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.

Different engines require different fuels. The facto-ry-fitted sticker on the inside of the tank flap indi-cates the fuel type that is required for your particu-lar vehicle.
Volkswagen Commercial Vehicles recommends us-ing fuels with a low sulphur content or which are sulphur-free in order to reduce fuel consumption and prevent damage to the engine.
If the engine is not running smoothly or begins to judder, this can indicate poor or inadequate fuel quality, e.g. water in the fuel. If these symptoms appear, reduce the vehicle speed immediately and drive to the nearest qualified workshop at medium engine speeds, avoiding high engine loading. If these symptoms occur immediately after the vehi-

Preparing the vehicle for working in the engine compartment . . . . . . . . . . . . . . . . . 352 Opening and closing the bonnet 352
Always park the vehicle on a level and stable sur-face before carrying out any work in the engine compartment.
The engine compartment of a motor vehicle is a hazardous area. Never carry out any work on the engine or in the engine compartment if you are not familiar with the requisite procedures and general safety requirements, or if you only have access to incorrect operating equipment, service fluids, and unsuitable tools &. The work should be carried out by a qualified workshop if you are uncertain. Serious injuries can be caused if work is carried out incorrectly.

A wARNING
Unintentional vehicle movements during service work can cause serious injury.
• Never work underneath a vehicle if it is not secured against rolling away. If you are working underneath the vehicle while the wheels are on the ground, the vehicle must

be on a level, the wheels must be blocked and the vehicle key must be removed from the ignition lock.
• If you have to work underneath the vehi-cle, use suitable stands to provide extra sup-port for the vehicle. The vehicle jack is not sufficient for this task and can fail, which can lead to serious injuries.
• The start/stop system must have been de-activated.
A WARNING
The engine compartment of any motor vehi-cle is a dangerous area. Serious injuries can be sustained here.
• The utmost care and attention must be paid when carrying out any work and you must follow the general safety rules. Never take any risks.
• Never do any work on the engine or in the engine compartment unless you know exact-ly how to carry it out. If you are uncertain of what to do, the work should be carried out by a qualified workshop. Serious Injuries can re-sult from work that has not been carried out properly.
• Never open the bonnet if you see steam or coolant escaping from the engine compart-ment. Hot steam or coolant can cause seri-ous burns. Always wait until you can no lon-ger see or hear steam or coolant coming from the engine compartment.
• Always allow the engine to cool down be-fore opening the bonnet.
• Hot parts of the engine or exhaust system can burn the skin.
• The following points should be noted be-fore opening the bonnet once it has cooled down.
-Apply the handbrake fully and move the selector lever to position P or move the manual gear lever to the neutral position. .,..

A WARNING (Continued)
-Remove the vehicle key from the igni-tion lock.
-Always keep children away from the en-gine compartment and never leave the ve-hicle unattended.
• The engine cooling system Is under pres-sure when the engine Is hot. Never open the cap of the coolant expansion tank when the engine Is hot. Coolant may spray out and cause serious burns and other Injuries.
-Turn the cap slowly and very carefully anti-clockwise while exerting gentle down-ward pressure on the cap.
-Always protect the face, hands and arms from hot coolant or steam with a large, thick cloth.
• When refilling, do not spill any service flu-ids on engine components or on the exhaust system. The spilt service fluids can start a fire.
A WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries and death!
• Never short circuit the electric system. The vehicle battery could explode.
• Please note the following guidelines to help reduce the risk of an electric shock and serious Injuries while the engine is running or being started:
-Never touch the electrical wiring of the Ignition system.
A WARNING
There are rotating components in the engine compartment that can cause serious injury.
• Never place your hand near these compo-nents or In the radiator fan. Touching the ro-tary blades can result in serious injuries. The fan Is temperature-controlled and can start automatically, even if the engine has been switched off and the vehicle key has been re-moved from the ignition lock.
• If any work has to be performed when the engine Is started or with the engine running, there is an additional, potentially fatal, safety risk from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from the high-voltage ignition system. Always be particularly careful.
A WARNING (Continued)
-Always ensure that no body parts, jew-ellery, ties, loose items of clothing or long hair can be caught up in rotating engine components. Before starting work, re-move any jewellery and ties, tie up long hair and pull clothes In tightly to avoid them getting caught In the engine com-partment.
-Always depress the accelerator careful-ly and never without due consideration. The vehicle can start to move even if the handbrake is applied.
• Always ensure that you have not left any objects, such as cleaning cloths and tools, in the engine compartment. Any forgotten items can cause malfunctions, engine damage and fires.
A WARNING
Additional insulating materials such as cov-ers in the engine compartment could disrupt the operation of the engine, cause damage and lead to severe Injuries.
• Never cover the engine with any Insulating materials.
A WARNING
Service fluids and some materials In the en-glne compartment are highly flammable and can cause fires and serious Injuries!
• Never smoke while working on the vehl-cl e.
• Never work near naked flames or sparks .
• Never spill fluids onto the engine. They could Ignite on hot engine components and hence cause injuries.
• Please note the following when carrying out any work on the fuel system or the elec-trlcal system:
-Always disconnect the vehicle battery. Ensure that the vehicle Is unlocked when the vehicle battery Is disconnected as oth-erwlse the anti-theft alarm will be activa-ted.
-Never work in the direct proximity of heating systems, water heaters or any oth-er open flames.
• Always have a fully functional and tested fire extinguisher to hand.
