WARNING
High voltage systems in the electric motor compartment can cause electrical shocks or even electrocution, severe burns, other serious injuries, and even death!
x Never short-circuit the electrical system. Be especially careful when using jumper cables. The vehicle's battery could explode!
x To reduce the risk of electrical shock and personal injury while the electric motor is acti-vated:
– Never touch ignition cables. Never touch other components of the high voltage elec-tronic ignition system.
– Never touch the wiring of the HID – High Intensity Discharge (Xenon) headlights.
x Read and heed the important information and warnings on cleaning the electric motor
compartment ⇒ Cleaning the electric motor compartment.
WARNING
Moving parts in the electric motor compartment can cause serious personal injury on con-tact.
x Never reach into the area around or touch the radiator fan. Contact with the blades can cause serious personal injury. Always remember that the radiator fan is temperature-controlled and can come on suddenly even when the electric motor has been switched off for a while and the key has been removed from the ignition.
x If you have to perform a check or repair when the electric motor is activated, there are more risks from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always use extreme care.
– Always make sure that jewelry, loose clothing and long hair do not get caught in rotat-ing electric motor parts. Before starting any work remove your jewelry, take off your neck-tie, tie back and cover your hair, and do not wear clothing that can hang down and get caught in moving electric motor parts.
– Always use extreme caution if the accelerator pedal has to be depressed to perform a check. The vehicle will start to move even if the parking brake is on.
x Never leave any objects in the electric motor compartment, for example cleaning rags and tools. Objects left behind can cause malfunctions, electric motor damage, and even fires.
WARNING
Additional materials in the electric motor compartment such as blankets can interfere with the operation of the electric motor and can cause fires, which can lead to serious injuries.
x Never cover the electric motor with blankets or other materials.
WARNING
Operating fluids and some materials in the electric motor compartment can catch fire easily, causing burns and other serious personal injuries!
x Never smoke near the electric motor compartment.
x Never work next to open flames or sparks.
x Never pour or spill operating fluids or other flammable liquids on the electric motor. These fluids can ignite on hot electric motor parts and cause injuries.
x Always have a functional, approved fire extinguisher nearby.
should always be replaced by a qualified technician, since the vehicle's onboard electrical system management has to be reset after replacing the battery. Only a qualified service facility is able to perform this necessary adjustment. Therefore, Volkswagen recommends to always have the 12 volt vehicle battery replaced by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Only use maintenance-free vehicle batteries meeting standards TL 825 06 and VW 7 50 73. These standards must date from July 2012 or later.
Disconnecting the 12 Volt vehicle battery
If the battery must be disconnected from the vehicle's electrical system, note the following:
x Switch off all electrical systems and devices and the ignition.
x Unlock the vehicle before disconnecting the battery; otherwise the alarm system will go off.
x First disconnect the negative cable (-) and then the positive cable (+) ⇒ .
Connecting the 12 volt vehicle battery
x Prior to reconnecting the battery, switch off all electrical systems and devices and the ignition.
x Connect the positive cable (+) first and then the negative cable (-) ⇒ .
After the battery is connected and the ignition is switched on, different indicator lights may light up. They should go out after you drive a short distance at 10–12 mph (15–20 km/h). If the indicator lights do not go out, contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility and have the vehicle checked.
If the battery was disconnected for a long time, the next scheduled service may not be correctly calcu-
lated and displayed ⇒ Instrument cluster. The maximum permissible service and maintenance inter-
vals are shown in the ⇒ Booklet Warranty and Maintenance.
Vehicles with Keyless Access
If the ignition will not start after reconnecting the vehicle battery, lock the vehicle from the outside and
unlock it again ⇒ Unlocking or locking the vehicle with Keyless Access. Then try to start the ignition again. If the ignition cannot be switched on, contact an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop for assistance.
Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent onboard electrical system management automatically takes steps to help prevent battery drain.
x The idle speed is increased so that the alternator provides more power.
x The power to devices that consume a lot of electricity is cut back or switched off completely.
The onboard electrical system management cannot always keep the battery from being drained. For example, the battery will drain if the electric motor is not activated, but the ignition is switched on or the parking lights are left on for a long time when parked.
What drains the vehicle battery?
x Long periods when the electric motor is not activated, especially when the ignition is on.
x Using electrical systems or devices when the electric motor is switched off.
x Leaving the vehicle unlocked for several days when not in use.
x The selector lever is left for a long period of time in any position other than Park (P) when the
ignition is switched off ⇒ Selector lever.
