Colour dis-Action play
Light yellow The electrolyte level of the vehicle
or without is too low. The vehicle battery
colour should be checked and replaced by a qualified workshop if necessary.

A WARNING
Any work on the vehicle battery can cause serious chemical burns, explosions and elec-trlc shocks.
• Always wear eye protection and protective gloves.
A WARNING (Continued)
• Electrolyte is very aggressive. lt can burn the skin and can cause blindness. When working with the battery, ensure that your hands, arms and face in particular are protec-ted from acid spillages.
• Never tilt the vehicle battery. Electrolyte may spill out of the battery vents and cause chemical burns.
• Never open a vehicle battery.
• if acid is spilt in your eye or on your skin, rinse immediately for several minutes with cold water. Then consult a doctor immediate-ly.
• If acid is swallowed, consult a doctor im-mediately.

Charging the battery
The vehicle battery should always be charged by a qualified workshop, as the technology used in fac-tory-fitted batteries requires voltage-limited charg-ing => &. Volkswagen Commercial Vehicles recom-mends using a Volkswagen Commercial Vehicles dealership for this purpose.
If the battery cannot be charged in a qualified workshop, the charging cables of a suitable battery charger must be connected as described in =>page 443, Jump starting for vehicles with a Start/Stop system.
Replacing a vehicle battery
The battery has been developed to suit the condi-tions of its location and has special safety features. If a vehicle battery has to be replaced, discuss the electromagnetic compatibility, size and necessary servicing, output and safety requirements for the new vehicle battery with a Volkswagen Commercial Vehicles dealer before purchase. The vehicle bat-tery should be replaced by a qualified workshop. Volkswagen Commercial Vehicles recommends us-ing a Volkswagen Commercial Vehicles dealership for this purpose.
Only maintenance-free vehicle batteries compliant with the standards TL 825 06 and VVV 7 50 73 should be used. These standards must be dated July 2012 or later.
Vehicles with a Start/Stop system =>page 282 or auxiliary heater =>page 332 are fitted with a special vehicle battery. These vehicle batteries may only be replaced by a vehicle battery with the same specifications.
Disconnecting the vehicle battery
Please note the following if the vehicle battery has to be disconnected from the electrical system in the vehicle:
• Switch off all electrical consumers and the igni-tion.
• Unlock the vehicle before disconnecting the battery in order to avoid triggering the alarm.
• First disconnect the negative cable and then the positive cable => &.
Connecting the vehicle battery
• Switch off all electrical consumers and the igni-tion before reconnecting the vehicle battery.
• First reconnect the positive cable and then the negative cable=>&.
Various indicator lamps may light up after the vehi-cle battery has been connected and the ignition is switched on. They will go out if you drive a short distance at a speed of 15-20 kmlh (10-12 mph). If the indicator lamps remain lit up, the vehicle should be checked by a qualified workshop.
if the vehicle battery was disconnected for long pe-riods, the system may not able to calculate or cor-rectly display the time when the next service is due =>page 19. Comply with the maximum permissible service intervals =>Booklet Service schedule. ""
In the engine compartment 365
r'l11 First read and observe the Introductory L-J,:.,U Information and safety warnings & on page 443.
CD Vehicle with discharged battery that is being jump-started.
@ Vehicle with vehicle battery that is supplying power and jump-starting the other vehicle.
@ Suitable earth connection. A solid metal part that is firmly bolted to the engine block, or the engine block itself.
The discharged vehicle battery must be properly connected to the vehicle's electrical system.
The vehicles must not touch. 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 engine does not start immediately, switch off the starter after about 10 seconds and try again af-ter about half a minute.
The steps should only be carried out in the speci-fied order.
Attaching the jump leads
• Switch off the ignitions In both vehicles 257.
• If necessary, open the battery cover in the en-gine compartment 362.
• Connect one end of the red jump lead to the positive terminal 318 E) or 319 E) of the vehicle with the discharged battery CD &.
• Connect the other end of the red jump lead to the positive terminal E) In the vehicle providing as-sistance@.
• In vehicles without start/stop system: con-nect one end of the black jump lead to the negative terminal 0 in the vehicle providing assistance @ 318.
• In vehicles with start/stop system: connect one end of the black jump lead @to a suitable earth connection, to a solid metal part which is se-curely bolted onto the cylinder or to the cylinder block itself =:-Fig. 319.
• Connect the other end of the black jump lead @ to a solid metal component that is bolted firmly to the engine block of the vehicle with the flat bat-tery, to the engine block itself or, if necessary, to the screwed-in towing eye at the front. Do not con-nect it to a point near the battery CD &.
• Position the leads in such a way that they can-not come into contact with any moving parts in the engine compartment.
Starting the engine
• Start the engine of the vehicle which is provid-ing assistance and let it run at idle.
• Start the engine of the car with the discharged vehicle battery and wait two or three minutes until the engine is running "smoothly".
Removing the jump leads
• Before disconnecting the jump leads, switch off the dipped beam headlights If they are switched on.
• Turn on the heater blower and rear window heater in the vehicle battery with the discharged battery. This helps minimise the voltage peaks generated when the leads are disconnected.
• With the engines running, disconnect the jump leads in the exact reverse order to the instructions given above.
A WARNING
Jump starting the vehicle Incorrectly can cause the battery to explode, which can lead to serious injuries. Please note the following In order to reduce the risk of the battery ex-ploding:
• All work on the 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 vehicle battery 362, Vehicle battery.
• Always wear suitable eye protection and never lean over the vehicle battery.
• Attach the connector cables In the correct order-the positive cable first, followed by the negative.
• Never connect the negative cable to parts of the fuel system or to the brake lines.
• The non-insulated parts of the battery clamps must not be allowed to touch. The jump lead attached to the positive vehicle battery terminal must not touch metal parts of the vehicle.
• Check the battery window using a torch If necessary. If the display Is light yellow or col-ourless, do not jump start the vehicle. Seek expert assistance.
• Avoid electrostatic discharge In the vicini-ty of the vehicle battery. The gas emitted from the vehicle battery could be Ignited by sparks.
• Do not use jump leads to start the engine If the vehicle battery Is damaged or if it is or has ever been frozen.
