• Have a qualified workshop check the gas system for leaks and proper function every two years. .,.
Equipment, California 233

The batteries will become depleted if electrical consumers such as the auxiliary heater, refrigera-tor box or interior lights are used while the vehicle is stationary for long periods of time without re-charging the batteries. If the battery voltage falls below 11.5 volts, the auxiliary heater cannot be switched on.
The battery compartment and the battery charger are designed specifically for the factory-fitted AGM (absorbed glass mat) batteries &.
Additional batteries
r--f'n First read and observe the introductory information and safety warnings & on page 242.
The factory-fitted AGM batteries are located under the left front seat and in the wardrobe. They have deep discharge protection.
Should the additional batteries be subjected to deep discharge over a long period of time, they could be destroyed.
You can prevent deep discharge by:
• switching off the central control panel after charging,
• removing the fuses for the fresh water pump and the pop-up roof as necessary 249.
AGM batteries are maintenance free. do not leak their electrolyte, are robust and have extremely low gas emissions.
When should the additional battery be charged?
• If the additional battery is not charged by the al-ternator while the engine is running, the additional battery must be charged on the battery charger at regular intervals -every 4 weeks at the latest-for at least 12 hours.
• The additional battery must be recharged for at least 12 hours before the start of a journey if the battery has not been used for an extended period (e.g. seasonal use).

Dual clutch gearbox DSG®
r-('n First read and observe the Introductory L-.lo:on Information and safety warnings & on page 260.
Description
The DSG® dual clutch gearbox is a gearbox which uses dual-clutch technology to change gear automatically. it uses a dual clutch and two independent gearboxes to enable very fast gear changes with no loss of torque. The DSG® dual clutch gearbox thus combines the performance and economy of a manual gearbox with the com-fort and convenience of a conventional automatic transmission.
How the system works
Engine power is transferred to the drive shafts via the gearbox. In order to change gears, the power transmission between the engine and the gearbox has to be interrupted. This is what the clutch is for.
With the DSG® dual clutch system with its two complementary gearboxes, one gearbox is always connected under load to the engine. When one gear is engaged, another gear is always preselec-
led in the other gearbox. The clutch on the non-driven gear is closed and the other is opened at the same time. This is what makes very fast gear changes possible.
The DSG® dual clutch gearbox is designed to be more efficient than an automatic gearbox. In an au-tomatic gearbox, the torque converter is constantly in use, whereas in the DSG® dual clutch system the idle clutch can be opened, thus saving fuel. With its efficiency, low weight and intelligent control system, the DSG® dual clutch system usually ena-bles fuel consumption equal to or lower than a manual gearbox.
like the manual gearbox, the clutch in the DSG dual clutch system is subject to wear. Regular maintenance is necessary, varying accord-ing to what type of DSG® dual clutch system is in-stalled. For more information see the service schedule. In the DSG® dual clutch system, if one gearbox malfunctions it is deactivated and the oth-er gearbox functions alone *page 267. If this happens, have the system checked as soon as possible by a qualified workshop. DSG® dual clutch gearbox: selecting a gear
