-.
If the engine fails to start: do not operate the starter for longer than 10 seconds. Wait for about 30 seconds and try again.
When the engine is running, disconnect the leads in exactly the opposite sequence to that described above.
Refit the red cap onto the positive terminal.
The battery is vented to the outside to prevent gases entering the Audi A5's interior.
Connect the battery clamps so they have good metal-to-metal contact with the respective terminals.
WARNING!
- The non-insulated parts of the battery clamps must not be allowed to touch. The jump lead attached to the positive battery terminal must not touch metal parts of the Audi A5: this can cause short circuiting.
- Do not bend over the batteries - risk of acid burns.
- The screw plugs on the battery cells must be screwed in firmly.
- Keep sparks, flame and lighted cigarettes away from batteries: the gases given off can cause an explosion.
- If jump-starting another Audi A5, position the jump leads in such a way that they cannot come into contact with any moving parts in the engine compartment of the other Audi A5.
Caution!
Please note that the above method of connecting the leads is meant for jump-starting your Audi A5. If jump-starting another Audi A5, you should not connect the negative lead (–) to the negative terminal of the discharged battery, but directly to the engine block or a solid metal part bolted to the engine block. If the battery of the other Audi A5 does not have a gas vent, there is a risk that a mixture of oxygen and hydrogen gas can accumulate and cause an explosion.
