- Fig. 1 Jump-starting with the battery of another Audi A3: -A- – Discharged battery, -B- – Boosting battery
The two jump leads must be connected in the correct sequence.
Plug-in hybrid drive*: The position of the terminals for the jump-start cable is different ►Link.
The battery is located at the front left of the engine compartment. Open the cover to access the positive terminal of the battery. Never jump-start a battery which has frozen, even after it has thawed WARNING!! If a battery has frozen it must be replaced. Please note that the described method of connecting the leads is meant for jump-starting your Audi A3.
Preparations
Please read ►Link carefully before proceeding.
Apply the parking brake and move the gear lever to neutral (manual gearbox) or move the selector lever to P (automatic gearbox).
Switch off all electrical equipment and the ignition on both Audi A3s.
Connecting and disconnecting the jump leads
Connect one end of the red jump lead to the positive terminal -1- Fig. 1 of the discharged battery -A- Caution!.
Connect the other end of the red jump lead to the positive terminal -2- of the boosting battery -B-.
Connect one end of the black lead preferably to the earth point or alternatively to the negative battery terminal -3- on the Audi A3 providing assistance -B-.
Connect the other end of the black jump lead only to the earth point -4- of the jump-start connection on your Audi A3 -A- Caution!.
Position the jump leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting the engine
Start the engine of the Audi A3 with the boosting battery and let it run at idling speed.
Start the engine of the car with the discharged battery and wait two or three minutes until the engine is running smoothly.
If the engine fails to start: do not operate the starter for longer than 10 seconds. Wait for about 30 seconds and try again.
Switch on the blower and the rear window heating on the Audi A3 which has been jump-started in order to offset excessive voltage which may occur when disconnecting the leads. The headlights must be switched off!
Disconnect the leads in exactly the opposite sequence to that described in ►Link with the engines running. Make sure that the leads cannot come into contact with any moving parts in the engine compartment.
Switch off the blower and the rear window heating again.
Please refer to WARNING!.
Do not use the negative battery terminal when jump-starting (this could cause a malfunction in the on-board electrical system).
Note
- Connect the battery clamps so they have good metal-to-metal contact with the battery terminals.
- The battery is vented to the outside to prevent gases entering the Audi A3's interior.
