Jump starting a Audi Q4 35 e-tron
There are convenient terminals to connect the positive and negative battery cables, which will be marked accordingly. Hook the positive up to the vehicle with the dead battery first, then to the vehicle you are jumping from.
Something to keep in mind: Traditional jumper cables are typically designed to handle the high amperage load of a starter motor. However, in the case of a hybrid vehicle, you are only attempting to power the 12-volt bus and therefore do not require such heavy-duty cables. It is recommended to use cables with a gauge size no larger than 14 – small motorcycle battery clamps should be sufficient.
