If and when -> Jump starting for Your Volkswagen E Golf 4 Door Second Generation (2017-2020)

Jump starting  
Introduction to the topic  
If the vehicle’s drive system cannot be activated because the 12-volt vehicle battery is  
discharged, you can use the 12-volt vehicle battery in another vehicle to activate the vehicle’s  
drive system.  
Suitable jump leads are needed for jump starting.  
Cable cross-section for the jump leads:  
For vehicles with an electric drive at least 25 mm2  
WARNING  
Using the jump leads incorrectly or completing the jump start procedure incorrectly can cause  
the 12-volt vehicle battery to explode, which can lead to severe injuries. Please note the  
following in order to reduce the risk of the 12-volt vehicle battery exploding:  
All work on the 12-volt vehicle battery and the electrical system can cause serious chemical  
burns, fire or electric shocks. Always read the warnings and safety information before  
carrying out any kind of work on the 12-volt vehicle battery (→ 12-volt vehicle battery,  
Introduction/General information).  
The vehicle battery providing assistance must have the same voltage (12 volts) and  
approximately the same capacity as the flat 12-volt vehicle battery (see label on battery).  
Never charge a 12-volt vehicle battery which is frozen or has been frozen. Discharged 12-  
volt vehicle batteries can already freeze at temperatures of around 0°C (+32°F).  
The 12-volt vehicle battery must be replaced if it is frozen or has ever been frozen.  
A highly explosive mixture of gases is given off when the 12-volt vehicle battery is jump  
started. Always keep fire, sparks, naked flames and lit cigarettes away from the 12-volt  
vehicle battery. Never use a mobile telephone when the jump leads are being connected or  
disconnected.  
Position the jump leads so that they never come into contact with any moving parts in the  
engine compartment.  
Never confuse the negative and positive terminals or connect the jump leads incorrectly.  
Observe the jump lead manufacturer's instructions.  
NOTICE  
Please note the following in order to avoid considerable damage to the vehicle electrical  
system:  
A short circuit can be caused if the jump leads are wrongly connected.  
The vehicles must not touch each other, as any contact could mean that electricity could  
flow as soon as the positive terminals are connected.  
Jump lead connection point (earth connection)  
Fig. 1 In the engine compartment: jump lead connection point (earth connection).  
There is a jump lead connection point (earth connection) in the engine compartment for  
connecting the black jump lead Fig. 1 .  
The vehicle can only be jump started via this jump lead connection point (earth connection).

Suitable earth connection: preferably the jump lead connection point (earth connection), a  
solid metal part which is securely bolted onto the cylinder block, or the cylinder block itself.  
The discharged 12-volt vehicle battery must be properly connected to the vehicle electrical  
system.  
The vehicles must not be touching each other. Otherwise electricity could flow as soon as the  
positive terminals are connected.  
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.  
If the vehicle’s drive system cannot be activated, stop the procedure and repeat it after  
approximately one minute.  
Please contact an expert if the vehicle’s drive system still cannot be activated.  
Attaching the jump leads  
The jump leads should be connected only in the order A – B – C – D Fig. 1 .  
The black jump lead should never be connected to the negative terminal on the 12-volt vehicle  
battery. Connecting the lead to the negative terminal can cause incorrect condition evaluation of  
the 12-volt vehicle battery in the vehicle electronics.  
Switch off the ignition in both vehicles (→ Deactivating the vehicle’s drive system, Operation).  
Connect one end of the red jump lead to the positive terminal + of the vehicle battery with the  
discharged 12-volt vehicle battery Fig. 1 1 →  
.
Connect the other end of the red jump lead to the positive terminal + of the vehicle battery  
providing assistance Fig. 1 2 .  
Connect one end of the black jump lead preferably to a suitable jump start connection point  
(earth connection) or otherwise to a solid metal part that is securely bolted onto the cylinder  
block, or to the cylinder block itself of the vehicle providing assistance Fig. 1 3 .  
On the vehicle with the flat 12-volt battery, connect the other end of the black jump lead  
preferably to the jump lead connection point (earth connection), or otherwise to a solid metal  
part that is securely bolted onto the cylinder block, or to the cylinder block itself Fig. 1

.
Position the leads in such a way that they cannot come into contact with any moving parts in  
the engine compartment.  
Activating the vehicle’s drive system  
Start the engine of the vehicle that is supplying power and let it run at idle, and start the  
ignition in the electric vehicle.  
Activate the electric drive on the vehicle with the discharged 12-volt vehicle battery.  
Please contact an expert if the vehicle’s drive system cannot be activated.  
Removing the jump leads  
Before disconnecting the jump leads, switch off the dipped beam headlights if they are  
switched on.  
When the engines are running, the jump leads should be removed only in the order D – C – B –  
A Fig. 1 .  
Close the battery cover as required.  
Go to a qualified workshop without delay and have the 12-volt vehicle battery checked.  
WARNING  
Jump starting the vehicle incorrectly can cause the 12-volt vehicle battery to explode, which  
can lead to serious injuries. Please note the following in order to reduce the risk of the 12-volt  
vehicle battery exploding:  
All work on the 12-volt vehicle battery and the electrical system can cause serious chemical  
burns, fire or electric shocks. Always read the warnings and safety information before  
carrying out any kind of work on the 12-volt vehicle battery (→ 12-volt vehicle battery,  
Introduction/General information).  
Always wear suitable eye protection and gloves and never lean over the 12-volt vehicle  
battery.  
Attach the connecting cables in the correct order – the positive cable first, followed by the  
negative cable.  
Never connect the negative cable to parts of the high-voltage system or to the brake lines.  
The non-insulated parts of the battery clamps must not be allowed to touch each other. The  
jump lead attached to the positive terminal on the 12-volt vehicle battery must not touch  
electrically conductive parts of the vehicle.  
Check the battery window on the 12-volt vehicle battery, using a torch if necessary. If it is  
light yellow or colourless, do not jump start the vehicle. Seek expert assistance.  
Avoid electrostatic discharge in the vicinity of the 12-volt vehicle battery. The explosive gas  
emitted from the 12-volt vehicle battery could be ignited by sparks.  
Do not use jump leads if the 12-volt vehicle battery is damaged or if it is frozen or has been  
frozen.  
NOTICE  
Once the vehicle has been successfully jump-started, go to a qualified workshop and have the  
12-volt vehicle battery checked.
