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

In some vehicles, the locations of fuse blocks could vary from the those shown In the table. How-ever, since the order of the amp ratings is identical within any individual fuse block, you will still be able to identify the electrical consumers if this is the case.
The fuses for the camping equipment electrical consumers are located under the left front seat 214. Other vehicle parts will have to be re-moved in order to gain access to the fuse box. If you are unsure, have the fuses changed by a qualified workshop.
Several electrical consumers could share a single fuse. Conversely, a single consumer could have more than one fuse.
Therefore fuses should only be replaced when the cause of the fault has been rectified. If a new fuse blows shortly after insertion, have the electrical system checked by a qualified workshop as soon as possible.

The brake support systems are the anti-lock brake system (ASS), the Brake Assist system (SAS), the electronic differential lock (EDS), the traction control system (TCS) and the Electronic Stability Control (ESC).
Additional information and warnings:
• Towing a trailer 139
• Pull-away assist systems 282
• Wheels and tyres 367
• Accessories, modifications, repairs and renewal of parts 394
A WARNING
Driving with worn brake pads or with a faulty brake system can cause accidents and seri-ous Injuries.
• If the warning lamp 0 lights up either on its own or with a text message In the display of the Instrument cluster, go to a qualified workshop Immediately, have the brake pads checked and any worn brake pads replaced.
A WARNING
Incorrect parking can cause serious Injuries.
• Never remove the vehicle key from the lg-nltlon lock when the vehicle Is In motion. The steering lock may be activated and you will no longer be able to steer or control the vehl-cl e.
A WARNING (Continued)
• Never park the vehicle where parts of the exhaust system can come into contact with inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt fuel.
• Always apply the handbrake when the ve-hicle Is parked.
• Never leave children or people requiring assistance alone In the vehicle. They could release the handbrake, move the selector lev-er or gearshift lever and thus set the vehicle In motion. This can lead to accidents and se-rious injuries.
• Always take all vehicle keys with you ev-ery time you leave the vehicle. The engine can be started and electrical equipment such as the window controls can be used which could cause serious injury.
• Never leave children or people requiring assistance alone in the vehicle. They could become trapped in the vehicle in an emergen-cy and may not be able to get themselves to safety. For example, locked vehicles may be subjected to very high or very low tempera-tures, according to season. This can cause serious Injuries and illness or fatalities, espe-cially for small children.
CD
• To avoid unintentional movement when parking the vehicle, first apply the handbrake and then remove your foot from the brake ped-al.
• Always take care when driving in car parks with protruding kerbstones or bollards. Objects that protrude from the ground can damage the bumper and other components when parking the vehicle. In order to avoid any damage, stop the vehicle before the wheels can touch the bollards or kerbs.
• Drive carefully through dips in the road, over driveways, ramps, kerbstones and other objects. Low-lying vehicle components such as the bumper, spoiler and parts of the running gear, engine or exhaust system could be dam-aged.

A WARNING (Continued)
• If the brake warning lamp ID does not go out, or if it lights up when driving, the brake fluid level in the reservoir is too low or there is a fault in the brake system. Stop the vehi-cle Immediately and seek expert assistance 277, Brake fluid.
• If the brake warning lamp@ lights up to-gether with the ABS indicator lamp S, the control function of the ABS may have failed. This can cause the rear wheels to lock quick-ly when you brake. Locked rear wheels can lead to a loss of control of the vehicle. If pos-sible, reduce your speed and drive carefully at low speed to the nearest qualified work-shop in order to have the brake system tes-ted. Avoid sudden braking and driving ma-noeuvres on the way.
• The ABS Is not functioning correctly if the ABS indicator lampS does not go out or comes on while the vehicle is in motion. The

• If the warning lamp 0 lights up either indi-vidually or together with a text message in the display of the instrument cluster, go to a qualified workshop immediately to have the brake pads checked or any worn brake pads replaced.
CD
Failure to observe illuminated indicator lamps and text messages can lead to your vehicle be-Ing damaged. A WARNING
Incorrect use of the handbrake can cause ac-cidents and serious Injuries.
• The handbrake should never be used to brake the vehicle, except in emergencies. The braking distance is considerably longer as only the rear wheels are braked. Always use the foot brake.
• Never drive the vehicle with the handbrake lightly applied. This can overheat the brakes and adversely affect the brake system. lt can also cause premature wear to the rear brake pads.
• Never activate the accelerator from the en-gine compartment if a position or gear has been selected and the engine is running. The vehicle can start to move even if the hand-brake Is applied.

Fig. 226 Fuel consumption in litres per 100 km at two different outside temperatures.
r-1"'11 First read and observe the Introductory Information and safety warnings&. on page 278.
By adopting an economical driving style and antici-pating the traffic situation ahead, you can easily re-duce fuel consumption by 10-15%.
Cars use most fuel when accelerating. If you think ahead when driving, you will need to brake less and thus accelerate less. Wherever possible, let the car roll slowly to a stop, for instance when you can see that the next traffic lights are red.
Avoid short journeys
Directly after a cold start, the engine has a very high fuel consumption. The engine reaches its working temperature after a few kilometres, when fuel consumption will return to a normal level.
The engine and catalytic converter need to reach their proper working temperature in order to mini-mise fuel consumption and emissions. The out-side temperature is a key factor.
The different rates of fuel consumption for the same distance at both +20"C (+68"F) and at -10"C (+14"F) are shown in Fig. 226.
Therefore, avoid making too many short journeys and car share whenever possible.
Under the same conditions, the vehicle will use more fuel in winter than in summer.
280 I While dnvmg
Not only is it illegal in some countries to "warm up" the cold engine by running it while the vehicle is stationary, it is also technically unnecessary and a waste of fuel.
Adjust the tyre pressure
The correct tyre pressure reduces rolling resist-ance and therefore also fuel consumption.
Ensure that any new tyres purchased have opti-mum rolling resistance.
Use low viscosity engine oils
Fully synthetic low viscosity engine oils reduce fuel consumption. Low viscosity engine oils decrease frictional resistance in the engine and spread bet-ter and more quickly, especially for cold starts. They are especially effective In vehicles that make alotofshortjourneys.
Always ensure that the engine oil level is correct and that you keep to the service intervals (oil change intervals).
When buying engine oil, always make sure it com-plies with engine oil norms and has been approved by Volkswagen Commercial Vehicles.
Avoid unnecessary loads
Lighter vehicles are more economical and have lower environmental impact. An extra 100 kg, for example, can increase fuel consumption by up to 0.311100 km.
Remove all unnecessary objects and loads from the vehicle.
Remove any unnecessary special equipment and accessories
The more aerodynamic a vehicle, the lower its fuel consumption. Special equipment and accessories, such as roof carriers or bicycle carriers, make the vehicle less aerodynamic.
You should therefore remove any special equip-ment and luggage carriers that are not in use, es-pecially if you are going to be driving at high speeds.

• On vehicles with Climatronic: if the temperature inside the vehicle substantially increases or de-creases.
• When the vehicle starts rolling or brake support is required.

The Hill Descent Assist system supports
the driver when driving down a steep in-
cline by actively braking the vehicle.
The Hill Descent Assist reduces the engine speed and brakes actively so that the vehicle travels con-stantly at walking speed =>&.
The requirement for regulation is, among other things, that the ground allows enough grip. The Hill Descent Assist system cannot fulfil its function when driving down an icy or slippery slope.
Hill Descent Assist is regulating
• If the Hill Descent Assist is switched on using the button and the indicator lamp lights up.
• AND: the speed is less than 30 km/h (19 mph).
• AND: the gradient is at least 10%.
• AND: if the accelerator and brake are not de-pressed.
• AND: if the engine is running.
Regulation is stopped if the vehicle is accelerated or braked by the driver during regulation. The regu-lation restarts once the requirements are met again.
Hill Descent Assist does not regulate
• If the gradient is less than 10%.
• OR: The speed is greater than 30 km/h (19 mph).
• OR: If the driver brakes or accelerates.
A WARNING
Always be prepared to brake the vehicle. Ac-cidents and Injuries could occur if this is not ensured.
• The Hill Descent Assist system is only a support function and may not be able to brake the vehicle sufficiently In all situations when driving downhill.
• The vehicle may accelerate despite the Hill Descent Assist system.
