230-volt grounded safety socket
The 230-volt grounded safety socket is supplied with 230 V alternating current via electrical feed from the external socket 242.
The following electrical consumers are supplied from the 230-volt power supply via the external socket:
• Battery charger
• Depending on the vehicle equipment, the 230-volt grounded safety socket is located in the side trim panel behind the left front seat or on the side of the kitchen unit 246.
230-volt Euro socket
The 230-volt Euro socket is supplied via additional batteries or via an inverter and is located in the side trim panel behind the left front seat 245.

• Do not insert any items which will conduct electricity, such as knitting needles, into the contacts of the 230-volt Euro socket.
A WARNING
Improper use of the sockets and electrical ac-cessories can cause fires and severe Injuries.
• Never leave children in the vehicle unat-tended. Sockets and the devices connected to them can be used when the ignition is switched on.
A WARNING (Continued)
• If the electrical device gets too hot, switch off the device Immediately and disconnect it from the socket.
CD
• Observe the operating instructions for any device that you plug into the socket.
• Never exceed the maximum power rating as this could damage the whole vehicle electrical system.
• Only use accessories that have been ap-proved in accordance with valid guidelines concerning electromagnetic compatibility.
• Never feed electricity into the socket.
• Do not plug any heavy devices or connec-tions, such as mains adapters, directly Into the socket.

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).
248 I Before the JOurney
A WARNING
If a conventional battery Is charged it will give off a highly explosive mixture of gases.
• Use only AGM batteries of the same type (batteries with the electrolyte absorbed Into a special fibreglass matting) and with the same specifications as the factory-fitted batteries.
• Never use conventional batteries (wet cells with liquid electrolyte). A WARNING

The supplementary heating system is supplied with fuel from the vehicle fuel tank and can be used when the vehicle is in motion or stationary. Electri-cal power is supplied by the vehicle battery.
The auxiliary air heater runs in air recirculation mode and heats the vehicle interior. it has sepa-rate vents in the passenger compartment =>Fig. 265.
The auxiliary coolant heater heats the heating circuit. Heat is guided into the vehicle interior via the vents for the heating or air conditioning system. With the auxiliary coolant heater, it is possible to switch between heating and ventilating.
Additional information and warnings:
• Supplementary heater in the California =>page 192
• Filling the tank =>page 340
• Battery =>page 362
Swallowing batteries with a diameter of 20 mm or other lithium batteries can result in severe or even fatal injuries within a very short period of time.
• Always keep the vehicle key, key ring with batteries, spare batteries, round cells and other batteries that are larger than 20 mm out of the reach of children.
332 I While driving
• Call for medical help immediately you pect that someone has swallowed a batte
A WARNING
The fumes from the supplementary heating system contain carbon monoxide, which is an odourless and colourless poisonous gas. Carbon monoxide can cause people to lose consciousness. lt can also cause death.
• Never start or run the supplementary heat-ing system In unventllated or closed rooms.
• Never program the supplementary heating system so that Is switched on and run In un-ventilated or enclosed areas.
A WARNING
Parts of the exhaust system of the supple-mentary heating system become very hot. This can cause fires.
• Park the vehicle so that no part of the ex-haust system can come Into contact with any Inflammable material underneath the vehicle, e.g. dry grass.
Q)
Do not place any food, medicine or any other temperature-sensitive items in front of the vents. Heat-sensitive food, medicine and other items could be either damaged or rendered useless.
m After starting the engine with a discharged W vehicle battery, or after the battery has been changed, system settings (time, date, personal convenience settings and programming) may have been changed or deleted. Check and correct the settings as necessary once the vehicle battery has been sufficiently charged.

Switching the supplementary heating system on and off

Replacing the battery for the remote control
Auxiliary air heater: the battery is located on the back of the remote control underneath a cover 266 [ID. Pull off the cover® towards the rear.
Auxiliary coolant heater: the battery is located on the back of the remote control underneath a cover 267 [ID. Use a flat object, e.g. a coin, to turn the slot anti-clockwise in order to open the cover
®-
When changing the batteries, ensure you insert them the right way (poles) and that they are the same type
Range
The receiver is located in the vehicle interior. The remote control key has a range of several hundred metres when the battery is fully charged. The range of the remote control key can be considera-bly reduced by obstacles between the remote con-trol key and the vehicle, bad weather conditions, and a flat battery.
To achieve optimal range, hold the remote control vertically with the aerial 266 or 267 at the top. Do not hold the aer-ial with your fingers or the palm of your hand.
The distance between the remote control and the vehicle must be at least 2 metres.
CD
• The remote control contains electronic com-ponents. Protect the remote control from mois-ture, excessive vibration and direct sunlight.
• Unsuitable batteries can damage the remote control. Only replace discharged batteries with a new battery of the same voltage rating, size and specification.
Discharged batteries must be disposed of in W accordance with regulations governing the protection of the environment.
The battery in the remote control may contain W perchlorate. Please comply with legislation regarding disposal.
